相当微小的

This surface works a bit like a giant radio telescope dish in reverse: Rather than focusing parallel astronomical light rays to a point, it collects the scattered plasmons emerging from a tiny sample--positioned strategically near the mirror--and redirects them into a plasmon "beam" in the metallic plane.

这个表面的工作原理相当于一个倒置的巨型射电望远镜的盘面，不同于天文望远镜把平行的天体光线会聚到一点，这一设计起到的作用是收集从一个位置恰好位于像点的微小样品散射出来的等离激元，并把他们重定向成金属平面上的一个等离激元束。

Especially, the difference of the nearest-neighbor hopping integral is due to the effect of the curvature of the carbon nanotubes. So, in fact there is a very narrow energy gap near the Fermi energy of unsquashed metallic zigzag carbon nanotubes, and, a slighter deformation is required to open a considerable energy gap in metallic zigzag carbon nanotubes than that in armchair nanotubes.

特别是，最近邻格点之间的跃迁积分的变化与碳纳米管的曲率紧密相关，因此实际上，理想金属型 zigzag 碳纳米管本身具有微小能隙，而施加比 armchair 碳纳米管小的多的压缩量，就可以使金属型 zigzag 碳纳米管在费米能处打开相当的能隙。

The structures were studied by IR and NMR. The absorption frequencies of the carbonyl group markedly depended on the coordination no. of the tin atom. The chem. shifts of 119Sn and 13C and the 1J(119Sn-13Sn) coupling constants of the compounds were determine Small structural changes around the tin atom were reflected in the 119Sn chem. shifts. For tributyltin arylcarboxylates, a relationship between 119Sn chem. shifts and Hammett constants of the para-substituents was found. The biol. activities of same compounds have been studied. They may be used as fungicides for fruit.

通过对它们的红外光谱、核磁共振谱(^1^3C， ^1^1^9Sn)的研究，表明羰基红外吸收频率与锡原子的配位数有密切关系，同样分子上的微小变化明显地表现在δ119Sn上，对位取代基苯甲酸酯的δ119Sn与苯环上取代基的Hammett常数之间存在良好的线性关系：δ119Sn=19.11σ+110.612 n=7，γ=0.9955着重研究了部分化合物在经济作物上的抗病原菌能力，结果表明，这是一类具有广谱性的有机锡化合物，抗菌活性优于对比药剂朴海因，接近或相当于多菌灵，它们同时具有较强的除草活性。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
