Firstly, baculovirus is a key component of insect baculovirus expression system ( BEVS), which is being increasingly used in gene engineering for the research and development of new medicine and vaccines.

首先，杆状病毒是昆虫杆状病毒表达系统的核心部分，该系统已在药物研发、疫苗生产等方面得到广泛应用。

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.

综合阐述了昆虫杆状病毒表达载体表达外源基因的原理、技巧和进展，为该领域的进一步研究奠定基础。

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。
