One of the most important factors in building high - performance , scalable web applications is the ability to store items , whether data objects , pages , or parts of a page , in memory the initial time they are requested Asp . net asp . net缓存生成高性能、可缩放的web应用程序最重要的因素之一是能够在首次请求项时将这些项存储在内存中,不管它们是数据对象、页还是页的某些部分。
Significant negative correlation was observed between the initial time of runoff incidence , runoff and soil loss under the hedgerow ecosystems and soybean monocropping pattern , with significant positive correlation between runoff and soil loss 在人工模拟降雨条件下,百喜草、黄花菜植物篱笆生态系统水土保持效应在植物篱笆的生长后期更为突出,而且与雨强有显著的正相关关系。
With the development of jth , it also exposes some internal management problems , such as standardization of management , authorization , human resource , financial issues and so on ; they are all difficult management questions faced by enterprise manager at initial time 卜,随打众人沁的成k山逐渐蜒涤出x种问题,如竹卫川儿v化叫题、授权问题、人力资源问题和则刘棚等,这些用以初创企、惭6i !
Moreover , hedgerow ecosystems were effective in controlling water and soil loss in june and august . under simulated rainfall , hemercoallis citrina baroni and p . rotation flligg hedgerow ecosystems had a significant effect on reducing water and soil loss in their later stages of plant growth , and there was a significant positive correlation between the effect on reducing water and soil loss and the rain intensities . moreover , hedgerow ecosystems decreased more soil loss than runoff , and the initial time of runoff incidences could well represent the water and soil conservation effects of hedgerow ecosystems Rotatumflligg )植物篱笆生态系统年径流量、年侵蚀量分别减少10 . 14 11 . 56倍和135 . 34 165 . 84倍;植物篱笆生态系统和大豆单作处理的径流量、侵蚀量、可产生侵蚀的降雨量之间呈极显著正相关,建立了相应的降雨产流、降雨产沙、径流侵蚀模型,通过侵蚀雨量可以了解水土流失的发生特征; 6月和8月份(多短时暴雨)水土保持能力较明显。
The assimilation experimentation results indicate that after assimilating radar wind field of small spatial scale , mesoscale and small - scale precipitation prediction can be improved and mesoscale and small - scale information which ca n ' t appear by tradition datum can be gained , which is valuable to analyze the mesoscale and small - scale system structure ; the effect assimilating radar humidity field is n ' t obvious , which is perhaps correlation with precipitation types and assimilating time . the results also show that adding radar humidity field to initial condition at initial time can supply the gap of the regular data in reflecting the mesoscale and small - scale systems , strengthen the humidity in the initial field , and eventually help to improve precipitation . the experiment of assimilating radar wind field and radar humility field at the same time shows that vapor transportation and local vapor divergence play more significant role in causing excessively heavy rain than only high wet center 同化试验结果表明:同化空间分辨率很高的雷达风场后,能改善中小尺度降水的预报效果,并且能够得到常规观测资料所不能得到的中小尺度信息,对分析中小尺度系统结构具有重要意义;同化雷达湿度场效果不明显,可能与降水类型和同化时刻有关;而直接在初始时刻加入雷达湿度场,补充了常规资料在反映中小尺度系统方面的不足,增强了初始场中的水汽,有利于降水量的增加;同时同化雷达风场和雷达湿度场的试验表明,水汽的输送和局地的水汽辐合对于产生特大暴雨的贡献远大于仅有高湿中心的贡献。
