数据处理结果表明X轴进给传动系统载荷服从形状参数为1.699、尺度参数为7.596的伽玛分布；Z轴进给传动系统载荷服从形状参数为1.077、尺度参数为5.905的伽玛分布。

We learn that sodium or any of its compounds produces a spectrum having a bright yellow double line by noticing that there is no such line in the spectrum of light when sodium is not present, but that if the smallest quantity of sodium be thrown into the flame or other souces of light, the bight yellow line instantly appears.

当我们把很少的一点钠投入火焰或其它光源中时，我们会立刻看到光谱中出现一条鲜黄色的双线；当钠不存在时，光谱中的这条线也就消失了。由此我们知道，钠或任何钠的化合物所产生的光谱都带有一条鲜黄色的双线。

Compounds produces a spectrum having a bright yellow double line by noticing ① that there is no such line in the spectrum of light when sodium is not present ,② but that if the smallest quantity of sodium be thrown into flame or other sources of light ,the bright yellow double line instantly appears.

钠特有的物理现象，然后通过 by 结构从·反正两方面补述得出此结论的实验过程，也就·是说，这个复合句通过连接词和形态变化把三·大层意思连接起来，先结果，后叙事，其语序①·②③几乎与汉语的表达习惯相反。因此，只有·如果把少量的钠投入火焰或其它光源中，·会立即出现一道金黄色的双线；当钠不存在时，光谱中这条线就消失了。由此我们知道，钠或钠的任何化合物所产生的光谱都带有一道金黄色的双线。

The spectral characteristics of the device were measured by an optical spectrum analyzer in a set-up with fiber coupling. A periodically vibrated resonance spectrum was observed with 10 dB contrast and 0.182 nm period. According to the experimental data and the theoretical formula of the ring resonator, transmission loss of 1.7 dB/cm in the ring resonator was obtained.

利用光谱仪对器件的传输特性进行了测量，观测到具有10 dB对比度，自由光谱范围0.182 nm周期性谐振现象，结合环形谐振腔的传输特性，得到环形腔具有较低的传输损耗1.7 dB/cm。
