Biminimal hypersurfaces in a sphere

In this paper, we mainly concentrate on the biminimal hypersurfaces in a sphere. First, we obtain some rigidity theorems for biminimal hypersurfaces. Then we give a classification of non-minimal biminimal isoparametric hypersurfaces in a sphere.     

GC－MS法分析柑桔属果皮精油 Ⅲ．梅县沙田柚精油分析

沙田柚表皮以水蒸气蒸馏得精油，精油经硅胶柱色谱分离成二部分，再分别用ＧＣ－ＭＳ分析，经计算机对ＡＳＴＭ谱库检索，鉴定出柠烯、香叶烯、石竹烯、松油醇、香芹醇、奴卡酮等２２种组分，其中柠烯含量为９５．５％。
