Cd, Pb and other heavy metals enter soil through various channels, which stay in the environment for a long time and directly or indirectly affect agricultural yield and quality.
Plant absorption and accumulation of Cd, Pb and other heavy metals are affected by many factors, such as soil moisture, texture, pH value, organic matter, organic acid, coexisting elements [2-5], and there are many studies in these aspects.
Basic physical and chemical properties of the soil are shown in Table 1.

Introduction Silicon nitride and carbide have extensively studied for structural applications due to a favorable combination of properties that include high strength, high hardness, moderate thermal conductivity, low thermal expansion coefficient, and unusual high fracture toughness.[1] These materials have been successfully demonstrated in a variety of applications, e.g., cutting tools, bearings, gas turbine engine components, and armor.[1] The understanding of mechanical properties at the microstructural level is critical for utilization and optimal design.[2] In order to investigate the microstructural effect on indentation damage behavior, Hertzian testing is preferred because it provides a tendency for brittle or quasiplastic deformation according to microstructure in brittle ceramics.[3] Several tough ceramics have been characterized with Hertzian testing method, including silicon carbide and nitride with controlled microstructure.[4] In present work, we followed
It is generally considered that the process occurring in dynamic deformation can differ significantly from static or quasistatic situations.[5] On the other hand, it is suggested that static mechanical properties are related to dynamic deformation.[6] However attempts to relate the static and dynamic damage are still insufficient.

Introduction With the development of mining subsidence research, the basic understanding was generally acknowledged by scholars at home and abroad that the geological and mining factors were the two main factors affecting the development of mining subsidence [1-4].
Currently more research results were made on the influence of various mining factors [5-6], and fewer research results were made on the influence of geologic factors in the development of mining subsidence [7].

Introduction Ti-rich TiAl intermetallic compounds have been developed as a lightweight and heat-resistance structural material due to such superior properties as high strength, decent ductility and oxidation resistance [1].
Introducing pores into Ti-rich TiAl is one way to further develop this alloy by reduction in weight and improvement of mechanical properties.
Among them, the formation of aligned pores gives anisotropy in the mechanical and physical properties of materials.
Porous intermetallic compounds often contain dendrite and grain boundaries produced during and after solidification, but their microstructures related to mechanical properties are rarely controlled during the solidification process.
Thus, we are now considering that not only the formation of directional pores but also the microstructure should be controlled to improve the mechanical properties.

Introduction Inclusions generated in steelmaking process can affect steel quality considerably [1-4].
The existence of inclusions in steel can result in a non-homogenous distribution of composition, structure and properties of steels; hence, deteriorates the mechanical properties and fatigue performance of steel products for different applications.
The installation position of EMS with respect to the copper mold in the casting facility can significantly affect the quality of cast steel.
An ideal installation site for the EMS depends on many factors, such as type of steel, cross section, length of the copper mold, immersion depth of submerged entry nozzle (SEN), meniscus position, and associated measuring sensors.
