A passive optical network (PON) is a point-to-multipoint, fiber to the premises network architecture in which unpowered optical splitters are used to enable a single optical fiber to serve multiple premises, typically 32-128. A PON consists of an Optical Line Termination (OLT) at the service provider s central office and a number of Optical Network Units (ONUs) near End users. A PON configuration reduces the amount of fiber and central office equipment required compared with point to point architectures

selects the mux channel and configures the MAX197 for second write pulse, written with ACQMOD = 0, termi- either unipolar or bipolar input range. A write pulse (WR nates acquisition and starts conversion on WR°Os risin + CS) can either start an acquisition interval or initiate a edge (Figure 6). However, if the second control byte combined acquisition plus conversion. The sampling contains ACQMOD = 1, an indefinite acquisition interval interval occurs at the End of the acquisition interval. is restarted. The ACQMOD bit in the input control byte offer

ABC_FDTD_Die(T) Implements simulation of a Gaussian Pulse over T time steps. ABC are for free space. If boundaries are in the Dielectric medium then the ABC fail. Dielectric medium begin and End can be specified with the code

词法分析 1 试验目的 设计,编制并调试一个此法分析程序,加深对此法分原理的理解. 2 试验要求 1)待分析的简单语言的词法 * 关键字: begin if then while do End 所有关键字都是小写. 2)运算符和界符: : = + * - / < <= <> > >= = ( ) # 3)其他单词是标识符(ID)和整数型常数(NUM),通过一下正规式定义: ID=letter (letter|digit)* NUM=digit digit* 4)空格由空白,制表符和换行符组成,空格一般用来分隔ID,NUM,运算符,界符和关键字,此法分析阶段通常被忽略. 3 各种单词符号对应的种别码如表所示

编了个简单的游戏，模仿经典游戏俄罗斯方块。左右方向键控制方块的水平位置，上方向键旋转方块，End键水平翻转之。有简单的积分功能，并能根据得分多少调整游戏难度，即方块下落速度。
