When these coefficients are quadratic functions of the porosity, specific constituent orthogonal weighting coefficients are derived from these orthogonal conditions along with a discussion about how to extend the applicable range of the constituent orthogonal weighting coefficients in the orthogonal coordinates. Based on the combination of the theory of critical porosity and the constituent model, it presents a specific example of the constituent model that includes two transforming points. The reasonability of above-mentioned theories is shown by comparison of theoretical calculations and measured data on effective elastic moduli of clean sandstone or sandstone analogs saturated with pure water.

针对目前常用方法在解决负荷预测问题时,结果往往难以达到工程要求精度的现状,利用过程神经网络输入为时间函数以及预测精度高的特点,建立了基于过程神经网络的电力系统短期负荷预测模型;给出了模型的结构,基于函数正交基展开的离散数据拟合方法以及模型的学习算法。

This method prefilters input data by the orthonormal basis functions in order to get some dynamic characteristics. Unfortunately, the gradient algorithm could not be directly used in parameter identification because the prefiltered data do not have time shift characteristic anymore.

该方法通过正交基函数对输入数据进行滤波,使得滤波后的数据蕴涵着系统的部分动态特性,但也使滤波后的数据不再满足时移特性,因而无法直接使用梯度算法对模型参数进行辨识。

This method pre filters input data by the orthonormal basis functions in order to get some dynamic characteristics. Unfortunately, the gradient algorithm could not be directly used in parameter identification because the pre-filtered data do not have time shift characteristic anymore.

该方法通过正交基函数对输入数据进行滤波,使得滤波后的数据蕴涵着系统的部分动态特性,但也使滤波后的数据不再满足时移特性,因而无法直接使用梯度算法对模型参数进行辫识。

Their vocal quality is better than non-passerine, but still much less than oscine passerine. Compared with non-passerine, they appeared longer syllable length, higher basic frequency and more viable frequency ranges. Though the amplitude modulation properties enhanced their vocal production, the type of syllable is still stable and less of variety. So thephrase consisted of syllables are comparatively few and changes of the tone are relatively less.

且表现出很强的频率调制特性和特有的幅度调制特性,相对的音节时程比较长,基频较高且频率变化范围较大,所特有的幅度调制特性更增加了其控声的能力,但其音节的种类仍很单一,缺乏变化,由音节所组成的句型较少,音调变化幅度不大,因此,其叫声质量尽管较非鸣禽有所改善,但相对鸣禽而言却又远远不如。

Oxygen was found to be the best oxidant and almost no reaction was observed without adding any oxidant.

发现氧气是该反应较好的氧化剂,而没有氧化剂存在时,几乎没有羰基化反应发生。
