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。

The results suggested that compared with A-starch and maize starch, there are more quantities of impurities, such as protein, lipid and pentosan, in B-starch. B-starch prepared in the laboratory almost has the same compositions as three samplings, and accords with the reports of some documents too. Differing from the granules in A-starch, those in B-starch are smaller sized (1-10m)and oval shaped, and felted each other. The crystallogram of A- and B-starch are similar, i.e. A type. There is difference in granular distribution between A- and B-starch. The granular distribution of B-starch is anomalous and extensive (l~1259m).B-starch has bigger dilatancy and retrogradation, and smaller blue value, solubility, viscosity, gelatinization temperature and gelatinization enthalpy.

试验结果表明：跟玉米淀粉、A淀粉相比较，B淀粉含有的蛋白质、脂肪和戊聚糖等杂质数量多；实验室制备的小麦B淀粉中淀粉、粗蛋白、戊聚糖等含量均与文献的报道接近，也与在工厂采样的B淀粉相近；与A淀粉不同，B淀粉以小颗粒的淀粉为主，平均粒径1～10μm，颗粒形状呈椭圆形，同时颗粒和颗粒之间黏结紧密；B淀粉和A淀粉晶形结构相似，都为A型；B淀粉的粒度分布情况不同于A淀粉，其粒度分布规律性不强，分布范围也较宽，粒度在1～1259μm之间；B淀粉的凝沉值和膨润力大于A淀粉，而沉降体积、蓝值、溶解度、粘度、糊透光度、相变温度和热焓均小于A淀粉；杂质的含量对B淀粉性质的影响是明显的，随着杂质含量的增加，沉降体积、溶解度和透光度减小，膨润力增大，但是它们对凝沉值、蓝值和粘度的影响比较复杂。

Two cases were isointense or hypointense signal on T1WI and heterogeneous hyperintense signal on T2WI and T2WI STIR. Conclusion Enhanced CT clearly showed calcification and blood supply of the tumor while MRI showed small hemorrhage, cystis foci, necrosis and central stellate scar of the tumor. MRI can provide more useful information in detecting chromophobe cell renal carcinoma.

结论肾脏嫌色细胞癌属少血供肿瘤，CT能清晰显示肿瘤内钙化灶和血供情况，而MRI容易检出肿瘤内小出血灶、囊变坏死灶以及中央星状瘢痕，可对肾脏嫌色细胞癌的诊断提供更多更有价值的信息。

The Pr value of a website distributings is such: Generally speaking, the Pr value of website home page is highest, next the numerical value of Pr is met as website navigation or of the administrative levels of catalog deepen and decrescent.

一个网站的pr值分布是这样的：一般来说，网站首页的pr值最高，然后pr的数值会随着网站导航或者目录的层次的加深而变小。

In the meantime, the distance of the insulation layer because of CMOS transistor greatly decrescent, the threshold value that reduce will under 1V, that is meant, IC is increased greatly by the probability of interference, and supply current can become hundreds of dimensions, it is to comparative really of be astonished person.

同时，因为CMOS晶体管的绝缘层的距离大大变小，降低的阈值将会低于1V，那就象征着，IC受到干扰的概率大大增添，而供电电流会成几百安培的规模，简直是相当骇人的。
