The calculation results of direct coupling and sequential method and test results are compared , it is proved that direct coupling is more advantageous and the calculation results are more accuracy than that of sequential method 对直接耦合法和顺序耦合法的计算结果与实验结果进行比较,证明直接耦合法解决非线性耦合问题更具有优势,得到的结果更准确。
Abstract : the structural and thermal stress distribution of the containerwith spiral cooling groove is calculated using direct coupled - field analysis of fea . the cooling and nocooling effects and the preliminary result of the analysis are discussed here 文摘:通过对具有螺旋线型冷却槽的挤压筒结构应力和热应力计算及冷却效应的对比分析,给出了对实际设计、工艺过程有重要意义的初步结论。
But how to eliminate the influence of direct coupling signal is the hardest problem when using the induction logging tool and array induction logging tool . based on induction logging , phase induction logging is studied to avoid the above problem , which makes the apparatus ’ s research and manufacturing easier 因此,在感应测井基础上提出了测量场的相对特性的阵列相位感应测井,避开了在感应测井中非常棘手的直耦对消问题,大大降低了仪器研发的难度。
Unlike conventional open surgery , where operative manoeuvres are predominantly intuitive , surgeons practicing mis have to operate and assess organ structures on a television monitor with its flat two - dimensional image rather than relying on direct vision and the important sensation of touch . not only are movements restricted by the keyhole access , they also become paradoxical in nature since the normal direct coupling of hand and eye no longer applies 要用微形摄影机观察身体内的状况,手术的进行只靠投影在萤幕屏上的二维影像去判断,加上动作受制于微细的切口,又没有直接的手眼的协调,令手术的进行加倍困难。
The principle advantages of vcsels over conventional edge - emitting lasers lie in ultralow threshold current , small far - field divergent angle , high modulation frequency , potential for wafer level testing and the ease for single longitudinal mode operation and two - dimension integration . as a result they show considerable promise for applications such as optical fiber communication , parallel optical interconnects , optical information processing and neural networks , etc . a direct coupling theoretical model in quasi - three - dimension for the gain - wave guide vertical - cavity surface - emitting lasers has been created in this paper 它与传统的边发射激光器相比具有更优越的特性,例如,具有极低的阈值、较小的远场发散角、调制频率高、易实现单纵模工作和二维集成,无须解理封装即可进行在片测试等,所以,它被广泛应用于光纤通讯、并行光互联、光信息处理、光神经网络等领域。
