composition of forces
2.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.
3.This thesis proposes a kind of soft firing technology , which combines interior ballistics with atmospheric pressure transmission theory , utilizing the energy of advancing primer ignition of piston promoting pill to counteract the counterforce of firing pill , utilizing unilateral valve on the piston to adjust automatically the gas pressures of two connected chamber in series in front and at the back of the piston, thus achieving the goal of reducing composition of forces of gun bore and increasing initial velocity of pill.
4.The "Mass Transit Vehicles Movement Simulation" is chiefly depends onAv the theory of △s=s_2-s_1=△v/(ξ·c_D)V_p thereinto, As is the distance change incourse of velocity change △v, v_p is the average velocity to △v, c_p is the unit composition of forces to v_p.
5.We have decided that in the struggle to obtain the return of security money and especially in punishing law-breaking landlords, one aim is to further weaken the feudal forces, and the other is to make sure the poor peasants and farm labourers receive appropriate economic benefit so as to mobilize them and transform the composition of the leadership of peasant associations.
