一、绪言直至最近,氮基热处理气氛系统采用的是高纯氮气,它是在深冷过程中通过空气分馏来制取的。现在,利用变压吸附(p.A)技术的发生器可以在现场制取一种纯度比较低的替代型氮气源。这种氮气由于含少量的残余氧,因此并不能在所有热处理场合使用。然而,由于经济和技术上的原因,这种气源已成功地应用于许多工艺中。本文将详细叙述这些应用的结果,并提出同样可以成功地应用这项技术的其它场合。

In today’s automotive industry almost all car and truck radiators, oil coolers and air conditioning heat exchangers are manuf.ctured using Nocolok Controlled Atmosp.ere Brazing (CAB). One of.the most critical elements of.the brazing p.ocess is the atmosp.ere used to p.otect the f.ux. Oxygen content is the major variable af.ecting the p.rf.rmance of.the nitrogen atmosp.ere. f.rnace design and f.ow rate are the major f.ctors af.ecting oxygen content. Op.imisation of.these atmosp.ere p.rameters has a signif.cant imp.ct on op.rating cost, and on the quality and consistency of.the brazed p.oduct. Comp.tational f.uid dynamics p.ovides a tool to visualise the atmosp.ere conditions within the f.rnace and to exp.ore the ef.ects of.changing some of.the variables. Modelling the atmosp.ere in a typ.cal CAB f.rnace has shown the imp.rtance of.the integrity of.the curtains in maintaining the low oxygen levels required f.r successf.l Nocolok brazing. f.r a given set of.curtains it has shown that the only ef.ective way of.decreasing oxygen levels is to increase atmosp.ere gas f.ow.

Although cold treatments have been used to reduce the retained austenite in the cases of.carburised steel f.r many years, there is little data on deep.cold temp.ratures below -70℃ or treatment times longer than an hour or two. This study set out to determine the ef.ects of.such deep.cold treatments at temp.ratures -150℃ f.r 24 h. The study investigated the ef.ects of.deep.cold on the microstructure, hardness p.of.le, residual stress and internal oxidation on two typ.cal carburising steels, 16MnCr5 and 21NiCrMo2. The study f.und that f.r both 16MnCr5 and 21NiCrMo2 carburised to a case dep.h of.ap.roximately 0.8 mm, the longer and colder the deep.cold treatment, the more the austenite retained in the case was converted to martensite and the harder it became. Af.er low temp.rature temp.ring, the hardness dif.erence was smaller, but still signif.cant. In both steels, the case ap.eared more ref.ned and homogeneous af.er deep.cold treatment. Deep.cold treatment had a negligible ef.ect on the core p.op.rties of.either steel.

Objective:To rep.rt the p.evalence of.ap.endiceal disease in women with chronic p.lvic p.in undergoing lap.roscop. f.r p.ssible endometriosis,summarize the literature,and more accurately estimate the p.evalence of.endometriosis of.the ap.endix. Design:p.osp.ctive case series and literature review. Setting:Academic research institute. p.tient(s):One hundred thirty-three p.tients with chronic p.lvic p.in and p.ssible endometriosis undergoing lap.roscop.. Intervention(s):History,p.ysical exam,and abdominop.lvic lap.roscop.. Endometriosis and adhesions were excised using selective Nd:YAG contact laser trabeculop.asty and p.thologically evaluated. Only p.tients with visible abnormalities involving the ap.endix were treated via concurrent lap.roscop.c ap.endectomy. Main Outcome Measure(s):Ap.endiceal abnormalities at lap.roscop.. Result(s):Of.133 p.tients,13 had a p.evious ap.endectomy with unknown p.thology. Of.the remaining 120 p.tients,109 rep.rted right lower quadrant p.in. Of.this subgroup.six p.tients had ap.endiceal p.thology:f.ur with p.thology-conf.rmed endometriosis,one with Crohn’s disease susp.cted at lap.roscop.,and one with chronic ap.endicitis. The p.evalence of.ap.endiceal endometriosis in p.tients with biop.y-p.oven endometriosis (n = 97) or with right lower quadrant p.in (n = 109) was 4.1%and 3.7%,resp.ctively. This rate was similar to the 2.8%p.evalence conf.rmed by literature review in p.tients with endometriosis but was much higher than that rep.rted in all p.tients (0.4%). Conclusion(s):Ap.endiceal endome- triosis,while relatively uncommon in p.tients with endometriosis,is rare in the general p.p.lation. In p.tients with right lower quadrant or p.lvic p.in,the ap.endix should be insp.cted f.r endometriosis and evidence of.nongynecologic disease.

BACKGROUND: Squamous intraep.thelial lesions are more p.evalent in women inf.ctedwith the human immunodef.ciency virus(HIV) comp.red with immunocomp.tent women. Loop.electrosurgical excision p.ocedure(LEEp. is commonly used to treat squamous intraep.thelial lesions because it may be p.rf.rmed as an outp.tient p.ocedure with minimal blood loss and a low comp.ication rate. CASE: We rep.rt a major inf.ctious p.st-LEEp.comp.ication in an HIV-inf.cted f.male who had an uneventf.l LEEp.in which a cellulose hemostatic agent was used. Desp.te the severity of.the inf.ction, she was successf.lly treated with a minor surgical p.ocedure along with broad antibiotic coverage. CONCLUSION: Although a cellulose hemostatic agent contaminated with p.rineal secretions may have served as a nidus f.r inf.ction, use of.p.riop.rative antibiotics or cervical cleansing should be considered to p.event sep.is in immunocomp.omised hosts.
