The main work of this paper: Firstly, Basing on the summarization and analysis of the walking mechanism, Parallel drive five-bar mechanism is applied for walking mechanism. And then the characteristic of the trail and positive kinematics as well as reverse kinematics are discussed. Secondly, the model of walking mechanism is established according to Parallel drive five-bar mechanism, and then a figure planning is designed for the foot-end trail. The characteristics of the parallel drive are emphasized to research in this paragraph by the method of insert value. At last, the simulation is performed in the ADAMS to compare the real result to the theoretical value. Thirdly, a sealed structure of a Quadruped Walking Robot is designed and established. The whole control system, including motor, sensor and control circuit, is sealed in the robot. Walking is derived in the way of the shaft driving and the dynamic torque sensor is used to the surrounding conditions of the robot's foot-end to be the foundation of the robot's control. At last, the applying principle of the dynamic torque sensor is researched in detail basing on the traditional sensor of the walking robot. Moreover, the principle is divided into several sorts to discuss. Finally, simulation and verification of the monitor principle are come through in the Mechanism of the Pro/Engineer.

Mowing suppressed seedling emergence of tall-growing Stipa krylovii by affecting seed availability due to reproductive parts removal when mown in the previous year, whilst exerted a positive effect on low-growing Cleistogenes squarrossa probably as result of increased light availability and less competitive pressure from adult individuals, because mowing largely lowered the vegetation height and density. 3."U"shaped curve for seedling mortality across the entire growing season was thought to be associated with seasonal changes of air temperature but a small peak from mid-June to early July could probably be attributed to drought due to previous rainfall shortage.

自5月下旬至8月中旬，三种禾草的实生苗密度总体上都呈上升趋势，但刈割和放牧会使克氏针茅的实生苗密度受到抑制，表明前一年的刈割去除部分生殖器官影响形成实生苗的种子来源；刈割和放牧对生长较低矮的糙隐子草实生苗会产生正向效应，对低矮和稀疏植被进行有规律的刈割会增加植物群落内部的光照，减轻实生苗与成年母株的竞争。

February 21, the China Disease Prevention and Control Center of respiratory specimens re-tested, the result, the avian influenza virus (H5N1) RNA positive.

The result showed that the main damage influence of diseases and worm was thick of ear, grains of row and the weight of one hundred grains, the grade of disease and the amount of worm had significant positive correlation to yield loss; the relationship of diseases and worm was complex, the yield loss of mixed damage was occupied 41.48% of the total damage of the single, the sequence was A＜C＜B＜D＜ABCD＜, the simulated models of mixed damage and economic threshold were developed.

研究表明，病虫为害主要影响穗粗、行粒数和百粒重产量构成因素，病级和虫量与产量损失呈显著正相关；病虫之间存在复合为害关系，复合产量损失率占四者单独造成产量损失率之和的41.48%，其大小依次为：A＜C＜B＜D＜ABCD＜，并组建了复合为害损失及复合经济阈值模型。

Result:2 patients with primary syphilis ,11 patients with syphilis after treatment, 7 patients with false positive, 7 patients with late latent syphilis perhaps.

结果：一期梅毒2例，已治愈的梅毒11例，假阳性7例，不能排除的晚期潜伏梅毒7例。

On the other hand, a higher frequency of CCR-64I allele was also observed in HIV-1 uninfected individuals who were heterosexually exposed to HIV-positive index partners (p=0.164), but most of the reports didn't support this result.

在异性传播病例中，有暴露史而未感染病毒者CCR2-64I的基因频率明显高于感染者，说明CCR2-64I对异性传播有一定的保护作用，不过与以往的研究不一致。多数研究认为，CCR2-64I对HIV-1异性传播无明显保护作用，有研究甚至认为是一种危险因素。
