ConclusionThe expression of α-B crystallin in IDC is significantly higher than that in DCIS and is positively related to lymph node metastasis. There are also higher levels of expression in the HER2+ and the triple-negative groups. This suggests that α-B crystallin is involved in the process of progression and metastasis of breast cancer.

结论α-B crystallin在乳腺浸润性导管癌中的表达明显高于导管原位癌，与淋巴结转移呈正相关，且在生物学行为更为恶性的HER2+组和三阴性组具有更高的表达水平，提示α-B crystallin蛋白可能参与了乳腺癌的浸润与转移过程。

The results of catalytic activity show that both Ni-B and Ni-P sample have the same kinetic equation for hydrogenation of 1, 3-cyclopentadiene to cyclopentene and the same TOF. Therefore, it can be suggested that they have the similar active site. The catalytic activity of Ni-B sample is higher than that of Ni-P sample, and it is due to the more active sites of Ni-B sample having.

催化活性测试表明，Ni-B与Ni-P催化环戊二烯加氢反应对环戊二烯具有相同的动力学方程，而且两者具有相似的氢转换频率，表明两者的活性中心本质上是相似的，类金属不同导致的电子转移方向的不同仅仅影响反应的初活性，宏观活性的差别在于两者活性中心数量的不同。

此外许多人出现头皮脱屑还与体内的缺乏B族维生素有关，因此调节饮食结构，改善营养状况，每天口服适量的维生素B和维生素E，再加上50至200微克硒元素，这些营养物质对消除头皮屑皆有助益。

AB-Ⅰshowed single and symmetrical peak, a light yellow powder was obtained after dialyzation and freeze-drying. AB-Ⅱand AB-Ⅲwere devided into two parts, collected the main peak, we gained AB-Ⅱ-b which was yellow powder and AB-Ⅲ-b which was brown powder.

AB-Ⅰ、AB-Ⅱ和AB-Ⅲ分别再通过Sepharose CL-4B凝胶层析进一步分级，AB-Ⅰ得到单一对称峰，透析干燥后为淡黄色粉末，AB-Ⅱ和AB-Ⅲ在主峰之前分别有一小峰，收集主峰，得到AB-Ⅱ-b和AB-Ⅲ-b，透析干燥后分别呈黄色和褐色粉末。

To B, or Not To B』,this study propose a 「3-D smiling curve paradigm 」to help Taiwanese machinery firms absolve from the dilemmatic situation between OEM and OBM by providing a wider and extendible thinking frame to formulate the most appropriate strategy for enterprises.

中文摘要『To B， or Not To B』，本研究为面临取舍「专注代工」或「行销品牌」而陷於两难困境之台湾机械业厂商，提供一项更宽广、开阔之思维架构，据以制定企业最佳经营策略，追求转型提升、持续成长。

With stress calculation analysis and experimental verification, it could be concluded that when b/s is small (.2), the disalignment could be restored by polishing. When grater, by repair welding with width no more than 100mm Meanwhile, when controlling stress level is .5, allowable value of disalignment and angle deformation could be .7s.

通过应力计算分析和实验验证可以得出：当b/s较小(b/s.2)时，错边可以用磨削方法进行修复；当b/s较大时，可用堆焊方法进行修复，且堆焊宽度H不超过100mm同时，在控制应力水平不超过1.5时，错边量和角变形量的和可以允许在不超过0.7s的范围内。

Pseudo- oriented solidification microstructures have been found in the rapidly solidified iron disilicide ribbons, and lead to textured structures in the bulk b-FeSi2 based alloys, which means there exists some orientation relationship between the a- and b-FeSi2 phase.

实验发现，快速凝固FeSi2合金薄片粉末中存在伪定向凝固组织，它导致了热压后的b-FeSi2基合金块体材料中的织构。这表明FeSi2合金的a相和b相晶粒之间存在特定取向关系。
