We firstly summarize the NN system modeling methods and the popular optimization algorithms, and point out the deficiencies, the limitation of noise cancellation modeling and the need of human intelligence participation, in our former optimization work after analysis. An abstract problem is extracted. It is to find out control variant that makes system output optimized using the data comprising a sample set with N x samples and their corresponding y, and it does not explore given system and achieves full automatic computation procedure. Next we propose a multi-variant controlled system optimization method utilizing CASSANDRA-I small type neural computer and program its application software. Moreover systematic experiments are made to demonstrate the method's validity, ability of noisy samples disposal and practical application.

我们总结了神经网络系统建模方法以及得到广泛采用的优化算法，并分析指出我们前阶段的优化工作中存在的去噪声建模有局限性和计算过程需人干预的不足，在此基础上把问题抽象为：已从系统获得含N个控制量样本的样本集S以及每个样本对应的系统输出，如何依据这些数据求出一个使系统输出y得到优化的控制量x，而不研究具体系统，实现不需要人智能参与自动完成的计算过程；提出应用人工神经网络硬件系统——CASSANDRA-I小型神经计算机的多变量控制系统优化方法，设计完成了其应用软件；并进行系统的实验工作，验证算法的有效性以及此方法处理带噪声样本和实际应用能力。

This paper shall attempt to look at some aspects of controller synthesis for the multivariable servomechanism problem when the plant to be controlled is subject to uncertainty-in this case,a controller is to be found so that satisfactory regulation/tracking occurs in spite of the fact that the parameters of the plant may be allowed to vary,subject only to the condition that the resultant perturbed system remains stable.

The next, the components withdrawed from PLS regression process are not all ideal, and among them there is a kind of component which has bigger covariance, however this component is weak in accounting for the dependent variables, which is primarily due to the fact that the independent variables is sneaked into more excrescent influences in that the variance becomes bigger.

其次，从偏最小二乘法运算的过程所提取的成分并不都是理想的，其中就有一种成分，他的协方差较大，主要是因为自变量系统中混入了较多的异常影响，从而造成其方差较大，但成分对响应变量的解释能力却不强。

With regard to the government interference question, economics often takes it as an economic variable quantity. As in economics, adopting different premising hypothesis will lead to different conclusions, which means that economics only explains various possible choices of government interference. Choice of certain government interference mode only reflects the economist's value tendency to a great extent.

对于政府干预问题，经济学往往把其作为一个经济变量来看待，由于在经济学中，采用不同的前提性假设会导致不同的结论，这意味着，经济学只是对政府干预的诸多可能的选择进行解释，某种政府干预模式的选择很大程度上仅仅反映经济学家本人的价值观倾向。

When we used those two multivariate statistic analytical techniques to study the spatio-temporal variation laws of benthic community structure at Shenzhen Bay, the results indicated that: 1 There was not obverse difference in intertidal benthic community structure between Futian, Shenzhen and MaPi, HongKong in Shenzhen Bay in Spring, 2000. However, there was continual gradient change in community structure from outer bay to inner bay. 2 There was obvious deference with the respect of benthic community structure between station C and stations Al, A2, A3 in transect A and station B in transect CBA in Shenzhen Bay. There being no benthos at station C in Summary, 2000, it indicated that station C had been polluted very heavily. 3 Deferent seasons and deferent tide sites are the most two important factors which play influence on benthic community structure at stations Al, A2, A3 and B3 in Shenzhen Bay.

用这两种多变量方法研究深圳湾底栖动物群落结构时空差异，结果表明(1)2000年春季深圳湾底栖动物群落结构组成在深圳福田一侧与香港米埔一侧并没有明显的差异，而是沿湾外向湾内呈现连续的梯度变化；(2)在深圳福田一侧的C断面的底栖动物群落结构与A、B断面有明显的差别，2000年夏季在C断面没有采到任何底栖动物，表明C断面已经遭受了严重的污染；(3)季节和潮区是影响深圳湾A1、A2、A3、B3站位底栖动物群落结构组成时空差异的两个最重要的因素。

With these conclusions,we present an accurate algorithm to solve the simultaneous inequality of binomial PDF.An optimum solution can be worked out by adopting multivariate half-folded searching algorithm,so that we can get the sampling plan of testability demonstration accurately and quickly.
