Since about 4.5kg of the gas is needed to cover 480km (about 300 miles), the typical range of a petrol-powered car, this would translate into a rather large 284-litre tank stuffed with some 300kg of carbonised chicken feathers, according to Mr Senz.

燃烧石油的汽车在加满油的情况下通常能跑480公里（约合300英里），如果使用氢气的话，大概需要4.5公斤，根据Senz的估计，这就意味着需要一个284升的油箱，在里面塞满约300公斤的碳化鸡毛。

The edge of the gas stations to sell food store with several different types of bottled water, but the prices are from 1 to 5 dirhams dirhams range (equivalent to RMB 2 ~ 10 million), it seems, water is more than oil expensive also.

而加油站边上的食品店里出售着几种不同的瓶装水，价钱从1迪拉姆到5迪拉姆不等（相当于人民币2~10元），这样看来，水的确是比油还贵啊。

Synthesized all above, the heat and mass transfer of charge bed is discussed in detail. After choosing seriously the former study results in this field, a whole temperature range process model for firing iron ore pellets containing solid fuel is established as well as its software is edited. The main physical chemistry reaction process within pellets and the heat statement can be calculated exactly with the process as long as the physical and chemical parameters of raw material are obtained through basic experiments. After finding out the reason of"temperature hysteresis"and"heat inertia"of the experimental induration device, a new kind of experimental induration device is designed. The"temperature hysteresis"of hot gas flow in the new device is avoided.

综合以上对焙烧球团矿时球团矿内各种物理化学反应过程的分析与研究的结果，仔细地分析研究了球团矿料层中的传热质现象，认真筛选了前人对填充床的传热传质的研究结果，提出了全温度范围球团矿焙烧过程模型，并编制了相应的计算机软件，只要通过基础实验，获得原燃料的基本物性参数（如化学反应速度常数，矿粉、煤粉的粒度及此表面积以及球团矿的导热性等），利用这一软件就能准确地计算出焙烧球团矿时球团矿内各种物理化学反应过程和料层内的热工状态。

6The gas cell with two electrode pairs is very simply constructed,convenientand suitable for any range of wavelength.

6双电极气体池，结构简单，使用方便，并且不受检测波长的限制，为直接检测XUV提供了一种简便的方法。

Analysis method of ammonia in coking wastewater by means of gas sensitive electrode was introduced in the paper and also were analysed the linear range,response time,reused ratio and interfering substance.

The oscillation performance of jet, as oscillation frequency, is the essential data for designing the fluidic device, which is also the key factor that influence the coupling effect of fluidic device and receiving tube. This paper does experiment on the oscillation availability and frequency of feedback jet-oscillation gas wave refrigeration. As a conclusion, the jet oscillates only in a certain range of geometrical sizes and operating conditions. Under the condition of high pressure ratio, the frequency of the jet"s oscillation is only affected by the feedback tube"s length and chamber remarkably. Under the condition of low pressure ratio, the frequency descends with rise of the pressure ratio.

本文将跨音速正反馈射流振荡器与接受管耦合，对耦合后的射流振荡气波制冷机的可振性、振荡频率以及它们的影响因素作了实验研究，得出如下结论：射流只在一定的操作条件和几何结构尺寸范围内才能稳定振荡；射流的振荡频率在较高压比下只受反馈管长和反馈管容腔大小的显著影响，在小压比下随压比的增大而增加；其它结构尺寸和操作条件只影响可振性。
