On Plans of Ancient Greek and Roman Theater and Amphitheater through the Arangement of Passage and Audience seat

从通道和观众席的排列角度对古希腊罗马剧场和圆形剧场的规划进行了分析，得出以下结论：1.通道格局、阶梯通道和水平通道形成的观众席面积，在不同时期和不同城市之间没有变化。阶梯通道和水平通道形成的观众席面积主要在40m^2至140m^2(剧场)或60m^2至200m^2(圆形剧场)之间。观众座椅的面积是对称排列的，但阶梯通道和水平通道形成的所有部分的面积通常不同。值得注意的是，大小部分之间的差异并不是很大，通常在20米^2.4以下。观众席下方有一条走廊，面积约为140m^2(剧院)或170m^2(露天剧场)。

Analisysing the plans of Ancient Greek and Roman theater and Amphitheater from the point of view of the arrengemnts of passages and audience seats, we got the following resualts :1. There is not change through the period nor between the various cities on the patern of passage, area of the audience seat formed by stepped passage and horizontal one.2. The area of the audience seat formed by stepped passage and horizontal one is mainly between 40 m^2 and 140m^2 (in the case of theater) or 60 m^2 and 200m^2 (in the case of amphitheater).3. The area of the audience seat is symmetrically arranged, but the area of all part formed by stepped passage and horizontal one usually is not same. It is worth noticing that the difference between the large part and small one is not so large, usually under 20m^2.4. One corridor under the audience seat covers the area of c. 140m^2 audience seat (in the case of theater) or c. 170 m^2 (in the case of amphitheater).
