  • 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。
  • Optimum water pricing is the key point . in this paper , the structure of water value and water price , the characteristics of water resource , and how they affect water pricing have been discussed . the paper ' s chapter 1 is introduction
    本论文主要探讨了水资源商品的价值和价格构成,水资源商品不同于一般商品的特性对水资源商品价格的形成所产生的影响,以及能够体现水资源价值的水价计算方法。
  • 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。
  • Aiming at the present low efficiency of well irrigation works and through pumping tests and theoretical analysis , the paper derives a method for calculating the optimum water yield , the best lifting distance and economic pipe diameter of low pressure pipe delivery system of irrigated area by wells , increasing the efficiency of motor - pumped wells
