解釋
基地核防護能力硬度-
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。 -

The result shows that tempered martensite has apparent lath character when temper is between 740 ~ 780, and the hardness of welded joint is 264 ~ 237hv, which can get better performance of the welded joint the lath character of martensite in welded joint disappears, and the carbide in the tempered sorbite of the base metal will aggregate when temper temperature is above 780, and the hardness and plastic property will reduce obviously
結果表明，在740 ~ 780之間回火，焊縫硬度為264 ~ 237hv ，回火馬氏體板條特徵明顯，可以獲得優良的焊接接頭性能；回火溫度超過780 ，焊縫板條馬氏體特徵消失，母材回火索氏體中碳化物產生偏聚，硬度、塑性明顯降低。 -
