With advantages such as energy saving and long lifetime GaN-based vertical LED will be widely used in general illumination scene lighting special lighting and auto lighting .

GaN基 垂直结构LED具有耗电量小、寿命长等优点，在通用 照明、景观照明、特种照明、汽车照明中被广泛应用。

Design of Annular Lens Dark Field Vertical Illumination System and Its Focal Distance Offset Characteristics

环形透镜 暗场落射 照明系统设计及其焦移特性的研究

Rats in the stressed group were irregularly and alternately exposed to the situation of vertical revolution sleep deprivation noise stimulation and night illumination 6 h per day for 6 weeks to prepare a chronic multiple stressed model .

采用 垂直旋转、睡眠剥夺、噪音刺激和夜间 光 照4种应激原，无规律地交替刺激动物6周，每天6h，制作慢性复合应激动物模型。

Experimental results show that the method can achieve effective face tracking under the condition of camera rotation in horizontal direction or camera translation in vertical direction variety of illumination movement of head similar color distribution of background and face region .

实验结果表明，算法在摄像机转动、仰 俯、 光线变化、人头晃动以及背景颜色分布与人脸近似等情况下均可完成有效跟踪。

The chronic multiple stress model was established by irregular and alternative exposure to vertical rotation sleep deprivation restraint ( 6h / d ) and night illumination for 6 weeks .

应激组动物进行6周的 垂直旋转、睡眠剥夺、捆绑（6h/d）和夜间 光 照等慢性复合性应激试验；

The rats in multiple stress group were alternatively exposed to the situation of complex stressor every day ( sleep deprivation vertical conbolution noise stimulation and continuous illumination ) for 6 weeks . Those in control group were without intervention .

复合应激组动物每天交替暴露于复合应激原环境（睡眠剥夺、 垂直旋转、噪音刺激和持续 光 照）中达6周，对照组动物不干预。
