叶绿素

The value of POC/chl a in Prydz Bay is higher than that in other areas but similar to the value in Ross Sea.

POC与叶绿素 a的高度相关性(r=0 。889，n=91 )表明普里兹湾 POC主要由 POCB组成即主要来自于浮游植物的贡献。

Effects of H〓O〓 and MV on chlorophyll fluorescence parameters in different chilling-tolerant cultivars After rice seedlings were treated with H〓O〓 and MV, Fo in both cultivars decreased, whereas qNP rose.

然而，对正常培养的水稻幼苗进行3d的高磷处理，常温和低温下，两品种色素含量、光合速率和光呼吸速率接近对照水平，叶绿素荧光参数也没有明显差异。

And 67. 5% in Xiangnuo 1 and IR50 respectively when they were under chilling for 2days. Chlorophyll fluorescence data showed that the reaction centers with less accumulation of redundant exciting energy and antenna systems in Xiangnuo 1 were less injured under chilling, with higher qP and qNP which were used to dissipate the redundant exciting energy, and protect the reaction centers from chilling injury. Lower qP and higher Ex as well as decreasing qNP in chilling-susceptible cultivars indicated that its reaction centers and antenna systems were damaged severely by chilling, leading to the lower photosynthetic rate.

叶绿素荧光分析的结果表明，低温下湘糯1号PSII反应中心和天线系统受到的伤害轻，反应中心过剩激发能积累少，可藉较高的qP和qNP进行过剩光能的耗散，保护光合机构免受低温伤害，而冷敏感品种qP下降快，Ex增加较多，但qNP却随低温延长而下降，说明它的反应中心和天线系统都受到了严重的低温伤害，导致光合能力下降。

Water column samples taken from the northern and the southern lake centers in Hongfeng lake in summer stratification were measured about their water temperature, pH, the concentration of HCO3(superscript -), DO, Chla, NH4(superscript +), NO3(superscript -)、and PO(superscript 3- subscript 4). The pressure of CO2 (pCO2) was calculated by the chemical balance and the Henry's law.

在夏季分层期间对红枫湖南、北湖湖心的水样进行分层采集，同时测定了分层水样的温度、pH、HCO3浓度、溶解氧、叶绿素a及铵根离子NH4(上标+、硝酸根离子NO3(上标-、磷酸根离子PO(上标 3-下标 4的浓度，水体中CO2的分压(pCO2)由化学平衡及亨利定律求得。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
