dma functions

The principles of DMA and functions of instruments are detailed, Somestudies on polymer materials by using DMA are also described.

本文详细阐述了动态力学各种方法的原理及各种仪器的功能；并描述了动态力学分析在高分子材料研究中的应用。

The system functions include real time read outs of the physical data through the DMA/ CBLT, preliminary assembling and processing of data, transmission of data to the readout PC through the network, and interfacing with the run-control system.

该系统实现了以DMA/CBLT方式实时读出数据、对数据进行必要的组装和处理、通过网络将组装好的数据发送给读出PC等功能，并且实现了与运行控制系统的接口。

Before getting into the details of the main program, I'll explore the DMA utility functions.

在深入介绍主程序细节之前，我要先来探讨一下DMA实用函数。
