The seismic behavior of great size thin wall reinforced concrete pipe columns is discussed through model experimentations and finite element methods in this paper, after taking Air Cooled Condenser system structure of a main factory building of the large capacity power plant as experimentative prototype.

From the analysis on factors of impacting ball size,it is indicates that several impacting factors such as experienced formula or semi-theoretical formula have been comprehensively considered and the design for ball size has been conducted,thus the precise value gained.

Based on the ball size that was calculated to meet the requirement for lab test, a series of orthogonal tests were carried out to select parameters appropriate to the ball milling process.

Laser vision-based measurement of large-size part straightness;

Using this apparatus shear strength of large-size fissured loess samples formed in different time are tested with different loading methods.

Adenosine triphosphate (ATP) is an important high-energy compound widely used in clinical treatment,and,a novel separation method of using large-size anion-exchange supermacroporous cryogel was developed in this paper to isolate the ATP directly from crude fermentation broth of Saccharomyces cerevisiae.
