Negative refraction was a special kind of refraction phenomenon, in which the refracted light and the incident light were on the same side of the normal. The application examples in real life were as follows: In terms of optical imaging, negative index lenses and their imaging systems could be designed using negative index materials with special imaging performance or smaller aberrations than traditional lenses. Since the energy flow direction of electromagnetic waves was opposite to the phase velocity direction when they traveled in a negative refraction medium, the parallel plate lens constructed using this medium could magnify the evanescent wave, thereby breaking through the refraction limit to perform sub-wave imaging on nearby objects, greatly improving the imaging resolution of the lens. In the field of nanotechnology, nanostructured materials, for example, had demonstrated negative refraction properties, which was an important step in the creation of photon circuits. A newly invented nanostructured material could reflect light back no matter what angle it was shot at. Although this phenomenon had not been observed in nature, artificial manufacturing had made it a reality and applied it to the development of related technologies. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

In Chinese, there were some words that had the same meaning when two words were read in reverse, such as " mutual " and " mutual ", both of which meant that they treated each other.

His father squeezed into the train to the provincial capital to visit his son, who had been studying at university for almost a year. He did not bring any luggage and only brought 20 hard-boiled eggs. His father was wearing his clothes inside out, which attracted the curious gazes of the people in the car. When he was handed a cigarette, he refused because he was worried that there was knockout powder in the cigarette. After all, there was 500 yuan in his pocket for his son's living expenses. When asked why he was wearing his clothes inside out, his father was initially unwilling to answer.

His son had excellent grades from elementary school to high school and was admitted to a key university in the provincial capital. In the past, his father had used this method when he went to visit his son in the county town. This dress had been bought for nearly four years, but it was still very new because it was often worn inside out. This novel reflected the deep and selfless love of a father for his son. He would rather suffer the embarrassing gaze than protect his son's face. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
