As a result, if the iridescence is produced by thin-film interference, not only the thickness of lamellar structure must be defined within a certain nanometer, but also the refractive index need to be different between lamellar structure. In other words, the chemical composition, refractive index and thickness of exsolution lamellae need form to trinity, such as labradorite, albite, andradite and orthoamphibole. If the iridescent color is produced by grating-diffraction, the lamellar structure just needs to be arrayed regularly, the spacing of the edges of lamellar structure needs to be regular and narrow, but not necessarily within the range of the wavelength of visible light, such as shell of abalone, pearl and opal.

薄膜干涉式晕彩不仅要求宝石内部结构层的厚度必须在一定的纳米范围内，而且结构层内部的折射率也必须有所差别，也即，当结构层由两相组分出溶而成，其化学成分、折射率和结构层厚度形成三位一体时，符合薄膜干涉式晕彩，如拉长石、钠长石、石榴石和角闪石；而光栅式衍射晕彩则仅要求结构层排列规则，边缘狭窄但不需要窄到可见光波长范围内，能使入射光的振幅或位相，或两者同时产生周期性空间调制的结构即可，如鲍贝壳、珍珠和欧泊。

I mean sitting on horsecar like this,walking on bushmusic bigdao like this,I'm so happy that i dizzy car.

我是坐着这样的马车，走在这样的林荫大道上，我开心得晕了，陶醉得晕了，享受得晕了，所以，我就晕车了。

简要介绍了中子晕和质子晕研究的最新实验进展，同时，讨论了近年来发展的同位旋，能量有关的具有晕核结构的 Glauber理论及它在描述晕核与核散射时的重要性。

Healthy volunteers participated 6 experiments that were designed to test the sensory conflict theory of motion sickness, to observe the effect of the outside proprioceptive input on motion sickness and to make sure the influence of motion sickness susceptibility, automatic nerve activity and breed on experimental nausea and vomiting. The results were as follows: 1. Different intensity of visual and vestibular sensory conflict effected the onset of vection and rotation toleration time and the symptoms of nausea and vomiting, the more intensive of confliction, the more quickly onset of vection, the more short rotation toleration time, and the more serious symptoms of nausea and vomiting.

本研究针对上述问题设计了6个实验，以200名健康成年志愿者为被试，以转椅和转鼓作为诱发实验性晕动的装置，采用恶心评定量表、恶心问卷和晕动敏感史量表及自我运动错觉和旋转耐受时间为指标，旨在考察：（1）实验性恶心、呕吐症状的时间变化规律；（2）不同强度感觉冲突、不同体位因素对实验性恶心、呕吐的影响，验证晕动的理论假设；（3）晕动敏感史差异、人格因素、种族因素与实验性恶心、呕吐的关系。

Methods The superficial skin upon the triangular areolar flap was reserved to maintain the original shape of the orela. The tension force of the incision suturing in the traditional method was also reduced.
