This was intended to exclude the direct rays of the sun 其目的是阻挡直射的太阳光。
Humans have no direct perception of infrared rays unlike the rattlesnake which has receptors tuned into wavelengths longer than 0.7 micron. 与响尾蛇不同,人也不能直接感受到红外线。响尾蛇的感觉器可以感受波长超过0.7微米的光线。
So, throughout the year, different parts of Earth get the sun's direct rays. 因此,全年不同地区得到太阳的直接辐射不同导致季节变化。
If so, wouldn't it be more correct to say that the life forms that live on it are still dependent on energy from the sun, just not its direct rays of light? 如果是这样的话,是否可以说以它生活的生命还是靠太阳能呢,只不过是间接的方式而已?
She drew the blinds down to keep out the direct rays of the sun. 她将百叶窗拉下以防阳光直射。
They hung up there in the sky just like it belonged to them, and even had the nerve to direct rays of sunlight at us. 它们悬挂在空中,好像天空是它们似的。它们厚颜无耻,居然把阳光射向我们。
This might include moving them a little further from an open window ( just outside the direct rays), or aiming your flash at a nearby wall or ceiling. 这也许包括移动它们有点进一步从开着的窗户外面的光线(直接瞄准你的闪光灯),或在附近的墙壁或天花板上。
Based on radiant properties of direct beam radiation, diffuse radiation, solar spectrum and 32/ solar radiation angle, radiant position, radiant direction, wavelength spectrum and radiant energy of entering rays were researched, relevant algorithms are developed and tested. 通过考虑直射辐射、散射辐射、太阳辐射的光谱分布以及太阳辐射32/张角等影响因素,研究了模拟射线的辐射位置、辐射方向、波长分布及辐射能量的相关算法,并进行了数值计算验证。
The onboard display surface will be not only affected by the direct rays of the sun, but also by the reflection from the sun in the cockpit lighting and diffused lighting. 机载显示器表面不仅会受到太阳的直接照射,还会受到驾驶舱内来自太阳的反射照明和漫射照明。
