Hartman indicated that the multiple-channel theory, involving at least two of the channels under consideration here, increases learners' language comprehension. 2 Nowadays the use of the multimedia materials is extensive and prevailing in education, as well as in recreation and communication.
These materials can give the impetus to previously passive students who might now be more attracted to learning and therefore pay more attention to classroom learning.

In production practice, once the original schedule is established many preparations must have been made, such as ordering raw materials, tooling the equipment, organizing the workforce and fixing customer delivery dates [9].
Any changes on the original schedule would cause conflicts with the upper production plan and additional troubles and costs on the preparation of materials.

When it works, the bending side of the spring spines (clockwise) close to the ground pick up the forage objects from the ground and take them to the plate, the feeding wheel(grass feed up) will continue to feed them to the front roller through its outer teethes, the rollers( clockwise) lead the materials to the inside of the shell.
At first, because the forage object quantity is small, the material inside the shell is locating basically on the two rollers and do rotating ovement, along with the continuous input of material and the dragging in, occlusion between the material, and pile pushing role, the bundle diameter is growing, the moving material flow is continuously engaged in the forage bundle under the leadership of the rotating rollers and pressing action of gravity and rotation of the forage bundle, when the bundle diameter increases to a certain degree, the number of roller direct contacting with the forage bundle is constantly increasing, under the common driving action of these rollers , the forage bundle is constantly rotating (its movement speed could be increased), so the forage material body will form a continuous movement, until the bundle diameter is large enough, so that most of the roller contact with it, through the force sensing device, the shell cover will be opened by the bundle, and the bundle
Suppose the thickness of the feeding material flow is , feeding velocity is , the mass body density is , the length of the bundle is , at some preliminary instant , the diameter of the bundle is , the diameter of the bundle at arbitrary instant is , then the moment of inertia of the bundle can be expressed as follow:

Valid reclaim technology of oil and the research and development of decontaminated materials for oil-in-water wastewater have attracted more and more attention [1-3].
It is a kind of material which can directly absorb toluene without the affect of water.
So, this composite was a kind of modified material for wastewater treatment.

The toluene retention is another important predictor for absorption material.
The availability of absorption material is dependent on it.
