Furthermore, author provides the definitions of demarcation point and demarcation line based on the consumption trap and the marginal price curve, and finally builds the models of linear optimal pricing, improved second order non-linear optimal pricing and improved third order non-linear optimal pricing.
According to the relation between the creep deformation and time increment under different stress density conditions the relationship of creep deformation with concrete stress is found and the demarcation point between linear creep and non—linear creep of compressive concrete is gained. In addition,a convenient and suitable expression in terms of the function of a non—linear stress is presented.
The amount criterion for constituting the conversion crime determines and reflects the extent of harm to the society, which is the dividing point of the conversion in the transition from violating the law to committing a crime.
This paper depicts in detail the creation and the modification of the division point, the initial centroid and the current centroid, and finally discusses the English topic detection algorithm based on the double centroids topic model, which is proved to be successful by experiments.
The relationship between N, K contents or the N/K ratio and quality of flue-cured tobacco was studied through field trials. Results showed that:(1) There was a curvilinear correlation between total sugar contents of cured leaves and the contents of available K in soils at maturing stage. Contents of available K in soils had a point of demarcation, 113.33mg/kg in mature stage.
Taking the valley of the distribution curves as the dividing point, two height classes were apparent with a segregation ratio of 3 tall∶1 short, demonstrating this character to be under the control of a single recessive gene.
There appears to be a systematic variation in δO18 from the most S-type to the most I-type granites, the dividing point between the two occuring at δO18 equal to 10.
The diagrams are entered with "per cent of combined groups above dividing point" and difference between groups in their per cents above the dividing point.
This dividing point εL decreases with increasing coordination number.
By shifting the dividing point between the two parts of the period, we identified the point showing the greatest possibility of structural change.
