In the modern world, the number of species threatened with extinction, however, far outstrips the current resources available for their conservation, and the situation looks set to become rapidly worse [2, 4].
The habitat heterogeneity hypothesis proposes that an increase in the number of habitats leads to an increase in species diversity in a landscape, because of an expansion in the number of partitionable niche dimensions, which facilitate specialization and avoid competition through spatial segregation [16].
A number of studies have found weak correlations among the three plant diversity measures because different controlling factors are responsible for the geographical patterns of different aspects of species diversity [9, 10-12, 15].
Furthermore, counties are widely used in China as the fundamental administration units in the management of local biodiversity conservation practice, and are also used as spatial units in a number of broad-scale biodiversity studies [5, 7, 20-22].
In addition, though grain size has been cited as a confounding factor in relevant studies [52-56], Feng et al (2011) showed that spatial associations among the three types of diversity measures at grid scale did not differ significantly with those at county scale [8], which, to certain extent, was consistent with Larsen and Rahbek [57].

Microscopic observation showed that grain formation led to the increase in strength [10].
This was due to the fact that pulse discharge energy increases with increase on Ton leading to a faster cutting rate in sample 1 but in sample 2 the cutting speed may be decreased due to increase in number of RHA particles, as the machinability decreases with the increase in RHA.
Also due to presence of a greater number of RHA particles in composite the electrical conductivity decreases in the MMC sample which is reducing cutting speed as discharge power decreases.
As the pulse off time declines, the number of discharges within a specified time period turn out to be more which leads to increase in cutting speed.
Adjusted R2 [R-sq(adj)] is a modified R-sq that can be adjusted for the number of terms in the model.

A small amount of black carbon produced by combustion are dissipated in the form of soot, and a large number of them are stored in the soil [10-11].
In addition, this research also found that different grain size of soil organic carbon had remarkable linear or logarithmic relationship with the content of black carbon, which may mean that black carbon play an important role in the sequestration process of organic carbon in soil.
Fifth, compared with the liquid phase method, the plasma method can avoid a large number of spent liquor.
This method was commonly used in the black carbon industry, so there were a large number of related literature resources [33-34].
Local farmers had the habit that they burnt the sugar cane straw in the sugar cane fields for a long time, so the agricultural soils had accumulated a large number of black carbons.

At low temperature, since the solute alloying elements diffuse slower in the lattice of alloy matrix than through the grain boundary, several oxide scales could be formed on the alloys.

With increasing PC content, the combined effect of phase separation-induced crystallization and the availability of more amorphous segments can lead to an increased number of nucleation sites during solidification.
This physical hindrance by the increased number of amorphous segments disrupts the efficient packing of crystalline segments and restricts the growth of larger crystallites.
When smaller crystallites are formed, the density of the domain (grain) boundaries also increases [25,27].
More number of boundaries offer more resistance to deformation and tear.
During abrasive wear conditions, when a tear initiates within the material, more number of boundaries arrests the progression of tear and thus, makes the removal of material difficult [13,25].

For this reason, the mathematical models presented in publications [6–8] still do not allow us to identify the causes of the observed contradictions and to receive a reasoned answer to a number of key questions in the theory and practice of steel casting.
(1) The solution of the system (1) for a number of low-carbon out-of-peritectic alloys (С0≤СH or С0≥СB; С0 is the carbon content in the alloy), presented in Table 1, performed by using the POLYTHERM software package [10] to assess the joint introduction effect of basic components such as silicon, manganese, chromium and nickel within their grade content in casting steels.
Numbers 1, 2, 3 correspond to the minimum, average and maximum content of the input component - Si (a), Mn (b), Cr (c), Ni (d); the content of the remaining Xi components in the alloys corresponds to the average level (Table 1).
The separate influence of a number of alloying components (Si, Mn, Cr, Ni, etc.) on the position of critical points H, J, B, studied on the basis of thermodynamic analysis [12], is considered as additive in temperature and concentration.
