基于51单片机的恒温箱控制系统，用两级三极管放大做驱动，PWM控制。初始设定的可调温度在室温到85度之间。(51 microcontroller-based incubator control system, do drive two transistor amplifier, PWM control. The initial set of adjustable at room temperature to 85 degrees.)

PuTTY是一个Telnet、SSH、rlogin、纯TCP以及串行接口连接软件。较早的版本仅支持Windows平台，在最近的版本中开始支持各类Unix平台，并打算移植至Mac OS X上。除了官方版本外，有许多第三方的团体或个人将PuTTY移植到其他平台上，像是以Symbian为基础的移动电话。PuTTY为一开放源代码软件，主要由Simon Tatham维护，使用MIT licence授权。随着Linux在服务器端应用的普及，Linux系统管理越来越依赖于远程。在各种远程登录工具中，Putty是出色的工具之一。Putty是一个免费的、Windows x86平台下的Telnet、SSH和rlogin客户端，但是功能丝毫不逊色于商业的Telnet类工具。目前最新的版本为 0.68 latest release(PuTTY is a Telnet, SSH, rlogin, pure TCP, and serial interface connection software. The earlier version supported only the Windows platform, and in recent versions began to support various Unix platforms and was intended to be ported to Mac OS X. In addition to the official version, there are many third party groups or individuals that migrate PuTTY to other platforms, such as Symbian based mobile phones. PuTTY is an open source software that is maintained primarily by Simon Tatham and licensed using the MIT licence. With the popularity of Linux applications on the server side, Linux system management is becoming more and more dependent on remote. Putty is an excellent tool for various remote login tools. Putty is a free, Telnet, SSH, Telnet, and rlogin client on the Windows X86 platform, but it is no less functional than the business class tools. The latest version is 0.68 latest release)

使用STC单片机IAP15W63S4开发的液压桥架拉拔控制系统，电路板设计12个开关量输入信号，10个开关量输出信号。 四段0-10伏模拟量输出信号。机器使用两套液压伺服控制电机，两套压紧拉拔油缸。分别由12个开关量输入信号 检测动作位置，由10个开关量输出信号控制电磁阀输出。

在一个8×8国际象棋盘上，有8个皇后，每个皇后占一格；要求皇后间不会出现相互"攻击"的现象,即不能有两个皇后处在同一行、同一列或同一对角线上。问共有多少种不同的方法。 本算法采用一维数组来进行处理。数组的下标i表示棋盘上的第i列，a[i]的值表示皇后在第i列所放的位置。如：a[1]=5，表示在棋盘的第一例的第五行放一个皇后。(8 × 8 in a chess set, there s eight, each accounting for a Queen s grid request will not be any mutual between Queen s attack phenomenon, that can not have two Queen s in the same line, the same row or the same diagonal. Asked the total number of different ways. This algorithm uses one-dimensional array to be processed. Array subscript i said i chessboard first out, a [i] value that s in the first place i listed by location. Such as: a [1] = 5, said the first cases in the chessboard of the fifth line of a Queen s release.)
