B) Design principles. Many people have listed seven principles, such as single duty principle, opening and closing principle, Richter substitution principle, dependence inversion principle, interface isolation principle, composite reuse principle and Dimit principle. LSP, I elevated it to one of the three cornerstones of the object-oriented paradigm; Single responsibility and interface isolation are mainly used as the principle of responsibility division in object-oriented analysis/OOA, which you can not pay much attention to at this time. Relying on the inversion principle, I throw it away as garbage, because the opening and closing principle or directly "relying on abstract type principle" already contains the essence of relying on the inversion principle, while the dross of relying on the inversion principle is inherited by IoC. Of course, the pullback, I emphasize very much. Therefore, you need to master the abstract dependency principle (OCP), one-way dependency principle (including the learning of callbacks) and the minimum dependency principle (composite reuse principle, Dimit rule).

At that tail of the warhead, the drag armour-piercing firebomb is filled with a drag agent and a fireagent, Under the pressure of propellant propelling warhead, it will spontaneously ignite to produce open flame, So it can break through the oil drum and ignite or detonate the gasoline. However, the old-fashioned traced armour-piercing firebombs have obvious trajectories due to traced light when they are launched. Therefore, it is very easy to expose oneself while pointing targets to friendly forces. Therefore, the new tracer armour-piercing firebombs now equipped all start to burn and emit light only after the projectile flies out of the muzzle for a certain distance (the generally set safe distance is 100 meters, which makes it impossible for the enemy to judge the firing position with tracer ammunition, while targets within 100 meters do not need to be indicated by tracer), The principle is generally to ignite the tracer and combustion agent carried by the projectile by accumulating the heat generated by the warhead's friction with the air after flying for a certain distance to a certain extent.
