Strain waves in colliding bars having nonparallel faces

The paper reports the experimental investigation data for the effect that nonparallel faces of bars under impact exert on the parameters of longitudinal and bending strain waves generated in the bars. The changes in stress magnitudes in the bar under impact with growing angle of the impact faces offset are described. __________ Translated from Fiziko-Tekhnicheskie Problemy Razrabotki Poleznykh Iskopaemykh, No. 6, pp. 73–78, November–December, 2006.     

运用古地磁方法测定油气成藏时限——以桩海地区下古生界潜山油气藏为例

运用古地磁厘定油气成藏时限是一种新的岩石地球物理方法。对采于桩海地区下古生界的6块岩心样品进行了系统交变退磁实验,分离出2个正极性分量:A分量(10～30mT)是现代地磁场的重磁化;B分量(30～60mT)是新生代烃类流体与下古生界碳酸岩储层相互作用的结果,对应的古地磁极位置为288.95oE、73.58oN。参考华北地块新生代古地磁极移曲线,推定本区下古生界古潜山油气藏的成藏时限为晚第三纪中新世早期(14～18Ma)。这种新方法在中、新生代油气藏成藏时限研究中具有一定的应用前景。     

Efficient and accurate waveguide mode computation using BI‐RME and Lanczos methods

In this paper, a special purpose algorithm for solving large eigenvalue problems based on the Lanczos method is successfully applied to an engineering problem: the electromagnetic analysis and design of passive waveguide devices. For dealing with such complex problems, the boundary integral‐resonant mode expansion (BI‐RME) technique has been recently proposed. This technique solves integral equations (IEs) through the well‐known method of moments (MoM), thus leading to structured eigenvalue problems. These problems frequently become very large when solving complex arbitrary geometries with high accuracy. In such cases, the eigenvalue problem cannot be efficiently solved with standard methods by means of personal computers, essentially due to CPU time and memory allocation requirements. In this paper, we propose an alternative technique, based on the Lanczos method, for the fast and accurate solution of large BI‐RME generalized eigenvalue problems. The novel theoretical aspects of this approach, as well as the impacton the original BI‐RME formulation, are described. Comparative benchmarks are also successfully presented for the full‐wave analysis and design of real passive microwave devices. Copyright © 2005 John Wiley Sons, Ltd.
