查询词典 atom

A layer of tin atoms on a germanium surface forms a flat lattice, but at temperatures below about 150 Kelvin--for reasons that aren't entirely clear--the tin layer spontaneously corrugates to form a new structure, or phase, with one atom out of every three moving away from the substrate.

一层锡原子在锗表面可以形成一个平整的晶格，但是当温度低于150K锡原子层会自发的褶皱起来形成一种新的结构，或者说是新相，这时每三个原子中会有一个运动而离开基质表面。

This is defers to the carbon atom to enlarge 400,000,000 times to make.

这是按照碳原子放大4亿倍做成的。

The main reason of complex with greater nonlinear refractive index is that the complex has larger conjugated delocalized system and there are electrons shifting between ligand and metal atom.

选择具有π键的配体与金属离子合成为配合物，使其非线性效应明显增强，这对合成性能更好的非线性材料有一定的参考价值。

Although benzene is often represented with alternating single and double bonds between carbon atom s, the electrons in the bonds are shared or delocalized in such a way as to make all carbon-carbon bonds alike.

虽然往往把苯描绘成碳原子之间按单、双键交替排列，但事实上键中的电子是共享的，或者说是非定域的，其结果是使所有的碳原子都是等同的。

Active hydrogen atom and oxygen ion form Hydroperoxy radicals which surround the positively charged biological contaminants, and then react with three hydrogen elements of its protein structure, destroying and detoxicating the biological contaminants nature.

活性氢和氧离子(O2-)形成的氢过氧自由基，会包围着带正电荷的生物污染物，每一枚黏附在污染物表层的氢过氧自由基，会与其蛋白质结构中三个氢元素产生反应，完全破坏其结构，变成无毒状态。

An incident photon of high enough energy dislodges an electron from the atom, leaving a positively charged ion.

能量足够高的一个入射光子从原子中击出一个电子，剩下一个带正电的离子。

Integration and dispelling of molecule and atom form all creatures' living and death.

分子、原子在聚散之间，形成了众生物的生与死。

It emits a magnificent amount of X-ray, which is used to reveal the atom structures.

它是目前世界上最大的X光机，因为在电子在曲线运动时会放出x光。它被用来揭示原子的结构

After the lanthanon atom Ce is encaged, the volume of each isomer cage expands slightly, which leads the cluster more stable.

在掺入稀土金属原子Ce之后碳笼的体积有略微的膨胀，且该原子的掺入能够得到更稳定的团簇。

The experiment studies revealed Atom Force Microscope observed vital human erythrocytes that incubated at different temperatures in plasma physiological environment, that surface microstructure of the cell membranes were shapely sensitive to the altered temperature increasingly, and that liquid crystalline state bio-membrane were slightly perturbed and happened phase transition. In the optical tweezers experiment, the captive erythrocytes were encaged in the three-dimensional laser optical potential well, and able to well maintain physiology characteristic property and intact shapes.

实验研究显示，在血浆生理环境中不同温度孵育的红细胞经原子力显微镜观测，其膜表面微观结构对温度变化比较灵敏，液晶态生物膜被扰动而发生轻微相变；在光镊捕获实验中，三维激光势阱囚禁的红细胞却仍能够维持良好生理特性和完好形态，并且细胞膜表面存在相互作用力。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
