As steady error coefficient is an important index in measuring system error, it is introduced into the performance index set. A solution of satisfactory biased estimation strategy is proposed by assuming that the maneuver of target is finite, which can ensure the accuracy and stability of the estimation output.

稳态误差系数是衡量系统误差的一个重要指标，于是本文将估计系统的动态误差系数纳入多指标约束，借助满意估计理论，在假定目标机动强度有限的前提下，给出了可兼顾滤波输出精度和平稳性要求的满意有偏滤波器的设计方法。

最后，借助概率统计方法，求得了六臂运动过程中定位的极限误差。

Compared with classical cytotoxic T lymphocytes , NK cells are superior in the following aspects: NK cells are among the first cell types to be activated after intracellular pathogen stimuli, the activity of NK cells peaked between 1 to 3 days, retained during the first 7-10 days, and the T cells response emerged only after 7 days when the NK cell responses begin to decline; though comprising of only 10％-15％ of peripheral lymphocytes, NK cells mobilize most of the cell populations in a strong and high level response to different invasions, and act as key factors at early defense before a specific immune response could mount, while only certain clones were involved in T cell response; NK cells kill virus-infected or malignant transformed cells without pre-sensitization and without restriction by major histocompatibility antigen, which is usually a mechanism of immune escape to T cell recognition by virus-infected or tumor cells, thus NK cell in complementary with T cells play crucial roles in tumor and virus eradication.

NK细胞以其强大的细胞毒活性为特征，与细胞毒性T细胞相比，NK细胞具有如下特点：NK细胞虽然只占外周血淋巴细胞的10-15％，但是对刺激性因素产生应答的过程十分迅速，一次可以调动大多数细胞共同参与，而不是几个克隆的活化，免疫应答的强度高；病毒感染或恶性转化细胞的一个主要特征是细胞表达的MHCⅠ类分子下降或消失，并借助这一机制逃避特异性T细胞应答的识别，NK细胞介导的杀伤活性无需抗原刺激，不受MHCⅠ分子表达的限制，从而与T细胞应答互为补充发挥免疫防御的功能；NK细胞的免疫活性可以被多种细胞因子上调，其中IFNα，IL-2，IL-12，IL-15和IL-18具备更强的作用；NK细胞具有强大的细胞因子分泌功能，对于启动T细胞特异性应答必不可少。

Adopting the network of radial basis function ormended BP network,the forecasting network model of stock on estimation region can beestablished.The stock of each pixel in estimation region can be calculated through simulationapproach,the total stock of compartment or sub-compartment can be obtained by way of theintegration to all pixels.

Against this background, the paper, with the research methods of ethics and economics, and looking into the question from the characteristics of economicality and ethicality, individuality and collectiveness of the mankind, analyzes the ethical connotations of economic cooperation, ponders on the ethical problems which hinder Cooperation, and discusses the solutions to these problems from the perspective of cooperative revenue, cooperative hazard, and cooperative trust, in an attempt to promote trust, reduce cooperative trust, and gain both ethical and economic benefits.

本文正是在这一背景下，主要运用伦理学的原理、并借助经济学的研究方法从人的"经济性"与"道德性"、"个体性"与"群体性"的特点入手，分析了经济合作的道德内涵，思索了困惑合作的道德方面的难题，并从合作利益、合作风险、合作信任等方面对问题的解决进行探讨，力图能够增进信任、降低合作成本，实现经济与道德的双重收益。

It employs the complex-valued step function to build neural model, then constructs network structure and decides the number of neurons; it adopts complex-valued Hebbian rules and inner product way to calculate the net weight matrix; then it analyzes the convergence of the network by taking advantage of the definition of energy function. In the image pre-processing stage, 2-dimensional Fourier Transform and Euler's formula are used, respectively, to transfer a gray-scaled image into phase information needed by the complex-valued neural network when stores the traffic sign. In the image post-processing stage, phase inverse transformation is used to change the phase image to gray-scaled image.
