Purpose To study the correlation between the right bare area of the liver (BAL) and the retroperitoneum, and the localization about organ origin of large mass in this region by CT.
The simulation is also made to describe the heat and mass distribution under the same environmental conditions between vegetation soil-bed and bare soil-bed.
同时，在相同环境条件下对有作物覆盖的土壤床和无作物覆盖的土壤床中的水热分布也进行了模拟比较。

Giving the conscientious thinking to the mass safety appearing in the project combining with concrete engineering accident case, announce to at present bare concrete mass problem.
