【目的】揭示猫儿山自然保护区3种不同林分类型土壤有机碳储量差异及其剖面垂直分布特征,为该区域林业碳汇发展提供科学理论依据。【方法】以猫儿山水青冈天然次生林、毛竹人工林、杉木人工林3种典型林分作为研究对象,采用野外调查结合室内分析的方法,测定并计算各林分土壤容重、有机碳含量、有机碳密度和有机碳储量,并根据各林分结果数据来分析不同林分土壤有机碳储量差异及其剖面垂直分布特征和占比规律。【结果】不同林分类型土壤有机碳含量、有机碳密度及有机碳储量均表现为:水青冈天然次生林>毛竹人工林>杉木人工林。不同土层土壤有机碳含量、有机碳密度及有机碳储量存在显著差异,且均随土层加深有机碳含量等指标降低。水青冈林分土壤总有机碳储量最高,为332.99 t hm^(-2);杉木林分土壤总有机碳储量最低,为225.27 t hm^(-2)。有机碳储量占比也是随土层加深而逐渐变小,土层越深,占比越小。【结论】水青冈天然次生林土壤有机碳储量高于毛竹人工林、杉木人工林,有较好的碳储量积累与固定效应。

目的探讨肠易激综合征(irritable bowel syndrome,IBS)患者合并非酒精性脂肪性肝病(non-alcoholic fatty liver disease,NAFLD)的临床特征及危险因素。方法回顾性分析2020年6月至2023年6月于中国人民解放军总医院第六医学中心消化内科就诊的IBS患者,根据是否合并NAFLD将患者分为IBS-NAFLD组和IBS-非NAFLD组,比较两组患者的临床特征,包括一般临床资料、实验室检查结果和腹部症状,并用多因素Logistic回归分析筛选出IBS合并NAFLD的危险因素。结果共纳入145例IBS患者。其中IBS-NAFLD组78例(53.8%),IBS-非NAFLD组67例(46.2%)。多因素Logistic回归分析显示,年龄增长、BMI增加、高血压、TBA水平升高、TG水平升高、SIBO阳性是IBS合并NAFLD的独立危险因素。在腹部症状上,与IBS-非NAFLD组相比,IBS-NAFLD组的腹泻、腹胀、排气较多症状发生率显著增加(P0.05)。结论NAFLD在IBS患者中并不少见。年龄、BMI、血压、TBA水平、TG水平、SIBO是IBS患者合并NAFLD的独立危险因素。临床医师应重视对上述因素的控制,以减少IBS合并NAFLD风险的发生。

The effect of direct ageing treatment on microstructure and stress-rupture properties of GH761 alloy was studied. Phosphorus was added to the tested alloy for its beneficial effect on stress-rupture life. It was found that the grain size of the tested alloy became much finer after direct ageing treatment, in comparison with the commercial GH761 alloy under standard heat treatment condition. The optimum direct ageing treatment has been determined as follows： 830 ℃ × 4 h, air cooling＋ 720 ℃ × 24 h, air cooling. After such treatment, the higher stress-rupture prop- erties of the test alloy at 650 ℃, 690 MPa were obtained. The role of phosphorus is still effective under the condition of direct ageing treatment.
