dsf

Build the LTP test suite and install it, and then change into the DSF directory.

编译ltp测试套件并安装它，然后切换到dsf目录。

Once in the DSF directory, you will see both kernel_space and user_space directories.

进入DSF目录后，您将看到kernel_space目录和user_space目录。

DSF is especially helpful in executing device driver kernel code where the device may not be present.

当设备可能不存在时，DSF特别有助于执行设备驱动程序内核代码。

To improve the consequent system performance degradation, system transmission medium DSF can be used.

为了改善由此造成的系统性能下降，系统传输媒质可以采用色散位移光纤。

At last, the calibrated value of LSF and DSF are used for testing the fused quartz sample with known modulus.

最终，使用校准后的载荷因子和位移因子去测试标准样品熔融石英，测试结果远远优于未经校准的值。
