The London and South Western Railway L11 class was a class of 4-4-0 steam locomotives designed for mixed traffic work. They were introduced in 1903 and were nicknamed "Large Hoppers". As with most other Drummond productions, the locomotive had two inside cylinders and Stephenson link valve gear.

Following his K10 class of 1897, Dugald Drummond produced another 4-4-0 using the same firebox though with a coupled wheelbase 1' longer at 10' 0", the L11 class, in 1903. Whilst the K10s were known as "Small Hoppers", the L11s were the "Large Hoppers".

本研究搜集了有机污染物的线性溶解能关系 (LSER)参数及Kd值,构建了可预测有机污染物在聚丙烯微塑料与海水、聚乙烯微塑料与海水、聚乙烯微塑料与淡水之间Kd值的LSER模型。 模型具有良好的拟合优度 (R2adj介于0.794~0.903)、稳健性 (Q2LOO和Q2BOOT分别介于0.763~0.863和0.720~0.804)和预测能力 (R2ext和Q2ext分别介于0.886~0.971和0.825~0.954),能够用于预测多氯联苯、多环芳烃、六氯环已烷和氯苯类有机污染物的Kd值。

结合修改的Soczewiñski模型和一个梯度运行，开发了一种梯度方法来建立正相色谱的线性溶剂化能量关系（LSER）。 梯度法在二硝基苯胺丙基（DNAP）和硅胶色谱柱上以己烷/二氯甲烷（DCM）流动相进行测试。

答:线性溶解能关系即Linear Solvation Energy Relationships, 简写为LSER。 Kamlet 等人的研究表明,溶解包括三个与自由能有关的过程: (1)在溶剂中形成一个可以容纳溶质分子的空穴;
