没有降低的

Although not technically unrealizable FTTH difficult, but to make FTTH towards success is worth paying attention to the following areas : research and development efforts should focus on the characteristics of new devices and meet FTTH core chip, lowering the cost of optoelectronic devices and passive components; Development of low-cost, easy to install indoor fiber, cable and connector alignment of the construction equipment and tools; Development of high density, easy-to-use fiber patch panel; focus on the development of remote monitoring and management technologies and systems.

FTTH虽然没有技术上不可实现的难点，但要使FTTH走向成功，以下方面值得重视并应集中力量攻关：开发适应FTTH特点的新型器件和核心控制芯片，降低光电器件和无源器件的成本；开发低成本、易安装的室内光纤、光缆和连接器及相配合的施工仪器工具；开发高密度、易操作的光纤配线架；开发集中的远程监视和管理技术及系统等。

The results show that the ζ potential of PYM-PO4SiNP decreased obviously, and the release rate of PYM from the PYM-PO4SiNP accelerated with increase of added THPMP. However, the quantum of THPMP had no impact on the size of PYM-PO4SiNP.

结果表明，随着磷酸化修饰试剂量的增加，制备的PYM-PO4SiNP的电位逐渐降低，其包载的PYM的释放速率逐渐加快，但对颗粒的粒径没有明显影响。

Under different stresses, we tested the expression of citrate synthase gene in rapeseed leaf by using semi-quantitative PCR. The expression of citrate synthase gene had no obvious change in stresses of salt, dark, high illumination, while was increased at different time in treatments of water logging, drought, IAA, and 6-BA. Interestingly the effect of ABA was contrary to that of IAA. In the treatment of sclerotium blight, the expression of citrate synthase gene was depressed. There was a saddle curve of citrate synthase gene expression in the treatment of gibberellin.

对油菜幼苗进行植物生长调节物质、高温和低温、强光照和弱光照、盐、菌核病、干旱和水渍等处理，采用半定量PCR法对油菜叶片柠檬酸合酶基因的表达模式进行检测，发现在盐胁迫、暗光和强光的处理下，柠檬酸合酶基因的表达基本没有变化；在水渍、干旱、IAA和6-BA胁迫下，其表达有所升高，但出现峰值的时间不同，ABA对表达模式的影响与IAA相反，感染菌核病后其表达降低；对GA3的应答呈鞍型。

Lack of significant growth in the world average yield in upland cotton since 1991 reinforces the impression that the cotton industry has entered into a long梩erm period of slow growth in production. Breeding contribution to the yield growth has sharply decreased, and the result of cotton cultivar performance of regional test displayed that the potentials for the growth of yield in new developed cultivars was delimited, which implies that we must pay more attention to the studies on the diversity of cotton cultivers and genetic mechanism for yield traits.

自90年代初以来，英国及世界的棉花平均产量没有明显得到提高而育种方面对产量的贡献已大大降低；我国的棉花品种区域试验结果也表明，常规品种的增产幅度较低，需要深入研究棉花品种的遗传多样性和产量性状的遗传规律。

D. of the catalyst increased, i. e. the acid volume of the catalyst increased, the conversion for isobutene and the selectivity for trimer increased also, while the selectivity for dimer decreased, and the selectivity for tetramer was almost unchanged.

D。增加时，即催化剂的酸量增加时，异丁烯的转化率和三聚物的选择性也增加，但二聚物的选择性降低，四聚物的选择性则几乎没有变化。

The first part deals with pore seating, mechanical strength and alkaline reduction; the second with fibre impregnation includin9 a short description of the compounds used and the agein9 of mortars, with or without admixtures, which are reinforced with sisal fibres impregnated or unimpregnated under different conditions.

第一部分涉及孔隙密封，机械强度和降低碱性；第二部分纤维浸渍和纤维注入 includin 9 的化合物用了和砂浆湖混合的 agein 9，由于没有混合，被浸渍的剑麻纤维加强和不浸渍的存在不同的情况。

During the magmas ascendedand intruded, the high-energy, quick ascending primary mantle magmas with xenolith andhigh-pressure megacrysts didn't react with the crustal matter, which formed products, such ascone sheets.

在岩浆上升侵位的过程中，能量高的快速上升的含有岩石包体和高压巨晶的幔源原生岩浆没有与地壳物质发生作用，其形成的产物如锥状岩席；在此之后，岩浆能量、上升速度的降低促使原生岩浆与围岩发生轻微的同化混染作用，其产物如火山熔岩和火山颈。

Methods: DECB was dealed with heat , acid , alkali , roasting , organic solvent extracting , microorganism zymolysis , then the method of microrespiromete was used to detect/measure the respiratory activity respectively.

目的：研究小牛血清去蛋白提取物（deproteinated extract of calf blood，DECB）中生物活性物质的物理化学性质；方法：分别将小牛血清去蛋白提取物进行加热、加酸、加碱、烘烤、有机溶剂萃取、接种微生物发酵等方法处理，然后分别用微量呼吸检压法检测呼吸活性，结果：采用加热、加碱、加酸，接种微生物发酵的方法进行处理，DECB刺激呼吸活性的能力没有明显改变，而采用烘烤的方法处理，结果DECB的活性完全消失；用有机溶剂萃取DECB，可明显降低DECB刺激呼吸活性的能力，而有机相中含有了刺激呼吸活性物质。

The Orion was a ship that had been ailing for a long time; in the course of its previous cruises thick layers of barnacles had collected on its keel to such a degree as to deprive it of half its speed; it had gone into the dry dock the year before this, in order to have the barnacles scraped off, then it had put to sea again; but this cleaning had affected the bolts of the keel: in the neighborhood of the Balearic Isles the sides had been strained and had opened; and, as the plating in those days was not of sheet iron, the vessel had sprung a leak.

俄里翁号是一条早已有了毛病的船。在它已往的历次航行中，船底上已结聚了层层的介壳，以致它航行的速度降低了一半，去年又曾把它拖出水面，剔除介壳，随后又下海了。但是那次的剔除工作损伤了船底的螺栓。它走到巴利阿里群岛时，船身不得劲，开了裂，由于当时的舱座还没有用铁皮铺底，那条船便进了些水。

TEM shows that drying by direct heating might result in hard aggregation of the tourmaline powder, while hard aggregation might be avoided by azeotropic distillation. Raman spectroscopy reveals that there are O_H and C_H on the surfaces of the tourmaline powder obtained by azeotropic distillation, which indicates that butoxy is chemically adsorbed on the surfaces of tourmaline particles, but not adsorbed on those formed by direct drying. X_ray powder diffraction shows that the intensity of diffraction peaks decreases after grinding. There is no damage to the tourmaline crystal lattice in the process of direct heating, azeotropic distillation, or ultrafine grinding.

透射电镜分析结果表明，直接加热脱去水或正丁醇会使电气石超细颗粒发生硬团聚，而共沸蒸馏法则可有效防止硬团聚的产生；拉曼光谱结果表明，共沸蒸馏法制备的电气石粉末表面存在O—H和C—H键，说明正丁醇在颗粒表面为化学吸附，而直接干燥法得到的电气石粉末表面则没有；X射线粉晶衍射结果表明，研磨过程降低了粉末衍射峰的强度，但直接加热干燥和共沸蒸馏干燥均未破坏电气石的晶格结构。
