Without any doubt, this is very important information that temperature should play a significant role in all of these models. In the presented work, the results of studying of a heat flow distribution and calculations of temperatures of the crust of the Eastern Black Sea water area and adjoining territory are given. The distribution of a heat flow is made on the basis of the experimental data and also on the basis of the calculated flow values. Temperature calculation was performed by solving the heat equation. Study region was covered with equal-step grid and in its node bedding depths of boundary surfaces are known. The temperature calculations were performed at the nodes of the lattice at the bottom of the sedimentary complex, and at the border of Conrad and Moho. The calculations take into account the dependence of the coefficient of thermal conductivity of rocks on temperature.展开更多

Interior design originates from life, and needs to solve the problem of the material world and spiritual world. People improve the living environment and life quality through interior designs. The style of design depends on the geographical features and various cultures, which refi ects the artistic features and personality. The development history of modern architecture and interior design shows that the style of interior design is an important part of the whole architectural style, which reffects the design features of the whole building. Therefore, interior design and outdoor design should be in harmony. The orientation and characteristics of interior design determine the necessity of the style reforms. The future development trend of interior development may have the following characteristics humanism, green design, nationalization, intelligence and regionalization.展开更多
