The Optimal Solution of the Model with Physical and Human Capital Adjustment Costs

We prove that the model with physical and human capital adjustment costs has optimal solution when the production function is increasing return and the structure of vetor fields of the model changes substantially when the prodution function from decreasing return turns to increasing return. And it is shown that the economy is improved when the coefficients of adjustment costs become small.     

Photosensitized splitting of cis-syn 1,3-dimethyluracil dimer by tryptophan and its peptides

Photosensitized splitting of cis-syn 1,3-dimethyluracil dimer by tryptophan (Trp) and its peptides (Trp-Tyr and Trp-Phe) is studied by fluorescence quenching experiments and irradiation experiments.It reveals that 1,3-dimethyluracil dimer is mainly split by e?-?aq resulting from two-photon ionization of Trp and its peptides under irradiation with light (λ>290 nm).Moreover,the excited singlet state of Trp and its peptides can transfer an electron to the dimer,which splits and gives two pyrimidines.In addition,because of its lower oxidative potential,the excited triplet state of Trp-Tyr can also split the dimer via transfering an electron to the dimer.

拮抗肌对的协同控制与EMG信号的中值频率关系

探讨在持续恒力收缩时,正常人体肘关节主动肌和桔抗肌的协同作用原理与它们的表面EMG信号中值频率(Median Frequency,MF)的变化趋势,研究它们的疲劳行为。十五个正常受试者的实验数据统计结果表明,拮抗肌的SEMG/MF高于主动肌;随着收缩时间的增加,主动肌和拮抗肌的MF几乎以相同的速率下降;收缩力越大,它们的两条拟合直线之间的距离、互相关系数、下降速率也越大;关节的角度的变化对上述结论似乎没有明显的影响。这些结论对屈曲和伸展模式都成立。利用人体组织的幅度衰减特性和频率衰减特性,神经肌肉系统的“共驱动”概念对上述结果进行了讨论。

山西省入境旅游市场竞争态及转移分析

山西是全国旅游资源大省之一，拥有众多品位极高的旅游资源，但强大的资源优势并没有很好的转化为经济优势，这些年入境旅游业绩一直位居全国中下游．为了尽快改变这种状况，使山西入境旅游业得以加速发展，分析研究其市场状况就是很有必要的了．本文借助市场竞争态模型对2000年～2002年和2003年～2005年山西省入境旅游客源市场的竞争态势进行对比分析，并对山西省入境旅游市场竞争态进行动态分析．在分析的基础上，提出了拓展山西入境旅游市场的几点建议．     

急倾斜厚煤层掩护支架采煤法机械化问题的探讨

掩护支架采煤法是开采急倾斜厚煤层的有效方法之一,但回采工艺大多使用炮采。为进一步扩大急倾斜厚煤层掩护支架采煤法的适用范固,大幅度地提高技术经济效果,必须实现掩护支架下的采煤机械化。本文在总结分析国内外有关经验、资料的基础上,对掩护支架结构型式的改进和采煤机械化问题进行了初步的探讨,提出了设想方案。     

Static extracting method of software intended behavior based on API functions invoking

The method of extracting and describing the intended behavior of software precisely has become one of the key points in the fields of software behavior＇s dynamic and trusted authentication. In this paper, the author proposes a specified measure of extracting SIBDS （software intended behaviors describing sets） statically from the binary executable using the software＇s API functions invoking, and also introduces the definition of the structure used to store the SIBDS in detail. Experimental results demonstrate that the extracting method and the storage structure definition offers three strong properties： （i） it can describe the software＇s intended behavior accurately; （ii） it demands a small storage expense; （iii） it provides strong capability to defend against mimicry attack.     

Comparison of Drought-Resistance about Three Wild Rocky-Grasses

In this experiment, using the methods of drought-stress in the pot and PEG simulative drought-stress, three native rocky-slope grasses Pogonatherum panideum（Lam.） Hack, Erioophorum comosum nees and Cynodon dactylon cultivated in the pots were selected as materials to study their drought-resistance by analyzing the indexes such as the leaf area index, the drying roots accumulation, the holding water ability of leaf, the relative conductance of leaf, the soluble protein, chlorophyll. At the same time, by comparing with membership function value of each index, the order of each grass drought-resistance was decided. The results showed that the drought-resistance of Erioophorum comosum nees was stronger than Cynodon dactylon and drought-resistance of Cynodon dactylon was stronger than Pogonatherum panideum （Lam.） Hack. The purpose of the experimental results was to find theoretical foundations for selecting and cultivating native protecting-slope vegetations to adapt to rocky slopes.
