本文讨论了在平行弹簧运动中决定运动精度的主要因素--动平台的俯仰（角倾）。作为俯仰的主要原因，考虑了以下因素：（1）结构的不精确性，例如两个弹簧的自由长度的不相等和两个弹簧的分离的不相等，以及（2）驱动平台的高度。理论分析了这些因素对音高的影响，并进行了实验验证分析的有效性。结果表明，通过适当选择驱动点，可以消除驱动条件引起的俯仰。通过调节动平台的长度，可以消除由于两个弹簧间距不相等而产生的俯仰。描述了一个可变长度的移动平台，这是设计用于此目的，包括。
This paper discusses the pitch (angular tilt) of a moving platform, which is the main factor to determine the accuracy of motion in parallel spring movements. As major causes of the pitch the following factors are considered : (1) inaccuracies of construction such as the inequality in free lengths of the two springs and the inequality in separation of the two springs, and (2) the height at which to drive the platform. The theoretical analyses of the effects of these factors on the pitch, and the experiments conducted to verify the validity of the analyses, are presented. It is shown that the pitch due to the driving condition can be eliminated by proper selection of the driving point. It is also shown that the pitch due to the inequality in separation of the two springs can be eliminated by adjusting the length of a moving platform. Description of a variable-length moving platform, which was devised for this purpose, is included.
