场衰减 meaning in Chinese

field reduction

The decay of the external scalar - field of a black hole is studied in the third chapter , i . e . , the physical mechanism of the decay of neutral scalar - field in the gravitational collapse , and the physical mechanism of the decay of charged massive scalar - field in the gravitational collapse
第三章主要研究无质量标量场在黑洞外部的衰减，即无质量中性场在引力塌缩中随时间衰减的物理机制和无质量荷电标量场衰减的物理机制。
The second chapter is about model experiment study , it introduces purpose , scheme , equipment and experiment contents having copperplate and copper ball as object by comparability rule experimenting plenty of physical models , deals with experiment data and makes second field attenuation voltage curves first field isoline both single aperture and mutli - aperture in different situation . in the end , it obtains best depth of multi - aperture source
利用相似性准则进行大量的物理模拟实验，实验观测中以铜板和铜球作为目标体，详细介绍了模拟实验研究的目的、方案、使用设备以及实验内容，并对实验数据进行了处理分析，作出了不同模拟条件下单、多孔径的二次场衰减电压曲线和一次场等值线图，找出多孔径作发射源的探测最佳深度。
