降水量

A study o multivariate analysis method of modern statistics was made by using the data of average mont hly precipitation of 24 stations over China.

摘 要：以遍及我国的24个台站1951～1991年41年的月平均降水量为实例，对现代统计学中的一种特殊的多元分析方法进行了分析和研究。

And the precipitation Variations in ECN oscillate for 20-30 years.

并且东部降水量的年代际变化明显，有20-30年周期。

One analysis of 1900-1998 data pegged the increase in precipitation at 2 percent over the century.

1900~1998年的一份数据证实，二十世纪的降水量增加了2%。

The main spatial and temporal distribution features of pentad precipitation in rainy season from 1991 to 2000 over Yunnan Province (84 stations) are analyzed by means of the principal component analysis method. The features of lowfrequency fluctuation are analyzed by the noninteger technique of power spectrum. The relation between lowfrequency fluctuation and El Nino and precipitation in rainy reason of Yunnan Province are studied.

应用主分量方法分析了云南省84站1991～2000年雨季(5～10月)逐候降水量的主要时空特征，并用非整波技术分析了所提取的第1，第2主分量频谱分布的低频振荡特点，同时分析了低频振荡现象与El Nino事件及云南雨季降水多，少之间的关系。

The region in the altitude f rom 4400 to 4600 meters , which is mainly covered by alpine meadow and alpine swamp meadow , is st rongly degraded by the stock raising with it s influence radius of about 24 kilometers. The influence distance perpendicular to roads is also 24 kilometers , since road const ruction accelerates human2induced destruction to vegetation. Vegetation in shade aspect is rising due to the increase in precipitation , while vegetation in sunny aspect tends to be stable or degraded because of the enhancement in sunlight . Furthermore , the vegetation coverage is influenced by the groundwater level . In near riverbed fields , where the depth of groundwater is shallow , plant s can easily grow ; while in far riverbed fields , vegetation is prone to degrade due to drainage. The radius of river influence is 24 kilometers.

海拔4400～4600m的较低海拔地带退化最强烈，主要为高寒草甸与高寒沼泽草甸受牧业影响较大；牧业影响半径为24km；道路的影响范围为24km，道路的修建加速了人类对高原植被的破坏作用；阳坡植被呈现趋于稳定和退化的趋势，阴坡植被表现为增长的趋势，降水量增加是源区植被，尤其是阴坡植被变好的重要原因，而太阳光照增强是导致阳坡干旱和植被趋于退化的潜在原因；近河床区地下水位埋深较浅，植被生长具有稳定的地下水源；在远离河床的一定区域内，地下水易于疏干，植被易于退化，河流影响范围为24km。

The cline is considered the probable result of geographic trends in precipitation, temperature, and perhaps also photoperiod

人们认为这种梯度变异可能是降水量，温度也许还有光周期等地理趋势造成的结果。

Floor of entire county total ground accumulates 4885 square kilometer, climate characteristic is spring dry sand blown by wind is much, the summer is short rainfall is little, year average air temperature 2.5 ℃, fall 350mm is controlled, frost-free period is controlled 110 days, it is typical dry farming county, long-term since, because the ploughshare type of follow tradition plows cultivation, a large number of the earth's surface are completely bare, monsoon comes, soil land of medium fine sanded face is reached organic blow character, cause edaphic sand to change, fertility drops, raise of sand and dust, year answer a year, change dene serious with each passing day, cause aggravation of zoology environment year after year, the agriculture that also decided place produces a condition, groundwater source is not worth badly, 10 years of 9 drought, extensive cultivation, crop yield is low and flabby.

全县总土地面积4885平方公里，气候特色为春季干燥风沙多，夏季短促降雨少，年平均气温2.5℃，降水量350mm左右，无霜期110天左右，是典型的旱作农业县，长期以来，由于沿袭传统的铧式犁耕作，大量地表完全裸露，季风来临，将土壤中的细沙面土及有机质刮走，造成土壤沙化、肥力下降，沙尘扬起，年复一年，沙化日趋严重，造成生态环境逐年恶化，也决定了当地的农业生产条件，地下水源严重不足，十年九旱，广种薄收，作物产量低而不稳。

Based on analyzing the causes of flood and the relationship between variation rate of sunspot and precipitation, the point of view of energy variation continuity is put forward, and it is used to analyze the energy process related to precipitation.

基于对洪水发生原因以及太阳黑子变化率与降水量关系的分析结果，初步提出了从某一地区能量以及能量连续变化的观点，来分析与降水有关的能量过程。

Atmospheric precipitable water vapor is one of the most important parameter to Li model.

在Li模式中有一个重要的输入参数是大气可降水量。

The calculating results show that the precipitable water is well related with the ground water vapor pressure.

计算结果表明，可降水量和相应的地面水汽压之间，存在着良好的数值对应关系。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.

这是凯特，那个是爱朗。
