查询词典 two-dimensional distribution

Two kinds of cross-linked polyacrylate latices with relatively narrow distribution of particle diameters, which are abbreviated to P and P/P, were synthesized by seeded emulsion co-polymerization, respectively. Butyl acrylate and 2-ethylhexy! acrylate were used as comonomers of ACR core, styrene and methyl methacrylate were employed as comonomers of ACR shell, and 1,4-butanediol diacrylate was used as cross-linking agent.

随着代次增加，有机质和交换性Ca下降明显；土壤的CEC和交换性酸分别下降了8.8—16.1%和6.8—18.5%，因此，其养分总量亦逐代降低，其中有机质下降幅度最大；土壤酶的活性具有明显的垂直分布特征，相关分析表明，过氧化氢酶活性与土壤OM、全N、有效P、K和交换性Mg有极显著的正相关，而与盐基总量、盐基饱和度呈明显的负相关。多酚氧化酶活性与OM呈显著负相关，与全N、交换性Ca有显著相关。脲酶活性则有随连栽代次增加而有下降趋势，前两种酶在代次之间变化不明显，可能与频繁的土壤干扰有关。

The clinical characters of oligodontia concluded from this study are following:(1) There is significant difference that more teeth absent and more existent teeth anomalies in patients of oligodontia/S group than in patients of oligodontia/I group, and the peg-shaped upper lateral incisor is the most frequently affected teeth with shape anomaly.(2) Both of the two groups have no significant differences in number of teeth missing between maxilla and mandible as well as that between left and right side.(3) The distribution of teeth missing is bilateral symmetry in both groups, but the frequency of teeth lost are different: excluding the third molar, in oligodontia/I group, the lower second premolar is the most frequently congenitally missing tooth followed by the upper lateral incisor, while in oligodontia/S group, the most frequently missing teeth are mandibular canine and maxillary lateral incisor. Nevertheless, the first molars are the most stable teeth in both groups.(4) In oligodonita/I group, the mean mesiodistal dimensions of all type of existent teeth are significantly smaller than normal value. It is implied that oligodontia is not an isolated phenomenon, but is related to a complex of other dental changes.

对于口腔多个恒牙先天缺失的临床特点有以下初步结论：(1)综合征型先天缺牙患者较单纯型先天缺牙患者恒牙缺失数目更多，平均分别为23.9个和14.9个，且现存牙齿有更多的形态异常，分别为7／10例（70％）和6／22例（27.3％），其中最常见的是上颌侧切牙畸形；(2)两种类型的多个恒牙先天缺失患者的缺牙数目在上下颌及左右侧之间均无差别；(3)两种类型的多个恒牙先天缺失患者在缺失牙位上均呈对称分布，但在具体牙位上有所差异：不计第三磨牙，单纯型先天缺牙最常缺失的牙位是下颌第二双尖牙、其次为上颌侧切牙；而综合征型先天缺牙最常缺失的牙位是下颌尖牙和上颌侧切牙；无论何种情况，第一磨牙均为牙列中最稳定的牙齿；(4)在单纯型先天缺牙患者中，现存恒牙的牙冠宽度较国人正常值偏小，差异显著，提示牙齿形态与多个牙先天缺失有一定相关性。

The creative point of this dissertation consists firstly in that monochromatic stimuli instead of combined spectral power distribution were used as visual object, and spectral luminous efficacy curves were drawn from the performance-based method; Comparison between performance-based method and brightness-matching method was then done and therefore connection between these two methods was developed; One more creative point is that the analysis based on the theory of neurophysiology and psychophysics leads to the conclusion that contribution of the colour channel during visual information processing is reflected from performance-based method, which should be considered when CIE develops the new mesopic photometry system.

论文的新颖之处在于实验中使用了单色光谱代替复合谱或物体色作为视觉目标，在分析中间视觉状态下视觉功能的光谱响应特性的基础上反推了人眼的光谱光视效率函数；论文更进一步验证了基于视觉功能法和传统的视亮度匹配法之间的联系，在两种方法之间构造了一座桥梁，为基于视觉功能法的使用初步建立了理论依据；同时论文创新地采用心理物理学的方法进行实验和结合物理学和视神经生理学的知识对实验结果进行分析，从而从视觉信息处理的神经机制层面证明了基于视觉功能法获得的结果包含了视觉颜色通道效应，并对CIE在建立新的中间视觉光度学系统时要充分考虑这一视觉颜色通道的影响提出了建议。

结合对鹿属古生物学资料和现代各个种的地理分布的分析，作者认为，鹿属染色体进化的主要机制是罗伯逊断裂，即一条中部着丝点染色体在着丝点部位断裂成为两条端着丝点染色体。

For example: peripherin-layer is made of nuphtheroquinon-xylenediol azide-anti-alcohol (microspectroscopic catalysical sensitivity range of up to 320 ~ 460nm), PS print, when you choose to use iodine gallium light, exposure time, simply by 20s with high pressure mercury lamp above the 30s, because although the two lamps and the spectral 300 ~ 460nm scope, but sulfonylated spetroscopy gallium light emission from 400 nm wavelength in close to the section of the distribution of light energy and light energy than much of high pressure mercury lamp, uniform is also much larger, and with this kind of formulation-peripherin-catalysical spetroscopy, emiting anastomasis sensitivity more productive.

感平层是用邻二叠氮醌型感平剂（平谱不分平感量边界为320～460nm）的PS版，晒版时若采取碘镓灯，曝平工夫只需20s把握，用矮压水银灯则给30s以上，这是因为：虽然两栽灯具的平谱成不分都在300～460nm边界边，但磺镓灯不收射的平谱洋挨近400nm波不幼段的平能量的不分布及平能量比矮压水银灯平均得众也不小得众，并且与这栽感平剂型的平谱不分平感量更为吻不分，不收平效果也更矮的原由。
