Secondly, students search materials and discuss the assigned tasks.
Movement schematic diagram Searching Materials and Discussion Stage.
Students will search materials to implement the tasks through groups which are divided freely.
After students searched materials and discussed preliminarily, the teacher should introduce some basic knowledge and guide students normatively.

But what need to be stressed is that plastics are high molecular weight materials derived from petroleum and the average calorific value of hydrocarbon, the major component of the plastics, is as high as 40000 kJ·kg-1 [3,4].
The results are probably supposed to provide reference for the optimization of pyrolysis process parameters of waste plastics. 1 Experimental 1.1 Materials and Apparatus Experimental materials were plastic bags, transparent disposable cup and plastic film and their compositions were polyethylene, polypropylene and PVC respectively. 4 samples were PE, PP, PVC and mixed plastics whose mixing ratio of PE/PP/PVC was 6.5:2.5:1. 5 g of sample was loaded into the reactor each time.
Higher heating rate meant less time needed for reactor and materials to reach stable temperature.

Nanocrystalline Fe73.5Si13.5B9Nb3Cu1 alloy is promising materials for several practical applications such as cores in transformers and generators, magnetic heads and reactors, stress and field sensors [2-4] owing to its extremely excellent mechanical performance and high soft magnetic properties (low coercivity, high saturation magnetization and high permeability [5, 6]).
Since soft magnetic alloys often work in a wet industrial and marine atmosphere containing aggressive ions due to their numerous applications, it is important to study the corrosion response of these materials in order to compare the behavior of different crystallin states or in the different corrosion medium.
While crystallization at 650 oC fastens the materials corroion in in NaCl solution and instead decreases the corrosion rate in the blend solution of of NaCl and NaOH.

Introduction Magnetoelectric（ME）materials have attracted continuous attention due to their potential applications in the fields of sensors, actuators, and transducers.[1–4] Materials exhibiting ME effect can be classified into two classes, single-phase materials and composites.
The ME effect in a single-phase material was found too weak to be utilized for practical purpose, even at low temperature.
