The road through the forest one of those wagon-tracks that were being opened from the clearings of the settlers, and that wound along beneath trees of which those now seen in Kentucky are the unworthy survivors--oaks and walnuts, maples and elms, centuries old, gnarled, massive, drooping, majestic, through whose arches the sun hurled down only some solitary spear of gold, and over whose gray-mossed roots some cold brook crept in silence; with here and there billowy open spaces of wild rye, buffalo grass, and clover on which the light fell in sheets of radiance; with other spots so dim that for ages no shoot had sprung from the deep black mould; blown to and fro across this wagon-road, odours of ivy, pennyroyal and mint, mingled with the fragrance of the wild grape; flitting to and fro across it, as low as the violet-beds, as high as the sycamores, unnumbered kinds of birds, some of which like the paroquet are long since vanished.
通过这些车皮了正在从定居者的结算开首曲目森林一条道路,并沿下树木的伤口现在看见的,在肯塔基州是不值得的幸存者-橡树和胡桃,枫树和榆树,百年老,格纳尔德,大规模,下垂,庄严,通过投掷下来的拱门只有一些孤立的金矛的太阳,而超过其灰mossed基层一些冷布鲁克在沉默中悄悄地,与在这里和那里的野生黑麦,水牛汹涌的休憩用地草,三叶草上的光板下跌的光芒;与其他景点,非常昏暗,对于没有拍摄了从深黑模具;被炸来回穿越这车,路,常春藤气味,薄荷油,薄荷涌现年龄,夹杂着的野生葡萄香味,飞来飞去往返境而过,像紫床低,高的桑树,种鸟类的一间,其中一些像paroquet是早已消失了。

Patent, and then the blade-to-blade flow was computed by solving the two-dimensional steady Navier-Stokes equations, finally, overall performance and internal flowfield characterization were obtained and analyzed.2. As to radial matching between blade sections, preliminary investigations were developed from three aspects such as stall margin customizing technique, control technology of tip clearance flow, prediction model and control technology of corner separate.a On basis of reviewing on methods of achieving the goal of stall margin in design process of fan and axial-flow compressor, in conjunction of understandings on "Sweep/Dihedral", stall margin customizing technique was put forward; two-dimensional performance prediction method for stall margin customizing was developed, it can consider influences of radial stacking patterns of blade sections and axial distances between blade rows conveniently and rapidly.b A simple model for tip leakage mixing loss of unshrouded blades for compressible flow was presented.
二、叶片基元展向匹配方面,本研究从影响负荷最大化的叶身展向积迭注:原(来源:ABC论文35网www.abclunwen.com指掠弯是裕度定制的一部分,为方便论述,本文将此统一论述为裕度定制、叶尖间隙、叶片与端壁角区这三个最重要因素出发,探讨了各因素影响负荷最大化的机理,并由此给出了最大负荷设计过程中的技术措施和努力方向。1从掌控风扇/轴流压气机裕度方法回顾入手,探析了美国和俄罗斯裕度控制方法及相应特点,结合对&掠/弯&因素的认识提出了裕度定制技术:并开发了能够体现裕度定制思想的二维特性预估方法,可在二维层面下方便快捷地考虑以掠/弯为代表的叶片基元展向积迭以及叶片排间轴向间距带来的影响;2借鉴Denton关于不可压叶尖泄漏损失的理论分析,推导出适用于可压缩流动的叶尖泄漏掺混损失计算的基本关系式。
