一、引言“游轮的游动条件与安全”一文(见《煤矿安全》,1984,№8,24～26)的分析方法本人认为有些部分值得商榷,因为:第一,采用游轮后,固定天轮的设置点 O 不能作为计算α角的依据;第二,α_1为游轮的入绳偏角,与α互为内错角,即α=α_1,β迟(图1中的α＇)为游轮的出绳偏角,与α是两个不在同一平面的空间角度,两者之间没有几 I. INTRODUCTION THE ANALYSIS METHOD OF “HYDROLOGY CONDITION AND SAFETY OF A CRUISE” (See “Coal Mine Safety”, 1984, № 8,24 ~ 26) In my opinion, there are some parts that are open to question because: First, after a cruise ship is used, The set point O of the wheel can not be used as the basis for calculating the angle α; secondly, α_1 is the angle of arrival of the cruise line, and α is the internal angle with each other, that is, α = α_1, β is late (α ’ Out of the rope declination, and α are two are not in the same plane space angle, there is not much between the two
