Objective To probe into the effect in severe craniocerebral injury patients with hyperventilation treated by early stage mechanical ventilation.

目的 探讨早期机械通气对重型颅脑损伤自发性过度通气患者的治疗作用。

The design of the seam tracking sensor is the key work in the realization of the welding automatization. A novel touch photoelectric sensor for seam tracking was designed on the base of getting over the shortcoming of non-touch seam tracking sensor and using the principle of the photovoltaic translation. The idler pulley can touch the seam closely, then the sensor can realize the auto-tracking by the oriented function of the groove. If the offset of the idler pulley location appear, the sensor can change the offset to the voltage using the cell of the photovoltaic translation and the cell of signal processing.

焊缝跟踪传感器的设计是焊接自动化实现过程的重要环节，在此克服非接触式焊接跟踪传感器易受干扰的缺点，利用光电转化的原理，设计了一种新颖的接触式光电焊缝跟踪传感器，该传感器利用特制导轮与坡口紧密接触，依靠坡口的机械导向作用实现焊缝自动跟踪，当导轮位置发生偏移，利用光电转换单元以及信号处理单元，可将偏移位移转化为模拟电压量。

3The degradation of chitonsan by both high pressure homogenization and the combination of high pressure homogenization and H_2O_2, didn\'t destroy basic functional groups and structure unit of chitosan, indicating that most of fragmentation happened onβ-(1,4) indican bond.

4高压均质-H_2O_2联合降解壳聚糖的效果优于高压均质降解或H_2O_2氧化降解，高压均质技术在保持自身对壳聚糖机械剪切断链作用的同时，还促进了H_2O_2对壳聚糖的氧化降解。
