The principles and methods of static measurement of the dynamic displacement, the corresponding relation between the lateral acceleration and the equivalent cant, the calculation of carbody swing displacement and the actually measured curve are described in this paper.

Under the condition of general shear failure of soil, this paper offers the expression of Nr , discusses the formulas when soil cohesion C transformed into equivalent overload and makes comments on ultimate bearing pressure of Taylor and Vesic respectivel.

The equivalent depth and a brief and useful method of deflection calculation is derived from the analysis of the calculation results.

According to the important position of motor in energy-saving and emission reduction, this paper has introduced the developing condition and standard of abroad asynchronous motors with high-efficiency and super high-efficiency, and the current condition and problems of domestic motors.

Energy consumption of super-high-rate anaerobic bioreactor
