The observations included negative air ion concentration, positive air icon concentration, wind speed, temperature and relative humidity, and negative air icon concentration in materials and plants.
The main observation contents are positive and negative ions concentration in the air, wind speed, air temperature, relative humidity, anion concentration in plants and building materials, etc.
Japanese made Ion Tester COM-3010PRO is used to test the anion concentration in plants and materials, 20 seconds for one data and take the peak number, 3 data for each test.

In addition, given a high ambient temperature, the thermal decomposition temperature of phenolic resin reaches easily, thus thermal decomposition of organic matter takes place, resulting in that phenolic resin effects on other materials of composite material significantly reduced, which have a great impact on the wear properties of composite materials.
Because the debris easily remain on the surface of materials, the dual materials re-press the minor debris into the friction surface during exercises (as shown in Figure 9) and there is a slight lower in wear rate.
