Improvement on the theory of step function is made by the adoption of new ideas of leap function and impulse function proposed. Two important theorems by which any time function can be resolved into a series of leap functions or impulse functions are derived. Certain problems, especially those in the derivation of convolution integral when calculating the response to an arbitrary input, can then be solved easily. Examples are given.

This metric describes the field of an arbitrarily accelerating charged point mass. It is a further generalization of the Vaidya star metric. This metric should have extensive meaning and may be useful for some kind of concrete models of celestial bodies

An investigation of siliceous oxide and sulfide mixed ore by reducing with hydrgen in the presence of calcium oxide have been carried out to determine the effect of temperature, mesh size, hydogen partial pressure and flow rate, The oxide and sufide (in the presence of cao) react with H_2gas producing H_2O vapor according to the following reactions: MeyO+H_2=yMe+H_2O MexS+H_2+CaO=xMe+CaS+H_2O and in the definitceondition the tatal weight of H_2O vapor droduced from above rcactiions is taken as a base for measuring the efficiency of the reduction, and thecfficency can be calculated by the following formula: α= w/w。 where, w-the weight of H_2O vapor produced from the reduction process at any time(g); W_o-the weight of H_2O vapor produced from above reduction reaction atan infinite time (g)。 The results show that with the increase of temperature, hydrogen partial pressure and flow rate; the reduction rate will be accelerated, The optimistic condition under which the reduction proceeded completely is that thetemperature is equal to 700~800℃, size of ore, -60+80mesh, P_(H_2)°, 1 atm, ±low-rate of H_2 200cc/min and the reaction time, 3 hr. The rate determing step in the reduction process is either controlled by inteface chemical reaction or by internal diffusion At the initial period (0<α<0.85) the rate law of reduction processis d[1-(1-α)~(1/3) dt=k'/RT and then, when α>0.85, the rate law changes to d 1-(1-α)~(1/3)]~2/dt=k′/RT in which the k' is apparent specific rate constant, R thegas constant, and T the absolute temperature, when the reduction process is chemically controlled, the temperature-depence of the apparent specificratc constant is given by k'=433exp[-10050/RT](500~800℃) The activation energy for the reduction was found to be 10050cal·mol~(-1) (42000J. mol~(-1)) According to the data measured, the rate of the reduction reaction is first order reaction with respect to hydrogen partial pressure as shown in the following: d[-1 (1-α)~(1/3)]/dt=k"P_(H_2)°or d[1-(1-α)~(1/3)]/dt=k′″(P_(H_2)°-P_(H_2)°)

本文研究了温度、粒度、H_2分压和H_2量对高硅含硫氧化铜矿用H_2+CaO还原动力学的影响。反应的进程用反应产生的水量进行描述(反应水经冷凝后用滴定管滴测量),金属总的还原率∝(由任意时间产生的水量与反应完全进行时产生的水量之比推算。结果表明,在一定范围内提高温度、增大氢分压和氢流量可以加快还原速度,粒度则以适中为宜,由因得到了过程的最佳条件:温度800℃,粒度-60+80目,氢分压1 atm,氢流量200cc/min时间3 hr。在此条件下,反应的动力学由界面化学反应和气体的内扩散分别控制,反应初期(0<∝<0.85)为界面化学反应控制,其动力学方程为: d[1-(1-∝)~(1/3]/dt=k′/RT 反应后期(∝>0.85)为气体的内扩散控制,其动力学方程为: d[1-(1∝)~(1/3]~2/dt=k′RT 其中k′为表观速率常数,在界面化学反应控制的条件下,k′与温度的关系为: k′=433exp[-(10050/RT)](500~800℃) 其中表观活化能E=10,050Cal/mol。此外还证明了反应速度对氢分压为一级反应。在最佳条件下,铜(氧化铜及硫化铜)的还原率趋近100%。
