The models are trained with real data, so that the DT can predict the behavior of the production process under changing conditions of ongoing processes, machines or materials, and optimal operating conditions can be predicted.
The key aspects are related not only with the composition and hardness of the material, but also with the high geometric precision of the product [1, 2].
Machine Learning (ML) is receiving great attention in science and technology research and is already playing a fundamental role in the digitization of production towards Industry 4.0.

Alternatively, polymer-covered magnetic particles can be produced by in situ precipitation of magnetic materials in the presence of a polymer that acts as a stabilizer.
SEM offers better information on particle shape, especially for coarser materials.
Paramagnetic substances and superparamagnetic and ferromagnetic materials have been used as MRI contrast agents because paramagnetic substances have a net positive magnetic susceptibility, while superparamagnetic and ferromagnetic materials have very large net positive magnetic susceptibilities since these materials become magnetized in the presence of an external magnetic field.

Multimedia teaching method is remarkable for its rich teaching content , vigorous style.it enhanced teaching standard by pictures and texts, sound and body, vividness and directness ,science and accuracy.
Here, what need special pointed out and special advocates is that teachers should be more aimed at the actual needs of the teaching content, teaching materials of specific characteristics and students' practical psychology then design psychological health education software themselves.
In learning, memory and other issues’ study, the use of computer multimedia teaching techniques, showing a vivid picture with image and sound, overcoming the a single, rigid, distortion of the experimental materials limitation, guarantee the best experimental techniques for the further study of real life events and other psychological processes of learning and memory beyond the dull boring characters the of artificial designed words and table.

Such as Mexico the rock surface natural impermeable to water the United States set; using chemical materials to increase the efficiency of water treatment in water.
With the development of society, the progress of science and technology, people gradually realizes the rainwater reuse can improve the natural water cycle, also construction operation pressure to improve the city's ecological environment of city flood disaster, alleviate the impact load of sewage treatment plants , because of excessive exploitation of groundwater caused by control the city ground down trend, to prevent seawater intrusion underground aquifer[3].
It is first chooses the permeable pavement materials and drainage ditch, rain water into river or water storage facilities, and the drainage ditch is arranged on the pebbles, contamination of surface runoff in the leaves and large particles were preliminary removal.3)We set the pervious pipe water catchment facilities in green space.

Research on Heritage Values of Industrial Buildings of Xi’an in the First Five-year Plan Period (1953-1957) Yi Xiao 1, 2,a * , Yunying Ren 1,b ,Shuhu Liu 1,3,c 1School of Architecture, Xi’an University of Architecture & Technology, Xi'an, China, 710055 2 School of Architecture, Henan University of Science & Technology, Luoyang, China, 471023 3 College of Architecture, Fuzhou University, Fuzhou, China, 350108 axyhaust@163.com, brenyunying@126.com, c lsh1200@qq.com Keywords: industrial building; the First Five-year Plan Period; heritage value Abstract.
The Xi'an modern industrial building reflects the industrial building development of Chinese interior general cities in modern times, meanwhile it is an important chain link in the history of Chinese architecture and the material testimony of Xi'an modern architecture development, so research on it has great value and significance [4].The Xi’an industrial building, as an indispensable part of Chinese industrial heritage and an organic composition of Xi’an modern city's appearance, its historical and cultural value has been realized by people, and research on it becomes more and more deeply.
Therefore, these industrial buildings are the material testimony of history influenced by multi-culture.
Finally, the material and structure or special construction method of some industrial buildings may have the technological research value in architectural history.

Study on Concrete's Temperature Control Measures for Inverted-Siphons in Wenxian-Boai.section Yi He1, Xiao-mei Dong1, Chen-hui ZHENG2 1Luoyang institute of science & technology , Luoyang.China 2The 4th Engineering Co Ltd.
Through establishing models with the thermal and mechanical properties and taking the calculation method in simulating the non-steady temperature field and stress field of limited units, detailed numerical simulation method is carried out to calculate the construction process of concrete, environmental conditions, surface heating methods, concrete material changes and some other factors.
Concrete is a kind of hot material, shortly after pouring, the temperature of the concrete would rise under the reaction of the cement hydration.
With the advent of cold weather, the tensile stress of the 3 # feature points changes slightly, but it would not exceed the immediate tensile strength. 6 Conclusion a, According to the simulation results, the use of foam insulation board posted outside the template and multi-deck insulation materials with a reasonable construction process, the engineers will be able to reduce the possibility of cracking of the construction in spring and autumn.
