Abstract: Doctoral students are the backbone of high-level innovative talents for realizing the great rejuvenation of the Chinese nation in the new era. New engineering development provides new opportunities and challenges for cultivating high-level talents. Aiming to solve the conspicuous problems facing the training of talents, the model of cultivating bachelors, masters and doctoral students continuously was put forward, and some connotations of the eight aspects about integrating bachelor's, master's and doctoral degrees were refined. This paper has optimized and designed an integrated training system that adjusts the discipline direction to the professional foundation systematically with the goal of cultivating the top demand of top-notch innovative talents, established "3+X" dynamic adjustment mechanism in line with the growth rules of top-notch innovative talents based on students' interests and abilities, built an endogenous dynamic mechanism for inspiring disciplines and scientific research resources to invest in undergraduate students, and created a "military and civilian" integration quality and ability training relying on the strength of national defense military research, based on the needs of major research projects.
