(一) 引言於「在動平衡工作中,調整物之轉速對震幅及擺動相角之影響」一文內,作者在第五節重要聲明中曾提及,對穩妥確定調整物偏重之方位,只利用β這個相角是不夠準確的。此外,還有一個重要關係與β共同來决定調整物偏重的地位。在本文內我們便要來作這個補充,仍請大家指正。 (A) Introduction In his article “Important Volatility and Vibrating Angle” in the section entitled “The Effect of Speed ​​of Adjustment on the Amplitude and Oscillation Phase in Dynamic Balance Work”, the author mentioned in the important statement in section V that for the purpose of properly determining the orientation of the adjustment, It is not accurate enough to use only the phase angle β. In addition, there is an important relationship with β to determine the weight of the regulator. In this article, we will come to make this supplement. Still, please correct me.
