By analyzing the case of a weak organized collective strike of taxi drivers,this article proposes two concepts of the hard and soft compulsory mobilization and gives a new explanation to why weak organized collective actions are possible.

The effects of vibration parameters on the drying behavior in a VFB dryer are studied on a modelling set-up with after-distillation grain dregs,soy dergs,corn and wheat taken as sample materials and vibration intensity as the performance index of all vibration parameters.

The results show that the vibration intensity at foundation is decreased with the increase of the weight of superstructure and the burial depth of foundation,and that the FFT predominant frequency at foundation is slightly decreased with the increase of the weight of superstructure.

For solving the problem that mixing quality,vibration intensity and working reliability can not be ensured at the same time in the study of vibratory mixing,authors put forward a new vibratory mixing technique.

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.
