A systemic research on the birefringence of side-hole fiber is presented. The research results show that the birefringence of circular-core side-hole fiber relies mainly on stress birefringence, its fast axis is parallel to the link line of the two holes, and its intrinsic birefringence increases exponentially with the angle and ellipticity of side holes.

本论文的主要研究结果和创新在于： 1、对边孔光纤的双折射特性进行了系统研究，提出圆芯型边孔光纤以应力双折射为主，两边孔连线方向为其快轴方向，其双折射大小与边孔张角和边孔椭圆度成指数关系。

In this study, it was analyzed how the hole formed and the hole patching method can be used.

Attachments on the string are permitted to serve as a lip or nose mark, a peep-hole, a peep-hole 'hold-in-line' device, loop bowstring, etc.

允许在弓弦上附加物件当作唇珠或鼻珠，如瞄准孔、弦上瞻孔、环式弓弦等。

At each penton, a hole (φ=20〓) can be seen connecting the inside and the outside of the capsid, and there is a hole (φ=12〓) at each hexton and the center of 2-fold axis, so there are 132 holes in total at the surface of CSBV.

应用冷冻电镜技术和计算机三维结构重构的方法，我们测定了CSBV核衣壳的三维结构，分辩率为25 〓，病毒的核衣壳是按T=1（P=3）的对称结构排列二十面体，病毒表面比较光滑，有12个五邻体、60个六邻体的结构，每个五邻体的中央有孔洞，六邻体的中央也有孔洞，另外在2次轴的位置上也有孔洞，这样病毒共有132个孔洞，五邻体的孔洞的直径为20 〓，而六邻体和二次轴的孔洞的直径月为12 〓。

翻译是：结果是，当比赛并没有发现明确的顶端是进一步的动作是必需的。在这一点上一薄有机玻璃盘的中心位置以便先端最最跟踪在中心孔和附属于铜盘用黏稠的蜡。

If under ideal conditions, one electron-hole pair injected yields one blue photon and the quantum efficiency of the phosphor equals one, the numbers of electron-hole pair must equal to the numbers of white photons. So LW white LED radiation power output has to consume 1.51 W electric powers and the luminous flux efficiency limitation of electrical to optical conversion for the white LED is 197.8lm/W at above condition.

在理想情况下，注入一个电子－孔穴对产生一个蓝光光子，设荧光粉的量子效率为1，因此，注入的电子－孔穴对数亦等于白光光子数，进而计算出白光LED每辐射1W的光功率所需的电功率为1.51W，上述白光LED发光光谱对应的白光LED的电－光转换的理论极限流明效率为197.8lm/W。
