摘要：[目的]优化复合酶法提取南瓜多糖的工艺条件,研究南瓜多糖的抗氧化性。[方法]采用单因素试验设计研究了不同提取时间、温度、料液比、pH对南瓜多糖提取率的影响,并通过正交试验确定了提取南瓜多糖的最佳的复合酶配比和最佳提取条件。采用水杨酸法检测南瓜多糖对羟基自由基(.OH)和改进的邻苯酚自氧化法检测其对超氧阴离子自由基(O2-)的清除效果。[结果]当纤维素酶的浓度为1.0%、果胶酶为1.5%、木瓜蛋白酶为1.0%时,以及温度为40℃、pH=4.6、料液比为1∶30、提取时间为30min的条件下南瓜多糖的提取率最高;南瓜多糖对.OH具有较好的清除效果,对O2-有部分清除作用。[结论]该研究为南瓜多糖的研究及应用提供了基础资料。

摘要：United States Botanic Garden(USBG) was taken for example to systematically demonstrate the role of formal composition in garden landscape *** cases were used to analyze formal composition of plant landscapes in *** plant landscapes lay the foundation of all other forms,concentrated and centripetal effects of which can form comparisons according to size of *** is the trace of moving points,and linear plant landscapes indicate those formed by using thick,thin,long,short,square,round,curved and straight "lines".And surface plant landscapes are to form contrastive images or scenic areas by using plant ***,concrete cases were given to analyze flowerpot selection and combination for creating point,linear and surface potted plant landscapes,and to provide detailed reference for the plant design of modern Chinese gardens.

摘要：Traditional architectural construction style had rich connotation for application and transformation in contemporary architectural space *** buildings in the eastern areas of Zhejiang Province as the research subjects,the paper explored forms of application and transformation and specific design techniques from microcosmic point.

摘要：1苏杭园林景观特征苏州古典园林是江南私家园林最突出的代表,多为自然山水园或写意山水园。其特点如下:山水是园林的骨架,植物只是毛发而已;景观诗意化,即园中造景及赏景的标准常重意境,不求实际比例,着力画意;

摘要：滨州安康居住区位于滨州市东北角,是政府安居工程,属经济适用房,分为安康南区和安康北区两部分。笔者主要对安康南区湖南和湖东的绿地进行种植设计。1绿化设计原则1.1注重节约性,强调经济性主要体现在:①苗木大多为乡土树种,移栽成活率高;②苗木以中小规格为主,大多数直径在10cm以下;③草坪及地被符合既耐盐碱,又耐旱、耐寒的要求。
