real area meaning in Chinese
实际面积
Examples
- It holds that the real area protected by copyright is the exclusive one occupied by private entities while the unprotected is public domain
它认为著作权保护的真正领域是被私人所占有的专有领域，不被保护的则是公共领域。 - This problem has vide applications in real areas , such as the design of water and electricity supply networks , and communication networks , etc . at the same time , the problem is also closely related with some classical combinatorial optimization problems , including the steiner problem and the travelling salesman problem , which are well - known . so , it is of great importance to study it
所谓欧几里德2 -连通steiner网络问题，就是对于给定的平面点集p ，确定它的长度最小的2 -连通steiner网络，该问题与组合最优化中著名的steiner问题和旅行售货员问题有关，同时在水、电供应网络和通讯网络等设计中也有非常广泛的应用，所以对该问题的研究具有重要的意义。 - The ultrasonic dynamic contact of bolt - clamped transducer and rigid plane are modeled using hertzian contact theory , and the analyzing results reveal that the nodal plane of the bolt - clamped transducer is levitated in normal direction by the ultrasonic dynamic contact action , and the real area of contact of bolt - clamped transducer and rigid plane decreases in the same time
首先利用赫兹接触理论建立了夹心式换能器和刚性平面的超声动态接触模型。通过对模型进行分析、求解表明,在纵向超声频率动态接触作用下,换能器节面位置产生了上浮,换能器端面与刚性平面的动态真实接触面积比静态时减少了。
