冠

The change on the spectra of the colored-form is alsohigher than that of the corresponding fulgide.

当冠醚与金属离子的匹配情况较好时，吸收光谱的蓝移更为显著，表现出冠醚所特有的选择性。

The electron donorability of the electron donor part of the fulgide decreases when cationcomplexes with crown ether, and the intromolecular charge transfereffect reduces.

金属离子较大的电荷密度以及金属离子与冠醚较好的匹配使冠醚俘精酸酐分子内的电荷转移更不易进行，造成了光谱较大的蓝移。

The orifice of a gamoptelous corolla or gamosepalous calyx; the expanded portion of the corolla between the limb and the tube.

喉 Throat 合花冠或合生萼的开口，图 1792；冠筒与冠檐之间花冠的宽展部分。

Corona lobes separate, inserted at base of gynostegium, linear-subulate, longer than gynostegium and exserted from corolla tube.

副花冠裂片分开，合蕊冠，线状钻形，长于合蕊冠和从花冠筒外露的着生的在基部。

Carpesioides is 2n=18=14m+2sm(2SAT)+2st in two populations. The two species under study represent two sections of Nannoglottis s.l. N. gynura, the only species of sect.

狭舌毛冠菊两居群的染色体数目与核型公式为2n=18=14m+2sm+2st(2SAT)；毛冠菊两居群的染色体数目与核型公式为2n=18=14m+2sm(2SAT)+2st。

Methods: The distal 1/3 of eighty humeri was scanned by 16 layer spiral CT. The morphologic features of the intramedullary bony prominence above the olecranon fossa were observed and described on coronal, sagittal and transverse section after three-dimensional reconstruction. Then the distal 1/3 of twenty humeri was splitted vertically along the coronal midline for observing the intramedullary bony crista.

应用16层CT对80根肱骨远段1/3进行扫描，三维重建成像后，从冠状面、矢状面和横截面观察并描述鹰嘴窝上髓腔内骨性突起的形态特点，然后将20根肱骨远段1/3在冠状面上从中线纵行剖开，对髓腔内骨嵴行直观的观察。

Hystrix canopy declined slightly at the midday, suggesting the occurrence of reversible photoinhibition. Owing to the lower maximum net photosynthetic rate in sun leaves and the ability to effectively and consistently utilize the scattered light and/or transmitted light, C. hystrix saplings could survive low light intensity, grow well at the edge of the forest and in the understorey, and eventually become one of the dominant species in upper layer of the community.

刺栲冠层阳生叶的最大光合能力比较低，整个冠层叶能高效而稳定地利用散射和透射光，这些特征使得常绿的刺栲幼树能在林边或林下良好生长，较好地适应不同的光环境并成功渡过幼苗期，最终成为群落中的上层优势种。

On the one hand, The empirical model is remedied to investigate themicrowave emissivity of sea surface under wave breaking. In this model, we havediscussed the effects of spherical bubbles and droplets of whitecaps and difference intemperature between air and sea water on the emissivity of sea surface. Themodel results indicate that the effective seawater emissivity increases with DTBASincrease.

在被动遥感方面提出了一个改进的研究海浪破碎产生白冠时海水有效发射率的模式，讨论了白冠层中主要成分为球形气泡和水滴的情况，并着重分析了海-气温差对海水发射率的影响，研究表明海水发射率随着海-气温差的增大而增大。

Methods The solid sections of hepatic segments were obtained by liver incision according to the lines of surface projections of each hepatic fissures The structural landmarks were on lines of section which were observed Results There existed the structural landmarks on the solid sections of median fissure,right interlobar,right anterior lobe,right posterior liver lobe and left hepatic lobe fissures They were showed on the solid images of three dimensional ultrasound.

所谓三维超声立体断层图是指在同一幅超声图像中，同时显示器官或病灶的冠状面和矢状面，或者同时显示冠状面和水平面，或者同时显示矢状面和水平面，构成&蛋糕块&状的立体图像 [1] ，而不是凸凹不平的&立体感觉&。

The formation mechanism for the C-PPV aggregation we proposed is: complex between K+ and the crown ether derivatives in the C-PPV brings two polymer chains closer together, and the K+ ions create interpolymer bridges, forming aggregations in the solution.

本文合成了可溶的带冠醚取代基的聚苯撑乙烯，其中冠醚基团的氧原子直接连在PPV主链上苯环的2、3位，并研究了聚合物在K~+存在下的自组装形成聚集体的行为。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
