Several transient compounds were synthesized by the homo- and heterogeneous reactions of reactive halogen compounds, In-situ ultraviolet photoelectron spectroscopy and photoionization mass spectroscopy as well as theoretical calculations were used to study their molecular structures, stability and molecular orbital properties, their electronic structures and geometric structures were obtained for the first time; Simultaneously, the electronic structure and thermal dissociation of acetyl peroxynitrate and trifluoroacetyl peroxynitrate which have great importance in the atmospheric chemistry were studied; The substituent effects of series of halopyridines and halothiophenes were studied by the ultraviolet photoelectron spectroscopy method for the first time. The atmospheric chemical reaction between peroxyacetyl radicals with IO radicals as well as the dissociation of the most stable isomer of CH3COIO3 were calculated by density functional theory, it was found that the CH3COOIO2 isomer may be act as a new reservoir of inorganic iodine in the stratosphere.

Must not the only fruitful renaissance be the one that reawakens the impulse of the Cartesian Meditations: not to adopt their content but, in not doing so, to renew with greater intensity the radicalness of their spirit, the radicalness of self-responsibility, to make that radicalness true for the first time by enhancing it to the last degree, to uncover thereby for the first time the genuine sense of the necessary regress to the ego, and consequently to overcome the hidden but already felt naivete of earlier philosophizing?

在近代，对一个完全有活力的哲学的渴望，已经引起了一个又一个文艺复兴，唯一富有成果的文艺复兴难道不就是唤醒笛卡尔式《沉思》的推动力吗？——不是要用那些内容，不这样做，而是以更大的强度去重新实现这些精神的彻底性、自身负责的彻底性，通过提升到最后的程度上去把彻底性第一次真正实现，于是去第一次揭开必须回退入我思『ego cogito』的真正含义，最终去克服早期做哲学的朴素性（——这已经被感到了，但依然隐藏着）。【英p5/3，德p47/2

For many young people, the first time they notice the closed door is when they try to go clubbing."The first time the guy at the entrance says:'You're not coming in', you accept it," says Nadir Dendoune, a journalist from Saint-Denis.

TIP- Start the first level on casual and turn off auto tequila time. When you are at the top of the stairs with the huge railing make sure you have a full tequila time bar. Slide down the bar and shoot the 2 signs then shoot the next two things. When you are almost at the end of the rail look over at the cart slightly to your left and jump from the rail onto the cart.

作者介绍了一个比较好完成的地点：第一关最后选择简单难度关闭自动tequila time（自由选择开启tequila time可以更好的积攒style combo，因为tequila time时杀敌积攒combo更多）当你在一个有巨长滑竿的楼梯顶保证自己的tequila time满，然后跳上滑竿打掉2个牌子和之后的2个东西

A Jiang is not a woodenhead, but still can make a mistake occasionally, calculating a tutorial so is newest the most complete, the problem still may appear when we are operated for the first time, and because be first time, write down the whole process that oneself handle very hard clear, bring about the person that has experience repeatedly possibly finally to come over to also cannot have installed your server completely.

阿江并不是一个笨人，但是有时候还是会犯错误的，所以就算教程是最新的最完整的，我们第一次操作的时候仍然可能出现问题，而因为是第一次，很难记清自己操作的全部过程，最后可能导致连有经验的人过来也无法完全设置好你的服务器了。
