PCR 技术扩增目的基因（ 1）原理： DNA双链复制（ 2）过程：第一步：加热至 90 95DNA解链 。其次步：冷却到 5560, 引物结合到互补 DNA链。第三步：加热至 7075, 热稳固 DNA聚合酶从引物起始互补链的合成 。其次步： 基因表达载体的构建1. 目的：使目的基因在受体细胞中 稳固存在 ,并且可以 遗传至下一代 ,使目的基因能够 表达和发挥作用 。water conditions, gray trench cover under i nstallation conditions, must pass throug h the cha nnel t o temporary walkwa y, pool not instal led around the raili ngs to temporary fenci ng to preve nt persons falling residue. 5.1.9, t he dr um and t he expa nsion of the i ndi cator on the heade r, should dr um and set the box to check t he local installati on of temporary inflation indicator. 5.1.10, the wall built after the manhole, inspecti on door shoul d be ope ned for natural dryi ng. 5.1.11, choosi ng a furna ce wall temperature measur ement points a ccording t o the req uirement s and sampli ng poi nts temperat ure measuri ng points wit h the following l ocation: 1.5mm-2.0mm above the com busti on chamber side w all furna ce non-Ce ntral Office, at the outlet of the fur nace, and economizer exit flue, middle of ba ck wall. 5.1.12 bel ongs a ll valve tone, boiler system, and the name is correct. 5.1.13, boiler feed -water front open drum air doors, to empty the ex haust valve a nd traps the super heater hea der, injecte d into t he boiler after treatment and softeni ng water to dr um zero meter level, glass tube level gauge should be clear a nd corre ct. 5.1.14, a cres of fine fuel s such a s wood, coal, fue l must not be mixed with ir on class st uff. 5.1.15, a ccording t o prepare d baki ng pr ogramme, to technol ogy to giv e可编辑资料 - - - 欢迎下载精品名师归纳总结1, and prepare d accordi ng to 1.1, and thermal power e ngine ering started debugging w ork provi des 1.2, a nd thermal power pow er plant construction engi neering started and the complete d accepta nce procedures 1.3, and thermal power unit started steamBlow pipe guide is 1.4, and thermal powe r engineeri ng adjustment try shipped quality test and the eval uation standard 2, a nd # 1 furna ce started debugging orga nization measures and the relate d provi des 2.1, and organi zation Divisi on: for g uarantee wi de up thermal power plant #1 fur nace started de buggi ng and the part steam machi ne system of smooth vote d shipped, spe cial establi she d #1 fur nace try shipped professi onal gr oup, members foll owing: l eader : Deputy Lea der: supe rvision: cr ew: wi de up try shi ppe d personnel: wi de up acce ptance personnel: 2.2, a nd debugging, a nd try shipped conte nt: boiler a uxiliary machine Divi sion debugging el ectric dust of Division try turne d and the debugging baking furnace Cook furna ce boiler r ushed tube, a nd bl ow sw eep security door check 2.3, and operation provi des a nd the Divisi on: # 1 furna ce de buggi ng, a nd try shi pped by #1 fur na ce try shi ppe d professional group requirements for, whi ch single try tur ned a nd Divi sion try shi ppe d by xD three compa ny led is re sponsible for. all moving o peration operation m ust be i n strict a ccordance wit h the pri or aut horizati on of the #1 boiler commissi oni ng professional worki ng group, and after starting, the test command-approved #1 fur nace steps in the test programme, event of temporary cha nges be reported to headq ua rters approval. commissioning, trial operati on pr oce ss is re quire d for each project by Northw est electri c power constr uct on compa ny ready "equipment i nstallation records", a nd fill in t he test applicati on form, the a a nd b side s after passi ng the che cks, fill in "partial commissioning che cking before a visa", reporte d hea d of the approval, carried out by the leader of unified command.
