| 9. | The diffraction formula and statistical law of optical fields are used to get the cross - correlation function of intensities of laser speckles of the moved diffuse object
该方法利用光传播的菲涅尔衍射公式和光场的统计规律，给出散斑场光强在散射体位移前后的高斯光束相关函数的表达式。 |
| 10. | A third theory embraces the idea that a minute acceleration exists in the velocity of light , which might result in the appearance that the probes are slowing down : if light travels faster , telemetry signals arrive faster , and the craft seem to be closer
第三种理论则认为光速有著很小的加速度，导致太空探测器的减速效应：假如光传播得较快，遥测讯号会较早抵达，使得太空船看来似乎离我们较近。 |
