Based on a two-dimention hailstorm model, the numerical simulation of wind shear influence on strong convective cloud precipitaion is carried out using real rawinsonde data as input.

本文用二维冰雹云模式，以实际探空资料作为初始场，对风切变在强对流降水中的影响，进行了数值模拟。

Forecasters say there is no prospect of rain in the next few days.

天气预报称未来几天内不会有降水的迹象。

It may be used to measure the air tempe-rature、 pressure altitude、relative humidity and airspeed.

在人工降水、云物理研究和大气探测中可作为一种基本测量手段。

This work could potentially enforce the related researches in interpolations of precipitation, and even other spatial climatic data.

地统计方法对于预测降水具有重要的价值，而不同的地区具有各自适合的模型，理解该方法的数学原理和操作过程，对相关研究具有借鉴意义。

7 Percent of rain water was kept in plant after 7 days. The change of plant water δD indicated the water use efficiency of plant was effected by micrometeorology factors. The rising of soil temperature prevented plant root absorbing soil water, and soil moisture content facilitated plant root absorbing soil water.

大雨（65.3mm）降水后，雨水能够更快地渗入植物的根系层，对干旱区植物的补水作用较强，植物能够及时利用大雨，而且雨水在植物体内保持的时间较长，7天后植物体内保持雨水的41.8-53.7％。

The relationship between mantle fluid and U ore-forming was studied preliminarily,according to the results,the author considered theΣCO_2 of mineralizer and heat source came from mantle,which is because upwelling mantle forced by crustal extention and deep-seated faulting produced melt blending with lower crust,during this process,mantle provided the heat and releaseΣCO_2 to crust through outgassing.U mainly came from mantle-curst fluid formed by mantle-curst melt blending and the wall rock during fluid uplift.H_2O mainly generated from mantle fluid and the wall rock during mantle fluid uplift,and partly from atmospheric water in the late period of ore-forming.

初步探讨了地幔流体与铀成矿作用的关系，认为矿化剂∑CO_2和热源来源于地幔，是地壳拉张和深大断裂活动导致部分熔融地幔上涌，与下地壳产生壳幔混熔作用，在混熔过程中提供热量和向地壳&去气&释放∑CO_2；U主要来源于壳幔混熔形成的壳幔混合流体和流体上升途经的围岩；H_2O主要来源于地幔流体、地幔流体上升途经的围岩，在成矿晚期有部分来源于大气降水。

Generally over the course of a year, the country only sees 17 millimetres of rain.

一整年，这里也只有17毫米的降水。

The magnitude and duration of a precipitation event determaine the relative importance of each component of the hydrologic cycle during that event .

在这一事件的严重性和降水事件determaine的每个组件的水文循环时间的相对重要性。

Principal Component Analysis and Fuzzy Clustering were used to evaluate the drought tolerance of 16 foxtail millet cultivars based on their performance under the conditions of rainfed and water limited cultivation under rainout shelter.

采用主成分分析(Principal Components Analysis，PCA)和模糊聚类(Fuzzy Clustering，FC)分析，根据16个谷子品种在干旱胁迫和自然降水条件下的抗旱相关性状对其抗旱性进行综合评价。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
