使循环

Bumer of this type is favorable for primary air-coal flow ignition and flame stability, as well as low Nox emissions. Flue gas re-circulation is employed to prevent furnace slagging and opposed-fired burner arrangement is capable of reducing residual swirl of furnace exit flue gas.

该炉燃烧器有利于煤粉气流的着火和火焰稳定；低Nox燃烧，有利于环保；与烟气再循环配合有利于防止炉膛结焦；前后墙布置切圆燃烧方式减少了炉膛出口气流的残余旋转，使水平烟道烟气流速分布更趋均匀。

The appropriate assembly temperature is related to mechanics properties of material and operating temperature, so reiterative computations are necessary to find an appropriate assembly temperature by the method that makes the maximal tensile stress smallest under conditions that the maximal compressive stress is less than the compressive yield point of material.

安装温度的选择与材料的力学性能及零件的工作温度紧密相关，因此选择合适的安装温度需要反复计算，其方法是在保证循环中的最大压缩应力小于材料压缩屈服点的条件下，使最大拉应力最小。

Under this model,"by-product" or "rejectamenta" of one produces process may be the raw material of another process. So that the resources of the entire industrial system comes to be a closed-loop circle. By this way, we can well protect the environment while enhancing the economic welfare.

所谓工业共生，在某种程度上可简单地理解为就是企业间副产品的交换，即一组企业寻求利用彼此的副产品，而不是将其作为废物处理掉：这样使整个工业体系转变成各种资源循环流动的闭环系统，做到经济、社会、环境的和谐发展。

The new system settled many problems in the traditional system controlled by relay and contact device,improved the anti—disturbance ability of feeding coal system,reduced the failure rate.

新系统解决了传统的继电器接触器控制的诸多问题，提高了输煤系统的抗干扰能力，降低了故障率，使运行安全可靠，实现了经济效益和社会效益的良好循环。

The waste motor remanufacture can actually retain the added value of the waste motor,which could be used in the next cycle process.

废旧电机再制造，实际上是一个充分保留废旧电机中的附加值，使其进入下一步循环的过程。

The limiting cycle times represented in the model become independent of each other.Thus,the process can be transferred into a renewal process and a stochastic optimization formulation is developed based on renewal process theory.

该方法使模型的限定循环时间变为相互独立的，从而可将原过程转化为更新过程，并根据更新过程原理建立了优化该过程的期望值模型。

This "Old Time" thinking can make you miss out on one of the most important events in your life – the opportunity to own your own home and get out of the vicious renter's cycle.

这个"旧时代"的思想可以使您失去最重大的事件之一，你一生有机会拥有自己的家园和租房走出恶性的循环。

And have improvement microcirculation , resist blood platelet aggregation and thrombopoiesis, can make blood viscosity come down , improve blood circulation.

还具有改善微循环、抗血小板的聚集和血栓形成，并能使血液粘度下降，改善血液循环。

As a new subject, many aspects of ecosystem health are in the seedtime.

工业文明以来，人类以前所未有的规模和强度影响环境，改变甚至破坏自然生态系统，致使生态系统的健康受到越来越大的损害，引发了一系列的全球性环境问题，由此危及到人类自身的生存，这促使人们认识到维护与保持生态系统健康，促进生态系统良性循环的重要性，使生态系统健康成为当今学术界重点关注的研究领域之一。

Studies suggest that when chewing repeatedly Masseter contraction, relaxation can promote brain blood circulation, chewing mouth movements so that a variety of exciting sensory organ to promote the intellectual development.

研究认为，咀嚼时咬肌反复收缩、弛张可以促进大脑血液循环，咀嚼运动使口腔各种感觉器官兴奋，促进智力发育。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
