Earthquake Research in china 1998年第3期12卷 3-16页

作者： Ma Lin, Zheng Sihua, and Xue Fengcenter for analysis and Prediction, CSB, Beijing 10003.,{2.

Based on the method of "two-dimensional depth structure of the crust" proposed by Horiuchi et al., about 5000 arrival times of 3.3.local shallow earthquakes recorded by the Beijing Seismographic Network from 1990 ~ 1993.are used to investigate the depth distribution of Moho discontinuity beneath Beijing and its adjacent area. We simultaneously determined the hypocenter parameters and P- and S-wave station corrections. The data of the North china Network were also investigated. The results are as follows: (1) The depth distribution of Moho discontinuity becomes shallower from the northwest to the southeast, i.e., in Zhangjiakou area, the Moho discontinuity is located at a depth range from 40~42.km. In the Beijing area, it is 3.~3. km. However, at the eastern and southeastern part of this area, it is only 2.-3. km and 3.~3.2}km, respectively. (2. Beneath the Tangshan area, there is another elliptic interface shallower than the Moho discontinuity. Separately, its major and minor axis is approximately

Mobile agents(MA) are autonomous software entities that are able to migrate across heterogeneous network execution *** and autonomy compensate the deficiencies of distributed technology pretty well. Thus,mobile agents have wide application *** the security issues with mobile agents have not been solved and are becoming obstacles for the application of mobile *** with host protection,the research on mobile agent protection is still at the beginning *** is a technique in which the mobile code producer enforces the security policy by applying a behavior transformation to the code before sending it to run on different *** paper presents a protection scheme of mobile agent in network management application,which combining method of extending inheritance hierarchy tree and time checking technology to protect the security of *** protection scheme is tested in actual network management environment,which can effectively identify the malicious host.

鄱阳湖血吸虫病重疫区居民连续6年吡喹酮化疗依从性研究

第四届全国磁性薄膜与纳米磁学会议

作者： Wang Zhihong Chen Kun Zhou Yu center of Nanomaterials analysis,University of Electronics Science and Technology ,Chengdu 610054, P.R.{2.

＜正＞ We have studied the microstructure and magnetic domain structure of thin Fe film by magnetic force microscopy （MFM）. Due to the high lateral resolution of MFM we have been able to study the magnetic structure of a single domain. Two series of iron thin films have been grown on microcrystalline glass substrate by DC magnetron sputtering. They were prepared at different Ar pressures and annealing time. The result by magnetic force microscopy show characterize both surface morphology of the films and their local magnetic properties.
