Their safe margin functions are established from the angle of the automated machine ' s moving differential equation and the transform of energy , after the relation among the members of the machine has been attained 在分析了啟動階段各構件的運動關系以后,利用自動機的運動微分方程及能量轉(zhuǎn)換關系建立了上述階段兩種可靠性計算的安全余量方程。
Results and conclusion : the extracted esophageal boundary variations between adjacent time frame sequences can be applied to estimate the tumor motions as well as the required safe margins 結論:移動評估的結果,有利于治療計畫中安全邊距的縮小,在腫瘤治療劑量增加時仍能有效控制正常組織所接受之劑量,降低正常組織副作用發(fā)生機率及其發(fā)生的嚴重程度。
Because the value of securities , including those of the exchange fund paper on the liability side , fluctuate in response to changes in interest rates , we have a practice of keeping in the currency board account us dollar assets that exceed the monetary base by a safe margin 由于證券價值包括負債方的外匯基金票據(jù)及債券會受到利率變動的影響而有起跌,因此我們向來都是確保貨幣發(fā)行局帳目內(nèi)的美元資產(chǎn)超出貨幣基礎一個安全幅度。
