charge weight
1.Through adjusting the parameters such as piston quality、the diameter of unilateral valve、 charge weight、charge form coefficient and the delay time of lighting fire etc to make the soft firing system reach the best state of dropping the composition of forces of gun bore and increasing initial velocity of pill.
7.Specific measure is social insurance device unite to enterprise and worker according to fixed computational cardinal number and extraction scale collect emeritus fee, form the emeritus fund that consolidates management by social insurance device, extend according to the real need of emeritus charge again retired worker, in order to change emeritus charge complete by the practice of this company load, solve company load thereby the problem of emeritus charge attach too much weight to this and too little weight to that, the equal competition that is an enterprise creates a condition.
9.The reactivity of the derivates of BTA and isoquinoline in the neutral or acidic solution were analyzed through the charge distribution , contribution to frontier orbital and Fukui indices of weight atoms by means of density functional theory(DFT) calculations, at the level of B3LYP with the 6-31G* base sets;
10.The optimum conditions of pulping were as follows; charge of effective alkali 14% (based on Na2O), sulfidity 30%, ratio of weight of oven dry wood material to volume of cooking liquor 1:5, and H-factor 1000. With the elemental-chlorine-containing sequences, ECF (elemental chlorine free) sequences and TCF (total chlorine free) sequences, bleached kraft pulps with high ISO brightness and high physical properties could be produced.
