The reliability of analysis result depends largely on the in-house experimental conditions. Unlike the previous analysis that only concerns the sole effect of permeable pressure, this article considers both permeable and confining pressure and deformation characteristics of concrete material under the interaction of them according to the real work state of construction, which may leads to the changing pattern of permeable rate as listed below: permeable rate always reaches its peak with the time process going on, than goes down and remains straight on some certain value; The PR will tend to decline while the confining pressure is increased, and the time taken before the peak will be extended as well; Under the constant permeable pressure and circularly changing confining pressure, the minus-exponential ascend and descend relationship could be applied between the PR and Time axes respectively with crannied and intact concrete samples, and the PR of crannied concrete is far more larger than that of intact concrete. The change pattern of concrete could also be mathematically analogized using the least square method.

室内的实验条件是研究成果可靠性的重要因素，而以往的研究都只考虑了渗透压单一作用，本文根据混凝土结构的实际工作状态，同时考虑了围压与渗透压共同作用下的混凝土材料的渗透性变化特征，得出了混凝土材料在围压作用与渗透压共同作用下的渗透率的变化规律：渗透率都是随时间推移先达到一个峰值，再降低并趋于平稳；渗透率会随围压的增大而减小，并且峰值的到达时间也会随之延长；在渗透压不变，围压升降循环的情况下，有裂缝、无裂缝混凝土的渗透率变化规律是随时间成负指数关系上升、下降，且有裂缝混凝土试件的渗透率远远高于无裂缝混凝土的渗透率，并对混凝土的变化规律运用最小二乘法进行数学拟合。

Observation of radar and intensive surface wind of 0505 typhoon Haitang is used to analyze the relationship between radar reflectivity and observed precipitation and the relationship between mesoscale surface stream field and heavy rainfall. The analysis shows that when the Doppler radar reflectivity reaches 50 dbz, it has a good correspondence to the heavy one hour precipitation. Besides, heavy precipitation is also related to the mesoscale cyclonical current and confluent currents, it occurs near the mesoscale cyclonical or confluent current appearing at the same time.

利用严重影响浙江东南地区的2005年05号台风的雷达和地面加密风场资料，分析对比台风中尺度暴雨过程中雷达回波与实况降水、中尺度地面流场与暴雨之间的关系，结果得到：多普勒雷达近地面强回波带或中心往往达到50 dbz时，与一小时的强降水区有很好的对应关系，暴雨中心区也与地面加密的中尺度流场中出现的中尺度气旋性环流和汇合气流有关，强暴雨区落在同时刻中尺度涡旋或汇合线附近。
