1. This is a columniation which is for locating purpose.

2. The inner standing columniation can be adjusted from front to back as per different request, and the layer plate can be adjusted fluctuated to fix easily.

3. Some explosive is examined by X-ray when X tube current and height of explosive columniation are fixed, and penetration rates are fitted by regression analysis method.

4. Through the calculation the article studies the calculating bending strength of steel reinforced light weight concrete columniation with no reinforced bar.

5. The related theory of adsorptive isotherm was studied about columniation layer analyse in the last of thesis.
