为了适应农业发展对公路建设的迫切耍求,在技术力量不足和仪器昂贵、不易购置的情况下,推荐使用本文所介绍的曲线测算仪进行地方道路的测量工作。兹将测算仪某些有关事项介绍如后。理论根据主要根据三角几何学中圆与线、角与弧的原理推算求得。经多次试证确无较大误差(曲线半径在100公尺以下者准确度至公分,1000公尺以下者准确度至公寸)。
In order to meet the urgent demand of agricultural development for highway construction, it is recommended to use the curve calculator described in this article to carry out the measurement of local roads when the technical force is insufficient, the instruments are expensive and difficult to purchase. I hereby introduce some of the relevant items such as calculator. The theory is mainly based on the principle of circle and line, angle and arc in trigonometry. After many trials there is no significant error (curve radius of 100 meters below the accuracy of centimeter, 1000 meters below the accuracy of the following dimensions).
