Introduction Activated carbons (ACs) are promising electrode materials for electrochemical double-layer capacitors (EDLCs) because of their fine porous structure and stable physicochemical properties [1].
High BET surface area and the abundant mesopores made sample CA0 an excellent electrode materials for EDLC with the specific capacitance of 255 F g-1 at the current density of 1000 mA/g.
It can be concluded from the rate properties consisting with the CV profiles that: Firstly, the decrease of BET surface area and pore volume of electrode materials lead to the reduction of specific capacitance.

Most roofs on Earth are made of dark materials.
Reflective materials are also referred to as cool materials because, under the same conditions, they remain colder than standard materials due to their optical characteristics [4].

Study on The Controlling System of Particle Materials Separating Device Li Li1,a, Yongqing Gu1,b,Wei Zhang1,c,Meiying Qiao1,d,Hong Shen1,e 1Henan Institute of Science & Technology, Xinxiang 453003, China alilinhist1999@163.com,bhngyq@163.com,czhangwei@hist.edu.cn,dqmy@hist.edu.cn, eshyl99@hist.edu.cn Key Words: vibrating sieve, ultrasonic wave, controlling system Abstract: The present thesis proposes the controlling program to separate the particle materials by making use of low-frequency ultrasonic wave, and elaborates the design of system circuit controlling the ultrasonic vibrating sieve.
Introduction Separation of particle materials is an indispensable program and process of industrial manufacture.
By inputting the ultrasonic transducer, it introduces a low amplitude and high frequent ultrasonic vibrating wave onto the screen on the basis of traditional vibrating sieve for improving the screening performance of superfine Materials.
Interconnecting the 3525 chip with peripheral circuit to generate the main frequency of ultrasonic wave, enlarging the output current by power amplifying circuit and producing the additional wave by SCM(Single Chip Micyoco)for fine adjustment, the system is able to separate the materials by vibrating the screen rack which is moved by transducer.

For example, choosing either deep color or rough surface materials is helpful to building energy-conserving.
It is appropriate to select those external decorative materials with smaller coefficient to absorb solar radiation in hot areas
It is appropriate to select external decorative materials with the bigger absorption coefficient to solar radiation in cold district.
