越来越多的人认识到把自动控制理论应用到生物医学领域,将会得出非常有价值的成果。本书的中心内容就是其中一例。 哺乳动物血浆中血糖浓度的正常值约为100mg/100cc。血浆中胰岛素浓度约为25μu/cc。如果血糖浓度偏离正常值,则血浆中的β细胞将刺激胰脏增大或减少胰岛素之分泌量以改变血浆胰岛素之浓度,促使机体组织改变吸收血糖之能力,令血糖浓度恢复正常值。糖尿病患者的症状是血糖浓度高于正常值。早期病人的病因可能是β细胞对
More and more people realize that the application of automatic control theory to the field of biomedicine will produce very valuable results. The center of this book is one example. The normal blood glucose concentration in mammalian plasma is about 100 mg / 100 cc. Plasma insulin concentration is about 25 uu / cc. If the blood glucose concentration deviates from the normal value, then the beta cells in the plasma will stimulate the pancreas to increase or decrease the secretion of insulin to change the concentration of plasma insulin, causing the body tissue to change the ability to absorb blood sugar, so that the blood sugar concentration returns to normal. The symptoms of diabetic patients are blood glucose levels higher than normal. The etiology of early patients may be β-cell pairs
