1、失去爆破和不完全爆破,爆破音+爆破音（爆破音：/p,b,t,d,k,g/）当一个爆破音后面紧跟着另一个爆破音时，前面的爆破音不发生爆破。方法是：对于前一个爆破音，只作发音的姿势，刚要发出时，立即发出第二个爆破音。这种现象叫做失去爆破。例如/p,b,t,d,k,g/这样的组合出现时，前面的爆破音就需要失去爆破了。例如：what time/wt taim/goodbye/,gudbai/bedtime/bedtaim/big kite/big kait/,2爆破音+摩擦音或破擦音（摩擦音：/f,v,s,z,r,h/）（破擦音：/ts,dz,tr,dr,t,d/）当一个爆破音后面紧跟着一个摩擦音或破

2、擦音时，前面的爆破音只作部分爆破。方法是：对于前一个爆破音，作好发音的姿势，刚发出时，立即过渡到第二个摩擦音或破擦音上去。第一个爆破音发出的声音是非常轻微的，有时甚至听不出来。这种现象叫做不完全爆破。例如/t t,td,d t,dd,p t,pd,g t,gd/等。这样的组合出现时，前面的爆破音就需要不完全爆破了。例如：picture/pik t/big jug/big d/good child/gud taild/that joke/t duk/,3爆破音+鼻辅音或舌边音（鼻辅音：/m,n,/）（舌边音：/l,=/）当一个爆破音后面紧跟着一个鼻辅音或舌边音时，前面的爆破音也产生不完全爆破现象
