同样，零-拷贝操作减少了耗费时间的用户态-系统态状态切换的次数，从而节省了时间。

Also, zero-copy operations reduce the number of time-consuming mode switches between user space and kernel space.

热力学系统的（火用）值在寂态等于零，其它任何状态都大于零。

Only in the dead state, does the exergitic value of a thermodynamic body equal zero, it is above zero in any other states.

索桁架的分析和计算，共有三种不同的状态：零状态、初始态、工作状态。

There are three states in the analysis and calculation of cable truss such as zero state, initial state and working state.
