Objective To compare the clinical efficiency of invasive mechanical ventilation with that of noninvasive bilevel positive ventilation in treatment of myasthenic crisis. Methods 24 patients with MC were managed with BiPAP and 16 with Ⅳ.

目的 比较无创性错落式正压通气(noninvasive bilevel positive ventilation， BiPAP)和有创式机械通气(Invasive mechanical ventilation，Ⅳ)治疗重症肌无力危象(myasthenic crisis， MC)的临床疗效。

Effect of sulfurization time, water content, oil as well as sulfur on spontaneous combustion of iron sulfide is investigated on the same sulfide formed from Fe2O3. It indicates that long sulfurization time, some oil, sulfur as well as good ventilation condition could accelerate oxidation and temperatures rise, but uncertain water content and poor ventilation condition lessen the spontaneous combustion tendency.

以Fe2O3的硫化产物为典型样品，研究了硫化时间、水分、油品、硫及通风条件对硫化铁氧化升温特征的影响，结果表明，硫化时间长，适量的油品和硫以及良好的通风条件能够加速硫化铁升温过程，而一定的水分及不良的通风条件则降低了硫化铁的自燃倾向性。
