ET tube insertion procedures were performed on 59 pediatric patients aged newborn to 17 years (33 boys) due to cardiopulmonary arrest or impending respiratory failure. Ultrasound images were taken before and after the procedure in two-dimensional and time-sector modes using a portable ultrasonic machine. The subxiphoid window at the mid-upper abdominal — just beneath the xiphoid process and the lower margin of the liver — was used most often, with a wide transducer sector angle (90 degrees) for bilateral scanning of the diaphragm.

这项试验对59位从新生儿到17岁（33位男童）的小儿科病患进行插管，插管的原因是因为心肺衰竭或是严重的呼吸衰竭；在插管前与后使用可携带式超音波机器进行二度空间与时间象限的超音波显影；最常使用中上腹的剑突影像，就在剑突与肝脏下下缘部份的影像，与以宽的转换区间角度（90度）作横隔膜双侧扫描。

The Langmuir Blodgett technique was employed to modify the PVC liquid membrane, the LB film of trioctylcetyl ammonium chloroauric acid was deposited on the surface of PVC liquid membrane, and the gold selective electrode with such modification has been fabricated.

1引百 LB膜技术〔''是近年来超分子组装化学中应用最多和相对最成功的分子装配技术，因能较好地在许多固体表面按设计方式组装空间有序的超分子体系，特别是其器件研制最基本的实验手段之一卿，由于LB膜修饰层有序，高密，超薄，能从根本上改进电极体系及其反应过程的性质和行为
