查询词典 diffusion cloud chamber

Diffusion tensor imaging is a kind of new technique after diffusion weighted imaging.DTI can reflect anisotropy hydrone molecular diffusion features of damaged myeloid tissue through measuring apparent diffusion coefficient and fractional anisotropy.Accordingly,we can make more precise and allround estimate about spinal compression on microscopic scale.

Contemporary artificial rainfall is artificial rainfall basically is principle of basis nature rainfall, launch activator from the ground through the plane is spread or using tall artillery piece, rocket, wait like silver iodide, dry ice, liquid nitrogen, drop cloud layer temperature thereby, form supersaturation lunt; to perhaps condense to the boardcast sowing in the cloud layer that contains supersaturation lunt nucleus, increase the ice crystal amount in the cloud, increase the amount of drip-drop and diameter then, raise cloud precipitation change rate, achieve the goal that raises precipitation of bureau ground nature thereby.

二、现代的人工降雨人工降雨主要是依据自然降雨原理，通过飞机播撒或利用高炮、火箭从地面上发射催化剂，如碘化银、干冰、液氮等，从而降低云层温度，形成过饱和水汽；或者向含有过饱和水汽的云层中撒播凝聚核，增加云中的冰晶数量，进而增加雨滴的数量和直径，提高云降水的转化率，从而达到增加局地自然降水的目的。

It is presented that indirect assimilation experiment of CMW data from TCFM method improves effectively not only on vertical velocity field but for precipitation.4 Based on theory analysis, E-Ir relationship is brought forward with two electrification mechanisms. One is inductive mechanism, i.e., cloud particles collide with precipitation particles then flick away, the other is noninductive mechanism because of different temperature, i.e., bigger supercooled cloud particles collide and freeze with hail particles combined with ice scraps. By means of CINRAD and FY2C data assimilation, precipitation intensity Ir can be obtained, then electric field intensity E, discharge time and locations can be achieved with supposed threshold 300KV/m. Though it can not distinguish between IC (Intra-Cloud) lightning and CG (Cloud-to-Ground) lightning, results are still comparable to LLS observations.5 Example analysis shows that the relationship between precipitation data from AMS and CG data from LLS is not very clear.

同化实验对于台风眼区的螺旋形雨带贡献显著，说明TCFM云导风资料同化实验不仅有效调整了模式的垂直速度场，还对降水模拟有了明显改善。4通过理论分析，利用云粒子与极化降水粒子碰撞并弹离的感应起电机制和较大过冷云滴与雹粒碰冻并产生冰屑的温差起电机制下得到的E-Ir，由雷达、卫星遥感资料直接和间接同化模拟得到Ir，来反推E，了解雷暴云中闪电强度的平面分布，设置放电阈值为300KV/m，推算出放电的位置和首次发生闪电的时间。

In each kind of different cloud, its cloud drop size distribution isvarious, creates the cloud drop size uneven reason is in thesurrounding air the water vapor shift as well as cloud dropevaporating.

在各种不同的云内，其云滴大小的分布是各不相同的，造成云滴大小不均的原因就是周围空气中水汽的转移以及云滴的蒸发。

There are some main conclusions as follows:1、 In Inner Mongolia, Mean cloud amount, low cloud amount, middle cloud amount , liquid stratocumulus liquid stratus、 ice stratocumulus、 ice stratus、 ice nimbostratus cloud amount are getting more from west to east.

主要研究结果如下： 1、内蒙古地区总云量、低云量、中云量、液态层积云、液态层云、冰像层积云、冰像层云、冰态雨层云云量呈自西向东依次增多，高云量、卷层云、深对流云云量自西南向东北依次减少的空间分布特征。
