以7片段拼接的水稻单交换质体定点整合表达载体pRSMGA的构建为例，应用上述方法构建只需做两次连接、转化，且其重组、转化效率高。

In this paper, with field experiments the allometry relationship between plant height and biomass of annual plants, Avena sativa and Vicia sativa, under low density and high density, were investigated, and the data obtained from experiments were analysed with the linear and nonlinear regression.

通过田间试验研究了两种一年生植物燕麦和箭豌豆在高密度和低密度条件下表现出来的株高与生物量之间的异速生长关系，并用线性回归和非线性回归的方法对所得数据进行了分析。

Miao is well-known for their use of various wild fibers. In Miao' s daily life, on the one hand, Cannabis sativa L. becomes a medium between Miao and the natural environment with the development of traditional processing technologies; on the other hand, clothing made of Cannabis sativa L. is often regarded as gift exchanged between different individuals and clan members in certain occasions. Meanwhile, it can also be used as a kind of commodity in exchange of grains and other daily necessities in market.

苗族原来就有着长期使用各种野生纤维的传统，自从麻进入苗族的生活中以后，一方面，通过苗族刀耕火种传统知识的加工改造，火麻充当了苗族与自然界进行能量交换的中介物；另一方面，用火麻织制的麻布及服饰，往往被选择作为礼物，被不同个体和宗族成员在一些特定场合下相互赠送，同时也充当商品，从市场换取粮食和其他生活用品，是个体与社会进行多个角度，多个层次的连接和转换的媒介物。

Cannabis sativa L., named "Huo Ma" by Miao society of Yunnan province, is a kind of material for foodstuff, fiber and drugs.It has once played an important role in Miao people's life, but now the cultivation has declined due to prohibition of drug abuse, and the whole set of traditional knowledge centering on Cannabis sativa L.
