The products are applied to measure the level of vaporizable liquid especially liquefied gas. Blocking lever is used to divide guide tube into gasification chamber and measure chamber. When liquefied gas is infected by temperature and vaporize into being gas bubbles, the bubbles will rush up along gasification chamber and not enter into measure chamber to affect magnetic float.

该产品适用于易汽化的液体测量，尤其适合液化气介质的液位测量；其特点是用挡杆将液位计主导管内腔分成气化室和测量室，当液位计内液化气受温度影响，内部汽化而产生气泡时，气泡会顺着气化室往上冒，而不会进入测量室影响磁浮子工作，有效地阻止了因气泡

Objective:To evaluate the effect of varicose vein of lower limbs treated by intravenous laser treatment.

目的：研究和评价静脉腔内激光治疗下肢静脉曲张的临床效果。

ABSTRACT:BACKGROUNDTo analyze the curative effects of applying high ligation of great saphenous vein and endovenous laser treatment for the varicosis of great saphenous vein.

［背景］探讨高位结扎联合腔内激光治疗术对大隐静脉曲张的治疗效果。

Methods: 5 cases of craniocerebral diseases with secondary hydrocephalus were selected to be monitored by LNP-Ⅰ translumbar epidural space intracranial pressure monitor and LY-Ⅱ ventricular pressure monitor grabually. With horizontal position, we recorded with IVP and ISEDP pressure one time per 5 minutes , The datums of LNP-I monitor in the repeated operations were compared with that of IVP, While variations of clinic symptoms, wave forms of pressure, and intermittent ventriculus dranage in the intracranial hypertension were observed.

选择5例颅脑疾病继发脑积水患者，采用LNP-Ⅰ型经腰硬脊膜外腔颅内压监护仪和LY-Ⅱ型脑室内压监护仪进行持续监测，病人取水平侧卧体位，以每隔5分钟记录IVP和ISEDP压力数据一次，期间多次重复操作LNP-Ⅰ型监护仪与IVP进行对照，同时观察临床症状，压力波形及颅高压时间断行脑室引流时二者变化。

A number of factors areconsidered including the pressure wave and the viscous resistance in the highpressure oil pipe and the changes of flow areas in the high pressure oil chan-nels.

讨论中考虑了高、低压油管内的压力波动和粘性阻力，以及高压油通道截面变化等因素的影响，同时，对系统中出现的"空腔"现象也作了适当的处理。

Strepsiptera are very specialized insects which carry out a unique type of viviparity with egg formation and embryonic development taking place within haemocoel of the female.
