“生物能力学”

科学通报 , 1963,
Abstract: 本书的特点是,它并非对生物能力学作詳尽的闡述,而是对未知的科学領域大胆地提出个人的見解与推測,并以通俗的解释引导讀者去思考生物物理与生物化学迫切等待解决的一些重要問題。作者在本书中提出了生物体內能力学过程的几个基本假說。他认为在生物現象中存在着两个不同的能量形式,即儲存在化合物中的“非活性”价鍵能和在生化过程中能传递和“迁移”的活性能量。生物对象中处于被束缚状态的水具有特殊的結构,这种水不仅是某种坚固的介貭,而且是一种有利于“活性”能积累和传播的介貭。作者更进一步指出:“活性”能也就是組成生活物貭的蛋白貭、核酸以及其他成分的分子或分子体系的电子激发能。作者力求

An Improved Femtocell Spectrum Allocation Algorithm
 [PDF]


Hans Journal of Wireless Communications (HJWC) , 2012, DOI: 10.12677/hjwc.2012.21005
Abstract: 家庭基站(Femtocell)被认为是下一代通信系统新兴技术之一,为我们解决室内覆盖问题提供了一种有效的方法。而要想在已经存在的宏蜂窝网络中成功的部署家庭基站系统,仍然面临许多问题,比如,小区之间的频谱划分来最大化频谱效率最小化小区干扰,切换和功率控制等。本文从频率复用的角度,将软频率复用方法(SFR)应用到Femtocell两层网络的频谱分配算法中,给宏小区的内部区域和外部区域分配不同的功率,提出一种改进的基于SFR的家庭基站频谱分配算法。仿真结果和分析显示我们所提出的频谱分配算法能够提高宏用户的性能,最小化家庭基站的配置对宏用户性能的影响,保证小区边界用户的性能,增大系统容量。
Femtocell is considered to be one of emerging technologies in next generation communication systems. It provides an effective method for us to solve the indoor coverage problem. However, deploying the femtocell system in the existing macrocell network still faces many problems, such as spectrum allocation between cells to maximize spectral efficiency to minimize cell interference, switching between cells and power control. In this paper, according to the frequency reuse method we use the soft frequency reuse (SFR) method to our two-tier femtocell network. Allocating different power to the internal area and external area of macrocell, we propose an improved femtocell spectrum allocation method. Simulation results and analysis showed that the proposed spectrum allocation algorithm can raise the performance of the macro users and increase the system capacity.

Abstract:
如何实现过渡金属高效催化噻吩裂解脱硫是石油加工环节的重大难题。在已有的实验基础上,我们利用Gaussian03程序,采用密度泛函理论(DFT),使用B3LYP方法在Genecp基组水平上研究了噻吩分子与四种过渡金属M = (Co, Ni, Cu, Zn)的吸附微观行为。计算结果表明:不同的过渡金属原子对噻吩分子的吸附存在着不同的吸附位,过渡金属Co与Cu吸附以α位为主,吸附后能量分别降低了479.621 kJ/mol和369.203 kJ/mol;过渡金属Ni吸附以β位为主,吸附后能量降低了高达671.241 kJ/mol;过渡金属Zn吸附以δ位为主,吸附后能量降低了165.094 kJ/mol,过渡金属Cu与Zn原子吸附噻吩分子还存在有θ位的吸附。吸附能量的计算应考虑零点能的校正。
How to realize high catalytic desulfurization of thiophene cracking of transition metals is the major problem of petroleum processing. On the basis of the existing experiment, we combine Gaussian03 progress with the density functional theory (DFT) and B3LYP method to study the thiophene molecular adsorb microscopic behavior on the four kinds of transition metal as M = (Co,Ni,Cu,Zn) on Genecp basis set level. Calculation results show that: different transition metal atoms of thiophene molecular adsorption, adsorption exists different; transition metal Co and Cu adsorption is given priority to with alpha, the energy of which after the adsorption decreased 479.621 and 369.203 kJ/mol respectively; transition metal Ni adsorption is given priority to with beta, the energy of which after the adsorption decreased as high as 671.241 kJ/mol; transition metal zinc adsorption to the delta is given priority to, the energy of which after the adsorption decreased after 165.094 kJ/mol; There is another adsorb behavior as θ position exists about thiophene molecule on the transition metal Cu and Zn. The calculation of adsorption energy should consider the zero-point energy correction.

 [PDF]


Advances in Social Sciences (ASS) , 2013, DOI: 10.12677/ASS.2013.23009
Abstract: 村民参与村务公开是基层民主监督的重要途径,也是村民自治的重要环节。村民主体地位的确立是实施村务公开的关键,只有激活村民的民主意识,突出村民的主体地位,畅通村民的意愿诉求渠道,才能加快农村民主进程的建设步伐。对村民的主体地位进行法律建构,加强村民在村务公开中的主体地位,不仅有利于村民参与村务公开,而且能够切实保障村民的知情权、参与权、监督权。
Villagers’ participation in open village affairs is an important way to promote the democracy supervision at the grassroots level, and also the important link of the villagers’ autonomy. The establishment of villagers’ subject status is the key to the implementation of open village affairs. Only by activating the villagers’ democratic consciousness, highlighting villagers’ subject status, and expediting villagers’ appealing channel, can the construction process of rural democracy be sped up. Conducting the legislative construction of villagers’ subject status and enhancing villagers’ dominant roles in open village affairs not only benefit the villagers’ participation in open village affairs, but also guarantee villagers’ rights to know, to participate, and to supervise.

The study of three-dimensional gravity forward of typical geological model was based on the two- dimensional gravity forward method. The sphere is presented as the main geological model, which derives two-dimensional and three-dimensional gravitational Bouguer anomaly, the gravitational anomaly formula of every derivative respectively. The two-dimensional and three-dimensional gravity anomaly curve was achieved in the MATLAB environment. Combining with the analytical method of two-dimensional gravity forward modeling, this paper conducted a three-dimensional gravity forward modeling analysis, as well as compared and discussed the advantages and disad-vantages of two-dimensional gravity forward and three-dimensional gravity forward, and then got the results that two-dimensional gravity forward can only reflect gravity information of geological vertical slice, while three-dimensional gravity forward can reflect gravity information of the whole geological body. Small local geological body can obtain its size and shape through analyzing high- order derivative.
