According to the large numbers survey of the cracks actuality in Chongqing, this paper investigated the basic performance of light aggregate concrete blocks, autoclaved aerated concrete blocks and mortars which influence the cracks in the laboratory and monitored the deformation of the frame structure infilled wall with the autoclaved aerated concrete blocks and shale particle concrete hollow blocks in the construction local.
This article briefly describes some new approaches to stimuli-sensitive polymeric micelles and hollow spheres, which were developed in the authors' laboratory in recent years.
A standard procedure, for modelling a laboratory-scale wire-to-cylinder electrostatic precipitator and for guiding the research of the set point, is presented.
The influencing factors of extracellular polysaccharide (EPS) produced from a strain of lactic acid bacteria (LAB L15) were studied by using the phenol-H2SO4 method.
In this paper, chlorophytes collected from 253 biological soil crust samples in Gurbantunggut Desert in Xinjiang Autonomous Region, China were studied by field investigation and microscopical observation in lab.
the Machine Intelligence and Translation Laboratory (MI>amp;amp;T Lab), the Intelligent Technology and Natural Language Processing Laboratory (ITNLP) and the Information Retrieval Laboratory (IR-Lab).
The evolution of activated sludge settleability and its relationship to membrane fouling in a submerged membrane bioreactor were studied at a lab-scale equipment fed with synthetic wastewater.
Engineers and scientists concerned with control problems formed new professional groupings; university courses in the subject began to be offered; and research groups were set up in industrial, academic, and government laboratories.
The text does not attempt to give a complete and meticulous account of the many relevant and excellent reports published by many other laboratories, so it is not a review of the field in a conventional sense.
Depending on the vibration frequency, the body rotation velocity in the laboratory reference system may be higher or lower than the cavity rotation velocity and in the resonance region they may differ by several times.
