查询词典 modal

Bob has been in the forefront of transportation operating practices and procedures, having had hands on experience with every phase of rail operations, intermodal, port operation on dock, near dock and drayage, train dispatching from non-signaled train order territory through computer assisted traffic control mainline· His 30 years of experience span the period from the rigidly regulated practices of the late 1960's encumbered with volumes of paperwork through the deregulated virtually paperless environment that gave rise to multi-modal deregulated shipping alternatives to create market demand and augment many manufacturing entity efforts through vastly improved efficiency procedures to dramatically reduce costs and improve service

吉农先生一直站在运输经营和程序业的前沿，并有各项铁路业务，联运，在港口经营码头及码头附近区域，对复式列车调度的全港电脑辅助交通控制等方面的工作经验。他30多年的工作，经历了由六十年代后期的大量传统办公方式到现在的无纸化办公，这都使其得以运用多种航运调节办法，创造市场需求，通过大幅度提高效率大大降低成本和提高服务。

A bstract: Load Identify has always been one of the important aspects in dynamics. This paper gives us a new way to identify one point dynamic load which is act on a sheet. The method is based on the modal theory and Duhamel integral. Result obtained from a simulation indicates that the method is simple and easy to operate especially when it is used to identify transient load.
