The experimental conditions of antimoyphosphorusmolybdenum ternary complexes photometry for determination of high phosphorus content in 016～04 mol/L nitric acid media are studied.

The plating conditions show great influences on the P content of the coatings and thus the corrosion resistance.

For example,the P content of the degumming oil is difficult to reach 200 mg/kg by pure water degumming,and even if the P content in the oil is less than 200 mg/kg,the specification of the oil can′t reach the 280℃ heating test.

The factors affecting the quality of phosphorized copper anode used for acidic copper electroplating were discussed, including materials, grain structure, phosphorous content and cleaning of anode surface.

The results are as follows: water stress does not reduce phosphorus content of aerobic rice root,on the contrary,that of the severe water stress increased at vegetative stage and reproductive stage.

Significant correlation was found between the increment and phosphorus content of the leaves of Eucalyptus urophilla, Pinus elliottii and Cunninghamia lanceolata .

Based on the data from field experiments,the phosphorus content and phosphorus accumulation of rice plants were analyzed,and phosphorus distributions in different parts of rice were studied as well.

The chemical Ni P plating mechanism in acid baths and the major aspects which influence the plating rate and P content of Ni P alloy coatings were discussed.

According to the 100-grain weight,15 P-tolerance and 5 low-P sensitive typical inbred lines were selected to investigate P content,starch,oil,and protein in grain as indexes,and the correlation among the indexes under two treatment levels of P as 120 kg P_2O_5/hm2(PI)and 0 kg P_2O_5/hm2(PO).
