七、单节锂电池的应用举例 1、 作电池组维修代换品 有许多电池组:如笔记本电脑上用的那种,经维修发现,此电池组损坏时仅是个别电 池有问题。可以选用合适的单节锂电池进行更换。 2、 制作高亮微型电筒 笔者曾用单节 3.6V1.6AH 锂电池配合一个白色超高亮度发光管做成一只微型电筒,使 用方便,小巧美观。而且由于电池容量大,平均每晚使用半小时,至今已用两个多月 仍无需充电。电路如图四所示。

四、锂电池的充放电要求; 1、锂电池的充电:根据锂电池的结构特性,最高充电终止电压应为 4.2V,不能过充, 否则会因正极的锂离子拿走太多,而使电池报废。其充放电要求较高,可采用专用的 恒流、恒压充电器进行充电。通常恒流充电至 4.2V/节后转入恒压充电,当恒压充电 电流降至 100mA 以内时,应停止充电。 充电电流(mA)=0.1~1.5 倍电池容量(如 1350mAh 的电池,其充电电流可控制在 135~ 2025mA 之间)。常规充电电流可选择在 0.5 倍电池容量左右,充电时间约为 2~3小

Mastering Kali Linux for Web Penetration Testing English | 2017 | ISBN-10: 1784395072 | 338 pages | AZW3/PDF/EPUB (conv) | 31 Mb You will start by delving into some common web application architectures in use, both in private and public cloud instances. You will also learn about the most common frameworks for testing, such as OWASP OGT version 4, and how to use them to guide your efforts. In the next section, you will be introduced to web pentesting with core tools and you will also see how to make web applications more secure through rigorous penetration tests using advanced features in open source tools. The book will then show you how to better hone your web pentesting skills in safe environments that can ensure low-risk experimentation with the powerful tools and features in Kali Linux that go beyond a typical script-kiddie approach. After establishing how to test these powerful tools safely, you will understand how to better identify vulnerabilities, position and deploy exploits, compromise authentication and authorization, and test the resilience and exposure applications possess. By the end of this book, you will be well-versed with the web service architecture to identify and evade various protection mechanisms that are used on the Web today. You will leave this book with a greater mastery of essential test techniques needed to verify the secure design, development, and operation of your customers' web applications.
