不起作用的

In this paper,the important role played by an infrared spectrometer in the kind identification of gemmology,the determination of optimal treatment and the distinguishment of natural gems from synthetic gems without prefabrication and abrasion is presented by way of example.

It is not always easy for whites to realize that the violence of black rhetoric, the calls of "get Whitey" and "kill the pigs," spring from a deep wound caused by 31 centuries of blatant injustice and from a feeling that polite, peaceable methods have not worked.

白人们常常难以认识到黑人的暴力口号——"打倒白人"，"杀了这些猪"，是从3100年粗暴的不公正待遇的创伤中汩汩涌出来的，是因为黑人们意识到礼貌和平的方式起不了作用。

The oxidant 〓 plays indirect role in dissolving gold, and mainly controls the mix potential of Au in the alkaline thiourea solution. In which the "mix potential"is the decisive factor affecting the dissolution of gold. The reaction driving force is enough to have formamidine disulfide oxidize Au to Au〓 at the potential of about 0.4V. And then thiourea molecular complexes with Au〓 ion soon, which causes the fast dissolution of gold in the alkaline thiourea media. The dissolved weight of gold in 0.25 M thiourea solution with 0.05M Na〓SO〓 and 0.1M 〓 of pH 12. 5 by air at the temperature of 303K is 7. 8mg·cm〓 within 1hr.

在碱性硫脲溶金过程不起直接作用，而是通过S〓O〓来控制二硫甲脒有效形成的金在溶液中的混合电位；&混合电位&是影响碱性硫脲溶液溶金与否的决定性因素，在0.4V左右，有足够的推动力致使二硫甲脒氧化Au成Au〓，随后硫脲与Au〓络合形成稳定的络离子Au〓，从而使金快速溶解；温度为303K、pH为12.5时，在含0.05MNa〓SO〓、0.1M 〓及0.25M硫脲的溶液中，鼓入空气，金的溶解量在1hr内为7.8mg·cm〓；铜只有微量溶解，银、镍、铁则几乎不溶解。

Those who took the leading part in the actual trial (like that honorable grain merchant who could neither read nor write but who knew all about the will of the Gods and therefore was loudest in his accusations) were undoubtedly convinced that they were rendering a great service to the community by ridding the city of a highly dangerous member of the so-called 'intelligentsia', a man whose teaching could only lead to laziness and crime and discontent among the slaves.

在审判中起主导作用的那些人（例如那个既不会读又不会写、只因为通晓上帝旨意而成为起诉中最卖力气的可敬的粮贩子）深信他们审讯苏格拉底是在为社会尽职，为城市除掉一个所谓'知识界'中的最危险分子，一个只能教给奴隶懒惰、犯罪和不满的人。

The unreasonable design of the system of educational loans in our country mainly results from the lack of warrantors and uselessness of financial subsidy in promoting.It is necessary to change the educational loans into loans for education.

摘 要：我国的&助学贷款&制度设计不合理，主要是担保方缺失，财政贴息起不到促进的作用，有必要把财政的&助学贷款&改成商业信用的&贷款助学&。
