摘　　要：讨论了两列光波发生干涉现象的理想化条件和在实验中能否观察到干涉现象发生的操作性条件,推导了各种情况下的理论公式。从工程应用的角度出发,研究了检测仪器的响应时间T和光强分辨能力对观察光的干涉现象的影响,提出了观察光的干涉现象的第四个必要条件,对在各种情况下应用光的干涉现象有一定的指导作用。This text discussed two light waves to take place the idealization condition of interference phenomenon and can observe an operability condition that interfere with phenomenon＇s occurrence in the experiment,deducing under various circumstance of theories formula. The angle applied from the engineering sets out, this text studied an examination instrument of respond to time T and light strong distinguish an ability bare to the observation of interference phenomenon of influence,put forward ob- servation light of interference phenomenon of the fourth essential condition,to under the various con- dition the application bare interference phenomenon contain certain instruction function.
