降雨

We estimated the conditional symmetry instability by absolute and geostrophic momentem and comparative potential temperature.

利用角动量和相当位温对条件性对称不稳定进行定性判断，此次降雨过程的确存在对称不稳定和对流不稳定。

A number of cities in the south had an acid rain frequency exceeding 80%.

一些南方的城市的降雨中超过80%都是酸雨。

The followings are studied in this paper:(1) The orbit is evaluated according to a three-dimensional numerical model of the aerated water jet.

根据掺气水舌入水喷溅特性，建立了水滴在重力、浮力、空气阻力、水舌风及环境风的作用下的水滴随机运动的微分方程，给出了数值计算模型求解降雨强度的计算方法。

In the other hand, the main cause of the craze and deformation of the house of middle-ahead of the landslide is the bank astaticism for the Qu River's water-level rising and dropping at the time of flood season and the local slippage for the rain.

而滑坡体中前部房屋开裂和坡体的变形破坏则主要是由于汛期渠江水位的大幅度升降导致库岸边坡失稳以及降雨诱发坡体局部滑动。

The trials on cultivation of Atriplex canescensconducted in Minqin Desert Control Experiment Station reveals that this speciesentails fine qualities as strong tolerance in drought, cold, salinity and low temperatureas well as high annual biomass. So it cab be extended in sandy areas with favorableirrigation condition, and on hilly in loess plateau with relatively high rainfall and lowevaporation. As a new substitute species for water/soil conservation and rangelandregeneration, it has a big potential to be extended. However, more research on withinwhich scope this species can be extended need to be done

从干旱沙区民勤治沙综合试验站的栽培来看，四翅滨藜在此地表现出了耐旱、耐寒、耐盐碱、耐低温且年生长量大的优良特性，因此可以在有灌溉条件的沙区和降雨较多且蒸发较小的黄土丘陵区进行推广，作为该地区的水土保持和草场更新的新物种，具有一定的推广潜力，但推广地域范围的划分，仍需进一步的试验研究和充分的科学论证。

Attenuation induced by rain is prediceted with the equivalent complex refraction constant. The attenuation predicted is nearly consistent with that calculated by the formula recomended in ITU-R and measured results, which testifies that the method used in that paper is effective.

然后，利用所得公式计算得到的等效复折射指数预测了降雨衰减率，预测值与ITU-R推荐公式计算结果及实测值基本符合，说明文中所使用的方法是有效的。

Rain attenuation is a main factor that affects the communication capability and the quality of transmission in Ka band satellite communication.

降雨衰减是影响Ka波段卫星通信系统传输质量及系统性能的主要因素之一。

The average rain falls 100 times out of 356 days in Beijing.

北京 一年的平均降雨次数为100次。

Then, for a brief time, the desert can be literally carpeted with color. Almost as quickly as they appeared, these small plants die away.

这些小植物很快就消失了，几乎就象它们长出来时那样迅速，但它们已发展了特殊方式来保证在下次降雨来时下一代的生命。

According to simulated result of slope depending on time's changing, we learn that the slope factor of safety will change which depends on rainfall infiltration. Factor of safety of crack slop has much changing than F.S. of flat slop by raining 12 hours to accumulate the rainfall of 100mm.

本研究在边坡安全时变分析之模拟结果显示，边坡之安全系数值会因降雨入渗过程而有所改变，且同样降雨12小时累积雨量100mm情况下，有裂缝坡顶场址安全系数值较平面坡顶场址变化大。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
