查询词典 fluid

The earth is a complicated system, and it has been continuously moving differentiating and evolving since it had been formed. Not only has the earth layering structure, but it has vertical movement of materials. The movement is prompted by the mechanism of force and heat of the centrifugal force to be formed by the rotation and revolution of the earth, and difference of temperature, pressure, density, viscosity and velocity in the between core and mantle, and radioactive heat, et al. The expressive means of the mechanism of force and heat are the precesses of mantle plume and mantle fluid. Not only are ore-materials of core and mantle carried directly into crust, but ore-materials of crust are activated and accumulated into proper location by the mantle fluid having the supercritical nature.

地球是一个复杂的系统，自形成以来，一直处于不停地运动、分异和演化过程；它不仅存在着圈层结构，而且伴随其自转和公转的离心力，以及核幔间的温度差、压力差、密度差、粘度差、速度差和放射性蜕变热等动热机制，同时存在着以地幔柱和地幔流体作用方式的物质垂向运动；这一过程，不仅直接向地壳带入核幔成矿物质，而且通过流体自身的超临界性质，将沿途活化已有初步富集的成矿物质转移至地壳适宜部位集中成矿。

针对现场油基钻井液所钻井出油少、注水困难等问题，评价了油基钻井液滤液、完井液、水泥浆、注入水、地层水间的配伍性，以及油基钻井液滤液、原油对岩心动静污染后吸水能力的影响。

The compound solution performs as pseudo-fictile fluid, and its visual viscosity is reduced when the shearing velocity increases. The higher the cationic degree of CPAM, the more apparent the rarefying behavior of the polymer-surfactant complex, but it still is pseudo-fictile fluid. In addition, such factors as the molecular weight of CPAM, temperature and PH value etc, have different effect on the properties of the mixed solution, including its visual viscosity, conductivity, rheological behavior and so on.

CPAM／SDS复合体系的表观粘度随剪切速率的增大而下降，即具有剪切变稀行为的特性，表现为拟塑性流体：CPAM的阳离子度越高，它与SDS形成复合体系剪切变稀的行为越明显，但体系的流动类型不发生变化，仍为拟塑性；随着CPAM分子量的提高，复合体系的非牛顿性增强；温度的升高将导致复合体系的粘度显著降低，非牛顿性减弱；对于SDS用量低于等电荷当量的复合体系，pH值的变化对其流变性的影响不显著。

In the light of serious corrosion of tubing and casing in Jianghan oil field at present,three kinds of material(N80,J55 and P110) was selected as objects to study the four kinds of flow media such as mud fluid normal acidification fluid,reinjected waste water and injected clear water used in the key stages of the development in oil field in the laboratory.

针对江汉油田油套管腐蚀比较严重的现状，实验选择3种材质(N80、J55、P110)作为研究对象，对油田开发中的几个关键阶段所用到的4种流动介质，如钻井泥浆液、常用酸化液、回注污水、注入清水，综合地进行了油、套管腐蚀室内实验研究。

The discovery of electric repulsion soon led to the introduction of a two-fluid theory that rivalled the one-fluid theory.

电斥力发现后不久，人们即采用了&两种电流质&理论，这种理论与单一电流质理论相抗衡。

When comparing the results of the Fe2+/HPCD flushing through S2O82- fluid sparging curtain system to the S2O82-/HPCD flushing through Fe2+ sparging curtain system, the former system resulted in a higher rate of chloride formation. Therefore, the S2O82-/HPCD flushing through Fe2+ fluid sparging curtain may offer a potential way for remediation of TCE-DNAPL contamination.

相较Fe2+/HPCD淋洗通过曝S2O82-流体帷幕与PS/HPCD淋洗通过曝Fe2+流体帷幕实验结果指出，前一种方式可得较高之Cl-生成率，因此推论於实场应用上，以PS/HPCD淋洗通过曝Fe2+流体帷幕为一具潜力之处理TCE-DNAPL污染之整治方式。

A new PRD spudding fluid was developed, the performance of the PRD weak gelling spudding fluid was evaluated.
