在国际放射防护委员会(ICRP)1990年新建议书中,引入了一个新的权重因数——辐射权重因数W_R,以取代原来使用的品质因数Q,用于对组织或器官中的平均吸收剂量按辐射品质进行加权。
In ICRP 1990 Recommendations, a new weighting factor——radiation weighting factorW_R was introduced to replace the quality factor Q for modifying the absorbed dose averaged over atissue or organ.
生命是以沿着球形辐射的轨道所存在的,而你的轨道正是由你的意图和你聚焦的品质所决定。
Life exists in orbs of flowing spherical radiance and your orb is defined by your intentions and the quality of your focus.
其中,辐射及对流传递主要集中在玻璃上,传导传递主要在窗框及玻璃,而空气渗漏则大部分是由门窗结构不合理或密封材料品质不佳造成的。
The radiation mainly happens on the glass surface, and the transmission on the window frames and glass. The air leakage is mostly owing to the improper window structure or bad sealing.
