Introduction Rolling is a widely used vital metallic manufacturing process, through which the physical properties of the worked sheets are modified due to the evolution of texture and microstructure in the worked metallic pieces.
Generally, the factors of a rolling system influencing the development of textures and the microstructures in a worked sheet may be classified into two categories, the extrinsic and the intrinsic.
The intrinsic factors arise from the physical nature of the rolled metals, such as structure, SFE, purity and so on.
The extrinsic factors are referred as to the working conditions, like rolling speed, rolling geometry, rolling temperature, etc.
Anyway, once a material to be worked is determined, its intrinsic factors are given, and the working condition, i.e. the extrinsic factors, becomes the decisive part in the formation of rolling textures and microstructures, about which the mechanisms are of great value in industrial practices.

For self-polishing coating with cuprous oxide serving as the main antifouling agent, the release rate of copper ions is one of the most important factors to evaluate its antifouling effect and validity period.
However, some problems arise with such antifouling paints: copper ions prone to aggregate and settle during storage and transportation, leading to the instability of cuprous release rate; copper in the antifouling paints should be used with other auxiliary toxic agents, while the resultant composite toxicity is almost equal to organotin compounds; also a large number of cuprous accumulation in the harbor may reduce the activity of the enzyme inside marine organisms, causing the increase of biological mortality; even copper ions at low concentration may have influence on the health of animals and plants through the enrichment affect of food chain, causing damage to the ecological balance[1].
The well dispersed nanoscale particles reinforced the structure of chlorinated polyether resin based on the different attractive capacities and resultant three-dimensional conjunction, as the resin itself was not dense, thus improved the density and mechanical properties of the coating.

Based on the characteristics of high-piled wharf in coastal ports and staying in particular environment, the mechanical properties of coastal high-piled wharf is analyzed, and the health monitoring parameters are proposed.
And also the dynamic properties of wharf structure can reflect the health state of structure.
Therefore, the dynamic properties of wharf structure should also be used as an indicator of long-term health monitoring.
The monitoring parameters of wharf dynamic properties mainly respect modal information of structure, including structural natural frequencies, mode shapes and damping ratios.
Based on the characteristics of high-piled wharf in coastal ports and staying in particular environment, the mechanical properties of coastal high-piled wharf is analyzed, and the health monitoring parameters are proposed.

Design of remote intelligent meter reading system Yu Tian 1, a 1 Mechanical and Electrical Department, Yantai Engineering & Technology College, Yantai, Shandong, 264006 China aTianyu1965424@163.com Keywords: Remote control; embedded Linux; MCU ARM; 485, M-Bus, modulation and demodulation bus; centralized meter reading system.
Introduction At present, the general area, buildings, schools, industrial and mining enterprises generally realized the water, electricity, gas, heat divided metering mode, table are mostly located in the house, the general need special meter reading personnel into people's homes, this way to the residents of inconvenience and interference greatly, even has the security hidden danger, in terms of management, there are low efficiency, manpower and material resources, human factors, management and many other issues.
Reading through a series of products, can meet the needs of different levels, such as the simple meter reading in households displaying, wired networking reading, wireless networking reading etc., to choose according to the actual situation, can meet the property management, industry management, school students in water and electricity management, industrial and mining enterprises staff management and other kinds of needs. 3.
There are many factors affecting the accuracy of meter reading, there are three main factors, one is the sensor element, meter counting on sensor can accurately transfer metering pulse metering, otherwise the result is not accurate, this is reflected in the metering especially.
Second is the anti jamming performance of products, because the pulse acquisition circuit is long, so inevitably there will be some interference exists, if the meter reading device cannot shield the interference, will inevitably affect the accuracy of meter reading.
