The casing, cement and formation are continuous homogeneous isotropic elastic material.
The Poisson’s ratio of the material of cement is 0.3, the in-situ stress 60MPa, the casing internal pressure 20MPa and Young’s modulus of material of cement 5GPa-50GPa, the influences of Young’s modulus of material of cement on the casing and cement load is investigated.
Fig.3 Loads of casing and cement with Fig.4 Loads of casing and cement with different Young’s modulus of material of cement different Poisson's ratio material of of cement The affects of Poisson’s ratio of material of cement on the loads of casing and cement.
The bigger the load of cement, the bigger Poisson’s ratio of material of cement.

Microwave sintering promoted the density of materials by materials dielectric loss absorbing microwave[3].
Microwave is absorbed selectively by different materials at related temperature which leads to the phenomenon[15].

,,respectively stand for the raw material conversion factor of producing ,,;stands for exact quantity of the raw materials supplied by company; ,,respectively stand for the cost of environmental pollution this company; It accordant with the production quantities, equipment technique and so on., stands for the permissible cost of pollution of company.
It’s a typical process of production planning according to the preceding analysis, the model is used to solve optimization problem of production planning.Constraint (2)-(4)indicate that the sum of the production number must be less than the demand.Constraint (5) means the supply of raw materials can not exceed a given amount that was a bottleneck in iron and steel production.Constraint (6) bmeans, actually, the minimum of the values should be given in the view of more accurate point.Constraint (7) shows that the production costs of environmental protection .
