The crystalline phase, morphology, crystalline size and specific surface area were tokened by using thermogravimetric analysis and diferential thermalanalysis, X-ray difraction, transmission electron microscopy, infrared spectroscopy and BET.

同时运用热重/差热、X射线衍射、透射电镜、比表面吸附、红外等多种测试手段对Cu2+/TiO2光催化剂的晶型、粒子形貌、比表面积进行了表征。

In this paper, the noise sources of the EBCCD imaging system have been analyzed and a SNR model has been established. It shows that the SNR of output image is related not only to the input illuminance on the cathode but also to the spatial frequency of the input image. This has been proved by a series of experiment. Unperfectness of the detecting equation has been pointed out in this paper.

分析了电子轰击电荷耦合器件微光成像系统的噪声源，建立了系统的信噪比模型，指出了在微光成像系统本身的增益和量子效率等性能确定的条件下，成像系统输出图像信噪比不仅仅与输入面照度有关，还与输入图像的空间频率有关，并通过实验得到了证明，指出了经典的图像探测方程的不完善之处。

Spanish cast aside before the start of this season's two Champions League qualifiers aside, Atletico this season, took part in the Champions League group stage has 6 games, the EU 6 games, 12 games knockout World War, as a whole, Atletico in 12 games before the European War get 4 wins 4 level 4 and losing many of them home 2 to 1 edge Ke Basa, 2 to 0 win over Athletic Bilbao and other wonderful performances, but if just look away, Atletico battle only get 8 wins, 2 1 5 negative record.

抛开本赛季西甲开赛前的两场欧冠资格赛不论，马竞本赛季已经参加了欧冠小组赛6场、欧联淘汰赛6场共12场欧战，整体来看，马竞在12场欧战前取得4胜4平4负的战绩，其中不乏主场2比1力克巴萨，2比0轻取毕尔巴鄂等精彩演出，但是若只看客场，马竞8战则只取得1胜2平5负的战绩。

In short, what cause is more just, and consequently, what war is greater, than that which re-establishes social truth, restores her throne to liberty, restores the people to the people, restores sovereignty to man, replaces the purple on the head of France, restores equity and reason in their plenitude, suppresses every germ of antagonism by restoring each one to himself, annihilates the obstacle which royalty presents to the whole immense universal concord, and places the human race once more on a level with the right?

总之，树立社会的真理，恢复自由的统帅地位，把人民还给人民，把主权还给老百姓，把紫金冠重新戴在法兰西的头上，重新发挥理智和平等的全部力量，在各人自主的基础上消灭一切仇恨的根源，彻底摧毁君主制设置在通往大同世界大道上的障碍，用法律划一全人类的地位，还有什么事业比这更正义的呢？也就是说，还有什么战争比这更伟大的呢？
