研究表明，对于底部冷却的静态定向结晶过程，两相区低温稀溶液层的存在是形成双扩散对流的原因；双扩散对流的形成与发展造成液相区速度、温度和浓度呈盐指型分布，并促使两相区形成孔道流。

In this paper, in terms of diffusion equation of neutral gas in thermosphere and main ion-chemistry reactions in ionospheric F region, the diffusion processes of H2, H2O and CO2 and ionospheric response to released gases are investigated.

根据中性气体在热层背景中的扩散方程，考虑电离层F区主要的离子化学反应，研究了H2，H2O和CO2气体在电离层高度上的扩散过程和电离层对所释放气体的响应，计算了气辉的体发射系数和发射强度。

Molecular dynamics simulation (NPT ensem2 ble) was used to obtain specific volume as a function of temperature....

随后进行分子动力学模拟得到小分子的运动轨迹，对小分子扩散的两种方式进行了讨论，探讨了侧链对扩散过程的影响。

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 results show that the growth rate of tetrapod ZnO is controlled by spiral growth and its crystallization is via VLS model. The condensation of tiny zinc droplets in zinc vapor is the key factor of the formation of tetrapod ZnO. The growth steps are formed on the terminated faces as zinc diffuses outwards and the elongation of whiskers continues until zinc inside the droplets is depleted. VS crystallization, which has little effect on the elongation growth, takes place on side faces of the whiskers and consequently makes the whiskers radius increase.

结果表明： T-ZnO晶须的结晶作用是气-液-固方式，晶须生长受螺旋生长机理控制；锌蒸气中产生凝聚生长的锌液滴是制备T-ZnO晶须的关键，锌从液滴内向外扩散在晶须的端面产生生长台阶，随着液滴内的原子向外不断扩散，针体部分就不断地伸长生长，当液滴内的原子全部消耗尽时，晶须便不再发生轴向生长；气-固方式的作用主要是促进晶须棱面生长而使晶须变粗，对轴向生长几乎没有影响。

At last, we use the established method to appraise current green technology diffusionl environment of china. The result is that compared with other countries Chinese green technology diffusional environment quality is moderate.

最后应用建立的模糊综合评价方法评价了现阶段中国绿色技术扩散环境，结论是与世界其它国家相比，中国绿色技术扩散环境处于&一般&水平。

After that, the paper puts forward that it is from diffusional environment searching, choosing, spreading and learning green-technology's function to quantificationally appraise environmental quality.

在此基础之上，论文提出从扩散环境对绿色技术的搜寻、选择、传播与学习功能出发定量评价绿色技术扩散环境质量。

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。

When the Point Spread Function associated with motion blur is unknown,estimating parameters of the PSF is necessary for image restoration.

在运动模糊的点扩散函数未知的情况下，估计运动模糊的点扩散函数是运动模糊恢复的前提和关键。

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。
