Another way to safely view the eclipse is to use a pinhole viewer.

另一种安全观看日食的方法是使用针孔观察器。

Pinhole bored dwellings suggest that our sulfuria grows in them more abundantly than might be expected.

针孔住宅表明我们的硫磺在其中的生长比预期的要多。

Buildings that have a combination of copper and galvanized steel are susceptible to pinholes and corrosion caused by the mobility of ions in the water.

水中离子的移动性会导致水管壁中出现气泡和腐蚀现象这些现象会危害建筑中镀锌结构和铜结构的坚固性。

If you don't have these filters you can still observe the eclipse by making a pinhole camera using materials from around your home.

如果你没有滤光片，你可以选择使用针孔摄像机，用一些家周围的材料就可以制作。

The American Astronomical Society also suggests watching the eclipse indirectly through a pinhole projector, or through binoculars or a telescope fitted with special solar filters.

美国天文学会还建议通过针孔投影仪间接观看日食，或者使用配备了特殊太阳滤镜的双筒望远镜或望远镜。

And if you’re looking for a safe way to see the eclipse, we’ve got you covered with our special SciShow pinhole projector card!

Now your pinhole projector is ready, so you can head outside, make sure the sun is behind you, hold the projector up to your eye, and then look for sunlight to come into the projector.

现在你的针孔投影仪已经准备好了，这样你就可以出去观测了，确保太阳在你的背后，将投影仪放在眼睛前，然后等待阳光进入投影仪。

He was probably familiar with the camera obscura, a device that projected an image through a pinhole and onto a screen in a darkened chamber (new research suggests he may have been introduced to it by the Jesuits of Delft).

维米尔可能对暗箱技术很熟悉，这种装置可以让图像透过小孔，投映到光线较暗的室内幕布上。(新的研究表明，这种技术可能是代尔夫特的耶稣会士介绍给他的)。
