太阳能光伏效应,简称光伏(PV),又称为光生伏特效应(Photovoltaic),是指光照时不均匀半导体或半导体与金属组合的部位间产生电位差的现象。[1]人们通常不会将连接光伏组件和逆变器的布线系统视为关键部件,但是,如果未能采用太阳能应用的专用电缆,将会影响到整个系统的使用寿命。太阳能系统常常会在恶劣环境条件下使用,如高温和紫外线辐射。在欧洲,晴天时将导致太阳能系统的现场温度高达100°C。目前,我们可采用的各种材料有PVC、橡胶、TPE和高质量交叉链接材料,但遗憾的是,额定温度为90°C的橡胶电缆,还有即便是额定温度为70°C的PVC电缆也常常在户外使用,显然,这将大大影响系统的使用寿命。——2014年中国光伏市场应用浅析就光伏应用而言,户外使用的材料应根据紫外线、臭氧、剧烈温度变化和化学侵蚀情况而定。在该种环境应力下使用低档材料,将导致电缆护套易碎,甚至会分解电缆绝缘层。所有这些情况都会直接增加电缆系统损失,同时发生电缆短路的风险也会增大,从中长期看,发生火灾或人员伤害的可能性也更高。而在安装和维护期间,电缆可在屋顶结构的锐边上布线,同时电缆须承受压力、弯折、张力、交叉拉伸载荷及强力冲击。如果电缆护套强度不够,则电缆绝缘层将会受到严重损坏,从而影响整个电缆的使用寿命,或者导致短路、火灾和人员伤害危险等问题的出现。2012年,由于GDP增速放缓,并且我国的工业增速多半可能会继续保持一个适度回调。再加上由于利润越来越薄,许多企业不惜为了赚取利润生产不合格、伪劣产品。有的企业迫于市场压力,选择最低价竞标,这诸多因素更是给我国的电线电缆行业发展带来很大的瓶颈。因此,加大电线电缆产品质量提升工作可谓是迫在眉睫、刻不容缓。

我以前本科和研究生都学过商务、全球化还有翻译,所以还算比较了解。花了半个多小时翻译的,译文如下:Nowadays, globalisation is growing rapidly, which influences the development of business where enterprise Although globalisation homogenizes people’s preference throughoutthe world, each country’s cultural is deep- The cultural differencesamong countries have significant impact on the internationalisation of anenterprise, which encourages their internationalisation or Internationalisation of a companycan be achieved through merging and OFDI (outward foreign direct investment),but transnational operation of a company tends to be influenced by the The disadvantage caused by the cultural differences is the culturallyrisk that cultural conflict brings to the development strategy of the internationalisationof a This increases the cost of transnational operation, but your understandingof the cultural traits of the host country will well facilitate the internationalisationof the The United States and China are culturally different, thereforewe have different enterprise In the process of enterprise internationalisation,both the companies in China and the US have its own traits ininternationalisation, and their development is significantly influenced by Through the analysis, this paper argues that the cultural conflictsand integrating capability of transnational operation of a company is the keyfactor that impacts the success of the internationalisation of the Thedifferences of companies’ values, background and the lack of effective communicationare the critical reasons that lead to the enterprise cultural The practiceof cross-culture operation is fundamental to the success of an international It is also significant to the implement of the strategy of enterprise Based on the previous studies of other researchers, this paper focuses on thefact of companies in China and the US, and provides suggestions to the solutionof the cultural conflicts in the internationalization of a 具体文章不知道,可能有一些不准确的地方,你先看看
