光学设计软件zemax源码： This DLL models an nular aspheric surface as described in: "Annular surfaces in annular field systems" By Jose M. Sasian Opt. eng. 36 (12) P 3401-3401 December 1997 This surface is essentially an odd aspheric surface with an offset in the aspheric terms. The sag is given by: Z = (c*r*r) / (1+(1-((1+k)*c*c*r*r))^ 1/2 ) + a*(r-q)^2 + b*(r-q)^3 + c*(r-q)^4 + ... Note the terms a, b, c, ... have units of length to the -1, -2, -3, ... power.

1、 了解系统调用pipe()的功能和实际原理 2、 编写一段程序，使用管道实现父子进程之间的通信 a) 使用系统调用fork()创建一个子进程 b) 子进程调用函数write()向父进程发送自己的进程ID和字符串” s sending a message to parent.\n”。 c) 父进程调用函数read()通过管道读出子进程发来的消息，将消息输出屏幕，然后终止

1、 了解系统调用fork()、execl()、exit()、getpid()和waitpid()的功能和实现过程 2、 编写一段程序实现以下功能： a) 使用系统调用fork()创建两个子进程 b) 父进程重复显示字符串”parent:”，并使用函数getpid()显示自己的进程ID。 c) 两个子进程分别重复显示字符串”child:”，并使用函数getpid()显示自己的进程ID 3、 编写一段程序实现以下功能： a) 使用系统调用fork()创建一个子进程 b) 子进程显示自己的进程ID和字符串": The child is calling an exec.\n"，然后通过execl()调用系统命令ps显示当前运行的进程情况，从而更换自己的执行代码，最后调用exit()结束。 c) 父进程显示自己的进程ID和字符串” ": The parent is waiting for child to exit.\n "，然后调用waitpid()等待子进程结束，并在子进程结束后显示”The parent exit.\n

收SP下行消息 A. 启动MMSC侦听端口 在模拟器界面的右下角的"Liten Port"文本框中输入MMSC的侦听端口，这个值是为接收SP发出的下行消息提供服务的端口号，比如："8080"，按下"Start"按钮启动MMSC侦听服务。 B. 接收消息 接收的是从SP（API）发来的消息，处理后回一条响应消息。 2 模拟MMSC向SP发送上行消息 A. 选择模拟器左边界面的MessageType为“DeliverReq”； B. “Send To”文本框中输入SP的上行地址，例如http://10.164.50.29:8888； C. 在界面中选择输入其他需要的字段，然后点击“Send”按纽即可向SP上行地址发送上行消息。 3 模拟MMSC向SP发送递送报告消息 A. 选择模拟器左边界面的MessageType为“DeliverReportReq”； B. “Send To”文本框中输入SP的上行地址，例如http://10.164.50.29:8888； C. 在界面中选择输入其他需要的字段，然后点击“Send”按纽即可向SP上行地址发送递送报告消息。 4 模拟MMSC向SP发送阅读报告消息 A. 选择模拟器左边界面的MessageType为“ReadReportReq”； B. “Send To”文本框中输入SP的上行地址，例如http://10.164.50.29:8888； C. 在界面中选择输入其他需要的字段，然后点击“Send”按纽即可向SP上行地址发送阅读报告消息

acm HDOJ 1051WoodenSticks Description: There is a pile of n wooden sticks. The length and weight of each stick are known in advance. The sticks are to be processed by a woodworking machine in one by one fashion. It needs some time, called setup time, for the machine to prepare processing a stick. The setup times are associated with cleaning operations and changing tools and shapes in the machine. The setup times of the woodworking machine are given as follows: (a) The setup time for the first wooden stick is 1 minute. (b) Right after processing a stick of length l and weight w , the machine will need no setup time for a stick of length l and weight w if l<=l and w<=w . Otherwise, it will need 1 minute for setup.
