Using these diagrams, thermodynamic analysis is carried out to show the effect of technical conditions on soda decomposition of scheelite. It appears that the concentration of has direct effect on soda decomposition of scheelite. When the alkalinity is low, will hydrolyze to , accordingly the decomposition rate of scheelite becomes lower because of the decrease of . So in order to get higher leaching rate in industry practice, it is necessary to use enough amount of soda to serve as digestion reagent and, certain amount of NaOH to maintain high enough alkalinity.

利用这些热力学平衡图对Na2CO3分解白钨矿的工艺条件进行了分析，认为溶液中浓度直接影响白钨矿分解，而当碱度较低时，Na2CO3将水解生成，从而降低浓度，进而降低白钨矿的分解率；故在工业实践中，为使钨最大限度地转入溶液，除了保证足够的Na2CO3用量，还必需添加NaOH以维持一定碱度。

The tolerance of seawater fish Japanese sea bass and black rockf ishto pH and alkalinity is studied through the experiment of acute toxicity. The median lethal concentration values are obtained by the method of probability unit. The safe concentrations of alkalinity, C032- and HC03- are obtained. The signification of pH and alkalinity is estimated with analysis of variance.

本文应用急性毒性试验方法研究了海水鱼类鲈鱼黑鲪对pH、碱度、二氧化碳体系各分量的耐受性，应用概率单位法求得半致死浓度，并得到了碱度、碳酸根、碳酸氢根等的安全浓度，应用方差分析评价了pH和碱度致毒作用的显著性，探讨了不同pH、碱度范围的主要致死因子。

Result Activity of serum alkalinity phosphatase of cows and sheep was in a normal range. But activity of alkalinity phosphatase of mid pregnancy cows was obviously lower than before pregnancy and not pregnant and later pregnancy (P.05). Alkaline phosphatase retention was lower than 26%. It showed that serum alkalinity phosphatase of cows and sheep came from the skeleton.

结果］所有奶牛和绵羊血清碱性磷酸酶活性均在正常范围内，但奶牛怀孕中期的碱性磷酸酶活性比未怀孕、怀孕前期、怀孕后期明显降低(P.05)；碱性磷酸酶保存率均低于26%，表明奶牛和绵羊血清碱性磷酸酶均来自骨骼。

［目的］研究碳酸盐碱度对中华蟾蜍蝌蚪生长发育的影响，为其他水生生物的生长对碳酸盐碱度的适应性研究提供数据与参考。

The mount of germ and fungus quantity in soil are remarkably increased for the continuous cropping about 5 years, puts the trichobacteria quantity always change tendency to reduce;The edaphon total quantity, the bacterium quantity change reduces generally above the continuous cropping 5 years and below 5 years (including 5 years) the change are not obvious;In the nitrogen physiology group by ammoniates the bacterium primarily and the quantity changes are not very big;The nitrifying bacteria quantity is lower than the comparison (non- continuous cropping), the quantity of denitrifying bacteria is opposite;The alkalinity phosphatase, the urease, invertin activeness have a closed relations with the continuous cropping when it will increase less than 5 years or decrease in more than 5 years. The relation between catalase activeness and the continuous cropping is not very big. The reduction of the invertin activeness, the alkalinity phosphatase, urease activeness have slightly elevates, catalase activeness have no the regular changes.

表现为连作条件下土壤真菌数量显著增大，放线菌数量总的变化趋势降低；土壤微生物总量、细菌数量变化在连作5年以上普遍降低，5年以下(包括5年)则变化差异不明显；氮素生理群中以氨化细菌为主，但数量变化不大；硝化细菌数量低于对照组，反硝化细菌数量则相反：多酚氧化酶、转化酶活性在5年之前逐渐上升，5年之后逐渐下降，，脲酶活性随着连作年限增加持续上升，过氧化氢酶活性、碱性磷酸酶活性变化无规律。

When the alkalinity of soil with gypsum is as well different. The effciency is better with the siol alkalinity increasing.And the alkalinity is higer, the increasing scape is bigger.
