溶液中NH4+的加入，在高 pH值条件下，存在钻氨的络合反应和钻的沉淀反应，草酸钻仍保持针状形貌：在低pH值条件下，随着NH4十加入量的增多，草酸钻形貌变得粗短，长径比、粒度减小；最后呈方形，松装比重增加。

The result shows that the vesicle diameter first increase and then decrease with the increase of AOT mole fraction, the change regularity of which is the same with the depth of apparent blue color. The vesicle size increases with the increase of total surfactant concentration at any mixing ratio.

新制备的PTA／SDS=3／7，总浓度为0.01M的样品，负染色透射电镜观测发现了管状和球状结构的囊泡，球状囊泡的粒径在50～200nm之间，管状囊泡结构直径在70～200nm之间，而长度大约为7000nm，但是类似的"管子"在新制备溶液中还是比较少。

Brownian movement and the hydraulic condition required is only that the coagulant can be dispersed in the water rapidly; As the floe is growing frier, the condition of making the floe diameters controlled in a certain limit is to be provided as well as the condition favorable for the collision of the floe.

得到细小粒子的凝集动力由布朗运动决定，此阶段只需要有将混凝剂迅速分散于水中的水力条件；在絮体进一步成长过程中除造成有利于絮体碰撞的水力条件外，还要造成絮体粒径控制在某一限度之内的水力条件。

The effects of reaction time, concentration,temperature and the characters of the liquid crystal system have...

控制液晶体系中反应物的浓度、含量以及反应时间可得到不同大小的 Ag纳米颗粒。所形成的 Ag纳米颗粒的平均粒径一般小于 10 nm。

The effect of hole diameter change on sound logging data should not be neglected in sound logging .

在声波测井中，井径的变化对声波测井数据的影响是不能忽略的。

By comparing the electrodeposition rate and the particlesize of nanometer Ag film prepared by methyl sulfonic acid silver system with those of nanometer Ag film prepared by nitrate silver system under the same conditions, it is found that the particlesize of nanometer Ag film electrodeposited with nitrate silver is smaller and the growth rate of the nitrate silver nanometer film is faster. During the experiment, the silver grain was smaller and the distribution was more uniform in the nitrate silver electrolyte than in the methylsulfic silver electrolyte.

通过对甲磺酸银体系和硝酸银体系中纳米银膜的电沉积速率及纳米银膜颗粒进行比较发现，相同条件下硝酸银体系得到的纳米膜晶粒粒径比较小，膜的生长速率较快。

The authors determined glutenin protein,soluble in acid glutenin protein, surplus protein content in 21 species of wheat and indexes of rheological characteristics and made sedimentation and bread baking test. By using stepwise regression and path analysis methods,it was further proved that prediction of bread baking quality of wheat by Surplus protein content is more precise than that by sedimentaion and approximately equal to that by the score of flour. So the authors suggest that the direct selection of ...

本试验测定了21个小麦品种的几种蛋白含量以及流变学特性指标，作了沉淀试验和面包烘烤试验，借助于逐步回归分析和通径分析方法，进一步验证了用剩余蛋白含量预测小麦烘烤品质与评价值相当，比沉淀值准确的结论，并建议在小麦品质育种及面包烘烤品质分析中，加强对剩余蛋白含量的直接选择。

Aimed at the problem of the salt bed wellbore creep and shrink under the drilling,based on the elasto-plastic mechanics theory and the head creep equation,the new formula of the control wellbore shrink rate was derived with in case of the plane strain and uniform in-situ stress,which was different from the old formula.

针对钻井过程中钻遇的盐层段井眼蠕变缩径问题，利用弹塑性力学理论，蠕变本构方程采用Heard蠕变方程，在平面应变和均匀地应力假设下，推导出控制井眼收缩的钻井液密度新公式，该公式与前人推导的公式不同。

The motion of manganese nodules in the hoist pipe for the deep sea mining was forecasted by the model. By the simulated results, the smaller nodules, the proper hoist flow velocity and the suitable transportation concentration will ensure the safety and efficiency of the hoist system.

利用该数值模型对锰结核粗颗粒在深海采矿扬矿管中运动的预测结果表明，为保证锰结核粗颗粒水力提升扬矿管的安全，应当控制最大颗粒粒径，并采用适中的输送速度和输送浓度。
