Morphometrics has been pursued by graphical and computational means since the European Renaissance, drawing on core geometric principles first discovered in China and Classical Greece. Through the late 1800s, two distinct approaches to such analyses were pursued： a deformationist approach, epitomized by D＇Arcy Thompson＇s graphical trans-formation grids and the statistical approach popularized by Francis Galton, Karl Pearson, and Julian Huxley in which Cartesian spaces were employed to summarize patterns of variation in size and/or shape variables. Unification of these approaches was an off-stated goal throughout the 20th century, but proved elusive until the mid-1980s when David Kendall, Fred Bookstein, and colin Goodall proposed a radically new way of understanding form -- as the locations of configurations of landmarks on the surfaces of a nested series of hyperdimensional manifolds. Once this new mathematics of form was understood development of basic concepts, procedures, graphical tools, and statistical tests followed quickly such that the core of the long-hoped for synthesis took less than a decade to achieve. The result-- geometric morphometrics -- continues to develop into an ever-more extensive toolkit that can be used by researchers to describe and understand a wide range of problems involving the characterization of morphological similarities and differences in all of their many and varied contexts. In particular, the new approaches involving the direct analysis of image pixels and new tools such as machine learning and artificial intelligence are set to reinvigorate （and possibly to revolutionize） the field once again.

可控硅阀有完善的均压电路.因此,按电压比例增加串接级数并不增加各级正常工作电压应力.但是,扩充到800 kV时,为了避免电晕放电和达到经济上的低廉,但又有安全的阀厅空气间隙,必须对电极表面几何形状进行特殊优化.寄生电容上储存的能量随电压的平方增加,这在阀电抗器的设计中对于接通di/dt的控制有重要影响.阀厅的绝缘故障就更为严重,需要特别注意对陡前波电压的控制.变流器阀的大尺寸将影响阀的机械设计,尤其是对地震活跃地区的应用.即使装备很好的实验室,800 kV阀的试验要求仍将是一个挑战.本文考虑了以上问题,并讨论了主要电路的拓扑结构对这些问题的影响.

不许乘轮渡,不许竟逐,里程不能超过480km,最长时限24小时——这是法拉利试驾车规定那么,这一天里我将如何与拥有565kW澎湃动力的法拉利F12TDF跑车共处呢24小时,480公里。无论我们想保持多快和多远,它都能如你所愿——这就是法拉利F 12TDF跑车!究竟应该如何使用它呢？摆脱限制循路而行,我们不必穿越隧道。一个简洁的想法就是把它放上拖车,运到苏格兰高地。但是那样一来将会是忙乱的。而在它的车轮之上,十分钟就能到达我们想去的地方。
