卫星云图接收系统使用中若干问题的处理

静止气象卫星中规模利用站处理系统,是由中国气象局国家卫星气象中心研制的。该系统硬件由天线及馈源、本振及高放、一体化接收板及计算机图像处理终端等四个部分组成。系统硬件连接较方便;软件操作界面友好,方便灵活,自动化程度高,并支持网络。现就系统安装调试和业务运行中曾出现过一些现象及处理步骤介绍如下：现象一：到收图时间,系统不能自动启动接收处理批作业,而手工启动正常。处理：系统自动启动接收处理批作业,是通过在“管理”菜单中“自动批作业选择”项中激活“接收处理批作业”一项而实现的。其要求“Ｓ－ＶＩＳＳＲ接…     

环境激素对水产品安全性的影响及预防

水产品的安全性与许多因素有关,而环境激素是其中一个主要因素,由于其危害不是马上暴露出来,所以一直未引起人们的重视,但国外学者研究表明环境激素通过环境介质和食物链进入人体内与受体结合后,就会在体内发出错误信息,从而破坏生物体的正常代谢,造成生物体的激素分泌失调和生

两种地震预警定位方法的比较

In this paper, according to the Fujian Seismic Network earthquake catalog records, the Tnow method and the Four Stations Continuous Location method （hereinafter called FSCL） put forward by Jin Xing are inspected by using P-wave arrival information of the first four stations of each seismic event. Results show that for earthquakes within the network, both methods can obtain similar location results and location deviations are small for the majority of the events. For earthquakes outside the network, the location deviation may be amplified as the epicentral distance increases, owing to the seismic station distribution which spread toward the side of the epicenter and the small opening angle between seismic stations used for locating and epicenter. For the FSCL method, the impacts of the wave velocity on the location results may be significant for earthquakes outside the network. Thus, selecting a velocity model which is similar to the actual structure of the wave velocity will contribute to improving location results of earthquakes. The FSCL method can locate more seismic events than the Tnow method. It concludes that the Tnow method makes use of mistake information from some non-triggering stations in earthquake catalog, and some P-wave arrivals are not included in the earthquake catalog due to discontinuous records or unclear records of the seismic phase, which induces incorrect location.
