Introduction
PSN have been widely used in various industrial fields because of their excellent performance, such as air penetrability, mechanical properties, abrasion resistance, mold resistance and hygiene [1, 2].
Mechanical properties were almost invariant.
Studying on feasibility and effect factors of partial hydrophilic finishing using the single factor experiments and orthogonal experiments, the results of study display that hydrophilicity and softness of nonwovens materials are optimal when the concentration of hydrophilic additive is controlled at 1% ~1.5%.
Tab.4 shows the comparison of various properties between the finished and blank sample under the optimum process conditions.
However, the slight decline does not affect the usage in the hygienic

These materials can repair and reconstruction of anterior cruciate ligament, the choice of materials involves many factors such as stability of complications after anterior cruciate ligament reconstruction and postoperative.
Allograft material preparation and preservation of anterior cruciate ligament reconstruction due to cross infection allograft transplantation may lead to disease, thorough disinfection of tendon, and may affect the physical properties to the tendon, the application is restricted.
At present, many research and clinical application of artificial synthetic material has good biocompatibility, biodegradability and absorbability, not only has good physical and mechanical properties, but also has mature processing technology.
Summary Reconstruction of the anterior cruciate ligament material alternative choice relates to the stability and the postoperative complications of multiple factors.
Synthetic materials in the relevant indicators and mechanical properties are gradually to meet the anterior cruciate ligament reconstruction conditions, but the cost is high, tendon bone healing slowly, and the reconstruction of anterior cruciate ligament long-term effect is still controversial, limit the clinical application of tissue engineered anterior cruciate ligament.

High performance concrete (HPC) is prepared with lithium-slag and fly ash,which is the industrial waste in Xinjiang Province, China, and research mechanical properties,crack resistance impermeability of concrete.
The results show that: lithium slag can well improve the mechanical properties of concrete, after adding fly ash, in the total dosage of 20%, the improving effect on the mechanical properties is the best; in the total dosage of 50%, its performance improvement of cracking resistance and impermeability is particularly evident, and can significantly improve the interface of concrete structures and products.
The test based on above study, makes lithium slag and fly ash as mixed complex of concrete, and explore the improve regularity mechanical properties, crack resistance, impermeability and microstructure of concrete after complex mixed.
These factors promote the growth of concrete strength, especially the compressive strength of concrete has been significantly improved.Therefore, the performance of high-performance concrete mixed admixture is better than single mineral admixture.
If the amount of lithium-slag and fly ash increases, the mechanical properties of HPC is not increased but decreased.

Design accuracy is assessed according to strength and deformation properties of wires a rope is made of and a rope cross-section construction is taken in account as well.
The paper presents models of ropes equally loaded which eliminates the most unfavorable factors affecting their life cycle.
The strands in the rope together with the tensile modulus in the tension of wires and Poisson's steel ratio [7] for wire ropes used are the parameters which should be assigned to the put to sleep effect of the rope strands and the rope itself including lubrication reducing the friction between the wires when the rope is working [8].There is a number of factors affecting the service life of wire ropes but one of the fundamental ones is load of a rope, strands and wires.
The bindings in the nodes 1-6 detract two degrees of freedom, one of the binding forces is affecting the tangent of the circle written by the strand.

Also, the loss in mechanical properties as compared to the base material is very significant.
These factors make the joining of these alloys by conventional welding processes unattractive.
Both of these factors influence the temperature increase within and around the stirred zone.

Introduction
Surface plastic deformation processes have become extensively used by industries to produce metallic components with superior mechanical properties.
This residual stress improves mechanical properties and fracture resistance of the treated part.
These differences have a significant impact on surface characteristics and mechanical properties.

The Methodology of the Researchs
The quality of the MAO-layer depends on many factors.
Many factors affect each other.
To determine the effect of process parameters on the properties of the coating MAO and its corrosion resistance is necessary to determine the effect of technological factors in the aggregate.
The same process factors influence the coating thickness (Eq. 4).

Dynamic vibration and static deformation are two main factors that affect the machining quality in a long slender shaft turning operation.
The mechanical parts such as the screw of machine tool, the camshaft of engine and the broach of broaching machine are typically slender shafts which play a very critical role in the mechanical structure.
Therefore, as the force-induced deformation and vibration being the major factors that affect the machining quality of a slender shaft turning, considering the forces and the constraint conditions, obtaining the direct receptance at the cutting point, building a regenerative chatter model and analyzing the effect of cutting conditions on the SLD, will have a important theoretical significance and pratical value.
As the dynamic displacement in Eq.(4) can be determined using the dynamic properties of the structures, transfer function or frequency response function, and the dynamic cutting force.
The SLD corresponding to position at x/l = 0.6 shows that it is also affected by the second modal of the beam besides the first one (at 225 Hz).
