The Discontinuity of Rockmass Chemical Weathering and Its Scientific Significance;

This paper exposes the complexities in history and historical studies via investigating the continuity and discontinuity in history,the emphasis on historical documents and use of reasonable imagination in historical studies,the limitations and the unavoidable modernity in historical works.

Life development is the integration of continuity and discontinuity.

Based on the simplification of non-continuity problem, the single fissure model and its solved condition are established , which describes the state of groundwater fluxion and water s temperature distribution.

The life education pays attention to person’s life health to grow, must guide according to the life original condition ,not only inquire about the life development’s order and regularity ,but also must pay attention to the non-continuity of the life development.

The linear displacement discontinuity model is derived from elastic displacement functions of wave,and then a nonlinear displacement discontinuity model is established by introducing the equivalent displacement hypothesis.
