Huiying Song, Lingxiang Huang
Creative Education (CE) , 2012, DOI: 10.4236/ce.2012.37B016
Abstract:

In recent years, with the rapid development of economy and the continuous advancement of technology, the demand for high-level talents with expertise has been gradually increased in China. Master of Engineering (ME), the new education mode, has been developed rapidly. After briefing the status quo of the ME degree programs at home and abroad, this paper examines the current status of Master of Engineering degree programs in China from four aspects, namely the curriculum planning, graduation requirements, mentor qualities and the education system, by analyzing the results of a survey conducted in China’s universities. After pointing out the problems existed in the ME degree programs, this paper put forward four pieces of corresponding suggestions.

The Charge Storage of Doubly Stacked Nanocrystalline-Si based Metal Insulator Semiconductor Memory Structure  [PDF]
Xiang Wang, Chao Song, Yanqing Guo, Jie Song, Rui Huang
Modeling and Numerical Simulation of Material Science (MNSMS) , 2013, DOI: 10.4236/mnsms.2013.31B006
Abstract: Doubly stacked nanocrystalline-Si (nc-Si) based metal insulator semiconductor memory structure was fabricated by plasma enhanced chemical vapor deposition. Capacitance-Voltage (C-V) and capacitance-time (C-t) measurements were used to investigate electron tunnel, storage and discharging characteristic. The C-V results show that the flatband voltage increases at first, then decreases and finally increases, exhibiting a clear deep at gate voltage of 9 V. The de-creasing of flatband voltage at moderate programming bias is attributed to the transfer of electrons from the lower nc-Si layer to the upper nc-Si layer. The C-t measurement results show that the charges transfer in the structure strongly de-pends on the hold time and the flatband voltage decreases markedly with increasing the hold time.

Abstract: With the development of fuzzy measure theory, the integral inequalities based on Sugeno integral are extensively investigated. We concern on the inequalities of Choquuet integral. The main purpose of this paper is to prove the H?lder inequality for any arbitrary fuzzy measure-based Choquet integral whenever any two of these integrated functions f, g and h are comonotone, and there are three weights. Then we prove Minkowski inequality and Lyapunov inequality for Choquet integral. Moreover, when any two of these integrated functions f1, f2, , fn are comonotone, we also obtain the Hölder inequality, Minkowski inequality and Lyapunov inequality hold for Choquet integral.
Occurrence of Equatorial Plasma Bubbles during Intense Magnetic Storms
Chao-Song Huang
International Journal of Geophysics , 2011, DOI: 10.1155/2011/401858
Abstract: An important issue in low-latitude ionospheric space weather is how magnetic storms affect the generation of equatorial plasma bubbles. In this study, we present the measurements of the ion density and velocity in the evening equatorial ionosphere by the Defense Meteorological Satellite Program (DMSP) satellites during 22 intense magnetic storms. The DMSP measurements show that deep ion density depletions (plasma bubbles) are generated after the interplanetary magnetic field (IMF) turns southward. The time delay between the IMF southward turning and the first DMSP detection of plasma depletions decreases with the minimum value of the IMF Bz, the maximum value of the interplanetary electric field (IEF) Ey, and the magnitude of the Dst index. The results of this study provide strong evidence that penetration electric field associated with southward IMF during the main phase of magnetic storms increases the generation of equatorial plasma bubbles in the evening sector.

Huang, Mian;Zhang, Song;
Brazilian Journal of Microbiology , 2011, DOI: 10.1590/S1517-83822011000400015
Abstract: the study was conducted to evaluate effect of coriolus versicolor mycelia on degrading starch and improving nutrition value in corn grits through solid state fermentation technique. the results showed that using soybean meal as a nitrogen source, α-amylase secreted from c. versicolor expressed 407.25u/g of activity, leading to 45.15% of starch degraded. the activity grew with fermentation time until the 15th day, after that the amylase was deactivated rapidly. an orthogonal experiment designed for the study illustrated that degradation rate of starch in corn grits attained to maximum, 50.51%, when 100g of corn grits, added 16g of soybean meal, were fermented by c. versicolor for 12 days, in an initial ph 5.5. after fermenting, compared to the nonfermented control, contents of amino acids, total sugar, crude fat and crude protein were increased by 21.00%, 38.45%, 55.56%, 69.15% respectively. the significant improvement of nutrition value in corn grits is probably attributed to the intense metabolism of c. versicolor.

The intermolecular benzoin condensation catalyzed by bifunctional N-heterocyclic carbenes has been investigated, and the corresponding α-hydroxyketones were obtained with yields up to 76% and enantioselectivities up to 99% ee.
The geological heritages in Xinjiang, China: Its features and protection

HUANG Song,

地理学报 , 2010,
Abstract: The geological heritage protection and its development at home and abroad reflect the progress in the aspect from the single protection to the coordination between protection and exploitation. The geopark established by UNESCO has closely combined the protection of geological heritages with the promotion of sustainable development of local economy, which has become the best way to protect geological heritages. The geological heritages in Xinjiang, China, are characterized by their large quantity, rich variety and high grade. The complicated geologic-geomorphic environment in Xinjiang contributes to the creation of various geological heritage types and their spatial distribution, and at the same time makes them under control. The main types of the geological heritages in Xinjiang are the geologic- geomorphic landscapes and the water landscapes. The spatial distribution can be divided into five geological heritage districts: Altay, Junggar, Tianshan, Tarim and Kunlun-Altun, among which Tianshan and Kunlun-Altun are most important. Based on the first systematic investigation of the geological heritages in Xinjiang, it is confirmed that the insufficient coordination between protection and exploitation is the primary cause for the backward situation in the geological heritage protection. To solve the problem, this paper proposes 6 major protection steps—from determining the protection types, the protection forms, the protection modes, the protection grades, the protection sequences to determining the protection zones, brings forward the idea of optimal-selection which integrates geoparks with geological heritage protection areas and other protection areas as well as 5 corresponding modes, and makes a protection and exploitation reserve list for 209 important geological heritages in Xinjiang.

Glass Formation in Ni-Zr-(Al) Alloy Systems
Lanping Huang,Song Li
Journal of Materials , 2013, DOI: 10.1155/2013/575640
Abstract: Structural and thermal properties of binary ( ) alloys obtained by melt spinning and copper mold casting methods were investigated. The fully amorphous samples in a bulk form cannot be obtained in the binary Ni-Zr alloys over a wide composition range, though they have and values close to or even higher than those of the binary Cu-Zr bulk metallic glasses (BMGs). The low thermal stability of the supercooled liquid against crystallization and the formation of the equilibrium crystalline phases with a high growth rate are responsible for their low glass-forming abilities (GFAs). Relatively low thermal conductivities of Ni-based alloys are also considered to be another factor to limit their GFAs. The GFA of the binary Ni65.5Zr34.5 alloy alloyed with 4% or 5% Al was enhanced, and a fully glassy rod with a diameter of 0.5?mm was formed. 1. Introduction Bulk metallic glasses (BMGs) have attracted much attention due to their excellent properties compared with their crystalline counterparts and potential applications as structural materials [1–3]. A variety of BMGs with high glass-forming ability (GFA) based on multiple components have been developed over the past two decades or so [4–10]. Among these BMGs, ordinary Ni-based BMGs are very attractive for engineering applications because of their ultrahigh strength and relatively low cost. Ni-based amorphous alloys with diameters of more than 1?mm have also been produced since 1999 [11–16]. These Ni-based BMGs belong mainly to LTM-ETM (LTM-late transition metals, ETM-early transition metals) group of alloys. Now, their critical value of thickness is up to 15?mm, but metalloids included in some alloy systems have tampered their manufacturability. So, it is necessary to develop new Ni-based BMGs including only common metallic elements. Developing new Ni-based BMGs is expected to expand engineering applications and is important for understanding the long-standing issues of glass formation mechanism. Various empirical methods have been proposed to guide the discovery of BMGs with higher GFA [1, 10, 17]. The criterion widely used as a long-standing guideline has predicted that deep eutectics are preferable for glass formation upon cooling a liquid, so the compositions near the eutectics have been chosen preferentially to obtain BMG in either simple binary or multiple component systems. It is generally known that binary alloys must have a very high critical cooling rate required to avoid crystallization upon cooling from liquid state because of the simplicity of their chemical compositions. However, some binary alloys

The results of this study provide strong evidence that penetration electric field associated with southward IMF during the main phase of magnetic storms increases the generation of equatorial plasma bubbles in the evening sector. 1. Introduction Intense geomagnetic storms occur when the solar wind with strong, persistent southward interplanetary magnetic field (IMF) impacts on the Earth’s magnetosphere. The interplanetary electric field (IEF) associated with southward IMF penetrates to the equatorial ionosphere, creating an eastward electric field on the dayside and a westward electric field on the nightside. Penetration electric fields in the ionosphere have been extensively studied with the incoherent scatter radar chain including the Sondrestrom, Millstone Hill, Arecibo, and Jicamarca radars at ~75°?W geographic longitude, as well as with other space-based and ground-based measurements [1–14], and numerically simulated with global ionospheric models [15–18]. Huang et al. [6, 7, 14] and Huang [11] found that penetration electric fields in the ionosphere can last for several hours without obvious attenuation during continuous southward IMF. Huang et al. [8] reported that penetration efficiency, which is defined as the ratio of the change of the equatorial ionospheric electric field to the change of the IEF, is ~10% on the dayside. The purpose of this paper is to study how penetration electric fields affect the generation of plasma bubbles in the evening equatorial ionosphere during intense magnetic storms. Plasma bubbles are first generated in the bottomside F region and then penetrate the F peak to the topside F region [19–32]. However, the occurrence of equatorial plasma bubbles during magnetic storms has not been fully understood. In earlier studies, some investigators suggested that magnetic storms suppressed
