Degenerate oligonucleotides to highly conserved regions of cucumis melo 1 - aminocyclopropane - 1 - carboxylic acid ( acc ) oxidase gene were used to prime the amplification of fragment of 128bp by ploymerase chain reaction ( pcr ) in samples of genomic dna from fruit of cucumis melo l. cv hetao flesh, which was cloned into plasmid vector pmd - 18 - t. the clon of antisense orientation were selected, and it was inserted downstream of camv35s promoter and enhancer " " of tmv into the plant expression vector pbinyxw, antisence expression vector pbinya was constructed. at the base that pollination and fertilization of cucumis melo l. cv hetao was studied, using pollen tube pathway transformate cucumis melo l. cv hetao, 76 fruit had been obtained, moreover, hardness and content of sugar were analysed
本實驗以河套蜜瓜果肉基因組dna為模板，用甜瓜acc氧化酶基因特異寡核苷酸鏈為引物進行pcr擴增，得到128bp的擴增產物。將得到的擴增產物克隆到質粒載體pmd - 18 - t上，篩選反向克隆，然後將其反向構建到植物表達載體pbinyxw的camv35s啟動子和tmv增強子「 」的下游，構建成反義表達載體pbinya 。並在對河套蜜瓜授粉受精生物學研究的基礎上，通過花粉管通道法轉化河套蜜瓜，共獲76顆瓜，並進行了硬度和含糖量的分析。 -
We find that the relations between the electronic effective mass of lowest - lying conduction band and wave vector are resemble, not only for narrow - gap semiconductor zigzag tubes but also for wide - gap semiconductor zigzag tubes. the electronic effective masses at bottom of lowest - lying conduction band depend on their tube - diameters
我們發現，無論是鋸齒型窄隙半導體管還是鋸齒型寬隙半導體管，同一類管的最低導帶的電子有效質量隨波矢變化的規律基本相同，且其導帶底的電子有效質量隨管徑的增大而減小。 -
Leading by the nc bend tube welding jig design flow, develop a series of tools in the cad software platform, then construct the nc bend tube welding jig cad system under the tools collection ; 2 ) use the reverse technology of nc bend tube ’ s modeling, aim to the most general nc bend tube, reevaluation the bend tube ’ s essential feature by using the vector transformation algorithm, and establish bend tube model above this foundation
論文的主要工作包括以下幾個方面: 1 ）提出了數控導管焊接夾具cad系統框架。在數控導管焊接夾具的設計流程引導下，于cad軟體平臺上開發系列工具集，進而在工具集支撐下構建數控導管焊接夾具cad系統; 2 ）應用了數控導管逆向建模技術。
