光反射

Photophobia, weep: Often happen with companion of look painful look, this is the reflection action be caused by that trigeminal nerve suffers stimulation, have palpebral convulsion at the same time.

畏光、流泪：经常与眼痛相伴发生，这是三叉神经受刺激的反射作用所致，同时有眼睑痉挛。

The Ti-sapphire resonance cavity is composed of second plane reflector, Ti-sapphire crystal and second plane output mirror.

钛宝石谐振腔由在光路上依次连接的第二平面反射镜、钛宝石晶体和第二平面输出镜组成。

A device for measuring bidirectional reflectance and transmittance distribution of a leaf in the plane of incidence was designed with a micro-powered laser diode for illuminating and a silicon photocell detector rotating around sample for recording scattering light intensity from the sample.

采用微功率激光管作为光源，围绕被测样品旋转的硅光电池作为检测器，研制了一种可以测定植物单个叶片反射和透射光在入射面上分布的装置。

Crystals are platy in form with the grain size generally measuring 0.1×0.2×0.01mm.

在光片中矿物呈黄白色，双反射弱，Rp≈Rg=12—14％，弱非均质性；Hv(50)=520—580kg/mm~2。

Topics covered include, the properties of light and its interaction with mineral grains: reflection, refraction, polarisation, interference phenomena, extinction, colour and pleochroism. Refractometry inclusive isotropic, uniaxial and biaxial optics and the interpretation of interference figures. Transmitted light petrography in the identification and familiarisation with major rock forming minerals in grain mounts and thin section.

讲稿内容涉及到光学属性分析与矿物交叉面相互反应，具体内容有反射、折射、偏振、光干涉现象（包括等方性、单轴、二轴光学及干涉数据解释）、岩石记述学、矿物的光学属性鉴定等方面。

This exhibit uses the principle of light reflection.

利用了光的反射原理。

Unlike current diffuse reflectance visible spectroscopy, the visible microspectroscopy can obtain the cell-level spectral information, It is not affected by changes of optical path length induced by different set-up of prober and hemoglobin concentration due to the pressure between prober and tissue.

对比常见的漫反射可见光谱技术，可见光显微光谱技术能够获取细胞大小范围内的信息，而且不受探头结构差异导致的传输光程长短，以及测量时探头施加压力导致的血红蛋白浓度异常变化的影响。

Then by measuring the pulse wave propagation time between the progressive wave and reflected wave, we can find the relationship of the time and the blood pressure, and establish the related systolic blood pressure measurement equation.

具体方法是通过交替点亮红光和红外光获取容积脉搏波，经放大滤波及信号处理后得到加速脉搏波，通过测量其中推进波和反射波之间的脉搏波传播时间来建立与血压的关系。

Because it reflects the rays of the sun.

不能。因为它是反射太阳的光。

Results there were unconsciousness, respiratory rhythm disturbance and hyporeflexia of pupil light reflex immediately after injury, and reactiveness decrease and activity retardation still existed even after resuming consciousness. at anatomical scene, subarachnoid hemorrhage or cerebroventricular haemorrhage were widespread. at an early stage, there were swelling, collapse, and axonal retraction ball formation at cortico-medulla junction, callosum, brainstem, and cerebellar white matter under microscope. but at the later stage, gitter cell proliferation and nest-like aggregation were major pathophysiological changes at focal brain tissue.

结果 伤后大鼠均即刻出现原发昏迷，其中2只于损伤后20 min内死亡，余持续时间1-30 min不等；伤后大鼠呼吸节律紊乱，瞳孔对光反射减弱或消失，醒后均有程度不等的反应性下降，肢体活动迟缓；肉眼可见广泛蛛网膜下腔出血或脑室出血；光镜下可见皮髓交界区、胼胝体区、脑干、小脑白质等部位的神经轴索有不同程度的肿胀、断裂、轴索球形成，后期有小胶质细胞增生，局部呈巢样聚集。

I will endeavour to find you some assistance.

我尽力帮你找人帮忙。

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
