不纯一的

Theoretical Part: Through theoretical analysis of chemothermodynamics, combustion and engineering thermodynamics, factors that affect explosion limit were determined, which include temperature, pressure, spark ignition energy, electrode shape, direction of flame propagation and size of explosion vessel.

理论部分：根据化学热力学、燃烧学和工程热力学的基础理论，从本质上定性地分析了爆炸极限的影响因素，包括温度、压力、爆炸容器的大小、点火能量大小、以及火焰传播方向等，得出了这些影响因素对爆炸极限的影响规律，以确保实验有完整的理论基础指导；在此基础上本文提出了一种新的推算在常温常压下可燃性纯质和混合工质制冷剂爆炸极限浓度的理论方法，该方法由可燃性气体的化学组成来推算上下限浓度，不需要其它条件；对混合工质制冷剂，只要再知道混合配比，即可以推算出爆炸极限，使预测爆炸极限的工作更简单、方便。

A modified backward Euler method is developed which enables to increase considerably the accuracy of jump voltage computation as a result of freeing its computing from the influence of the faint asymmetrical initial current in such an inductive circuit as converter and completely eliminate numerical oscillation in converter simulation as often seen in the case of implicit trapezoidal integration method.

本文提出一种变形的后退欧拉法，用该法对换流器这样的纯电感电路进行跃变电压计算，可完全避免初始电流中微弱的不平衡对跃变电压计算的影响，大大提高了跃变电压的计算精度，并彻底消除了隐式梯形积公法用于换流器仿真时所存在的非原型数值振荡。

Kinetic equations of multibody systems with scleronomic constraint s are projected along the feasible and unfeasible directons of the constiaints respectively,and generalized accelerations of the systems are decomposed along the two directons using the bases of constraint matrix and its orthocomplement.

通过约束矩阵及其正交补的两组基，将定常约束多体系统的动力学方程沿与约束相容和不相容的两个方向上投影，并将系统的广义加速度沿这两个方向进行分解，得到描述系统运动的纯微分方程和求约束力的公式，同时提出了违约修正的一种方法。

Based on the depositional characteristics and stratigraphic feature of Inland Basins, Western China, and taken examples from Zhongger and Tsaidam basin, in this paper, the author probes systematically into syntheic methods applied to analysing subsurface sedimentary facies, predicting and mapping the source, reservoir and cap rock of oil/gas, and studing the stratigraphic model of sedimentary facies as well as the seismic models with all of information which come from outcrop section, drilling profiler, well log, seismic prospecting and examples data.

近十年来，作为有现代化测井技术、反射法地震勘探技术和计算机数据处理方法等参与的盆地油气勘探已为这一工作提供了新的信息并增加了新的分析内容，以地表露头剖面和钻井岩蕊观察为基础、进而在区域上作出推断的纯定性传统沉积相分析方法已经不适应当今油气勘探的要求，因此，如何充分利用地质、测井、地震及其他方法提供的大量信息，用综合化、程序化乃至定量化的方法进行盆地沉积相分析和其他研究近年来受到石油地质学家们的普遍关注。

If it is exclusive breastfeeding, nursing mothers can serve calcium, milk-fed babies have a calcium deficiency symptoms should calcium agents, such as calcium gluconate, milk half an hour after feeding, a sub-fed two or three times better absorption and also cod liver oil should continue to serve on weekdays Rideau sun 9:00 choose a more moderate after the sunlight, as much skin exposed limbs, to the best of direct sun to sun, the sun through the window glass was not effective, it should also be noted, In addition, when the sun of the need to protect your baby's eyes, not straight into the sun.

如果是纯母乳喂养，乳母可以服钙剂，奶粉喂养的宝宝有缺钙的症状就要补钙剂，比如葡萄糖酸钙，奶后半小时喂，一支分两三次喂吸收较好，另外还要继续服鱼肝油，平日里多晒太阳，选择上午9点后比较温和的阳光，尽量多露出四肢的皮肤，要直接晒到太阳最好，透过窗户玻璃的阳光没有效果，这点要注意，另外晒太阳时注意保护宝宝的眼睛，不能直对着阳光。

The speculations of the last century concerning mankind in a state of nature, are not unfairly summed up in the doctrine that "in the primitive society property was nothing, and obligation everything;" and it will now be seen that, if the proposition were revered, it would be nearer the reality.

在上一世纪中，有关人类在自然状态中的各种纯理论被概括为这样一个学理，即&在原始社会中财产是不当什么的，被重视的只有债务&，这并非是完全不适当的；但现在可以看到，如果把这个命题颠倒过来，可能会更接近于实际。

Itpossesses the following three characteristics:Thoroughness,based on pure"Ontology",which is characterized by non-objective thought and non-anthropological horizon,it bothexternally and internally transcends modernity;Constructiveness,the task of transcendingmodernity is not to advocate destructive post-modernity,which is in the condition of puretexts,like vacuum,but to re-construct lively"pre-modernity";Actuality,the practicality of thechannels of saving modernity——"thinking"and"poetizing"——determines the actuality ofhis critique.

此种批判具有三个特点：一、彻底性，即非表象性的思维与超人类中心主义的视域所构建的纯&存在&论外在而又内在地彻底超越了现代性；二、建设性，即超越现代性的后果不是倡导纯然破坏性、文本化的后现代性，而是在回归中重建积极的、活生生的&前现代性&；三、现实性，即拯救现代性、回归&前现代性&的途径——&诗意之思&、&思性的诗&——是实实在在地为人所秉有、运作与实现，这决定了他的批判蕴涵有深厚的现实意义。

But, the combination of the pragmatism and the post-colony world is eating the conscience of the art. The narrow twisted and unbalanced folk culture definitely gives birth of a strange baby of the culture; it uglifies the modern art that represents the voice of the modern time. Neither does it brings the Chinese good wishes to a bright future, nor does it lead the Chinese modern art to a brilliant future, yet, it does pushes the clean world into an endless dark world.

然而，艺术领域的实用主义与后殖民的结合，蚕食着了艺术的良知；江湖文化的狭窄、扭曲和失衡，必然催生一种文化的怪胎，因而使得作为时代心声的当代艺术丑陋不堪、问题多多，它既没有把中国人的美好意愿引向光明，也不可能使中国的当代艺术走向辉煌，而是，将一个至纯之地推向一个遥遥无期的晦暗之境。

The method of extending Huffman code-based XML storage and query implements the storing and querying of node information and the information betweens nodes.

对XML数据库系统的研究主要有两个基本途径：纯XML数据库系统，优点是充分考虑XML数据的特点，以一种自然的方式来处理XML数据，能较好地支持XML的存储和查询，但目前技术仍不成熟；在原关系数据库系统或面向对象数据库基础之上扩充

An absolutely pure crystal of salt could have the position of every atom specified by something like 10 bits of information.

一粒纯晶体盐中原子的位置可以说是由10位信息的规则所规定的，这就不会让大脑的信息负荷能力感到吃力了。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.

万寿菊对土壤要求不严，以肥沃。排水良好的砂质壤土为好。

He unstepped the mast and furled the sail and tied it.

他拔下桅杆，把帆卷起，系住。
