2.The optimum conditions for the purifing technology with clarifying agent are as follows : B component is added first and then the A component is added subsequently, the amount of B is 1.2g/L, the amount of A is 0.6g/L,the reacting temperature is 40 ℃ , the reacting time is 40min, and the exacting solution is diluted adequately.
3.Application: Lead Stearate is the thermal stabilizer and lubricant for PVC with excellent thermal and light stability.
5.Viscosified acid has been shown to provide wider crack width and improved acid retardation over that from thin fluid when used in carbonate acidizing.
6.The results show that the 10 layers of TiO 2 film prepared by solutions(100ml)contai- ning 1.0g ployethylene glycol with molecular weight 2000, using a slow raising speed (2℃/min) to 550℃ from 100℃ and then treating at that temperature for 1h are of good photocatalytic activity for decomposition of aqueous acetic acid.
7.This paper mainly describes the selection of multi access and analyzes throughput and delay of MF TDMA with Queueing theory and simulation And then it gives the comparable re sults with TDMA By the analysis,MF TDMA′s performence is better than TDMA′s for the meshed VSAT network with large users and bursty traffic
8.Using diethanolamine as aminating agent and glacial acetic acid as neutralizing agent,aminated epoxy acrylic cationic resin was prepared.The effect of technology of aminated epoxy acrylic resin on properties of eletrodeposition was studied by conductivity meter and electrophoresis apparatus.It was shown that,conductivity firstly decreased,and then increased with aminating temperature increase.In contrast with putting polyacrylic resin into thin acetic acid solution,the more compact film could be achieved by neutralizing polyacylic resin with glacial acetic acid and then add it into water.When neutralizing temperature was enhanced,the speed of electrodepsidon was found to increase,and the film was also more compact.Increasing the DN leads to enhanced conductivity and smaller particle size.When DN equaled to 80％,the smoothest film could be achieved.
9.A small size installation using D D sealed tube neutron generator to take out thermal neutron is introduced. The optimum model to draw out thermal neutron from polyethylene moderator is determined by experimental method, and the good thermal neutron source to practical application of thermal neutron is provided.
10.C: Very well. You know, we have definite ways of packing garments. As to blouses, we use a polythene wrapper for each article, all ready for window display.
