查询词典 compared with

The high efficiency and high power semiconductor laser with multi-active regions which are cascaded by reverse biased tunnel junction has a higher inner quantum efficiency which can larger than 1, so that it can output higher optical power at the same injected current compared with the normal lasers, meanwhile, it can be designed to large coupled optical cavity, so it will increase the limit of the electro-thermal destroy and the COD.

On global optimal algorithms, a heuristic 0-1 Integer Liner Programming algorithm is achieved, which combines heuristic enumeration method and revised simplex method. Simulation experiments show that the degree and optimization efficiency in our algorithm is obviously improved compared with the MATLAB 7 bintprog function that is a 0-1 integer programming algorithm. Moreover our algorithm isn\'t relevant to the scale changes of Web services composition and candidate service sets, thus it is applicable for the scenes that the scales of Web services composition changed dynamically. But for Web services composition with service alliance, the algorithm is unable because the non-linear global optimal model of the fitness function and QoS constraints can\'t be expressed in linear mode.
