The exchange theorem of bases of closed regular fuzzy matroids is obtained with the help of "the exchange theorem of bases" of crisp matroids. Then,the relations between the fuzzy bases and the fuzzy circuits in closed regular fuzzy matroids are studied, and some necessary and sufficient conditions for some fuzzy independent set to be a fuzzy base; some fuzzy circuits from a fuzzy base, and some fuzzy bases from a fuzzy circuit are investigated.

根据传统拟阵的基交换定理，作者给出了闭正规模糊拟阵的基交换定理，得到了一系列结论，并在此基础上进一步研究了闭正规模糊拟阵的模糊基与模糊圈之间的关系，然后给出了闭正规模糊拟阵中某模糊独立集是模糊基、从一个模糊基得到一些模糊圈、以及从一个模糊圈得到一些模糊基的充要条件。

Reduced SQP based on orthonormal bases, orthogonal bases and coordinate bases are studied and compared. With the correction item introduced, the null-space move is adjusted and the reduced SQP based on coordinate bases decomposition is improved.●The key problem of steady-state data processing for RTOPT is studied. A new algorithm of simultaneous strategies for data reconciliation and gross error detection is proposed. Here the objective function that is constructed using maximum likelihood principle and joint distribution function is minimized. Efficient algorithm is developed which exploited the nonlinear lease-square structure of this objective function.

仿真结果表明了算法的有效性；●深入研究了在线优化中的一个关键问题——稳态数据处理问题，用基于组合概率分布的目标函数联立求解粗劣误差检测和数据调和问题；以精馏塔在线优化的数据处理和模型修正为例，提出一种根据模型方程对参数的依赖性进行过程模型分解的分层策略，可以将数据调和和参数估计统一在数据处理的大框架中，为进一步的过程性能分析、操作状况评价以及在线优化提供可靠的基准，具有非常重要的工程应用价值；●将优化命题的形式扩展到更通用的形式。

The choice of the best wavelet bases is one of the subjects attracting more attentions. This paper presents a new choosing method based on numerical analysis. Here the coding performance of wavelet bases is evaluated overall numerically by using several standards, which had been confirmed to be relating to image coding The best chosen wavelet bases fitting static images and video coding are respectively Daubechies's biorthogonal wavelet 9-7 and 5-3, which have been proved by coding experiments.

最佳小波基的选择是倍受关注的问题之一，本文提出一种新的基于数值分析的挑选方法，通过用几个已被证实是与图像编码密切相关的小波基评价标准对小波基的编码性能进行全面的数值评价，并经实际编码检验，选出了适宜静态与活动图像编码的最佳基分别为Daubechies双正交小波9-7与5-3。

Based upon the various conditions of the content, the charge and the equilibrium, the present paper has derived systematically five content equations according to different types of acids and bases as follows:Strong acids, weak acids, strong bases, weak bases and amphiprotic substances.

本文根据含量条件、电荷条件以及平衡条件，并按照各种酸碱的类型，分别系统地推导出五种含量方程式如下：强酸、弱酸、强碱、弱碱和两性物质。

What\'s more, different intervals of UV have their own characters in influencing DNA: the damage to some bases by UVA may be more serious than that by UVB, and UVB did more severe damage to some deoxyribose than UVA; however, as far as the pyrimidine bases are concerned, the damage by UVB is by far more serious than that by UVA. These results may indicate that there are preferential damaging sites on DNA molecules caused by UVA and UVB irradiation. Moreover, with UVA or UVB irradiation for a long time, the photoreactivation of DNA occurred. The serious damage to deoxyribose and bases by UVB and UVC may confirm the conformation of cyclobutane pyrimidine dimers and (6-4) photoproducts.

而不同波段紫外辐射对DNA的损伤各具特点并且差异明显，UVA对一些碱基的损伤比UVB要严重，而UVB在对脱氧核糖和磷酸盐的损伤上又比UVA要严厉，但就嘧啶碱基来说，UVB对它的损伤远大于UVA，这似乎表明了不同的紫外波段对生物大分子DNA的损伤是有选择性的。
