The materials of the earth construction, namely the earth, is the ideal building materials that can keep the balance of the ecological system.
Figure3, 4, 5, 6, 7 indicates that due to the better thermal stability of the adobe house's materials, namely the earth, the tested date of each parts, though there are some differences, remain the same trend of curve. the thermal bridge part of the door, window and etc. have little effect on the wall.
People around the local environment can find local building materials to build house since ancient times.
Soil and wood are two of the most eco-nature materials approved by today's ecological principles; compared with other building materials, they both have the strongest biodegradable and recyclable and the least energy consumption and pollution emissions.

Regarding the quantification of char during the processes, if a reaction is concerned with polymer materials like the former case, the pyrolysis of scrap tires, it is easy to deal with materials of low firing temperature enough to burn out.
Therefore, it is necessary to find out a solution for the separation of char from other materials and the quantitative measurement of char in their mixture with coke and others.
With increasing heat treatment of materials, the fixed carbon content of them increased coal, char and coke, in the order.
For the improvement of reliability on char content using this method, there are some points to be considered: 1) Powder size and distribution: Classification of raw materials needs.

This kind of material exhibits enhanced mechanical and several functional properties as compared to conventional coarse-grained materials [8-10].

Blickwedel and Kovacevic [9] confirmed this result for cutting different materials by injection-abrasive waterjet.
Conventional machining approaches might not always be suitable as they demand dedicated tooling to generate 3D features in such difficult-to-cut materials.
AWJ is a well utilized approach for machining Al2O3 ceramics at high material removal rate with the balance between the materials removal rate (MRR) and the level of near-surface damage.

Analysis indicates that if outside flange were enlarged to about 3.0m, not only the capacity of prestressed concrete double Tee floor slabs to bear corresponding design loading is ensured, but also the expense such as materials expense, labor cost and transportation and installation charge is reduced generally, therefore, the economic efficiency is obvious.

According to controlling geological factors of the distribution of Karst development and the concrete features of project regions disasters ,the study chose six first-class indexes to establish the risk evaluation index system[3,4], namely:formation and lithology U1(C1～C2)，geologic structure U2(C3～C4)，terrain and landform U3(C5～C7)，surface water system U4(C8～C9)，Groundwater system U5(C10～C12)，Karst development depth and tunnel design U6(C13～C14).At the same time, in terms of the investigation and studying materials, the Level 1 factor is subdivided and chose fourteen influential factors as the Level 2 discriminant index of Karst bursting water disaster risk, that is C1～C14.The specific indexes are as following: (l) The aspect of formation and lithology (U1).

Therefore, one should pay attention to the heat resistance of material when designing this part.
The temperature of point 13 that on the body is 80.2°C, in other places the temperature is lower than 100°C, and this is lower than material deformation temperature (120°C).
