提出了一种自调节种群的演化算法(SaPEA)求解旅行商问题,算法根据当前最优适应度改进的情况提出一种更精细调节种群规模的模式,并根据演化的进程选择强化操作或者分化操作。这样不仅有利于保持种群的多样性开发新的解,还可以加快收敛速度探索到更好的解。同时,还对现有的启发式交叉算子和3-opt局部搜索算法进行了改进。通过对TSPLIB中实例进行测试,表明了SaPEA算法的优越性。

In this paper the author presents an overview on his own research works. More than ten years ago, we proposed a new fundamental equation of nonequilibrium statistical physics in place of the present Liouville equation. That is the stochastic velocity type’s Langevin equation in 6N dimensional phase space or its equivalent Liouville diffusion equation. This equation is time-reversed asymmetrical. It shows that the form of motion of particles in statistical thermodynamic systems has the drift-diffusion duality, and the law of motion of statistical thermodynamics is expressed by a superposition of both the law of dynamics and the stochastic velocity and possesses both determinism and probability. Hence it is different from the law of motion of particles in dynamical systems. The stochastic diffusion motion of the particles is the microscopic origin of macroscopic irreversibility. Starting from this fundamental equation the BBGKY diffusion equation hierarchy, the Boltzmann collision diffusion equation, the hydrodynamic equations such as the mass drift-diffusion equation, the Navier-Stokes equation and the thermal conductivity equation have been derived and presented here. What is more important, we first constructed a nonlinear evolution equation of nonequilibrium entropy density in 6N, 6 and 3 dimensional phase space, predicted the existence of entropy diffusion. This entropy evolution equation plays a leading role in nonequilibrium entropy theory, it reveals that the time rate of change of nonequilibrium entropy density originates together from its drift, diffusion and production in space. From this evolution equation, we presented a formula for entropy production rate (i.e. the law of entropy increase) in 6N and 6 dimensional phase space, proved that internal attractive force in nonequilibrium system can result in entropy decrease while internal repulsive force leads to another entropy increase, and derived a common expression for this entropy decrease rate or anothe

change of proton gradient across thylakoid membrane in soybean leaves was studied with millisecond delayed light emission (ms-DLE) during the course of state transitions which were indicated by the chlorophyll f{1.ores-cence at room temperature and 77 K. When dark-adapted leaves were induced to stateⅠ with far-red light, Fm/Fo, F685/F735 and the intensity of fast phase of ms-DLE were af-fected slightly. However, during the induction to stateⅡ with red light, both Fm/Fo and F685/F735 decreased immedi-ately and the former were quicker than the latter. In this interval, the intensity of fast phase of ms-DLE increased to a maximum and then decreased to a lower va{1.e during the transition to stateⅡ. Nigericin, an uncoupler which elimi-nates the proton gradient across thylakoid membrane, inhib-ited the increase in the intensity of fast phase of ms-DLE during the transition to stateⅡ. Another uncoupler, valino-mycin, which eliminates the membrane potential, did not affect the changes of the intensity of fast phase. These results suggest that the prompt increase in the intensity of fast phase of ms-DLE at the beginning of transitions to stateⅡ is cor-related mainly with the proton gradient released from water oxidation in photosystemⅡ.

The mechanism of methanol adsorption induced by oxygen and the effect of water on the methanol oxidation on electrolytic silver have been studied by ultra-high vacuum temperature programmed reaction spectroscopy(TPRS), transient response method and isotopic exchange experiment. It has been found that oxygen adsorbed on silver can greatly promote methanol adsorption and can also react with methanol to produce water. Experimental results show that oxygen in the water comes from the adsorbed oxygen and hydrogen from the methyl and the hydroxyl in methanol. It has also been found that there exists competitive adsorption between water and oxygen on silver and water can increase the selectivity of methanol oxidation to formaldehyde. This result is consistent with the catalytic activities.

Bacteriorhodopsin(BR)exhibits,as a membrane protein in Halobacterium salinarum,unique photoresponsive behaviors,and shows promise as a functional information material.A new mutant of BR with the 96th aspartic acid replaced by valine(BR-D96V)was obtained and then a composite film of BR-D96V in a synthetic polymer matrix was prepared in this *** mutant BR-D96V was expressed in a bacterio-opsin deficient halobacterial strain(L33)by gene *** valine is very hydrophobic,this point mutant keeps the basic biological activities,namely,photoelectric and photochromic ***,the lifetime of M intermediate in the BR mutant is nearly two orders of magnitude longer than that of wild-type BR in neutral aqueous solution,which benefits its potential application as an information *** M lifetime is further significantly prolonged after embedding BR-D96V into poly(vinyl alcohol)(PVA).It was also found that BR-D96V is very sensitive to water content in comparison with wild-type BR and another BR mutant.

Let X be a Stonian space and C∞(X) the Riesz space of all extended realvalued continuous functions from X into R-(=[-∞, +∞]). By Ω∞ we denote the collectionof all extended Riesz homomorphisms φ from C∞(X) into R with φ(Ix) = 1. In thispaper, we obtain that the Stonian space X is realcompact if and only if for every φ ∈Ω∞there exists a unique x ∈ X such that φ(f) = f(x) for any f ∈ C∞(X). When the Stonian space X is realcompact and Ω∞ is equipped with the topology induced by C∞(X), it is proved that Ω∞ is homeomorphic to X.
