The main results are shown as follows:1.Screening freezing tolerant cultivars and lines of chrysanthemumTwenty seven lines of chrysanthemum grown outdoors were screened using \'injury rate\' and \'injury index\'.There were 7 cultivars and lines,which were relatively high tolerant to freezing treatment,i.e.,\'Jinbuhuan\',\'Xuetao\',\'Fuli\',\'Donglin 4\',\'Donglin 6\',\'Donglin 9\', and \'Donglin 13\'.There were 3 cultivars and lines,which were less tolerant,i.e.,\'Fenmeigui\', \'Donglin 1\',and \'Donglin 2\';The determination of electrolyte leakage,and contents of free proline,MDA,CAT,fructose,glucose and soluble sugars on 7 lines of chrysanthemums at different stages freezing showed that \'Xuetao\' and \'Donglin 4\' were more tolerant than others, and that especially \'Donglin 4\' was able to regulate its osmotic pathway to alleviate the \'injury degree\' caused by freezing conditions.2.Protein expression profile of chrysanthemum under low temperature stressTwo-dimensional liquid chromatography was applied to fractionate and analyze total protein taken from \'Donglin 4\' leaves grown at low temperature and at normal condition. Chromatography peaks of fraction were transformed to gel graph by ProteoVue software.

主要研究结果如下：1、露地菊抗冻品种和品系的筛选利用受伤率和伤害指数两项指标对27个露地菊品系进行耐低温筛选，筛选出'金不换\'、'雪涛\'、'富丽\'、'东林4号\'、'东林6号\'、'东林9号\'、'东林13号\'等7个耐低温品系，同时发现'粉玫瑰\'、'东林1号\'、'东林2号\'三个品系的耐低温能力最差；通过对不同自然低温处理时期，7个品系的电导率、丙二醛含量、脯氨酸含量、过氧化氢酶、果糖、葡萄糖和可溶性糖等指标的测定发现，'雪涛\'和'东林4号\'的耐低温能力要强于其它品系，尤其是'东林4号\'对低温的调节能力较强，在低温胁迫下，能够调节渗透途径减轻低温的伤害。2、低温胁迫下，露地菊蛋白质表达谱分析利用二维液相色谱技术，分离了'东林4号\'露地菊品系的低温处理和对照样品的总蛋白，通过ProteoVue软件分析发现：处理样品与对照相比共有蛋白差异点36个，其中显著增强表达的蛋白差异点有26个。

The sewage flows from pool to plant, passing through retention reservoir to adjust PH value, into removing ammonia with temperature increasing to 20℃,into UASB reactor with temperature increasingto 35℃ to remove off COD and ammonia under the function of anaerobia, then into SBR reactor to remove BOD under the function of aerobia. When the biochemical disposal is completed, the processed sewage will come into the UF system to remove adsorbed solid, organic matter, bacteria, and pathogens in waterand finally come into the RO system to remove off dissolvable salinity, colloid, organic matter, and microbe in water.

垃圾渗滤液经储存池进入污水处理厂，经调节池调整PH值，经1#加热器升温到20℃进入氨吹脱塔脱氨氮，再经2#加热器升温到35℃进人UASB生物反应器，在厌氧菌的作用下降解COD和脱氮，再进入SBR生物反应器，在好氧菌的作用下降解BOD，完成生化前处理后转入UF超滤中空纤维膜系统进行分离处理吸附固体、有机物、细菌、病原体等；最后经高压泵送入进口的RO返渗透中空纤维膜系统中，进行分离处理可溶解盐分、胶体、有机物、微生物等。

The watermelons, the citrullus lamtus or the stems and leaves thereof are taken as raw materials, and the extracting process comprises the following steps: firstly, the raw materials are washed clean and broken to separate the watermelon peel from the watermelon pulp for respectively extracting juice; the two juices are mixed, and micro-filtration and ultra-filtration are carried out to remove insoluble substances and macromolecular substances; and then reverse osmosis and nano-filtration are carried out to obtain the filtrate; the pH value of the filtrate is regulated and then a macroporous strong acid cation exchange resin column is added; and then ammonia water is taken as an eluant for isocratic elution; the eluent obtained is decompressed, distilled, deaminized, discolored, condensed and crystallized to obtain a white crystalline product of the natural L-citrulline extracted from the watermelons.

本发明方法以西瓜、打瓜或者其茎叶为原料，其过程为：首先将原料清洗干净，破碎后将西瓜皮西瓜瓤分开，分别进行榨汁；所得汁液合并，经过微滤和超滤除去不容物和大分子物质；然后再经反渗透和纳滤过滤；透过液调节pH值后通入大孔型强酸性阳离子交换树脂柱；然后以氨水做洗脱剂进行等度洗脱；将洗脱液减压蒸馏脱氨，脱色，浓缩结晶，得到西瓜提取天然L-瓜氨酸白色结晶产品。

Saccharobiose was used to maintain the osmotic concentration of the solution, The effect of osmotic pressure on livability, body volume and activity of the tadpoles were analyzed with ANOVA.
