Where we began to come really close together again, in the late 60s, and gradually working toward this point, it seems to me, was when Allen began to take a deep interest in Oriental thought and then in Buddhism which added another dimension to our levels of agreement; and later through Allen's influence, Lawrence began to draw toward that; and from another angle, Michael and I after the lapse of some years of contact, found our heads very much in the same place, and it's very curious and interesting now; and Lawrence went off in a very political direction for awhile, which none of us had any objection with, except that wasn't my main focus.

1960年代后期，我们又再次很接近，对我而言，是逐渐走到了一起，艾伦开始对东方思想非常感兴趣，然后是佛教让我们更加紧密；后来因为艾伦的影响，劳伦斯也加入了进来；另一方面，麦克与我失去联系若干年后，再次相逢时，发现原来殊途同归，这现在看来真的很奇怪，也很有意思；劳伦斯后来为政治目的离开了一阵子，我们没人反对，当然这不是我们的关注所在。

T he contact angle of the films with SiO 2 ratio of 6%～13% decreases to 2° duri ng a 30 min UV irradiation,and keeps lower than 6° for 5 days without UV irr adiation.

The frictional heat energy was concentrated on the thermal effect layer with the thickness of 4 mm, The temperature gradient of contact surface is the highest, and decreased rapidly with the radius direction of the lining's groove. The temperature gradient and TEL's thickness increased with the increasing of the sliding speed. The temperature decreased rapidly with the radius direction and also with the increasing of center angle of the lining's groove. The sliding speed and distance are obtained under two sliding conditions when the lining fails, which supply the theoretical basis with the antislip design of friction hoist.
