To avoid or reduce re-analysis, we derived the augmentative matrix variation only in summation of the previous matrices time the outside-perturbed parameters by decomposing the element stiffness and mass matrix. The implicit function of amplitude about design variables such as cross-areas and lengths is changed into simplistic function about the perturbed parameters of design variables. Several methods for determining the value of perturbed parameters are detailed.

为避免或减少重分析，将有限元单元阵进行了分解变换组装，使振幅与设计变量如截面面积、长度的复杂隐函数关系转化为对设计变量摄动参数的显式关系，进而将设计变量摄动参数提取在分解后的几个常数刚度阵、质量阵之外，避免了在迭代求解过程中重组刚度阵与质量阵，较快地获得问题的解。

Since the Ming Dynasty, that area has been transformed from marginalization to backland. The infiltration of the central power and the massive influx of immigrants began to impact on the traditional agricultural foundation. The ecological agriculture and the domestic animal farming was replaced step by step by ecological agriculture only, with large areas of land reclaimed and forest grassland resources used. This has put great pressure on the ecological environment in the northwest of Guizhou.

自明代以来，黔西北地区开始由边缘化向内地化转变，中央权力的渗透和外来移民的大量涌入，开始日益冲击着黔西北传统农业的根基，使黔西北农业兼畜牧型生态模式逐渐转化为农业为主体的生态模式，大批的荒地被开垦，森林植被和草场资源得到最大极限的利用，这给黔西北的生态环境造成了极大的压力。

Methods Guinea pigs were, to begin with, given MBP through the nasal route to induce the development of peripheral immune tolerance, and then immunized with specific antigen MBP plus complete Freund's adjuvant. The clinical symptoms of guinea pigs were investigated, and the erythrocyte rosette test, and lymphocyte blastogenesis test, the MBP-specific skin delayed-type hypersensitivity response and the levels of interlukin-4 (IL-4) and interferon-γ were also detected, and the pathological changes were examined as well.

On the establishment of shielding immune cells avoid HIV viral antigens identified protein adsorption and the establishment of "biological trap" induce HIV models Summary : HIV is the human immunodeficiency virus caused AIDS virus, AIDS is not currently be fully human control, AIDS vaccine is being developed, but because the virus genetic diversity potential to change the topic of the complexity of this ban from the incidence of HIV spread T4 cells in the mechanisms by, proposed changes T4 lymphocyte surface protein CD4 receptors structure as to avoid HIV adsorption, and the establishment of "biological trap" booby HIV idea to try to turn on AIDS treatment to the conversion of protein structure and function, as well as synthetic direction.

提要：HIV即人类免疫缺陷病毒是引起AIDS的病毒，目前爱滋病还不能被人类完全控制，AIDS的疫苗也正在研制中，但是由于病毒多样性的遗传潜能，使这一课题变的很复杂，本文试从HIV侵染T4细胞导致发病的机理入手，提出改变T4淋巴细胞表面CD4受体蛋白构象以避免HIV吸附，并设置"生物陷阱"诱杀HIV的构想，试图把对爱滋病的治疗引向对蛋白质结构与功能转化以及合成的方向。

A new non-linear quadratic programming Bayesian prestack three-terms inversion method is developed; Firstly, this method is based on Bayesian parameter estimation theory, Gaussian distribution is used for likelihood function and modified Cauchy distribution is used for prior distribution; Secondly, covariance matrix is used to describe the degree of correlation between the parameters; rock physics relations are used to constrain the inversion results; at last, this method is transformed into non-linear quadratic programming problem, and inversion results are acquired under several constraints.

本文提出了一种基于非线性二次规划的叠前三参数反演方法。首先基于贝叶斯参数估计理论，假设似然函数服从高斯分布，并使待反演的参数服从于改进的Cauchy分布，从而提高了反演结果的分辨率；其次用协方差矩阵来描述参数间的相关程度，进一步提高了反演结果的稳定性；最后将问题转化为一个非线性二次规划的求解问题，并在多种约束下得到问题的解。

The membership function can exactly express the fuzzy satisfaction set by considering the vagueness of satisfaction degree of objectives and introducing the membership function for the fuzzy satisfaction sets of system reliability and system cost. The normal distribution and Cauchy distribution of this membership function is modified according to the fuzzy satisfaction sets. By doing this, the multi-objective optimization problem can be converted to a single-objective optimization problem to be solved.

模型充分考虑到目标满意度的模糊性，通过引入系统可靠度与费用的模糊满意集的隶属函数，并根据它们的模糊满意集对其正态分布、柯西分布进行适当修改，使之能够准确表达通常情况下的这两个目标的模糊满意集，最终，把两目标优化问题转化为常规单目标优化问题求解。
