THEORETICAL AND EXPERIMENTAL RESEARCHES ON JOINT-TORQUE OF THE UPPER LIMBS SYNERGISTICALLY MANIPULAT
Turning a steering wheel is a typical example of human movements that are constrained by the physical environment.The constraints decrease the mobility of the human arm and lead to redundancy in the d
Taiwan is populous and located in seismic belt around Pacific Ocean, otherwise, landforms is narrow and smaIl.There are no redundant areas to be selected as factory, for Hi-Tech industry to avoid focu
VIBRATION AND POWER FLOW ANALYSIS OF PERIODICALLY REINFORCED PLATES WITH ARBITRARY BOUNDARY CONDITIO
In this paper an analytical method is proposed to investigate the vibration and power flows of periodically stiffened plate with general boundary conditions.Both the plate and stiffening beams are mod
Damping treatments have been extensively used as a powerful means to damp out structural resonant vibrations[1-3].Usually, damping materials are fully or partially covered on the surface of structure[

油酸甲酯是一种重要的化工原料,目前工业上采用油酸与甲醇在硫酸作用下酯化合成[1].由于硫酸与产品同为液相,彻底分离困难,并且硫酸腐蚀仪器,对环境也有较大污染,因此目前科学研究在进行研制替代硫酸的新型催化剂.1998年赵东元等人合成出一种新型材料-介孔材料SBA-15,该材料具有高度有序的大孔径(6-30hm)、孔体积大(1.0cm3/g)、较厚的孔壁(4-6nm)以及良好的催化吸附性能[2].
