This situation makes engineering staffs hope to get a model, which can use the basic physical and mechanical properties of loess parameters to calculate the coefficient of collapsibility of loess, and which is practical and correct on theory.
The discussion of affect factors of collapsible loess Loess was incompact soil and deposited in dry and cold climates.
Only when the CaCO3 in loess as cement, it will affect the collapsibility.
Other factors, such as clay content is also the important factors influencing the collapsibility of loess, but because of it is not common parameter in engineering soil test, considering the simplification of model ,the clay content is not considered.
In addition, the loess natural density and dry density are also very important factors, but the density of loess is relate to its dry density and water content, and water content has already been considered.

In the ideal situation the welding line should keep its initial position, but due to multiple forming factors the welding line is moving during forming process.

Membrane properties were characterized by means of FT-IR, SEM and Contact Angle Meter.
The amount of HFBA had significantly effects on the film properties.
Thus, its membrane properties are greatly enhanced by this solvent-free emulsion polymerization in a single step.
Surface energy and surface roughness are the dominant factors that influence the performance of the surface property [5].

Numerical analysis on characteristics of heat transfer of pulsating flow around the vibrating tube Qian Liu1, a , Jiuyang Yu1,b, Wei Lin1,2, Lijun Liu1, Wenhao Yang1 , Yiwen Chen1 and Sihao Nie1 1 School of Electrical and Mechanical Engineering, Wuhan Institute of Technology, 693# Xiong Chu Street,Wuhan 430073, Hubei, China 2 School of Mechanical and Electrical Engineering, Wuhan University of Technology , Luoshi road 122, Wuhan 430070, Hubei, China aliuqian19870131@126.com,bjyyu@mail.wit.edu.cn Keywords: Pulsating flow; Vibration; Heat transfer enhancement.
The results showed the combined action of pulsating flow and vibration enhances the coefficient of heat transfer, and the surface heat transfer coefficient of vibrating tube increases with the increment of the tube vibration amplitude, frequency and pulsating flow amplitude, and pulsating flow frequency has less affected.
(a)pulsating flow frequency f=5Hz (b)pulsating flow amplitude A=0.012mm Fig.4 Variation of the instantaneous heat transfer coefficient when the tube under a constant vibration Discussion of heat transfer enhancement factors From Fig.5 ,we can see in a vibration period , the velocity of fluid near the tube have got obvious variation relatively, The whole circulation area still have the vortex fall away, where a is time-phase in a period.
From Fig. 6 we can see for the instantaneous surface heat transfer coefficient vibration has more affect than pulsating flow.

This approach helps in keeping a balance between material usages, build time and mechanical properties.
As the properties of cellular structure depends on its relative density, the mechanical properties of honey combs are better than lattice structures.
Therefore filling the internal structures with honeycomb structures would give better mechanical properties.
So, these cellular structure keep a balance between mechanical properties as well as the material consumption.

Nguyen and Len [3] conducted a study on the mechanical properties of AC mixtures with varying levels of sulfur modification, finding improvements in both Marshall stability and rutting resistance.
In designing durable AC pavement layers for cold regions, understanding the fracture properties of these mixtures is crucial.
For instance, Kim and El Hossein [5] were among the first to assess fracture properties using the classical concept of fracture toughness.
These factors challenge the reliability of fracture energy as the sole metric for assessing low-temperature performance.

Concerning the mechanical properties, the quenched material showed superior strength and ductility besides a less localized deformation at higher strains.
The mechanical properties of the DP steels are mainly attributed to their microstructure which consists of hard martensite islands (or in some instances bands) embedded in a ductile ferritic matrix.
Additional constituents found in DP steels are bainite, new or epitaxial ferrite and retained austenite where the amount of these constituents depends among other factors on the cooling rate of the heat treatment.
