The core shape is a significant factor which directly affects the eddy current signal and the sensitivity for detecting coins.
Considering the factors of decreasing interference between coils and the practical shape, the improved device configuration designed upon experiments is shown in Fig. 4.
The method based on mechanical properties, which is presented in the paper, is widely used in the improvement for the coin telephone of HT998(3)P/T.

The results show that: the distribution and morphosis of the M/A constituents have strongly effect on the mechanical properties.
However, the influence of morphological, quantity, dimension and distribution of M/A constituents exist in X80 pipeline steel on mechanical properties have not been studied systematically.
These two factors contribute the higher impact absorb energy in base metal.
Generally, the strengthening effect of constitute is dominated by three factors when the composition of constitute has been known.
(2) The M/A constituents changes in average chord and volume fraction have large effect on mechanical properties.

Recommendations for optimizing welding parameters to improve the mechanical properties of welded joints are proposed. 1 Introduction Welded structures are widely used in mechanical engineering, construction and other industries.
It is characterized by high strength, good welding properties and increased cold resistance.
In this zone, grain recrystallization and changes in mechanical properties can occur due to phase transformations and thermal effects.
These zones respond differently to applied loads, affecting stress distribution and mechanical performance.
One of the most significant factors affecting the propagation of plastic deformation is the magnitude of internal stresses that develop due to phase transformations occurring during the formation of structural components in the welded joint.

Mechanical Properties Young and Shear Moduli.
Patient age is another important physiological factor affecting fracture toughness.
The tubule orientation θ with respect the direction of load application is probably the most important factor affecting dentin fatigue behavior.
Damping is affected by many factors, in particular it increases if dentin is damaged and structural defects are present [96].

Mechanical and physical properties of a unidirectional carbon fiber reinforced epoxy matrix (T700/3234) composite have been evaluated after being vacuum thermal cycled (133~413 K, 10-3 Pa) up to 300 cycles.
It is suggested that debonding of fiber/epoxy interface and post curing in matrix during vacuum thermal cycling should be responsible for evolvement of mechanical properties of the T700/3234 composite.
This study focus in revealing the effects of vacuum thermal cycling on mechanical properties of a unidirectional carbon T700 reinforced 3234 matrix composite and its related damage mechanisms.
Mechanical properties of the T700/3234 composite before and after thermal cycling were measured using an INSTRON 8872 type material test system.

How to improve the precision of the stamping forming has been one of the stamping researchers concern in the stamping technology.This paper analysis the material stamping performance of AL5052 aluminum alloy sheet,study the influencing factors of forming precision,and find the the mapping relationship between influence factors and stamping forming to effectively predict the forming error .The first part is to analyze the factors that affect the forming process, then get the main factors that influence the part of stamping forming.
In the same cold working rate of plate, its performance curve is stable when anneal within the range of 100~260℃, and it has little effect on the mechanical properties when the holding time is 1~3h.
So the mechanical properties of the different time are also different.
The determination of input parameters: The input parameter refers to a few main factors affected the accuracy of stamping.
Through the analysis of the influence factors, find out the main influencing factors of the numerous factors, establishes the mathematical model of main influence factors, and get the error sources by training the BP neural network weights, and then to approximate the real machining process, and prove the validity of the model.

And test temperature factors on the corrosion rate of 316L stainless steel wires and mechanical properties of the most obvious effect.
Sun Shiqing et al. in hydrochloric acid corrosion of 316L stainless steel fibers were studied[2], but they did not specify 316L stainless steel wire corrosion law in Cl- environment and variation of material mechanical properties after corrosion, so this article in view of 316L stainless steel wires corrosion rate in different conditions and variation of mechanical properties after corrosion were studies, for 316L stainless steel wires applications and research provide test reference.
Fig.2 The relationship of test temperature and the average corrosion rate of 316L stainless steel wires By compared with different the concentrations of the mixed solution, different test temperature for the corrosion rate of 316L stainless steel wires, we can see that with the increase of the concentrations of the mixed solution, test temperature, the corrosion rate of 316L stainless steel wires increasing constantly, and all occurred a certain degree of passivation, among them test temperature factors become more obvious. 3.2 Analysis of 316L stainless steel wires mechanical properties As shown in Fig.3,the higher the concentrations of the mixed solution, the lower fracture strength of 316L stainless steel wires.
