For example, if your widest field eyepiece has a 40mm diameter field stop and you choose a decreasing increment diameter factor of 2 (which results in a 4x decrease in area size), you'll end up with eyepieces having field stop diameters of approximately 40mm, 20mm and 10mm.

例如，如果你的最广视野的目镜拥有40mm的视场光阑直径并且你选择间隔倍率为2，（导致4倍减少区域面积），你最终选择的这组目镜的视场光阑为40mm，20mm和10mm。

The application of HAZOP analysis for surface engineering construction in gas field was discussed too, combined with HAZOP analysis example for surface engineer construction in gas field was discussed too, combined with HAZOP analysis example for surface engineer preliminary design of production test in Longgang gas field.

并结合龙岗气田试采地面工程初步设计HAZOP分析实例，对HAZOP分析方法在气田地面工程建设中的应用进行了初步分析。

This paper presents a rapid inversion method for 3D apparent density based on separation and continuation of potential field. The new method is carried out in the following three steps. Firstly, the gravity field on the plane is separated by a cutting method into several parts corresponding to strata of different depth. Secondly, by the way of downward continuation, the field resulted from different strata is respectively reduced to a plane corresponding to its depth.

文中提出了一种基于位场分离与延拓的视密度快速反演方法：首先应用场分离的切割法对平面上的重力场进行不同深度层源的切割分离；然后运用大深度向下延拓方法将各层的场延拓至相应的深度；最后反演出各深度层的密度。
