We propose a simple method to investigate the crystallization kinetics of amorphous In44Sb20Te36 films on a nanosecond scale, based on local reflectivity measurements of the nanosecond laser-induced crystallization using a static tester. The pulse condition in terms of laser power and pulse width required for the onset of crystallization is established. Applying this pulse condition and Kissinger's analysis, an activation energy of 0.57eV is estimated for the crystallization. This value deviates substantially from the activation energy determined at lower sample temperatures where crystallization proceeds in a time scale of seconds rather than nanoseconds.

目的探讨血清免疫球蛋白(Ig)G4水平及IgG4/IgG比值在IgG4相关性疾病(IgG4-RD)的鉴别诊断及疗效观察中的应用价值。方法2020年8月至2023年2月于南方医科大学附属广东省人民医院就医并确诊的155例自身免疫性疾病患者作为研究对象,其中IgG4-RD患者60例(IgG4-RD组),其他疾病95例(其他疾病组,包括干燥综合征患者31例,血管炎患者19例,系统性红斑狼疮患者19例,强直性脊柱炎患者5例,类风湿性关节炎患者14例,斯蒂尔病患者3例,皮肌炎患者2例,系统性硬化症患者2例)。另选取50例体检健康者作为对照组。采用免疫比浊法检测各组标本血清IgG4、IgG水平,并计算IgG4/IgG比值。绘制受试者工作特征(ROC)曲线评价血清IgG4水平、IgG4/IgG比值鉴别诊断IgG4-RD的最佳cut-off值、灵敏度及特异度。比较IgG4-RD患者治疗前后IgG4水平、IgG4/IgG比值及其他实验室指标的差异。结果IgG4-RD组血清IgG4水平、IgG4/IgG比值均明显高于其他疾病组和健康对照组,差异有统计学意义(P<0.05)。ROC曲线分析结果显示,IgG4诊断IgG4-RD的最佳cut-off值为1.93 g/L,灵敏度为96.7%,特异度为86.2%,AUC为0.928;IgG4/IgG比值诊断IgG4-RD的最佳cut-off值为13.9%,灵敏度为90.9%,特异度为84.3%,AUC为0.933。经激素治疗前后,17例IgG4-RD患者血清IgG4水平及IgG4/IgG比值差异有统计学意义(P<0.05),其中有16例患者血清IgG4水平下降率大于IgG4/IgG比值。IgG4-RD组血清指标阳性率较高的3个指标是红细胞沉降率(ESR)、抗核抗体(ANA)、类风湿因子(RF)。其他疾病组中IgG4水平及IgG4/IgG比值较高的为皮肌炎组、强直性脊柱炎组、血管炎组。结论血清IgG4水平、IgG4/IgG比值对IgG4-RD患者有较高的诊断效能。经激素治疗后,IgG4-RD患者血清IgG4比IgG4/IgG比值下降更明显,但在其他自身免疫性疾病及健康人群中血清IgG4及IgG4/IgG比值也存在升高,需要结合其他指标综合判断。

This article reveals the ecological features and the theories and methods of introducing pioneer plants in the process of eco-restoring in different degenerative ecosystems in the drainage basin of Erlongshan Reservoir in Heilongjiang Province by systemically studying the deteriorative ecosystems and using recovery theory. The study shows that with the rise in degenerative degrees of the ecosystems, bio-species and bio-diversity sharply decrease in the study area and microclimate becomes warmer and drier in natural ecosystem. Therefore, we must attach importance to the construction of plants and biodiversity. In the study, different pioneer plants are selected for different degenerative ecosystems to restore and maintain the service functions of the ecosystems.

The applicability of a non-point source pollution model—SWAT(soil and water assessment tools) in a large river basin with high sediment runoff modulus(770 t/km2 in the Yellow River) was examined. The basic database, which includes DEM, soil and landuse map, weather data, and land management data, was established for the study area using GIS. A two-stage “Brute Force' optimization method was used to calibrate the parameters with the observed monthly flow and sediment data from 1992 to 1997. In the process of calibration automated digital filter technique was used to separate direct runoff and base flow. The direct runoff was firstly calibrated, and the base flow, then the total runoff was matched. The sediment yield was calibrated to match well. Keeping input parameters set during the calibration process unchanged, the model was validated with 1998—1999's observed monthly flow and sediment. The evaluation coefficients for simulated and observed flow and sediment showed that SWAT was successfully applied in the study area: relative error was within 20%, coefficient of determination and Nash-Suttcliffe simulation efficiency were all equal to or above 0.70 during calibration and validation period.
