The development prospects of nano weapons
Technological progress constantly, weapons development and military in the field of wave upon wave of change, the future battlefield and will be how to earth? Some assumptions, the future will outbreak of the war that can't see both sides of the combat troops on the battlefield, aircraft, tanks and artillery were whirling in the sky fly, the hornets kind of miniature unmanned aerial vehicles and hordes of ants on the ground kind of miniature robot forces that war is like magic in Lilliput war, when ordinary people unable to detect the outcome has been decided.

The Principle of hydraulic damper
Hydraulic damper is a device that to reduce the resistance of movements, and then depletes the kinetic energy. Hydraulic damper is widely used in automotive and medical equipment; the feature is the resistance changes with running speed. Obviously, it can play a buffer role in connected institutions. The most important feature is that the force of the gas spring changes with velocity of movement. Significantly, when the force point of gas spring movement faster, then the resistances of the spring is increased. In other case, when the force point m...
