STRUCTURE: Titanium and composites used extensively, with particular emphasis on corrosion resistance; fully articulated three-blade coaxial contrarotatmg rotors have all-composites blades with carbon fibre and glass fibre main spars, pockets (13 per blade) of Kevlar-type material, and filler similar to Nomex; blades have non-symmetrical aerofoil section; each has ground-adjustable tab; each lower blade carries adjustable vibration damper, comprising two dependent weights, on root section, with further vibration dampers in fuselage; tip light on each upper blade; blades fold manually outboard of all control mechanisms, to folded width within track of main landing gear; rotor hub is 50% titaniuin/50% steel; rotor brake standard; all-metal fuselage; composites tailcone; fixed incidence tailplane, elevators, fins and rudders have aluminium alloy structure, composites skins; fins toe inward approximately 25°; fixed leading-edge slat on each fin prevents airflow over fin stalling in crosswinds or at high yaw angles.

结构：钛和复合材料广泛使用，耐腐蚀性能与特别强调，充分阐明三叶片转子同轴contrarotatmg有碳纤维和玻璃纤维的主要棒材全复合材料桨叶，口袋（每刀片13）凯夫拉型材料，类似的Nomex纤维填料；叶片非对称机翼部分，每有地面可调选项卡，每降低叶片振动阻尼器进行调节，包括两部分依赖重根，在机身进一步减振装置；小费每个刀片上轻；刀片倍手动舷外所有控制机制，折叠宽度内的主起落架的轨道；转子中心为50％titaniuin/50％钢；转子制动标准；全金属机身，复合材料tailcone，固定发生机尾，电梯，蛙鞋和方向舵的铝合金结构，复合材料的皮肤；鳍鳍在每个脚趾向内约25 °；固定领先的板式翅片防止了侧风或气流停滞在高偏航角度。

Later, a British ambassador to North Korea with diplomats from the Western aesthetic point of view of this flag-Tai Chi nosy made changes and removed the titillation of four downs, and the remaining four downs oblique symmetric stretching, the entire rectangular flag design submissions, yin and yang fish patterns into two colors red and blue, so now we can see eunuchs Korean flag.

后来，一名英国驻朝鲜的使节用西方美学的角度为这面太极八卦旗做了修改，去掉了八卦中的四卦，把剩下的四卦斜向对称拉伸，使整个国旗图案呈长方形，把阴阳鱼图案改为红蓝两色，这样才有了现在我们看到的韩国太监旗。

However, proving axisymmetry for the Onsager model is still very difficult, at least for two reasons: The first is that we lack methods for proving axisymmetry, even though there are method for proving radial symmetry or translation invariance.

但是，证明了Onsager模型轴对称仍然是非常困难的，至少有两个原因：第一，我们缺乏证明轴对称的方法，即使是证明辐射对称或平移不变性的方法。

In this paper, the influence of rotor-skewing on the machine performance, such as the unbalanced radial force, cogging torque and back EMF, is analyzed, with two different prototypes being comparatively studied.

分析了转子斜极对其不对称径向力、齿槽定位转矩和反电势等性能的影响，并用两种不同结构的电机进行对比研究。

There are lots of courses for those problems and some can be explained with the economic theory. For example, the increasing depletion of marine fisheries resources is resulted from the unclarity of ownership to fishery resources, which produces the dissension between different regions and between the port developers and the government. And there are also conflict between the current interests and long-term interests. In addition, the contamination of marine environment is from the information asymmetry.

产生上述问题的根源有很多，有些问题可以从经济学理论中得到解释，如海洋渔业资源的日渐枯竭，根源在于渔业资源的产权归属不明晰，而港口资源的价值低估在于港口开发商与政府、政府当期利益与远期利益、不同区域之间等三个博弈"瓶颈"，海洋生态环境的破坏则是因为两方面的信息不对称。
