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。

In the course of the impulse through underground mediator, because the physical property and the geometric property of mediator is non-uniform, wave form and wave amplitude will change very much and the impulse after shock、antenna direction figure、the couple degree of ground surface、system interfere、non-uniform of the underground mediator、reflection surface's rough cause the disturb of radiation scatter and diffract will complex the figure .

脉冲在通过地下介质的过程中，由于介质的物性和几何性质的不均一性，波形和波幅将发生较大的变化，而脉冲余振、天线方向图形、天线的地表偶合程度、系统内部的干扰、地下介质的不均匀、反射面不光滑等引起的辐射效率、散射的变化以及剖面旁侧的绕射等干扰，均使实时记录图像复杂化。

The results show that molecules of PEO〓 have priority to locate at the interface of PVF〓/PVC to reforce their interaction when content of PEOx was less than saturated concentration in the interface , and PEOx joined into the PVF〓 phase and /or the PVC phase; the particles size of dispersed phase, PVC, became larger when C was more than Cs; the blend became miscible when C was much more than Cs.

结果表明，aPS与sPS的非晶区相容，共混物中不存在aPS的独立相区；共混物的熔点及长周期不随共混物aPS含量的变化而有所改变；sPS的纤晶结构单元没有变化，共混物结晶度下降，aPS处于sPS的纤晶之间；sPS为α-晶型，其晶胞结构参数在共混前后不变，aPS没有进入到sPS的晶胞中。

In infarction patients group,DTI can early detect some small infarction lesions in white matter. With the pathophysiological evolution of the disease, FA and ADCAV changes regularly. In hyper-acute stroke, FA of lesions have no consistent change, appreciably elevated or decreased. In acute, sub-acute and chronic stages of cerebral infarction, FA of lesions unrecovered declined.
