    3 The following are same numerical experiments as before. As you can see, second order scheme is more accurate also more spurious. If TVD principle is not applied to MUSCL-Hancock second order method, the spurious effect will be more severe.

    55When I was writing this program, I did not follow the book exactly, one will find the problem if he(she) apply the method mentioned in book to the second test. To be more specific, I made some modification to the slope limiter, but it become very complicated. A more attractive method is Adaptive Primitive Conservative Scheme using Characteristic Limiting Method and MUSCL-Hancock Method with Total-Variation-Diminishing 'principle' (slope limiter). I thought about how to implement it, should I do it? (It will take another week or two)
