Then the light intensity transmission of polarizing prisms with the incidence of random spatial light beam is studied. Both experimental and theoretical results indicate that the light intensity transmission of air-spaced polarizing prisms are affected more by the change of random spatial incident angle than dielectric-spaced polarizing prisms.

结果表明：胶合层间的多光束干涉对棱镜光强透射比的影响不可忽略，对于空气隙型偏光棱镜，由于空气隙间多光束干涉的影响，光强透射比随任意角度变化较大，而用胶合介质胶合的棱镜，其透射比对空间入射角不是很敏感。

The main reason why quarter-sawn board of Birch had smaller dry compressing shear strength than flat-sawn board of Birch in normal conditions was that Birch had different shear strength to the grain between quarter-sawn board and flat-sawn board. Meanwhile xylary rays in flat-sawn board were transversely cut and left a lot of pores in the flat-sawn board, so adhesive can enter these pores and turn into adhesive nail. While these pores provided a kind of tunnel for water, so cause this phenomenon that wet compressing shear strength of flat-sawn board of Birch was smaller than that of quarter-sawn board of Birch. The possible reason why quarter-sawn board of Oak had greater dry compressing shear strength than flat-sawn board of Oak in normal conditions was that ratio of springwood on quarter-sawn board and flat-sawn board was different.

造成柞木径切板的常态压缩剪切强度比弦切板的常态压缩剪切强度大的主要原因是，在径切板和弦切板上早材胶接的比例不同，径切板的胶合强度试件上早材胶接的比例相对少，而弦切板的胶合强度试件上早材胶接的比例比径切板的胶合强度试件上早材胶接的比例相对大，由于早晚材胶接过程中强度决定于早材，这部分胶接强度比较低，这就使得柞木径切板的常态压缩剪切强度比弦切板的大；同时在柞木弦径面胶接过程中由于实际胶接面积的不同也能造成弦径面上API胶粘剂与之形成的化学键的数量不同，这也是造成柞木径切板的常态压缩剪切强度比弦切板的大的原因之一。

The abrupt change in temperature is one of the main characteristics in scuffing. Studies have showed that friction pair temperature plays an important role in scuffing.

温度突变是胶合发生的主要特征之一，有关研究表明摩擦副温度对胶合发生起着重要作用，因此，从摩擦副的温度来着手研究胶合现象是胶合研究领域的一个重要方向。
