「鋼尺溫度改正尺」創造的起始,是在五二年春下游滯洪區测量的时候,感到拉导线的计算改正工作甚为繁杂,大家都在想辦法將它簡化,我在起初的想法,是如何能将钢尺的胀缩,在量距時随即自動的改正;因之聯想到改正的因素有溫度及改正距离;就想到利用一個特製的温度計,使其溫度 The beginning of the creation of the “steel ruler temperature correction ruler” started with the calculation of the spring-loaded detention basin in the spring of May 2 and found that the computation of the pull wire was very complicated and that everyone was trying to simplify it. From my initial thoughts, How can the expansion and contraction of the steel ruler, then the amount of time when the automatic correction; so think of the correction factors have temperature and correction distance; Think of the use of a special thermometer, the temperature
