The heat and mass balance of non-conventional solid material requires a physical properties model suitable to simulate it.
The reason may lie in the fact that our sample have small amount of fixed carbon unlike a biomass material or coal.
This indicates that DRS have a higher caloric value than the biomass material.

Prediction of performance of a downdraft gasifier using equilibrium modeling for different biomass materials.

The marginal difference between Al99,5 and DC04 can be traced back to the difference in strength of both materials.
The compressibility of a material affects the volume of plastic required [12].
A qualitative symmetric distribution of thinning in both materials could easily be identified in the first instance.

As a promising processing technique, the assistance of ultrasonic vibration is introduced into the high-efficiency machining of hard and brittle materials.
This method permits ultra-precision optical surfaces to be created on these difficult-to-cut materials with minimal subsurface damage [2, 3].
Once a depth of cut is given to the workpiece by lowering the grinding wheel down and a feed rate of Vf is provided to the worktable, the grinding wheel rotating at a speed of ng will interfere with the workpiece to remove the work materials.

) [9]. the authors think that the biological fuels will take no-food materials as primary resource with low cost.
This article firstly ruled out to biofuel car because of the importance of lack of the food raw material and food security .To combine the three aspects of the multi-dimensional evaluating system ,the author thinks the new energy vehicles industry should focus on the oil, pure electric vehicles and biofuels (not the food raw material), natural gas cars in the short term .

The materials which are used in fuel cells should have high proton conduction in order to get high voltage.
Hence more researchers are focussed on developing proton conducting materials.
In aliphatic PEM addition of cross-linking structure and inorganic materials would rise the thermal stability [15,16].
Accordingly, the PEM with positive and negatively charged groups are carried by the inorganic materials.

These operations involve machining aero-structural components that are comprised of different materials, resulting in what is known as a hybrid joint.
Fig. 3 (a) shows a bar chart of the cutting times of five different sample tools for various materials.
In some cases, certain materials can be repeated along a hole, making them the ones containing more width drilled.
Additionally, titanium has the lowest cutting length, even though it has the highest accumulated cutting time among the materials considered.
