When CRT monitors are used, VRAM is dual ported, allowing one port to continuously refresh the display while another port writes data to the display.

当使用CRT显示器时，VRAM是双端口的，允许一个端口不断地刷新显示，而另一个端口写入需要显示的数据。

Related to the loss of enclosure damping, ported and dual-reflex bandpass designs also exhibit higher distortion levels at very low frequencies than sealed or single-reflex bandpass designs.

从箱体阻尼损失来看，导向孔和双反射带通箱设计在极低频下比密封箱和单反射式带通箱设计有着更大的失真。

Next in line, the wide-bandwidth dual-reflex and the ported enclosure exhibit very good efficiency as well.

接下来，宽带双反射带通和导向孔箱体也有很好的效率。
