Description: 此为ZLib最新版本1.2.5。原作是用C编写的，在VC++、BC++或C++Builder中自然很容易直接使用，对于Delphi开发者，虽然Delphi自带了ZLib的移植版本(zlib.pas)，但版本为1.0.4，而且必须要使用Borland自己编译生成的zlib.dcu（当然，在完整版的光盘中包含了编译好的zlib库的.obj文件和c代码，后继版本修改了大量的bug，并较大幅度地提升了性能。
此源码为编译好适合Delphi的版本。-This is the latest version of ZLib 1.2.5. The original is written in C, in VC++, BC++ or C++ Builder is very easy to direct the use of natural, for the Delphi developer, although the transplant Delphi version comes with ZLib (zlib.pas), but version 1.0.4, and must be compiled using Borland own generated zlib.dcu (of course, in the full version of the CD-ROM contains the compiled zlib library. obj file and the c code, and subsequent versions of amended a number of bug, and more significantly enhance performance. This source code is compiled for the version of Delphi.

Description: 略简说下解密主要是靠加密后得前8个字节+密钥来运算
而前8个字节是根据随机数+启动时间运算而来
详细思路在大家看看代码应该能够看明白的
密钥任意设置 支持 中文、字母、数字、符号（可重复）
其实过程也并非复杂 看得懂的人应该感觉很简单的
运算主要利用 位异或（xor） 位取反（not）
相同内容 每次加密后的内容都不会相同 随机动态生成
加密后的内容需解密时需要保存完整字节
缺少任意位置字节都会导致解密错误（除非最尾的吧）
密钥（key）也要保持跟加密时一致
加密解密测试效果 CPU:（R）D 2.8
30000个字节（易语言升级历程.txt）
只是加密或解密中的一项的耗时
（加、解、耗时都很相邻）
密钥:abcdefg
长度:7
耗时: 0- 16 ms
密钥:abcdefghijklmnopqrhtuvwxyz1234567890~!@#$ ^&*()_+-=
长度:51
耗时: 78-125 ms
密钥越长 费时就多点 加解密key一个字符都不能错
也不会说密钥大概有部分对也能够解密部分信息
-Jane said, slightly under the encrypted decryption key is obtained through the first 8 bytes+ the key to computing
The first 8 bytes is based on random number+ start-up time from operation
For more ideas take a look at the code should be able to see to understand
Key set to support any Chinese, letters, numbers, symbols (repeatable)
In fact, the process is not complex and can read people should feel very simple
Operation mainly use bit different or (xor) bit to take anti-(not)
The same content each time the encrypted content is not dynamically generate the same random
Required to decrypt the encrypted contents of the byte when the need to preserve integrity
Bytes will result in a lack of anywhere to decrypt error (unless the end of it the most)
Key (key) must remain consistent with the encryption
Encryption and decryption test results CPU: (R) D 2.8
30,000 bytes (easy language upgrade process. Txt)
Only encrypted or decrypted in a time-consumin

Description: ■基本范围-55℃-125℃
■精度误差小于0.5℃
■LED数码直读显示
■温度高于35℃启动风扇降温，低于34℃ 停止风扇
■可以任意设定温度的上下限报警功能
本方案考虑到使用温度传感器，在单片机电路设计中，大多都是使用传感器，所以这是非常容易想到的，而温度传感器有数字和模拟之分，但使用数字温度传感器更加方便直接，因此可以采用数字温度传感器DS18B20，此传感器可以很容易直接读取被测温度值，进行转换而直接得到数字温度量，就可以满足设计要求。-■ basic range-55 ℃-125 ℃
■ precision of less than 0.5 ℃
■ LED display digital direct-reading temperature higher than 35 ℃
■ start cooling fan, the fan stops lower than 34 ℃
■ temperature can be arbitrarily set the upper and lower alarm program
Taking into account the temperature sensor, the microcontroller circuit design, most are using the sensor, so it is very easy to think, and temperature sensor with digital and analog of the points, but more convenient to use digital temperature sensor directly, it can use digital temperature sensor DS18B20, this sensor can be easily read directly measured temperature, conversion and digital temperature measurements directly, it can meet the design requirements.

of resonant circuits by 62 , allowing operation near the of
transistors. The technique leads to a fundamental oscillator operating
at 128 GHz with a power dissipation of 9 mW and a phase
