寒冬中的一缕温暖 DODGE Caravan 3.0V6

决定去拍照的这一天,恰逢北京冬天的第—场雪,天空也是无比阴暗,行驶在城市拥堵的公路上,到处都是肮脏的车辆,不时从你身边驶过,扬起一阵泥水,心情也是愈发烦闷。索性把车交给同事,沉沉睡去,也不知过了多久,睁开眼睛,我们已身处郊区,曾经多次走过的国道白得刺眼,两旁层峦叠嶂,竟如史诗般宏伟,我摇下车窗,点燃一支香烟,任寒冷的空气割面,仿佛大梦初醒……     

井盖的故事

1960年春天的一天,我们单位几个年轻的考验员,笑传一个消息:我们的刘组长,被李非处长批评了一顿。刘组长是大好人,建国前参加工作,三十多岁,就是爱叨唠,新领的驾驶本,技术不大熟练。李非是公安局交通管理处的处长,从延安过来的,听说上过抗大,当时在北京市的司机队伍里无人不知。因为他经常在司机安全大会上发表演说,不但嗓音洪亮,而且内容贴切,博古论今,风趣幽默,当然主题不     

天下泉城——济南

记得老舍先生在他的名篇《济南的冬天》中这样写到:对于一个在北平住惯的人,像我,冬天要是不刮风,便觉得是奇迹;济南的冬天是没有风声的。对于一个刚由伦敦回来的人,像我,冬天要能看得见日光,便觉得是怪事;济南的冬天是响晴的。自然,在热带的地方,日光是永远那么毒,响亮的天气,反有点叫人害怕。可是,在北中国的冬天,而能有温晴的天气,济南真得算个宝地。是的,济南

摇滚天堂

试想一下,你坐在车里,风吹在你脸上,听着Kent乐队微辣的摇滚乐,然后漫无目地在高速公路飞驰,当我问你为什么的时候,你也不知所以然。然后又突然感叹世间的美好,感觉就像个小文青。听Kent的作品就会有这些莫名的悲伤,这并非来自歌词,而是音乐本身阐述的一种感觉,这种感觉可能并没有文字表述的直白,没有影像来的概括,可却是最抓人     

让时光倒流 2011 Kawasaki W800

1998年,川崎仿古街车W650面世,主要定位于欧洲和日本市场。质朴简洁的造型,经典怀旧的韵味,可靠的性能,迅速赢得了一批怀旧的粉丝。不过,由于日渐高涨的环保呼声,采用化油器的W650不再能满足日趋严格的排放标准,于2008年停产,让很多复古迷们惆怅不已。好消息终于传来,2011年W650的新一代接班人浮出水面,在继承W650古色古香的造型和韵味的同时,搭载了排量更大的电喷并列双缸,让等候多时的川崎迷们得偿夙愿。

男人四十而不惑,除了稳定的日复一日的工作和生意,生活总是陷于平淡,世俗,忙碌。想出去走走,但一直未能如愿。我喜欢在宽敞公路上飞驰的感觉,喜欢随心所欲的骑行,浏览美好的景色;喜欢约上三两个朋友骑上摩托车,沿着陡峭的山路或蜿蜒的公路,去体验充满乐趣的摩旅生活。对我而言,世界上没有什么能比这种出行更激动人心了。所以,我和两位好友决定,驾一辆BMWF650GS(达喀尔)和两辆隆鑫无极LX650,今天就出发,杀向泸沽湖。     

Modeling phone use prevalence and risk assessment among long-haul truck drivers in India

Research on distracted driving due to phone use has increased substantially over the past decades, however, very little is explored about commercial vehicle drivers (e.g., truck drivers) in this aspect. This study focused on examining the prevalence of phone use habits and the associated crash risk for data collected from 490 Indian truck drivers. The data on demographic details, driving history, phone use habits (in everyday life and during driving), history of receiving any penalty for phone use and incidences of crash occurrence, was collected through face-to-face interviews with the drivers. Binary logistic models were used to identify the factors affecting phone use habits during driving and the associated crash risk. Further, the incidences of receiving a penalty for the phone use were examined through cross-tabulation and chi-square statistics. The results showed that 55% of the drivers used a phone during driving, mainly for talking purpose. The model revealed that education, vehicle size, vehicle ownership and everyday life phone use habits were the significant factors associated with phone use while driving. Regarding the history of penalty receiving incidences, 41% of the drivers who used a phone during driving had received the penalty, and 52% of these penalty-receiving drivers were penalized repetitively. The model results for crash risk showed that the frequent phone users were 29 times more likely to be involved in a crash due to phone use compared to the non-frequent users. The results suggest a double level (legislative and company level) prohibition policy for phone use during driving for the truck drivers and also to enforce strict and effective legislative ban especially on the truck routes.     

私车公用视角下的广西林业类事业单位公车改革

长期以来,广西林业类事业单位公务用车存在运行成本高、公车私用、超编制超标准配备使用车辆、使用效率低等问题。虽然在国、区两级政策的指导下,广西林业类事业单位通过体制改革,公车私用、配备不合理、使用效率低等现象有所改善,但车辆运行成本高的问题仍然突出。本文就林业类事业单位公务车辆运行成本过高的问题原因进行了分析,借鉴社会企业普遍使用私车公用的策略,探索广西林业类事业单位公车改革的途径,以期为林业类事业单位公车改革提供有益借鉴。     

Attitude toward physical activity as a determinant of bus use intention: A case study in Asuke,Japan

This study examines the effect of people's attitudes toward physical activity on their bus use intentions in rural areas in Japan. We utilized the theory of planned behavior and designated three variables—attitude toward bus use, subjective norms, and perceived behavioral control—as mediators for the hypothesized effect. Analysis results showed that attitude toward physical activity had a significant effect on bus use intention. For transport policy, this implies that improving attitudes toward physical activity can increase bus use and reduce physical inactivity, partly caused by car dependence. Results from a multiple-group analysis, for the hypothesized model, revealed that this finding is particularly valid for young people, car drivers, and people living within five minutes of the nearest bus stop. Finally, the effect of attitude toward physical activity on bus use intention is higher with the presence of mediators; these mediators help to increase the model's predictability for the variance of bus use intention from 8.6% to 64.4%.

A control strategy for parallel hybrid electric vehicles based on extremum seeking

An energy management control strategy for a parallel hybrid electric vehicle based on the extremum-seeking method for splitting torque between the internal combustion engine and electric motor is proposed in this paper. The control strategy has two levels of operation: the upper and lower levels. The upper level decision-making controller chooses the vehicle operation mode such as the simultaneous use of the internal combustion engine and electric motor, use of only the electric motor, use of only the internal combustion engine, or regenerative braking. In the simultaneous use of the internal combustion engine and electric motor, the optimum energy distribution between these two sources of energy is determined via the extremum-seeking algorithm that searches for maximum drivetrain efficiency. A dynamic programming solution is also obtained and used to form a benchmark for performance evaluation of the proposed method based on extremum seeking. Detailed simulations using a realistic model are presented to illustrate the effectiveness of the methodology.

电动汽车电气绝缘检测方法的研究

为了达到一定功率要求,电动汽车需要多个蓄电池串联使用,电池组的总电压一般高于100V,纯电动大型客车的电压高达500V,并且电动汽车的使用环境比较恶劣,由于振动、冲击、温度以及电池腐蚀性液体的影响。一旦因为绝缘性能下降导致高压系统出现问题,影响电动汽车的正常使用,文章从电动汽车的构成出发,探究绝缘性能下降的原因,并提出如何检测电气绝缘的方法。     

基于妥尔油脂肪酸的沥青温拌剂的研制

目前国内外表面活性剂类沥青温拌剂的使用是主流，其结构主要是脂肪酸酰胺。原材料主要采用动物和植物油脂，造成产品的合成成本居高不下，同时由于产品的凝固点高，使其在低温环境下使用不便。现研制的SWMA沥青温拌剂采用的主要原料为从造纸废液中回收的妥尔油脂肪酸，既充分利用了废弃资源，又降低了产品成本，同时妥尔油脂肪酸的低凝固点，使产品可以在低温保持较低的粘度，方便其在低温环境下的使用，且该产品合成工艺新颖，结构组成方式独特。该沥青温拌剂的研制成功有利于降低沥青温拌剂使用成本，推动国内沥青温拌技术更大规模的应用。
