吐鲁番盆地的大降水具有降水时间短、强度大、范围小，雨量集中等特点，它的发生机制是在高空低槽控制的有利天气形势下，地面动力辐合作用和热力作用触发了大气中的潜在不稳定结构，使得大气有效位能大量释放，形成强烈的对流；同时，有充沛的水汽输入盆地，在有利地形条件下，产生强对流暴雨。

At last,a convergent and general protocol to marine natural product,as demonstrated by the enantioselective total synthesis of malyngamides O,P,Q,R, 5"-epi-Q and 5"-epi-R bearing terminal vinylic chloride structure,was developed in detail.E,(7S)-7-methoxytetradec-4-enoic acid was prepared using the above described Johnson-Clainsen rearrangement,the terminal vinyl chloride was constructed using Wittig reaction as key step,the pyrrolidone derivative was constructed using L-serine as natural chiral pool.Starting from the synthesis of malyngamides O and P to explore the general route,an aldol reaction of methyl acetate with the vinyl chloride part in the presence of LDA gave the skeleton of amine portion,followed by amidation with the fatty acid finished the synthesis of malyngamide P.

先以malyngamides O和P为试点探索通用合成路线，将乙酸甲酯和烯氯部分在LDA存在下进行aldol反应得到氨部分的骨架，再将手性不饱和脂肪酸和氨部分进行酰胺化反应完成了malyngamide P的合成，将P在碱性条件下进行烯醇甲基化反应完成了malyngamide O的全合成。

Distinguishing from the former researches about CR service communication interruption, only spectrum handoff times exceed a certain number, communication interruption will occur. This strategy can reduce the COP of CR services.(3) Some coexistence issues between WRAN and DTV system are studiedFirstly, the network architecture, system parameters, and self-coexistence of Wireless Regional Area Network are investigated, and convergent performances among overlapping Base Station are simulated and validated. Then, a simple coexistent scenario between WRAN and Digital TV is designed to analyze the interference from WRAN BS to DTV receiver.
