查询词典 barium

During melting and throughout the crystal growing process the barium acts as a devitrification promoter and creates a layer of devitrified silica on the inside crucible surface in contact with the melt resulting in a lower level of contaminants in the melt and grown crystal.

在熔化以及晶体生长的整个过程中，钡起失透促进剂的作用并且在与熔体接触的坩埚内表面上产生失透二氧化硅层，从而降低了在熔体以及生长的晶体中的污染物量。

BARIUM CHLORIDE: Melting Point 962'C, It absorbsmoisture in air to form double hydrated salt.

Barium strontium titanate shows high dielectric constant and low dissipation factor and holds great promise for wide applications in dynamic random access memory, transducer and infrared detector.

钛酸锶钡薄膜具有较高的介电常数和较低的介质损耗，在动态随机存储器、传感器、探测器等方面应用前景广阔。

Barium calcium titanate crystal is a new photorefractive crystal. The BCT crystal has more excellent electrooptics properties than BaTiO_3 and has no phase transition at 5℃, which make this material quite attractive for applications.

钛酸钡钙晶体是一种新型的光折变材料，由于其优于钛酸钡的电光性能及无室温相变的优势，使其具有更大的应用前景。

The patient underwent exploratory laparotomy after failure of medical treatment. A bezoar 8×3×3cm in size, was lodged and extracted via enterotomy over the compatible obstruction site of barium meal examination.

患者因内科治疗失败而接受剖腹探查，结果发现一个8×3×3公分大的粪石位於与小肠钡剂检查相吻合的阻塞部位，并经由肠切开术将之取出。

The anti-jamming ability of igniter depends on the charge in the igniter. The combustion of the igniter charged with barium nitrate and those charged with magnesium powder and PTFE is stable, while the igniter charged with zirconium hydride and lead oxide is unstable. The standard error of duration of the third kind of igniter flame is 523 ms ,and also its nozzle hole is blocked seriously.

不同药剂的点火具抗干扰性能不同，其中以硝酸钡为药剂主成分的点火具和以镁粉＋PTFE为药剂主成分的点火具燃烧性能稳定，以氢化锆、二氧化铅为药剂主成分的点火具工作稳定性较差，火焰持续时间标准差为523 ms，点火具喷孔堵塞严重。

Arious techniques used to make this determination can include barium esophagraphy, esophagoscopy, and CT.

各种常用诊断技术包括食管钡餐、食管镜检查和CT。

Of 14 misdiagnosed children, the misdiagnostic causes were acute gastroenteritis (7), pneumonia (3), congenital diaphragmatic eventration (1), congenital pulmonary cyst (1), acute pyopneumothorax (1), and pneumothorax (1), and the definite diagnosis was made by chest xray, barium or iodinated oil examination, CT or ultrasonography.

结果 本组16中14例转入我科前误诊误治，其中误诊为急性胃肠炎7例，小儿肺炎3例，先天性膈膨出、先天性肺囊肿、急性脓气胸和气胸各1例，误诊率高达87.5%。14例经X线检查、钡剂或碘油造影、CT、超声检查确诊；15例治愈，1例死亡。

The result indicated that HSC could obviously cut down the occurrence of rentricular vibration induced by chloroform in mice,lengthen the time of arrhythmia appearance,shorten the time of arrhythmia continuum and conversion induced by barium chloride in model rats,it also could shorten the time of ventriclar extrasystole and ventricular tachycardia in model rats induced by aconitine.

结果表明：黄松胶囊能明显降低氯仿所诱发小鼠室颤的发生，明显延长氯化钡模型大鼠心律失常出现时间，缩短模型大鼠心律失常持续和复律时间，尚能明显缩短乌头碱性大鼠心律失常的室性早搏及室性心动过速持续时间，与模型对照组比较均有统计学差异。
