Landscape planning design thoughtlessly uses traditional engineering measures of cutting off bends, stone pitching, highly building shores, etc.
Collection and register of these materials must obey the rule of comprehensive collection and focused register which takes primary source as major fully considering reliability of literal materials and forming systematic material compilation including literal tables and drawings as the basis of landscape plan design.
City is just like a person whose charms are from its unique landscape quality which depends on the social historical culture accumulation of urban geographical places and their key functionalities.
Landscape planning design of waterfront can be combined with the prevention and use of historical buildings full of regional features in order to lead waterfront landscape to keep cultural connotations and national characters of its city and to become center of environment quality which not only raises cultural atmosphere of waterfront but also increases tourist materials and strengthens its attraction.

Preparation of NASICON disk by tape casting and its CO2 sensing properties Jianguo Li, Xishuang Lianga, Chengguo Yin, Fengmin Liu, Geyu Lu State Key Laboratory on Integrated Optoelectronics Jilin University Region and College of Electronic Science and Engineering, Changchun, PR China aliangxs@jlu.edu.cn Keywords: NASICON, Tape casting, CO2 sensor Abstract.
NASICON was firstly suggested as solid electrolyte material for Na+ ion-based batteries [4].
Generally, conductivity of NASICON materials obeys the Arrhenius law, which can be expressed as follows: sT =s0 exp (-Ea / kBT)

A tire is made of several layers of different materials bonded physically or chemically [2].
A peeling test is used for determining the force needed for separating two adhesive bonded materials [12].
This research tries to reduce the total time required only for vulcanization or curing time which is considered a key factor.

One of the promising approaches is use of nanomaterials, such as carbon nanotubes (CNTs), as gas-sensing material because of their large effective surface area and unique electronic properties [5-8].
Therefore, the treatment of MWCNTs in prior to sensor fabrication would be a key approach for fabrication of benzene sensor with improved performance.
