bagblack boardsit downused tothat timered carbookkeeper handbag blackboard sit down used to that time a red car“爆破音+爆破音”：失去爆破 6个爆破音中的任意2个相临时，前一个爆破音受失 去爆破，即由相关的发音器官做好这个发音的姿势，稍 做停顿后即发后面的爆破音。实际上只有后一个爆破音发音。For example:bookkeeper/bukki:pa/blackboard/blaekbazd/sit down/sitdaun/that time/daettaim/handbag/haendbaeg/September/saptemba/used to/ju:sdtu/a red car/aredka:/Loss of

i(t)down in the bi(g)garden.io.I bought a chea(p)book,but its a goo(d)book.不完全爆破:当一个爆破音后面紧跟着一个摩擦音、破擦音、鼻辅音或舌边音时，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。1.爆破音+摩擦音/破擦音:不完全爆破（摩擦音 10个：/f,v,a,6,s,zj,3,r,h/）（破擦音6个：/ts,tr,dr,t d3/）例如/t tf,td3,d tj,dd3,p 也 pd3,g tf,gd3/等。这样的 组合出现时，前面的爆破音就要不完全爆破。例如：picture/pik.tf e/big jug/bigdjAr/good
