Resistant to salt water . limited resistance to aromatic hydrocarbon including some types of gasoline 耐海水,但对芳香烃物质(包括汽油类)耐度有限。
Based on the conception of the network - changing principle and the two - limited resistance , this paper gives the proof of the transient homogeneous equation for high - order linear circuits and the independent among the two - limited resistance 摘要根据网络变动原理和双限电阻的概念,用数学的方法证明了高阶线性电路的暂态齐次定理的成立。
In contrast , taken as a contact problem , the principal characters of the interfaces can be reflected : ( 1 ) the contact interface is of shear strength which implies that a generic pair of contact points on the interface will displace coincidentally if the tangential force at this point has not reached the limit resistance , else , relative slide between the points will occur along the tangential direction . ( 2 ) no matter the relative slide occurs or not , the contact bodies cannot invade each other in any wise 同时指出,将桩土相互作用按接触问题来处理,可以更好地反映出该接触面的主要力学特征,即: ( 1 )接触面具有相应的“抗剪强度” ,即当接触面上的某一点处的切向应力小于该点处的抗剪强度时,该处桩土共同变形;达到其抗剪强度时,则沿切向发生滑动; ( 2 )在整个变形过程中,桩与土不能互相侵入。
Thus , the author attempt to develop a new model of anchor bolts so as to avoid the disadvantages . in the model , the interaction between the bolt and the geotechnical mass is taken as contact problem , in which if the tangential force at the interface has reached the limit resistance , the relative slide in the interface will occur along the tangential direction . also , the computational parameters in the model have tangible physical meanings and have less difficulty to obtain 为此,本论文提出一种新的锚杆计算模型,它将锚杆与周围岩土体间的相互作用作为接触问题考虑,其计算理论比较严谨,能较好地模拟出锚杆的受力状态及锚杆与岩土体间的剪切?滑移作用,即:锚杆?岩土体之间的接触面具有抵抗强度,当接触面上切向应力小于其抵抗强度时,锚杆与岩土体共同变形;达到抵抗强度时则沿切向发生相对滑动。
Abstract : the system composed of intelligent control modules for three - phase induction motors is introduced in this paper . this module can conduct starting , reverse braking , and reverse conrtol with current limiting resistance . besides , it can also detect low voltage , overload , and open circuit of 1 or 2 phases , and do protection according to the detection . it especially fits to the controlling of motors which often do starting , braking and reversing 文摘:介绍了一种智能三相电机控制模块组成的系统,能在串电阻(电抗)起动、反接制动和换向控制的基础上进行欠压检测、过载检测、断相检测及电机故障保护.尤其适用于起动、制动和换向控制频繁的电机控制场合
