While such action was legal and countenanced by international law, there is no doubt in my mind but the enormous amount of money loaned to the allies in this country has been instrumental in bringing about a public sentiment in favor of our country taking a course that would make every bond worth a hundred cents on the dollar and making the payment of every debt certain and sure.

这种行动是国际法所允许和鼓励的，但同时我也确信我国向盟国提供的大量贷款已被用来造成一种公众情绪，它支援我国采取一个能使每张一美元债券值一百美分，使每笔债务能得到可靠偿还的方针。

While such action was legal and countenanced by international law , there is no doubt in my mind but the enormous amount of money loaned to the allies in this country has been instrumental in bringing about a public sentiment in favor of our country taking a course that would make every bond worth a hundred cents on the dollar and making the payment of every debt certain and sure .

这种行动是国际法所允许和鼓励的，但同时我也确信我国向盟国提供的大量贷款已被用来造成一种公众情绪，它支持我国采取一个能使每张一美元债券值一百美分，使每笔债务能得到可靠偿还的方针。

At the same time, the fouling mechanism of membranes given in this thesis can give a reasonable explanation on the change of membrane performance. Our results show that the magnetization of membranes can effectively improve the anti-fouling ability of the PAN- Fe_3O_4 membrane. The obtained result may give insight to the development of new membranes with a good anti-fouling performance in the filtration of blood solution. No chemical bond was found between PAN and Fe_3O_4 in the membrane at room temperature. The addition of Fe_3O_4 can improve the temperatures of dehydrogenated reaction and decomposition of PAN but dot change the glassy transition temperature. The resistance against acid is stronger than the resistance to base for a PAN- Fe_3O_4 membrane.

结果表明在PAN- Fe_3O_4超滤膜制备过程中使用外加磁场作用能有效提高膜的耐污染能力，这一结果为开发适用于血液处理的耐污染超滤膜提供了一种新途径；在PAN- Fe_3O_4超滤膜中，四氧化三铁与PAN在室温下没有形成化学键，也不存在官能团之间的相互作用；添加Fe_3O_4对膜的玻璃化温度没有影响，但能提高PAN环化脱氢反应的温度和分解温度；PAN- Fe_3O_4超滤膜的耐酸性强于耐碱性，在pH值为10以上的溶液中由于水解作用而溶解，使得膜失去使用价值，膜的耐酸性与酸的种类、浓度和氧化性有关。

As a matter of fact, it is a must if the two of you are going to build a lasting bond.

而事实上，这是一个必须的，如果你们两个是要建设一个持久的债券。

Thermal barrier coatings consist of an electron-beam physical-vapor deposited NiCoCrAlY bond coat and 7 wt.% yttria partially stabilized zirconia top coat with a tetragonal phase. The YPSZ top coat shows a columnar grains forming dense clusters with gaps among grain clusters. The roughness of the as-deposited ceramic top coat is relatively low, but some spots of prominent growth defects can be observed. Such defect is a bundle of zirconia columns.

采用EB-PVD方法沉积热障涂层，其粘结层为NiCoCrAlY，陶瓷层为7wt%Y_2O_3部分稳定的ZrO_2，其表层为单一的四方ZrO_2相，其表层比较致密，但有一定的粗糙度，表面存在一些凸出来的斑点状ZrO_2柱状晶，柱状晶粒簇拥成团，团簇间存在间隙。
