Discussion on amending and Compiling the Historical Earthquake Catalogue

Earthquake Research in China 1999年第1期13卷 3-7页

作者： Shi Zhenliang and Cao XuefengInstitute of Geophysics, CSB, Beijing 100081, China

In this paper, some opinions related to amending and compiling the historical earthquake catalog are proposed. They include the following points: (1) the catalog should be based on historically recorded facts; (2) we should consider the accuracy that could actually be attained through the use of historical earthquake data; (3) emphasis should be placed on field survey of historical earthquakes; (4) use engineering seismology and earthquake prediction to develop research in historical earthquakes.

Response of bacteria in the deep-sea sediments and the Antarctic soils to carbohydrates: Effects on ectoenzyme activity and bacterial community

The response of bacteria to various carbohydrates in the deep-sea sediments and the Antarctic soils was investigated using cellulose, chitin, and olive oil. It was found that the carbohydrates significantly increased the corresponding specific ectoenzyme activity （β- glucosidase, β-N-acetylglucosaminidase, lipase） in the samples from deep-sea sediments. In the case of Antarctic soil samples, the cellulose or olive oil amendments had minor or no effect on β-glucosidase or lipase activity, except the chitin which stimulated β- N-acetylglucosaminidase production. The responses of the bacteria in the deep-sea sediment sample WP02-3 and the Antarctic soil sample CC-TY2 towards the chitin amendment were further analyzed. Chitin amendments were shown to stimulate the ectoenzyme activity in all the tested sediments and the soils. The bacterial response before and after the carbohydrates amendments were compared by denaturing gradient gel electrophoresis and quantitative competitive polymerase chain reaction. Significant changes were found in the structure and density of the bacterial community in the deep sea sediments as compared to the Antarctic soil sample, where the effects were relatively lower. There was no change in the bacterial population in both studied samples in response to carbohydrates amendments. These data indicate that the bacterial communities in the oligotrophic deep-sea sediments are more dynamic than that in the Antarctic soils as they respond to the nutrient sources efficiently by regulation of ectoenzyme activity and/or changing community structure.

当下对于“五四宪法”历史地位的定位和描述混淆不清。通过对“五四宪法”和《中国人民政治协商会议共同纲领》的文本的比较分析，研究“五四宪法”的性质及其历史地位，认为“五四宪法”的制定和颁布不是制宪而是修宪，其历史地位不是“新中国第一部宪法”，而应当是“中国第一部社会主义(性质的)宪法”。
