inner salt
3.Though the neutral salt mist experiment,the humidity and high temperature experiment for several hard coat antirust oil,such as Tecyt1506EH,DFR-F46,FX-3,the appropriate material of sea transportation rust prevention for the heavy finishing workpiece with the effective antirust coating and the design of inner packing.
4.Ac cording to the increasing of TDS, Ca2+ and 40Ar/36Ar values of ground brine and the decreasing of δD values from the outer zone to the inner zone with deepening of the aquifer in large - scale artesian basin, it can be seen that the poorness in 2H and the richness in Ca2+ may be the characteristics of the hydrosphere at the beginning and proton had beed lessened gradually from the hydrosphere during the planet - earth history, and the ground brine, salt and hydrocarbon mines derive themselves from the upper mantle initially.
5.The chemical components of silkworm pupa crust were analyzed,and its microstructure was characterized by using scanning electron microscope.The existing realtion of among chitin、protein and inorganic salt in silkworm pupa crust has been observed.The results show that the major protion of silkworm pupa chitin is in pupa crust,and it accounts for about one forth of crust weight,the out surface of pupa crust is regular polygon net vein characteristics.Chitin takes honeycomb shape in chitin-protein complex and conjugated with protein.The inner space of chitin-protein complex net was filled with inorganic salts.Thus the theory basis was provided for working out the process route of isolation pupa chitin.
