即当作用于翻板上的物料产生的力矩大于重锤摇杆产生的力矩时，阀板打开卸灰，一旦积灰卸去后，重锤与摇杆产生的力矩使阀板迅速关闭，实现锁气是由于本阀采用的是双层结构，因而使管道上阀板始终有一个是关闭状态，可使卸灰与锁气同时达到目的。

Ma Ying also pointed out that although oil prices have fallen over the highest point, but Air China will be difficult to enjoy the benefits of lower oil prices, mainly due to the original Air China by the international price of oil procurement Make up for the decline in hedging losses (of the decline in procurement costs higher than the loss of security units) in order to benefit from a decline in the price of crude oil, but because of the signing of contracts, including the other party has the right to determine in advance in accordance with the agreed price of the company to sell a certain number of cycles of Fuel, so the amount of losses may be higher than the drop in oil prices brought about by the decline in costs.

马英九还指出，虽然油价已经下跌了最高点，但航空公司中国将难以享受油价下跌带来的好处，主要是由于国际石油价格在原中国航空采购弥补在对冲损失（在采购成本比更高的安全部队损失下降）下降，以受益于原油价格下跌，但由于所签订的合同，其中包括对方已按照事先确定的权利，与公司商定的价格出售了一定数量的燃料循环，所以损失的金额可能低于石油价格下降所增加的成本下降带来的。

The experimental results show that:(1) for ideal spheres, the attenuation coefficient of velocity is constant, the air drag coefficient is slightly affected by the initial velocity and is a linear function of initial velocity, and (2) for real fragments formed by a warhead, the flight performances are different from ideal spheres, the air drag coefficient is affected by the flight velocity and is a linear function of flight velocity.

实验结果表明：(1)对于理想球形钨合金破片，在同一初始速度条件下，衰减系数为常数，空气阻力系数与初始速度有关，两者成线性关系；(2)对于经历爆轰驱动的球形钨合金破片，由于有轻微的质量损失和变形，速度衰减规律与理想球形钨合金破片有明显的区别，空气阻力系数与飞行速度有关，两者成线性关系。

But for the mesothermal and low temperature power generation by waste heat introduced distributing hot air,the power generated by unit heat enery is then increased greatly——by distributing the hot air entered the preheater,the ratio of gas and solid is decreased,the heat efficiency of the pr.

采用热气体分流的中低温余热发电技术，即：将入预热器系统的热气体予以分流，降低了预热器内气固比，提高了预热器系统热效率；同时使原预热器出口烟气中的低级热能转移至温度较高的烟气中，热能得到升级，可大幅度提高其余热发电量。

There is granular material on the top and the edge of the spikes induced by nanosecond laser pulses in air atmosphere, which is formed by solidification of the droplets. The micro-structures formed in air are different from the slender whiskerlike structures created by excimer laser and also different from the conical microstructures with dendritic nanostructures formed under femtosecond laser irradiation.

The effect of the tool composition on the friction and wear behavior was investigated,and the morphologies of the rake face and rear face of the tool cutting the steel in air and nitrogen were observed on a scanning electron microscope. It was found that the Al_2O_3/TiB_2 tool was dominated by adhesive and abrasive wear in low speed dry cutting; while in high speed dry cutting,the tool was characterized by oxidation wear. An oxide layer of TiO_2 was formed by way of the oxidation of the reinforcing agent TiB_2 at a very much high cutting temperature, which contributed to greatly reducing the friction coefficient and increasing the antiwear life of the tool.Such a friction-reducing and antiwear behavior of the oxide layer was enhanced with increasing content of TiB_2 in the tool composite. However,the tool showed a relatively poorer wear resistance in N_2 than in air, because N_2 acted to retard the oxidation of the TiB_2 and the formation of the oxide layer on the tool rake face.

结果表明：低速干切削时，Al2O3/TiB2陶瓷刀具的磨损机制主要表现为粘着磨损和磨料磨损；而在高速干切削时，刀具的磨损机制主要表现为氧化磨损，刀具表面经由氧化反应生成具有润滑作用的反应膜而起到固体润滑作用，从而使刀具的耐磨性能提高，随着TiB2含量和切削速度的增加，反应膜的减摩抗磨作用增强；而在切削区通入氮气时，由于刀具表面氧化膜形成受阻，刀具的抗磨能力有所降低。
