The results showed that new type structure of organic phase containing inorganic phase between polyimide and titania particle by bond conjunct was formed.The discomposing temperature was decreased with the increasing of TiO2 contents,and the thermal stability was better than polyimide materials under the temperature of 450℃.The pore size increased with the increasing of TiO2 contents,and pore size distribution tended to disperse.The permeability of N2,H2 and CO2 across the membrane were controlled by Knudsen diffusion,and the memebrane exhibited outstanding hydrophilicity since their permeation coefficients of H2O／N,are higher than the Knudsen diffusion values.

结果表明，杂化膜材料形成了有机相包裹无机相的交联结构；聚酰亚胺与二氧化钛粒子形成了新型键联结构；其热分解温度随二氧化钛含量的增加而降低，在 450℃以下热稳定性优于聚酰亚胺膜材料；平均孔径随二氧化钛含量增大而增大，孔径分布趋于弥散；N2、H2和CO2在膜内渗透由Knudsen扩散控制，H2ON2分离因子均大于Knudsen扩散值，表现出良好的亲水性。

The experiments reveal that solvent outflow is controlled by the system's viscosity while non-solvent inflow is controlled by the hydrophile of the interface.

实验表明，溶剂外扩散受控于体系的粘度，非溶剂的向内扩散受控于界面的亲水性。

The connective tissue layer of SZMS is a communication pathway for superficial spread of infection, hematoma, or tumor invasion to or from the scalp and face. Compartments of deep fat pad and temporal muscle are also pathways for the spread of disease to or from the face, intracranium and orbit. The primary tumors in infratemporal fossa and SZMS are rare. Malignant tumors in SZMS usually come from surrounding spaces.

上颧骨咀嚼区的结缔组织是颜面部及头部之感染、血肿、及肿瘤的表浅扩散连结路径，而深层脂肪垫区及颞肌亦是颜面部、颅内及眼窝之病灶的扩散连结路径，原发性下颞窝及上颧骨咀嚼区肿瘤非常少见，恶性上颧骨咀嚼区肿瘤通常来自於附近空间。

XRD and SEM analysises show that the V, Ti and Ni elements interdiffuse between the granules and Ni powders took places, resulting in forming a diffusing interlayer, its thickness increased with raising of the sintering temperature.

经XRD及SEM分析表明，烧结后，V2.46TiFe0.54合金颗粒与Ni粉之间发生了V、Ti、Ni的扩散，形成了扩散中间层，该中间层的厚度随烧结温度的升高而增厚。

Then the model is modified, considering the effects of irregular entrainment interface on the top of IBL, and applied to fumigation dispersion over Nanticoke coastal area.

然后考虑混合层顶不规则夹卷界面的作用，应用于楠蒂科克沿岸陆上熏烟扩散问题，将模拟的地面轴线浓度与观测资料以及三个熏烟扩散预测模式的结果作了比较。

The finding comes from a team of Japanese researchers, who report in the March 4 issue of Nature that the hydrocarbon molecule picene, ordinarily a semiconductor, becomes a potential superconductor when interspersed with an alkali metal such as potassium or rubidium.

这项发现来自于日本研究人员。他们在3月4日《自然》杂志上撰文称，一种叫苉的烃类原本是半导体，但在其中扩散过碱金属后就会变成超导体。扩散钾以后，这种材料的临界温度是相对&暖和&的18K（-255℃）。

Finally, the article discussed the possible mechanism of multi-phase electrochemical degradation of wastewater through the XPS spectrum of the used catalysts surface: In the acid solutions, the electro-generated O_2 may get electrons on the porous graphite cathode and then form H_2O_2, H_2O_2 may diffused to the surface of catalyst and reacted with its active part to produce OH, which in turn can destruct organics. The catalyst functioned as both the catalyst to decompose H_2O_2 and the flocculants to sedimentate the degraded waste.

最后全文结合研究反应后催化剂表面的XPS光电子能谱推断了该体系降解污废水可能的反应机理：在酸性条件下，石墨双阳极产生的O_2被多孔扩散性石墨阴极还原成H_2O_2，并通过扩散传质作用在催化剂的表面活性中心分解为强氧化性中间产物·OH，强氧化性攻击有机物，使其降解为小分子有机物或CO_2和H_2O，催化剂在体系中即起催化作用也起吸附、絮凝作用。

The inhibition mechanism of MoO42- was that MoO42- transformed the hydrate ferrous oxide deposition film from anions selective to cations selective,and the cathodic process of underscale local corrosion was suppressed when it migrated into OCC.Meanwhile, the migrated MoO42- resulted in increasing the impedance of the film on the substrate metal and so inhibited the anodic process of the corrosion reaction inside the OCC.

MoO42-的作用机制在于使水合氧化铁腐蚀膜由阴离子选择性变为阳离子选择性，H+可以从膜下扩散出去，而Cl-难以扩散到膜下富集，抑制了腐蚀反应的阴极过程；同时MoO42-迁入闭塞区后增大了电极表面膜层阻抗，抑制了腐蚀反应的阳极过程。
