The cultivation of scientific research and innovative ability is the core of postgraduate education. In this paper we presented some useful practical approaches for improving scientific research and innovative ability of graduated students. We build up the knowledge system of the students with innovative ability by means of setting up their courses and content of the courses. And the way of thinking of inventive and technology of the students is changed through some innovative programs and their thesis by consulting relevant documents, reading report, experimental designning and operating, data processing, paper writing and publication. Finally, the scientific research and innovative ability of the students will be further enhanced resulting from their independent thinking, strengthening the idea of innovation, focusing accumulation, generalization and summarization, sharing with and learn from team members, and relying on research practices.

The quantumness of Dirac particles for quantized fields in a dilatonic black hole is estimated by means of quantum channel. A general Bloch vector representation of quantum channel in black hole spacetimes beyond single mode approximation is developed. The nonclassicality of Dirac particles can be measured by the minimization of quantum coherence over all orthonormal basis sets. The quantumness of the channel decreases as the dilaton field increases. The interplay between the external reservoir noise and dilaton black hole on the dynamical behavior of quantum coherence and steerability is investigated in the Pauli basis. The external environment is modeled by a random telegraph noise channel. The monotonous decay of quantum nonlocality occurs in the weak coupling case. The degradation and revival of quantum nonlocality are observed in the strong coupling condition. It is found that quantum fluctuation effects of the external reservoir can protect quantum coherence and steerability from the information loss of the black hole.
