proper channel

In this way, the micro-angle with single step comes true. With the principle of push-and-pull relay movement which is improved from the principle of inchworm motion and proper four-channel driving signals, PZT platform can move continuously and smoothly.

根据尺蠖运动（Inchworm motion）原理，采用推&拉接力运动原理，配以适当的四路驱动信号，使压电电动机实现连续平稳的转动。

Firstly, the autoregressive ( AR) models with proper order are used to approximate the time variation of the coefficients of wireless time-varying channel.

我们使用适当阶次的自回归（AR，autoregressive）模型去近似时变瑞利衰落信道，通过一个训练序列的训练过程来建立AR模型参数和获得初始的观测。

The right target markets are chose according to the different product position and the proper channel strategies are selected by the enterprises' strength.

依据不同的产品定位，选定恰当的目标市场；依据企业实力，选择适当的渠道策略。

The spatio-temporal profile of sample plug can be well controlled in the analysis channel by switching virtual gate in a proper mode and timing.

通过控制虚拟门的打开方式和时机，可以控制样品注入分析通道的时空分布。

Another work in this project is to develop a proper space-filling curve to map the speech signal samples into the channel space directly.

另一项主要工作是筛选合适的空间映射曲线，使语音采样信号能够直接映射到信道中去。
