查询词典 Oort cloud

I suspect these occultation events are going to find Oort Cloud objects sooner.

我认为通过这些'掩星'事件，不久后将可发现奥特云里的物体。

Even though the nebular material was ejectedfrom the star many thousands of years ago, the close-in dust could begenerated by collisions in a reservoir of objects analogous to our ownsolar system's Kuiper Belt or cometary Oort cloud.

虽然星云的物质在几千年前被抛射出去，星球附近的尘埃可能是附近的尘埃盘的碰撞所导致，有点类似於太阳系统的科伊伯带或是奥特云。

"It's an interesting way to look for some sign of the Oort Cloud, which is very hard to do from the Earth," says Renu Malhotra of the University of Arizona in Tucson.

亚利桑那大学图森分校的瑞纽·曼赫塔说：&这是一种查看奥特云的一些迹象的有趣方法，从地球上很难做到这些。&

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。

The results showed that the mixed cloud and stratiform cloud were the main objective cloud,and the operation efficiency of stratiform cloud was the highest(80.5%).

结果表明：聊城市高炮、火箭人工增雨的作业以混合云和层状云为主要目标云系，层状云作业效率最高，可达80.5%。

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。

Discussion (1) Mean temperature variations in China in the last millennium synchronize well with the classical solar minimum, such as the Darton minimum, the Maunder minimum, the Sporer minimum and the Oort minimum, suggesting a strong linkage between temperature variations and solar variability in the last millennium.

综合讨论(1)"红原-金川"平均温度变化趋势显示，近千年中国平均温度变化与经典的太阳活动极小期，如Darton极小、Maunder极小、Sporer极小、Oort极小，等等，表现一致。

By observing the Doppler shifts of stars moving near the galactic plane, Oort was able to calculate how fast the stars were moving.

借助观察靠近银河面的运动恒星多普勒变换，Oort能够计算出恒星移动多快。

If you were not , and OS X just booted normally, have no fear.

如果你没有，和OS X刚刚启动通常，没有恐惧。

I only want to preserve our all .

我只想保存好我们的一切
