I.e.:Syringe is filled the area for gravity/syringe bottom that pressure=liquid that liquid is placed downward vertically to bottom generates P=ρgh(PLiquid=F/S=G/S=mg/s=ρLiquidhg);

Syringe ports are closed if it is air rubber stopper is sucked in syringe, then do not apply additional pressure or the feelings of draft Atmospheric pressure is equal inside and outside syringe under condition, but once presses the pressure or take out piston rod outward that syringe inside pushes, this Volume, the temperature factor that pressure in the external closed confined space of syringe is occupied with air are related, and formula prompts for:PV= Nrt, P indicate gas pressure intensity, V indicate volume of gas, n indicate molecular weight, R are constant contained by gas, T be gas temperature, when When temperature remains unchanged, the smaller pressure of gas volume of certain mass is bigger, and the bigger pressure of volume is smaller.Density at zero altitude For:ρ=1.225kg/m3

Thrust:P=PIt pushes away+Pgh

PV=nRT

At this point, size constants are constant.T temperature changes are little,(Practical lake and reservoir environment water temperature variation is little, can be ignored), so PV= N indicates molecular weight gas in nRT:PIt is empty=1.225Kg/m3*Xnm3* the mole coefficient of y air, Pv be variable i.e.:Volume is one In the case of fixed, being applied to pushing or pulling on syringe piston push rod, power is bigger, the pressure suffered by push rod and syringe volume space Qiang Yue great, it is reversed for once clogging injection orifice with rubber stopper forms confined space, in the case where temperature is certain, syringe with Injection ram forms a stable pneumatic structure system, and the power of the structure of the suffered bigger maintenance baric systerm of external force is more Greatly.
