Based on the experiments,this article emphasizes the influence from aluminum and magnesium content to the etching performance of microcrystalline zinc board.

The uncertainty of Al content were 0.

The Zn-Al alloy coat mass of steel wire with different diameters can be increased and Al content can be controlled as controlling N_2 Pressure and improving Dv value.

,Baosteel Group,through analyzing the plate's texture,metallurgical structure,grain orientation,hardening index,plane plastic strain ratio and cold forming performance with different aluminum contents,influence of aluminum on plate's processing properties has been discussed from the angle of the product's microstructure.

But the aluminum is an intoxicating factor with special bio-toxicity,thus,the determination of aluminum content is very important for quality of life.

Effects of aluminum content and temperature of molten aluminum on formation of second phase particles by thermal explosion synthesis of Al-Ti-C and grain refining results were investigated.

The article mainly introduces the new method of using chromazurine S as developer spectrophotometry to determine aluminium content.

The content of aluminium on 33 foods,drinks and drinking water in Nanping area were determined.
