内燃牵引 meaning in Chinese
diesel traction
Examples
- By analyzing the relation between the train passing capacity and tunnel length as well as tunnel slopes the upper and lower limits for installing mechanical ventilation in railway double track tunnel have been determined , which provides science foundations for the formulation the ventilation design norm for railway double track tunnels in operation
通过对列车通过能力与隧道长度和坡度关系的进一步研究，得出了内燃牵引双线铁路隧道设置机械通风的上、下界限，为双线铁路隧道运营通风设计规范的制订提供了科学依据。 - New technology on china " s railway traction is experiencing changing periods from internal - combustion traction to electrical traction and from dc drive to ac drive , which make it possible for the railway enterprises to face pportunities and challenges . it " s up to these enterprises to take the initiative in making development while producing electric driver of locomotives
我国铁路牵引技术正处于由内燃牵引向电力牵引、由直流传动向交流传动转换的时期；使配套生产机车电传动装置的铁路电机企业的新产品开发面临着机遇和挑战。 - A study on the limits for installing mechanical ventilation in railway double track tunnels in operation has been conducted . both numerical methods and field tests were used in the study . first , present situation of railway double track tunnels ; diesel locomotives with its pollutant emissions , and tunnel environmental hygienic standard ( tb1912 - 87 ) were reviewed
目前我国内燃牵引双线铁路隧道还没有设置机械通风的界限，针对这种情况，本文采用数值计算方法，结合现场试验，并根据tb1912 - 87的卫生标准，对设置机械通风的界限进行了深入的研究。
