Construction and operation of a laboratory model, which combines the lately discovered enantioenrichment method of the author (2007) with the sun-powered evaporative pumping process of Hsu and Siegenthaler (Sedimentology 12:11-25 1969), is described. The model operated continuously for 120 days before it was intentionally shut down, even though it could have continued. During that time it raised the enantiomeric excess of the test material by a factor of 3.6. Implications of these results on the origin of biohomochirality are discussed.
描述了一种实验室模型的构建和运行，该模型结合了作者（2007 年）最近发现的对映体富集方法和 Hsu 和 Siegenthaler 的太阳能蒸发泵过程（沉积学 12:11-25, 1969）。该模型连续运行了 120 天，然后被故意关闭，尽管它还可以继续运行。在此期间，它将测试物质的对映体过量值提高了 3.6 倍。讨论了这些结果对生物同手性起源的影响。
