| 1. | The grating spectrograph is built in two designs .
光栅摄谱仪有两种类型。 |
| 2. | The grating are made of rods or wire .
光栅由金属或丝制造。 |
| 3. | The need for larger and better gratings became apparent .
对更大、更好的光栅的需求变得突出起来。 |
| 4. | The light is resolved by prisms, gratings, or by an interferometer .
光线用棱镜、光栅或干涉仪分解。 |
| 5. | In order to get a narrow angular spread, we need to use the whole grating .
为了得到较窄的角展度，我们必须利用整个光栅。 |
| 6. | Grating spectrometers, used over the ranges from soft x-rays to the far infrared, have enjoyed continued interest .
使用范围从软x射线到远红外线的光栅光谱仪继续受到注意。 |
| 7. | the spectrograph uses a concave diffraction grating that provides a wavelength dispersion of 4. 2a°/mm in the first order.
光谱仪用了一块凹面衍射光栅，第一级光谱的色散度为42埃毫米。 |
| 8. | Amazingly enough, a beam of electrons had thus been diffracted in a manner completely analogous to a light wave bouncing off a reflection grating .
一束电子波衍射的方式，同光波从一个反射光栅上弹回的方式完全类似，这真是不可思议。 |
| 9. | proof of distributed feedback was the tuning of the laser wavelength over 130°a by changing the grating period, and the absence of shift in wavelength with increasing excitation current.
存在分布反馈的证据是，改变光栅周期可使激光波长在130A范围内变化以及波长不随激发电流的增大而移动。 |
