he lithosphere stretching, subsidence and basement thermal history of the Songliao, Yinggehai and Qiongdongnan basins in East china have been investigated by using backstripping technique and stretching models. The subsidence curve of the Songliao basin characterizes a rift basin history evolving from synrift rapid subsidence to postrift thermal subsidence. The calculated stretching factor of the basin is about 1.8 to 2.0 and the horizontal extension is about 55-60 km. The reconstructed subsidence curves of the Qiongdongnan and Yinggehai basins show that the basins underwent several rapid subsidence episodes, which has been interpreted as the result of a multiple stretching of the lithosphere. The total mean stretching factors of the Qiongdongnan and Yinggehai basins, calculated by using a multiple instantaneous stretching model, are about 1.7-1.9 and 2.5-3.0 respectively. The stretching factors of these basins, estimated from subsidence, are consistent with those determined from crustal thinning. The reconstructed thermal histories of these basins are in agreement with the geological {2..

利用常规高空资料、地面观测资料、物理量资料和北海探空资料，对2.15年11月钦州市两次大暴雨过程的环流形势、水汽条件、不稳定条件和动力条件进行对比分析。结果表明：（1）两次过程暴雨发生时钦州位于副高西北侧和南支槽前正涡度区，受到南支槽和副高共同影响。“1106”过程副高西界经向度较大，南支槽较深，孟加拉湾有低压使水汽通道维持，低层切变线位置偏北，广西沿海有风速辐合。（2.两次过程500hPa上588线都有先东退再西伸北扩的变化特点，“1106”过程588线的位置更偏北偏西，与降雨区距离更近。（3）两次过程都受高压后部形势影响，西南低压发展，暴雨发生前受到冷空气影响。（4.两次过程850hPa以上和92.hPa以下都有水汽辐合，但“1106”过程的中层水汽辐合持续时间更长，强度更强。（5）两次过程发生前都是上干下湿的对流性不稳定层结，且湿层较厚，“1106”过程不稳定能量相对较大。（6）两次过程暴雨发生时在近地层和中层都有明显的辐合，上升运动发展旺盛。

Progress in Natural Science:Materials International 2005年第1期 35-41页

作者： JING Jun, YIN Xiezhen* and LU Xiyun(Department of Modern Mechanics, University of Science and Technology of china, Anhui 2.002., china)

The kinematics and hydrodynamics of the escape response of yellow catfish (Pelteobagrus fulvidraco) is investigated. It is observed from digital high-speed camera that all the escape response of yellow catfish is a C-type fast-start, which is characterized by the C-shape of the fish body at the end of the first contraction of the lateral musculature. Based on the analysis of the mass center movement and the performance of the caudal fin, the fast-start process can be divided into two stages: in stage one the fish body rotates rapidly around its mass center and in stage two the fish begins moving straightly. Theoretically, the Weihs’ model is employed to obtain the forces, moments and turning angular accelerations acting on the fish during the escape response. The results are in good agreement with the experimental observation. Furthermore, muscle strain at different locations along the body is calculated. At last, the dynamical performance of the escape response is explained.

由于运维时间长,RZB钻孔应变仪存在元器件老化、材质蠕变等问题,使传感器性能不断发生变化,需要定期对其进行原地静态物理标定。目前采用的以压电陶瓷为核心的静态物理标定方式存在迟滞、蠕变、非线性等缺陷,使标定结果精度差、误差大。本文设计了以陶瓷马达为核心、光栅传感器作为反馈、RS4.5总线为基础的远程线性标定机构,实现了RZB钻孔应变仪原地线性标定功能。在实验室开展原地线性标定模拟试验,传感器满量程的标定数据结果表明,标定分辨率达到2.m,线性度优于1%。
