Stabilization is a method used to modify soil properties by application of chemical, biological, or mechanical means for the suitability and attainment of a specific engineering purpose [3].
In the choice of selecting the appropriate stabilizer to be used, different factors determine the type of stabilizer to be used in ensuring the properties of the soil are raised for the intended purpose.
These factors may include soil type, the nature of construction work, and the accessibility of the materials used in the construction [6].

The energy needed to recycle the solvent and the properties of the final product are all need to be considered.
Printing ink affects the environment greatly, which is the most serious pollution in printing industry.
What’s more, they would form oxide and photochemical smog pollute atmosphere under the irradiation of sunlight, which seriously affects people’s health and the quality of the environment.
The pH value, temperature, humidity, enzyme, osmotic pressure and other factors influence the symbiotic net structure and effective microbial activity.
The economical benefit would be affected even causing improved production cost when the ink pollution of other source of pollution occurred to this kind of equipments.

The properties and distribution of these aerofoil shapes are listed in Table 1.
Some small alternations have been made to the tip region which do not affect the power coefficients so much but would reduce thrusts at high winds.

Considering the weight factor, thickness of layups rapidly declined in the direction from root to tip, which results in local strain discontinuous areas.

Their practical use requires the following properties: avoiding short-circuits between neighboring wires, producing a minimum of toxic gases and dark smoke during pyrolysis, and keeping good mechanical properties.
Since Mg 2+ and Al3+ are distributed in these octahedral structure spaces randomly and form the positively charged basic layer, the doping of Sr 2+ affects this kind of distribution of Mg 2+ and Al3+ in the octahedral structure spaces.
Consequently, the hydroxyl in this kind of hydrotalcite basic layer is likely to produce much slighter displacement of the negative ion O 2 so as to satisfy the balance of the electronic valence, which affects the bond combining and distance between the basic layer [Mg6-xSrxAl2(OH)16] 2+ and the middle layer [CO32+4H2O]2.

Introduction Nitrogen as an alloying element has several beneficial effects on mechanical properties of steels, especially related to an excellent combination of high yield strength and good fracture toughness [1,2].
Precipitation behavior of austenitic HNS has been studied mainly focusing on (i) the effect of nitrogen addition on the precipitation of the second phases [4], and (ii) the precipitation of Cr2N [5], together with its detrimental effects on properties of HNS [1].
Therefore, it can be deduced that the Cr2N precipitation did not affect the orientation rotation during deformation.
It is known that the deformation twinning in f.c.c. materials is generated by the combined movement of partial dislocations on }111{ plane and, thus, the dissociation of perfect dislocation is a controlling factor [3,7].
The Cr2N precipitation did not affect the orientation rotation during deformation. 3.

The sulfates in the complex activator could stimulate the activity and promote hydration of cement and fly ash had significant effected in the early time[4].However,joined too much will affect the strength of the cementing material.Actually,1.5% of complex activator could be added.The proper proportion was that the content of Cement,Fly ash,silica fume and complex activator was78.5%,12%,8%and1.5%.According to the proper proportion ,the mechanical property of cementing material were shown in Table 5.

The cement based material is usually used in combination with steel reinforcement, so its alkality will inevitably affect the rate and degree of corrosion for the steel reinforcement, meanwhile, high alkality is a necessary condition for chemical stability of its hydration product.

Clinker quality, power economy and environmental load- Influencing factors and adaptation of the burning process Part II "Experience in actual practice".

Different factors like area/volume relationships, initial water content, granulometry (clay particle size) the formed body, and air-drying condition (temperature, relative humidity and flow rate) influence shrinkage.
These defects range from visible defects (such as cracks) to a reduction in physical properties in fired clay products in areas such as strength, elastic modulus, color and appearance (discoloration due to summing) [3].
However, this may give rise to high temperatures and gradients in the solid, which would induce thermal, hydrical and mechanical stresses.
The mechanical behavior of clay is generally described as elastic viscosity and plasticity depending on the moisture content.
For the other side, the drying rate can also be affected by the shape of the brick.

Introduction With the improvement of the voltage transmission level, GIS Switchgear is gradually popular for its compact, small footprint, being not affected by the external environment, high reliability, long maintenance cycle, etc[1].
As the questions of the insulation material defects and installation process failure in the process of GIS manufacture and the factors of the overvoltage infringement and the GIS internal overheating in the running of GIS under 1000kV influence, which results in GIS produces inside burr, free metal particles, defective insulation and other issues, so that the GIS partial discharge is generated that leads to insulation fault of GIS, which reduces the service life of GIS [2,3].In all kinds of GIS failure, insulation failure accounts for a large proportion, partial discharge is an important parameter reflecting insulation properties of GIS equipment.So through the GIS partial discharge detection, we can find the internal defects in the GIS timely and effectively, thus avoid a major accident.The common detection methods of partial discharge include: optical detection, chemical detection, acoustic detection, pulse current detection method and UHF detection method.This article analyzes the operational
The frequency of acoustic waves produced by partial discharge and mechanical vibration caused by metal filing hitting against the shell ranges between thousands and tens of thousands of Hertz, to remove interference from other sound sources, the 1~20kHz frequency detection sensor is generally selected
The disadvantage is that in addition to the partial discharge on site, there are many factors that may cause the vibration of the shell, and any of the vibration is very intense, however, different vibration frequency characteristics caused by different reasons, band-pass filter may be used to reduce the external impact
Charged running with long time, because of during the production process the conductor surface sporadic sharp burrs or mixed foreign particles, otherwise the electrical, thermal, chemical and mechanical stress combine effect, causing resin localized cracking and gradually developed, which will eventually lead throughout the discharge breakdown, pot burst, causing power outages occur.
