研究了不溶性腐殖酸吸附水中对硝基苯胺的吸附热力学特征，探讨了pH、温度、腐殖酸的用量对对硝基苯胺吸附行为的影响．结果表明：时硝基苯胺在不溶性腐殖酸上的等温吸附曲线为非线
On the Validity of Janak’s Theorem and Ground State Energies of Ensembles of Interacting Quantum &am
It is established that for finite number of electrons, N ∞, and in the limit T = 0, the line of reasoning leading to the proof of Janak’s theorem is flawed, b
多轴运动控制一直是很多机床生产厂家所需求的重要方向,也是衡量数控系统优劣的一项重要技术指标.但是,目前大多数数控系统生产厂家多提供4～5轴控制系统,而能提供6轴以上控制
Heating of the Electrons and the Rectified Current at the Contacts That Are in an Alternating Electr
The paper deals with the heating of electrons and current rectification in contact, which is located in an alternating electromagnetic field. It was found that
数控加工过程中，CAM系统生成的刀具轨迹会直接影响加工的质量、时间等多个方面。刀具轨迹中的连接部分在整个轨迹中占有一定的比重。其性能表现对最后的加工结果具有很大的影
