The choice of similar materials and the design of mix proportions is a key step in landslide model test.
By analyzing the result of mix proportions test, We concluded the regularity that similar index varies along with different content of the similar material ingredients and found the notable influence factors , which provides important reference for the components of similar materials in the landslide model test. 1 Instruction The landslide physical model test is a direct and reliable research method in the study of landslide failure mechanism, and how to choose the similar material and its mixture is the key to the success of model test [1].
In addition, in practical engineering application, most landslides were caused by the effect of rainfall infiltration and reservoir water, so we should also take the similarity of permeability into consideration.

Synthesis of the Layered-Spinel Intergrowth Structure Cathode Materials by Co-Precipitation Method Yuchuan Feng1, a, Shixi Zhao 2, b, Cewen Nan1 and Yuanhua Lin1 1 Department of Materials Science and Engineering, State Key Lab of New Ceramics and Fine Processing, Tsinghua University, Beijing 100084, China 2 Graduate School at Shenzhen, Tsinghua University, Shenzhen 518055,China a fyc03@mails.tsinghua.edu.cn, bzhaosx@sz.tsinghua.edu.cn Keywords: Intergrowth structure; Co-precipitation method; Cathode materials Abstract.
Meanwhile the rate Li/M is also a key factor for synthesis of layered-spinel intergrowth structure cathode materials without other impurities.
Recently attempts have been made to exploit the advantages of both materials by blending both layered and spinel oxide materials [13, 14].
But these composites cathode materials were obtained by simple mix.
Meanwhile the rate Li/M is also a key factor for synthesis of layered-spinel intergrowth structure cathode materials without other impurities.

It includes the cable marked string models, materials, quantities and other information in the cable labeling string.
Calculating the engineering quantity is the basic work of preparing electric engineering drawing.
It is also the key component of budget document.
The engineering budget cost depends on two main factors: one is engineering quantities, and the other is engineering unit.
The whole system is composed of electronic engineering quota quantity extraction subsystem, cable engineering quantity extraction subsystem and engineering budget preparation subsystems.
