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。

Both the scattering and rheological results indicated that the phenomenon similar to"double cloud point", which has been found along the vorticity direction by previous studies, could be also observed in the velocity direction, which confirms the prediction of the above theory that the polymer blend will exhibit anisotropical complex phase diagram under shear. It's also found that the mixing along vorticity direction was reduced by weak shear but enhanced by strong shear. In addition, the more remarkable the molecular weight differences between components, the more prominent the shift of the apparent phase boundary along vorticity direction.

除了以往研究发现涡流方向存在&双浊点&现象以外在，本文的光散射和流变测试均显示，剪切场下体系在流动方向上也出现了类似&双浊点&的现象，证实了上述理论模型关于剪切场会导致二元高聚物共混体系出现各向异性的复杂表观相图（例如Miscibility Gap现象）的预测；同时发现弱剪切会导致体系涡流方向上的相容性减小，而强剪切则在该方向上增强相容性；另外，两组分分子量的差异越大，表观相界的移动越显著。
