密度大的

According to the principle of continuity of wave function, when different elements react with each other to form compound, the electronic densities of atoms at interface must be equal. Each atom should change the atomic radius to shift their electrical density, then this made huge micro-stress in atoms.

在单质元素原子形成化合物时，由于要满足量子力学的波函数连续原理，要求原子界面上的电子密度相等，各原子在化合时必须通过改变原子半径以达到相同的原子边界电子密度，从而在原子中产生了很大的微观内应力。

Aiming at the problems of over-fitting and generalization for neural networks, the locally most entropic colored Gaussian joint input-output probability density function estimate is studied, and a new method by means of Chebyshev inequality is proposed to self-revise respectively according to every cluster.

针对神经网络的过拟合和泛化能力差的问题，研究了样本数据的输入输出混合概率密度函数的局部最大熵密度估计，提出了运用Chebyshev不等式的样本参数按类分批自校正方法，以此估计拉伸样本集，得到新的随机扩充训练集。

Their electrochemical properties were investigated by charge-discharge of constant current, cyclic voltammogram, impedance spectrum and so on.

因其兼备传统电容器功率密度高和二次电池能量密度高的优点，以及可实现瞬间大电流放电，充电时间短、效率高，使用寿命长，无记忆效应以及基本无需维护等非常独特的性质而倍受关注，特别是在信息技术、电动汽车、航天航空和国防科技等方面有广阔的应用前景而受到广泛的研究[1-3]。

But the shell side flow was dominated by the laminar flow with increasing of the packing density.

在装填密度较小的时候，紊流倾向十分明显；当装填密度较大的时候，壳程的流动状况与层流相对比较接近。

Some of the contrast－polarity quadrochromatic in high density, to increase the level of the relatively small density differential is large, and more high low profile levels and low relief, such as surface relief of color film, production should contrive such images of light and shade of the main level of coordination, you can get a better copy reproduce the effect.

一些中高密度反差的原稿，中调层次较少，密度级差较大，而高低调层次较多且平缓，如逆光拍摄的彩色片，制作时应想办法使这类图像主体调的层次明暗协调，即可取得较好的复制再现效果。

Leaves structure of different provenances vary greatly in the thickness of keratoid layer, epidermal layer, palisade mesophyll, spongy mesophyll and the stomatal density. The CTR value is negatively related to the temperature of growing site and the SR value is positively related to it, which is an evidence for the plant to adapt to the environment.

西南桦不同种源叶片的结构在角质层、表皮层、栅栏组织、海绵组织厚度以及气孔密度等方面都发生了较大的变异，叶片的紧密度与种源地气温呈负相关，疏松度与气温呈正相关，这是植物对环境适应的表现。

On the other hand, real estate director of the Institute of Qinghua University Professor Liu Hongyu proposed, although the overall housing prices will not be any big change, but there will be changes in relative prices, such as the result of "atypical pneumonia", by the purchase of low-density residential Housing people in hot pursuit, a number of high-density project was to examine, bound to a certain extent, long-term impact of price movements of different products.

另一方面，房地产研究所所长清华大学教授刘轰渝提出，虽然整体房价将不会有任何大的变化，但将改变相对价格，如因&非典&通过购买低密度住宅的人穷追猛打，一些高密度的项目审查，必然会在一定程度上，长期影响价格变动的不同产品。

At the across sections of glacial sills and troughs, the density of striations increases gradualy from the side to the centre.

在冰坎和槽谷的横剖面上，从侧部向中部擦痕密度逐渐增加，槽谷的谷壁向谷底的转折处是擦痕密度由小转大的突变点，反映了磨蚀作用不断增强。

When the density of the eyedropper and the water and air inside it is greater than that of water, it sinks. When you stop squeezing the bottle, the pressure decreases and the eyedropper floats.

当滴管及管内的水和空气的密度比水的密度大时，滴管就会下沉；当你停止挤压汽水瓶，压力减小，滴管就会浮起。

In this study we use logbooks of purse-seine fishery during 1986 ~ 2002, AVHRR SST at a 4 km grid during 1986 ~ 2002 and SeaWiFS Chla at a 1 km grid during 1998 ~ 2002 as data availability permitted.

三类密度资源(CPUE1.0 t/网次、1.0≤CPUE2.0 t/网次、CPUE≥2.0 t/网次)出现面积的逐月变化各不相同，高密度资源出现面积最大的时间在3月及8 ~ 9月。

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。
