According to the conserved regions of other known insects, a pair of specific primers were designed and the RT-PCR method was used to amplify the partial sequences of HSP70 from cotton aphid, then analyzed the nucleotide and deduced amino acid sequence.

根据已知昆虫HSP70基因的保守性区域，设计特异性引物，采用RT-PCR方法扩增棉蚜HSP70基因的部分序列，测序后进行核苷酸和推导的氨基酸序列分析。

In this research we increased the backsights from 3 to 10 points.and observed 5 sets of VRS,1 set of static GPS,5 sets of 3D LASER. we considered the Static GPS as the standard observation set,and compared it with the VRS's coordinates after adjustment.The RMS and the range of differences are taken as the indicator of accuracy .

一般而言，3D LASER作业只须三个已知点即可定得绝对坐标，为了增加多余观测量，本研究将3个后视点增加为10个后视点，针对这10个后视点分别施测5组VRS、1组静态GPS、及5组3D LASER，文中以静态GPS为对照组，以改正前后之VRS坐标与静态GPS坐标较差之RMS及分布范围为精度分析之指标。
