负反馈

It is useful to make assessment of a decision regardless of the feedback is positive or negative.

决策评估是有用的，无论其反馈意见是正面的还是负面的。

On the basis of this, the role of condensational latent heat release is studied emphatically and a conceptual model of mutual positive feedback mechanism between the growing of meso-α-scale cyclone on MeiYu front and its accompanying intensifying precipitation due to stable condensational heating is posed, i. e. condensational heating generates negative allobar, divergent wind kinetic energy promotes meso-α-scale cyclone growing, and simultaneously, updraft motion is also reinforced, precipitation continues intensifying.

并在此基础上着重对凝结潜热释放的作用进行了研究，提出了一种由稳定性凝结加热作用而导致的梅雨锋上α中尺度气旋发展与降水增强之间相互正反馈机制的概念模型即凝结加热可以产生负变压，变压风动能通过转变为旋转风动能促进中气旋发展，同时上升运动得到增强，降水增幅。

The dynamic characteristics of negative stiffness Duffing system with delayed feedback control are investigated.

对时滞反馈控制负刚度Duffing系统的动力学特性进行了研究。

METHODS: The maximum number of platelet binding sites and their affinity for [3H]-rauwolscine, a selectie alpha 2-AR antagonist, were measured in unmedicated and medicated major depressed patients and in normal olunteers.

背景：曾认为抑郁症可以伴随中枢α2肾上腺素受体密度的降低，继发突触前儿茶酚胺神经元负性反馈的损害，导致刺激后去甲肾上腺素输出和释放去抑制功能的减弱。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".
