摘要：This study investigated the impact of different verification-area designs on the sensitive areas identified using the conditional nonlinear optimal perturbation （CNOP） method for tropical cyclone targeted *** sensitive areas identified using the first singular vector （fsv） method,which is the linear approximation of CNOP,were also investigated for *** analyzing the validity of the sensitive areas,the proper design of a verification area was *** cyclone Rananim,which occurred in August 2004 in the northwest Pacific Ocean,was *** sets of verification areas were designed;one changed position,and the other changed both size and *** CNOP and its identified sensitive areas were found to be less sensitive to small variations of the verification areas than those of the fsv and its sensitive *** larger variations of the verification area,the CNOP and the fsv as well as their identified sensitive areas changed *** terms of reducing forecast errors in the verification area,the CNOP-identified sensitive areas were more beneficial than those identified using *** design of the verification area is important for cyclone *** verification area should be designed with a proper size according to the possible locations of the cyclone obtained from the ensemble forecast *** addition,the development trend of the cyclone analyzed from its dynamic mechanisms was another *** the general position of the verification area was determined,a small variation in size or position had little influence on the results of CNOP.

摘要：LTE-M是满足城市轨道交通综合业务需求的车地通信系统。列车接入单元(TAU)设备是LTE-M系统中重要的组成部分,是车地无线通信的重要环节,列车上的PIS,CCTV,CBTC设备均通过TAU设备接入到LTE系统。本文论述了TAU自动测试系统的设计与实现,该测试系统保证了TAU设备批量生产质量的可靠性。
