Some teaching materials combine these two parts together[1] and others describe them separately in two parts [2] [3], but there are no substantial differences.
Since the first international seminar on geo-environmental engineering was held in 1986, geo-environmental engineering has generated two important branches: geological and environmental engineering, and ecological and environmental engineering.
This is the key reason why theoretical equations cannot accurately describe the mechanical behaviors of soil. 3.3 Profound Understanding of Complexity of Soil In teaching the “Preface”, we shall lead students to understand the following: soil is formed in an extremely long geological period and very complex geological environment, and it is not an artificial material but is a product in natural and historical development that has very complex properties and is not the same as any other material in civil engineering
(1) Well-mastering the knowledge of soil mechanics, engineering geology, and engineering applied soil mechanics

Simulation Study on Ultrasonic Lapping Trajectory of Ceramic Materials Changjuan Zhang1, a, Baobin Gao2, Chuanshao Liu1 and Bo Zhao1 1School of Mechanical and Power Engineering,Henan Polytechnic University,Henan,454000, China 2School of Safety Science and Engineering, Henan Polytechnic University, Henan, 454000, China azhangcj@hpu.edu.cn Keywords: Hard brittle materials, Ultrasonic lapping, Lapping track, Simulation Abstract.
Hard brittle materials have been popular used in manufacture experience because of the excellent performances.
In the paper, on the base of common lapping, ultrasonic vibration was adopted to realize the ultraprecision machining of hard-brittle materials, the lapping tracks of ultrasonic lapping and common lapping with different lapping parameters were simulated, which have some significance to guide the production practice for the engineering ceramics parts meeting the requirements of precision, surface roughness and material properties.

• Each of these challenges is a complex, large-scale problem to which science and technology can contribute part of the solution, yet U.S. investments in R&D have not been focused on the physical sciences and engineering, which hold the key to addressing many of the issues
• A new generation of scientists and engineers is needed to deliver the R&D from which technological solutions will be drawn, yet the number of American-born students of science and engineering at U.S. universities is falling, and fewer international students are coming to the United States to study and conduct R&D.
Thus, materials research is an area in which scientific advances could have a key impact on future energy security." [6] Expanding on this theme, Smalley [7] made a convincing case for abundant, low-cost, clean energy as the key to the major challenges facing humanity, observing that "innovations in nanotechnology and other advances in materials sciences would make it possible to transform our vision of plentiful, low-cost energy into a reality."
In each of these areas, materials R&D is key; the plan reviews current research portfolios, which include a wide variety of materials science and technology, and calls for further materials R&D in virtually every discussion of future research directions.
