The accident occurred at about 10 . 30 pm . a private car travelling along route twisk towards tsuen wan reportedly lost control and collided with another private car travelling on the opposite direction 昨晚约十时三十分，据报一辆私家车沿荃锦公路往荃湾方向行驶时，与另一辆向相反方向行驶的私家车迎头相撞。
As crystallization progresses across the temperature gradient , it is possible to move the sample by precise stepper motor control ( at specified rate ) in the opposite direction so that the crystallization front remains in the field of view 当沿着温度梯度方向发生结晶过程的时候，可以向相反方向通过高精度步进马达移动样品，这样可以把结晶前沿始终保持在视域中。
Referring to the existed methods and abundant experiments , a new engineering - oriented technique named single - point phase - detecting vibration - resistant method is presented . it uses piezoelectric transition ( pzt ) as its device for phase compensation to guarantee measure precision 当振动引起干涉条纹变化时,控制压电陶瓷( pzt )移相器向相反方向移相来锁定干涉条纹相位不变,稳定干涉图保证测量精度。
