In the face of such concerns and quasi-religious ethical issues about creating artificial life many synthetic biologists are making a big effort to explain their research to the public and engage with critics.

向公众解释合成生物学面对此种担忧--以及有关创造人造生命的准宗教伦理问题--许多合成生物学家正做出巨大努力，向公众解释自己的研究工作，并与批评者接触。

The force transmission, due to the crane trolley wheel pressure, from rail to bias-rail box girder belongs to the nonlinear contact. There is a coupling relationship between the deformation of contact area and the stress distribution.

小车轮压作用下，轨道与偏轨箱形梁之间力的传递属于接触非线性问题，接触面间的变形和应力分布存在相互耦合的关系。

With the development arise some problems of the wheel/rail performance, the requirement of the train traction for the adhesion of wheel/rail will become more and more strict, and rail corrugation of wheel/rail, rolling contact fatigue and derailment will become more and more serious. The solution to the problems will have direct effects on the railway development.

当前世界铁路正朝着高速和重载的方向发展，随之而来的是列车牵引对轮轨粘着的要求越来越高，而轮轨的波浪形磨耗、滚动接触疲劳、脱轨等轮轨关系问题越来越严重，其解决与否直接影响到铁路的快速发展。

The development tendency of the railway construction in the world today is serving high speed trains and csirrying heavy load. With the development arise some problems of the wheel/rail performance, the requirement of the train traction for the adhesion of wheel/rail will become more and more strict, and rail corrugation of wheel/rail, rolling contact fatigue and derailment will become more and more serious. The solution to the problems will have direct effects on the railway development.

The characteristic of this series leveler iS that it has adopted two national patent technologies:group driving plate levelling machine ZL200420001176.0 and axial decelerating motor leveler ZL200520007514.6.Each top roll is driven by a set of decelerating motor.and every two lower rolls are driven by a set of dynamic system,so that the line speed of each roll iS consistent with sheet metal speed of the contacting part,and it has solved the problems existing in traditional transmission system,such as friction between sheet metal and roll surface.and mechanical interference problem in the system And the working roll adopts spherical roller bearings which have little friction resistance.so this series leveler has such advantages as high levelIing quality,Iittle noise,low energy consumption and environmental protection.compared with traditional levelers.

该系列矫平机的特色之处在于：采用分组驱动板材矫正机(ZL200420001176.0)和一种轴装式减速电机矫平机(ZL200520007514.6)两种国家专利技术，每根上辊由一套减速电机驱动，每两根下辊由一套动力系统驱动，从而使各辊的线速度与所接触部位的板料速度相一致，消除了传统传动系统存在的板料与辊面之间的摩擦和传动系统内部的机械干涉问题，同时由于工作辊的轴承均采用轧机用调心辊子轴承，摩擦阻力小，因此，该系列矫平机与传统矫平机相比，矫平质量高、噪音小、能耗低、节能环保。

The plan of using magnetic bearing in rotating box high speed centrifugal separator of nitrogen and oxygen was proposed.

经过全面分析和充分论证，解决上述问题可行的措施还是采用非接触

Structural improvements in reducing the pump parts with sand contact, such as probability and the probability scaling has played a certain effect, but the pump body material at all times, everywhere in the wear and corrosion can not simply eliminate the problem.

结构的改进在减少输油泵部件与砂粒接触几率和结垢几率等方面起到了一定的效果，但是泵体材料无时不在、无处不在的磨损和腐蚀问题还不能根本消除。
