The experimental results shows, if the ratio between MS-1 and OP-10 rangs from 1:1 to 3:l,and the total dosage of them is about 20% of Octamethylcyclotetrasiloxane (D4 ) in quality, we can obtain a kind of stable seeded emulsion of organic silicone modified acrylic ester emulsion. At the same time, if the ratio between MS-1 and Tetramethylammonium Chlorideis l:1.7,the total dosage is about 50% of D4 in quality; the ratio between MS-1 and Cetyltrimethylammonium Chlorineis 7:1, the total dosage is about 25% of D4 in quality,we can also obtain stable seeded emulsions. But if the complex emulsifier system is made of TMAC and OP-10, MS-1 and Peregal O or CTAC and Span-80, we can not synthesize any kind of satisfactory seeded emulsions.

实验结果表明：当MS-1与OP-10的质量比为1：1～3：1，总用量为八甲基环四硅氧烷(D_4)的20％左右时，可合成稳定性良好的硅丙种子乳液；MS-1与四甲基氯化铵的质量比为1：1.7，总用量为D_4的50％左右，MS-1与十六烷基三甲基氯化铵的质量比为7：1，总用量为D_4的25％左右时，亦能得到稳定的硅丙种子乳液；而TMAC与OP-10、MS-1与Peregal O以及CTAC与Span-80的复合体系作为乳化剂时均不能得到满意的硅丙种子乳液。

The scope of Tilia miqueliana is limited in Mahuangkeng of Taohua Island and Maocaowulengkeng of Damao Island.

南京椴Tilia miqueliana分布范围更是有限，主要分布在桃花岛蚂蝗坑和定海区大猫岛茅草屋冷坑，呈群落分布，共有结果母树170余株，每年种子产量极少，能采到的种子只有0.25 kg左右。

In the present study, efficient identification methods for the main varieties of cowpea (Vigna unguiculata W.) and cauliflower (Brassica oleracea L.) in south of China, especially in zhejiang province, were investigated by using seven cowpea varieties (variety 1, Zhijiangtechang80;variety2, Zhijiangtechang90;variety3, Qiujiang512;variety4, Zhijiang228-2;variety5, Huajiang24;variety6, Yangjiang40;and variety7, Xingaochan8) and five cauliflower varieties (variety A, Longfenteda50tian;variety B, Yidaijinguang80tian;variety C, RuixuetedalOOtian;variety D, Qiuwang80tian;and variety E, Tezao50tian). The application of seed shape, seedling shape, rapid chemical identification and electrophoresis was performed, the main results were as follows.

为开展南方特别是浙江省主要蔬菜作物种子高效快速鉴定技术研究，本试验以七个豇豆品种品种1(之豇特长80，品种2(之豇特长90)，品种3(秋豇512)，品种4(之豇228—2)，品种5(华豇24号)，品种6(扬豇40号)，品种7和五个花椰菜品种品种A(龙峰特大50天，品种B(一代金光80天)，品种C(瑞雪特大100天)，品种D(秋王80天)，品种E(特早50天)为材料，从种子形态、幼苗形态、快速化学和电泳鉴定等方面对豇豆和花椰菜品种鉴定进行了研究，特别是对乳酸—聚丙烯酰胺凝胶电泳在这两种蔬菜品种鉴定上的可行性进行了研究。

From green up stage to withering stage, the percentage of Leguminosae, Gramineae, and Violaceae decreased and however, the percentage of Compositea and Labiatae increased greatly.
