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).

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).

Many companies have developed the functions of collecting, filtering, storage,lifting, permeability, controlling,monitoring equipment and a series of stereotypes products, and has built the engineering by more rain.
The present situation of our country, rainwater reuse technology is gradually with the international advanced technology in the world, but the operation and management experience of the corresponding need further strengthen. 2 System analysis of rainwater reuse 2.1 Quality of rainwater and rainwater control In the system of rainwater reuse, one of the important part is the quality analysis.
After the initial rainwater drainage, water pollutants will decline less dissolved oxygen, organic pollutants, close to saturation, the calcium content is low, small, total hardness, bacterial and viral contamination rate is low.So after simple treatment can be used as miscellaneous domestic water and industrial water. 2.2 Rainwater collection Rainwater reuse is a system engineering,it needs first rainwater collection.
Now some of rainwater treatment and utilization technology are not matured enough, in the actual application process will encounter many difficulties, but with the further development of the field of scientific research and engineering technology, city rainwater utilization will embark on the road of sustainable development, to maximize the use of rainwater resources is our unremitting efforts to the goal.
