As this relation evolves in depth in terms of their interactionality, heterogeneity and complicatedness, later reasearchers are increasingly attaching more importance to the matter of population economy drived fom the relation between humans and enviroments of resources, thus extending the connotation of the relation to a multiple structure or a macro-field, and beginning a more rational research into the way mankind survives against the background of globalization, with the idea about the sustainable development as the central guidance.
The studies on the pruning technique of apple-pear showed that,the body structure of the tree,changed from dense type to loose type,and from multiple structure to dual structure,which can improve fruit quality and inter-crop yield. Because it accelerate air circulation and broaden light area,it can increase sunlight utilization and solve the problem that inter-crop needs plenty of light.
Only carries out the system reformation,breaks the monopolization of electric power industry,stimulates the enthusiasm of masses,can distributed total energy production and supply system with multiple structure develop.
From the concept of multi-structure, the article analyzes the background and the actual need of the coming into being of structure, states the multi-structure form in architecture creating, and puts forward new ideas and new methods for architecture creating in the future.
According to the characteristics of geology of the levee foundation in Dongting Lake region,covering soil layer model in multi-structure levee foundation has been established; through changing the width or thickness of covering soil layer,optimization study is carried out by seepage FEM.
Farmer's modernization is the premise and inevitable outcome of agricultural modernization,which contains the improvement of farmer's qualities and their material and cultural life, farmer's freedom from agriculture,and the rural pluralistic structure as well.
Multiple structure of two-pulse nuclear spin echo in cobalt films
It is shown that the multiple structure of the echo from 59Co nuclei at T=4.2 K is due to a mechanism in which an additional hyperfine magnetic field proportional to nuclear magnetization is acting on the nuclear spin system.
Broadening of the lines due to several experimental factors, the multiple structure of the lines and the characteristics energy losses are taken into account.
This zone revealed a multiple structure which also showed up in the distributions of O3 and condensational nuclei concentrations measured with the Sabre-linear aircraft of the National Center of Atmospheric Research.
Results show that the typical morphology of these active regions is a δ-type sunspot with a single multiple structure, in which there are many umbras with different magnetic polarities, packed tightly by a single penumbra.
Edge detection method of remote sensing images based on mathematical morphology of multi-structure elements
Based on multi-structure elements of gray mathematics morphology, in the light of difference between noise and edge shape of RS images, the paper establishes multi-structure elements to detect edge by utilizing the grey form transformation principle.
Correlation functions for multi-structure landscapes exhibit an increased correlation length, especially near the melting temperature.
The multi-structure of oxidized-reduced tungsten carbide surface(s)
Figure 5 compares the collected jitter delays from NetPerf and the jitter delays produced by the proposed multi-structure jitter model.
