The purpose of this dissertation is to study a principle or method to describe and analyze the complex problems with high gradients arising from practical engineering. The main contents cover:1. The Bezier function was introduced to approximate high gradient functions, and a suitable coupled function was derived. Some detail numerical results show that the Bezier-based function is dominant over other combination function such as polynominal and trigonometric series, when to describe a high gradient function.

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.
