then aiming at the characteristics of the sci-tech type of enterprise of this institute, using the theory of human resource capital and inspiriting theory, analyzes the economic importance of human resource capital becoming property right and the composing of human resource capital, sets up the quantified model of human resource capital, and makes the quantified study on human resource capital of Chemical Industry Material Institute of Shaanxi;
1,3-propanediol is an important chemical industry material. It can be used as solving solution, resisting frost solution, protecting solution, delicacy chemical industry material and a monomer of new polyester: polytrimethylene terephthalate (PTT) and polyethylene terephthalate.
New chemical industry material including functional polymer is already considered as a currently underlying developing region in technical innovation, exploitation, and industrialization of Chinese chemical industry.
Sodium hydroxide (NaOH) is a kind of important chemical industry material and pure nickel is a kind of traditional material which can strongly forbear the corrosion of NaOH, so the evaporators are often made by pure nickel.
Calcium sulfate is an usual chemical industry material. Its usage as material of beauty face and skin care is investigated,and its principle of application,selection of raw material and preparation of products are introduced in detail.
A method using mercury film electrode for the oscillopolarographic neutralization titration of hexamethylenetetramine is described in the paper. The end-point is clearly visible. The method is rapid and simple,and the relative standard deviation is 0.19%. This method can be applied to the determination of (CH_2)_6N_4 in pharmaceuticals,Chemicals and chemical industry materials.
