光學(xué)設(shè)計(jì)軟件zemax源碼: 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.

本教程詳細(xì)審查了袖珍版 Java 2 平臺(tái) (J2ME),它主要面向在 Java 編程及面向?qū)ο笤O(shè)計(jì)與開發(fā)方面有深厚背景的中級(jí)開發(fā)者。 您可以首先了解 J2ME 的背景并研究 J2ME 的配置和簡(jiǎn)表。隨后,逐步建立您的開發(fā)環(huán)境,用于開發(fā) J2ME 應(yīng)用程序。 本教程將向您介紹一些課題如 K 虛擬機(jī) (KVM),和 KJava API -- 用于關(guān)聯(lián)連接有限設(shè)備配置 (CLDC) 和使用 CLDC 的移動(dòng)信息設(shè)備簡(jiǎn)表。之后您將構(gòu)造一個(gè)簡(jiǎn)單的應(yīng)用程序來(lái)看看您能用 J2ME 做些什么。您將使用 CLDC 和 KJava 開發(fā)一個(gè)基本繪圖應(yīng)用程序以及一個(gè)小型 MIDP 應(yīng)用程序。
