When the pad area is greater than 66 percent of the aperture wall surface area, the probability of achieving efficient paste transfer is increased.

当焊盘面积大于孔壁表面积的66%。提高锡膏有效转移的可能性。

A completion component fabricated as a short section of heavy wall tubular with a machined internal surface that provides a seal area and a locking profile.

一种完井部件。它是一段厚壁短管，其内表面经过机加工，于是提供了一个密封区域和一个锁紧的型面。

Only a small portion of their surface is actually contacting the cylinder wall. The ring area that does contact the cylinder wears down the roughness of the honing pattern on the cylinder walls.

只有一小部分表面接触到了缸壁上，接触到缸壁上的部分磨损其对应的缸壁上的珩磨粗糙度。

Normally such forces are negligible, but the setae, with their spatula-like tips, maximise the surface area in contact with the wall.
