Since H〓S and SO〓 adsorbed on TiO〓 could react with each other and TiO〓 is the medium of their electron transfer, thus SO〓 could not be adsorbed quite strong on the active site of TiO〓, which makes it more resistant to sulfating and increase the stability of catalyst. Finally, the model and mechanism of the reduction of SO〓 by NH〓 to elemental sulfur is advanced as follows: on the sulfide catalyst, ammonia is decomposed to N〓 and H〓, and H〓 reacts with SO〓 to form the intermedium of H〓S; then H〓S and SO〓 react as Claus reaction on TiO〓 catalyst.

反应系统中过量水蒸气的存在使催化剂表面某些活性位被水蒸气抑制使活性和选择性有较大幅度降低，但这种影响是可逆的，不会造成催化剂永久性中毒；另外当单质硫和水蒸气同时存在时，在〓催化剂上能够生成硫化氢和二氧化硫，而且由于硫化氢和二氧化硫化学吸附能力不同而导致它们的脱附顺序不同，硫化氢的生成温度总是低于二氧化硫的生成温度，说明过量水蒸气的存在会导致氧化物催化剂上逆克劳斯反应的发生；而在硫化物催化剂上几乎没有硫化氢和二氧化硫生成，说明硫化物催化剂能够抑制逆克劳斯反应的发生。

On the foundation of the analysis,a fault diagnosis method which is an advanced pattern recognition method is proposed and a fault diagnosis system of generator excitation power unit based on virtual instrument is developed.It is proved by experiment that the fault diagnosis system can precisely judge which thirstier goes wrong and get accurate diagnosis result.

发生晶闸管直通故障时，瞬间将造成相电压短路，短路电流使保护电路动作；而发生晶闸管开路故障时(如晶闸管器件门极损坏或触发脉冲丢失等故障)，功率单元仍然工作，但输出励磁电压的脉动增大，平均值降低，这种带病工作导致励磁电压波形产生畸变，从而导致了发电机工作在不稳定状态，同时也加大了对电网的干扰[2]。

The author has made researches on the social occurrence of man's functions of symbols and finds out that the occurrence of babies' self-consciousness is achieved under the conditions babies have possessed dualistic attention-----that is to say, attention can concentrate on two signal sources at the same time or it has two focus of attention.

论文摘要本文作者对人的符号功能的社会系统发生进行了研究，发现婴儿自我意识的发生是在婴儿已经具有二元注意--即注意力能同时集中到两个信号源或者说有两个集中点--的条件下实现的，这种并行性注意使一种称为反身性条件反射建立成为可能，并形成了具有符号功能的神经机能组织--二联体。

When diaryl ketones were treated in DMF promoted by samarium metal with TMSCl as activator, diaryl ketones react with DMF followed by a carbene rearrangement to afford benzoins unexpectedly, with benzils were obtained as byproducts, the formation of which may be explained as a result arising from the auto-oxidation of benzoins. Further investigation found the reaction could also proceed smoothly when I〓 was used as an activator. The reaction could occur as well in SmI〓/THF, though benzoins were obtained in relatively low yields.

发现当有活化剂TMSCl存在时，金属钐能有效的促进二芳酮和DMF的发生反应，偶联后发生卡宾重排，意外地得到苯偶姻类化合物，同时伴随着少量的二芳基二酮副产物生成，我们推测二芳基二酮的生成可能从苯偶姻的自氧化而来；进一步的研究表明，用一定量的I〓活化金属钐，该反应也可以顺利的进行，并且可以得到相对更好的实验结果。

In view of easy fusion flaw between connecting of doubler strake and deck plating or bottom plating strengthened, this paper puts forward a fire-new welding technics for the purpose to improve the technics of welding connecting of doubler strake. Under the help of this way, connecting of doubler strake can be penetratingly fillet welded, but not fuse with deck plating or bottom plating strengthened, at the same time the figure of weld surface can also be managed for increasing fatigue strength of connecting.

本文针对复板条对接接头容易和被加强的甲板或船底板发生粘连的缺点，从改善复板条对接接头的工艺入手，提出了新的焊接工艺，使得复板条对接接头既能保证完全焊透，又不会和被加强的甲板或船底板发生粘连，同时对焊缝表面形状进行处理，以提高接头的疲劳强度。

The study result indicates that flood usually oc curred in the climate transition period. Based on the result, the author believe s that the appearance of flood may be in a certain relation with the abrupt clim ate event in the process of the global climate evolution.

同时在研究中还发现，古洪水多发生在气候转型期，因此笔者提出古洪水的发生可能与全球气候变迁历史中的突变事件有某种必然的联系。

It is because we are now able to access to such information is found in the West of the early AIDS, found that many medical and health workers, including doctors and nurses in the treatment of patients in the process of hand-cut their own, such things happen in the future, the following tested for some time, at the same time after the incident in the day asking them to record their feelings, or performance, but in such a strict observation of the circumstances, some people think that after the incident in this period of time there is a species is similar to a very mild cold symptoms have passed very quickly, of course, after this part of the personnel to prove that he is infected, in turn, we believe that after infection some people have such a performance, but the actual There are a considerable number of people simply do not feel.

就是因为我们现在能查阅到的这些资料是在西方社会艾滋病发现的早期，发现很多医疗卫生工作者，包括医生护士在诊治病人的过程中，把自己的手划破，出现这种事情以后，隔一段时间经过检测，同时在这个事件发生以后要求他们每天记录自己的感觉，或者说是表现，只是在这种严格的观察的情况下，有一部分人觉得在这个事件发生以后的一段时间里有一种类似于感冒的很轻微的症状，很快就过去了，当然这一部分人事后也证明他确实是感染了，回过头来讲，我们认为感染了以后有一部分人会有这样的表现，但是实际上有相当一部分人根本就感觉不到。

These aches and injuries were listed orderly : knee、 ankle、 plantar fascitis、calcaneus、Achilles tendonitis、hip, some happened on high-arched group, some on low-arched group, and some appeared both high-and low-arched group at the same time.

有些伤害常发生在高足弓群、有些则发生在低足弓群，有些则是同时出现在两种足型上。

The economy and social causes in China have procured great achievements in those twenty years. The visages of cities have experienced great changes. During the construction, the conflicts of various concepts and modes such as tradition and modern, foreign and native, civilization and blindness arise incessantly. At the same time, the fusion of different culture and concepts also occurs all the time.

中国经济和社会事业的发展在最近的20年里取得了巨大的成就，城市的面貌发生了很大的改观，在建设中，历史与现实、传统与现代、西洋与本土、文明与愚昧，各种观念与样式的冲突此起彼伏，同时，文化与观念的融合也在不断地发生。

Cardiac toxicity was minimal in both groups, the editorial notes, adding that this is a major adverse effect of trastuzumab. However, the trialists point out that there was a bias, as they had selected women who had normal cardiac function after having received various other therapies (including anthracyclines and taxanes) as well as trastuzumab. Also, since the duration of observation was limited, the possibility of late events cannot be excluded."Nevertheless, the low incidence of adverse cardiac events is reassuring," they comment.

主编表示，两组之间发生心脏毒性的比例相似，且这是trastuzumab主要的副作用；然而，研究者指出其中有误差，因为他们挑选已经接受其它不同治疗（包括anthracyclines类药物与taxanes类药物）以及trastuzumab后心脏功能正常的病患；同时，因为试验观察时间长度有限，晚期发生不良反应的可能性并不能排除；他们的评论是，不管如何，心脏不良反应发生率低是可靠的。
