In this paper we begin with the electrical principle of the oxygen sensor, analyze the motive detecting method of the oxygen sensor in the LS400 car with the two-dimensional coordinator and explain the way to recognize the fault codes with oscillogram, finally illuminate the meaning of the different fault codes.

在修理发动机电控系统故障时，最想看到的就是发动机故障指示灯有规律地闪烁但有些故障需要在一定条件下，采用一定的方法才能检测到其故障代码，氧传感器的故障代码就属于这种代码通过对氧传感器的电路原理的分析，利用二维坐标图形论述了凌志LS400型轿车氧传感器的动态检测方法，并用波形图说明了该种车型的故障码识别方法，最后指出了不同故障码的意义。

The results show that the perfect strength can be obtained under oxygen partial pressure about 20% O2, overhigh or low oxygen partial pressure is unfavorable for recrystallization of Fe2O3, which causes a decrease of pellet strength. The original hematite will be transformed into magnetite on reduction firstly when carbon-burdened hematite pellet is roasted in oxidizing atmosphere, and then the magnetite will be oxidized to secondary hematite, which is more active than original hematite, therefore, the induration strength of pellet is able to be enhanced.

研究结果表明：内配碳赤铁矿氧化球团在接近空气配比(氧含量约20%，体积分数)的氧化性气氛中焙烧强度最大，氧含量过高或过低都会影响Fe2O3的再结晶，使球团强度降低；在氧化性气氛中焙烧含碳赤铁矿球团时，原生赤铁矿先还原为磁铁矿，磁铁矿再氧化成活性较高的次生赤铁矿，提高了赤铁矿焙烧固结性能和球团强度。

OBJECTIVE: To investigate the influence of hyperventilation on oxygen saturation in the internal jugular vein, difference in oxygen and lactic acid contents between the cerebral arteries and veins in patients with serious traumatic brain injury.
