The fine structure constant, and other fundamental constants, are absolutely central to our current theory of physics.
微细构造常数和其他基本常数都无疑是我们现在研究的核心。
For functions and constants, if the current namespace does not contain that function or constant, PHP's fallback mechanism will fall back to the standard PHP function.
对于函数和常量,如果当前的名称空间不包含这个函数或常量,PHP的后退机制会后退到标准的php函数。
The current at the channel base is specified, and use two time constants can get the much better shapes than single time constant.
模型对于特定的雷电通道底部电流,采用了汉时间常数,取得了比单时间常数更好的拟合效果。
In the above example we define some constants, get the site path, and also check to make sure that the current PHP version is at least5.1.
在上面的例子里我们定义了一些常量,得到了站点的路径,并且还检查了当前的PHP版本至少应该是5.1。
The equivalent time constants are derived from the decay characteristics of the induced current. The resistance and inductance can be given by calculating the eddy current loss an…
等效时间常数可以从感应电流自然衰减特性得到,电阻和电感则通过计算被动反馈线圈中涡流损耗和磁场能量中求得。
