Calculating results show that variation of the propellant inlet pressure makes little impact on engine performance parameters, and the engine will transit to a new stable state. The parameter transition curves are smooth. When the engine thrust is adjusted in a small range within a short period, the parameter transition curves are also reposeful. But when the adjusting range becomes large, the parameter transition curves will fluctuate acutely. Thus, when large range adjusting is required, the time of adjusting should be lengthened or the adjusting should be divided into adequate steps.

计算结果表明，当发动机在某一个稳定工况工作时，发动机入口推进剂压强的变化对发动机性能参数的影响不大，发动机的参数都能比较平稳的过渡到一个新的稳定工况；当发动机在短时间内进行小范围的推力调节时，发动机参数的过渡过程的曲线也比较平稳，但是当在短时间内进行大范围推力调节时，参数的过渡过程的曲线振动比较剧烈，因此应当在进行大范围推力调节时，应当对调节时间进行适当延长，或者分级进行推力调节。

On comparing with the common type 4, there are 18 genes presenting change in the rest 21 types, most of them are tRNA genes, and gene replacement, gene increase and gene absence are frequently happened; on the contrary, protein genes are more steady, gene change is mostly of gene replacement. The genome size of Gymnophiona are all smaller than 18000 bps and most of them range from 15000 to 16000 bps, those of Urodela and Anura are bigger than 16000 bps, most of Urodela range from 16000 to 17000 bps, most of Anura range from 17000 to 18000 bps.

For example, to CaSiO〓, wallastonite and cyclowallastonite could be found simultaneously in glazes between the temperature range of 1125℃±10℃, only wallastonite came out below the range, and only cyclowallastonite appeared above the range. Similarly, melilite structure and clinopyroxene structure connected with crystallization temperature. Usually, higher crystallization temperature contributes to forming melilite with simple structure and lower crystallization temperature contributes to clinopyroxene with complex structure.

如钙的偏硅酸盐，硅灰石、环硅灰石的转变温度区域为1125℃±10℃，组分适当的特定釉熔体，高于此温度出现环硅灰石，低于此温度出现硅灰石晶体结构；同样的，黄长石、辉石的出现也与温度有密切的联系，通常，晶体生长的温度较高有利于晶体结构简单的黄长石出现，晶体生长时温度较低有利于稍复杂的辉石结构的出现。

In the Cryptocarya community, the reason for Cryptocarya concinna having high relative frequency and relative abundance is probably not it has wider range of resistance to soil variables but the range of its resistance has much wider spread in broad-leaf forest habitat, or it may just has a wider range of resistance to the limiting factor.

在厚壳桂群落，黄果厚壳桂之所以具有较高分布频度与多度，并非它对所有土壤因子具有较宽的容忍性，而可能是它能容忍的范围在阔叶林生境有较广的分布，或它仅对极限因子的容忍有较广的范围。

Firstly, dicyclopentyldichlorosilane, a reaction intermediate, was prepared under the optimal conditions of a reaction pressure range of 1.0-1.2 MPa, a n/n of 1.16, a reaction temperature range of 85-95℃, a catalyst dosage of 1.2 g, an isooctyl alcohol dosage of 2.3 g and a reaction time range of 6-7 h.

In the paper only the range of normal value and the description of frequency distribution are discussed. In theory the widely-used percentile method to determine the range of normal value is imperfected. Curve fitting method show some advantage in determining the range of normal value, but is difficult to calculate.

从理论上说明了现在常用的确定正常值范围的方法存在一定的问题，尤其证明了大家使用得比较多的百分位数法存在的缺陷，说明了曲线拟合法的优点，而在频数分布拟合完成之后，就已经找到了频数分布资料的理论分布曲线，有了理论分布函数，我们利用分布函数计算正常值范围就比较容易，也比较准确。

The results indicated that the effect of pH on adsorption of theanine was not obvious within range of 6~11. The adsorption date fit well into the Freundlich and Langmuir isotherm equation within temperature range of 303~323 K and investigative concentration range. The isosteric enthalpy of adsorption, free energy and entropy of adsorption showed that adsorption of theanine was endothermic and spontaneous.

The treatment of car-washing wastewater by using membrane bioreactor was investigated. The influences of operating pressure and environmental factors on the membrane's filtration function were analyzed combining with theoretical calculations. In the meiobar range, membrane resistance was the dominant role, independent of operating terms. In the middle pressure range, concentration difference-polarized resistance was the dominant role, depending much on operating terms. In the high pressure range, gelatin resistance was the dominant role. The influences of the operating pressure was small on the membrane flux, and the membrane's separating characteristics were related much with mud concentration, membrane flow velocity and etc.

通过膜生物反应器处理某车辆厂洗车废水的实验研究，结合理论计算，分析了操作压力及环境因素对膜过滤性能的影响研究结果表明，在低压区，膜本身阻力占主导地位，它与操作条件无关；在中压区，浓差极化阻力占主导地位，它与其他操作条件关系密切；在高压区，凝胶层阻力占主导地位，操作压力增加对膜通量影响不大，在此阶段膜分离特性还与污泥浓度、膜面流速等操作条件有关。
