说明：  The 1-Wire Software Development Kit (SDK) for Windows is divided into 3 sections, each representing a unique Applications Programmer Interface (API). The first section focuses on the 1-Wire .NET J# libraries called OW.NET API. The second section focuses on an API that is essentially a port of the OW.NET "DSPortAdapter" object to C#, called the Compact.NET API.The third section is the TMEX API. This is a basic low-level, natively-compiled API that performs 1-Wire communication and file structure primitives.

此规范定义了统一建模语言（UML），修订版2。 UML的目标是提供系统 与分析工具，设计和实施基于软件的系统架构师，软件工程师，软件开发人员以及建模业务和类似的过程(This specification defines the Unified Modeling Language (UML), revision 2. The objective of UML is to provide system architects, software engineers, and software developers with tools for analysis, design, and implementation of software-based systems as well as for modeling business and similar processes)

键是一种标准零件,通常用来实现轴与轮毂之间的周向固定以传递转矩，有的还能实现轴上零件的轴向固定或轴向滑动导向。在键连接设计时，间的高度和宽度根据轴的直径d选取，而键长L则根据轴上零件轮毂宽度B而定，通常L=B-（5—10）mm。键的尺寸确定后，再进行强度校核。而为了保证绝对安全，键的尺寸取值往往都趋于保守，所选键的尺寸大。本程序采用优化设计方法，在满足强度要求的前提下求出键的最小结构尺寸，证明键宽b和键高h的取值可以小于标准值。(Key is a standard part, often used to achieve between shaft and hub to transfer torque to a fixed week, and some can achieve a fixed axis or axial parts of the axial sliding direction. Key connection in the design, height and width between the shaft diameter d according to selection, and the bond length L is based on the width of the wheel shaft parts B and, typically L = B-(5-10) mm. Key size is confirmed, then strength check. In order to guarantee absolute security, key size values ??are often conservative, the size of the selected key to big. The program uses optimization methods to meet the strength requirements of the derived key premise of the minimum structure size, proved key width b and height h of the key values ??can be less than the standard value.)

说明：  J1939是SAE（美国汽车协会）定义的基于CAN总线的规范，目的是解决不同发动机厂商、不同ECU厂商的兼容性问题。一般运用于大型车辆。(J1939 is a specification based on CAN bus defined by SAE (American Automobile Association), aiming at solving the compatibility problem of different engine manufacturers and different ECU manufacturers. Generally used in large vehicles.)
