primary shock

Problems: The primary stress to which the surface of the mould is exposed are thermal shock, abrasion and chemical reactions between the liquid alloy and the iron in the steel mould.

问题：压铸模具表面主要面临的问题有热冲击、磨损、液态合金与模具钢的化学反应等。

Conclusions: The results indicate that the prognosis of traumatic patients with ARDS depends on injury severity, infection, shock, primary lung injury and inhalation injury.

结论：创伤严重程度、感染、休克、原发性肺损伤和误吸是并发ARDS的主要危险因素。
