Conceptual metaphors belong to traditional vocabulary metaphors, and ideational grammatical metaphors are pointed out by Halliday--the main representative of systemic-functional theory. This paper elaborates on the specific grammatical feature of EST （English for Science and Technology） text--＂nominalization of processes＂ to reveal the source of ideational metaphors. From the analysis of some examples, it is found that nominalization as a grammatical metaphor expresses the transference between process types, so it reveals the essence of ideational grammatical metaphors. Meanwhile, the comparison made between grammatical metaphors and vocabulary metaphors reflects the similarities between conceptual metaphors and ideational metaphors. In this way, this paper comes to the conclusion that the combination of the study methods of metaphors from both cognitive and systemic-functional perspectives is the best way to uncover the basic characteristic of human thinking.展开更多

The desired results for micromorphic continuum mechanics and couple stress theory are naturally obtained via direct transitions and reductions from the coupled conservation law of energy for micropolar continuum theory, respectively. The basic balance laws and equations for micromorphic continuum mechanics and couple stress theory are constituted by combining these results derived here and the traditional conservation laws and equations of mass and microinertia and the entropy inequality. The incomplete degrees of the former related continuum theories are clarified. Finally, some special cases are conveniently derived.展开更多

Space and time have been shown in the Unitary Quantum Theory (UQT) not to be connected one with the other, unlike in the Special Theory of Relativity. In UQT, time becomes Newtonian again, and the growth of the particle’s mass with growing speed proceeds from other considerations of physics. Unlike the quantum theory, the modern gravitation theory (the general theory of relativity) is not confirmed by experiments and needs to be considerably revised.展开更多
