STUDY ON BOUNDARY EFFECT OF THE TEST MODEL OF DEEP HOLE BENCH BLASTING
According to particular form of (0.1.1), we overcome the difficulties caused by boundary effect by employing some function transformations and the " maximum principle " of first-order quasilinear hyperbolic system, then obtain the existence of global solution to the initial boundary value problem (0.1.1) - (0.1.3).
This paper analysed the spatial distribution of FDI manufacturers in Shenzhen in terms of density, industries, ways of investment and investment source, and it classified the distribution mechanism of the manufacturers into five categories: planned effect, passage effect, border effect, centre effect and connecting direction effect.
In this paper, non-ideal detonation phenomenon of condensed high explosives including border effect and wave front transition of diffraction detonation, detonation trigger and energy utilization efficiency , reaction rate and structure of detonation wave are verified using theory analysis, numerical simulation and relevant experiment results, and mechanism and law of these phenomenon are preliminarily studied from the following aspects such as pressure profile, energy transform and kinetic energy output.
Furthermore,it is difficult to harvest the undergrowth vegetation by using the small simple size since lots of shrubs were too large to be encircled in it. Considering the impacts of edge effect and variation of the biomass relative mean value,we suggested the optimum size of 2 m×1 m for undergrowth biomass sampling and 10 quadrats with the same size may control the standard error within 10% of the biomass average value.
Adjustment approach to boundary effect on aggregation index and its application
Calculating aggregation index by the sample-plot data used to lead to computing error due to the existence of a boundary effect.
Here, we suggest a method for adjusting boundary effect in the analysis of spatial patterns at different stages of development of the broad-leaved Korean pine forest.
Based on the sampling data, a correct approach to the boundary effect on aggregation index was put forward to the spatial pattern analysis of the broad-leaved Korean pine forest in its different stages of development.
Biological significance of the observed "boundary effect" of selenium as a manifestation of plant antioxidant protection is discussed.
