WonTen Oxy-Hydrogen generators separate clean, soft water (H2O) into hydrogen and oxygen gases using a small amount of electric power via our patented process and recombine them into an efficient mixed-gas fuel. With the right combination of oxygen and hydrogen gases, our generators avoid an oxidizing flame, which means there are no carbon emissions, no greenhouse gases, no toxins and no pollutants!

氢氧焰能源设备运用少许电力即可将水转换为氢与氧，经混合后成为高效率的燃料，免除运送与储存问题，安全、无毒、无污染，并解决了替代能源所面临的高成本问题，只要有水就有能源，随时可再生，环保、节能，经济效益庞大且技术应用广泛！

The hydrogen vent line is being reattached to the external fuel tank. The vent line carries gaseous hydrogen away from the launch pad to the flare stack, where the vented hydrogen is burned off.

北京时间3月13日消息，据国外媒体报道，美国宇航局已开始在线直播有关国际空间站外景象的视频，但欣赏这种直播是有条件的，网民必须等到空间站工作人员睡觉或者下班的时候。

According to a report in Battery Bimonthly, there is an annual market demand of 40,000—50,000 tons of hydrogen storage alloy powder in the world, and the annual demand of hydrogen storage alloy for common Ni-MH chemical battery in China is around 8,000 tons, however the annual output is less than 5,000 tons. At present, demands of hydrogen alloys for Ni-MH chemical batteries are increasing by over 30% in each year and there is still a big vacuum in the market.

据《电池快讯》报道：全世界每年约需贮氢合金粉40000—50000吨，我国普通镍氢电池用贮氢合金每年需求量约8000吨，国内实际年产量不足5000吨，镍氢电池用贮氢合金目前国内需求量每年以30%以上的速度递增，市场需求缺口很大。

On the other hand, steam can be used to restrain the side reaction such as hydrogen transfer reaction so as to increase the yield of light olefins by diluting the concentration of the reactant. In addition, minor steam can react with the feed hydrocarbon resulting in the decrease of coke and the formation of active hydrogen without the increase of hydrogen gas and light saturates that is not desirable.

另一方面，水蒸气不仅仅具有降低烃分压的作用，抑制了氢转移反应等副反应，对于低碳烯烃的产率有好的影响，而且在反应过程中，少量参与了反应，与烃类发生了水煤气反应，生成了活泼氢，不仅降低了焦碳的产率，并且没有提高氢气、低碳烷烃等不希望得到的产物。
