1 . hemodynamic effects of agmatine in dahl salt - sensitive hypertensive and dahl salt - resistant rats the hemodynamic effects of agmatine were investigated in anaesthetized dahl salt - sensitive ( ds ) hypertensive and dahl salt - resistant ( dr ) rats . the results are as follows : ( 1 ) agmatine ( 1 , 10 , 20 mg / kg , iv . ) 一、胍丁胺对dahl盐敏感型高血压大鼠和dahl盐抵抗型大鼠血流动力学的影响在麻醉dahl盐敏感型( ds )高血压大鼠和dahl盐抵抗型( dr )正常血压大鼠，研究了静注胍丁胺对血流动力学的影响。
Through the mr dampers of homemade , we have a series of test of damper , including the relationships between force and displacement , force and amplifier , force and frequency etc . and simulating the revised model - bingham and model - dahl to prove the correctness and rationality of two models 通过自制了mr阻尼器的模型，并对阻尼器的性能进行了一系列的测试，包括力?位移实验、振幅、频率测试和蓄能器测试。并对修正的bingham模型和修正的dahl模型进行了仿真，证明了两种模型的正确性和合理性。
