| 8. | Why does combining the principle of relativity with the invariance of the speed of light lead one to conclude that no medium is required for light to propagate 为什么由相对论原理以及光速的不变性可以推导出光不需要介质即可传播? |
| 9. | The accuracy of 3 - d surface - shape measurement by phase - measuring profilometry ( pmp ) is greatly influenced , because the variation of environmental light leads to biggish error 摘要在运用相位测量剖面术( pmp )对物体进行三维面形测量时,由于测量现场环境光强变化而引入较大误差,严重影响测量精度。 |
| 10. | By the former experiment , we know that the fiber optic gas sensor with the pulse light of the blue light led can emit the steady fluorescence . so we can detect the density of oxygen through 技术方案上采用数字脉冲激励led蓝紫光源照射敏感元件获得稳定的荧光信号,再通过测量荧光寿命检测氧气浓度。 |
