Some geologists wondered whether the absence of friction-generated heat could be explained by the kinds of rock composing the fault.(一些地质学家想知道，是否可以用构成断层的岩石来解释没有摩擦产生的热量。)
Prior to 1965 geologists assumed that the two giant rock plates meeting at the San Andreas Fault generate heat through friction as they grind past each otherd.(1965年以前，地质学家认为，两个巨大的岩石板块在圣安德烈亚斯断层上相遇，通过摩擦产生热量。)
If, however, there's so much friction at home that it interferes with your academic work, you might want to consider sharing an apartment with one or more friends.(然而，如果家里有太多摩擦，干扰了你的学业，你可能得考虑和一个或多个朋友合租一套公寓。)
The legs, which are slightly curved with tiny hooks on the tips of their feet to provide enough friction to enable movement in a slippery environment.(它们的腿有点弯曲，脚尖上有小钩，提供足够的摩擦力，使它们能在湿滑的环境中活动。)
Under normal conditions, rocks composed of clay produce far less friction than do other rock types.(在正常情况下，由粘土组成的岩石产生的摩擦要比其他类型的岩石小得多。)
Sara sensed that there had been friction between her children.(萨拉感觉到她的孩子们中间出现了摩擦。)
Friction ACTS on moving bodies and brings them to a stop.(摩擦力作用于运动着的物体，并使其停止。)
Friction between the glacier and bedrock is reduced.(冰川和基岩之间的摩擦减少了。)
Friction marks indicated that they did, indeed, once form part of a necklace or bracelet.(摩擦痕迹显示他们曾经是项链或手镯的一部分。)
