The circinal cavities were found in calcium alginate beads and the cylinder holes were observed in zinc alginate beads from the SEM,which indicated that the volume of fraction of zinc alginate polymer was relatively bigger and the zinc alginate polymer chain was more rigid than that of calcium alginate .

凝胶的SEM照片可见，海藻酸钙的冷冻干燥颗粒内为较大的圆孔，海藻酸锌凝胶内为较小的长孔，表明海藻酸锌高分子链在凝胶颗粒中的体积分率相对较大同时刚性较强；卵清蛋白从海藻酸凝胶颗粒中释放的试验结果表明，由于上述海藻酸锌凝胶的特性，导致海藻酸锌对卵清蛋白扩散阻滞作用相对较强；根据试验数据计算得卵清蛋白在海藻酸钙、海藻酸锌凝胶颗粒中的扩散系数分别为1.19×10-7、0.07×10-7cm2/s，利用阻滞模型计算得海藻酸锌高分子链在凝胶颗粒中体积分率约为海藻酸钙高分子链在凝胶颗粒中体积分率的1.7倍。

Consequently, for short exposure time the lower molecular-weight condensable oAMCs may be a more important contamination problem than the higher molecular-weight condensable ones.

此外，利用吸附沈积动力模式计算，将获得晶圆於制程中最大允许浓度或最大可曝露时间建议值，此结果可提供国内半导体相关产业在解决日渐严重oAMCs问题与发展微污染控制技术之参考。

Circular dichroism spectroscopy measurements also reveal that the ordered structure content of α-helical and β-structure of ovalbumin decrease, and the unfolded random structure is enhanced with increasing pressure; While the existence of dextran sulphate to the native ovalbumin, there are no apparent change on the secondary structure of ovalbumin; It seems same to glycinin.

圆二色性光谱分析表明，经超高压处理后，鸡蛋清蛋白分子中规则的二级结构减少，而部分规则的二级结构和无规卷曲含量增加。加入硫酸右旋糖苷的鸡蛋清蛋白溶液经超高压处理后其二级结构中各部分的含量变化不大：对于大豆豆球蛋白，加入硫酸右旋糖苷后，大豆豆球蛋白分子经超高压处理后其有序结构的减少及无规卷曲的增加都相对减缓。

The immunocytochemistry was used to identify the RASMC.RESULTS: The RASMC were successfully cultured by the adherent method of tissue explants and grown in the "peak- valley" mode. The cultured RASMC were fusiform shape with a big oviform or round nuclei rich in cytoplasm. Immunohistochemical method ( S-P method) showed strong expression of a- smooth muscle actin.

结果：组织块贴壁法成功培养出SD大鼠胸主动脉平滑肌细胞，培养的细胞呈典型&峰-谷&样生长，HE染色细胞呈梭形，胞浆丰富，核大而圆或椭圆，免疫组化S-P法检测a-平滑肌肌动蛋白单克隆抗体呈强阳性表达。

At same time, the inverse-trapezium nectar scales, rectangular and spheral seed with high longitudinal ridge were also reported.

The breed has a squarish face, a thick neck, large ears, big, rounded eyes, and a large, muscular body.

品种有squarish脸，厚厚的颈部，大耳朵，大，圆眼睛，和一个大型，肌肉组织。

The first case is the variable depth with a fixed notch-width and the second case is variable width with a fixed notch-depth. It can be observed fromthe moment-curvature curve of the first case that the magnitude of the moment is larger for the deeper depth than that for the shallow depth.

由有限元素ANSYS 分析结果可以观察出，在控制固定曲度做循环弯曲负载时，弯矩－曲度曲线图显示出，在固定凹槽的宽度，当深度较浅时，达到设定的控制曲度所需施加的弯矩相对於凹槽深度较大的圆管要大的多。

The research shows that, when fluidized gas is used only, it had little effect on the quantity of returning solids, and that the effect of loosed gas is significant. Horizontal opening has distinct effect on the circulating rate only when the loosed gas is larger; the appropriate horizontal opening is corresponding to the gases quantity. The combining of the arced gas distributor and the gases regulating could eliminate the fluidized dead zone in the U-valve effectively.

结果表明，单一流化风对循环量的影响较小，而松动风对循环量的调节幅度比较大；水平孔口开度只有在松动风量较大时对循环量的影响比较明显，而且合适的水平孔口开度与输送风量的大小相对应；利用圆弧形布风板和气量调节相结合可以很好地消除阀体内的流化&死区&。
