explosion chamber造句

• It is possible for further collapse to occur from the sink into the explosion chamber.
• The walls of the explosion chamber were thickened to strengthen the chamber so that it could withstand the propellant explosion.
• The two explosion chambers were excavated in the 175 Fathom Level, where it had been extended south of the Clay Vein and a long crosscut had been driven in an attempt to find an extension of the Greenside Vein.
• Since the area of effect on the launcher in the explosion chamber is small in diametre ( about 4 inches ) and the area the vortex effects is larger ( around 2 foot ) the target will be moved further backwards than the launcher, since larger area and less force are better for moving objects and even though the launcher feels more kinetic energy it is over a much small serface area . ( for example like a sail on a large ship . 100 psi focussed on 1 foot of the ship would not be as good for moving the ship as 0.3 psi focused on the 30 feet sail?
