THEMAllE型剑杆织机的断经停车是由经停杆、经停片相配合完成的,其原理是:断经后经停片落下,使经停杆的杆芯和外皮连接通电而使织机停车.我公司在用THEMAllE型剑杆织机织造纬纱为防静电纱织物品种时,在织造一个班8h左右时会出现无故断经停车现象,随着时间的推移,该现象越来越频繁,乃至无法开车.经分析认为:防静电纬纱在织造过程中会有少量纤维落下,而这些纤维是导电的,当纤维落到经停杆的杆芯和外皮之间(间距为2mm)达到一定量之后,会使杆芯和外皮连接通电而造成断经停车.为此,我们采取了如下措施对断经自停装置进行改造.

本文从工程应用实践角度,对高速公路电子不停车收费系统的检测指标进行了深入分析,对检测方法的确定进行了研究,并对检测仪器的选取进行了探讨.

车开着开着眼看有些年头了,虽说咱家的车子任劳任怨从来不叫一声苦、不喊一声累,着实让吾等爱车一族感动得热泪盈眶.可是,每每这车一上路,或泊进停车场,在群车之间我那车的外表一样着实地让吾辈"感动"得热泪盈眶-太难看了.

文化的传播需要一定的载体.体育传播是以竞技比赛、体育活动、娱乐休闲等为载体的交流和信息交换行为.我国古代体育文化总是附着于军事、竞技游戏以及养生健身、侠义精神以及宗教仪式等特定的社会现象中继承和传播的.

面对市场经济化,停车服务业正在经历从被动地"为顾客服务"向主动地"使顾客满意和成功"的转变过程,传统停车场在停车效率、安全、性能、管理与营销上已不能满足现代化的停车发展需求.文中从面向停车功能需求与停车业发展需求出发,提出由智能停车场管理系统与泊车商务系统构成的综合泊车管理平台,并分析了两大子系统的相关内容,指出智能停车场管理系统应包括管理信息系统、信号及标志诱导系统、电子收费系统、停车场监控系统和停车费电话及网络查询系统五大部分,泊车商务系统应包括泊车商务网、网站管理系统、停车管理系统、营销管理系统和客户服务系统五大部分.

计重收费实施后,车辆超载情况得到了一定程度的治理,通行车速、路面损害等都得到了改善,但也出现了一些新的问题,突出表现在:收费站(特别是省界主线收费站)的通行能力明显下降;计重设备的精度可靠性不稳定,导致收费纠纷增多.利用物联网技术,提出了一种基于物联网的货车电子不停车计重收费方案构想-使用电子封签监测货车上的货物情况,并依赖网络,监测跟踪货车运输的全过程,将货车计重这个环节,从集中在收费站出口车道,改为分布到各个物流中心、仓库、港口码头等货运集散地,减少了计重环节对收费站出口的压力,实现了货车的电子不停车计重收费,提高收费站出口的通行能力.

如今,报知春节迫近的已经不再是腊八粥的香味,而是媒体上充满压力的热火朝天的春运了.每入腊月,春运有如飓风来临,很快就势头变猛,愈演愈烈;及至腊月底那几天,春运可谓排山倒海,不可阻遏.每每此时我都会想,世界上哪个国家有这种一年一度上亿人风风火火赶着回家过年的景象?

二语词汇习得中的石化现象直接阻碍了学习者的语言表达及运用能力.二语习得者如果过分地依赖于高频词汇,结果则是其产出性词汇无论在广度还是深度上都很难进一步提高.因此,教师应该鼓励并在教学中采用一定的教学策略促使学生尽量多运用刚学的新词,而非一味依赖以往熟知的高频词汇,使学生的语言表达更加准确、恰当和丰富,从而促进其英语水平的不断提高.
