We select ni / cr alloy resistor as element together with ceramic embedding hearth ; select small flat - and - disc heat - even hubby ceramic sample holder , select ni / cr & ni / si thermoelectric couple ( type k ) as thermoscope with threads 0 . 5 mm in diameter which is installed in the middle of the holders symmetrically ; select aluminum silicate fire - retardant fiber as materials for heat preservation ; design some hardware , for example temperature controller & transporter , signal amplifier etc ; design controlling curve to heat stove ; and introduce the method of least squares nonlinear regression and subsection function to deal with data . in order to obtain the reasonable operation conditions and operation curve , we have also done many theory analysis and experiment discussions 通过理论和试验探讨，选用镍铬合金电阻丝作为加热元件，配以陶瓷质埋入式炉膛；选用陶瓷质小尺寸扁平?圆盘均热块体型样品支持器；选用0 . 5mm丝径镍铬?镍硅热电偶( k )作为测温元件；热电偶对称安置在样品支持器容器的中部；选用硅酸铝耐火纤维作保温材料；合理选用和设计了温度控制器、温度变送器、信号放大电路等硬件；采用升温曲线来控制炉膛供热过程；采用最小二乘法非线性回归与分段函数相结合的曲线模拟方法，进行图形处理。
This paper investigated the electrorheological ( er ) characteristics of two suspensions of starch particles ( a ) and aluminosilicate particles ( b ) in silicone oil respectively , and also their transmitting properties on a simulated device of cylindrical er clutch ( erc ) by comparison , only to show that a is a kind of electrorheological fluid ( erf ) with definite plastic yield - point and can be subjected to a narrow voltage range on erc , while b is a kind of pseudo - plastic erf and can be subjected to a wilder voltage range on erc 本文研究了硅油-淀粉( a ) 、硅油-硅酸铝( b )两种er流体的电流变性能，并通过一套筒式er离合器模拟传动装置，研究且对比了这两种er流体在筒式er离合器上的传输特性。结果表明a是具有塑性屈服点的流体，其在er离合器上有效调速电场范围较小； b是假塑性流体，其在er离合器上有效调速电场范围较宽。
