摘要
就微机与热球风速仪联合测速给出了减小误差的若干措施及测试系统的构成 .认为采用 1 2位分辨率的 A/D模数转换板即能满足测试系统的要求 .在热球风速仪测头的标定中 ,将电测系统看成为一个整体 ,由微机直接读数以降低系统误差 ,并给出了 1
Some methods for reducing errors are given in joint velocity measurement by using computer and heat bulb and constituens of it are introduced. It can meet the needs of measurement when the resolving power of A/D transform plate equals 12. In demarking the heat\|bulb velocity measurement head , the computer\|measurement system is taken as a whole, so the demarked data can be conveqed directly to the computer to decrease the possible error of the system. The revised curves of all 16 heat\|bulbs are given.
