This study examined the ecological changes on the southern slope of Qilian Mountains in China from the perspective of water conservation by classifying different clusters of water conservation functional areas to efficiently use limited human resources to tackle the water conservation protection problem. In this study, we used Integrate Valuation of Ecosystem Services and Tradeoffs(InVEST) model to estimate water conservation and analyzed the factors that influence the function. The results of this study include:(1) from 2000 to 2015, the water conservation of the southern slope of Qilian Mountains generally showed an increasing trend, and the total water conservation in 2015 increased by 42.18% compared with that in 2000.(2) Rainfall, fractional vegetation cover(FVC), and evapotranspiration have the most significant influence on the water conservation of the study area. Among them, water conservation is positively correlated with rainfall and FVC(P<0.05) and negatively correlated with evapotranspiration(P<0.05).(3) The importance level of water conservation functional areas gradually increases from northwest to southeast, and the region surrounding Menyuan Hui Autonomous County in the southeast of the southern slope of Qilian Mountains is the core water conservation functional area. And(4) the study area was divided into five clusters(Cluster Ⅰ–Cluster Ⅴ) of water conservation, with the areas of Clusters Ⅰ through Ⅴ accounting for 0.58%, 13.74%, 41.23%, 32.43%, and 12.01% of the whole study area, respectively.展开更多

It shows that a crystalline silicon solar ceil with an intermediate band located at 0.36 eV below the conduction band or above the valence band can reach a limiting efficiency of 54% at the maximum light concentration, improving greatly than 40.7% of the Shoekley-Queisser limit for the single junction Si solar cell. The simulation also shows that the limiting efficiency of the silicon-based solar cell increases as the bandgap increases from 1.1 eV to 1.7 eV, and the amorphous Si solar cell with a bandgap of 1.7 eV exhibits a radiative limiting efficiency of 62.47070, having a better potential.展开更多

In order to give the exact solutions of random Burgers equation, we only consider the Wick-type stochastic Burgers equation which is the perturbation of the Burgers equation with variable coefficients by white noise W(t)=Bt, where Bt is a Brown motion. The auto-Baecklund transformation and stochastic soliton solutions of the Wick-type stochastic Burgers equation are shown by the homogeneous balance and Hermite transform. The generalization of the Wick-type stochastic Burgers equation is also studied.展开更多

Crystalline rocks are...Compositions, proportions, and equilibrium temperature of coexisting two-feldspar in crystalline rocks are of great importance to classification in petrography and interpretation of petrogenesis. Crystalline rocks are usually composed of 4-6 minerals (phases), depending on their independent chemical components and the equilibrium temperature of crystallizations. In general, number of mineral phases can be determined by the "Phase Rule". According to the mass balance principle, bulk composition of coexisting two-feldspar could be evaluated from the bulk chemistry of a rock, provided that the compositions of the coexisting mafic mineral phases containing calcium, sodium, and potassium oxides are determined, e.g., by microprobe analysis. The compositions, proportions, and temperature of two-feldspar in equilibrium can thus be simultaneously resolved numerically from bulk composition of the rock, by incorporating the activity/composition relations of the ternary feldspars with the mass balance constraints. Upon the numerical approximation method presented in this paper, better-quality, internally consistent data on feldspar group could usually be obtained, which would be expected more realistic and accurate in consideration of thermodynamic equilibria in the system of crystalline rocks, as well as bulk chemistry of a rock and the composing minerals.展开更多

Based on the harmonic balance principle, which is widely used in the frequency analysis of nonlinear control systems, a theoretical approach is used to investigate the conditions of system parameters under which this fractional-order system can give rise to a chaotic attractor. Finally, the numerical simulation is used to verify the validity of the theoretical results.展开更多

Causes of risks are directly linked to behaviors and decisions of major interest holders. In this paper,those causes are studied through the analysis of interest game between local governments,original land users,and property developers. The prevention and control of those risks requires balance of interest between interest holders to make possible multiple parties' engagement and interest sharing.展开更多
文摘The principle of the best interests of the child,as a criterion for substantive review,is conceptually ambiguous and uncertain in its application.To mitigate this dilemma in the application of the principle of the best interests of the child,the European Court of Human Rights(ECHR)has made a procedural transition in the interpretation and application of this principle,shifting from conducting specific proportionality analysis or interests balancing in cases related to children to examining whether States Parties have applied the principle of the best interests of the child in their judicial procedures.Moreover,ECHR has developed three procedural review schemes:holistic reviews,key factors-based reviews and factor list-based reviews.Compared with substantive reviews,procedural reviews adhere to the ECHR doctrine of margin of appreciation,restrict the free discretion of the court,give play to the effect of procedural autonomy,and pursue the value of subjective procedural justice,which has its own unique theoretical value and practical significance,and provides a feasible reference for China to interpret and apply the principle of the best interests of the child.

文摘Strasbourg’s application of proportionality test has some unique features.Due to the Court inherent subsidiary role,it hardly transplants the formulas and criteria adopted by the German Constitutional Court or Court of Justice European Union(CJEU) in the complete sense.Consequently,the Strasbourg application of the proportionality has been depicted as a "mysterious house" for the reason that it lacks of certainty.Therefore,some scholars often worry the application of the proportionality test will threaten the predictability and the Strasbourg rule of law.Generally,the proportionality test has two internal functions for the Strasbourg judges:(1) strike fair balance between/among the competing interests;(2) testing on the reasonableness and appropriateness between the measures employed and aim pursued.In the first category,the primary task of the Court is to protect the scope of "essence" of the Convention rights from the interference of collective goods relying on the interest-based rights theory.Beyond this scope,the Court would have to balance the interests explicitly incorporated into the Convention rights as well as the external collective goods claimed by the state authorities.In some sensitive judgments,the Strasbourg Court tends to impose the onerous responsibility of "burden of proof" to the State authorities,or strategically defers to the domestic decisions unless they will be found "manifestly unreasonable".Secondly,the Court must take a scrutiny towards the appropriateness between the means employed and ends pursued,and then it has to decide whether a less intrusive alternative existed or will possibly be found or not.Sometimes,the Court might impose state authorities an obligation looking for a new alternation.However,due to subsidiarity characteristic of the Strasbourg Court,the task of the assessments sometimes is complicated and time-consuming,so the Court are not capable of evaluations in all occasions.Finally,the Court could strike down the "chilling consequence" caused by some few of the legitimate measures which may highly potentially threaten the individual rights in the National legal order.
文摘Burgers equation in random environment is studied. In order to give the exact solutions of random Burgers equation, we only consider the Wick-type stochastic Burgers equation which is the perturbation of the Burgers equation with variable coefficients by white noise W(t)=Bt, where Bt is a Brown motion. The auto-Baecklund transformation and stochastic soliton solutions of the Wick-type stochastic Burgers equation are shown by the homogeneous balance and Hermite transform. The generalization of the Wick-type stochastic Burgers equation is also studied.
文摘One group of SiC films are grown on silicon-on-insulator (SOI) substrates with a series of silicon-overlayer thickness. Raman scattering spectroscopy measurement clearly indicates that a systematic trend of residual stress reduction as the silicon over-layer thickness decreases for the SOI substrates. Strain relaxation in the SiC epilayer is explained by force balance approach and near coincidence lattice model.

文摘Abstract:The concept of“basic rights and interests”in the re-cordation review system serves as a key to understanding the mixed use of review standards by the review authorities.The essence of the“basic rights and interests”concept is the value foundation estab-lished by the community for individuals,playing a legitimizing role in the actual operation of the state power system.Through the method of“triple abstraction,”the substantive construction of“basic rights and interests”can be achieved.Ensuring the“basic rights and interests”of citizens can effectively fulfill the functional purpose of the recorda-tion review system.The diverse human rights norms in China’s legal system are the formal carriers of basic rights and interests,which can be categorized into four types:human rights norms in policies,human rights norms in the Constitution,human rights norms in departmental laws,and human rights norms in social and cultural consensus.By examining the interactive connections of these diverse human rights norms,citizens’“basic rights and interests”can be organized into such five categories as survival care,democratic participation,cul-tural education,well-being development,and ecological harmony.The protection of“basic rights and interests”depends on the review authorities’application of the“basic rights and interests”concept to conduct mixed reviews of relevant normative documents.The applica-tion method should be based on the principles of integration,effective-ness,entirety,and harmony.

文摘Compositions, proportions, and equilibrium temperature of coexisting two-feldspar in crystalline rocks are of great importance to classification in petrography and interpretation of petrogenesis. Crystalline rocks are usually composed of 4-6 minerals (phases), depending on their independent chemical components and the equilibrium temperature of crystallizations. In general, number of mineral phases can be determined by the "Phase Rule". According to the mass balance principle, bulk composition of coexisting two-feldspar could be evaluated from the bulk chemistry of a rock, provided that the compositions of the coexisting mafic mineral phases containing calcium, sodium, and potassium oxides are determined, e.g., by microprobe analysis. The compositions, proportions, and temperature of two-feldspar in equilibrium can thus be simultaneously resolved numerically from bulk composition of the rock, by incorporating the activity/composition relations of the ternary feldspars with the mass balance constraints. Upon the numerical approximation method presented in this paper, better-quality, internally consistent data on feldspar group could usually be obtained, which would be expected more realistic and accurate in consideration of thermodynamic equilibria in the system of crystalline rocks, as well as bulk chemistry of a rock and the composing minerals.
文摘In this paper, the fractional-order Genesio-Tesi system showing chaotic behaviours is introduced, and the corresponding one in an integer-order form is studied intensively. Based on the harmonic balance principle, which is widely used in the frequency analysis of nonlinear control systems, a theoretical approach is used to investigate the conditions of system parameters under which this fractional-order system can give rise to a chaotic attractor. Finally, the numerical simulation is used to verify the validity of the theoretical results.
文摘Combining the principle of homogeneous balance method, the exp function expansion method and traveling wave transformation method are applied to the Equalwidth equation to obtain the exact solution of the Equalwidth equation. The obtained solutions include trigonometric functions, hyperbolic functions and rational functions. The method can solve the exact traveling wave solutions of other nonlinear evolution equations.
文摘In the context of economic globalization,territory-based bilateral trade statistics are no longer compatible with the reality of cross-border flow of capital factor and rapid emergence of multinational firms.On the basis of survey of literature studies,this paper has created a three-country model of bilateral trade based on ownership principle and demonstrated that ownership-based statistical system under this model can reflect bilateral trade volume and balance more objectively,truthfully and comprehensively.In addition to theoretical demonstration,this paper has revaluated China-US trade balance using ownership-based statistical methodology and the result indicates that the existing statistical system of trade severely overestimates the real level of China-US trade balance and FDI in China is a major reason behind increasing China-US trade surplus.
基金the preliminary achievements of the social science key research projects of Anhui Province:research on Risks of Urban Stock Land use Alteration(No:SK2014A212)the preliminary achievements of open subjects of the Center for Urban Management Research of Anhui Jianzhu University:research on Risks of Urban Stock Land use Alteration
文摘In China,a more strict approval system has been introduced against urban stock land use alteration,but the uncertainty of this system,due to its unclear statement on disposition,restraints and profit sharing,makes landuse alteration come along with risks of return loss of state-owned real property,recycling of stock land,imbalance of interest sharing,embezzlement of public land and pollution of industrial land. Causes of risks are directly linked to behaviors and decisions of major interest holders. In this paper,those causes are studied through the analysis of interest game between local governments,original land users,and property developers. The prevention and control of those risks requires balance of interest between interest holders to make possible multiple parties' engagement and interest sharing.
