However, the applicability of batch tests has been discussed and criticized as the advancement of technology has relaxed the aforementioned limitations.It was recognized that the distribution coefficients (Kd) of batch techniques are too simple to represent the reaction system of interest in many cases. However, it was found that the diffusion techniques that are frequently used, gives more accurate information about the radionuclides in deep geology.5,6 Some literatures7–9 have discussed the advantages and disadvantages of Kd and Rf obtained by the two methods. Generally, all experimental results showed that the Kd values derived from the diffusion tests are more accurate to evaluate the transport of radionuclides in compacted media than those obtained from batch experiments. However, most Kd values are acquired by the batch method because of its simplicity and convenience in the experiment. |

| 然而批量測(cè)試的應(yīng)用性受到討論和批評(píng)，因?yàn)榧夹g(shù)的發(fā)展放松了前述的限制。現(xiàn)已發(fā)現(xiàn)批量技術(shù)的分配系數(shù)（Kd）過(guò)于簡(jiǎn)單，在很多情況下不能代表所關(guān)注的反應(yīng)體系。然而，得到頻繁使用的擴(kuò)散技術(shù)對(duì)深層地質(zhì)的放射性核素給出更準(zhǔn)確的信息。5,6 一些文獻(xiàn)7-9討論了2種方法得到的Kd和Rf的優(yōu)勢(shì)和劣勢(shì)�？傮w上，所有實(shí)驗(yàn)結(jié)果顯示，對(duì)于評(píng)價(jià)放射性核素在壓縮媒介中的運(yùn)輸，擴(kuò)散試驗(yàn)得到Kd值比批量實(shí)驗(yàn)更準(zhǔn)確。然而，由于實(shí)驗(yàn)簡(jiǎn)化便捷，Kd值更多地通過(guò)批量方法獲得。 |
