Results: the ophthalmic bloodstream speed increased obviously, the ophthalmic blood vessels of hypertension was in a state of low bloodstream and high resistance.
结果：高血压患者眼血管血流速度明显减慢，阻力指数明显增高，呈低流速高阻力状况。
In the second phase group it was in a state of normal systolic flow velocity, low diastolic flow velocity and high renal vascular resistance.
第二组处于收缩期正常流速，舒张末期低流速，肾血管高阻状态。
The microcontroller's pin connects to ground using pulldown resistor R1 with resistance, typically, of a few hundred kilohms to impress the high-impedance state on the pin.
