10. Cycle life varies depending upon application-specific
characteristics. Actual results will vary.
11. Per United Nations material classification UN3499, all
Maxwell ultracapacitors have less than 10 Wh capacity
to meet the requirements of Special Provisions 361.
When packaged according to the regulation, both
individual ultracapacitors and modules composed
of those ultracapacitors shipped by Maxwell can be
transported without being treated as dangerous
goods (hazardous materials).

C++ 属于面向对象的编程语言，OOP的思想不必多说，特别对于复杂的软件工程来说，利用OOP绝对是事半功倍，相对于传统的C来说； 当然用C来写单片机程序无可厚非，已经延续了一个传统，从大学时学的开始到工作岗位，好多人都是一直用C来做，但是既然Keil支持C++编译， 可以用C++来编写你的代码，可以利用高级语言来结构化，清晰化你的程序，为嘛不用呢！哈哈，个人看法！下面进入正题： C+...[详细]
