在阀门维修中进口减压阀维修比较复杂；进口减压阀是采用控制阀体内的启闭件的开度来调节介质的流量，将介质的压力降低，同时借助阀后压力的作用调节启闭件的开度，使阀后压力保持在一定范围内，在进口压力不断变化的情况下，保持出口压力在设定的范围内，保护其后面管道、设备的压力、温度的稳定

The invention discloses a 3, 5-2-0-(4-chlorobenzene chlorobenzene)-2-deoxidising- D-red-furanoside that contains alpha body and beta body. The method includes the following steps: dissolving chlorine indicant into tetrahydrofuran, quickly adding to alcoholic solutioin, whisking and reacting, after reacting, vacuuming and steaming solvent to gain mixture of alpha body and beta body, taking separation by column chromatography to gain separated alpha body and beta body.

本发明公开了一种3、5-二-O-(4-氯苯甲酰基)-2-脱氧-D-赤-呋喃糖苷，它具有式表示的α体和式表示的β体，制备方法采用在室温下，将氯糖苷溶于四氢呋喃中，然后快速加入到醇溶液中，搅拌下进行反应；反应结束，减压蒸掉溶剂，得到白色固体，将该固体用石油醚溶解，过滤除去不溶物，再次减压蒸去溶剂，得到白色α体和β体的混合物，用柱色谱法进行分离，得到单独的α体和β体。

Methods. This prospective study included 152 consecutive patients, sequentially divided into 2 groups, underwent Windows technique and decompressive laminectomy group by 2 groups of surgeons.

Twenty-five femoral heads showed osteosclerosis and trabe...

治疗结果：Ⅰ期行钻孔髓内减压术，Ⅱ、Ⅲ期行钻孔减压植骨术。

objective to evaluate early signs of avascular necrosis of femoral head in adult by ct and to guide clinical treatment.methods the cases with suspicious diagnose of anfh were scaned in the both hip joints by x ray and ct to find the early signs of anfh with ct.results early signs of anfh using ct showed that, in 38 femoral heads 31 cases, there were radiate star shape of high density osteosclerosis of the trabeculae in 13 femoral head.twenty five femoral heads showed osteosclerosis and trabeculae structure disappearing and vague,incoordinately low ostedensity area and cyst change.there were fracture under the cartilage and light subsid in 5 cases.the cases in stage ⅰwere given decompression, while the pationtsresul in stageⅱand stageⅲ were given decompression and ostetransplant.conclusion ct results show that the sign of the high osteodensity and low osteodensity and cyst change can disply early anfh.

摘 要］目的：探讨成人股骨头缺血性坏死的早期ct征象并指导临床治疗。方法：对临床疑诊anfh的全部病例均行x线平片及ct检查，分析anfh的早期ct征象。结果：早期anfh的ct表现：31例38个股骨头，其中13个股骨头骨小梁呈放射状高密度的"星状征"，骨小梁境界清楚、锐利，属ⅰ期；25个股骨头表现为骨硬化，骨小梁结构消失、模糊不清，骨密度减低及囊性改变，属ⅱ期；并有5个股骨头在ⅱ期影像学改变基础上出现软骨下骨折及轻微塌陷，属ⅲ期。治疗结果：ⅰ期行钻孔髓内减压术，ⅱ、ⅲ期行钻孔减压植骨术。

Into two operating speeds can be individually adjusted by a work into another work entered into, due to pressure reducing valve has been in a vacuum state, the fuel tank does not appear pediment phenomenon.

两种工进速度可以单独调节，由一种工进转入另一种工进时，由于减压阀一直处于减压状态，油缸不会出现前冲现象。

Oxygen pressure reducing valve installation precautions:(1) according to different application requirements, there are many specifications of the oxygen valve.
