双极的

Because of the rapid development of the wireless communication technology, the design and research of the integrated circuits in the related field has gained more and more attention in recent years. And with the advance of the IC process technology, the cutoff frequency of MOS devices can reach several giga herz or more. It is a trend that CMOS process will replace the III-V compound process such as gallium arsenide or silicon bipolar process which were dominant in the fields of radio frequency and microwave.

近年来，由于无线通信技术的飞速发展，相关领域的集成电路的设计研究也受到越来越多的关注；同时由于工艺技术的不断进步，MOS器件的特征频率也可以达到几个GHz或更高的水平，原来在射频、微波领域占主导地位的三五族化合物半导体工艺如砷化镓及硅双极型工艺也有逐渐被CMOS工艺所取代的趋势。

The self-centering mechanism design of bipolar endoprosthesis has advocated the use of offset centers of rotation between the inner and outer joint bearing surfaces to generate a self-centering moment on loading to prevent impingement of polyethylene rim and stem neck or cup fixed at wrong place. The design was used popularly, but the function of self-centering mechanism was discussed in very few papers. Three bipolar endoprosthesis were evaluated: UNIQHIP system, UHR system, and AML system.

双极式半人工髋关节的离心复位机构，是利用髋臼外帽的球心与股小球的球心两者在不同点，来防止发生髋臼外帽固定於髋臼中某角度卡住不动，而使股骨柄颈部固定磨损超高分子聚乙烯内衬之一边缘，进而加速超高分子聚乙烯内衬之磨耗，造成骨溶蚀与人工髋关节的松脱。
