矿井运输巷道的潮湿和煤尘造成运输条件恶劣，巷道分支多和照明光线弱造成行车视线距离短。
Moisture, coal dust, multiple roadway branches and others in a mine transportation roadway would cause series transportation conditions.
其实，若是在自然光下、于水中一段距离外，这种图案和色彩有助于扭曲鱼的轮廓，让它在潜在掠食者的视线中消失。
The pattern and colors actually help distort the fish's outline when seen in natural light at a distance through water, helping the animal disappear from the view of potential predators.
眼睛大而圆，不外突，两眼间距离恰当，视线笔直向前。
Eyes - Large, round, not prominent, placed well apart, looking straight ahead.
如果雷雨狂风影响视线，行驶速度参考前车，能降多低就降多低，安全距离应该拉长。
If the thunderstorm the influence line of sight, speed, can drop the reference how low it came more low, safety distance should be stretched.
但闫平拉大或加强了这种瞬间错觉弥补的距离，比如，塞尚至多在几厘米之间移动他的视线，来形成距离移动感。
But Yan widens or reinforces the distance made up by the momentary illusion. For example, Cézanne would move his sight between few centimeters to form a distance with a sense of moving.
并利用电扇作为目标，测试了目标距离及不同档风速下的目标视线速度。
The range of an electric fan as well as the line-of-sight fan speed of different levels is tested.
无论是时间的距离，还是空间的距离，都无法隔断我们的视线，每天晚上，我们不是都在思念中相见吗？
Neither time nor distance parts our sight. We meet each other in missings each night.
由于大气衰减的影响，非视线散射大气光通信需要使用光学天线以提高对光信号的采集能力，进而增加通信距离。
The primary function of the optical transmit antenna is to collimate far-field divergence of the laser beam and reduce the size of the laser beam in .
