卤素

First we will use sea water for breeding, then we will develop and utilize the moderate brine and saturated brine drained after breeding to extract bromine for raw salt solarization.

项目拟在盐碱滩上引入海水，先用海水进行养殖，然后对养殖后排出的中度卤水、饱和卤水进行开发利用，提取溴素，晒制原盐，再将晒盐后排出的苦卤进行回收加工氯化镁、氢氧化镁等化工产品，最终实现海水"零排放"，达到最大限度利用资源，降低生产成本，实现可持续发展。

Results Six compounds were isolated from the ethanol extracts of Acrostichum aureurm,and their structures were elucidated as ponasterone A(1),pterosterone(2),kaempferol(3),quercetin(4),4-(3,4-dihydroxyphenyl)-2-butanone(5),and daucosterol(6),respectively.

结果从卤蕨乙醇提取物中分离得到6个化合物，分别鉴定为ponasterone A(1)、pterosterone(2)、山奈酚(3)、槲皮素(4)、4-(3，4-二羟基苯基)-2-丁酮(5)、胡萝卜苷(6)。结论6个化合物均为首次从该植物中分离得到。

ABSTRACT To study the antibacterial constituents from the fermentation broth of endophytic fungus Penicillium sp. 0935030 from mangrove plant Acrostichum aureurm. The separation procedure was guided by antibacterial bioassay. Seven compounds were isolated and purified by column chromatography, and their structures were identified as cyclo (1), cyclo (2), 1(2Furanyl)1,2ethanediol (3),(3β,4β,22β)olean12ene3,22,23triol (4), mannitol (5), uridine (6), and liquiritigenin (7) by physicochemical and spectral data.

为研究红树林植物卤蕨内生真菌Penicillium sp.0935030发酵物中的抗菌活性成分，采用活性追踪的方法，用多种色谱技术对化合物进行分离纯化，通过理化性质和光谱数据鉴定出7个化合物，分别为：环(1)，环(2)，1呋喃基1，2乙二醇(3)，(3β，4β，22β)12烯3，22，23三羟基齐墩果烷(4)，甘露醇(5)，尿苷(6)和甘草素(7)。

These floodlights are designed for tungsten halogen lamps.

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
