文摘The magnesium has some excellent properties such as ligh quality, high specific strength and stiffness, high damp and reeoverd easily compared with steel, aluminium, engineering plastic. So the application and exploitation of magnesium arose extensive attention of the public.
文摘Parameters of the power source used to control PV-10 piezoelectric crystal valve are following DC output voltage： 0 - 120 V, continuously controllable, linear enlargement factor of input direct current voltage： approximate 25 times, the accuracy of DC output voltage： ±5%, manual control and automatic control.
