Based on the Laser Doppler technology, Information technology, Image Recognition and Process tenology, the laser image characteritics of ultra-fine and non-spherical particles are studied. The laser image recognition method based on neural network theory are obtained. The associated hardware and computer software for analysis of the shape characteristics are developed. The shape characteristics of typical particles such as fire smoke particle and carborundum are studied by using such method. The results of this project are useful to develop the new reliable, accurate and rapid experimental diagnoses technology.

The electron is one of the particles.

电子是微粒的一种。

The time correlation function of concentration fluctuation for PSt-DVB having wave vector q is proved to have the form of an exponential decay.

该微粒的浓度涨落时间相关函数在波矢为q时，有指数衰减形式，其衰减速率г=q2Dt。

For the study of Brownian motion established kinetic theory of gases played an important role in the process of .1827, Brown observed that pollen suspended in water such as the random motion of material particles .1877 year, Delta claims that the particles The irregular movement of liquid molecules to its collision-induced .1905 imbalance and later years, Einstein, Langevin Smolukhovski, and they were published on the theory of Brownian motion .1908 year, Perrin Experimental observation of the system, confirmed the correctness of the theory.

对于布朗运动的研究在气体动理论建立的过程中起过重要作用。1827年，布朗观察到悬浮在水中的花粉等物质微粒的无规则运动。1877年，德耳索指出，微粒的不规则运动是液体分子对它的不平衡碰撞引起的。1905年及稍后，爱因斯坦、斯莫卢霍夫斯基和朗之万分别发表了他们关于布朗运动的理论。1908年，佩兰的系统实验观察，证实了上述理论的正确性。

The particle size is as small as one micron.

微粒的尺寸小到1微米。

One of the essential factors of micronization by RESS is that the solubility of the solute in a supercritical fluid should be as big as possible. So it is important to choose a feasible SCF.

RESS法制备超细微粒的关键因素之一是需要微粒化的物质在超临界流体中的溶解度尽可能的大，因此选用合适的超临界流体是非常重要的。

For the following training tutorial, we have used tracks of extraterrestrial particles that were captured in the ODCE collector on the Russian space station Mir, and tracks of submicron dust particles shot into aerogel at 20 km/sec using a Van Der Graaf dust accelerator in Heidelberg, Germany.

在随后的培训指南里，我们使用的轨迹是俄罗斯和平号空间站上的ODCE收集器捕获的地外微粒轨迹，和一些使用德国海德堡&范德夫冈&尘埃加速器以20千米/秒的速度射入气凝胶的亚微米微粒的轨迹。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
