查询词典 cavities

When they are still closer, the ensemble properties dominate and the electrons "delocalize": they are no longer tightly bound within individual cavities but are more or less free to pass through the spaces within the framework of positive ions.

当它们间的距离更近时，群体集合属性更占主导地位，而且电子也出现&离位&现象：它们不再被束缚于单个的空穴之上，而是或多或少地可以在正离子的构架之间穿越。

As an artificial enzyme, it can be optimized by changing the diphenylmethane units or bridging chains or by chemical modification of hydrophobic cavities to form new host compounds. Different host compounds can recognize different guest compounds to become an supramolecular system.

不同的主体化合物能俘获不同种类的客体分子，与客体形成超分子体系，对不同反应底物进行络合和催化，达到有选择性地控制反应，提高反应速率，模拟酶促反应和分子识别的目的。

EPR study of the thermal products of these montmorillonites shows that g = 2. 14 signal relates with hydrated copper ions existing in the interlayer of montmorillonites and g = 2. 07 signal relates with Cu~(2+) occupying the ditrigonal cavities of Si-O sheet. And, the supper fine line of g ca. 2. 2 - 2. 7 suggests Cu~(2+) migrating into octahedral vaeancies.

同时，该蒙脱石热处理产物的EPR研究表明、g=2.14信号与蒙脱石层间的水合铜离子相关， g=2.07信号和g为约2.7-2.2超精细结构线分别与进入了粘土矿物Si-O四面体片复三方形孔洞和铝氧八面体空位中的Cu相关。

Methods Guinea pigs suffering from SOM were divided into three groups randomly, 6 for each group. Ectogenic surfactant, dexamethasone and 0.9% sodium chloride solution were injected into guiea pigs' tympanic cavities of group A, B and C respectively. The biochemical components and activity change of surfactant of Eustachian tube were analysed.

将分泌性中耳炎豚鼠动物模型随机分为A、B、C3组，每组各6只（12耳），分别用外源性表面活性物质、地塞米松和生理盐水注入豚鼠中耳腔内，然后观察豚鼠中耳变化；分析豚鼠咽鼓管内表面活性物质的生化成分和活性变化。

On the industrial experiments the effect of electromagnetic stirring on central porosity ,equiaxial crystal ratio,shrinkage cavities and surface quality as well as effect of electromagnetic stirring on the solidification of the continuous casting billet have been analyzed and discussed.

根据工业试验结果，分析了结晶器电磁搅拌对马氏体不锈钢连铸坯的中心疏松、等轴晶率、缩孔及表面质量的影响，并对电磁搅拌对铸坯凝固的影响机理进行了探讨。

Accessory nasal cavities with ACC always involved ethmoidal and sphenoidal sinus.

副鼻窦ACC易累及筛窦和上颌窦。

Methods Radiofrequency thermo-coagulation via nasal endoscope was applied in 65 allergic or vasomotor rhinitis patients to the areas in bilateral nasal cavities where vidian and anterior ethmoidal nerves concentrated. The postoperative symptoms' score was compared with the preoperative one.

对65例病人在鼻内镜下对双侧鼻腔翼管及筛前神经丛集区行射频热凝，降低神经兴奋性和敏感性，术后1个月、6个月、1年后进行随诊，根据症状改善情况评价疗效。

The ability to chew declines, and people shift to softer foods, which are generally higher in fermentable carbohydrates and more likely to cause cavities.

咀嚼能力的下降，以及人们转向于食用更软的容易发酵的碳水化合物，这些都可能会造成牙齿空洞。

The results indicate the membrane prepared in pure water coagulation bath exhibits fingerlike structure, with an increase of the volume fraction of ethanol in coagulation bath leads to a reduction of fingerlike cavities, and in ethanol/water coagulation bath of φ=40% exhibits spongelike structure; the melting points of the fingerlike and spongelike membrane increase by 3.9℃ and 3.5℃ compared to that of raw material respectively, and the crystallinity of the two type membranes increases by 16.1% and 13.5% respectively.
