It was found that the critical initiation particle velocities for almost all of these explosives are relatively constant for densities less than about 0.95 theoretical maximum density. The only exception was found to be nitroguanadine. The experimental critical particle velocities were produced with ...

1.The smallest angle of incidence at which a light ray passing from one medium to another less refractive medium can be totally reflected from the boundary between the two. 2.The angle of attack of an airfoil at which airflow abruptly changes, causing changes in the lift and drag of an ...
The effect of nano-Al_2O_3 on critical initiation pressure of HMX/nano- Al_2O_3 is studied using copper-manganese piezo-gauge testing pressure and small scale gap test (SSGT), and the effect of nanometer Al_2O_3 on composite explosive mechanics of explosion are discussed, density of HM...

the decreasing particle size of HNS,the critical thickness decreases,and the propagation capability of detonation waves increases.Increase of charge density is advantageous to detonation waves propagation.When the charge density of HNS-Ⅳ(89 nm) is 1.570 g·cm-3,it's critical thickness is 0.46 mm...

Critical population density has also not been previously linked to unstable equilibria that yield shifts in predator-prey balance as found here. Familiar natural examples of unstable equilibria, where small local changes lead to large and sudden transfers of energy and state, include avalanches, earthq...
