impulse labelling

用法例句

Three levels of N fertilizer were prepared:0(no nitrogen), 150(low nitrogen)and 300 mg N·kg-1(high nitrogen), and four growth stages of wheat plant were chosen for pulse-labeling with exposure to 13CO2 in 6-hour for each.

通过盆栽试验,研究了不同施氮0、150和300mgN·kg-1水平下,冬小麦光合产物的分配和根系碳淀积量,分别在苗期、拔节期、花期和灌浆期用13CO2脉冲标记6h,标记6h后和生育期结束后破坏性取样,测定冬小麦地上部、根、土壤和土壤呼吸中的13C含量。

4 times of(()~(13)C) pulse-labelling were used to estimate the photosynthesized carbon distribution at different development stages(seedling,elongation,heading and grain-filling) in maize-soil system,and quantify the carbon inputs into each part of belowground in whole growth season.

应用4次13C脉冲标记对不同生育时期(苗期、拔节、抽雄和灌浆期)玉米光合碳在玉米-土壤系统中的分配特征进行了为期1个生长季的研究。

In teletypewriter applications, the uniform shifting of the beginning of all marking pulses from their proper positions in relation to the beginning of the start pulse.
