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.

THIS is really two books in one: a tutorial and a reference manual for JDBC, the application programming interface that makes it possible for programmers to access databases from Java. The goal is to be useful to a wide range of readers, from database novices to database experts. Therefore, we have arranged the book so that information needed only by experts is separated out from the basic material. We hope that driver developers as well as application programmers and MIS administrators will find what they need. Because different sections are aimed at different audiences, we expect that few people will read every page. We have sometimes duplicated explanations in an effort to make reading easier for those who do not read all sections. This book will be most helpful to those who have some knowledge of the Java programming language and SQL (Structured Query Language), but one doesn t need to be an expert in either to understand the basic concepts presented here.

本教程详细审查了袖珍版 Java 2 平台 (J2ME),它主要面向在 Java 编程及面向对象设计与开发方面有深厚背景的中级开发者。 您可以首先了解 J2ME 的背景并研究 J2ME 的配置和简表。随后,逐步建立您的开发环境,用于开发 J2ME 应用程序。 本教程将向您介绍一些课题如 K 虚拟机 (KVM),和 KJava API -- 用于关联连接有限设备配置 (CLDC) 和使用 CLDC 的移动信息设备简表。之后您将构造一个简单的应用程序来看看您能用 J2ME 做些什么。您将使用 CLDC 和 KJava 开发一个基本绘图应用程序以及一个小型 MIDP 应用程序。

Shamir秘密分享与恢复算法的VC++程序,主要是使用平面上k点可以决定k-1次方的多项式,以k点为门槛值,应用Lagrange多项式插入方法的技术,回复原多项式,再得出主密钥。输入大数长度和份数可自行定义(默认是270位和不超过20份)。
