| 摘 要： | 代森锰锌不同的结构和命名问题值得研究。为此，用X-光衍射仪和扫描电子显微镜扫描，并用金相显微镜测定粉碎前后代森锰锌样品的颗粒尺寸。测得Zn／Mn比值存在统计学上的显著差异。此外在未经粉碎的代森锰锌样品表面Zn／Mn比值比粉碎后的低。代森锰锌不是锌和锰的定组成化合物。代森锰锌可能是一个处于非平衡状态的固溶体；母体是代森锰，锌离子在代森锰晶格中取代锰离子。因此作者用Mn1-xZnx（EBDTC）表示代森锰锌。

| Abstract: | Investigation is needed into the structure and naming of mancozeb. An X-ray diffractometer, scanningelectron microscope, and metalloscope were used to determine granule size of a mancozeb sample both before andafter sample grinding. Differences in Zn/Mn ratios were statistically significant and the Zn/Mn ratio on thesurface of unground mancozeb samples was lower than that of ground samples. Thus mancozeb must not be a Znand Mn compound of definite composition. Rather, mancozeb may be a solid solution in a state of non-equilib-rium with maneb as the matrix and Mn2 ions substituted by Zn2 ions in the maneb lattice. Hence, mancozeb isherein expressed as Mn1-x Znx (EBDTC). |
