It's the way, for example, that foreign molecules or antigens get presented to cells of your immune system in order to start the process of making an immune response, so sometimes a cell/cell interaction.
通过这种方式,外源分子,或者说抗原,进入到免疫系统的细胞中后,就会开启免疫反应过程,有时候就是细胞之间的相互作用
You're going to have to know when you describe the system, if your system is homogeneous, like your coffee with milk in it, or heterogeneous like water with an ice cube in it So heterogeneous means that you've got different phases in your system.

And if you've ever heard the word driver software that you install in your computer so that your computer, your operating system, Windows or Mac OS, knows how to talk to that piece of hardware, it's that driver software that then empowers the operating systems to send those commands as well, up, the data is laid out on the disk.
并且如果你听说过安装到,电脑中的驱动软件这个词的话,你的操作系统,比如Windows或者是苹果操作系统,通过这个驱动软件我们的电脑,才能知道如何与这个硬件进行通信,正是因为这个驱动软件,操作系统才能根据数据,左右移动的指令来读取磁盘里的数据。
