Chilling requirements for breaking dormancy and heat requirements for flowering were studied in ten apricot cultivars in the region of Belgrade during a two-year period.Chilling requirements were determined using the Utah chill unit model(CU).To determine the date of dormancy breaking,one-year old shoots were collected weekly from December to February and put under controlled conditions.

天然产物是新药研究和开发的重要源泉。如何快速、有效和经济地分离和筛选出有活性的天然产物是当前药学研究的重要内容。本论文以丹参和穿心莲两种我国传统中药为对象,发展了几种有效的新的CCC分离方法,为逆流色谱在天然产物分离中的广泛应用提供理论基础和依据。溶剂体系的选择是逆流色谱分离成功与否的关键。但是,长期以来,对逆流色谱溶剂体系的组成还处于探索阶段,很少知道其确切的组成,这为其适用性和仪器推广带来了困

甲醇羰基化醋酸工艺技术是当今国际上先进的醋酸生产技术，该技术在国内开发的较迟，但由于其原料来源于煤，符合我国煤多油少的资源优势，且成本较其它工艺方法低，目前已成为国内醋酸
橄榄石型LiFePO_4因理论比容量高、资源丰富、对环境友好、安全性能突出、循环性能稳定等优点而被认为是新一代锂离子电池正极材料。但纯LiFePO_4因其电子导电率低和Li+扩散速率低而影响其电化学性能。通常采用减小粒径尺寸、添加导电剂和掺杂离子等方法来改善材料的电化学性能。本文采用水热法合成橄榄石型LiFePO_4，在水热反应前驱溶液中直接引入碳源制备LiFePO_4/C复合材料，对水热产物进行
