For the area of low precipitation and comparatively high evaporation capacity annually, surface spraying and evaporating is one of more effective processes to treat landfill leachate. 对年降雨量少、蒸发量相对较大的地区,回喷蒸发处理垃圾渗滤液是一种较为有效的方法。
The higher morbidity of pneumonia was related to low air temperature, high air pressure, low precipitation, low humidity and high wind velocity. 儿童肺炎发病多于低气温、高气压、降水量少、低湿度、风速偏高的气象条件下发生。
Global warming, low precipitation and strong evaporation, frequent strong winds, erosion of freezing and thawing are the dynamic stimulation. 全球变暖,降水量低且蒸发强烈,大风频繁、强劲且持续时间长,冻融侵蚀强烈是草地退化的动力条件;
According to the thought that the main factor of drought is the durative low precipitation and high temperature, we design the Drought Trend Monitoring Index to investigate the daytime precipitation and the highest temperature in summer in Jiangxi province. 根据造成干旱的主要气象因素是降水持续偏少、气温偏高、蒸发量大的思路,利用逐日降水量和逐日最高气温资料进行实验研究,设计了夏季干旱的逐日动态监测指数。
When it is used to analyze data, this model could not only accurately identify years with abnormally high precipitation as well as low precipitation, but also can make accurate independent prediction for the 2002-2004 samples. 通过对该模型的预报检验分析发现,该预报模型不仅能准确地报出历史样本的异常多雨和异常少雨年,并且对2002~2004年的独立样本预报也全部正确。
