After the subsequent hot compression at condition at 1273 K and
strain rate less than 1 s-1, and 1223 K and strain rate less than 10 s-1, ultra fine grains less than 1 µm
with residual M2N were obtained.
Particularly, the deformed condition at 1273 K and strain rate less than 1 s-1, and 1223 K and strain rate less than 10 s-1 can exhibit ultra fine grains (less than 1 µm).
The ultra-fine grains (less than 1 µm) were obtained under deformed condition at 1273 K and strain rate less than 1 s-1, and 1223 K and strain rate less than 10 s-1.

Computational results
Numerical integration applying the explicit 4/5th order Runge-Kutta formula by Matlab and the implicit direct integration algorithm by Abaqus were used to solve the lumped parameter dynamic model of the geared rotor system and the FEM dynamic model of the housing sub-system, respectively.
The acceleration responses in time and frequency domain of sensor 1 and sensor 2 as shown in Fig.1 (b) are shown in Fig.4 and 5, respectively.
Also, it can be seen that the vibration peaks of sensor 1 and sensor 2 appear at about 976 Hz and 1953 Hz.

Earthworm survived at 0~16 mg kg-1.
However, on day 4 an obvious increase in the activity of CAT was recorded at 4 mg kg-1 and 8 mg kg-1 PCBs compared to the control.
In comparison with the control, no significant changes in SOD activity were observed on day 4, 8, 16 after exposure to 1-16 mg kg-1 PCBs.
