使聚集

A model is suggested to explain the changes in the dispersion and electron state of Pt particles. Autoreduction of Pt〓 ions is found directly by means of CO-IR and TPR methods.

实验中发现了载Pt化合物中的NH〓配体在解离后吸附于β沸石酸性位上导致Pt〓的自还原作用，进而发生Pt粒子聚集使其分散度降低。

The two harmonic double drift buncher used by the IH structure bunches the beam to the bunches with the width of 360ps. Then the acceptance of the IH structure is increased to 240°.

该后加速器采用的二谐波双漂移聚束器，把束流聚集成宽度为360ps的束团，使加速腔的接受度提高到240°。

The results show that the conformation of copolymer molecules is totally different from that of carboxy methyl cellulose because of the introduction of the surface active macromonomers.

结果表明，共聚物在水溶液中的形态完全不同于羧甲基纤维素分子，亲水疏水链段的引入，使共聚物分子聚集形成了以疏水链段为核心的棍状胶束结构。

Dissolvion thrombus of Asp/Lze might involve that it could increase FDP level and depolymerize aggregated platelet.

另外，ASp／Lze能增加家兔血清中 FDP含量，是其溶栓的机制之一，使已聚集的血小板解聚，以溶解动脉血栓。

Being stimulated with LPS 1μg·ml-1, RAW 264.7 cells were observed under LASER confocal microscopy. Erythrine P65 subunit of NF-κB aggregated at nuceluses, which made Erythrine fluorescence of nuceluses much stronger than that of endochylema.

LPS 1μg·ml-1干预RAW264.7细胞后，激光共聚焦显微镜下观察结果显示，红染的NF-κB P65亚基聚集于细胞核，使胞核红色荧光明显强于胞浆。

Two reasons can be explained the improvements of catalytic activities after the addition of Ce. One is the increase of the thermal stability of Ni-B and Ni-P nanoamorphous alloys, which retards the nanocrystalline Ni to aggregate during the exothermal reaction of benzene hydrogenation. The other is to make their grain sizes smaller, thus it increases the number of activity center in unit mass.

说明加入Ce提高催化活性的主要作用有两方面，一是提高Ni-B和Ni-P纳米非晶态合金的热稳定性，抑制催化苯加氢反应时大量放热促使纳米晶Ni的聚集长大；二是使生成的Ni-B和Ni-P纳米非晶态合金颗粒更为细小，从而增加单位质量样品的活性中心数量。

The introduction of methoxyphenyl or fluorenyl endows significantly enhanced electron-accepting capability,and the LUMO energy level decreases from-3.50 eV of 1a to-...

同时，大尺寸芳香取代基的引入有效抑制了由于分子聚集而引起的荧光淬灭，使三亚吡嗪化合物的荧光量子效率从化合物1a的0.23提高到化合物1b的0.81和化合物1c的0.87。

The results indicated that the concentration of Cu in the soil is 220.16 mgkg^(-1) contrast to the CK 500.31 mgkg^(-1) significantly decrease when the concentration of EDTA in the soil is 2 mmolkg^(-1) that explains EDTA treatment significantly decreased soluble Cu content in soil because of translating into Cu of water distill floating on the surface of soil and most accumulating around root. Contemporary, application of EDTA to the soil significantly enhanced mobilization of Cu in soil and increased Cu uptake in shoot of Leersia hexandra Swartz., the highest concentration in the leaves 336.54 mgkg^(-1) is 4 times higher compared with the ck 80.34 mgkg^(-1). However, citric acid, oxalic acid and malic acid inhibited mobilization of Cu and less significantly affected shoot Cu accumulation.

结果表明，当向土壤中施加质量摩尔浓度为2mmolkg^(-1)的EDTA时，土壤中Cu质量分数为220.16mgkg^(-1)与空白土壤中500.31mgkg^(-1)相比明显减少，说明EDTA可以极显著的降低土壤中的铜质量分数，使其转化成水提取态的Cu浮于土壤表面，并大部分聚集在根部周围，同时向土壤中施加EDTA不但促进了对Cu的活化而且显著提高了李氏禾对Cu的吸收，叶中最高质量分数达到336.54mgkg^(-1)是对照中80.34mgkg^(-1)的四倍；而柠檬酸、草酸和酒石酸则抑制了Cu的活化，但对李氏禾地上部分的Cu质量分数影响不大。

DSC and WAXD studies showed that the block copolymers were meltable, and due mainly to the flexible nylon6 segments.

采用DSC热分析的方法，结合WAXD，研究发现，所合成的嵌段共聚物具有可熔融的性质，主要的转变来自柔性的尼龙链段；通过对聚合物空间立体结构的改造，分子链中间位结构的引入以及两嵌段组分分子间和分子内的相互作用强烈影响嵌段共聚物的结晶行为，使结晶更不完善，晶体结构更为疏松，自聚集倾向在很大程度上得到抑制。

And Samuel said, Gather all Israel to Mizpah, and I will pray to Jehovah for you.

7：5 撒母耳说，要使以色列众人聚集在米斯巴，我好为你们祷告耶和华。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
