During the course of acid rain eluviation, Zn shows the most activation. Although Zn does not seem to be obviously anomaly, it has the highest concentration in soil solution and eluviation solution, the most activation heavy metal element in acid rain effect. Other elements including Hg, As, Cd, Cu, Pb etc.

已有大量研究结果表明，冲积平原区土壤中的Hg异常主要与Org.C有关，本次试验中又在土壤天然重砂中发现了辰砂矿物，Hg的上述存在形式特征决定了它在酸雨淋滤过程中的活动特性。3、酸雨作用下离子的迁移过程客观存在，这一点从土壤电导率研究结果中得到了确认。

Autoimmunity hypothesis of schizophrenia figures schizophrene has a certain degree of immunological functional disturbance,Hypothalmu- pituitary- adrenal axis can produceimmunosuppression. Hydrocortisone,the production of HPA axis,serve as important medium of immunosuppression, so we presume that hydrocortisone possibly induce immunological dysfunction of schizophrene.

精神分裂症的自身免疫假说认为精神分裂症患者存在一定程度的免疫功能低下，而下丘脑-垂体-肾上腺轴功能紊乱被认为是引起免疫抑制作用的主要机制之一，其中皮质醇是免疫抑制作用的重要介质，因此我们推测精神分裂症患者可能存在有皮质醇含量增高有关。

Bifurcation and choas of the zigzag sampled phase detect frequency synthesizer;2. When incidence coefficient is afunction of the time,the parameter rogions in which the models appear choas behavior are given.

该文研究了Lin Weimin等人给出的一类具有非线性传染力的SIRS模型，证明了在某些参数区域内极限环的存在性和唯一性，以及在传染系数与时间有关时，模型存在混沌性态的参数区域。

When there was no thrombin, aptamer probes could hybridize with molecular beacons in the highest degree, generating the largest fluorescence signal; when thrombin was introduced, the hybridization of molecular beacons and probes was depressed, and the depressing degree was associable with the concentration of thrombin.

没有凝血酶存在时，识体探针可以和分子信标最大程度地杂交，使得分子信标的荧光信号上升；当存在凝血酶时，与凝血酶孵育结合后的识体探针再与分子信标作用，分子信标被打开的程度有所降低，并且打开程度的降低程度与凝血酶浓度有关。

Under the Town Planning Ordinance, no person shall undertake or continue a development in a development permission area unless the development was a use in existence before the gazetting of the relevant Interim DPA or DPA plans, or is permitted under the DPA plan or the replacement OZP, or has obtained permission from the board.

根据《城市规划条例》，任何人不得在发展审批地区内进行或继续进行发展，除非该项发展用途在宪报刊登有关的中期发展审批地区图或发展审批地区图之前已经存在，或是有关的发展审批地区图或取而代之的分区计划大纲图所准许的，又或已获得城市规划委员会的规划许可。

As for the writing of India, there exit some complicated and intricate historical relations between colonial literature and post-colonial literature , which is related to the Orientalist attitude of British writers and Indian-British writers.

殖民文学与后殖民文学在书写东方印度主题方面，存在一些复杂微妙的历史联系，存在着历时性和共时性的&东方&话语，这与一些英国作家和印裔英国作家的东方主义心态有关。

3D effect is analyzed and the average velocity of wave propagating in the pile, which mainly influences inverse interpretation, is discussed. Finally, the theory results are verified by model experiment. It is shown that 3D results have the same phase with ID results. The pile radius, the duration of impulse, the ratio of hammer radius to pile radius and shear velocity of the soil around the pile have influences on 3D effect. The best position of receiver is 0.55R from the pile center. The average velocity of wave propagating in the pile reduces due to transversal inertia effect and 3D effect.

结果表明：三维曲线与一维结果在相位特征上一致；波场图直观地反映了波在桩中的传播规律；三维效应与桩径、激振脉冲宽度、相对激振半径及桩周土剪切波速有关；传感器放在0.55R处可以得到干扰较小的信号；三维效应和横向惯性效应的存在会使桩中的波速减小，土的性质对波速影响不大；反演精度与缺陷的性质、激振条件有关。

The results showed that the forming of calcium ions was a significant factor affecting the pitch deposition, and the deposition was related to not only the amount of calcium soaps but also their dispersion, and the better the calcium soaps dispersion, the less the deposition, pH value influenced the pitch deposition significantly.

研究结果表明，Ca~(2+)的存在是造成树脂沉积的重要因素，树脂沉积的多少不但与钙皂的多少有关，而且还与其在体系中的分散程度有关，钙皂分散得越好，树脂沉积越少。

This study shows that there is a liner relationship among the earthquake magnitude, epicentral distance and abnormal signal amplitude of the geoelectric field recorded at Wenxian station. For the signals with bandwidth of 0.003-30 Hz, the duration time of the anomaly is related to the lead time and the azimuth of epicental location.

研究表明，对于文县地电场观测点而言，震级、震中距、异常电信号幅度之间存在着线性关系；对带宽为0.003-30 Hz的异常信号而言，震前异常的时间长短与异常开始至发震时刻的时间长短存在着密切关系，且与震中方位有关。
