说明: 移动电话主要采用频率复用,但分配给移动电话的频段很少,远不能满足用户的需要。
因此就提出将地区划分成小区,称为蜂窝(Cell),每个蜂窝内使用一组频率,相隔一段距离后,相同的频率又可重复使用。
(The main use of mobile phone frequency reuse, but allocated to the small-band mobile phone, far from being able to meet the needs of users. Therefore proposed to be divided into residential areas, known as cellular (Cell), each use a set of cellular frequencies, separated by some distance, the same frequency can be reused.)

说明: C语言趣味程序百例精解,是PDF格式。里面有很多趣味的例子,大大小小的算法都有,可谓是算法的经典。这个是学习算法的好资料,在学习中找到趣味,完全不同于其他资料的算法枯燥无味(C language program 100 cases of sperm interesting solution is in PDF format. There are many interesting examples of both large and small algorithm, the algorithm can be described as classic. This is a learning algorithm is good information, in learning to find interesting information is completely different from other algorithms dull)

地磅测试程序,将字符串发送到指定COM口,基于VB写的地磅仪表数据读取工具源码,包括调用了一个仪表通信采集工具、上海耀华、托利多等大众仪表,有一定的参考价值。
设置Com1为通信端口,设置通信端口参数 9600赫兹、偶校验、7个数据位、1个停止位.(这里需要进一步说明的是tting="BBBB,P,D,S,含义是:B:Baud Rate(波特率);P:Parity(奇偶);D:Data Bit;S:Stop Bit)。
.InBufferSize = 40 设置缓冲区接收数据为40字节
.InputLen = 1 设置Input一次从接收缓冲读取字节数为1
.RThreshold = 1 设置接收一个字节就产生OnComm事件。
Timer可以计算从子夜到现在所经过的秒数,在Microsoft Windows中,Timer函数可以返回一秒的小数部分。(Weighbridge test program, the string will be sent to the specified COM port, source-based reading tool written in VB weighbridge instrumentation data, including calling an instrument of communication collection tools, Shanghai Yaohua, Toledo and other public instruments, there is a certain reference value.
Set Com1 communications port, set the communications port parameters 9600 Hz, even parity, 7 data bits, 1 stop bit (It should be further noted that tting = "BBBB, P, D, S, meaning:. B: baud Rate (baud rate) P: Parity (parity) D: Data Bit S: Stop Bit).
. InBufferSize = 40 is set to receive data buffer is 40 bytes
. InputLen = number Set Input once read from the receive buffer byte 1 of 1
. RThreshold = 1 is set to receive a byte generated OnComm event.
Timer can be calculated from midnight to now the number of seconds elapsed, in Microsoft Windows, Timer function can return a decimal fraction of a second.)
