2016/12/9
Short rotation coppice (SRC) plantations of fast growing trees in Czech Republic may be grown on approximately 120,000 ha in future, as indicated in the Czech Action Plan for Biomass. Until now, 2,800...
芦笋秸秆预处理与厌氧发酵制取沼气试验（Experiments on Pretreatment and Anaerobic Digestion of Asparagus Stalk for Biogas Production）
芦笋 秸秆 厌氧发酵 沼气
2010/12/28
为了促进芦笋秸秆原料沼气发酵系统的产气效果，利用NaOH在无流动水的条件下对芦笋秸秆进行了碱性化学预处理，并在小型沼气发酵装置上以不同预处理时间、粒径和NaOH溶液质量分数对芦笋秸秆木质纤维素的变化及产沼效果的影响进行了试验研究。结果表明，预处理时间15~20d比不经预处理的试验组启动时间提早10d；芦笋秸秆粉碎和切割后，不经筛分的试验组比经过筛分后的试验组启动时间提早5~15d，发酵周期缩...
面条复合改良剂用量的响应面法优化（Optimization of Improvers for Noodles Production Using Response Surface Methodology）
瓜尔豆胶 磷酸酯淀粉 三聚磷酸钠
2010/12/28
选取瓜尔豆胶、磷酸酯淀粉及三聚磷酸钠为自变量，面条弹性和韧性为响应值，采用Box-Behnken设计的方法，研究各自变量及其交互作用对面条弹性和韧性的影响。利用响应面分析方法模拟得到弹性和韧性二次多项式回归方程的预测模型，确定面条改良剂的最佳添加量（质量分数）为：瓜尔豆胶0.70 %，磷酸酯淀粉5.50%，三聚磷酸钠0.15%，此时面条的韧性为790.71 g?mm，弹性为38.18g。
