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。

The first and the second workshops of the series were held at City University of Hong Kong in December 1998 and Banff, Alberta, Canada in May 2000, respectively.

主要的原因是：Maple是符号计算领域里能力最强的软件包，而MATLAB*在数值和工程计算领域也是最优秀的软件。

In addition, by calculating the bioaccumulation factor, the result shows that bioaccumulation ability of the Phragmites australis varies among the tissues, and the bioaccumulation ability of the root tissue that is prone to accumulate Pb and Cd is much higher than the stem and leaf tissues which are easy to concentrate Pb.

生物富集系数的计算结果显示，芦苇不同组织对有毒重金属元素的生物富集能力存在较大差异，根组织的生物富集能力最大，且容易富集Pb和Cd；而茎、叶组织的生物富集能力较低，易富集Pb。

However, the capability of a single computer cannot fulfill the requirements of the large scale computing, and High Performance Computing becomes the only approach for it.

然而，单个计算机的能力远远不能满足大规模科学与工程计算的要求，高性能并行计算成为实现这种计算的唯一途径。

This is obtained by detailed calculations, in a manner somewhat similar to that for displacement calculations and varies in detail for individual regulations; tonnage measured according to the tonnage regulations may, therefore, be slightly different from the actual volume of the spaces below the tonnage deck calculated for, say, cargo capacity.

这是得到了详细的计算方式，有点类似于位移的计算和不同的个人详细规定；吨位衡量按照吨位规例可能，因此，稍有不同的实际数量的空格甲板下方的吨位计算的，也就是说，货运能力。

The research results show that the steam inlet pressure and water inlet temperature are the main factors which affect the lifting-pressure performance; the steam injector have the characteristics of self-adaptive outlet pressure and constant outlet flow rate; the theoretical maximum lifting-pressure coefficient calculated could be high as 14 and the experimental value is 3.0, which could be high as 1.5 even if the water inlet temperature is high as 95℃. The noise of steam injector could be induced from 80db to 50db.

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
