The influences of wave Numbers, Angle of incidence, combination of different media parameters and cavity shape upon the DSCF around the cavity are discussed.

讨论了入射波数、入射角、不同介质组合以及孔的形状对孔附近动应力集中系数的影响。

The wave shape of Voltage in 3-phase controlled rectification is not as same as it does in circuit. The wave shape of common-cathode circuit is also different with that of common-anode.

晶闸管三相半波可控整流与逆变电路的电压波形是不同的，而共阴极接法与共阳极接法的波形又有所不同。
