一、前言在水工模型试验中,水位和流速是两个必须测试的最基本的水力学参数。常规方法是现场逐点测试,因而测点数量受到很大限制,在一定程度上影响测试结果的精度及代表性。为此用一台APPLEⅡ微型机进行水位、流速的同步或不同步采集,以便为工程规划设计提供更多而准确的水位和流速资料,做到合理应用微机。 I. Introduction In the hydraulic model test, the water level and flow rate are the two most basic hydraulic parameters that must be tested. The conventional method is site-by-site test, so the number of test points is greatly limited, to a certain extent, the accuracy and representativeness of the test results. To do this, an APPLE II microcomputer is used to collect the water level and the flow rate simultaneously or out of sync so as to provide more and accurate water level and flow rate data for the project planning and design so that the microcomputer can be rationally used.
