The chemical states and total content of oxygen in high-purity tungsten powder were determined with oxygen determinator RO-316. According to plots of heating temperatures vs. time, it is in-ferred that oxygen exists mainly in the form of WO_3 and adsorbed moisture. In addition, the effect of Sn and Ni as fluxes on the extraction of oxygen in high-purity tungsten has been studied with SEM and metallographical tests.The abtained results are in good agreement with those obtained with Karl Fischer non-aqueous tit...

In addition, the effect of Sn and Ni as fluxes on the extraction of oxygen in high-purity tungsten has been studied with SEM and metallographical tests.The abtained results are in good agreement with those obtained with Karl Fischer non-aqueous tit rat ion, pulse-chromatography and pulse infrared analyses.

用美国RO-316型红外定氧仪对高纯钨粉中氧的测定以及氧的存在状态进行了研究。根据加热温度和时间的对应关系可判断金属中氧的存在状态,得知高纯钨粉中氧主要以三氧化钨和吸附氧的形式存在。另外对锡、镍助熔剂在高纯钨粉中氧提取分析过程中的作用,通过电子扫描电镜和金相组织等手段进行了初步探讨。为验证方法的可靠性,分别用卡尔费体非水滴定法、脉冲加热气相色谱法和脉冲加热红外法进行了分析对照试验,取得了满意的结果。

Hemorrhagic shock was induced in 13 dogs with modified Wigger's method to maintain the mean arterial pressure at 5.33kPa for 60 minutes. 6 dogs were treated with 10% calcium gluconate 0.15ml/kg intravenously at the 60th, 70th, and 80th minute of the oligemic period respectively, while 7 dogs received an equal volume of normal saline at the corresponding time. At the 90th minute of the oligemic period, the shed blood was transfused back to the animals.During the 90-minute oligemic shock period, the mean arterial...

Hemorrhagic shock was induced in 13 dogs with modified Wigger's method to maintain the mean arterial pressure at 5.33kPa for 60 minutes. 6 dogs were treated with 10% calcium gluconate 0.15ml/kg intravenously at the 60th, 70th, and 80th minute of the oligemic period respectively, while 7 dogs received an equal volume of normal saline at the corresponding time. At the 90th minute of the oligemic period, the shed blood was transfused back to the animals.During the 90-minute oligemic shock period, the mean arterial pressure, the peak value of the left ventricle systolic pressure, + dp/dtmax and total peripheral resistance of the treated dogs were significantly higher than those of the controls, but the heart rate, cardiac index, - dt/dtmax and myocardial oxygen consumption showed no significant difference between the 2 groups. After the transfusion of the shed blood back to the animals, no apparent difference of any of the above-mentioned parameters between the 2 groups could be found. In both groups, the oxygen delivery, oxygen consumption, oxygen extract ration and pH value were similar during the oligemic period and after the back-transfusion of the shed blood.The results indicate that exogenous calcium infusion cannot bring about any beneficial effects on the cardiovascular functions, oxygen transport and acid-base balance during hemorrhagic shock.

本文观察了葡萄糖酸钙对狗的出血性休克早期心血管功能、氧运转和酸硷平衡的影响。采用改良的Wigger法复制狗出血性休克[平均动脉压=5.33kpa(40mmHg),持续60min]。于低血容量休克期60、70、80min,一组动物(N=6)静注10%葡萄糖酸钙0.15ml/kg各一次;另组动物(N=7)静注等量生理盐水。失血后90min开始回输储瓶所放血液,30min输完后继续观测功能和代谢指标共60min。组间分析表明:给钙组于低血容量期90min,平均动脉压、左室收缩压峰值、+dp/dt max和总外周阻力均显著高于相应时点的对照组,而心率、-dp/dt max、中心静脉压和心肌耗氧量指数无显著差别。回输所放血液后,组间各项参数均无明显差别。此外,两组动物无论在低血容量期或回输血液之后,其供氧量、耗氧量、氧提取比值和pHa变化均相似,组间无差别。结果提示:出血性休克早期外源给钙治疗,对心血管功能、氧运转和酸硷平衡并无明显而持久地改善作用。

本文观察了急性分段出血狗对酸硷平衡和氧合作用的影响。动物以分段出血方式于60min内使血量丧失达24ml/kg产生中度低血压。停止放血,使低血容量期维持60min,然后回输所放血液并继续观察60min。结果表明:分段出血后心指数、平均动脉压、供氧量和血液pH均显著降低,并伴有静脉-动脉PCO_2差和氧提取的显著增加。提示出血性休克早期静脉高碳酸血症可显著影响机体酸硷状态。高碳酸症可能与低血流状态下CO_2产生增多和排除减少有关。
