Two specieses, Lycoris radiate and Lycoris aurea, were selected for the studying of artificial propagation in vitro. A few specieses of Lycoris, from the southeast area of China and part of locations in Japan, were chosen to research their karyotype differentiation and to measure their genetic diversity by ISSR analysis. The results could be summarized as follows.1. The vegetative propagation conditions of Lycoris aurea and L. radiate in vitro was studied by two-scaling. Different illuminate condition had an effect on the bulblet formation rate. To the species of L. radiate, the rate was higher in the state of 16h 800-12001x illumination than in the darkness. The medium also affected the new bulblet formating rate. When the culture was MS medium 0.2 mg/L NAA 4 mg/L 6-BA, the bulblet formationg rate of L. aurea was 220%;at the same time, when the medium was MS 0.2 mg/L NAA 2 mg/L 6-BA, the rate of L.

本研究选择西南部分地区及日本的几个石蒜品种，从细胞学和DNA分子角度，分析了它们的遗传多样性水平和遗传结构状况，对红花石蒜和忽地笑的离体繁殖技术进行了初步研究，得出如下结论： 1 进行了红花石蒜和黄花石蒜双鳞片快速繁殖条件的研究，结果表明：红花石蒜在16小时800-1200 lx光照下比黑暗条件下出芽率要高；黄花石蒜在MS NAA0.2mg／L 6-BA4mg／L下出芽率为220％，红花石蒜在MS NAA0.2mg／L 6-BA2mg／L下出芽率为108％；NAA比IBA有利于石蒜生根；硅藻土显著提高黄花石蒜双鳞片出芽率，活性炭起抑制作用；6％蔗糖浓度有利于红花石蒜小鳞茎增重，MS 6-BA4mg／L NAA0.5mg／L培养基有利于小鳞茎增殖，切割一刀比两刀有利于小鳞茎增殖。

By the nonlinearity of the propagation medium-air, the audible sound with high directivity can be produced.

利用超声波在空气中传播的非线性交互作用，可以产生高指向性的可听声音。

The apparent need for a propagation medium for such Hertzian waves can be seen by the fact that they consist of perpendicular electric and magnetic waves.

显然需要一个传播媒介等hertzianwaves可以看出的是，它们包括垂直电气及磁场热浪。
