Considering many influencing factors and the indetermination of coefficients,it's inconvenient to calculate the radiological risk of DU(depleted uranium) with PLEIADES(Program for Linear Age-dependent Dosimetry).
针对线性年龄相关剂量学程序PLEIADES(Program for Linear Age-dependent Dosimetry)计算贫铀辐射危险存在的影响因素较多、系数不确定性大、使用不便的问题,基于ICRP生物动力学模型,采用美国原子管理委员会编制的放射性物质工具箱中提供的典型条件下铀的各同位素剂量转换系数,分析了不同背景下剂量的影响因素,给出了贫铀的辐射危险概率的简化计算方法,并同PLEIADES的结果相比较。

补充资料:地价评估趋势评估法
地价评估趋势评估法
【地价评估趋势评估法】土地价格在一定的时间内由于受诸多因素影响,呈周期性的波动,但总趋势是上升的,因此,利用一定的数学模型,就可以求算出地价,一般要通过回归分析,找出土地价格与时间变量之间的函数关系,画出地价发展变化趋势图形,然后建立数学模型,进而推算出地价。若以Y代表历年地价,X代表时间,丫代表地价,其关系式为:y‘=a+bx(a、b为常数)。采用这一方法,需以长年积累起来的地价变动资料作为分析依据。地价的时间序列最好在ro年以上。因为时间序列愈长,愈能排除偶然因素和短期因素对趋势值的异常干扰。另外,用地价长期趋势图可比较两个地段地价_L涨的强弱程度,如果长期趋线越陡,则表明该地段地价升值性越强;反之,则表明该地价的升值性越弱。
