Using finite-element method the effects of long objects, such as cage, train and metal pit prop, on electromagnetic wave cutoff frequency is researched systematically in regular tunnels, and it is shown that the long metal objects lower TE wave cutoff frequency and raise TM wave cutoff frequency.

利用有限元方法系统地研究了机车、罐笼、金属支护立柱等长列金属物体对井下规则隧道中电磁波截止频率的影响，可知长列金属物体的存在使TE波模截止频率降低，而使TM波模截止频率升高。

There is no essential difference between the two, as the pool of metal around the hole surrounded by molten metal gravity and surface tension have to make holes to bridge the trend, while the metal vapor is generated by a continuous attempt to maintain the existence of holes.

从机理上看，这两种焊接方法的前提都是焊接时存在小孔，两者没有本质的区别，小孔周围为熔池金属所包围，熔化金属的重力及表面张力有使小孔弥合的趋势，而连续产生的金属蒸气则力图维持小孔的存在。

The recent progresses in these fields were summarized in this paper. It focuses on the activation and oxidation on a series of hydrocarbons (from CH4 to these hydrocarbons with six carbons). The catalysts and oxidants reported here include organic metal compounds and inorganic compounds (such as molecular sieves, metal clusters, metal oxidates and so on).

本文总结了近几年在碳氢化合物的活化及氧化领域的一些新进展，涉及的底物包括从甲烷到碳原子数等于6的烃类，而催化剂及氧化剂包括有机金属化合物和无机化合物（如分子筛催化剂、金属团簇和金属氧化物等）。

One is the wire-wound spring into cylindrical shape or rolling circle equipment into ready-to-wear pressureof ship'spennant bookbiding shape metal ring, having been set before even having the mouth perforatig, metal ring by hand or machine mode into the holes in the even of a commentary.

一种是将金属丝绕卷成圆柱弹簧形状或用卷丝圈设备卷成可直接穿压的长条形状金属环，装订时先在被订连本册的订口上打孔，再将金属环用手工或机器方式穿入孔眼内订连成册。

Thermostats in the top of the radiator contained a spring-loaded valve, the spring being made of two dissimilar metals (bi-metallic, just like the ones in your home) and when the temperature got to 180o, the metals would expand, open up the valve, and permit the water pump to start pumping the water though the radiator where the onrushing air due to the vehicle's motion would cool the water and keep its temperate at 180o.

恒温器，在上方的散热器上载有弹簧加载阀，春天正在取得两个异种金属（双金属，就像那些在你家）和当温度到了180o ，金属将扩大，开拓阀门，并允许水泵开始抽水的水，虽然散热器的地方onrushing空气由於车辆的议案，将冷却水，并确保其在温带
