Where petrol and diesel-powered vehicles now account for almost all those on the road, by 2050 they would be in a minority, with some combination of battery, hydrogen and advanced biofuel used in the rest.

今天，马路上跑的几乎全是以汽油和柴油为动力燃料的汽车；而到2050年，它们将只占少数，其余车辆都将使用电池、氢和高级生物燃料所构成的某种混合动力。

Water can be made from oxygen and hydrogen .

水是由氧和氢组成。

Water can be made from oxygen and hydrogen.

This system could be paired with another electrode for the hydrogen side.

这个系统还可以与另一个电极耦合产生氢气。

Now Angela Belcher of the Massachusetts Institute of Technology and her colleagues have succeeded in mimicking the first part of photosynthesis by using a genetically modified virus to help split water into hydrogen and oxygen.

现在麻省理工学院的安吉拉。贝尔切和她的同事们成功模拟出了光合作用的第一部分，他们使用一种基因改良的病毒来促进水分解为氢气和氧气。

While hydrogen obtained from water is the gas that would be used as a fuel, the splitting of oxygen from water is the more technically challenging "half-reaction" in the process, Belcher explains, so her team focused on this part.

这种方法使产生氧气的效率提高了4倍，研究人员希望能够找到同样的以生物学为基础的系统来完成这个反应的另一半过程——分离氢气。目前，从水中分离的氢被分成质子和电子。

Based on the analyses of the chemical and the physical characteristics of hydrogen peroxide, the effect mechanism of H2O2 additive on diesel combustion was put forward and proved by the heat release rate of the single-cylinder engine test. The experimental results on 135 diesel engine bench show that H2O2 additive is effective to improve diesel combustion, and the specific fuel consumption, particulate matter and NO are decreased obviously.

对过氧化氢的化学及物理特性进行了分析，建立了过氧化氢组液影响内燃机燃烧过程的机理模型，并且通过放热规律进行了试验验证。135单缸机的试验结果表明，过氧化氢组液的效果相当显著，可以同时降低油耗以及碳烟和NO的排放。

Molar ratio of hydrogen to benzaldehyde was increased in consecutive hydrogenation process, which is beneficial to enhancing the selectivity of benzyl alcohol.

在苯甲酸甲酯加氢连续步骤中的氢醛比得到提高，有效地抑制了副产物甲苯的生成。

You can snipe the second and third union leaders from this position.

您可以鹬第二和第三工会领袖从这一立场出发。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
