摘要
计算和实验结果证明,以连续流出的自来水通过沉降筒外套,可以满足标准规定的恒温条件的要求。着重讨论KCT—1颗粒沉积天平的平衡点、感量、灵敏度及平衡速度的调试方法,并列举引起测定误差的多种因素及其图形变化。最后论述颗粒沉积天平稳定性的评定方法。
The results of calculation and experiments prove that continuous flowing water through outside of precipitation tube can meet the requirement on constant temperature stipulated in standards. The test methods on balance point, sense of weight, sensitivity, and balancing speed of KCT—1 particle precipitation scaleare mainly discussed and the various factors causing measuring errors and changes of their diagrams are shown in the paper. The evaluation method on stability of the particle precipitation scale is finally described.
