The Difference of the Pulmonary-Artery Pressure of the Migrants from Difference Elevation at the 4636 - 4907 m Altitude

Study Objective： To compare and analyze the changes of the pulmonary-artery pressure of the migrants coming from different elevation in the hypoxic environment of 4636 - 4907 m extreme altitude. To explore the susceptibility to hypoxic pulmonary-artery hypertension （PH） in the subjects from different altitude and profession. Methods： By using Color Doppler Ultmsonography （CDU）, measuring the pulmonary-artery pressure of 207 healthy men, who had continuously being lived and worked at the extreme altitude for more than six months, and then were divided into three groups according to their profession and the altitude of original living place. Results： There was a significant difference in the outcomes of pulmonary-artery pressure from the 3 groups. Conclusions： Altitude of original living place, labor intensity are some of factors that impact the pulmonary-artery pressure of the people who exposure to a hypoxic environment. The pulmonary- artery pressure of person without strenuously physical work experience was more sensitive to hypoxic surroundings than that of labor workers. It was not always the fact at an extreme altitude that the moderate altitude mountaineers were superior to other migrants from a lower altitude or plain. The higher PH was found in the groups of the moderate altitude mountaineers and labor workers. It is unlikely certain that one with PH would surfer from HAPE.

硼酸对镍-镁合金电沉积和电化学性质的影响

该文报道了分别用0．05、0．10、0．15、0．33、0．50g／mL的硼酸进行电沉积镍-镁合金的实验。原子吸收光谱实验的结果表明，沉积相中包含不等量的镍和镁，电流效率也随硼酸量的不同而发生不同趋势的变化。从极化实验的结果，讨论了硼酸在电沉积中所起的作用是阻碍氢气的析出。在溶出伏安图中，能观察到5种不同强度的Mg2Ni峰，与XRD得到的结果相吻合。循环伏安测量结果证明镍-镁合金沉积薄膜电极具有良好的充／放电性能。
