negative differential meaning in English
负差率
Examples
- Test standard for evaluating the simulated wind uplift resistance of roof assemblies using static positive and or negative differential pressures
用静态正和或负差压评价屋顶组件耐模拟风吹起的试验标准 - In the experiment we also observed negative differential resistance characteristics of gesi hbts with heavily doped base at high collector - emitter voltage and high current . a new interpretation to this phenomenon was given . this
在实验中我们还观察到，在高vce和大电流下，重掺杂基区gesihbt出现负阻现象，我们对这一现象进行了新的解释，认为这是由热电负反馈导致的。 - For the requirement of more negative differential resistance ( ndr ) routes , three split quantized energies are formed in the four - period inp / ingaas superlattice structure with relatively thin ingaas quantum wells under ideal flat - band condition , and high - field domain in the superlattice is formed under sufficiently large operation bias
为获得?多轨迹的负微分电阻，本研究组件使用?相当薄之砷化铟镓?子井，可使四周期磷化铟/砷化铟镓超晶格结构在平带情况下形成三个分?的?子化能阶，且于足够大的操作偏压下在该超晶格结构中形成?高场区域。 - However , when the applied bias voltage is located within negative slope regions of u - i curve , the superlattice will undergo a very fast dynamic process , changing from one stable state to another stable state . the superlattice exhibits temporal current oscillations in the negative differential conductivity region at fixed d . c
当外加电压使电流处于正微分电导区变动时，超晶格的高低电场畴之间的畴边界不发生移动，只是相应的电场强度作些调整；当外加电压使电流处于负阻区域时，超晶格将经历一个稳态到另外一个稳态的动力学转变。
