Good elasticity , super light in weight , which is conformable for juniors daily practicing and holding up before net ; low vibration and shockness , the potential harm to juniors will be greatly reduced 球拍弹性非常好、重量超轻，适用于小球友们日常拉球训练和网前拦截；球拍震动小、晃动低、挥拍自如，对小朋友可能产生的伤害性很低，且该系列球拍使用是对球技的要求非常低。
These results , combined with earlier work , suggest that a distress response to a noxious stimuli may be almost entirely subcortical , however , the finer discrimination and emotional overlay of this painful appreciation may be cortical in location ( 1 ) 这些结果与早期研究综合表明，对伤害性刺激的不良应激反应可能完全是皮层下的，然而，对疼痛鉴别的良好判断和情感性加重在局部可能为皮层水平。
Stubbing a toe or leaning against a hot stove activates neurons ( nerve cells ) called nociceptors that respond specifically to hurtful stimuli , such as extreme temperature or mechanical pressure , or to chemicals generated in response to injury or inflammation 当脚趾踢到硬物或身子靠上发烫的炉子，都会活化称为痛觉受器的神经元（神经细胞） ；这些神经元专对伤害性刺激产生反应，好比说极端的温度或机械压力，或者是组织受伤或发炎时产生的化学物质。
The selective action of capsaicin on primary afferent fibers that transmit nociceptive information simulates nociceptive stimulation in vivo , therefore , the ne depression of primary afferent terminal neurotransmitter release might be significant on nociceptive modulation at spinal level Caps选择性地作用于传递伤害性信息的初级传入纤维，模拟了在体伤害性刺激，因此， ne对初级传人终末递质释放的抑制，在脊髓水平的伤害性信息调控过程中可能具有重要意义。
Substantia gelatinosa ( sg ; lamina ii ) of the spinal dorsal horn is the first station of the peripheral nociceptive information , which receives the termination of both non - and thin - myelinated primary afferent fibers and brainstem descending fibers , and plays an important role in peripheral nociceptive information transmission and modulation 脊髓背角层(胶状质) ，是接受外周伤害性信息传入的初级门户，既接受无髓和薄髓初级传入纤维的投射，也是脑干向脊髓下行投射纤维的终止部位之一，在外周伤害性信息传递和整合中发挥重要作用。
