In addition, the study analyzed the scope of application of
nitrogen adsorption isotherm method on investigating pore structure of cement paste.
Introduction Hardened cement paste is composite system of complex structure of heterogeneous, multiphase (gas phase, liquid phase and solid phase) and multilevel (micro, meso, and macro), and what shows on macroscopic, such as scrambling, uncertainty, fuzziness and nonlinear, etc, just are reflect of complexity of micro structure.
Pore structure is one of most important research fields for cementitious material on microscopic level.

The foam structure is also worth investigating from engineering viewpoint, because the unique feature in space-filling structure can be applicable for various purposes [2,3].
This process is quite complicated incorporating various fields of sciences, such as fluid mechanics, thermodynamics, chemistry, rheology, surface science and so on, and hence is difficult to theoretically clarify the mechanism.
Foam structure is assumed to be constructed in the following steps.
Once the foam structure is generated, it does not last long.
Summary Foam structure formation and destruction processes are simulated for two types of additional terms in the conventional multi-phase-field model, and intended types of foam structures were obtained; In Type 1, the cell size was kept the initial cell size and the foam structure with various sizes of cells were obtained.

System architecture
System Structure.
The system structure mainly consists of sensing modules, terminal units, and controlled equipment, as shown in figure 1.
Through this control, MOF can be heated and synthesized to the most ideal crystal structure.

Fig. 1 Chemical structure of Reactive Red K-2G
Preparation of Catalyst.
The degradation of Reactive Red K-2G was analyzed by UV-3010 UV-Vis spectroscopy to identify the structure change of aromatic groups in molecules.
This implied that the conjugated azo linkage and aromatic structure in dye molecules were destroyed under the catalysis of FePcS-F.
That was due to the degradation of azo linkage ahead of aromatic structure, and it implied that higher concentration of FePcS-F was favourable for the cleavage of azo linkage.
UV-vis spectra proved that FePcS-F can catalyze the decomposition of azo linkage and aromatic structure in Reactive Red K-2G, and the higher Fe ion concentration promotes the decomposition of azo linkage in dye molecules.

Since using UFDM to make APM from natural macromolecules was rarely reported, we try to make APMs from some natural macromolecules by UFDM and adjust their porous structure.
When carboxymethyl cellulose (CMC) was added into CSt paste, it could glue corn starch granules to form a film, which forms the walls of the micropores to support the porous structure.
Beside the material properties, the characteristic of natural biomaterial solution also has a profound effect on the pore structure of the APM.
The characteristics of natural macromolecules and the high porosity of porous structure make these APMs potentially used in the chemical engineering, bioseparation, biomedical engineering and environmental protection.

Therefore, we speculate that whether the structure of the BmPBP1 is gender-dependent for the differences in recognizing sex pheromone and results in the behavioral difference during seeking and mating between male and female moths.

Results and Discussion
Interaction of PI with highly energetic particles will modify its chemical structure.
The radical signal obtained from pristine polyimide suggests that any "inherent“ radical sites are localized around the central aromatic ring of the imide structure in the polymer (left side of Figure 2), while the electron-induced radicals appear to have multiple different structures.

RSM (Response Surface Methods) is put forward to optimize the structure parameters so as to improve the separation efficiency.
It is a kind of optimization method, which defines the system response (for example, the extraction rate in extraction chemistry) as the function of one or many factors (e.g., the concentration of extraction agent, its acidity, etc.).
The structure parameters taken into account in simulation are cold intermediary exit diameter D1 and lubricant going-back diameter D2.
This method would provide valuable reference to separation cavity structure designing.
The numerical simulation research of effects of interior structures deformation on characteristic of cyclone separator(in Chinese)[D].
