The achievements achieved in the study are presented as follows : ( l ) to the distribution of construction duration of the pert network , even though every activity duration obeys normal distribution , it is failed to be proved to be in the obedience with normal distribution strictly . however , if there - are a lot of activities in a path of the pert network , for instance , more than 20 activities , without reference to the normal distributions - distribution or triangle distribution which activities duration obeys , the construction duration approximately obeys the normal distribution when the form of distribution is not partiality seriously 通过本文的研究取得的新成果有: ( 1 )对pert网络施工工期的分布,即使每一活动持续时间服从正态分布,也不能证明其严格服从正态分布,但当pert网络线路上的活动较多时,如超过20项,不论活动持续时间服从正态分布、分布,还是三角分布,当偏态不十分明显时,则工期近似服从正态分布。
They often solve the problems with two methods . the first one is disturbing and controlling the spurting water with a movable baffle - plate . the second is the proper arrangement of the sprinklers , ( such as isoceles triangle distribution , equilateral triangle distribution , square distribution , and rectangle distribution ) 喷灌的均匀度不高的问题由来已久,国内外的喷灌技术研究人员为解决该问题一般从“干扰、控制从喷嘴喷出的水舌” (利用挡水板和导流板来实现)与“合理的安排喷头的组合形式” (等腰三角形布置、等边三角形布置、正方形布置、长方形布置)上来。
In order to solve this problem , the distribution of the force was studied . with analyzing the data of ship launching , the paper educes seven typical distribution forms , include uniform distribution , sine distribution ( 1 / 2 amplitude ) , trapezoid distribution , right triangle distribution , sine distribution ( 1 / 4 amplitude ) , parabola distribution , isosceles triangle distribution 主要有七种分布形式,包括分布趋势较平缓的均匀分布形式、正弦( 1 2波形)分布形式、梯形分布形式;峰值出现在滑道最前端的直角三角形分布、正弦( 1 4波形)分布、抛物线形分布;还有峰值出现在分布区域中间的等腰三角形分布。
