Introduction High concentrations and viscous solid wastes refer to solid-liquid two-phase wastes or byproducts with high solid content, viscosity, and fine grain size, which are produced in industry and municipal sewage treatment processes.
According to Faraday's electromagnetic induction law, the introduced voltage U is calculated by the following equation: (4) Where, S is the area of the electromagnetic induction coil, N is circle number, is the magnetic field changing rate.

Introduction This mining area is located in Guangxi province,which is located in the low mountain and hoodoo basin area,the original belongs to our country state-owned large poly metallic mine.This mining has a long history,according to the documents,it has mining method as early as the middle period of Qing dynasty,Since completed and put into operation in 1960,after nearly half a century of development, it was developed into a comprehensive state-owned enterprise.The mining has always been the backbone of the local economy industry, made a great contribution for the country's economic construction.Because the mineral resources has dried up, mining has stopped.Due to mining activities,resulted in a large number of building crack,collapse in the center of a town near the mining area.The whole town in 1969-1970 the overall relocation,the area is at a sterilize state now. 1 Geological Environmental Conditions 1.1 The Formation Lithology.The exposed layer in Mining area is Quaternary
and peak cluster valley, peripheral uplift as consisting of sandstone and shale, middle and low-lying land base for sandstone and shale, overlying limestone, terrain leads to precipitation, promoted the formation and development of the karst landform in the area, which leads to the complicated hydrogeological conditions and water filling deposit is relatively serious. in the mine ,the outdoor floor mainly for Cambrian shale and Yujiang-Rong group of Devonian limestone , the two contact unconformably. 2 Karst Development Characteristics and General Situation of Karst Collapse Development 2.1 Characteristics of Karst Development.Mining area in the plane direction of karst development and distribution is fitted with the distribution characteristics of three groups of fracture structure which distribute to north west, north east and near north-south .A set of well-developed faults along the north and south are the major elements of underground karst channel in southern mining area , form number
Due to the lower part as the permeable layer, the karst water and pore water exists at the same time. least conducive to soil layer stability is underground water level in the permeable layer, especially sharply pumping groundwater in the mining, will produce a larger dynamic water pressure and seepage pressure, when the water level reached the critical hydraulic gradient, small grain of sand will quickly transported, soil cave to form.

Glass-ceramics have a number of useful applications such as building materials, cooking ceramics, machinable ceramics, bio-ceramics, optical materials, etc.[2] Recently, the preparation of glass- ceramics from various wastes such as slags [3], coal ash [4], incinerator ash [5], waste glass and shell [6], phosphorous fertilizer and oil shale ash [7], etc has been investigated.
This may be related to the microstructure, which consists of a great number of fine Wo grains in this glass-ceramic.

X-ray analysis gave the good number of lattice parameter for Ni3Si, a = 0.3522nm, and has good agreement with index.
On the other hand, there is also possibility that the reaction will form a number of stable Ni3Si phases.
XRD analysis data of Ni plated SiC+Al powder prior to sintering V.B.V.Strong : Very broad very strong, Calculated for β-SiC, ao=0.4364 nm, Calculated for Ni, ao=0.3523 nm, Calculated for Al, ao=0.4051 nm The lines for this phase are extremely broad indicating very small grain size and/or considerable strain broadening.

Introduction The ceramic pigments with particle size in the nanoscale have a massive potential market, because of their high surface area, which assures higher surface coverage, higher number of reflectance points and hence improved scattering.
This may result in inhomogeneity, larger and uneven grains and poor control of stoichiometry [4].
One of the cheapest amino acids, glycine (NH2CH2COOH), is known to act as a complexant agent for a great number of metal ions because it contains a carboxylic acid group at one end and an amino group at the other end [13].

The method has been implemented to a number of industrial digital radiography system [4,5].
A set of multiple radiographs for a number of angles of view, namely 0o, 30o, 45o, 60o and 90o were collected.

A number of countries have also carried out international cooperation in this regard.
Fig.1 Rice straw forming process The Machanical Technology of Rice Straw's Granulation Under the developing of the thermoforming technology of biomass to today, the market has a number of different ways of forming granulation equipment, these devices have their own advantages, but the prevalence of high energy consumption, low productivity shortcomings.
In the process of granulation, the gap between the die and the roller is extremely important, if the gap is too large, it is easily to lead to skid in the mold roll and the output is low, maybe sometimes there is no grain; gap is too small, modular roller mechanical wear is serious that affect the use of life.

Humphrey and Kalu [6] have suggested that the bigger the size of the particles, the more the number of deformation zones per particle, and the bigger the rotating amount of deformation zones.
The amount of rotation in the zones and the number of zones per particle is found to increase linearly with strain.
However, because this kind of particles are fine and mainly locate at the grain boundary [5, 7], they may benefit the matrix of the MMC to obtain a more homogeneous deformation compared with that of the unreinforced material [2].

Introduction Due to the industrial development, increasing number of vehicles and manufacturing facilities add the severity of contaminant levels in atmosphere.
Gradient grams of un-treated activated carbon and AC mixture grain were put in 3 liters of tedlar gas bags, used as adsorbent for the standard BTEX gas (2L).
Detection of dust concentration was conducted in every 30 cm distance from the inlet, and in each sampling section, number of electrode were equipped in 3, 2, and 1cm interval.

Commonly, rapid cooling and crystallization of the non-equilibrium effect make a serious dendritic segregation and inside stress during solidification, which induce the significant unevenness component at grain boundaries, and those will bring adverse effect to the subsequent thermal processing [9-10].
