说明：   这是一个用8051F330编写的测温程序， 用18B20实现测量温度，并通过PC机的串口显示出来。硬件要求是开发板一块，测试温度的蕊片，串口和电脑。经实验，效果还可以。
(This is a measurement used 8051F330 prepared procedures for measuring temperature using 18B20 achieve and, through PC-Serial displayed. Hardware requirement is a development board, test the temperature of chips, and computer serial port. After the experiment, the effect can also be.)
