Article 17 when handling the alteration or extension of an export license that has been partially used, a releasing authority shall verify the inspection data and customs clearance data filled out by the customs in the customs inspection and release notes column on the first page of the export license, write off the used quantity in the release system, and issue a new license in light of the residual quantity
第十七條對已部分使用的出口許可證，發證機構在辦理更改或延期時，應核對出口許可證第一聯背面的海關驗放簽注欄中的驗訖數據和海關反饋的清關數據，在發證系統中核銷已使用數量，按所余數量換發新證。 -
The threshold speed and the typical characteristics of the oil whip of the system are simulated under the nonlinear model of oil film force, and the state of motion and type of the bifurcation are analyzed by floquet multiplicators which is computed by the shooting method. secondly, the the nonlinear dynamical model of the low - pressure rotor - bearing system by column bearing with reduced dimensions is presented. the numerical results show the rule of the amplitude with the eccentricity of rotor, the length - to - diameter ratio, oil viscosity and the clearance - to - radius ratio of the bearing under the definite speed
其次，對降維后的低壓轉子?軸承系統的非線性動力學方程，計算了圓柱瓦軸承支撐的轉子系統的振動穩定性在固定轉速下隨偏心距、軸承長徑比、潤滑油動力粘度和軸承間隙比的變化規律，並分析了轉子前軸承軸頸的失穩轉速與轉子偏心距、軸承長徑比、潤滑油動力粘度和軸承間隙比之間的關系，同時利用floquet理論分析其運動狀態和分岔類型。
