The Science Behind hDc
1、McDavid hDcTM starts with a patented process that permanently bonds hydrophilic (water-attracting) molecules to mid-weight and heavyweight synthetic fiber surfaces. This ensures that the performance of hDcTM remains intact even after numerous washings unlike any other moisture transport technology currently available. (See care instructions for details.)
2、As you exercise, your body produces perspiration to cool itself. In warm conditions, this perspiration condenses on your skin and builds up heat. (And discomfort.)
3、Moisture is pulled away from the skin by the wicking ability of hDcTM . Your skin remains cooler and drier, and your body's temperature management system can do its job more effectively.
4、Once the fabric absorbs the moisture, it is spread rapidly across a broader surface area for faster evaporation. It is this evaporation which draws heat out of the body.
5、Once the moisture is one molecule thick, hDcTM starts its drying process, allowing for a consistent and rapid moisture transport ability over a long use time. McDavid hDcTM evaporates moisture faster than any other fabric after the initial washings, including any modified cross-section fiber.
HDC坡道自动控制系统
HDC是路虎独有的专利技术，该系统可以控制车辆从陡峭或较为光滑的大坡上平稳驶下。使用时，只需把变速箱手柄置于1挡或倒挡，然后再按一下手柄旁边的HDC键，就会以每小时6公里的速度匀速下坡，这时驾驶者可以不踩刹车踏板，只需控制好方向盘就能安全到达坡底。
HDC其他行业术语：
1.hdc是重载连接器的术语！
2.HDC在重载连接器行业上的英文全拼是：Heavy Duty Connector
HDC在c++中的解释：
Device Contexts
A device context is a structure that defines a set of graphic objects and their associated attributes, as well as the graphic modes that affect output. The graphic objects include a pen for line drawing, a brush for painting and filling, a bitmap for copying or scrolling parts of the screen, a palette for defining the set of available colors, a region for clipping and other operations, and a path for painting and drawing operations. The remainder of this section is divided into the following three areas.
hdc在MFC中：
CDC是MFC的DC的一个类
HDC是DC的句柄,API中的一个类似指针的数据类型.
MFC类的前缀都是C开头的
H开头的大多数是句柄
这是为了助记,是编程读写代码的好的习惯.
CDC中所有MFC的DC的基类.常用的CClientDC dc(this);就是CDC的子类(或称派生类).
CDC等设备上下分类,都含有一个类的成员变量:m_nHdc;即HDC类型的句柄.
记住下面的一句话,会有助于你的理解.
MFC的类,是在用window API语句开发出来的有一定功能的小程序.(也可称为类).使用它的默认方法,就是,记住它的名字与参数(可以用笔记,代替脑记).
