Compared with previous references [68] and Chapter 3, the relationships between viscosity solutions and lower semicontinuous solutions to QVI are further discussed in this chapter.

而且在这一章中，比[68]和第三章更进一步地讨论了这类拟变分不等式的下半连续解与拟变分不等式的粘性解之间的关系。

It can be concluded that the periodic variation of tidal range and water level has both typical semidiurnal and diurnal and semi-monthly period of tide, and 64.8 d period of river runoff, which indicates that water level of the Zhujiang Delta is controlled by tide and river flow.

不同河段潮差及各分潮波振幅与径流量的大小具有明显的反相关关系，径流量越大，潮差越小，三水站潮差随流量以-0 0002的速度减小，网河区下游河段则减小得较慢。上游径流量越大，因克服径流的阻碍作用而消耗的能量越大，潮汐作用强度迅速减弱，各分潮潮波振幅和潮差沿程减小越快。
