Although the accuracy in meterological forecast of tropical cyclones has been distinctly improved, it is still a difficult problem confronting masters and anti-typhoon team leaders of the companies how to steer clear of typhoon reasonably and safely in case that the actual resistance to typhoon is strong enough, the sea area wide enough, and the time permitting ; to avoid unreasonable deviation,anchoring for shelter, blindly rushing onto her path,being involved in storm area,even into the the center of typhoon; under the limitation of the condition of the sea area and time.how to take correct meassures to escape , such as navigating with wind or windward in bias angle, slowing down, anchoring, berthing alongside the warf, mooring to buoy,etc.

传统的解决办法是，将台风中心的预报位置和本船的船位点绘在《台风位置标示图》上，研究本船与台风的相对位置以及相互间动态的发展态势，考虑各种因素的影响并留有充分余地，在小比例尺海图上用几何相对运动标绘的方法作图绘算出本船应采取的避台航向。本文所讨论的就是为迅速和较为精确地解决以上点绘和相对运动标绘的问题，在考虑了各种因素的影响并留有充分余地的情况下，在全方位范围内搜索安全航向，对本船与台风的相对位置以及两者之间的动态发展态势作出预报，并给出船长最关心的、对其作出避台决策至关重要的一组数据和直观图形，帮助使用者及早制订科学合理的避抗预案，及时果断地采取正确有效的避抗措施，解决避台决策的实际问题而设计的一个计算机标绘系统。

In order to locate mined-out areas in gold mines and place a curb on its hidden hazard, through laying out two high precision gravity survey sections of the 1∶100 scale in the research area, with Canadian Scintrex Corporation′s CG-5AutoGrav gravimeter, the gravity anomaly data are measured by the high precision gravity survey method for the first time, and the inversion is made by the Euler deconvolution method to determine the collapse of the mined-out region and the stable sector.
