您要查找的是不是：
- Chla活体值 active value of Chla
- Chla萃取值 extraction value of Chla
- 叶绿素A(Chla)溶液发光同浓度的关系 RELATIONSHIP BETWEEN THE LUMINESCENCE AND CONCENTRATION OF CHLOROPHYLL A (chla) SOLUTION
- TSI(SD)、TSI(TP)都大于50,TSI(chla)小于50; TSI(SD) and TSI(TP) was both more than 50,TSI(chla) was less than 50;
- 而栓皮栎的叶绿素含量在第33d后大幅降低,Chla/Chlb的比值下降。 The chlorophyll content of cork oak steadily declined from the 33rd day and the Chla/Chlb ratio also deceased.
- NaCl、Na_2SO_4胁迫下,大果沙枣叶片的叶绿素a、b、a+b含量有所变化,其变化不平稳,Chla/b随盐浓度的升高而升高。 Under NaCl and Na2SO4 stress, the Chl(a,b,a+b) connent in Elaeagnus mooraroftii leaves had difference changes, but the ratio of Chla/b increased after increasing salt concentration.
- 突变体W1白化苗中的Chla和Chlb含量同时下降 ,Caro Chl的比值增大 ,说明该突变体属于不是由Caro降低而导致的总叶绿素缺陷型。 The decrease of Chl a and Chl b at the same time and the increase in the ratio of Caro/Chl in albino seedlings showed that the mutant W1 belonged to the total Chl deficient type that was not caused by the decrease of Caro content.
- 对镜湖水质富营养化的研究结果表明 ,镜湖水体溶氧丰富 ,五日生化需氧量 (BOD5)、化学需氧量 (COD)、总磷 (TP)、总氮 (TN)、叶绿素a(Chla)严重超标。 This paper investigated the trophic state of mirror lake. It shows that DO is abundant and BOD5,COD,TP,TN,Chla are very high in comparison with the standard value for water.
- 6 Na2SO4盐胁迫下，叶绿素(Chl)含量降低，但Chla/b升高，表明狗牙根在以Na2SO4为主的较重盐碱地上可通过提高Chla/b比值促进光合作用，降低盐分对其生长的抑制。 6 Chl content was reduced with the increasing salt concentration, but Chla/b was increased, as show Bermudagrass could decrease the restraint of growth by raising Chla/b.
- pH、透明度(SD)、总氮(TN)、总磷(TP)、生化需氧量(BOD)、化学需氧量(COD)、叶绿素a(chla)的营养状态指数综合评价表明，密云水库水体为中营养型，并且出现了向富营养发展的趋势。 General tropic state index of PH, SD, TP, TN, BOD, COD and chla suggests that water body of Miyun Reservoir already belongs to middle nutrition and there is the tendency to eutrophicate.
