To study the influence of wheat straw for having concrete with improved properties, Plain Concrete (PC) properties are taken as reference.
These factors lead to the development of fiber reinforced concrete.
Tensile strength of concrete affected by uniformly dispersed and closely spaced short lengths of wire reinforcement.
Mechanical and dynamic properties of coconut fibre reinforced concrete.
Study on durability of natural fibre concrete composites using mechanical strength and microstructural properties.

During welding, a considerable amount of residual stresses is introduced due to mechanical loads, temperature gradient and phase transformations.
Thus, it is a challenge to interpret the influence of individual factors on the measured magnetic response.
For this reason, several parameters expand from the measured magnetic signals and compared to the examined material’s properties.
Interestingly, both tensile and compressive stresses coexist in the heat affected zone.
The heat affected zone was consisted by non-equiaxed coarsed ferrite grains.

As a result of these investigations, it was discovered that overdose on admixtures causes a loss of quality in concrete's physical and mechanical properties.

“Investigation of method for determining factors weights in evaluating slope stability based on rough set theory” is published by Guangyue Wang, Haili Cui and Qian Li in 2009[5].
Then, to have knowledge reduction, to delete the object with same attribute values, namely repetitive data lines, to make equivalence partitioning for discourse domain according to the condition attributes and decision attributes, after getting rid of some properties, if the change of relevant classification is bigger, it indicated that the properties importance is higher; On the other hand, it shows that the properties importance is lower.
Dump landslide is the most common occurrence and the highest frequency in dump disaster, however, there are many factors to affect the stability of dump slope, on the basis of both research results and data information from references, to select slope unit weight, cohesion, internal friction angle, slope angle, slope height, Pore pressure ratio as landslide evaluation indicators of opencast mine dump.
In terms of slope protection, we should focus on the impact of the major factors.

The integrated production process including smelting, bubble, heating, forging, prepare heat treatment, eventually heat treatment, etc, among which more than procedure is the main process of forming forging, is needed to achieve final forging shape accuracy, and to eliminate forgings inner cavity, loose and inclusions defects such as one of the important process, directly affect the quality of products [1].
Forming process using shear friction model: Where: is shear friction factor, taking 0.3, is shear yield strength.
Dynamic recrystallization the volume fraction of expression: Where: the peak strain ； Dynamic recrystallization of critical strain expression: Dynamic recrystallization grain size model: Where: is temperature compensation strain rate factor； is the dynamic recrystallization to activate, is gas constant.

Personal emotional factor will lead to bad monitor, and personal experience and ability limitation will ignore the unsafety behaviors.
One of the main measures for disaster prevention is to control the danger sources and trigged factors, including human behavior, equipment state, and field task arrangement and so on.
For affected entire mining area or greater disasters, such as: in the situation of gas explosion, working-face fire, coal-dust explosion, and the big area water gushing, emergency rescue should be immediately started.
For example, after gas explosion or mine fires, the investigation should be proceeded to avoid the recurrence of explosion: explosive properties and location, spontaneous combustion, fire, the damage of ventilation system and mine laneway, and the concentration of CO, CO2, O2 and other gases in mine atmosphere.
Some interference caused by artificial factors can be eliminated.

Linear motor can be said to be the heart of the servo valve,the quality of servo valve is directly affected by its quality.
The accuracy of test results were decreased due to some reasons, such as power supply voltage fluctuations, frequency hopping, load fluctuations and other factors can make the instrument pointer swing.
The test system was designed in this paper was used to test the permanent magnet dc motor, motor output properties, such as linear displacement, thrust and speed etc, input features such as voltage, current etc, process characteristics such as temperature, the thrust fluctuation, control precision are included.
Design of the Mechanical Structure The Whole Sssembly Drawing.
The whole assembly drawing of the mechanical structure is designed as shown in Fig.6.

The raw materials used in the study were characterized by physical-chemical and mechanical tests.
The mechanical properties were analyzed by indirect tensile strength (Brazilian Test, ITS), applying a test speed of 0.2mm / s (Shimadzu equipment) in order to establish the optimal mixture of the combinations, by determining the optimization factor (fopt) [6], on the other hand, applies the criterion of Griffith [7] for the determination of simple compressive strength to bricks and analysis according to spanish and ecuadorian regulations [13,14].
Once this process is finished, the optimization factor of the mixtures is assessed following the research criteria of García et al [6].
In the event of an increase in the plasticity index or clay content, the bond between the soil and the cement will be affected.

Equipment is the major contributor to the performance and profitability of manufacturing systems [21] Reliable manufacturing equipment has been considered as a crucial factor for competiveness [2, 6].
Products have three properties in the eyes of a customer: (Q) Quality, (C) Costs and (D) delivery lead time.
Maintenance affects all of them.
Equipment effectiveness is no longer restricted to availability, but involves other factors, such as quality and efficiency [6].

Focus on the factors causing the problem.
Retaining wall should be built 1.5 to 5 meters outside the affecting scope of the diseases caused by karst crater.
Since many factors affect the safety distance, there is no mature calculation formula.
(2) —— Safety factor，=1.1～1.5 (high class building takes a great value, other building take a small value); —— Internal friction angle of rock, (°); —— cover thickness, (m); —— stable angle of cover layer (clay is 35°～55°, sand is 35°～45°, gravel soil is 40°～55°), (°); —— Isolation width (=1~5m，high class building takes a great value，other building take a small value), (m). 4.2 Covered Volcanic Karst Subgrade Disease Treatments (1) Structures Across When the roof stability of covered karst can’t meet the requirements, the structure across treatment can be used.
When the karst crater positioned on the cutting slope is partially excavated, the crater openings will expose on the slope, the roof force will change, combined with the influence of the construction to surrounding rock structure, physical and mechanical properties, slope is easy to be instability.
