而mgci :和cac12处理下叶片细胞汁液中na +浓度都与对照相似。不同盐处理下，叶片细胞汁液中cl一浓度也不同。 - After that , cld of al2o3 is carried out through a system equipped with a teflon vessel immersed in a water bath . the chemicals used to make growth solution include al2 ( so4 ) 3 . 18h2o , nahco3 and deionized h2o
然后，通过一套包括浸在水浴装置中的聚四氟乙烯生长室的实验装置系统，我们完成了化学液相淀积氧化铝薄膜的实验过程。 - 5 , south region oil has the feature of " three high and one low " , the stratum water is type nahco3 , and plane distribution is affected by gravity differentiation and faults , which caused each fluid block separating into individual
5 、南区原油具有“三高一低”的特征，地层水为n司hco3型，平面分布主要受重力分异作用以及断层的影响，导致各断块流体自成体系。 - The polysaccharide production were 37 . 296mg / l and 12 . 961mg / l . the best conditions for extracting polysaccharide from porphyridium purpureum were as follow : alcohol concentration was 75 % , alcohol volume was 2 - fold time , percolation time was 1h , the volume ratio of glycoprotein solution to sevag reagent was 1 : 2 , time was 45min and sevag reagent was 3 : 1 between chloroform and butanol . the result also indicate that nahco3 and nh4cl were the best carbonic and nitrogen sources for polysaccharide respectively
淡色紫球藻的最优提取工艺为乙醇浓度75 ，乙醇用量为2倍体积，醇沉时间为1小时；氯仿与正丁醇的比例3 ： 1 ，样液与sevag试剂的比例1 ： 2 ，作用时间为45min ：由方差分析可得五种碳源和五种氮源对胞外多糖的影响不显著，添加碳酸氢钠和摘要nhoci的多糖产率最高，分别为41 - The aim of this experiment was to show the characters that salt - alkaline mixed stress on plant and the correlativity between saline stress and alkaline stress . seedlings of sorghum ( changbang 128 ) were stressed with 28 kinds of mixed salt which were composed of nacl , na2so4 , nahco3 and na2co3 at various proportions and were different in salinity and alkalinity each other ( the range of total salt concentration 50 - 300mmol / l and ph 7 . 12 - 11 . 43 )
