The image was captured using four narrow-band filters that have been tuned to see hydrogen as well as ionized helium, sulfur and oxygen.
获取该图像时使用了四个窄带滤光片，它们都被调谐到可见氢、电离氦、硫和氧。NASA's Interstellar Boundary Explorer satellite, or IBEX, discovered the narrow ribbon, which completes nearly a full circle across the sky.
美国航空及太空总署的星际边缘探测卫星（也叫IBEX）发现了这条窄带，它近乎一个完整的圆形。The preprocessor can extract clock information from NRZ data stream, which consists of a delay cell, a multiplier and a narrow-band filter.
预处理器主要有延迟单元、乘法器和窄带滤波电路构成，可以从NRZ数据中得到时钟信号。Such a strip equipped with a buckle or similar fastener for binding or securing objects.
吊带：带有扣或相似的扣拴物以拴住或固定住物体的这种窄带。The mosaic includes image data taken through a narrow filter that transmits only the red light of hydrogen atoms.
这张拼贴图中所含的图片数据是通过窄带滤波器得到的，它只会传播氢原子发出的红光。Narrow-band density measurement is mainly used for measurement of dot, overprint, deposit and inks.
窄带密度丈量主给用于丈量网点增大、叠印、不朱层厚度及油不朱强度。Feedback laser which generates narrow band light source for the Optical fiber gas sensor is too expensive to be used in engineering.
但由于产生窄带光源的反馈式激光器造价很高，因此没能够得到实际应用。Without changing the period size, the frequency bandgap is varied when the length of the stretching strip is adjusted.
在不改变周期的情况下，通过调整伸长窄带长度可以改变带隙特性频率。Result characteristics of wave diagram, voice broad band spectrum, as well as the voice narrow band spectrum at the edit points were found.
结果找到剪辑点痕迹特征在时域波形图、宽带语谱图、窄带语谱图上的反映。
