Around the wave number of 3000, peanut oil has strong emission, while waste oil has almost no emission.
Yuan-yang, "Status in detection technology of the waste edible oil mixed in edible oil," Grain and Oil, 2009, 4: 35-37

(2) where N = number of pixels contained in area of interest = optical density of individual pixels = intensity of reflected light given by individual pixels = intensity of light that would be reflected by an ideal white surface The experiment on a three-phase (air-water-LNAPL) system requires two cameras with two different band-pass filters (wavelengths λ = i and j) and the relationship between AOD and water satuaration (Sw) and LNAPL saturation (So) can be obtained as shown in Eq. (3).

The number of solid waste generated in Kuala Lumpur state in the year 2010 was recorded of 2000 tons per day [1].
There are three distinct processes that involve for the nucleation and the crystalline growth processes which are the primary recrystallization, grain growth, and secondary recrystallization.

A tree data structure is used for classification and prediction, the structure mainly consists of nodes from the top downward, wherein each intermediate node represents an attribute of a test, the test result is representative of each side, and each leaf node represents a classification result, the decision tree is a combination of a set of decision rules of whole grain.
Consider the process of decision tree contribution, the results can also be generated by the treee composed of property value, which is also available in a number of decision rules generated by the decision tree to provide a reference for the tournament.

The green oily liquid was added the absolute alcohol for several times repeatedly, it turned into fine grained shapes finally and kept in a vacuum desiccator.
And the conductivity of the compound depends on the number of water molecules.

In this way, many common thermal spraying problems can be effectively reduced and eliminated, like oxidation, phase change, ingredients change, grain growth[5-10].
The figure 5 (b) shows that, in dry friction condition, the grinding mark in the coating material surface has obvious furrows, and there are a large number of slices of spalling pit.

For example, different densities, grain compositions, and sand saturation exhibit different characteristics in response to explosions.
(1) (2) (3) where ΔPm is the overpressure from the explosion, R is the distance from the explosion, and Q is the number of explosives.

The blue oily liquid was added the absolute alcohol for several times repeatedly, it turned into fine grained shapes finally and kept in a vacuum desiccator.
And the conductivity of the compound depends on the number of water molecules.

With the number and size of the pores increased, the bending strength of ceramic cores will decrease.
Mullite fiber during 1540℃ high temperature strength test showed a certain amount of shrinkage, which was due to fiber internal grain grew up obviously, shown as Fig.5.

Type of Concrete Mixes (1) Natural group (N): virgin sand and stone were used as coarse and fine aggregates, respectively; (2) Waste concrete as recycled aggregate from construction sites (Waste Concrete, WC, Figure 1): waste concrete from construction sites was crushed as recycled concrete grains to replace virgin coarse aggregates.
The plan serial number is NSC 94-2211-E-166-007.
