这种个体最明显的特色就是在照射充分光线下，全株会展现出鲜红色调的样子喔！
The most distinct characteristic of this form is the bright red hue that this trap takes on when it is exposed to plenty of sunlight.
该遮光板组装在该灯座上并位于该发光件与透镜间，该遮光板用于遮挡发光件所发出的部分光线。
The shading plate is assembled on the lamp holder and positioned between the illuminating part and the lens, and is used for shading partial light emitted by the illuminating part.
如果光线被玻璃或者半导体表面反射的话，贴膜会改变其中大部分光线的方向使其重新射回太阳能板。
If light does reflect off either the glass or semiconductor surfaces, the film redirects much of it back into the solar panel.
一块红色的大方格地毯覆盖了整个门厅，安装在窗帘盒（挡住窗帘轨道的木制品——译者注）里面窗帘遮挡了大部分光线。
There was a big red check carpet running throughout the hall and curtains with pelmets which took away a lot of the light.
要把光被捕获在两维的曲线状表面上时，要求物体表面非常平滑，才足以把大部分光线干净利落地反射进油层而不是分散在所有的各个角度上。
For the light to be trapped in two dimensions, the object's surface needed to be smooth enough to cleanly reflect most of the light into the oil layer rather than scattering it at all angles.
这种木屋顶结构拉低了整个住宅的层高，而且还为两个阳台遮挡部分光线，避免阳光直射，重要的是为主人提供了隐私，限制了室外往室内看的可能。
The wooden roof structure is pulled down over the top storey of the house, shading two terraces from the elements and restricting views of the interior space.
由于阵列化laps一般采用LED阵列作为激励光源，而LED的发散角较大，所以在实际应用中难以避免有部分光线会照射在各敏感区域之间的非敏感区域上。
LAPS array usually USES LED array as stimulative light source. LED has a large divergence Angle, so it is difficult to avoid some light irradiating on the non-sensitive area between sensitive areas.
然后你通过分光器发射一束激光，让光线在两条边不断反射再回到分光器。
Then you send laser light through a beam splitter to divide the beam between the two arms, and let the light bounce back and forth a few times before returning to the beam splitter.
