| 1. | Questions about norms and spectra are likely to be recalcitrant .
有关范数和谱的问题多半是难解的。 |
| 2. | The concept of a continuous spectrum is obviously unmanageable graphically .
连续谱的概念显然用图形无法表达。 |
| 3. | Several other peaks also appear as major contributors to the spectrum .
另一些峰也作为这个谱的主要组成而出现。 |
| 4. | Several different names have emerged to characterize different parts of the spectrum .
几个不同的名称用来表示电磁波谱的不同部分。 |
| 5. | Ethylene and trans-dichloroethylene are both inactive in the infra-red in this region .
乙烯和反式二氯乙烯在红外光谱的这个区域都无活性。 |
| 6. | Ethylene and trans-dichloroethylene are both inactive in the infrared in this region .
乙烯和反式二氯乙烯在红外光谱的这个区域不出现吸收峰。 |
| 7. | The shape of the electron spectrum in beta decay is not dominated by properties of the matrix element .
衰变的电子谱的形状不取决于矩阵元的性质。 |
| 8. | All intensity measurements using photometric units include a spectral bias (spectral response of the human eye) .
运用光度计装量进行辐射强度测量都应包括一个光谱的偏倚（人眼对光谱的敏感度）。 |
| 9. | After processing, the sensitometrically exposed step wedge is read on a densitometer and the data is plotted .
加工完毕后，即用密度计对试验胶上复制的阶梯级谱的密度进行测定，然后用测得的数据作图。 |
