According to a lot of test,contrastive and analytic method which compare a used sizing with different sizing,the test of size performance,sizing film and sizing quality about different sizing instruction,the optimized result of sizing instruction can be obtained to blended bamboo /cotton yarn,which have a little PVA of environmental pollution.

According to the test of sizing quality,it has been proved that excellent sizing instruction can meet sizing quality of towel.

The paper analyzes the influence of size formula on the cost and price of fabrics,and presents the economic analysis mdthod for size formula.

Test research on materials compounding of massive concrete under special environments;

Making a start on research on raw materials of shotcrete,aiming to local environments of high temperature and high humidity in which shotcrete located the specimens were conserved and pressed by means of simulating test that it simulated local environments of high temperature and high humidity,and ultimately the materials compounding of shotcrete was determined.
