台架

The bench test results indicated that the metering quality of the dibbler was increased significantly after improvement.

架试验结果表明，穴播器经改进后对棉种的播种精度有提高。

In this paper, we utilize current equipments such as dynameter and specific fuel consumption detector, and design a set of engine test bench platform based on P89C668.

根据发架试验测试平的基本要求,充利用测功、油耗仪等原有设备,开发基于P89C668的发架试验测试平,实现显示、打印、控制和通讯等功能。
