Based on the failure analysis of hot roll, this paper optimizedly adjusts alloy system and summarizes the experience of rolling wiresand improves ail processing properties. Then, it analyses the effects on some natural parameters such as alloy transfer coefficient, surfacing layers, welding current and arc voltage etc.. It confirms the fitting ageing technique. Also, it discusses the microscopic structural transformation back and forth ageing and the effects on hardness change of overlaying metal by some alloying elements including C, Cr, V, W, Mo, Ni, Mn, B, Re through OM, SEM and X-ray diffraction analyses. Finally the abrasive resistance, red hardness, thermal fatigue property and anti-high temperature oxidability are investigated in experimentation.

In this paper, problems of trend test in clinical experiment are studied mainly by the statistical inference method under order restriction. The ori- gins of order restricted statistical inference are usually dated back to the early 1950s. At about the same time, a number of researchers started working inde- pendently on similar problems. The field developed rapidly during the 1960s and early 1970s and formed the more perfect theory of estimation and test- ing.

Based on this problem this paper designs this intellectualized rack used to dry clothes system. This system uses the signal gathered by DS18B20 temperature sensor, CHR01 humidity sensor and 5547 photoresistance sensor to put into the system processing core monolithic integrated circuit AT89S52. Whether to take back the clothes was determined by the current status of temperature, humidity and sunshine.

Differing from the feed-back error compensation method, the selflearning error pre-compensation method offered by the paper is based on both ANN and time series technique to obtain the error pre-compensating curve using the non-linear ANN pre-compensation model. Because of the self-learning character of the ANN, this new type of precompensation model can be self-adjusted.
