Expounds principle, technique and development of insect baculovirus expression vector system ( BEVS) that can express foreign gene in a systematic way, which lays a foundation in this field.

But the frequency of recombination was very low ( 0.1%-1%) and it limited further application of the baculovirus expression vector system ( BEVS).

但由于重组病毒产生的比例很低（通常只有01%～1%），成为制约该系统应用的技术瓶颈。

The principal contents of this thesis including: ( 1) expression of the full-length PPAR γ by BEVS.

论文的主要内容包括：（1）利用杆状病毒表达系统表达全长核受体PPARγ。

Insect baculovirus expression vector system ( BEVS) is a super high-level eukaryotic expression system developed in 1980s.

杆状病毒表达系统是80年代发展起来的超高效真核表达系统，家蚕杆状病毒表达系统比普通杆状病毒表达系统又具有其多种特有的优势。

The term, which is primarily used in reference to battery electric vehicles ( BEVs), is considered to be one of the major barriers to large scale adoption3 of all-electric cars.

这个词主要用在电动汽车领域，“里程焦虑”也被认为是纯电动汽车被广泛接受面临的主要障碍之一。

BEVS is a lytic expression system. There are several proteinase coded by the BmNPV itself.

杆状病毒表达系统是一个裂解性的系统，杆状病毒本身具有多个蛋白酶基因，在表达目的基因产物的同时，这些蛋白酶也得到了表达。

today he is chairman of Octea, which is the holding company for Koidu, and a diamond mining subsidiary owned by Beny Steinmetz Group the natural resources company founded by the eponymous Israeli businessman.

如今，他是Koidu的控股公司Octea的董事长。Octea是贝尼斯坦梅茨集团（Beny Steinmetz Group）的钻石开采子公司，这家集团是由以色列商人贝尼•斯坦梅茨（Beny Steinmetz）创办的自然资源公司。

The levels of nutrient solution, corn, and soybean had significant effect on stalk degradation ( P0.05). ( 4) Substitution method and emptying-force-feeding method were used to determine the apparent metabolic energy of BFCS separately.

其中营养液、豆粕和玉米的不同水平对纤维素的降解率有显著的影响（P0.05）。（4）分别采用套算法和强饲法测定生物秸秆肉鸡的表观代谢能。

BEPI was hydrolyzed in the excess sodium hydroxide into a tetrasodium salt, and then acidified into bisphenol A type diether tetraacid ( BPDETA, yield: 97.3%, melting point; 198.5~ 201.5 ℃) with sulphuric acid.

再在过量氢氧化钠的作用下水解BEPI，使之生成四钠盐后，酸化处理得到双酚A型二醚四羧酸（BPDETA），收率为97.3%，熔点为198.5～201.5℃；

The model about net ecosystem production applied remote sensing ( NEPARS) was build here based on Biome-BGC and BEPS model. The model was applied to estimate carbon budget at different spatial scale: the Northeastern China and the main land of China.

本文在Biome-BGC模型和BEPS模型基础上，构建了应用遥感数据的陆地净生态系统生产力模型（NEPARS），并分别以我国东北地区和全国为例，进行了模拟研究；

The rules, called "base erosion and profit shifting" or Beps, are designed to close loopholes and restrict the use of tax havens.

这些被称为“税基侵蚀和利润转移”（base erosion and profit shifting，简称Beps）的规则，旨在堵住漏洞和遏制利用避税天堂的行为。

The main remote sensing process model ( CASA, BIOME-BGC and BEPS model) are studied and discussed. The advantage and main problem of these models are discussed.

通过3种主要的遥感过程模型（CASA、BIOME-BGC和BEPS模型）进行阐述和分析，探讨了这几种模型的优势和主要存在的问题。

Then the paper discussed the system requirements of BEPS, and described the functions of each subsystem definition and business processes in the BEPS.

之后介绍了系统的需求分析，详细描述了各子系统的功能定义和业务流程。
