Based on seismic tectonic setting and distribution of small seismic activity, this paper proposes principles for the initial selection of the precursory seismicity "window" and the evaluation method for its validity. Three types of prcmonitary small earthquake activity windows or sensittive positions are found in Sichuan area, namely, the continuous, the mutational and the signal types. Probability indicating seismic events in a specified area by one or several "windows" is given in this paper. Finally,...

Based on seismic tectonic setting and distribution of small seismic activity, this paper proposes principles for the initial selection of the precursory seismicity "window" and the evaluation method for its validity. Three types of prcmonitary small earthquake activity windows or sensittive positions are found in Sichuan area, namely, the continuous, the mutational and the signal types. Probability indicating seismic events in a specified area by one or several "windows" is given in this paper. Finally, problems of the preshock effects of the "window" and its applications are discussed.

本文根据地震构造背景和小震活动分布,提出了初选“窗口”的原则与有效性估计的方法。四川地区检测结果,存在持续型、突发型、信号型三类前兆小震活动窗或敏感部位,文中给出了单个和多个“窗口”反映某区地震的概率。最后就“窗口”的震前“效应”与应用上存在的问题作了讨论。

Pt/Al_2O_3 catalysts were prepared by impregnation method in which Pt loading was fixed at mass fraction 0.5%,and the Al_2O_3 carrier was prepared by sol-gel method. The activity for selective catalytic reduction of nitric oxide by propene in the presence of oxygen over Pt/Al_2O_3 catalyst was investigated and the bonding state of Pt in the samples pre-treated under different conditions was studied.

Pt/Al_2O_3 catalysts were prepared by impregnation method in which Pt loading was fixed at mass fraction 0.5%,and the Al_2O_3 carrier was prepared by sol-gel method. The activity for selective catalytic reduction of nitric oxide by propene in the presence of oxygen over Pt/Al_2O_3 catalyst was investigated and the bonding state of Pt in the samples pre-treated under different conditions was studied. It has been found that the activity window of the catalyst calcined in H_2 is the widest,and it changed little when the calcined temperature increased;the catalyst activity of the catalyst pretreated in O_2 at 523 K is the highest,the activity window shifted to a higher temperature when the calcined temperature increased. The reason of the activity difference is explained by the temperature programmed desorption. According to XPS measurements,the main bonding state of platinum supported on Al_2O_3 is Pt 2+ calcined in O_2 at 523 K,and Pt 0 calcined in N_2 and H_2 at 523 K,respectively. [WT5HZ]

用溶胶 -凝胶法制备 Al2 O3载体 ,浸渍法制备质量分数为 0 .5 %的 Pt/ Al2 O3催化剂 .研究焙烧气氛和温度对选择性催化还原 NO反应活性和 Pt价态的影响 .结果表明 ,H2 焙烧的活性温度区间最宽 ,随着焙烧温度的升高 ,温度区间变化很小 ,5 2 3 K下 O2 焙烧的催化剂活性最好 ,且活性区间向高温方向移动 .活性现象用程序升温脱附实验 ( NO-TPD,NO-O2 -TPD)进行了解释 . XPS研究表明 ,5 2 3 K下 O2 用焙烧 Pt的主要价态是 Pt2 + ,而 5 2 3 K下 H2 和 N2 焙烧 Pt的主要价态为 Pt0 .
