This paper applied relational analysis to the process of enzyme production from white-rot fungi, and calculated the incidence degree for the four factors influencing enzyme production.

Replacing jigger and improving cleaned coal quality and yield;

Measures for enhancing yield of 5-aminolevulinic acid produced by R.sphaeroides;

Study on the Yield of Peroxides from Atmospheric Reaction of CH_3C(O)CH═CH_2 with O_3 by Long Path FTIR;

Using the infinite-mini-heat sources furnace, the effects of the raw materials、gradation of raw materials、electric power and time on productive rate of β-SiC ultrafine powder were studied, the grain size and XRD of β-SiC ultrafine powder is analyzed too.

It also studied the influence of dehydration temperature, dehydration time, cracking temperature and different kinds of catalyzers on productive rate of lactide, and established the optimum reaction conditions by the orthogonal experiment: 120 ℃ for dehydration temperature, 4 hours for dehydration time, 240 ℃ for cracking temperature, stannous caprylate for catalyzer.

Thus the productive rate has come up to 60 percent.

Study on the factors affecting the productivity of porous silica powder prepared from wollastonite;

The influence of current density on yield,productivity and degree of graphitization of .

The influence of third monomer and initiator content on productivity and dye uptake of PAN were investigated.

This is a new conceptual design for half micro-scale experiment of the preparation of bromoethane,because of when changing the quantity and adding the way of the feed stock,no any infection to the rate of production of bromoethane.

The results showed that the rate of production would reach 85%,the purity of product is over 95% when the conditions are as follows: temperature is between 50~70℃,normal pressures,reacting time is about 3 hours.
