Analysis results showed that the bands of CoLL′ in the ultraviolet region arose from π~b→π~* transition of ligand and the bands (400~500 nm) in the visible region belonged to the charge transfer from ligand 5-NO_2-phen to ligand mnt~(2-) in the observed spectra essentially.
In essence, the indexing investment is a passive investment strategy, and corresponding to the positive investment which is through active research and analysis (including technical analysis and fundamental analysis) to achieve excess return of stock market.
It is in this shape process of the capitalist world economy, the international labor separation of metropolitan state and colony countries, the nature of it is the European colonial countries control the countries, and it is prolonged till the world system nowadays, and that determines that the economy globalization, in nature, is a economic movement launched and directed by advanced capitalist countries.
Compared with dominant curriculum,hidden curriculum is of important influence on students′ values and college moral education as a form of course,which lies in campus material culture,college regulations and campus spiritual culture.
Results Cell automaton is a kind of car-following model,reaction(t+T)=sensitivity × stimulus(t) is a successful mathematic model,random factors is very important in traffic model.
The space itself can be characterized essentially as the domain where the generalized Bergman operator is nondegenerate.
We construct essentially all the irreducible modules for the multiparameter quantum function algebraF?φ[G], whereG is a simple simply connected complex algebraic group, and ? is a root of unity.
We prove that having a quasi-metric on a given set X is essentially equivalent to have a family of subsets S(x, r) of X for which y∈S(x, r) implies both S(y, r)?S(x, Kr) and S(x, r)?S(y, Kr) for some constant K.
Recognizing essentially disconnected benzenoids with fixed double bonds
Essentially disconnected systems are Kekuléan pericondensed benzenoid systems with some fixed double or single bonds.
The aim of this paper, in essence, is to study certain ergodic properties of this latter transformation group.
At that, the law in essence must be independent of the plant's dynamic characteristics and the environment.
Its distinctive feature lies in the fact that in essence the dynamic characteristics of the mechanical system are unknown.
In essence, these studies highlight the novel anti-angiogenic, antioxidant, and anti-carcinogenic potential of a novel anthocyanin-rich berry extract formula, OptiBerry.
An analysis of these characteristics makes it possible to conclude that the total porosity in opals comprises macropores, which are in essence the voids between structure-forming spheres, and nanopores connected to the substructure of the spheres.
Their phenomena, patterns, and applications in nature and society are introduced.
Complex networks describe a wide range of systems in nature and society.
Cellulose is a kind of renewable resource that is abundant in nature.
For this reason, emphasis is placed on specific features of explored metabolic pathways that can be used for constructing new enzymatic systems not present in nature.
Seasonal changes in the abundance and sex ratio in the hog slater were monitored in nature throughout the annual cycle.
A basic eguation for predicting 500 mb topography is obtained on the followingtwo assumptions:(1)the level of P=O is a horizontal plane,(2)its height H doesnot change with time.This equation is very similar to that for barotropic case,but withcertain essential differences.In this article,author also points out that in the barotropiccase,taking a smaller grid we will get a better result than that of alarge grid.Theexamples of forecasting show that this method is rather successful.
Starting from the fundamental equations of electric machine, this paper develops an analytic method of investigation of the self-excitation problem of asynchronous machine connected through series capacitor. Constant synchronously rotating system components dc and qc and method of small oscillational equations are used in the analysis; steady state oscillational principles, spectrum frequency analysis of discriminating occurrence of self-excitation are discussed. Correlation between these methods are also described....

Correlation between these methods are also described. Results obtained from this theoretical analytic method are compared with those obtained from experimental tests, the agreement between them is very close. It is found that the basic nature of self-excitation phenomenon of asynchronous machine, as shown from the results of this investigation, is a kind of resonance among the electro-mechanical parameters of the machine. Traditional methods of analysis, being used so far by many writers, regarding the speed of the machine as a constant factor, cannot reveal the effect of rotational inertia of the machine upon the self-excitation process.
