轮型混价钼簇的电化学合成和性质 |
| 2. | Effect of root - zone hypoxia on no3 - n , nh4 - n and protein contents of muskmelon seedlings
铵态氮和蛋白质含量的影响 |
| 3. | Characteristics of nh4 and no3 - uptake by rices of different genotypes
不同水稻品种对铵态氮和硝态氮吸收特性的研究 |
| 4. | The electrosteric stabilization of pmaa - nh4 plays a important role in dispersion
这主要利用了pmaa - nh _ 4的电空间稳定机制。 |
| 5. | The electrosteric stabilization of pmaa - nh4 play a important role in dispersion .
这主要是利用了pmaa - nh4的电空间稳定机制。 |
| 6. | After urea application , there are more nh4 + than no3 - in the water surface
尿素施用后，田面水中以铵态氮为主，硝态氮比例较少。 |
| 7. | Yeast extract wbs the best nitrogen source in liquid culturate , the second was ( nh4 ) 2so4
在液体培养中，病菌对氮源的利用以酵母膏为最好，其次为( nh4 ) 2so4 。 |
| 8. | The main form of n leached was urea - n , next was ncv - n ; the proportion of nh4 + n leached was very low
与浇灌施肥相比，滴灌施肥显著地降低了氮素的淋溶损失。 |
| 9. | This is not the same as the views of " the concentration of no3 - is more than that of nh4 + ' s "
这不同于“地表水体中硝态氮的浓度远远大于铵态氮浓度”的看法。 |
| 10. | But the concentration of nh4 + decreased to the very low level in 7 - 10 days after fertilizer was applied
而田表水层中铵态氮浓度在施肥后第7 ? 10天左右均降至很低水平。 |
