【研究目的】文章旨在通过分析狮溪地区狮溪1井五峰组—龙马溪组页岩成藏要素,揭示黔北地区复杂构造区页岩气成藏条件,查明黔北地区五峰组—龙马溪组页岩气成藏潜力。【研究方法】本次研究基于黔北地区狮溪1井的系列钻井取心、测井曲线、地震资料、地化测试以及储层特征等综合实验分析,围绕“生—储—保”三个维度开展页岩气成藏综合研究。【研究结果】狮溪1井五峰组—龙马溪组富有机质页岩厚度约25 m,TOC含量分布在2.79%~4.77%,等效镜质体反射率为2.01%~2.59%,有机质类型以I型为主,具有良好的生气基础;富有机质页岩层段脆性矿物含量较高,平均值约为61.05%,具有较高的脆性;发育大量微纳米级孔隙,主要为有机质孔、无机—有机质复合孔,孔体积以及比表面积参数表现良好,为页岩气的赋存提供了良好的储集空间;残留向斜内部富有机质页岩段顶底板具有较好的封闭能力,三者纵向上形成良好的生储盖组合;狮溪1井东部与西部发育两条通天断裂,距离断层较远的同时,得益于断层较好的封闭性以及平缓的地层产状,狮溪1井因而具有良好的含气显示。【结论】黔北地区残留向斜内部五峰组—龙马溪组页岩同样具有页岩气高效、规模建产的油气地质条件,是下一步勘查与攻关研究的重点方向。该成果扩大了页岩气勘查范围,拓宽了四川盆地周缘页岩气勘探深度和广度,有望形成新的资源接替区。

目的构建对急性主动脉综合征(AAS)诊断具有较高预测价值的AAS风险分层评分(AAS-RSS)。方法回顾性收集2019年8月至2022年7月在济宁医学院附属医院急诊科就诊怀疑AAS患者共630例,根据AAS诊断标准将患者分为AAS组和非AAS组,其中AAS组346例,非AAS组284例。采用二分类logistic回归分析法分析AAS的独立危险因素,构建AAS-RSS,绘制ROC曲线对AAS-RSS进行评价。结果 AAS组男性、高血压病、突发胸背部痛、撕裂样或刀割样疼痛、疼痛评分≥5分、持续无缓解、大汗、呼吸困难、呕吐、动脉搏动消失或无脉、四肢血压差异明显、新发主动脉瓣杂音、低血压或休克、D-二聚体、C反应蛋白,合并心包填塞、肠功能障碍、急性肾损伤发生率高于非AAS组,差异有统计学意义(P<0.05)。AAS组深吸气或咳嗽诱发、针刺样疼痛、心悸、合并急性心肌梗死发生率低于非AAS组,差异有统计学意义(P<0.05)。logistic回归分析结果显示,男性、突发胸背部痛、撕裂样或刀割样疼痛、心悸、动脉搏动消失或无脉、D-二聚体、C反应蛋白、合并急性心肌梗死是AAS发生的影响因素(P<0.05)。根据logistic回归分析β值大小及结合ADD-RS(主动脉夹层检测风险评分),共有23个变量被有效整合成AAS-RSS。AAS-RSS分值高低与AAS的发生呈正相关(r=0.72,P<0.05)。AAS-RSS、ADD-RS预测发生AAS的曲线下面积分别为0.919(0.898~0.941)、0.734(0.694~0.773)。AAS-RSS约登指数最大值为0.699,截断值为8.5分,AAS-RSS评分9分为区分高危AAS和低危AAS的界值。AAS-RSS识别高危AAS的灵敏度、特异度分别为89.3%、80.6%;ADD-RS识别高危AAS的灵敏度、特异度分别为85.0%、52.5%。结论 AAS-RSS对AAS风险分层具有较高预测价值。

Most of the existing PID parameters tuning methods are only effective with pre-known accurate system models, which often require some strict identification experiments and thus infeasible for many complicated systems. Actually, in most practical engineering applications, it is desirable for the PID tuning scheme to be directly based on the input-output response of the closed-loop system. Thus, a new parameter tuning scheme for PID controllers without explicit mathematical model is developed in this paper. The paper begins with a new frequency domain properties analysis of the PID controller. After that, the definition of characteristic frequency for the PID controller is given in order to study the mathematical relationship between the PID parameters and the open-loop frequency properties of the controlled system. Then, the concepts of M-field and θ-field are introduced, which are then used to explain how the PID control parameters influence the closed-loop frequency-magnitude property and its time responses. Subsequently, the new PID parameter tuning scheme, i.e., a group of tuning rules, is proposed based on the preceding analysis. Finally, both simulations and experiments are conducted, and the results verify the feasibility and validity of the proposed methods. This research proposes a PID parameter tuning method based on outputs of the closed loop system.

Linear thermal expansion coefficient （TEC） of Ti bulk is investigated by means of molecular dynamics simulation. The elastic minimum image convention of periodic boundary conditions is introduced to allow the bulk to adjust its size according to the new fixed temperature. The TEC and the specific heat of Ti are compared to the available theoretical and experimental data.

Objectives: To explore the perioperative nursing care for lung cancer patients undergoing total pneumonectomy, and to promote their rehabilitation. Methods: We will provide preoperative assessment and education in the aspects of respiratory function, diet, and psychology to patients undergoing total pneumonectomy, and provide continuous postoperative management about posture, fluid, and respiratory to help patients diagnosed with lung squamous cell carcinoma and underwent total pneumonectomy to reduce their postoperative complications and improve their overall quality of life. Results: 78.9% of lung cancer patients who underwent total pneumonectomy achieved a better outcome and prognosis by receiving the above nursing program. Conclusion: With large lung cancer tumors, the surgical trauma is highly invasive and the resection is extensive. Management of the patient’s respiratory tract is the focus of perioperative nursing and the key to preventing the development of related postoperative complications.

AIM： To evaluate the visual, refractive and corneal asphericity changes after intrastromal corneal ring segment（ICRS） implantation for visual rehabilitation of ***： A total of 42 eyes of 32 patients were included. After creation of intrastromal tunnels of 5.01±0.03 mm inner diameter, 5.71±0.03 mm outer diameter and at 384.21±34.12 μm depth, 1 or 2 ICRS of 150-300 μm thickness and 90°-210° arc length were implanted. Changes in uncorrected distance visual acuity（UDVA）, corrected distance visual acuity（CDVA）, refractive errors, mean simulated keratometry readings SimK_（avg）, anterior and posterior corneal asphericity values（Q_（ant） and Q_（post）, respectively） measured with Scheimpflug topography were evaluated retrospectively. RESULTS： There was a significant improvement in UDVA and CDVA, along with a significant decrease in refractive spherical equivalent（SE）, cylinder and SimK_（avg） postoperatively（P〈0.001 for all）. Mean Qant increased from-1.06±0.48 to-0.57±0.58 postoperatively（P〈0.001）. Change in mean Qpost was insignificant（P=0.92）. Postoperative changes in UDVA and CDVA were not correlated with the postoperative changes in SE and cylinder（P〉0.05 for all）; but were correlated with the preoperative SimK_（avg） and Q_（ant） values（P〈0.001 for all）. CONCLUSION： ICRS implantation seems to approximate the anterior corneal asphericity of ＂advanced prolate＂ shape to ＂optimal prolate＂ shape and an ＂ideal Q value＂ of-0.46; which may have a role in improved UDVA and CDVA postoperatively, besides decreased refractive cylinder values.

The structure and thermal parameters of Ni20Pd80 alloy were studied by X-ray diffraction（XRD）. The diffraction experiments performed in the temperature range of 308-1100 K revealed that the alloy formed a face centered cubic （fcc） Al-type structure. The temperature dependence of the lattice parameters was investigated by using the Bragg line displacement method showing that the lattice parameter increases with the increase of temperature. The mean linear thermal expansion （MLTE（%））, coefficient of thermal expansion （CTE, α）, the characteristic Debye temperature （（θD） and mean square amplitudes of vibration were determined from XRD data. The value of Debye temperature was found to be 253 K. It was found that temperature factor was independent of the static displacements.
