大家看看这段话有哪些错误，谢谢！
The mechanical parameters of cement not only affect mechanical analysis of engineering structure under downhole working condition , but also linked to cement sheath using security judgment.through measuring mechanical parameters of oil well cement using mechanical parameters tester(MPRO) under different curing temperature (45 ℃ - 150 ℃), pressure (0-40MPa), the oil well cement contain class G oil well cement,jiahua gigh-strength low density cement and so on,this paper discussing curing time, curing temperature, pressure and admixture (outside admixtures) influence on elastic modulus,poisson's ratio and intensity of cement paste. |
