内旋

is brought out in this thesis. Firstly, absolute velocity of galaxy moving in cosmic is 0.6 times of light velocity in vaccum; secondly, the sun kernel may has high speed of self-spinningabout thirdly, inner pressure of the sun is not so much, and its stability is the cause of its high speed of self-spinning.

并由此我们得到了以下的结论：1、银河系在宇宙中的绝对速度为真空中光速的0.6倍；2、太阳内核可能有高速的自旋 3、太阳的内压强不是很大的，它的稳定也是由于自身的高速自旋的原因。

Through the cold-state and simulation result, the special flow field of the burner can be obtained. It would be adjusting well when primary air nozzle adopting this form of inner-straight and outer-swirling. Inner straight can assure enough distance of jet, outer-swirling can entrain enough high temperature flue gas to burst into flame easily.

The invention relates to a nut (10) comprising an outer body (16) with an axial passage (22), an inner body which can be movably placed in the passage along an axial direction and which is divided along said axial direction into at least two jaws (18, 20), each jaw bearing an inner thread segment (24) on its radial inner surface, first guiding means (26) located on the outer body, as well as second guiding means (30) located on the jaws and co-operating with the first guiding means so that the jaws are radially displaced towards the exterior when the outer body is displaced in the unscrewing direction relatively to the inner body et radially displaced towards the inside when the outer body is displaced in the screwing direction relatively to the inner body.

本发明涉及一种螺母(10)，它包括：一个带轴向通孔(22)的外体(16)；一个内体，位于通孔(22)中，可沿轴向移动，并且沿所述的轴向方向至少分成两个滑块(18、20)，它们各自在其径向的内表面上具有内螺纹部分(24)。在外体上有第一导向装置(26)，同样滑块上有第二导向装置(30)，第二导向装置与第一导向装置共同起作用，所以，当外体相对于内体沿旋松方向作相对滑移时，滑块径向地向外滑移，并且，如果外体相对于内体沿拧紧的方向滑移，则滑块径向地向内滑移。

It takes a cylindrical NdFeB multipole permanent magnet composed of several neighboring tegular magnets magnetized anisotropically along radial direction as exterior actuator, and a magnet with the same structure embedded inside the robot body as the inner actuator. The robot screws forward inside pipe under the action between spiral rib on the exterior surface of robot body and fluid dynamic pressure when robot rotates by magnetic torque, which is generated by magneto-mechanical coupling from rotating exterior actuator to inner one.

While traditional farming experiences and preliminary experiments on minimum tillage showed a preference of alternating furrow slice inverting and deep loosening without inverting in some of the agricultural regions in China, the development of a PTO driven furrow slice inverting rotary plow as primary tillage implement inplace of the conventional moldboard plow was justified from the standpoint of less tractor traffic, less soil compaction, less energy consumption, sowing in time etc.
