Numerical calculation shows that the mean-square radius of gyration decreases with increasing of the core functionality and decreases sharply When f is small.

计算结果表明，均方回转半径随着星核官能度的增加而下降，特别是官能度比较小的时候，下降幅度比较大。

From ultrastructure of RBC which co-cultured with HAP|,HAP4,HAP5,we have observed that HAPi and HAP4 can induce RBC membrane to deform and decrease stability of RBC membrane, so the particles can enter intramembrane, as a result, intracellular hydroxyapatite nanoparticles may heighten the concentration of Ca2+ and effect structure of membrane protein, membrane lipid and hemoglobin, subsequently,the deformability of RBC decreased all the better and leaded to erythrocyte aggregation. However,HAP.s uniformly dispersed around cell and didn't adhere to it,also, cytomorphosis cannot be found.

观察HAP_1，HAP_4，HAP_5与细胞作用后红细胞的超微结构中，HAP_1与HAP_4引起红细胞膜变形和膜稳定性下降，粒子进入胞内，进入胞内的HAP纳米粒子可能升高胞内Ca~(2+)浓度，从而影响膜蛋白、膜脂、血红蛋白的结构，使红细胞变形性进一步下降，最终导致聚集的发生。

In this study we report on both Global and Hedonic WB assessed in a 2008 telephone survey of 340,847 people in the United States.

诸如压力和愤怒等消极情绪在人们经过20多岁的早期之后下降，担忧在50岁之后下降。

After therapy the hemogram and main liver functions changed to normal or decreased significantly; the activities of SOD (except 2 patients) and Cat increased obviously (P.01), and the contents of H2O2 and MDA dropped markedly.

治疗后白细胞和主要肝功能指标转为正常或明显下降；病人血液中SOD（除2例下降外）和Cat活性均明显升高(P.01)。H2O2和MDA含量则显著降低(P.01)。

Methods Before treatment, the first hemospasia and BPRS evaluation were taken, and indices of blood rheology measured using XNs Electron Auto Whole Blood Viscosity Red Cell Electrophoresis Apparatus (researched and produced by Shanghai Medical University) in the 32 schizophrenics.

经氯丙嗪治疗2周后，重复上述实验及第2次BPRS评定。统计学处理采用t检验。结果32例精神分裂症病人治疗前血液流变学指标较正常人有明显异常，经氯丙嗪治疗后，全血高切变、全血低切变、红血球压积和红血球电泳时间有显著下降，同时BPRS评分也下降，其差异均有显著意义（P＜0.05）。

In iron-deficient cells, photosynthetic pigments content decreased, efficiency of photosynthesis was low, With the increase of the concentration of the iron-chelator 2, 2'-Dipyridyl in media, Fv/Fm decreased, indicating photoinhibition increased, the results were consistent with previous research; Heterocyst induction had one delayed time dependent on the status of iron-deficiency, More severe of the iron-deficiency condition, more late of the heterocyst induction, It is possible that certain iron-related genes may directly regulate heterocyst development; under different iron limitation conditions, Protein pattern were different, more serious of the iron-deficiency conditions, less bands of the protein pattern, We could not find the iron-deficiency induced protein; In general the toxic effects of ROS were potentiated by excess iron, But our results revealed that even under iron-deficiency conditions, Oxidative damage existed.

铁限制的细胞光合色素含量下降，光合作用能力下降，随着铁螯合剂2，2'-dipyridyl浓度的增加，叶绿素荧光F〓／F〓逐渐降低，显示光抑制变强。与前人的研究结果相似；依赖铁缺失状态，异形胞诱导有一段推迟的时间，铁缺失越严重，诱导越迟，推断某些铁相关的基因会直接调节异形胞发育；在不同铁营养条件下，蛋白质图谱的变化趋势很明显，缺铁越严重，则蛋白质谱带数愈少，但本文未能找到特异诱导蛋白；一般认为铁过量情况下ROS产生加强，本文结果显示即便在铁缺失条件下，也有氧化胁迫伤害，而且缺铁越严重，活性氧伤害越大。

Gas holdup decreases apparently with the increasing of temperature, which becomes less at higher solid concentration.

气含率随温度的升高而明显下降，其下降的幅度也随固含率增加而减小。

As for plant engineering, 2006 closed with a estimated global production of around 250 thousand tonnes, two thirds of which was traded, with the Italians still first despite having lost five points of the market share, which has dropped from 42 to 37 percent, with shipments for over 600 thousand hundredweight and a turnover of 500 million euro, with 245 million in consumables (abrasives, blades, diamond-tipped tools, adhesives and similar products), on the increase overall.

到2006底，全球设备工程的生产量估计达到25万吨。其中三分之二用于贸易。尽管其市场份额下降了5个百分点，从42%下降为 37%，意大利的机械设备市场仍然位居全球第一。机械运输超过60万英担，营业额多达5亿欧元。其中2.45亿欧元来自消费品（如研磨材料、刀片、金刚石绳锯、胶粘剂及其相关产品。

Water retention value of the bleached wheat pulp decreased The fiber of refined pulp have a more amorphous area, refined pulp contains more fines, more hydrogenous fibrils, colloidal cellulosic material can be produced on the surface of fibers.

纤维素酶酶解的是一些比表面积较大，亲水性较强的胶体性纤维，这些物质的去除也使纸浆的保水值下降。同时，酶攻击了纤维的薄弱处，使纸浆的聚合度稍有下降。

In the action of Dimilin, the diversity levels of Lepidoptera and Orthoptera insect of the treatment plot had a certain degree decline, and the diversity degrees of Hymenoptera insect and spider had a large increase, thus insect community in the treatment stand tended to be relatively stable.

在时间过程中，施药区鳞翅目和直翅目昆虫的多样性水平有一定程度的下降，但下降程度不如对照区大，膜翅目和蜘蛛的多样性水平则有较大程度的上升，因此林内昆虫群落趋于相对稳定。

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％。
