In conclusion, we find that the speed of light in a vacuum has a constant value regardless of the movement of the observer (our observations from the moving Earth), or the movement of the source of light (our observations of light emitted from the moving pion).
在这个结论中,我们发现真空中的光速有着恒定值,不管观察者的如何运动(我们的观察是在运动的地球上),也不管光源如何运动(我们观察的光由运动的介子发出)。

It is presumable that originally their light was merged in that of the earth's own outer covering of light, and that as her luminous envelope disappeared they became visible, and she came to depend on them for both light and heat.
这是presumable最初合并了它们的光线在这地球的自己的外壳的光,而且因为她的明亮的信封消失了,他们成为看得见,她来到取决於他们对光和热。

He makes a record of 2,500 planets visible in central China and the first star Chart of the country. Regarding the formation of the Lunar eclipse, he makes the correct interpretation that the moon itself does not give light but reflects the light from the sun, that the dark part of the moon is the part that receives no light and that the full moon is seen when the moon and the sun are in the opposite positions; when the moon moves to the same direction with the sun towards the earth, the lunar eclipse is seen.
记录了中原地区能看到的2,500颗恒星,并且画出了中国第一张完备的星图,正确解释了月食成因:月亮本身不发光,受到太阳的照射才反射出光来;月亮的黑暗部分,就是没有照射到太阳光的部分;月亮的位置和太阳相对的时候,就是满月;月亮运行到跟太阳同一方向的时候,就是月食。

We found out one kind of new orange-red long afterglow material La2O2S: Eu3+, Mg, Zr.2 In the phosphor Gd2O2S, Mg, Ti which was prepared by high-temperature solid-state method, the orange afterglow phenomenon can be seen after illuminated with UV light.3 Using the high-temperature solid-state method, Gadolinium oxysulfide phosphors doped with rare earth ions were synthesized. We can observe the red or orange phosphorescence in Gd2O2S doped with Eu3+, Sm3+, Tm3+, Yb3+, Dy3+, Er3+, Nd3+or Ho3+. This is a new result of the long afterglow phosphors research.4 Using the microwave radiation method, the new Sm3+ doped gadolinium oxysulfide phosphor, which has the orange-red long afterglow emission after illuminated with UV light or visible light, was synthesized for the first time.5 In fluorescent materials YOX doped with europium ions, the long afterglow phenomenon wasnt observed but the blue luminescence of Eu2+ and red luminescence of Eu3+ are simultaneously examined. This is a new result of the valence stability and change of Eu2+ in yttrium oxyhalide .We systematically studied the effects of the host, addition agents and reaction atmosphere on the valence change and fluorescence property of europium ions.
经过系统的研究总结得到以下的结论与成果: 1采用高温固相反应法合成了一系列稀土离子掺杂的硫氧化镧发光粉,发现了该体系中Eu~(3+)的长余辉发光,从而得到一种迄今未见文献报道的红色长余辉发光材料:La_2O_2S:Eu~(3+),Mg,Zr; 2在Gd_2O_2S,Mg,Ti磷光粉中观察到橙色的长余辉发光现象; 3采用高温固相反应法合成了一系列稀土离子掺杂的硫氧化钆磷光粉,在掺杂Eu~(3+)、Sm~(3+)、Tm~(3+)、Yb~(3+)、Dy~(3+)、Er~(3+)、Nd~(3+)、Ho~(3+)的Gd_2O_2S中观察到红色和橙色长余辉发光; 4首次采用微波法合成了Gd_2O_2S:Sm~(3+),Mg,Ti磷光粉,该磷光粉经紫外或可见光激发后呈现明显的橙红色长余辉发光; 5在YOX中同时观察到Eu~(2+)和Eu~(3+)的发射,系统研究了基质、添加剂及反应气氛对Eu价态和发光的影响。
