1·The laser heat treatment process and mechanism on the surface of piston ring groove were studied.

对活塞环槽表面的激光热处理工艺与机理进行了试验研究。

2·In some application, a narrow groove is cut into the piston above the top ring to serve as a heat dam to reduce the amount of heat reaching the top ring.

在一些实际结构中，一条窄槽切入顶端活塞环的上部，其作用是充当“隔热槽”以减少达到顶端活塞环的热量。

3·The ceramic treatment for the first ring groove of ZL108aluminum alloy piston was conducted with micro-arc oxidation technique.

利用微弧氧化技术对ZL 108铝合金活塞第一道环槽进行了陶瓷化处理。

4·The piston rings carried in the ring groove are of two basic types: compression rings and oil-control ring.

安装在环槽中的活塞环有两种类型：压缩环和机油环。

5·The inside surface of the ring fits in the groove on the piston.

些环的内表面和活塞上的凹槽相配合。

6·Upper and lower piston rings are arranged inside a piston gaseous ring groove, and openings on the two-piece piston rings are mutually staggered.

在一个活塞气环槽内设有上下二片活塞环，二片活塞环上的开口相互错开。

7·We analyse the influence of the elastic deformation and the surface roughness for lubricating characteristics and give a thought of cutting groove in piston ring.

分析了弹性变形、表面粗糙度对润滑性能的影响，并提出了开槽环的设想。
