[ Objective] To determine the optimal supplement dosage of double-low rapeseed meal in concentrated feed of fattening lambs. [ Method] A total of 120 Tibetan lambs at the age of 50 d were selected and divided randomly into four groups. The lambs in these four groups were fed with diets respectively supplemented the double-low rapeseed meal of 50,100,150 and 200 g/kg. Their diets had the same nutritional levels of energy and protein. The experimental period was 120 d. [ Result] Daily gain, feed conservation ratio and economic benefits were largely increased in the lambs fed with the diets supplemented the double-low rapeseed meal of 150 g/kg （Daily gain, P 〈 0.01 ）. However, the daily gain and feed conservation ratio were largely decreased in the lambs fed with the diets supplemented the double-low rapeseed meal of 200 g/kg. Moreover, serum levels of transaminase and thyroxine were not significantly different between the four groups. [ Conclusion] The optimal supplement dosage of the double-low rapeseed meal is 150 g/kg in fattening lambs.

In Yuqia Basin, the climate is arid and the ecologic environment is fragile, and shortage of water resources has seriously restricted the sustainable development of local economy. In order to meet the needs of industrial and domestic water in the Yuqia Basin, numerical simulation was used to evaluate the groundwater resources and potential for exploitation. The results showed that the mathematical model and calculation parameters used were mainly in accordance with practical situation. The calculated value of the underground water level is consistent with measured value during the period of identification and validation. The total recharge of groundwater resources was 22.02×10~4 m^3/d, and the total drainage was 21.95×10~4 m^3/d at present. The Yuqia River leakage is the main supply source of groundwater. There is no significant effect on area of wetland when water source place exploited by 2.5×10~4 m^3/d at alluvial-diluvial fan of Yuqia River. After long-term exploitation, the spring flow reduces from 1.42×10~4 m^3/d to 1.01×10~4 m^3/d and wetland area reduces by 32.7% of original area. The calculation of water balance shows that it is safe to the Yuqia Basin, Da Qiadam Lake, the Mahai Basin at downstream of Yuqia River and wetland under the condition of water source place exploited by 2.5×10~4 m^3/d.

中国古典小说并不是沿着历史演义、英雄传奇、神魔、人情小说的叙事轨迹平行发展的,而是呈现出彼此之间的混类现象。《水浒传》在怪、力、乱、神方面对《封神演义》的创作有深刻的影响,座次表就直接孕育了封神榜。

以氯甲基化大孔聚苯乙烯-二乙烯苯交联树脂(PS)为载体与叔胺进行季铵化、与磷钨杂多化合物离子交换制得了PS接枝季铵磷钨杂多酸盐催化剂。对催化剂进行了FT-IR、XPS和BET分析,并将催化剂用于无搅拌条件下的相界相转移催化环辛烯双氧水环氧化反应;讨论了催化剂结构、催化剂用量、双氧水质量分数、双氧水和环辛烯摩尔比、反应温度等因素对反应的影响。结果发现具有三乙醇胺结构的催化剂因亲水性较强处于下层水相而不能用于相界相转移催化反应;而具有长直碳链季铵盐结构的催化剂因具有合适的亲水性和亲油性,能处于环辛烯和双氧水的界面处,可用于无搅拌情况下的相界相转移催化反应。室温下环氧环辛烷的产率可达99%以上;提高反应温度、双氧水质量分数等可明显提高反应速度。催化剂可至少重复使用五次而活性无明显下降。

鉴于当前路由系统失效恢复未能有效解决备份拓扑存储代价、冗余恢复能力以及自治域利益保护等问题,该文在致瘫攻击易造成网络级联失效的背景下提出一种基于结构化备份子图的失效恢复方法 3R(Robust Route Recovery)。首先,设计拓扑关键点和重要邻接点生成算法,满足了备份子图基数小、增长率低的实际存储需求,且具备同一子图内多点冗余恢复特性;其次,为充分考量自治域利益诉求,设计基于流量权重的相邻链路排序算法,折中路由失效恢复与私有路由策略的双重需求;在此基础上,利用多次迭代生成各冗余恢复集合的备份子图。实验结果证实了方法的有效性。

本文介绍了基于边的数据结果离散对流扩散方程的方法,编制了适用于任意多边形单元网格的有限容积法计算程序,利用方腔自然对流、外掠后台阶和移动顶盖驱等算例考察了三角形网格与多边形网格在数值计算方面的性能差别。结果表明,采用三角形网格收敛较慢且不容易获得网格无关的解,而采用与三角形网格对偶的多边形网格则收敛较快且易获得网格无关的解。

采用离子液体辅助水热法制备锡酸锌,考察了溶液pH值、水热反应时间及水热反应温度对锡酸锌晶体结构、形貌及光催化性能的影响。采用X射线衍射(XRD)确定锡酸锌的晶体结构、结晶水平及相的纯净程度;透射电子显微镜(TEM)用来分析制得的锡酸锌的形貌;通过在紫外光照射下光催化降解亚甲基蓝进行锡酸锌的光催化性能研究,结果表明:溶液pH值为9、水热反应温度为220℃、水热反应时间为32h制得的锡酸锌对亚甲基蓝有最高的光催化降解活性。对锡酸锌降解亚甲基蓝的光催化机理探究表明:锡酸锌光催化活性的差异主要归因于缺陷,缺陷往往成为电子-空穴复合中心,导致光催化活性不高;羟基自由基是光催化反应的主要活性物种。
