technological test
3.The paper studies the chemical and mineralogical compositions, the technological and physical properties of tripoli by means of chemical analysis. X - ray diffraction and technological test.
4.The chemical analysis, mechanical test, metallographic examination and technological test proved that the invention electrode can meet requirement of the standard of GB5118-85 E5515 type (similar to AWS E8015 type or JIS D5815 type).
5.Through a technological test on pure cotton down-proof fabric and pure co-tton poplin woven on 1511 looms, the paper gives out quantitatively some weaving parameters for high density fabrics, which is quite advisable.
7.Study on Mutagenic Activity of Organic Extracts from Drinking Water of Beijing in Technological Process by Ames Test
8.The components of green phosphatizing without heavy metal and nitrite at room temperature and its corresponding technological parameters were defined by orthogonal test and comprehensive assessment, and the appearance, film wight and corrosion resistance of phosphating film were examined and analyzed.
9.The author provided the basis and standard on the classification of earth and stone material from cutting according to the rock properties we also discuss the technological process quality control point and quality test for filling the roadbed with these materials.
10.An alkaline protease Alcalase AF 2.4 L was used to hydrolyze corn gluten meal and study the effects of pH and enzyme concentration on protein conversion. The optimum technological conditions were obtained in this test as follow: hydrolyzing temperature 55℃,addition of 2 ml alkaline protease(90 947 U/ml),pH=9,concentration of substrate 0.1g/ml,hydrolysis time 1 h.
