This highlights the excessive nature of the common practice of split applying high rates of ammonium nitrate or urea.

作者指出，适于引起淋失的环境条件加上高降雨量，可能使施用控释氮肥的好处更加明显。

Fungal infection was positively related to temperature and rainfall significantly, but negatively related to aphid density.

结果显示：麦蚜真菌病的发生水平与温度和降雨量成显著的正相关关系，与蚜虫密度成极显著的负相关。

Based on data of Yanhe river basin's hydrological stations on precipitation, runoff, soil and water conservation measure area sizes (terrace land, forestation land, grassed land, and silted dam land) from 1950s'-1980s', the basin's monthly precipitation station weightiness indexes and the four main measure areas weightiness indexes through correlation analysis and factor analysis were built.

以建立一种科学的较简单的评价方法为目的，以延河流域水文站20世纪50-80年代30余年降水、径流、水土保持主体措施面积(梯田、造林、种草、淤堤坝)资料为基础，运用相关分析、因子分析等方法，建立了流域雨量站各月降雨量权重指标体系、流域4大水土保持措施面积权重指标值，并构建了以水土保持面积指标、降雨量指标为参数的流域水文响应评价模型，进而分析水土保持措施对流域径流量的效应。

But Africa's rain falls more variably than, say, Norway's, and its dams often operate below capacity.

但是非洲的降雨量非常不稳定，比方说与挪威的降雨量相比，并且其水坝经常达不到满负荷运转。

The whole situation of high potential North-South low, terrain divided into three parts: the northern high mountains, 30-7300 m above sea level, climate cold, snow and ice covered mountains, sparsely populated, lower slopes have dense forest; Central Valley region, 90-300 m above sea level, mild climate, the annual The average rainfall is 760-200 mm, is the major crop-producing areas of Bhutan; the southern mountain region, hot and humid climate, the annual rainfall of up to 50-60 mm in the mountains dense jungle.

全境地势北高南低，地形分三部分：北部为高山区，海拔30—7300米，气候严寒，山峰覆盖冰雪，人烟稀少，较低的山坡有茂密的森林；中部河谷地区，海拔90—300米，气候温和，年平均降雨量760—200毫米，是不丹主要农作物产区；南部山地区，气候湿热，年降雨量可达50—60毫米，山上丛林密布。

In 2001, in June there was an extensive drought with rainfall just 10% of normal levels, which served to undermine agricultural crops. And then a few months later, in October, there were extensive floodings leading to the further destruction of rice harvests and a crisis situation in food distribution.

2001年六月出现大面积的干旱，其间降雨量只有正常降雨量的10%，这大大破坏了农业系统，几个月之后在十月发生了大面积的洪涝灾害，进一步破坏了农作物的收获，整个食物分配出现了危机。

Based on this,the author applys this model and the adaptive neural networks algorithm to grape plant disease forecasting, and tests the effect of the model through forecasting the degree of grape in Hebei zhuolu county. The work of this article is as follows:(1)Through statistical of the many kinds of grape plant diseases,we get variety of diseases with association analysis under the same conditions occurrence quantity.

本文所做的工作如下：(1)通过对多种葡萄病害猜测资料的统计，进行关联分析得出各种病害在相同条件下的发生量，且得到6个生态和生物因子，按影响程度的大小依次为：六月均匀日照时数、六月降雨量、六月相对湿度、五月均匀日照时数、五月降雨量、五月相对湿度。

Erin could bring heavy rains to a state that already has one of the rainiest summers on record.

Erin可能会给south texas带来强降雨量，成为历史上雨季的最大的降雨量之一。

The joint and conditional frequency of rainfall with different runoffs and runoff with different rainfalls were figured out with this model .

它可以给出不同程度暴雨和径流遭遇组合的频率，也可以在一定的降雨量条件下给出不同径流量的发生频率，或一定的径流量条件下给出不同降雨量的发生频率。

He looked at rainfall data and found 700-800 millimetres fell every year in some parts of the north China plain.

他看了降雨量的数据并且发现了中国北部一些地区的降雨量每年减少700 至800毫米。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
