雨量

It had strong washing action on cereal aphides and predators above moderate rain, and the larger the rainfall, the greater the scour rate.

结论］中等以上雨量对麦蚜与捕食性天敌有较强的冲刷作用，雨量越大，冲刷率越大。

And there are obvious difference of stemflow among different species, the main factors that affect the stemflow are crown structure, diameter breast-high and crown width.

林内透雨量与降雨量也存在极显著的线性关系。6种森林类型的林内透雨量从大到小依次为灌草地、马尾松林、柏木林、针阔混交林、阔叶林和针叶混交林。

This low carbonate event may have resulted from changes of rainfall. During deglaciation, the dry climate caused a decrease in terrigenous sediment input. However, during Early-Middle Holocene, the rainfall, especially the heavy rain with higher erosions increased rapidly, leading to the increase of terrigenous sedimental supplies from South China mainland and Hainan islands.

在冰消期，出现干旱，陆源物质减少，而早中全新世的雨量，尤其是具较强冲刷能力的大雨量急剧增加，造成北部海南岛和华南陆地的冲刷增强，陆源物质供给增加，从而出现低钙事件。

The QPF results, before and after the mean-field bias adjustment using a multiplicative factor determined based on radar–rain gauge comparisons of the last hour, were compared using rain gauges.

用外推开始前1小时的雷达1小时累积降水和雨量计测值计算平均校准因子，对外推得到的雨量场进行校准后，可以明显提高外推1小时流域面雨量的精度，对外推2小时流域面雨量的精度也有所提高。

The QPF results, before and after the mean-field bias adjustment using a multiplicative factor determined based on radar–rain gauge comparisons of the last hour, were compared using rain gauges. Results show that the QPF results after the adjustment were better than the QPF results before the adjustment.

用外推开始前1小时的雷达1小时累积降水和雨量计测值计算平均校准因子，对外推得到的雨量场进行校准后，可以明显提高外推1小时流域面雨量的精度，对外推2小时流域面雨量的精度也有所提高。

The impact of rain gauge measurements is to increase the precipitation estimated from satellite data. The main difference is in Taiwan and the southeastern China where satellite retrieval underestimates the precipitation rate during boreal spring and summer. For the different precipitation climate analyses, the Legates- Willmot rainfall climate analysis produces the largest annual mean regional rainfall.

微波放射的雨量反演比微波散射法所估计的雨量略高，增加了测站雨量计分析的综合估计，使得区域平均年降雨量比只用卫星资料的估计大，而主要的差异是源自於春、夏季以及台湾与大陆东南沿海地区，显示卫星资料低估区域的锋面降雨。

Thirdly, the rain gauge observations and QPE/QPF mean areal precipitation derived from radar were used for runoff simulation and forecast using a semi-distributed rainfall-runoff model for Xianghongdian and Foziling subcatchments, as well as several watersheds subdivided from Foziling.

用加密地面雨量计网测得的面雨量和雷达—雨量计联合测量降水或外推的面雨量作为TOPMODEL水文模型的降水输入进行了两个水库所控制的流域及其中一些子流域的流量模拟和预报研究。

The seasonal rainfall distribution is uneven, with 78% of the rainfall concentrated in the 5-10, of which 7-9% of the annual rainfall is 47% of the rainfall, and when there is heavy rain.

降水的季节分配也极不均匀，有78%的雨量集中在5～10月，其中7～9月的雨量即占全年雨量的47%，且时有暴雨出现。

Identifying models both for raingauged and ungauged areas were constructed respectively at the confidence level of 95% with respect to the conditions of Beijing mountaineous areas. For the risk zones with raingauges, alarm and recession critical rainfall intensity was determined by forecasting model map of effective rainfall magnitude and intensity.

根据北京山区的实际情况，在确保有一定的预测精度，其可靠性为95％以上的条件下，分别建立其有雨量站和无雨量站的判别模型，即有雨量观测站的危险区可应用实效雨量与雨强的预报模型图，依据实效雨量确定警戒和避难的雨强临界值，由此采取相应措施。

A new method of tracing precipitation isoline is introduced in term of the character of rain spot and isoline.

摘要针对雨量站点及等雨量线的特征，讨论了一种新的等雨量线追踪途径。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
