W must consider the accelerator work load factor W, orientation ( use) factor U and the occupancy factor T of related persons so as to shield the photons produced in wide-angle bremsstrahlung, In the design of the LINAC laboratory of Nanjing University. 对宽角度轫致辐射光子的屏蔽,应考虑加速器工作负荷因子w,x射线束定向因子U,和有关人员居留因子T。对散射光子的屏蔽,根据Braestrup和Wyckoff的近似方法进行设计。
The parallel transient flow computations for a large diversion project have an accelerator factor of 1.442 with two computers with the results the same as using a serial computation. 当使用两台计算机并行计算时,计算的加速比达到1.442,且并行和串行计算结果相同。
Generally, if one wants to calculate the accelerator monitor units he needs to search the table when ascertaining percent depth dose, tissue-maximum ratio ( TMR), wedge factor and field size output factor in conventional external irradiation. 常规外照射治疗时,通常要由查表的方法来确定百分深度剂量PDD、组织最大剂量比TMR、楔形因子以及射野输出因子,从而计算出加速器跳数(MU)。
