Problems solved by technology

[0002] Since the nineteenth century, countries around the world have developed thousands of energetic compounds, but due to the lack of necessary performance prediction methods before synthesis, some of the synthesized energetic compounds were abandoned due to poor performance, and some were abandoned due to Poor stability makes it impossible to apply, and there are very few energetic compounds that are actually used in weapons and equipment; The powerful support function of aided design, the synthesis of energetic compounds is time-consuming and laborious, and has a certain degree of blindness
The above factors determine that the current design and development of energetic compounds lacks innovation, and it is also difficult to meet the current needs of weapons and ammunition for new energetic compounds

[0064] Figure 4 It is a flow chart of generating a bicyclic combinatorial library of energetic compounds based on the smile chemical expression, combined as follows Figure 4 Explain its process:

[0065] Start the program, read in the text file containing the single-ring smile pattern, randomly select two smile-like strings of single-ring a and b through the loop, and randomly select two points c, d and e on ring a and ring b respectively , point f, if the atoms corresponding to the four points meet the requirements of the corresponding atom type and hybridization type, then continue to operate, otherwise return to the loop and continue to select points until the four points meet the requirements. Then if point c on ring a and point e on ring b, point d on ring a and point f on ring b respectively correspond to the same atom type, or point c on ring a and point f on ring b , point d on ring a and point e on ring b respectively correspond to the same atom type, then continu...
