The DSC-TGA curves showed that the main exothermic peak was at 479°C and the total mass loss was 79.2%.
The porosity was calculated by equation 1.
DSC/ TGA curves of the dried gel were shown in Fig.1.
The results (table 1) show that the setting time of CSC when L/P=1.0 was longer than that of when L/P=0.9.

We calculated the main quantitative characteristics of the interdisciplinary connections [1], which subsequently allowed to establish a hierarchy of physical concepts in the course of chemistry. 1.
For example, the concepts of atom and substances have the same meaning of L = 1.

The schematic of the hybrid structure is shown in Fig.1.
The total composite wall is named as substructure 1, and the total shear wall is named as substructure 2.
According to Timoshenko beam theory [5] (Timoshenko 1990), the relation equations among the shear deformation, the flexural deformation and external horizontal loads of substructure 1 are introduced as (1) (2) To substructure 2, the relation equation between the flexural deformation and external horizontal loads is introduced as (3) where G1A1 and E1I1 is the shear stiffness and the flexural stiffness of the substructure 1; E2I2 is the flexural stiffness of the substructure 2; q(x) is the interaction between substructure 1 and substructure 2.
Combining Eq. (1) with Eq. (11), yq1 can be derived as (11) Based on the prior assumption, yb2=yb1+yq1, and y=yb2.
