同时共存的 meaning in English

coexistent

The characteristics of competition and coexistence of self - pumped phase conjugation ( sppc ) and mutually pumped phase conjugation ( mppc ) in the photorefractive ( pr ) crystal are studied , with the physical mechanism analyzed
本文研究了光折变晶体内自泵浦相位共轭( sppc )与互泵浦相位共轭( mppc )相互竞争、同时共存的特性，分析了其物理形成机制。
In order to improve the existing pr adaptive optical heterodyne detection system ( praohds ) , a new praohds is proposed based on sppc and mppc coexistence . the experimental study of the system is completed by equal amplitude ar + laser beams , poorly coherent equal amplitude solid - state laser beams and high speed amplitude - modulated solid - state laser beams through distorting media . experimental results indicate that the new system is applicable
为了改进现有的光折变自适应光外差探测系统( praohds ) ，本文利用sppc和mppc同时共存的特性，提出了一种新型的praohds ，并利用ar ~ +等幅激光、相干性较差的固体等幅激光以及固体高速振幅调制激光对新系统进行了畸变光束的自适应光外差探测实验研究，结果证明了新系统在实际应用中的可行性。
