扩散的

There exist negative correlations between the ionic porosity, which is a measure of atomic packing density in minerals, and Ar and H diffusion activation energies. Thus ionic porosity can be used to predict element diffusion coefficients.

孔隙度作为矿物内部离子堆积密度的一种量度，它与Ar和H的扩散活化能之间存在负的线性相关性，因而可以用于预测元素在矿物中的扩散系数。

Biodegradation is a dynamic process, where the diffusion of hydrocarbon to oil water contact, the diffusion of metabolites away from the reaction site to the oil column. Late charging and mixing occurred in the reservoir also control on the degree of biodegradation.

生物降解是一个动态过程，烃类不断向油水界面扩散，降解过程中新形成的代谢物从油水界面向油柱扩散，后期充注及油藏内的混合作用也是控制生物降解作用程度的重要因素。

One gauge (3000 PSI max) displays the pressure inside the bottle and the other gauge (60 PSI max) displays the pressure leaving the adjustable regulator.

A thin film of titanium carbide is obtained by vacuum evaporating oftitanium. With diffusion treatment, the existance of titanium carbide is identified by X-raydiffraction analysis. Quantatitive analysis is made by XPS to invetigate diffusion ofcarbon atom between diamond and titanium film.

用真空蒸镀法在金刚石表面镀覆Ti层，并经扩散处理使金刚石表面形成TiC膜，实现了金刚石表面的金属化。X射线衍射分析证实了TiC的存在，利用XPS定量分析验证了在金刚石表面碳原子与钛镀层之间的反应扩散模型。

In this study,we took a measurement of sound pressure distribution, sound field variability, and effects of frequency shift on sound pressure levels at reference points of pure tone in the diffuse sound field.

本文通过对纯音声压分布、声场变异以及频率漂移对参考点声压级影响的研究发现，扩散场中纯音声压分布的均匀性虽不如啭音，但在某些范围其能量仍可充分扩散，这些区域声场测试结果受受试者头位改变和／或频率漂移影响轻微。对20名重度感音神经性耳聋患者的测试结果证实了上述结论。

The increase in the diffusional deposition was found to occur mainly in the chamber after the vane section when the gas expands and slows down. Therefore, particles have longer residence time to be collected in the chamber by diffusion.

此外发现微粒的扩散损失主要发生於导翼片之后的微粒收集腔体中，因为气流出了导翼片之后速度大幅降低，微粒因而有较长的停留时间由於扩散作用而被收集。

Corresponding to the Darcy-Richards equation, hydraulic resistance and resistivity are the reciprocals of conductance and conductivity respectively; time constant is the reciprocal of the diffusivity; and time constant per unit squared length is the reciprocal of diffusivity.

与Darcy-Richards方程相对应，水阻、时间常数分别为导水度、水分扩散度的倒数，相应地单位化的水阻率、比时间常数分别为导水率、水分扩散率的倒数。

Wet stack emission will reduce the lifting height of the flue gas, and it's not beneficial to gas diffusion; the momentum of the flue gas should be guaranteed to decrease the plume downwash and to promote gas diffusion; each of the emission index of the wet flue gas can meet the requirements for the environmental protection.

数值计算与分析表明，湿烟囱排放会增强对烟囱的腐蚀性，需采用特殊的防腐处理；湿烟囱直接排放会降低烟气抬升高度，不利于扩散；为减少烟流下洗，增强扩散，应保证烟气的出口动量；湿烟气各项排放指标能满足环保要求。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
