With 'Hongmanao', a sweet cherry cultivar from central Shanxi Province, as the experimental material, the chilling requirements of different types of fruit branches (including mixed fruit branch, long fruit branch, medium fruit branch, short fruit branch and blossom fruit branch) were studied by the 0-7.2 ℃ model in a solar greenhouse during 2012-2013. In the greenhouse, the fruit branches of 'Hongmanao' were cultured in water in a thermostatic environment. The results showed that the chilling requirement of leaf buds of 'Hongmanao' was lower than that of its flower buds; and the chilling requirements of the five types of fruit branches ranked as blossom fruit branch's〈short fruit branch's〈medium fruit branch's〈long fruit branch's〈mixed fruit branch's, 展开更多

In this paper, a three dimensional matrix valued rational interpolant (TGMRI) is first constructed by making use of the generalized inverse of matrices. The interpolants are of the Thiele type branched continued fraction form, with matrix numerator and scalar denominator. Some properties of TGMRI are given. An efficient recursive algorithm is proposed. The results in the paper can be extend to n variable. 展开更多

In this study,based on two CMOS cameras,an orthogonal optical observation platform has been set up for positive streamer branches under 1 m rod-plate air gap.The Monopodia branch and the Dichotomous branch have been proposed for steamer branch classification.The branch length,the branch angle and the optical diameter are statistical obtained and compared for the two branch types under different impulse voltages.The empirical function between the branch length Ls and the inception voltage Ui of the Monopodia branch has been obtained.The distributions of the branch angle and the axial angle of the two types have been given,and the mean optical diameters have been provided.Based on the comparisons,the formation mechanism of the two branch types has been proposed.This experimental result can provide the basic data to the numerical calculation of positive long air gap discharge. 展开更多
