| 5. | It can be concluded that the performance differences between the plate membrane and the hollow fiber membrane can be attribute to difference of the stresses in the membranes when they were under pressure and the difference of the strain caused in the membrane , besides the possible reason that the surface curvature difference between a plate substrate and a hollow fiber one may cause structure difference in the dense functional layer when coating . the stresses in a hollow fiber composite membrane under an outside pressure are quite different from that in a plate one in that they exert on the hollow fiber in both the radial and circular directions , and the compress strain of the hollow fiber is thus much more complex , which may cause the top layer crinkle and a decreased salt rejection
分析认为造成平板复合膜( )和中空纤维复合膜( )性能差异的主要原因，除了平板基膜与中空纤维基膜因表面曲率不同可能引起在涂覆时形成的致密功能层结构上的差异之外，由于中空纤维膜受外压时，膜内部承受的应力形式与平板膜不同，会同时在径向(膜厚度方向)和环向(膜面内方向)两个方向产生压应力，因此，所发生的形变也较为复杂，可能造成表面复合层的起皱或脱落，引起脱盐率下降。 |

| 8. | This means that the dielectric property changes with height and allows a slight increase in the speed of a radio wave as we move upwards through the atmosphere . this in turn means that if a radio wave moves away from the earth at an angle less than 90 degrees , then the upper part of the wave travels faster than the lower part . therefore even under normal conditions this can in effect bend , or refract , the wave back down to earth
其中一种显著的现象是：在一定的气象条件下，在大气边界层尤其是在近地层中传播的电磁波，受大气折射的影响，其传播轨迹弯向地面，当曲率超过地球表面曲率时，电磁波会部分地被陷获在一定厚度的大气薄层内，就好像电磁波在金属波导管中传播一样，称为大气波导传播，形成波导传播的大气薄层称为大气波导层。 |
