贵刊今年第一期介绍的钢球式静平衡,具有结构简单,易制造,且灵敏度高的特点。我们在制造钢球式静平衡时,首先按该文的介绍,将钢球粘结在支承座的锥孔中(原文二、第1~2行)。试验结果,静平衡不很灵敏;后我们将钢球粘结在支承的锥孔中,支承座改为平面,试验结果,灵敏度很高。我们估计原文中的支承座实系支承之误。
The first quarter of this year introduced your ball static balance, with the structure is simple, easy to manufacture, and high sensitivity characteristics. In the manufacture of steel ball static balance, we first press the introduction of the article, the steel ball is glued to the bearing seat taper hole (the original two, lines 1 to 2). Test results, the static balance is not very sensitive; after we bonded the ball in the bearing tapered bore, bearing seat to a plane, the test results, high sensitivity. We estimate that the support seat in the original text is actually supported by mistake.
