Therefore it is very important to study the inner relationship between gathering energy and physical factors of medium in ultrasonic applications.
HI ultrasound acts material with unique energy forms (cavitation, mechanical, thermal, etc) and different interaction mechanism [2].
Therefore, it is hard for them to explain what conditions can promote the transferring process of biological active ingredients and what factors will destroy the medicinal properties.
Among them, amplitude of sound source (energy), speed (momentum), acceleration (impulse) and other dynamics parameters are key factors to form a transient ultrasonic cavitation.

Mechanical properties of the board showed only modulus of elasticity (MoE) met the criteria of JIS while modulus of rupture (MoR) and internal bonding were below the target.
The Tensilon RTF-1350 Universal Testing Machine (UTM) was used to evaluate the mechanical properties of particleboard, including modulus of elasticity (MOE), modulus of rupture (MOR), and internal bonding (IB).
Physical properties Density, MC, thickness swelling, and water absorption were all factors in particleboard's physical qualities.
Water absorption of the particleboard Mechanical properties Fig. 5 showed the effect of particle used to the MoE and MoR, respectively.
The properties generally fulfilled the standard excluding the viscosity.

The mechanical properties of steel plate walls are similar to a vertical bottom-fixed cantilever which vertical border elements can be regarded as flanges, while embedded steel plate as web and horizontal borders element as stiffeners.
The mechanical properties of steel plate and concrete are listed in Table 1.

The energy dissipation capability directly affects the seismic behavior of the walls.

(2) Access to the material properties: LBB assessment will use material properties and variation curve of properties.
Analysis of leak detection system should be based on the experiment and measured data of reactor, in addition, considering the impact of surface roughness, crack opening area, two-phase flow and other factors
T91 has good mechanical properties.
According to the rules, the J-integral of model under mechanical load and thermal load were calculated.
In A16 instructions, sodium leak generally choose the safety factor St=10.

During process, the mechanism of surface formation are decisively affected by a pressure force, a process time and a motion type of grains.
It has been proven, that providing the additional movements of the conditioning ring affects the profile wear of the lapping plate.
Geometrical structure of the lapped surface has good properties in sliding joints - the valleys in the surface roughness of the contacting bodies can serve as local reservoirs for lubricants [2].
Providing the additional movements of the conditioning rings may affect the profile wear on lapping plate [5, 7, 8, 11, 12].
Single- sided lapping a) main scheme, b) kinematic scheme: 1- lapping plate, 2- roller fork, 3- workpiece, 4- separator, 5- conditioning ring There are many factors which directly influence the surface flatness.

Introduction Glass ionomer cement (GIC) is a restorative material that has lower mechanical properties than resin modified glass ionomer cement (RMGIC) and composite resins.
The effort to improve the mechanical properties of dental restorative materials is always done countinuosly.
The shear bond strength was influenced by several factors such as powder to liquid ratio, hydroxyapatite particle size, surface roughness of tooth structure, conditioner and immersion time [20].
Previous research conducted by Majhool found that the addition of hydroxyapatite from fish scales can improve the mechanical properties and biocompatibility of a polymer [29].
This research is in line with the research conducted, there was an increase in mechanical properties in the form of shear bond strength in GIC and RMGIC after addition of hydroxyapatite from fish scales.

Compressive Strength Regarding mechanical properties, compressive strength of cement mortar was tested according to EN 1015-11.
The measured mechanical properties show that the average compressive strength of mortars is around 41.1 MPa (see Tab. 5 to 7 and Fig.4).
The microsilica additive had the greatest influence on the mechanical properties.
This results in a denser structure of the concrete which thus improves the mechanical properties.
At the same time, this material should have comparable mechanical properties to conventional concrete containing CEM I 42.5.

The particle size and particle distribution was strongly affected by these factors.
The common formula of the glass transition temperature is FOX: (1) Self-made cationic polymer’s Tg = 58.1℃, that copolymers at room temperature become glass transition, with a certain rigidity, which makes the film with good mechanical properties.
Fig. 4 Particle distribution of 3 # sample Fig. 5 Particle distribution of 4 # sample Affect on pH value to PCD.
At the same time, under the acidic or alkaline conditions PDEM hydrolysis could occur, this would affect their charge density.  
(3) The initiator dosage, the degree of quaternary ammonium and monomer polymerization process would affect particle distribution and particle size of the polymer.

Part of polymer phase fills capillary pores and has a major influence for final properties of the matrix.
The properties of hardened cement paste are well-known.
Improved properties in adhesion to the substrate.
Consequently, the properties of latex-modified mortar are markedly improved over conventional mortar.
The properties of fresh and hardened mortar are affected by multiplicity of factors such as polymer type, polymer-cement ratio, water-cement ratio, air content, and curing conditions [1].
