    摘要： A stress testing method of a file system includes traversing local or network storage devices with a drive letter; detecting a network mapping path of the network storage devices; calculating an absolute path of all the storage devices through a mounted point and a system volume; collecting the above information to update the path information of the file system; and then calling a corresponding test algorithm and stressing strategy according to different types of storage devices, so as to perform the stress test. The stress testing method can make the file system display storage devices without a drive letter, and call appropriate testing methods and stressing strategies for different types of storage devices, so the depth and scope of the stress testing for file system are expanded, the accuracy of the test is enhanced, and the problem of occupying too many system resources is avoided.

    摘要： A peripheral component interconnect (PCI) bus test system and method therefor, that is applied in a PCI test card. The PCI test card includes a static random-access-memory (SRAM). In the method, the data transaction of the PCI bus signal is disintegrated into a separate data operation, while eliminating the waveform interfering transaction. Through comparing the waveform of the data operation as separated from a PCI bus signal with the standard PCI bus waveform, the quality of the PCI bus signals can be precisely analyzed, thus realizing the hardware test of PCI bus.

    摘要： A conductive carbon nanotube film having high tensile strength and initial tensile modulus comprises primarily oxidized small-diameter carbon nanotubes wherein the diameter of the small-diameter carbon nanotubes are at most about 3 nm. A method for making the film comprises refluxing an aqueous mixture comprising carbon nanotubes and an oxidizing agent to form a refluxed nanotube dispersion; forming a carbon nanotube film from the refluxed carbon nanotube dispersion; optionally removing nitric acid or other oxidizing agent from the carbon nanotube film; drying the carbon nanotube film; and heat-treating the carbon nanotube film to form a heat-treated carbon nanotube film. The method can also comprise sonicating the nanotubes prior to or after refluxing. A heat-treated small-diameter carbon nanotube film can have a tensile strength of over 70 MPa and an initial tensile modulus of about 5 GPa.
