According to GB/T 229-2007 Metallic Materials - Charpy Pendulum Impact Test Method, the impact specimens were cut from the weld bead, with the standard size 55mm×10mm×10mm.
Under the same condition of experiment, the bigger the proportion of fiber area and shear lips, the better of the material’s toughness.

Welding thermal simulation experiment on SMA490BW material [J].

Consequently, they were widespread used as modified RAC materials at present[3,4].
Material Tests The materials used were Ordinary Portland Cement ,river sand, natural crushed stone, potable water of Xi’an.
The age of concrete at the model test day and material test day were 28 days respectively.
Due to the discreteness of concrete materials and the process of producting or loading of the human influence, we made some results comparatively large difference, such as making the experimental value of 14% lower than the actual value.

Furthermore, the addition of small amounts of Al and Si constituents to the nanocomposite structure of these materials considerably improved their tribological and anti-corrosive properties at operating temperatures exceeding 400 °C, such as hardness and wear resistance, thermal stability, and denitrification temperatures [4].
For bulk materials, e.g., as the steel substrate Meyer’s index is a good measure of the indentation size effect (ISE) [9].
Conversely, n>2 represents so-called reverse ISE behavior, whereas at n=2 the ISE is absent for the given material at the applied indentation depths.

Lost circulation materials like one-way pressure sealant and superfine calcium carbonate were used to stop the leakage.
The Recommended practice for laboratory testing of bridging materials for drilling fluids (SY/T5840-2007) does not consider formation pressure when examining sealing capacity of plugging materials, so we added backpressure of 0.5MPa to simulate the pressure of low-pressure leakage zone in order to better reflect the bearing capacity of fuzzy ball pad fluid.
(2) Cementing operation was a one-time success, which not only reduced the cost directly, but also decreased the formation damage by minimizing the leaking of cementing materials into the formation, so the oil/gas production may be improved and the reservoir stimulation cost may be cut

Introduction In general, three types of electroactive materials are used as electrode materials for electrochemical capacitor applications, which include carbon, transition/noble metal oxide and conducting polymer.
Thus TiO2RuO2 nanotubular composite can act well as a novel supercapacitor material for effective charge storage.
RuO2 is usually regarded as the most suitable material for a supercapacitor application.

The purpose of training steps is to make teachers participating in the study realize and design the teaching materials with virtual 3D models.
According to relevant documents, the demonstration of multimedia information can effectively elevate users’ desire to learn; therefore, the design and application of multimedia teaching materials grow into a profitable instrument in the aspect of education.
However, related references indicate the sources are so complicate that users have difficulty receiving the information when performing multimedia teaching materials.
The animated design of virtual space usually makes use of maze games to do the research about the spatial concepts of children and the main element of virtual labyrinth, no matter there are references and guidance materials or not.
This design of teaching materials offers both teachers and students a novel learning method of spatial sense.

The purpose of this study is to evaluate either it is feasible to create an MDF that complies with the current standard using young rubberwood in order to compensate the current shortage of raw materials in MDF industries.
Materials and Methods The planting location for this clone series of rubber tree is determined, at latitude N5o and longitude E112oE which has average of rain is about 4000 mm a year.
The amount of fibre and the amount E1-grade urea formaldehyde resin for each board were calculated based on the oven dry weight of the fibre materials.
