星叶石族矿物红外光谱研究

在新测定的星叶石晶体结构资料的基础上,对星叶石矿物进行了详细和红外光谱研究,对比了单斜及三斜星叶石的红光谱特征,并对星叶石中工外吸收振动的归属问题进行了讨论。     

FGGE期间全球30—50天振荡的结构

对整个365天全球6层的FGGE III b资料的5个变量进行时间序列分析和频率滤波分析以研究30—50天低频振荡的结构,这个研究得出了30—50天低频振荡的大振幅所在地区,并描述了通过这些地区的垂直结构,还着重讨论了对流层低层经过30—50天带通滤波后最大风速的季节变化。FGGE年的一些主要结果表明30—50天低频振荡的最大振幅出现在夏季风地区和对流层上层的高纬度地区。在北半球冬季,活跃的地区位于中太平洋的赤道带上。

M87的宽波束射电观测

在本文中我们给出了对M87的宽波束的射电观测结果。结合Ceccareli等人对室女座的红外观测资料(1982),我们论证了,为了便于统一解释射电及红外的观测资料,在M87的周围除了一个高温的晕(～10~8K)外,还可能存在一个微温的延伸晕(～10~5K)。这个微温的晕将会造成M87和高温晕的引力封闭。

Laboratory detection of a new interstellar free radical CH2CN(2B1)

An asymmetric-top free radical CH2CN, which as a 2B1 ground state, was detected for the first time by laboratory microwave spectroscopy. The radical was produced in a free-space absorption cell by a DC glow discharge in pure CH3CN gas. About 60 fine-structure components were observed for the N = 11-10 to 14-13 a-type rotational transitions in the frequency region of 220-260 GHz, and many hyperfine resolved components for the N = 4-3 and 5-4 transitions in the 80 and 100 GHz regions, respectively. The molecular constants, including the rotational constants, centrifugal distortion constants, and spin-rotation coupling constants with centrifugal distortion correction terms were determined from the fine-structure resolved transitions, and the hyperfine coupling constants due to the hydrogen and nitrogen nuclei were obtained from the low-N transitions. As a result we assigned U100602 and U80484 from Sgr B2, and U40240 and U20120 from TMC-1, to the N = 5-4, 4-3, 2-1, and 1-0 transitions with K-1 = 0 of the CH2CN radical.     

Choice of conodont Idiognathodus simulator （sensu stricto） as the event marker for the base of the global Gzhelian Stage （Upper Pennsylvanian Series,Carboniferous System）

We propose that the level at which the conodont species Idiognathodus simulator （Ellison 1941） （sensu stricto） first appears be selected to mark the base of the Gzhelian Stage, because we believe that this is the optimal level by which this boundary can be correlated. This taxon has a short range and a wide distribution, as shown by correlation of glacial-eustatic cyclothems across the Kasimovian-Gzhelian boundary interval among Midcontinent North America and the Moscow and Donets basins of eastern Europe, based on scale of the cyclothems along with several aspects of biostrati- graphy. Outside of these areas, I. simulator （sensu stricto） is known also from other parts of the U.S., and is reported from the southern Urals and south-central China in its expected position between other widespread taxa. Its first appearance is consistent with the current ammonoid placement of the boundary （first appearance of Shumardites cuyleri）, and it is also compatible with certain aspects of the distribution of Eurasian fusulinid faunas （e.g., lectotype ofRauserites rossicus）.     

选择性效应的数值模型及△V／L准则

具有合理的传导通道的地球模型的麦克期韦议程组数值解表明，电场值仅在某个特定的区域（即在通道端部的上方）内增加，因而解释了观测到的选择性效应。在这个范围内，虽然电场值可能达到仪器能够探测到的值（5－10mV/km),但是磁场值仍保持低值（10^-2nT)。这些结果和最近由解析解所获结果是吻合的（Varotsos,et al,1998)。用数值解和解析解都很自然地解释△V/L≈常数这个准则。但是这个准则不应当应用于电性结构极不均匀的地区。     

两类转换断层

关于冷却消长变化的理论模式与实验工作 ,不仅确定某些断层一开始生成时即为转换断层 ,而且提示存在着两类转换断层 ;它们被名为“边界转换断层”和“海岭转换断层”。其不同在于所描述板块边界的级次和状态 ,以及 /也可能与已知板块的年龄有关。     

用于地震危险性分析的统一的伊朗地震目录

地震活动性分析把记录的地震事件作为基础数据．我们提供了一个伊朗及其邻近地区的统一地震目录用于伊朗的地震危险性分析．由于最大可信地震的复发时间不能直接从mb估算，对不同地震构造区，我们建立了经验关系，将mb转换为MS，它是我们需要的震级标度．地震目录完整性研究表明，许多中、小地震被遗漏，特别是在历史上和仪器记录早期．
