Introduction Brand attitude accessibility is related to brand attitude strength, which is usually viewed as a well-established feature of attitude strength.

The re sults showed that the explicit attitude tended to be consistent with implicit at titude when attitude strength was strong, but the two scores tended to be oppose d when attitude was low.

Then the basic science problem connected with materials ballistic performance closely such as dynamic strength,absorbed energy rate,adiabatic shear deformation localization and dynamic hardness are discussed primarily.

Taking the component sectional sizes,the material strength and the material density as the random variables,and based on the movement analysis and the dynamic analysis while taking the Assur-Group as the unit,a general method of mechanism dynamic strength reliability analysis was established.

In this study,the effects of hot briquetting process parameters on cold strength of the CCB,and the mechanism of the CCB high strength are investigated and discussed.

The effects of coal from different mines and hot briquetting process parameters on the cold strength of CCB were investigated,as well as the mechanism of acquiring high strength of CCB.

The coke yield,cold and hot strength were inspected.

It is suggested that to more efficiently improve the cold strength and hot strength of the coke,the coking time should be properly prolonged if production conditions are permitted.
