查询词典 size

Nanomaterials have many new characterizes which different from the normal materials for their small size, big surface area ratio and quanta dimension domino effect, for examples, the metal with good conductor will be turned into nonmetal when the size is reduced tonanometer levels; the resistance of originally nonconductor will be descended greatly when its size is reduced several nanometers or so, and loss the nonconductor property; the general solid is steady under certain conditions, while under nanometer conditions, the capabilities will be effected greatly by the granule sizes, the newness characteristics made nanomaterials have great appliance foreground on catalyze, optics, and industry produce and so on, therefore the nanomaterials have been the hotspot for materials science, chemistry science and so on.

纳米材料由于尺寸小、比表面积大和量子尺寸效应使它具有不同于常规固体材料的新的特征，如原来是良导体的金属，当尺寸减小到纳米量级时就变成非金属型；原来是绝缘体的物质，当尺寸减小到几纳米或几十纳米时电阻大大下降，失去了绝缘体特性；常规固体在一定条件下物理性能是稳定的，在纳米状态下，颗粒尺寸对性能产生强烈的影响等等，这些新奇的特点使得纳米材料在催化、光学、工业生产等各个方面都有着广阔的应用前景，因此，纳米材料目前已经成为材料科学、物理学及化学等学科的前沿热点。1990年7月在美国巴尔基摩召开了国际第一届纳米科学技术会议，正式把纳米材料科学作为材料科学的一个新的分支公布于世。

It was found greater expression of NRP2-1 and NRP2-2 in pituitary, ovary, uterus and oviduct of ruttish Erhualian than corresponding tissues of ruttish Duroc, which suggested enhancing expression of NRP2 was favorable to increasing litter size. But the difference of NRP2 expression was not significant between two breeds, which suggested the key phase that NRP2 affected litter size was not oestrum probably, or NRP2 could enlarge cell signals and finally affect litter size ascribe that it was the receptor of nerve axon guidance factors.

NRP2-1和NRP2-2在发情期二花脸卵巢、子宫、输卵管中的表达量均大于杜洛克相应组织的表达量，推测NRP2表达水平高可能有利于提高产仔数，但两品种间表达差异不明显，推测NRP2影响产仔数的关键阶段可能不是猪的发情期；另外，NRP2 是神经轴突介导因子的受体，这些神经轴突转导的信号往往有级联放大的功能，虽然NRP2-1和NRP2-2在二花脸和杜洛克卵巢、子宫、输卵管中的表达差异不大，但二花脸有可能通过神经系统转导信号的级联放大最终引起一些效应激素或蛋白的急剧增加，从而提高排卵率或产仔数。

Cluster analysis and two-way contingency table analysis were used to study the ontogenetic variations in the feeding habits of plaice, and the results showed that the feeding activity of plaice did not vary significantly among 7 size classes within the size between 51 mm and 370 mm, but ontogenetic variations were found in the diet composition. In the size class 200 mm, plaice mainly fed on Decapoda and fishes.

通过聚类分析和列联表检验等方法对高眼鲽摄食随体长的变化进行研究，结果表明：体长在51~370mm范围内的高眼鲽的摄食强度没有显著的体长变化，但不同体长组摄食的食物种类有一定差异。200mmm的则主要摄食底层虾类和鱼类，磷虾类所占比例减小。

Plaques of these virus strains were obviously different in size and shape. The plaques of A/Vietnam/1194/2004 (H5N1) were mainly large in size and round in shape, except for a few smaller plaques appearing punctiform in shape. While A/Beijing/01/03(H5N1) were dominated by plaques of moderate size, also mixed with a few punctiform plaques.
