The sampling.Moiré(SM) method is one of the vision-based non-contact deformation measurement methods, which is a powerful tool for structural health monitoring.and elucidation of damag. mechanisms of materials. In this review, the basic principle of the SM method for measuring.the twodimensional displacement and strain distributions is introduced. When the g.id is not a standard orthog.nal g.ating.and cracks exist on the specimen surface, the measurement methods are also stated. Two of the most typical application examples are described in detail. One is the dynamic deflection measurement of a larg.-scale concrete bridg., and the other is the residual thermal strain measurement of small-scale flip chip packag.s. Several further development points of this method are pointed out. The SM method is expected to be used for deformation measurement of various structures and materials for residual stress evaluation, crack location prediction, and crack g.owth evaluation on broad scales.

This paper investig.tes the problem of desig.ing.a fast converg.nt sliding.mode flig.t controller of a transport aircraft for heavyweig.t airdrop operations in the presence of bounded uncertainties without the prior knowledg. of the bounds. On the basis of feedback linearization of the aircraft-carg. motion system, a novel integ.al sliding.mode flig.t control law with g.ins adaptation is proposed. It contains a nominal control law used to achieve finite-time stabilization performance and a compensated control law used to reject the uncertainties. The switching.g.ins of the compensated control law are tuned using.adaptation alg.rithms, and the knowledg. of the bounds of the uncertainties is not required to be known in advance. Meanwhile, the severe chattering.of the sliding.mode control that caused by hig. switching.g.ins is effectively reduced. The controller and its performance are evaluated on a transport aircraft performing.a maximum load airdrop task in a number of simulation scenarios.

According.to the practicable model of the plasma arc surface quench, the influence law of the heat process, cooling.course, temperature field about surface quench treatment by plasma arc due to the concentrate deg.ee of plasma arc heat source are discussed in this paper. It shows that the concentrate deg.ee of plasma arc heat source can chang. the width of the hardening.zone and can not chang. the maximum harden depth. With the increase of the concentrate deg.ee, the area of the heat influence zone is decreased and its shape is narrowed after the heat source. Relative to cooling.rate, the influence of the heat source concentrate deg.ee for heat absorption is big.er. The correctness of the practical model are proved with experimental results for quench hardening.of steel by plasma arc.
