燃料消耗

This, in turn, contributes to a reduction in fuel consumption.

这反过来又促进了燃料消耗减少。

What's the fuel consumption ?

它的燃料消耗是怎么样呢？

Firstly, from Gauss' equations and relative motion equations, the relation of control impulse and relative motion was expressed as analysis formulas and simplified based on the near circular condition. By deeply analyzing the mechanism of impulses in each directions (radial, in-track and cross-track directions) effect on relative motion respectively, two maneuvers to establish formation flying are provided: one is to utilize the impulses in radial and cross-track directions, the other is to utilize the impulses in along-track and cross-track directions. Both of the two methods can establish satellite formation flying of any configuration. The method with impulses irradial and cross-track directions needs only 3 impulses, while the method with impulses in along-back and cross-track directions needs 4 impulses. Lastly, by an example of establishing a space-circle formation flying, two maneuvers were compared with each other in the amount of impulses and fuel consuming estimation.

首先由高斯型拉格朗日轨道摄动运动方程得到轨道坐标系中控制冲量与轨道根数偏差的关系，基于近圆轨道的条件简化并带入相对运动方程，得到控制冲量与相对运动的关系表达式；通过深入分析各个方向（径向、沿迹向与轨道面法向）的控制冲量对相对运动的影响，给出了分别用径向与轨道面法向控制冲量组合和沿迹向与轨道面法向控制冲量组合实现编队捕获的两种控制策略；最后给出了一个空间圆编队捕获实例，并从燃料消耗、施加冲量次数及捕获时间等角度对比研究了两种控制策略的特点。

Relationships between the instantaneous emission / fuel consumption rate and the instantaneous speed/acceleration are first analyzed. Then, the emissions for a variety of vehicle types in the network are analyzed. Finally, the developed platform is used to evaluate the impact of alternative traffic control and management strategies for two scenarios.

本文首先建立了车辆的瞬间尾气排放率、燃料消耗率与瞬时速度、加速度之间的关系；然后，对研究路网的各种车型的尾气排放量进行分析和计算；最后，通过两个假设方案，对不同的交通管理与控制策略对于尾气排放的影响进行分析。

We need to reduce amount of cars that running on the road to decrease the consumption of usage of fuel.

我们需要通过减少道路上的车辆以降低燃料消耗。

Protection from the wind is of the outmost importance to keeping the consumption at a low level.

防风对于降低燃料消耗来说是至关重要的。

The heat exchanger can reduce the energy consumption; the spray scrubber can make the temperature of exhaust gravitate; the condensing electrostatic precipitator can abate the oil mist and odor. The new technology can achieve the better effect of the environment. The problem of the tenter frame exhaust treatment is that the mist can't efficiently treat. The treatment of the tenter framer exhaust is late start.

染整定型的能耗占纺织工业总能耗的40%，通过热量回收可以减少定型过程燃料消耗，喷淋洗涤可以对染整定型机废气进行有效的降温，经过冷凝式静电除尘器深度处理，彻底消除透明度差和恶臭气味的影响，达到较高的环境效益。

This reduces 'slip' in the hydraulic torque converter benefiting both fuel consumption and CO2 emissions.

这将减少'滑'的液力变矩器利于燃料消耗和二氧化碳排放量。

An EcoFLEX Sports Tourer with low emissions and fuel consumption also will debut in Paris.

一个EcoFLEX运动旅行车与低排放和燃料消耗也将首次在巴黎举行。

Pulse detonation engine is a new concept of propulsive engine which uses high temperature and pressure gas produced by intermittent or pulsant detonation wave to generate thrust. PDE has many desirable advantages, including high thermal dynamic cycle efficiency, low specific fuel consumption, high thrust/weight and specific impulse, simple configuration, and will become propulsive device of aviation and spaceflight aerocraft in 21st century.
