查询词典 conduction current

Moreover, the constant electrical conductivity of the asphalt concrete increased slowly with the temperature increasing, which presented a normal temperature effect. The mechanism of the electric conduction of the asphalt concrete can be explained by using electric channels and tunnel effect in which a net factor, n, which indicates the capability of conductive net formation in the concrete. Combined with the transfusion theory, a type of sea-island model is proposed.

Both the simulation and experiment were carried on and the results showed: the generally used three-phased conduction of brushless DC motor should be regarded as a special case for DSC, corresponding to the highest speed running of DSC. The simple structure of DSC for BLDC produced excellent torque dynamic response within 1ms.

仿真与实验证明：常见的无刷直流电机三三导通方式可以看作是直接自控制的特例，对应直接自控制在全速运行；转矩动态响应时间不超过1ms。

2 Clinical signs: tendon reflex, knee jerk diminish or disappear; Theinspection had limbs nerve conduction velocity was delayed, Theincubation period is extended, and lower voltage electrophysiologicalabnormalities.

We report a GBS patient who after receiving an operation for polycystic liver disease under general anesthesia developed weakness of upper and lower extremities on the 3rd postoperative day, with decreased deep tendon reflex, which ultimately evolved into respiratory failure. Slurred speech and bilateral ptosis were also noted. All these manifested an acute peripheral polyneuropathy combined with bulbar involvement. According to the clinical picture, CSF examination and results of nerve conduction tests, Guillain-Barré syndrome was diagnosed.
