| 1. | Wet desulfurization of cog using na2co3 as alkali source and
3为碱源的脱硫技术 |
| 2. | It was shown that na2co3 inhibited the pitting corrosion of aluminum alloy to some extent
实验结果表明，碳酸钠对铝合金具有较好的缓蚀作用，在一定程度上抑制了铝合金的点蚀。 |
| 3. | All of these mean that suaeda salsa can resist nacl stress effectively but can " t resist na2co3 stress effectively
这些都表明，碱蓬的耐盐性较强而耐碱性较差，即碱害大于盐害。 |
| 4. | Overabundant ros aggravated the injury to suaeda salsa and decreased its resistance ability to na2co3 stress
在ndico3胁迫下，不但na十区域化能力小，而且叶片内的na十含量也大于nao胁迫。 |
| 5. | Under na2co3 stress , the content of proline increased , so proline must be a kind of buffer in suaeda salsa
Cos胁迫使na k十比增加的幅度都大于naci胁迫，即产生的离于不均衡现象更严重，这是ndico 。 |
| 6. | On the whole , the ability of resistance to na2co3 stress in suaeda salsa was less than that of nacl stress . the reason for this is concerned with many aspects
所以我们可以断定，在nz 0 。胁迫下，细胞质内的才含量一定大于naci胁迫，由此形成的na十毒害也大于naci胁迫的。 |
| 7. | But more energy will be used if the plant depends mainly on the organic osmotica to regulate its osmotic potential . this is another reason which made suaeda salsa ca n ' t resist na2co3 stress effectively
然而，植物用有机物来进行渗透调节所消耗的能量比用无机离子多得多，这也是在na _ 2co _ 3胁迫下碱蓬生长受抑的又一原因。 |
| 8. | Compared with nacl treatment , under na2co3 stress , the organic osmotica played a more important role in osmotic regulation of suaeda salsa which maybe resulted from the adaptive reaction to high ph value
和nacl处理相比，在na _ 2co _ 3胁迫下，有机物所起的渗透调节作用大于nacl处理，这也许是碱蓬为适应高ph环境而作出适应性反应的结果。 |
| 9. | So the ability of scavenging reactive oxygen species ( ros ) was enhanced and the injury caused by ros was alleviated . on the contrary , under na2co3 stress , the activity of sod decreased which made the ros can not be scavenged timely
在ndsco3胁迫下，玉米叶片内的v h “ atpase和v h ” ppase的水解活性虽然也增加，但增幅小于naci处理的，这就限制了玉米na十区域化能力的提高。 |
| 10. | The main results of the experiment are as follows : 1 the comparison of the stress effects of nacl and na2co3 on suaeda salsa l . the growth of suaeda salsa could be promoted by certain concentrations of nacl but inhibited markedly by na2co3 the change in root vitality was not significant under nacl stress but significant under na2co3 stress
1nacl和na _ 2co _ 3对盐地碱蓬胁迫效应的比较300mmol l以下的nacl能促进碱蓬的生长，而na _ 2co _ 3在浓度不很大时就能显著抑制碱蓬的生长。碱蓬在nacl胁迫下根系活力变化不显著，但在na _ 2co _ 3胁迫下，碱蓬根系活力则显著下降。 |
