The addition of F-/AcO- to 2 was further confirmed by monitoring the changes in its 1H NMR spectra in the presence of either F- or AcO-(Figure 3). Four peaks of acridinium of 2 showed pronounced upfield shifts due to the conversion of acridinium to acridane in 5 equiv of either F-(Figure 3b) or AcO-(Figure 3c).

F－/AcO－添加到2中通过监测其在存在F－或AcO－时H NMR谱的变化进一步得到确认（图3）。2的吖啶盐的四个峰值证明了由于在5个当量F－（图3b）或AcO－（图3c）中吖啶盐转化成吖啶而引起的明显的高场位移。

The changes of Cr and Fe concentration were measured during Co-culture experiment and slurry experiments. The microbial reducing ability of different chromate concentrations and the effect of chromate on dissimilatory iron reduction in paddy soil were investigated.

通过接种土壤微生物的混合培养及土壤泥浆培养试验，测定了厌氧培养过程中Cr和Fe浓度的变化，研究了不同浓度铬酸盐的微生物还原能力及不同浓度铬酸盐对水稻土中氧化铁还原的影响。

The Co-culture experiment and slurry experiments were applied to two paddy soil samples, which from Sichuan and Jiangxi provinces. The concentration varying of Crand Fe was measured in the course of incubation to study the chromate reducing capability of microbe and effect of chromate on dissimilatory iron reduction .

采用四川和江西水稻土为供试土壤，通过接种土壤微生物的混合培养及土壤悬液培养试验，测定厌氧培养过程中Cr和Fe的浓度变化，研究了不同浓度铬酸盐的微生物还原能力及不同铬酸盐浓度下氧化铁的还原能力。

In this work , 1,8-octodiol, the starting material, reacted with 40% hydrobromic acid to produce 8-bromooctan-1-ol, with the catalytic action of PPTs, its hydroxyl group was protected by 2,3-dihydropyran. Then it coupled with 1-heptaalkyne, by means of P-2 nickel as catalyst, stereoselectivity catalysis hydrogenated, with the catalytic action of acid to take off extremital 2, 3-dihydropyran which protected hydroxy group, then used PCC to oxidize alcohol into corresponding aldehyde.
