This paper reports the study of in-situ deposition temperature (ranging from 20°C to 80°C) effects on Parylene-C properties in terms of glass transition temperature (Tg), β-relaxation temperature (Tβ), Young's modulus and crystallinity (including crystallite size). The results show that the Parylene-C (PA-C) thin film deposited at higher deposition temperature exhibits higher Tg and Tβ, revealing...
The humiture monitor system for small grain depot based on AT89C52 can measure the humiture by temperature and humidity sensor. Through compare the detection value and setting value, the system can control the LED to light, then the staffs operate the temperature and humidity reduction equipments to control the temperature and humidity to the setting value. The system design include hardware and software,...
During the preliminary three to five days of casting completion of compressor unit in large volume concrete, the temperature difference between inside and outside of concrete excesses its ultimate because of the sudden temperature increase from the hydration heat of cement and the heat-insulating property of concrete together with the striking of the cold wave. In addition, the evaporation of the...
According to the effect of water with suspended particles to light propagation and temperature to turbidity and pressure, a multi-parameter measuring system with wireless transceiver and automatic temperature compensation is designed. The measured value of turbidity, temperature and pressure are transmitted to host computer (its monitor system software is written under VisualBasic6.0 program) by radio...
