光子

In 1966 Kenneth Greisen, Vadim Kuzmin and Georgiy Zatsepin showed that high-energy charged particles (cosmic rays are mostly atomic nuclei, and thus positively charged) should be slowed by collisions with the photons of the cosmic microwave background (radiation left over from the Big Bang that permeates all space).

扎采品表示，充有高能量的粒子（大多数太空射线都属于原子核，因此也就具有正电）应该会由于太空微波背景下（渗透到整个宇宙的大碰撞所遗留下的辐射）的光子碰撞而减慢速度。

The group velocity dispersion properties of photonic crystal fiber were investigated in detail by equivalent index model.

应用等效折射率模型对折射率导模光子晶体光纤的群速度色散特性进行了详细的讨论。

Numerical simulation on propagation of ultra-short laser pulse in photonic crystal fibers with different group velocity dispersion parameters.

超短激光脉冲在不同色散参量光子晶体光纤中传输的数值模拟。

This conclusion provides theoretical and experimental references for controlling the group velocity of light by means of one-photon detuning.

结果表明，由于多普勒展宽效应的存在，在单光子频率失谐±600MHz范围内，光减速现象较为显著。

Of our famed rods and cones, the two classes of light-sensing cells with which the retina at the back of each eye is supplied, the rods do the basics of vision, of light versus shadow, tracking every passing photon and allowing us to see by even a star's feeble flicker, though only in gunmetal shades of black, white and grim.

在我们眼球后面的视网膜上有锥状和柱状两类感受光亮的细胞。柱细胞承担视觉的基本操作，分辨明暗，跟踪光子，使我们透过那怕只是由黑白蓝调出的铁灰色，也能看见遥遥星空的闪烁。

An all-optical half adder based on two different cross structures in two-dimensional photonic crystals was proposed. One cross structure contains nonlinear materials and functions as an "AND" logic gate.

提出了基于两种二维光子晶体"十字"逻辑门的全光半加器，其中一种"十字"结构含有非线性介质，起"与"作用，另一"十字"结构不含非线性介质，起"异或"作用。

I this is at that time, the opinion with peacockish true girl is full of in a heart.

这就是当时的我，一个心中布满虚荣的女孩子真实的想法。
