These findings indicate that controlled laminar airflow with adjustable slit angles substantially improves the properties of electrospun fiber mats.
These factors are typically categorized into ambient parameters [21-23], process parameters [24, 25], and solution parameters [26, 27].
The molecular weight and concentration of the polymer are key factors affecting the entanglement state [29].
These findings suggest that controlled airflow can help improve fiber properties, especially uniformity and defect reduction.

The ECAE process affects the material's shape memory
behavior via microstructural refinement.
Introduction Shape memory alloys (SMAs) have unique thermal and mechanical properties when deformed below their martensitic transformation temperatures.
Many experts demonstrated that these remarkable grain refinements lead to improvements in physical and mechanical properties on the as-processed materials [8].
On the other hand, solution heat treat of Ni-Ti-Pd will affect Mf the most without much change in Af (and hence reduces ∆T), as compared with the as-cast Ni-Ti-Pd.
The presence of highdensity twins in ECAE processed alloys may be a contributing factor for increases in Mf and Af and ∆T.

The chemical composition and properties of nickel-based superalloy Inconel 718 was investigated first.
Turning Inconel 718 was simulated by Deform-3D software to figure out main affection factors, and optimal combination of cutting speed, feed rate and cutting depth was introduced.
Impact of tool-chip friction factors on cutting characteristics 2) Impact of tool-chip friction factors on cutting force.
So that the impact of tool-chip friction factors on cutting force can not be ignored.
With tool-chip friction factors increases, cutting temperature becomes higher.

The interlaminar shear stress widely exists in the laminated structures of various composite materials actually [3], and its influence on the mechanical properties of composite materials is worthy of further discussion [4].
In the early stage of interlaminar shear stress research, many scholars explored and analyzed the factors influencing interlaminar shear stress through experiments.
Pagano and Pipes think that the lamination sequence along the thickness direction at a specific angle will affect the value of interlaminar shear stress, even the positive and negative [5], which is of great significance for analysis of the properties of laminates.
In order to analyze the physical factors causing the interlaminar shear stress of composite laminated structures, some scholars have studied the effects of elastic modulus, Poisson's ratio and shear modulus on the interlaminar shear stress [6].

Li et al. [7] presented a new approach to the modeling and simulation of the forces in helical end milling, where the forces are modeled by means of the predictive machining theory, and machining characteristics are predicted from fundamental work piece material properties, tool geometry and cutting conditions.
Experimental workplace and applied type of ball end milling cutter An idea of applying Taguchi designs is based on a fact that not all factors that produce variability of results can be controlled and such uncontrollable factors are referred to as noise factors.
Taguchi designs are to identify controllable factors that minimize the effect of the noise factors in experiments.
Results and their interpretation Measurement of all the components of the forces when ball end milling clearly shows that there is definite relationship between the forces as such and relevant effect of the control factors from Table 1.
Because of wide variety of factors affecting ball end milling of form surfaces, measurements were performed in milling planar surfaces.

Introduction
Steel fiber concrete is common concrete which is added with appropriate amount of randomly distributed short steel fiber, forming a multiphase, multicomponent cement-based composite material with excellent physical and mechanical properties [1].
The properties of other materials used are given in Table 1-Table 3.
Effect of matrix strength and steel fiber volume ratio on SFRC compressive strength Two factors influence compressive strength, consequently, factor A and B are defined.
As the steel fiber volume content is small, the calculation model assumes that there are no cross influence between two factors.
