    A proper total coloring of a graph G is an assignment of colors to the edges and vertices of G in such a way that no two adjacent vertices,no two adjacent edges,and no incident vertex and edge receive the same color.In this paper,the authors weaken the constraints of the proper total coloring to obtain several general total colorings and  discuss their chromatic numbers.

    Non-metric multidimensional scaling (NMS) analysis was used to get two direct gradients in canopy tree species-site relationships from canopy data set,then principal components analysis was used to extract two principal components (PC1 and PC2) from canopy variables including the two direct gradients and other canopy parameters as the environment variables of understory vegetation,and how the two principal components affect understory vegetation was studied,not only in species diversity and composition but also with reference to species assemblages.No significant effect of forest structure (represented by PC1 scores) on diversity of understory vegetation was found,however canopy composition (represented by PC2 scores) has a strong influence,explaining 36.9% variation in understory species diversity.DCCA (detrended canonical correspondence analysis) ordination to was used to explore the changes in understory species composition-canopy relationships,and canopy variables was found to significantly influence the distribution of the understory species.For example,Elaeocarpus decipiens,Aleurites Montana,Elaeagnus pungens,Cyclobalanopsis glauca,Diospyros kaki. var. sylvestuis and Cinnamomum parthenoxylon are strongly associated with forest structure,and Hemiboea henryi,Anisocampium sheareri,Akebia trifollata,Dendrobenthamia honghongensis and Phoebe sheareri are strongly associated with canopy composition.However forest structure is much weaker than canopy species composition in explaining understory composition.Null-model was also used to test the understory species co-occurrence patterns along three different forest structure and canopy composition scales.Only canopy composition significantly influences Stone and Roberts's C-score.The results suggest that canopy composition is among the most influential forces in ecosystem process,and imply that canopy composition might have played a major role in creating observed understory community patterns.

    Mercaptoacetic acid-stabilized CdTe quantum dots were prepared by hydrothermal synthesis method.The CdTe quantum dots exhibited absorption at 502 nm and fluorescence emission at 538 nm,respectively.When surface-modification of CdTe quantum dots were replaced with BSA,absorption peak and the fluorescence peak remained the same,while absorption intensity and the fluorescence emission intensity increased.The effect of pH、temperature and ion strength on fluorescence intensity were discussed.Under the optimal conditions,a mass concentration of BSA in the range of 0.05~1.0 mg/L shows a linear relationship with the fluorescence intensity increasing value of CdTe quantum dots,with a detection limit of 0.011 7 mg/L.The proposed method was applied to detection of the concentration of BSA in buffer solution.

    After the cold war,the US-Japan alliance has been making adjustment to the change of the international pattern.And now,restraining and encircling China has become the strategic goal of the US-Japan alliance.This certainly offends China’s core interests and is closely connected with China’s national security.However,because of the interest conflict,the collision of ocean strategy,cultural difference,world pattern and China’s development,there are many contradictions in the US-Japan alliance.Therefore,China should seize the opportunity and appropriately handle Sino-US and Sino-Japan relations.
