对象链接与嵌入技术在产品测试输出中的应用

在某型产品研制过程中,其性能指标需要进行全面测试。过去,测试结果通常采用手工填写方式,但是存在效率低、费时费力、容易出错等问题。本研究采用对象链接与嵌入技术,在VC++平台下操作Excel表格,实现产品测试结果的批量输出和图表绘制功能,大幅度提升某型产品测试数据输出的准确性,提高产品测试数据分析及交付效率。

Properties analysis of a large flow-rate safety valve test device

In order to solve the problem of property test of large flow-rate safety, the property parameter of safety valve test system was analyzed, and a device for property oflarge flow-rate safety valve test was designed.The device used accumulators as power source and a united function cylinder, which can realized the large flow-rate output for the test system.Analyzed the test data and made a particular research on the test device by testing different flow-rate safety valves;it verifies that the test device can be used tode-sign larger flow-rate safety valve test system and can make the flow-rate test and analysis and dynamic characteristics for the large-flow safety valve.
