From the micro morphology of Figure 8, there were a small amount of Ca(OH)2 crystals, and a large number of hydrated calcium silicate gel flocculation.

The microstructures of the sintered samples presented second-phase particles and some residual pores at the AlN grain-boundaries (Fig. 1).
The arrows indicate YAG phase and the number 2 in (b) indicates SA6 phase.
The numbers in (b) indicate the regions of EDS analysis (see comments in the text).

The Knoop hardness numbers and the proportion of (gFe) to (aFe) in the subsurface layer were evaluated during preparation of the metallographic specimens on surfaces ground on SiC #220 paper and again after final polishing with 1 mm diamond (Table 3).

The metallographic observations (Figs 3-5) reveal marked differences in grain size and microstructural inhomogeneity of the tested specimens.

A number of improvements were developed based on the two methods, such as Doyle equation[4], Freeman–Carroll equation[5], Ozawa equation[6], Coats and Redfern equation[7] and so on.
The sawdust was screened in a vibratory sieving apparatus and the 100 mesh(grain diameter <0.15mm) fractions were used in experiments.
(3) where, i is the sequence number of the data derived from the TG curves.

This procedure was repeated for the desired number of cycles to form TiO2multilayeredfilms.
From the FESEM image, The surface of the films is composed of tiny grains without obvious void.
An obvious increasing of the transmittance could be observed atca.250 nm as the layer number increased.

Geological disasters caused by coal mining Coal mining subsidence induce the large number of landslides, slope instability, debris flows and other natural disasters.
The mode above, with the characteristic of low-cost reclamation, short payback period and significant economic benefits, is applicable to the coal mining subsidence area with ponding generated by collapse which takes full advantage of the water resources from the mining subsidence. 2) As the same time, we can the ecological environment quality in the area of mining can be improved through planning ecological garden, constructing mining museum and matched recreational facilities, and developing eco-cultural tourism in the subsidence area with large water surface, deep water body, and excellent water quality. 3.2 The agriculture, forestry, animal husbandry and fishery mode. 1)The mode that backfilling or grouting complex soil in subsidence area with gangue can change original subsidence area to agricultural land and effectively replenish the arable land is widely used in the area with a large number of coal gangue , river sediment surrounding.
This mode not only contributes to grain production, but also effectively reduces the compensation pressure and deal with the plight of the coal gangue and fly ash.

Traditional fit is defined as five factors: line, grain, ease, set and balance [11].
Clothing comfort is influenced by a number of factors, such as thermal aspects, ease of movement, fit, pressure of the body, tactility and propensity to generate static electricity [16].
It needs a large number of measurement, experiences and tests.

Traditional tile and thatch slope roof were replaced by flat roof, that is convenient to dry grains, but the heat insulation effect is reduced.
Thus the villagers can afford to rebuild their houses and a large number of old buildings were removed, the traditional timber buildings were seldom kept.

In plasma nitriding process as reported by Negm [3], there are a number of contrary opinions for adding hydrogen in nitriding process.
Besides, the XRD results is also shown a wurtzite AlN (a = 3.11 Ao, c = 4.98 Ao) formed on the top surface of the specimen (according to diffraction patterns of Wurtzite-type AlN JCPDS number 075-1620).
Therefore, it is indicated that the grain sizes are decreased due to the increasing percentage of hydrogen.

What is important is that the large grains are of low sp 3 content and low hardness.
This suggests that the structure of DLC film structure have no relations to substrates as expected. 800 1000 1200 1400 1600 1800 2000 0 500 1000 1500 2000 Intensity Wave Number (cm-1) a ID/IG=0.76 figure 3, Raman spectra of DLC films on all the substrates, and the spectra been deconvoluted to two bands between the wave number 1000 cm -1 and 1800cm -1. 4.
