电容器是三大被动元件之一，应用广泛，主流按照介质进行分类。电容器是电子线路中必不可少的基础元件，与电阻、电感并称三大被动元件，具有“通交流、阻直流”的特性，广泛应用于各种高低频电路和电源电路中。一般按介质不同分为陶瓷电容、铝电解电容、钽电容和薄膜电容等四大类。

尽管我国的加氢站建设速度加快，但数量上仍低于日本和德国，且存在地区间分布不均衡的特点。目前我国的氢燃料电池产业已形成了地区产业集群，各具不同的优势，各地相继推出政策扶持氢能产业园，整体并未形成很清晰的协同发展体系，但考虑到现在氢燃料电池产业仍处于导入期，在政策指导和补贴支持下，未来仍具较大的发展空间。

目前行业有两条相对明确的主线：1、目前国内市场处于触底企稳阶段，伴随国内纯消费市场渗透率提升以及营运市场政策预期加强，国内新能源汽车销量将逐步走出困境，行业龙头将受益于集中度提升的过程；2、海外供应链从落地到放量，各环节海外业务占比较高的龙头将优先受益。同时我们认为2020 年新能源汽车与3C 数码行业有望迎来较高增长，原材料钴环节将存在较大的价格弹性，新型碳纳米管导电剂也会受益于行业渗透率快速提升。

我们预计新基建相关方向的投资与建设将加速展开，特高压输电作为新基建的重要组成部分，预计将有超过10 条线路开始进入建设周期，相关主设备市场空间约600 亿元，核心供货企业有望显著受益；维持行业强于大市评级。

当前，市场受疫情影响波动性较大，那么2020年风电行业的发展情况如何，风电板块是否可能成为投资避风港？这篇报告回答了投资者们普遍关心的几个问题。当前风电投资与装机量如何？各地政府和能源主管部门的态度与规划？开发商们的招标项目与价格怎样？一季报要如何看待？生产进度能否在年内追回？海外疫情严重有何影响？当前特殊时期的投资逻辑是什么？

Fiber optic cables contain strands of glass fibers inside an insulated casing. They are designed for long-distance, high-performance data networking and telecommunications. When compared to wired cables, the fiber optic cables provide higher bandwidth and can transmit data over longer distances. Fiber optic cables support the internet, cable television, and telephone systems. While most fiber optics are installed to support long-distance connections between cities and countries, some residential internet providers have invested in extending their fiber installations to the suburban neighborhoods for direct access by households. A fiber optic cable is less susceptible to interference. A copper network cable requires shielding to protect it from electromagnetic interference. While this shielding helps, it is not enough to prevent interference when many cables are strung together in proximity to one another. The physical properties of fiber optic cables avoid most of these problems.

Batteries that provide power supply to forklift trucks or used in forklift trucks are usually known as forklift batteries. They need high power and energy density. Generally, lead-acid and lithium-ion batteries are used in the forklift trucks as per convenience during material handling operations. Lead-acid batteries come with a mixture of electrolyte, water, and sulphuric acid; on the other hand, lithium-ion batteries are waterless that makes them maintenance-free. The report on the global forklift battery market focuses on the current market trends and future growth opportunities of various types of forklift batteries. Based on type, the global forklift battery market covers lead-acid battery, lithium-ion battery, and others. On the basis of application, the global market is characterized into warehouses, manufacturing, retail & wholesale stores, construction, and others. Region wise, the global market is analyzed across North America, Europe, Asia-Pacific, and LAMEA.

经济增长两架马车消费和出口受新冠肺炎疫情冲击较大，新基建投资有望拉动经济。“新基建”以科技发展为核心，包含七大领域，分别为5G基站、特高压、城际高速铁路和城市轨道交通、新能源汽车充电桩、大数据中心、人工智能、工业互联网。经济增长两架马车消费和出口受新冠肺炎疫情冲击严重，2020 年1-2 月份社会消费品零售总额为52130 亿元，同比下降20.5%，进口商品总值同比跌幅4%，出口商品总值同比跌幅17.2%，疫情冲击致使消费与出口两辆马车受创，短期之内投资将成为经济增长关键因素。

检验检测作为生产性服务行业，主要为生产活动提供各种支持的服务，具有专业性强、创新活跃、产业融 合度高、带动作用显著等特点。掌握了检测话语权一定程度上也就意味着掌握了质量和标准的定价权，是 全球产业竞争的战略制高点。

燃料电池龙头，内生+外延并购不断拓展燃料电池产业链。巴拉德成立于1979 年，过去四十年公司陆续收购Dantherm Power、Protonex、AFCC 等多家公司或资产持续拓展燃料电池产业链，目前公司产品包括上游膜电极（MEA）与双极板等，中游燃料电池电堆、模组和动力系统，实现燃料电池领域的全面覆盖。2019 年公司整体营收达到1.063亿美元，同比上升10%；毛利率达到21%，EBITDA 为-2800 万美元。短期来看由于公司历年来研发投入等资本开支较大，一直处于亏损状态。
