单极性

One challenge is the changing definition of bipolarity."What we have seen over the past few years is the expansion of the bipolar spectrum," said Dr. Sharma. It may be helpful to look at unipolar depression and bipolar disorder as opposite ends of a continuum, rather than distinct diseases, he added.

面临的挑战是双极性定义的改变，Sharma博士指出，我们回顾这几年来，双极性异常所涵盖的范围越来越广；他附带表示，将单极性忧郁与双极性异常视为光谱的两端，而不是完全不同的疾病，可能是有帮助的。

Using the most universal two ways is: one is restricted the unipolarity drive type and another is restricted the frequency multiplication unipolarity drive way.

应用最普遍的两种方式是：受限单极性驱动方式和受限倍频单极性驱动方式。

The unipolar cognitive thinking has a variety of performances such as the cognitive one-sidedness of the subject and the object of moral practice; the unipolarity of morality problem-solving objects; the unipolarity, caused by the sheltered negative impact of multi-cultural values, of moral problem-solving countermeasures; the cognitive unipolarity of the relation between administrators and teachers.

这种认知思维的单极性有种种表现，主要表现为：师德实践主、客体认知的片面性，师德问题解决对象的单极化；多元文化价值消极影响的消除被遮蔽，进而导致师德问题解决对策的单极化；管理者与被管理者之间关系的认知单极化。

To eliminate common-mode voltage of cascaded multi-level inverter, three kinds of phase-difference SVM based on left and right bridge vectors are proposed firstly. From these three modulations, equivalent SPWM components are deduced, and the unipolarity and bipolarity of output waveforms are analyzed. 2π/3 PD-SVM (phase-difference space vector modulation) is testified be unipolar.

为消除级联型多电平逆变器的输出共模电压，首先提出了基于左、右桥臂矢量的三类相差空间矢量调制(space vector modulation，SVM)技术，数学推导出三类调制技术的等效正弦脉宽调制(sine pulse width modulation，SPWM)的调制波，并分析了其各自相电压输出波形的单、双极性，证明2π/3相差SVM必为单极性调制。

Compared with convertional silver zinc reserve battery monopolar,bipolar battery has many advantages.

与传统的单极性锌银贮备电池组相比，双极性锌银贮备电池具有许多优点。

The circuit, which can transform the signal from bipolar to monopolar and linearly restrict its amplitude for matching the ADC of S3C2410, according to the superposition principle of circuit theory , is specifically designed and fully given by myself . Its design idea is also deeply analyzed.

为与本系统选用的S3C2410内置的ADC可靠配接，根据电路理论中的叠加原理，特别自行设计给出了双极性转单极性并线性限幅的完整电路，并深入分析了其设计思想。

Dr. Sharma and colleagues used the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition to reinterview 61 patients diagnosed with unipolar depression who had failed to respond to at least two adequate courses of antidepressants. By examining their symptoms over time as well as their family history, the researchers discovered that 35% of these patients had a form of bipolar disorder. Even more remarkably, after following them for a year, fully 80% of patients were deemed to have bipolar disorder.

Sharma博士与其同事使用精神异常诊断与统计手册第四版的结构式临床面谈，针对61位被诊断为单极性异常，而且至少对两种以上抗忧郁药物，在使用足够疗程下，没有反应的病患进行再次面谈；透过检查他们随著时间表现出来的症状以及家族史，研究者发现，这些病患中的35%具有双极性异常的形式；更值得注意的，在追踪一年后，将近80%的病患被视为患有双极性异常。
