伽师地震与区域断层活动研究

利用GPS、连续倾斜和地震活动性资料分析了伽师地区构造活动的特点和伽师强震群的动力背景，结果表明：在印度洋板块的挤压下，塔里木盆地的右旋腑冲运动是造成南天山区地震活动的主要原因；1996年3月19日伽师阿图什6．7级地震，强烈地影响了该地区块体由向西南倾斜转向北向倾斜，并可能成为诱伽师地区强震群活动的主要动力因素，利用1998年和1999年对该地区GPS测量的结果，给出了该地区断层活动的水平。     

Comparison of convective parameterizations in RegCM4 experiments over China with CLM as the land surface model

区域气候模式Reg CM最新版中引入了新的陆面模式CLM,为了考察在选用CLM时不同对流参数化方案在中国地区的表现,本文进行了五种不同对流参数化方案下—Grell、Emanuel、Tiedtke,Mix(陆地上位Emanuel方案,海洋上为Grell方案)和Mix2(陆地上为Grell方案,海洋上为Emanuel方案)的模拟试验。将模拟的冬、夏季平均气温和降水与观测进行了对比分析,结果表明,Emanuel方案是综合模拟效果最好的。在使用Reg CM-CLM进行中国区域模拟研究时,对流参数化方案推荐选为Emanuel。     

~(12)CO,~(13)CO and C~(18)O observations along the major axes of nearby bright infrared galaxies

We present simultaneous observations of 12CO,13CO and C18O J=1-0 emission in 11 nearby(cz<1000 km s-1) bright infrared galaxies.Both 12CO and 13CO are detected in the centers of all the galaxies,except for 13CO in NGC 3031. We have also detected C18O,CSJ=2-1 and HCO+J=1-0 emission in the nuclear regions of M82 and M51.These are the first systematical extragalactic detections of 12CO and its isotopes from the PMO 14 m telescope.We have conducted half-beam-spaced mapping of M82 over an area of 4×2.5 and major...     

The relationship between the radio core dominance parameter and the spectral index in different classes of extragalactic radio sources

Active galactic nuclei(AGNs)have two major classes,namely radio loud AGNs and radio quiet AGNs.A small subset of the radio-loud AGNs is called blazars,which display extreme observational properties,such as rapid variability,high luminosity,high and variable polarization,and superluminal motion.All of those observational properties are probably due to a relativistic beaming effect with the jet pointing close to the line of sight.Observations suggest that the orientation can be expressed by a core-dominance p...

地壳形变前兆及其应变量转换

归纳了自1975年以后华北地区13次中强以上地震的地壳形变短临前兆异常60例。统计地壳形变短临异常与地震的定性关系，发现距震中较远的台站异常出现较早，较近的台站异常出现较晚，地震的震级与异常的空间展布范围成正比，异常往往倾向震中或背向震中。跨断层的位移型形变异常形态有两大类：一类是趋势性异常变化，另一类是高频波动。本文提出了将连续型形变转化为应变的方法。从1989年10月16日大同－阳高61级地　震和1991年3月26日大同－阳高5．8缓地震的实例可见，地震往往发生在高应变区或其附　近，异常量级可达10－6。

新疆康古尔塔格断裂带地球物理场及深部地质特征

利用重力、航磁、航电、航空γ能谱、地震测深等多种地球物理资料,对新疆北部的康古尔塔格断裂带深部地质特征进行了探讨.认为该断裂带两侧的地壳结构有较大差异,北侧地壳为二层结构,上地壳中发育有高密度、强磁性、高速度的镁铁质岩;南侧地壳为三层结构,同时有低速度层发育.康古尔塔格断裂带是划分准噶尔与塔里木两大板块的一条重要界线.
