美国密西西比州论文代写:视力受损

一个天生失明的人有梦想,但没有看到图像。梦想可能包括声音,触觉信息,气味,味道和感受。另一方面,如果一个人有视力然后失去它,梦想可能包括图像。视力受损(法定失明)的人确实在梦中看到了。梦中物体的出现取决于失明的类型和历史。大多数情况下,梦中的愿景与人们一生中的视觉范围相当。例如,有色盲的人在做梦时不会突然看到新的颜色。视力随着时间的推移而退化的人可能会以早期的完美清晰度梦想,或者可能梦想当前的敏锐度。有视觉矫正镜片的人有相同的经历。梦想可能完全成为关注焦点。这一切都基于随着时间的推移而积累的经验。一个盲人但感知Charles Bonnet综合症的闪光和色彩的人可能将这些经历融入梦想中。奇怪的是,即使他们没有在梦中看到图像,在一些盲人身上也会出现快速眼球运动,这种运动是REM睡眠的特征。当一个人自出生以来失明或者在很小的时候失明时,更有可能发生快速眼球运动的情况。 美国密西西比州论文代写:视力受损 A blind person has a dream but does not see an image. Dreams may include sound, tactile information, smell, taste and feeling. On the other hand, if a person has vision and then loses it, the dream may include images. People with impaired vision (legal blindness) do see it in their dreams. The appearance of objects in a dream depends on the type and history of blindness. In most cases, the dream vision is comparable to the visual range of people in their lives. For example, people with color blindness do not suddenly see new colors when they dream. People whose vision has degraded over time may dream of early perfect clarity or may dream of current acumen. People with vision correction lenses have the same experience. Dreams may be completely the focus of attention. It's all based on the experience accumulated over time. A blind person who perceives the flash and color of Charles Bonnet syndrome may incorporate...

美国密西西比州论文代写:凯克天文台

凯克天文台及其两个10米宽的望远镜坐落在夏威夷的莫纳克亚火山山顶上。这些双光望远镜对光学和红外光敏感,是世界上最大和最具生产力的仪器之一。每天晚上,它们都能使天文学家能够观察到与我们太阳系世界一样近的物体,以及远离宇宙中一些最早的星系。凯克天文台有两个10米长的镜子,每个镜子由36个六边形元素组成,它们作为一面镜子一起工作。每个镜子重300吨,由270吨钢支撑。每个望远镜穹顶的体积超过700,000立方英尺。圆顶全天冷却并保持在冰点或低于冰点温度,以防止镜子因热而变形。凯克天文台是第一个使用自适应光学和激光导星的主要设施。它现在使用了近十几种仪器来成像和研究天空。未来的仪器包括行星探测器和宇宙测绘仪。 W.M.凯克天文台使用最先进的仪器观察宇宙,包括一些帮助它解剖远处物体的光。这些光谱仪以及红外摄像机使Keck始终处于天文研究的最前沿。近年来,天文台还安装了自适应光学系统,帮助其镜子补偿可能模糊视野的大气运动。这些系统使用激光在天空中创造出“引导星”。 美国密西西比州论文代写:凯克天文台 The W.M. Keck Observatory and its two 10-meter-wide telescopes are located on the top of Mount Mauna Kea in Hawaii. Sensitive to optical and infrared light, these dual-lens telescopes are among the largest and most productive instruments in the world. Every night, they enable astronomers to observe objects as close to our solar system as possible, as well as some of the earliest galaxies in the universe. The Keck Observatory has two 10 meter long mirrors, each consisting of 36 hexagonal elements that work together as a mirror. Each mirror weighs 300 tons and is supported by 270 tons of steel. Each telescope dome has a volume of more than 700,000 cubic feet. The dome cools throughout the day and stays at or below freezing to prevent the mirror from deforming due to heat. The Keck Observatory is the first major facility to use adaptive optics and laser guides. It now uses nearly a dozen instruments to image and...
