We first show that this problem can be plotting"functions to solve this problem and get an appropriate solution(about 3. 82mm). As to the second problem, we proved 3 theo- rems, which helps to draw the shade on the test screen. We developed two different methods to finish the picture(dot-by-dot and line by-line). We discussed the third problem frorn 3 different ways. Finally we proved that every proximity hypothesis we made is approp- Keywords: continuous modeling; maximum 上接64页) The Optimising Designal Model of Linear Luminaire of Motor Light ZHANG Zuo-qi, HAN Fang, CHEN Yan-zhou Adrisor: CHEN Si-hua (Wuhan Ur Abstract: In this paper, the law how the number of valid points of incidence changes with different points on the linear luminaire is studied firstly, then a rational division is given. On the bagis of that, an optimising mathmatical model is established; with the method of numberical calculation and diagrammatic analysis, the optimal result, 1=3. 8mm and Pin 7210, are adquired. Acoording to the result, the figure of area lighted by reflective rays can be defined easily with the help of software Matlab. The model is simple and can also be used in other relative domains Keywords: the optimising designal model, linear luminaire, the optimal length, the minimum power o1995-2004 Tsinghua Tongfang Optical Disc Co, Lid.
