 Shu-Yin Chiang Mathematical Problems in Engineering , 2002, DOI: 10.1080/1024123021000053673 Abstract: In this paper, we study the simplified models of the ATM (Asynchronous Transfer Mode) multiplexer network with Bernoulli random traffic sources. Based on the model, the performance measures are analyzed by the different output service schemes.
 Shu-Yin Chiang Mathematical Problems in Engineering , 2006, DOI: 10.1155/mpe/2006/81950 Abstract: This paper develops the procedure for the analysis of the production systems with quality control devices. The evaluation of the production system requires an expression for the system performance measures as functions of the machine and buffer parameters. This paper presents a method for evaluating these functions and illustrates their practical utility using a case study at a production plant.

 遗传 , 1996, Abstract: 根据西藏当前大面积种植的9个棵大麦品种，运用数量遗传学的原理和方法，研究其主要性状的平均数、变异系数、广义遗传率、相关遗传率、遗传相关系数及表型相关系数，为提高今后育种效率提供一些信息。
 环境科学 , 2012, Abstract: 采用土培盆栽试验和室内分析相结合的方法,研究了Cu、Se复合污染土壤中2种金属的形态转化及其对生物有效性的影响.结果表明,在未污染土壤中,Cu主要以残渣态存在,Se主要以有机结合态和残渣态存在.在外源Cu、Se污染土壤中,平衡后(14 d),外源Cu主要以铁锰氧化物结合态存在,Se主要以可交换态及碳酸盐结合态存在; 小白菜收获后,土壤中的Cu向有机结合态转化,而Se向铁锰氧化物结合态转化.外源Cu与土壤结合程度(IR值)均随外源Cu和Se浓度升高而逐渐降低; 而Se与土壤结合程度(IR值)与外源Cu浓度无关,随外源Se浓度升高而下降.S型曲线拟合方程表明,适量的Se(≤10 mg ·kg-1)可以促进小白菜对Cu的吸收,同样适量的Cu(≤400 mg ·kg-1)能促进小白菜对Se的吸收.土壤的Cu、Se的IR值与小白菜体内Cu、Se含量呈显著负相关(P<0.05),小白菜种植前后土壤中可交换态和有机结合态铜和硒的变化量与小白菜地上、地下含量也呈显著相关(P<0.05).因此,土壤元素的IR值和作物种植前后该元素形态的变化量均可作为评价重金属生物有效性的指标.
 地球学报 , 2004, Abstract: 本文通过研究鲁西平邑磨坊沟金矿矿层，详细研究了围岩蚀变特征和成矿流体特征，结合硫、氧同位素资料，探讨了该矿床的成因机制。磨坊沟金矿呈似层状产于新太古代花岗闪长岩或古元古代二长花岗岩与寒武系主拆离滑脱带之上的早寒武世朱砂洞组碳酸盐岩中，围岩蚀变包括黄铁绢英岩化、方解石化和萤石化，金矿的形成主要与黄铁绢英岩化有关。成矿流体的均一温度集中于103～220℃之间，盐度在4．65％～13．18％范围内。从矿物成分看，该矿床属于碲金型金矿。同位素研究表明，矿层中硫来源于地幔，而氧同位素则显示其成矿过程有大气降水的参与。矿质迁移经过了鲁西幔枝构造中深、浅层次的拆离滑脱构造，最终卸载于次级拆离滑脱带断坪和断坡中。
 地球学报 , 1996, Abstract: Based on the geophysical prospecting, volcanic-magmatic activities, sedimentary formation and structural evolution in eastern part of North China platform, it is proposed that Hehuai area has been an intensively uplifted submantle plume since the Mesozoic. Duo to the intensive uplifting of the submantle plume, the lower lithosphere was thinned and the .upper crust was down faulted. Cenozoic sediments are up to 5-9km thick. The lithosphere was only 60-80km thick.The uplifting submantle plume was blocked at the bottom of lithosphere. The mantle plume.changed into half-spherical (shaped like a umbrella) and extended towards the surroundings. This made the middle-lower crust form gently declined detachmenting flow deformation layer (low velocity layer). As the mantle-crust interface gradually increased to 100-160km towards the surrounding, inadequate gravity resulted in uplifting of the crust and formed orogenic zone along the margin of the submantle plume. Meanwhile, the sharply declined ductile shearing zone in the axis of the orogenic zone cut off gently declined crust-mantle detachmenting flow deformation zone,the depressure and unloading made the soften rocks form anatectic magyna. Anatectic magyna melted some country rocks and intruded along the ductile shearing zone, this speeded up the uplifting of orogenic zone and formed the third class tectonic unit of the montle plume-mantle branch structure. The cover was openly detachmented in the place of quickly uplifting area. meta-morphosed basement rocks were exposed to form typical metamorphic core complex.Mineralization elements (such as An and Ag) which mainly came from the core moved up as gas with the mantle plume. In the submantle environment, some gaseous mineralization elements changed into liquid and moved up as gas-liquid mixture. When the umbrella-like extended submantle plume was cut off by sharply declined ductile shearing zone in orogenic belt, gas-liquid Au and Ag immigrated up with the anatectic magma along the ductile shearing zone and concentrated in favorable place to form industry deposits in mantle branch structure (metamorphic core complex).
 中国科学院研究生院学报 , 1994, Abstract: Examination on hairs and fruits of the Dimocarpus longan Lour. (Guiyuan) and D. confinis (How et Ho) H. S. Lo (magic fruit) was carried out. The fruit of D. longan was found to be of smoothly colliculate or granulate protuberances and typical tuft hairs on the surface, and the leaf was also of tuft hairs on the lower surface. However, the fruit of D. confinis was of dense and hard aculeate protuberances and simple and glandular hairs on the surface, and the leaf was also of the same kind of hairs on the lower surface. These char- acteristics of D. longan can been easily detected in samples of commercial fruits, which were misidentified as the fruits of D. confinis. Moreover, the fruit surface of Guiyuan Sampled from the markets had no any artificially destroryed trace, which indicated that they were not forged through the processing of the fruits of D. confinis, and thus they were trueGuiyuan, the fruit of D. longan.
 地球学报 , 2000, Abstract: Based on an analysis of characteristics and distribution regularities of geothermal anomalies as well as controlling factors of geothermal resources in north China basin,the authors hold that the uplifting of giant submantle plume is the main dynamic (thermal energy) source responsible for the crustal splitting, the formation and development of faulted depressions,and the evolution of geothermal field in north China. It is considered that the second-order uplifts and depressions in north China fault basin that led to geothermal gradient zoning are forms of tectonic control of geothermal resources.
