Described are the main technical parameters,structural general,bases for calculation of tank and selection of technical parameters,static strength performance test,dynamics performance test and trial operation of the T 64 type railway transport car for special medium.
By analyzing the weldability of the thick plate pressure vessels with humid H_2S medium, welding material with low content of S and P and reasonable welding technology were used to control the hardness of the weld and reduce welding stress, which improved safe performance ability under the special medium condition.
But for some special medium materials,such as liquid crystal display controller PCB,magnifiers must be used to gather images to gain enough precision of inspection for the weak contrast between the basic board and the conductor .
The lime white is one special medium, comparing with water and oil, it is the fluid - solid suspension, which contains the bigger solid particle , at the same time , it is also serious to the spray nozzle attrition, whose density and the viscosity are big, even its atomization is more difficult, and it has corrosiveness. Therefore it must set a higher request to the lime white spray nozzle.
The article comments common electrochemistry metering methods in soil corrosion research such as: ground polarization oxidization and reduction potential, polarization resistance and curve and alternating impedance etc. analyses of these conventional electrochemistry metering methods when applied in soil, a comparatively special medium, would be subject to some restriction and compares the advantages and disadvantages of these methods.
③ Adipose-derived stem cells were isolated from the fatty tissue under the skin of abdomen of the rabbits by trypsin digestion and cultured with Iscove modified Dulbecco medium supplemented. The second-generation adipose-derived stem cells were divided into two lots. One was cultured with endothelial special medium supplemented with cytokines and the other was cultured with Iscove modified Dulbecco medium for 2-4 weeks to observe the changes of the cells.
The primary endothelial progenitor cells and passaged cells were all growth rapidly. After being cultured with endothelial special medium for 2 weeks there were insignificant change of the cell formation but similar to the endothelial cells the adipose-derived stem cells began to take up acetylated low-density lipoprotein and were positively stained for type Ⅰ ulex europaeus agglutinin and Von Willebrand factor related antigen monoclonal antibody.
Results showed that bafidobacterium adolescent could grow as well as growing in the special medium for bafidobacterium adolescent and the polysaccharides in the fermentation broth had little change when it was used as bafidobacterium adolescen media.
