Methods:The porcelain specimens etched for 0 to 210 s and then bonded with composite resin. After storage in 37 ℃ water for 24 h the shear bond strength was measured.Results:Unetched porcelain did not bond to composite resin. Different etching time resulted in diferent bond strength.

他们之所以能够成功的被应用于临床上，与目前在瓷与树脂粘结方面所取得的成功是分不开的，瓷与树脂产生的牢固结合力是获得成功的必由之路。

The test result showed , the friction coefficient and wear coefficient of neat novolac epoxy would decrease with the content of hardener decrease at unlubricated sliding friction condition.

对制备的无填充树脂和石墨填充树脂固化物的无润滑滑动摩擦磨损性能进行了系统的研究，获得了具有理想摩擦系数和磨损系数的复合物涂层。
