A large difference is found between the obtained metastable phase diagram at 35 ℃ and Vant Hoffs stable phase diagram at 25 ℃. The crystallization regions of schoenite(K2SO4*MgSO4*6H2O), epsomite(MgSO4*7H2O), magnesium sulfate pentahydrite(MgSO4*5H2O) and starkeyite(MgSO4*4H2O) disappear and the crystallization regions of leonit and astrankit are greatly incresed.

所得35 ℃介稳相图与Vant Hoff 25 ℃稳定相图比较有较大区别：软钾镁矾（K2SO4*MgSO4*6H2O）、七水硫酸镁、五水硫酸镁及四水硫酸镁结晶区域消失，钾镁矾和钾盐镁矾结晶区域显著扩大。

In order to comprehensively develop and utilize C. cathayensis exocarp and provide reference for protection of ecological environment at growing districts of C. cathayensis, inorganic constituents in C. cathayensis exocarp were analyzed by atomic absorption spectrometry. The results showed that content of K element in C. cathayensis exocarp was high, and the results of wet digestive and dry digestive methods were same.

为了综合开发利用山核桃外果皮，为山核桃产区生态环境的保护提供参考，经原子吸收分光光度法分析得知：山核桃外果皮的无机成分中含有较高的钾元素，山核桃外果皮可以作为制备工业钾盐的原料，湿消化法和干消化法处理外果皮所得的结果基本一致。

This paper presents the experimental data of metastable phase equilibrium of Na+, K+, Mg2+∥Cl-, SO2-4-H2O quinary system at 35 ℃, from which the metastable phase diagram is drawn. It consists of nine regions of crystallization saturated with sodium chloride, potassium chloride, glasserite(3K2SO4*Na2SO4), leonite(K2SO4*MgSO4*4H2O), kainite(KCl*MgSO4*2.75H2O), thenardite(Na2SO4), astrankit(MgSO4*Na2SO4*4H2O), carnallite(KCl* MgCl2*6H2O), magnesium sulfate hexahydrite(MgSO4*6H2O) and bischofit(MgCl2*6H2O).
