求助：请问这句怎么翻译？谢谢

the product of the pressure P multiplied by the inter-electrode spacing D is to the left of the minimum of the Paschen curve.
我翻成：压力P和电极间距D的乘积处于帕邢曲线的最小值的左端。但是感觉不对，高手指点一下吧。
另一句可以作为参考：it is generally admitted that  a contactor which has a product pressure * spacing to the left of the mimimum of Paschen curve is able to cut only an alternating current which is being cancelled.
通常认为压力乘以电极间距的乘积处于帕邢曲线的最小值的左端的接触器只能切断正被抵消的交流电流

to的意思应该为：趋向于；接近
以下的供参考：
压力P和电极间距D的乘积接近帕邢曲线的最小值。

谢谢，刚才写错了，在minimum 前还有left！
