ring gap

Oil control ring gap to be located 30 degrees to the left of combustion chamber recess.

控油环间隙位于燃烧室凹口的左30度.

The synthesis of tetrahydrofuran copolymerized GAP binder includes two steps: THF and ECH ( epichlorohydrin) are copolymerized with the help of catalyst ( BF3 ·+ diol) through cation ring opening copolymerization to hydroxyl terminated THF-ECH copolyethers;

四氢呋喃共聚型GAP粘合剂的合成分两个步骤：a.通过四氢呋喃（THF）和环氧氯丙烷（ECH）在BF3·加二元醇催化下的阳离子开环聚合反应合成端羟基THF－ECH共聚醚；

A gap in the A ring, also named for its discoverer, is called Encke's division.

在A环中还有一条缝, 也以其发现者命名, 称为恩克(Encke)环缝.

By this, raise some practical and effective measures to bring sealing ring function and effect into full play in many ways, such as improving superficial processing quality, choosing proper velocity in motion and sealing gap, improving O sealing ring quality and so on.

在此基础上，又从提高表面加工质量、选择适当的运动速度、密封间隙、改善O形密封圈自身质量等多个角度提出了充分发挥密封圈功能的几条切实可行的措施。
