In order to cope with the increasing traffic , an improvement to tuen mun road commenced in mid - 1994 . the provision of a climbing lane each in three critical uphill sections of tuen mun road in the kowloon - bound direction , namely sam shing hui , so kwun wat and ting kau , was completed in august 1996 为配合不断增加的交通量，屯门公路改善工程于一九九四年年中展开，以便在屯门公路往九方向的三个重要上山路段，即三圣墟，扫管笏及汀九，加建爬坡车道全部工程已于一九九六年八月完竣。
Universal type that guangzhou dongchen electric vehicle co . , ltd develop the latest electric car mix with the motive to become soon the green environmental protection motor car , it broke the traditional consciousness , the way that whole car lines that tradition of limitless become soon , that car have the zero row to put , free from pollution , have no the noise , mentally retarded consume , start steady , long drive route , excellent climbing ability , the special advantage of low etc . , function index sign of movement cost is already the advanced level , it broke the tool of traditional transportation means of transportation flowing freely of world , now a humanities culture for be in the leading , a nature consciousness for be in the leading 广州东辰电动车有限公司最新款的普及型混合动力变速绿色环保电动车，它打破了传统的无极变速方式，该车具有零排放、无污染、无噪音、低能耗、起动稳、行程长、爬坡力强、运行成本低等独特优点，性能指标已达世界先进水平，它打破了传统交通代步工具的局限意识，整车线条流畅，体现一种领先的人文文化，一种领先的自然意识。
In all control modes especially when ev starts up at low speed with full load , it realizes round magnetic chain , stator current observers and full speed control model and makes ev have higher torque , and good climbbing capability with constant power and have high output speed with constant torque . all of these above provide control system behavior with good robust and sidiling mode 在各控制方案中，尤其在电动汽车低速起动和满负荷低速行驶时，实现了圆形磁链的拟合，定子电流观测器和全速度控制模型控制方案，使电动汽车在恒功率状态下具有较大的起动转矩和爬坡提速性能，在恒转矩状态下具有较大的速度输出，从而使该控制系统达到了较好的鲁棒性、滑模性。
According to the special surface structure and actualities that the city is extending along the transportation line and river region because of the restriction caused by the mountains in the two sides of every cities in qingyang . the author thinks it is not good to squeeze out the existence of cave dwellings during the course of urban construction , and it is necessary to emphasize the symbiosis between urban and cave dwellings . the author conceives that it is feasible to develop group - dwellings in the steep - sides of mountain and especially to adapt to constructing " climb - slope cave dwellings which are covered with earth " 根据庆阳特殊的地表结构和城镇发展受两侧山体限制而沿交通线与川区无限蔓延的现状，笔者认为在庆阳城镇建设中不应完全排挤窑居的存在，而是要强调城镇与窑居的共生，并设想充分利用两侧陡坡地带发展居住组团模式，建设新型“爬坡式覆土窑洞”建筑群落，这种“城镇型窑洞”可作为城镇建设空间横向的延续和拓展，防止城镇呈线状无限蔓延的畸形发展态势；提倡运用现代科学技术对传统窑洞民居进行改造与创新，要加快新式窑居的试点建设；建议积极开发庆阳窑洞旅游资源，并提出了“窑洞地产”和“绿色窑洞产业”的全新概念。
I descried diu diu put the bike aside , and went ahead with her backpack , my tears came , actually there were three males members behind her , beside her , there were three backpacks , she needed not to carry on one backpack to go ahead when she was the end of her limitation 我远远的看见的丢丢在坡下丢下了车，自己背一个包继续爬坡，那一刻我的眼睛有点湿，其实后面还有三个男的，那地方还有风大哥丢下的两个包，一共是三个包，她没有必要在自己的体力到极限的情况下还背一个包继续走啊。
Make a brand with character , " when beautiful nimble " card report motor - car has the outward appearance novel and pure and fresh , the operation is handy , on the safe side , ride travel is comfortable , noise is low , service life is long , cost can be low , free from contamination , intelligent control , driving moment is big , climbing capacity is strong , glide performance is good , protective function is much , the characteristic such as function stability , once put in the market times accept consumer favour , make strong brand quickly 以品质打造品牌， “佳捷时”牌电动车具有外观新颖清新，操作简便，安全可靠，骑行舒适，噪音低，使用寿命长，耗能低，无污染，智能控制，驱动力矩大，爬坡能力强，滑行性能好，保护功能多，性能稳定等特点，一经投放市场就倍受消费者青睐，迅速成为强势品牌。
The cleaning cars has seven major characteristics : 1 , the vehicle design aesthetic appearance generous , simple , flexible cleaner compact cab from the sanitation workers in the rain , snow and inclement weather operations headaches ; 2 , jia lu cleaning electric car gearbox is my companys patented products , latin america is characterized by heavy goods , light down - climbing and extended battery life ; 3 , jia lu electric bicycle bridge cleaning car brake , the company is a patent product , is characterized by simple structure , convenient operation , maintenance easier , better braking performance ; 4 , good deer electric car cleaning dustbins with low human workers the high - school , so that sanitation workers can easily handling , reversing a good sight , and reduce incidents , high safety factor ; 5 , good deer electric cleaning trucks advanced electric power putter as a dump , the sanitation workers to reduce labor intensity , is characterized by fewer power failures , maintenance - free ; 6 , jia lu electric vehicle using toughened glass cleaning cars , advance reversing have good vision , difficult to scratch and ensure the safety of sanitation workers ; 7 , good deer by external electric car cleaning plate , a fiberglass liner internal , external characteristics : hinge not on the plate yi loose , often not dump deformation and withstand collisions , the internal use of fiberglass liner , not rust , corrosion , wear after the liner can be replaced , maintaining low cost 该保洁车有七大特点： 1 、该车外型设计美观大方，操作简单灵活,明净小巧的驾驶室免除了环卫工人在雨雪等恶劣天气作业时的烦恼； 2 、佳鹿电动保洁车变速箱是我公司的专利产品，特点是拉重货，轻松爬坡而且省电，延长电瓶的使用寿命； 3 、佳鹿电动保洁车后桥双轮制动，是我公司的专利产品，特点是结构简单，操作方便，维修容易，制动性能好； 4 、佳鹿电动保洁车超低的垃圾箱符合人体工程学的高度，使环卫工人能轻松地装卸，倒车时具有良好的视线，减少事故的发生，安全系数高； 5 、佳鹿电动保洁车采用先进的电动推杆作为自卸动力，减轻了环卫工人的劳动强度，特点是故障少功率大，免维护； 6 、佳鹿电动保洁车整车采用钢化玻璃，前进倒车都有良好的视线，不易划伤，保证环卫工人的安全； 7 、佳鹿电动保洁车外部采用钢板，内部采用玻璃钢内胆，外部特点：铰链在钢板上不易松动，经常自卸不变形，经得起碰撞，内部采用玻璃钢内胆，不生锈、不腐蚀，磨损后内胆可以更换，维护成本低。
In order to develop a new ev fast , low cost , high technology and according with the acquirement of the market , choose advanced vehicle simulation by computer is a good way . in this dissertation , advisor as a simulator , be used to simulate a new kind ev - xl2000 . in this dissertation , the author analyzed the technology of the ev , and founded the mathematics models of xl2000 with the battery , motor and the automobile , to simulate the dynamic property of xl2000 本文在对电动汽车相关技术进行了综合分析的基础上，根据xl2000纯电动汽车的特点，对动力电池、异步电机和整车受力情况建立了数学模型，主要对整车的动力性进行仿真，设定以下几项计算任务：工况行驶和续驶里程计算、最高车速、最大爬坡度计算和加速性能等，在学习advisor软件的基础上进行了开发，建立了xl2000型电动汽车的模型，并进行了动力性的计算。
