中国2000-2015年的186组 CPI 指数所体现的变化规律，可以用通道原理来描述。通道类似于交通图中的道路，依据切比雪夫最佳逼近原理，以 CPI 函数为中心线，以极小化最大正负误差为边界线，包含了所有的 CPI 数据，是一条具有最大安全范围意义的数据通道。假设端点数据是建立在零误差基础上的最大权重数据，未来短期内 CPI 指数的变化不存在突变，或存在突变但其误差不大于通道内的最大正负误差，则通道的延伸可以预测未来 CPI 指数的变化，以及变化的波动范围。介绍了 CPI 通道的基本原理与方法、适用范围、判别法则、具体算法等。通过多个数据处理实例，说明了直线通道具有简单易懂、直观性强、计算方便、适用范围广、符合性较好等特点，验证了未来短期 CPI 指数变化基本是可知与可控的。

The 186 sets of CPI index data from 2000 to 201 5 years in China reflected some rules,which can be described by Channel principle and the corresponding method.Channel is a data channel with the largest security sense,which based on Chebyshev approximation theory,to the CPI function as its center line,to minimize the maximum positive and negative error as its boundary line,and contains all the CPI data.Assuming that the endpoint data is the largest weight data based on zero error, there is no mutation of CPI index in the short term,or mutation but the error is less than channel's maximum positive and nega-tive error,then the future CPI index can be given by the channel through the forecast value and fluctuation value.This article in-troduced the CPI channel principle and its method,the applicable scope,the judging rules,the concrete algorithm,etc.Through some examples of data processing,this paper shows that the straight line channel is easy to understand,intuitively simple and strong,convenient in the computation,broad in the applicable scope,good in the compliance,and also verifies that the scope of future short-term changes in the CPI index is knowable and controllable.
