Tel.: +8673 18975100970; E-mail address: yuanqingcsu@163.com Keywords: Probe; Frequency; Phase; Oscilloscope Abstract: A testing circuit of probe is designed to research the electrical properties of the probe under different loading frequencies.
Probe electrical properties will change due to continuous compression and extension of the probe in the test.
We believe that electrical properties of the probe will vary with loading frequency.
Based on experimental data, we can conclude probe electrical properties varies with loading frequency in probe testing.

Among steel types, where safety is predominantly important they occupy distinguished place for their outstanding mechanical properties.
Besides outstanding mechanical properties their good weldability must be also considered.

The results show that flow stress is significantly affected by both deformation temperature and strain rate, the flow stress increases with increase in strain rate and decreases in deformation temperature during the hot compression process.
Flow stress reflects the deformation properties and the flow stress behaviors are affected by deformation temperature, strain rates and comparative strain during hot deformation [2-4].

Among many of factors involved, the main certain factor is the most allowable interference and the minimum compute interference, the former is decided by promising strength condition of fit part material ,the later is decided by promising strength condition of linking, that is decided by delivering a burden condition.
Then each factor’s influence is considered, through necessity revise then the most interference and minimum compute interference is get.
The finite element analysis model for interference fit combination mold extrusion is established, and the cell types and material properties are determined, the combination mold interference fit problem is designed, analyzed and calculated by using ANSYS finite element software [5].
So it will not produce plastic deformation and not affect the product performance.

The conclusions point out the schemes and the optimal parameters of evaluation as well as the application limits of thermographic inspection Introduction Composite pipelines made up of glass fibres reinforced epoxy resins are increasingly used, especially in oil and gas industry, for their good mechanical properties, combined with reduced weight and excellent behaviour under hostile environment conditions.
In order to solve the differential equation of the thermal conduction in a particular situation it is necessary to know the real conditions of process development, which determine the univocity of the process: geometrical conditions, which describe the dimensions and shape of the body; physical conditions, which include the material thermal properties, initial conditions, which establish the body temperature in the initial moment, boundary conditions of first type, which establish the temperature distribution at the body surface related to time ; boundary conditions of the second type, which refer to the time variation of the thermal flux density at the heat exchange surface; and boundary conditions of the third type, which establish the manner of heat exchange between the solid material surface and the environment.
To identify the affected zone each sample was divided in some equal sectors, according the equipment field of view.

Research on Cone Angle of Cutter Head for Big Diameter Shaft  with Analysis of  Drilling Mechanics Zhenhui Luana, Lianjie Caib Mechanical Engineering school, Anhui University of Science and Technology, Huainan China azhluan@aust.edu.cn, bchildjicy@163.com Keywords: cutter head; cone angle; slurry; cuttings Abstract.
The aspect of rock breaking Since the advent of rotary drilling, rock breaking mechanism basically hasn’t change, mainly relies on mechanical resilience to break the rock[3].
Furthermore, when exerting the role of the static and dynamic load, the changing tends of the crushing mechanism, morphology, and mechanical properties of the rock are similar[4].
On the one hand, it will waste a lot of power, on the other hand, it will affect the drilling speed.
Comprehensively consider all kinds of factors, the paper suggests to select α=35°~45°, that is β=90°~110°
