The effect of the ratio of Mg/P on pH value is mainly that when the ratio increases, the time of the inflection point of pH value is obviously advanced, and their final pH value is close.
As an important index to affect the durability of MPC, the study on the drying shrinkage of MPC was helpful to the popularization and application of MPC in the field of Engineering repair.
At the same time, it can be seen from the curve of Fig. 5 that with the increase of the ratio of Mg/P, the time of inflection point in the rising stage is obviously advanced, that is, the reaction time of the third stage is obviously advanced.
At the same time, with the increase of the ratio of Mg/P, the time when the inflection point of the pH value occurs is obviously advanced, and the final pH value is close.

Safety is a prerequisite for chemical production of the chemical engineering, large quantities of safety resources should be invested into the chemical engineering for preventing accidents.
While many chemical raw products of the chemical engineering also are flammable, toxic, corrosive substances, so there are many danger or unsafe factors with the whole chemical engineering.
This paper will briefly discuss the innovation of advanced method for evaluating efficiency of safety resources based on information of accounting.
Requirement of Enlargement of Safety Resources in Chemical Engineering.
So the chemical engineering industry must develop persistently, steadily and healthily.

• Each of these challenges is a complex, large-scale problem to which science and technology can contribute part of the solution, yet U.S. investments in R&D have not been focused on the physical sciences and engineering, which hold the key to addressing many of the issues
• A new generation of scientists and engineers is needed to deliver the R&D from which technological solutions will be drawn, yet the number of American-born students of science and engineering at U.S. universities is falling, and fewer international students are coming to the United States to study and conduct R&D.
Progress has been made on advanced structural materials (e.g., ferritic/martensitic steels, refractory alloys, and ceramic composites).

Such “defect engineering” requires knowledge of the detailed configurations of the various kinds of dislocations as well as the origins of these configurations so that strategies might be formulated to enable control to be exerted over the processes involved.
If the advancing macrostep encounters a step advancing in the opposite direction, for example a spiral step from a screw dislocation which emerges on an adjacent terrace located in the overall downstep direction, the dislocation will be re-deflected into the threading direction as shown in Figure 4(b).Moreover, the TED segments among BPDs have been confirmed by the existence of jogs as shown above in Fig.2 (b) and (c).
At a later stage of growth, if the outcrop of the re-deflected TED encounters another advancing macrostep, the whole process can be repeated, as shown Figure 4 (b).
