Conclusion The automobile exhaust was a main factor resulting in higher levels of saturation of carboxyhemoglobin in exposure group and had a certain impact on traffic policemen's health.
结论汽车废气是使外勤警碳氧血红蛋白饱和度增高的主要因素，已对交通警察产生一定的健康影响。

The saturation effect is also evident as exposure time is longer.
读出信号强度随着曝光时间的增加也明显地呈现出饱和效应。

Using MTS Ultrasonic Measurement System, we studied the influences of water of saturation and pore pressure on velocities of compressional (P) and shear (S) waves in exposure rock specimens.
