unconditioned

Bernstein and her colleagues also proposed a model that associative learning takes place when a conditioned stimulus is followed by an unconditioned stimulus, triggering convergent neurons.

伯恩斯坦博士和她的同事还提出一种模型，即当给予非条件刺激物后给予条件刺激，联想性学习就会发生，即触发了会聚神经元。

Quantum key distribution protocol makes use of single photon of quanta-randomicity to achieve unconditioned security key distribution, especially which is the realism significance of research way in quantum information at present.

量子密钥分配（QKD）协议利用单光子固有的量子随机性实现具有无条件安全性的密钥分配，是目前量子信息领域中特别具有现实意义的研究方向。

But the lenience should not be limitless and unconditioned and teachers should have reasonable right to punish improper behaviors to ensure their role in educational activities.

但教师宽容是有限度、有条件的，对于超出教师宽容限度的教育对象的不当行为，教师拥有合理性惩罚权，确保教育活动得以顺利进行。
