It has the same transmissionconstant as the exciting mode, but its amplitude reduces at the decreasing ratio of core radium.
它具有与激励模相同的传输常数，但幅度却以芯径渐缩的速率衰减。
2
With its constant revision and perfection, its transmission rate is higher and higher.
随着其不断的修订与完善其传输速率也越来越高。
3
With the constant perfection in theory, design and manufacturing technologies of vehicle automatic transmission, its application scopes become wider and wider.
