Influence of Plant Growth Regulator on the Germination Percentage and Seedling Growth of Lolium perenne L .;3. Detection and Quantification of the Endophyte in Lolium perenne L .

由于碱木素中胶体分子有带电的核和溶剂化外壳,构成亲水基因,从而具有一定的表面活性,掺入混凝土中能起一定的减水效应。

Because of this property, water is preferentially adsorbed by these surfaces, and large organic compounds cannot compete with strongly held water for adsorption sites on the clay surfaces. Thus, Na-clays are ine_ective sorbents for small organic molecules. However, it is possible to modify the surface properties of clays greatly by neutralizing the anionic framework of layer silicates by using positively charged organic species such as alkylammonim ions. In the modi_ed form (HDTMA-bentonite), the clay surface may become organophilic and interact strongly with organic compounds. Textile dyes represent a relatively large group of organic chemicals. In an HDTMA-bentonite-dye system it is possible that adsorption may be enhanced by the hydrophobic interaction between the adsorbed dye molecule and HDTMA-bentonite.

O组给予亲水的性质到矿物表面,因为这水是吸附在这些表面,和大的有机化合物不能比有坚强的为了吸附位置在泥土表面,因而,Na—泥土是ine_ective吸附剂为了小的分子,希,它是可能的到更改的表面属性,泥土非常在抵销anionic层硅酸盐在用的结构 Positively负荷的物种例如alkylammonim离子,在mod i_ed形状,泥土表面可能变成organophilic和互相作用坚强地有机化合物,织物染料表现相关的大的组化学的,在HDTMA—斑脱土—染料系统它是可能的那吸附可能是提高在交互作用在中间吸附染料分子和HDTMA—斑脱土,interlamellarHDTMA的间隔—斑脱土是获得在substracting泥土层从的厚度实验上坚决的基础的间隔(d001)。

SiO 2/TiO 2 superhydrophilic coating on glazed tile substrate was prepared by solgel method,the surface chemical composition, contact angle of water and photographs of surface of the coating were studied by use of XPS,photomicroscopy and SEM.

用溶胶 -凝胶方法在釉面砖上制备了SiO2 /TiO2 超亲水涂层,用XPS、光学显微镜和SEM研究了涂层的表面化学组成、水润湿角和表面形貌。

In part 2, with the idea of being close to water, it seeks a cut-in from the correlation of water and architecture.

第二部分从人类与建筑的亲水观念中寻求水与建筑相互关联的切入点。

The PS-b-PNIPAM-b-PDMA and PS-b-PDMA-b- PNIPAM triblock copolymers can self-assemble into PS-core micelles, which possess a three layer \'onion-like\' structure, with PDMA and PNIPAM blocks forming the inner layers or outer coronas. Using above measurements, we can concluded that PS-b-PNIPAM-b-PDMA triblock copolymer micelles have the double phase transition behavior, while PS-b-PDMA-b-PNIPAM have only one phase transition behavior.2. We synthesized poly(ethylene glycol-b-methacrylic acid)diblock copolymers with three different polymerization degree of PMAA blocks.

但是对于PS-b-PDMA-b-PNIPAM胶束,由于中间亲水嵌段的作用,使PNIPAM的相转变温度提高,且PDMA由于靠近PS内核以及随着外壳PNIPAM的水溶性变差其相转变点降低,因此我们只能看到一个转变过程。2、通过原子转移自由基聚合,我们合成了三种不同PtBMA长度的PEG-b-PtBMA二嵌段聚合物,将叔丁基水解后得到了三种PEG-b-PMAA二嵌段聚合物。

The PVA could help CNTs weltering the aquatic phase and enhance the stability of their dispersion. The PVA had bifunctional bridges, with hydrophilic groups jointed with the Fe2O3 film, and hydrophobic chains adhered to the surface of the carbon nanotubes, so the Fe2O3 were supported on the surface of the carbon nanotubes through the surfactant.

聚乙烯醇均匀吸附在碳纳米管表面,增强碳纳米管在水溶液中的分散,其疏水基团与碳纳米管以范德华力结合,其亲水基团与Fe2O3·nH2O结合,对碳纳米管有效负载Fe2O3起到了桥梁作用。

Volume rate of only 1.0 of a purely modern waterfront building, hand in hand hydrophilic sightseeing elevator, walking the design and much independent, underground garage directly modules ,117-185 ㎡ house type of planning, and more outdoor space with three elegant garden home Housing, including the private courtyard at the end of row house design town, over 270 degrees independent of the luxury landscape Terrace Top jump to meet the life style of a variety of people to imagine.

The increase in WHC of resistant starch having guar gum over resistant starches with guar gum and different chemical agents could be ascribed to non interference in the chemical configuration and composition especially in greater number of hydrophilic sites on the gum that allows the occlusion of water within the structure.

单独含有瓜尔豆胶的抗性淀粉其WHC比含有瓜尔豆胶和其他化学试剂的抗性淀粉高是因为在胶上一些亲水基团上无化学构象,这导致了水在结构中的封闭。
