The corrosion fatigue crack growth and near-threshold characteristcsof high tensile steel HT60 were investigated by using the compact specimens underexposure to synthetic sea water. The da/dN vs △K_ relation in air may be conser-vetivel estimated for that in sea water. In the high △K region with high stressratio, owing to the acceleration of crack growth promoted by stress-induced dissol-ution, the crack opening stress intensity factor K_ represents only the result ofcrack surface in contact with corrosion products, so as to give an overestimation ofK_ at crack tip.

In contrast, assembly of mobile hard disk, although the manufacturer can also install high-speed hard disk to your hard disk box, but due to the lack of synchronization control chip technology and can not interface with the hard drive to eliminate the bottleneck between the speed, so that assembly of a "high-speed mobile hard disk" can not truly reflect the advantages of high-speed hard drive, it is very easy because the interface with the speed difference between the hard disk, and there waiting for data transmission, data underrun issues.

The status quo of high-resolution data acquisition system is discussed and by studying the character of high-resolution seismic exploration and seismic signal, the theoretical models and character of each unit are gained. This paper point out that under 1000 meter's depth where petroleum is embedded the IDR of central controlled seismic instrument and telemetricseismic instrument are lower than 70dB which can't meet the needs of high-resolution seismic exploration.
