斜航测流成果的好坏,经我们试验发现与以下两点有很密切的关系:(1)测船行速的均匀问题;(2)对轴角的掌握问题。为了解决这些问题,一九五三年经我站同志们研究,在双舟测船上安装了一种铁质的拨水轮,由二人搅动拨水轮,每秒行1.5公尺,比用船槁撑着前进速度就均匀得多了。但对正确地掌握轴角问题当时未得到解决,仍采取开始时对好角度估计横渡对岸的办法。今年经同志 The result of oblique flight flow measurement is good or bad, and it is found by our experiment that there is a close relationship between the following two points: (1) the uniform problem of the line speed of the ship; and (2) the problem of grasping the shaft angle. In order to solve these problems, in 1953, as my comrades studied, we installed an iron wheel on a double-boat survey ship. The two people stirred the wheel at a speed of 1.5 meters per second The speed of propping forward is much more uniform. However, the correct understanding of the issue of shaft angle was not resolved at that time and the measure taken at the beginning of a good angle to estimate the other side of the river was taken.
