natural measure
4.1. The ice flood disaster of Yellow River is very complicated phenomenon, in other words, It has natural and social feature, the influence of this disaster would reduce rock bottom if we combined project measure with non-project measure, the dynamic RS monitoring with GIS is effective one of non-project measure.
7.We prove that if μ is a nonnegative Borel measure on Ω, then the natural inclusion J:C(Ω)→L 1(μ) is an absolutely summing operator and a Pietsch integral operator with ‖J‖ as =‖J‖ pint =μ(Ω), and the regularity of μ guarantee that the vector measure G:Σ→L 1(μ), defined by G(E)=χ E, is the representation measure of J.
9.According to the measure and research on the biomass of natural secondary ?Quercus liaotungensis? stand in Lixian county at the upper reaches of Minjiang river,the results are as follows:?(1)natural? secondary ?Quercus liaotungensis? stand biomass reaches 488.49 t/hm?2,in which the arborous layer biomass is occupying 99.22% of the total and the sequence of other layers is:litter layer>shrub layer>moss layer>herb layer;
10.If a certain peak value is too high, it will have greater influence on the intensity of the vibration noise of the whole structure, the corresponding measure can be taken according to the form of the structure vibration to change the modal natural frequency, damping, stiffness and quality of the step, making the natural frequency of the structure move to the hard vibration area.
