Hello everyone,
大家嚎， 

Wargaming (on RU portal) made a post, explaining what’s going on in the new 9.3 ricochet mechanics.
WG（在毛服的官网上）发了个贴，里面解释了9.3的新跳弹机制是怎么样的。 

How it works now
现在（指9.2）是怎么样的 

A ricochet is a deflected shot, that hits the armor under a very steep angle. In World of Tanks case, if the AP or APCR (subcaliber) shell hits the armor under the angle of 70 degrees or greater, the shell will automatically ricochet – it will be deflected by the armor without doing any damage. For HEAT shells, the angle is 80 degrees. HE and HESH shells on the other hand do not ricochet at all. Ricochet check is performed when the shell hits the armor (normalization is performed after ricochet check).
跳弹，顾名思义就是在入射角过大的时候被装甲弹开的炮弹。在WOT中，如果AP或者APCR（次口径弹）的炮弹在击中装甲时的入射角大于70°的话，炮弹会被自动跳弹—在不造成任何伤害的情况下直接被弹飞。对于HEAT弹而言则是80°。HE和HESH弹则根本不会跳弹。跳弹检测是在炮弹击中装甲的时候进行的（转正计算则在此之后）

Ricochet however does never happen when the “three calibers rule” is applied. This rule says that when the gun caliber (gun, not shell) is three times higher than the armor thickness, ricochets do not happen (HEAT shells do not use this rule however). Furthermore, ricochets do not happen when external modules of the tank are hit (tracks, optics and gun).
然而跳弹会被“三倍口径”规则所压制。这条规则说的是主炮的口径（是主炮的，并不是弹药）大于装甲厚度的三倍时则必定不会发生跳弹（HEAT弹不适用此规则，详见这里） 。还有就是在炮弹击中了坦克的外置模块的时候（履带，观察镜以及炮管）的时候是不会跳弹的。

What is changed
改了什么 

Currently, two types of ricochets can happen. A shell can ricochet into a the tank (for example in a shot trap) – if, after it ricochets, the shell trajectory aims again at the tank, the shell tries to achieve penetration yet again. If it fails, it disappears. If the shell ricochets off the tank altogether in first place, it disappears.
现在的话会出现两种跳弹。一枚炮弹可以跳弹进一辆坦克（栗如窝弹区）—如果在跳弹之后，炮弹的弹道瞄准的依然还是这俩坦克的话，炮弹会试图再次进行击穿。如果失败的话，炮弹就会消失。如果炮弹在第一次跳弹之后就从坦克上面飞走的话，那它就没了。 

In 9.3, after the first ricochet happens, the shell will continue on new trajectory in any case (it does not disappear regardless of where it flies). When that happens, APCR and AP shells lose 25 percent from their base penetration value, HEAT shells keep the same penetration value. If the ricocheted shells (with reduced penetration) hits another vehicle, the hit will be calculated based on normal game mechanics. Second such ricochet is not possible (if the shell ricochets again, it disappears).
在9.3之后，在第一次跳弹之后，炮弹在任何情况下都会沿着新的弹道继续飞行（而不会像以前一样消失）。当这种情况出现时，APCR以及AP炮弹的穿深值会下降基础穿深的25%，HEAT弹则会保留穿深。被弹开的炮弹（穿深衰减之后）击中了另一辆车的话，会按照正常的游戏机制来进行击穿判定。炮弹无法再进行第二次这样的飞行（如果炮弹被第二次弹开的话，它就会消失） 

Ricochets of your shells, hitting an enemy and ricocheting off, damaging your teammate, will not be punished.
你的炮弹在打到敌人身上之后被弹开，随后击中了你的队友这种情况是不会受到惩罚的。
