In this microscopic view of a recent myocardial infarction, there is extensive hemorrhage along with myocardial fiber necrosis with contraction bands and loss of nuclei. 心肌梗死不久可见广泛出血合并心肌纤维坏死以及细胞核消失。
The research results show that although the swelling and contraction process of swelling clay are of much similar characteristics, both processes can not be inversed, and the water absorption swelling speed is quicker than the water loss contraction speed. 研究结果表明,尽管膨胀粘土的膨胀、收缩过程有很多相似特征,但两者并非是完全可逆的过程,其吸水膨胀速度远比失水收缩速度快。
Functional electrical stimulation ( FES) refers to the muscle contraction by electrical stimulation, which can compensate for the loss of body function for nerve injury. 功能性电刺激(FunctionalElectricalStimulation,FES)是近来逐渐兴起的一种电刺激治疗技术,通过电流刺激肌肉收缩,从而代偿因神经损伤失去的机体功能。
