部分时间

Naturalism is a philosophical position which holds that all that exists is natural - in other words, is part of the spatio - temporal processes of nature - or, that if any sort of nonnatural object may exist, it is known only through its effects within nature.

自然主义是一种哲学的立场，认为所有的存在是很自然的-换句话说，是部分的时空-时间过程的性质-或，如果任何形式的非天然的对象可能存在的，这是众所周知的，只有通过其效果的性质。

This thesis is divided into six parts. The first chapter is preface, the current status of research in the inverse problems for parabolic partial differential equations is reported; the second chapter is "regularization methods for numerical differentiation and their applications ", in this chapter we investigate many regularization methods from a viewpoint of regularization theory and algorithm, some applications in the inverse problems for parabolic partial differential equations are given; the third chapter is "spectral regularization methods". Based on Fourier analysis, within the framework of regularization theory, we apply the spectral methods to some ill-posed problems. Many numerical experiments are done in order to show the validity of the methods; the fourth chapter is devoted to wavelet dual least squares method and a revised wavelet method; in the fifth chapter,we combine finite difference method with method of lines and apply it to the backward heat conduction problem in time; in the sixth chapter "identification problems for unknown source ", the essence and the degree of two problems related to source identification are pointed out, at the same time, some numerical methods are reported.

本文分为六个部分，第一章前言简要分析了国内外抛物型偏微分方程反问题的研究现状；第二章数值微分的正则化及其应用从正则化理论和算法的角度出发，考察了许多正则化方法，还给出了数值微分在抛物型偏微分方程反问题的一些应用；第三章谱正则化方法是在Fourier分析的基础上，在一般正则化理论的框架下，给出了这种方法在各种不适定问题中的应用，数值实验表明谱方法是有效的；第四章研究了小波对偶最小二乘方法和改进的小波方法；第五章主要研究了有限差分方法结合线方法在时间反向热传导问题中的应用；第六章是未知源识别问题，主要指出了两类未知源问题的不适定程度和不适定本质，同时报告了一些数值方法。

The partial oxidation of methane by the H5PV2Mo10O40 catalyst in oleum was studied. The effects of catalyst amount, reaction temperature, reaction time, and sulfur trioxide concentration on the methane conversion and methanol yield were investigated.

以H5PV2Mo10O40 为催化剂，在发烟硫酸中进行了甲烷液相部分氧化，考察了催化剂用量、反应温度、反应时间和发烟硫酸浓度等工艺条件对反应收率的影响。

Experiment of the third part use the first part"s production as carrier, selecting Geotrich candidum and Candida tropicalis of higher production of protein also selecting producing the cellulose enzyme Bacillus subtilis FS and Lactobacillus bulgaricus by ourselves separated, design orthogonal test and a series of single factor experiment, finally assurancing the inoculation quantity of four strains germ, is Geotrich candidum 5%, Candida tropicalis 5%,Bacillus subtilis FS 5% of FS, Lactobacillus bulgaricus 3%, the most suitable development temperature is 30 "C , the development time is 15 days.

实验的第三部分是以第一步共培养所得的培养物为载体，选择产蛋白量高的白地霉、热带假丝酵母及本室筛选的产纤维素酶芽孢杆菌FS和自行分离的保加利亚乳酸杆菌，设计正交实验和一系列单因素实验，最终确定了四株菌的接种量，分别为白地霉5%，热带假丝酵母5%，FS5%，保加利亚乳杆菌3%，最适培养温度为30℃，培养时间为15天。

Most of these people had been suffering from migraines since childhood, so the long-term overstimulation of the sensory fields in the cortex could explain these changes.

这些偏头痛患者大部分从小就有偏头痛发作，因此对这部分大脑皮层区的长时间的过度刺激能够阐释这种变化。

One thing you won't regret is taking time for this part of your life.

一件事你不会感到遗憾的是抽出时间为这部分你的生活。

Also aiding some partial return to the carry trade are rising chances of a rate hike by the Reserve Bank of Australia, which lifted the Aussie to a 10-week high of 80 cents. This weekend's rate hike by the People's Bank of China was a surprise in its timing but not in its actual outcome..

而且伴随这套息交易的部分回流，使澳大利亚联储银行升息的可能性增加，使得澳元汇价上升了达到了10周来的高点位置，本周中国人民银行的升息决定令人意外，不过意外的是其选择的时间，而不是升息的结果。

Experimental results show that,compared with full redundancy which replicates full error flow graph,partial redundancy can reduce register usage by 6.25%, reduce power dissipation by over 17%,reduces total execution cycles by nearly 26%,and improves performance by over 22%,at the cost of 6.25% lower nodes coverage.

实验显示，与复制全部错误流图的完全冗余相比，在结点覆盖率降低6.25%的情况下，部分冗余算法最多能够减少寄存器的使用数量6.25%，减少功耗超过17%，减少执行时间接近26%，同时提高性能超过22%。

It is also a good time to perform a partial water change.

这是一个好时间，以履行部分水分变化。
