On determination of optimum water content of lime - treated expansive soil
石灰改性膨胀土施工最佳含水率确定方法探讨
Effect of water content on cell viability at an average dehydration rate of 0 . 9 % water content / h , water contents in beads had more effects on cell viability after dehydration than after thawing . different algae have various optimum water contents
结果表明：（ 1 ）含水量对藻细胞存活率的影响以0 . 9 %含水量/ h的脱水速率脱水，胶球含水量对脱水过程的存活率影响不大，但对冰冻保存的存活率影响很大。
Effect of dehydration procedure beads of pavlova viridis were desiccated with four different procedures . two dehydration rates were used , which are 0 . 9 % water content / h ( slow ) and 10 % water content / h ( rapid ) . resul - ts showed that slow dehydration is the best . a dehydration combination of rapid dehydration to 70 % water content , followed by slow dehydration to the optimum water content is a better procedure . rapid dehydration is the worst
（ 3 ）脱水程序的影响以绿色巴夫藻为研究对象，选择0 . 9 %含水量/ h （慢）和10 %含水量/ h （快）两种脱水速度，分两步脱水，先脱水至70 %含水量再脱水至最佳含水量。结果慢-慢程序脱水，存活率最高；快-慢程序其次；快-快程序最低。
