前言影剧院的视线设计中地面坡度计算,有几种计算方法,其中相似三角形数解法是较普遍采用的一种方法。此种方法的计算必需从第一点开始,由前向后逐点计算,最后才能求出总的升高值。如果在演算过程中间产生差错,则以后各点均错。为了避免这种现象的出现,本文对用相似三角形数解法计算地面坡度时设想了一种新的应用方法。此方法的特点是:利用各种图形求出各种基本数据,再根据其数据有系统地列出基本计算公式,式中之各已知数据可以逐步地在图形上找出,立即写进公式内,精心求出第一个公式的升高值,将此升高值再代人第二个公式中求出第二个升高值,以此类推,即可准确
Foreword There are several calculation methods for calculating the slope of the ground in the design of the line of sight of the theater, among which the method of number of similar triangles is a method commonly used. The calculation of this method must start from the first point, calculate from the front to the back point by point, and finally the total rise value can be calculated. If an error occurs in the middle of the calculation process, all subsequent points will be wrong. In order to avoid the appearance of this phenomenon, this paper conceives a new application method when calculating the slope of the ground using the similar triangle number solution method. This method is characterized by: using a variety of graphics to find a variety of basic data, and then based on the data are systematically listed basic calculation formulas, where the known data in the formula can be gradually found on the graph, immediately written into the formula Internally, carefully evaluate the rise of the first formula, find the second rise value in the second formula of this rise, and so on, you can accurately
