A curtain of the same material depended from a copper rod and formed a sort of recess at the end of the room , while two large windows opened on the courtyard of the theater and were faced , at a distance of three yards at most , by a leprous - looking wall against which the panes cast squares of yellow light amid the surrounding darkness 帷幔也是同样的料子，吊在一根铜杆上，把屋子后边隔成一个小间。两扇宽大的窗户朝向剧院的庭院，离窗户最多三公尺远处，有一堵斑斑点点的围墙。夜色中，屋子里的灯光，透过窗户上的玻璃，射出一块块方形黄色光亮，映在那堵围墙上。
We used four different wavelength light including red light ( 750nm ) , yellow light ( 580nm ) , green light ( 560nm ) , blue light ( 400nm ) to stimulate four different groups compound eyes . then the ultrastructures of the compound eyes of each group were observed under electron microscope . the results showed the fine structure of the photoreceptor , the diameter of rhabdom , the dimension of perirhabdom vacuole , the number of pinocytotic vesicle below the microsvilli , the location of pigment granules , the emergence of lamellar bodies and lysosomes in cytoplasm , were different in different light adaptation 二、不同光照条件下复眼超微结构的变化三疣梭子蟹经过12h暗适应后，在不同波长的红光( 750nm ) ，黄光( 580nm ) ，绿光( 560nm ) ，蓝光( 400nm )照射下，其光感受器的小网膜细胞和感杆束的形态和超微结构呈现较大的区别，感杆束的形态、细胞内的胞器随不同波长光的适应而发生变化，在红光下感杆束直径最大，微绒毛排列整齐，在蓝光下感杆束直径最小，微绒毛最凌乱。
