飞机在服役中往往处于复杂多变的动载荷环境,动载荷定位是需首要解决的问题。本文针对飞机结构多种常见且易引起异常振动的动载荷定位需求,结合深度神经网络,建立了一种面向飞机结构的异常动载荷快速定位方法。采用长短期记忆(Long Short-term Memory,LSTM)神经网络构建可以精确描述结构所受动载荷的作用位置与振动响应间对应关系的逆向隐式函数模型,提出了基于LSTM神经网络分类模型的动载荷定位技术。建立了简化的全机结构有限元模型,对飞机在实际飞行中可能遇到的几个典型动载荷工况进行了模拟,准确完成了对动载荷的定位,并对所建立深度神经网络的抗噪性、鲁棒性进行了研究。仿真结果表明,所提方法对多种载荷工况下的动载荷位置可以进行准确识别,且在10 dB的测量噪声水平和2.8%的参数摄动下仍能保持较高的定位准确率。

Glyphosate-resistant crops have been a huge economic success for genetic engineering. The creating of new glypbosateresistant plants would increase the available choices for planting and lower the price of genetically modified crop seeds. A novel G6 gene from Pseudomonas putida that encoded 5-enolpyruvylshikimate-3-phosphate synthase （EPSPS） was previously isolated. The G6 gene was transfected into rice via Agrobacterium-mediated transformation. The transgenic rice obtained was confirmed by PCR, Southern, and Western blots. The lab experiment and field trials further confirmed that the transgenic rice can survive glyphosate spraying at a dose of 8 g L^-1. In contrast, conventional rice was killed at a weed control glyphosate spray dose of 1 g L^-1. Altogether, the present study showed that the G6 gene works well in rice in vivo for glyphosate-resistance.

关键词： transgenic rice glyphosate-resistance EPSPS

AIM： To investigate the effects of verapamil on nitric oxide （NO） synthesis in a portal vein-ligated rat model. METHODS： Systemic and splanchnic hemodynamics were measured by radiolabeled microspheres in portal hypertensive rats after acute administration of verapamil （2 mg/kg） on chronic treatment with N^W-nitro-L-arginine （NNA）（80 mg/kg） and/or indomethacin （2 mg/kg） . RESULTS： Verapamil （2 mg/kg） caused a marked fall in both arterial pressure and cardiac output accompanied by an insignificant change in the portal pressure and no change in portal venous inflow. This result suggested that verapamil did not cause a reduction in portal vascular resistance of portal hypertensive rats, which was similar between N^w- nitro-Loarginine-treated and indomethacin-treated groups. CONCLUSION： In portal hypertensive rats pretreated with NNA and/or indomethacin, acute verapamil administration can not reduce the portal pressure, suggesting that NO and prostaglandin play an important role in the pathogenesis of splanchnic arterial vasodilation in portal hypertension.

目的分析2012—2021年山东省县域道路交通伤害死亡率的时空聚集特征，为制定精准防制策略提供依据。方法利用山东省死因登记报告系统数据，计算交通伤害死亡率。分别采用Geoda 1.18和SatScan 9.7进行空间自相关和时空扫描分析以探索时空聚集特点，并运用主成分回归分析探索其影响因素。结果 2012—2021年山东省道路交通伤害死亡率总体呈下降趋势，秋季偏高。各年均存在空间相关性，“高—高”聚集区主要位于鲁中南和鲁西北。时空扫描显示全人群存在4个聚集区，一级聚集区存在于2012年3月至2015年2月，覆盖26个区县，主要位于鲁中南。城乡与总人群相似，均主要位于鲁中南，城市主要聚集区存在于2012年1月至2014年12月，覆盖19个区县；农村主要聚集区存在于2012年1月至2014年12月，覆盖38个区县。主成分回归分析显示，反映经济、交通情况的变量影响较大，其中常住人口数、客货运输量与死亡率呈正相关，其他呈负相关。结论 2012—2021年山东省道路交通伤害死亡率总体呈下降趋势。主要聚集区存在于鲁中南，且农村聚集更明显。提示应根据聚集性特征，关注高风险地区的法律执行、基础设施建设、人口流动等影响因素，因地制宜地采取或调整防控策略。

本文首先提出人民币汇率改革应明确一个前提:人民币汇率政策的目标是,使汇率服务于我国经济长期稳定增长的需要。在具体分析了人民币汇率与几大宏观经济目标的关系后,接下来阐述了人民币汇率改革的方向:一是在汇率形成机制上,随着我国金融体制改革的不断深化,逐步加大人民币汇率的浮动弹性,实现真正的以市场供求为基础的有管理的浮动汇率制度;二是在汇率水平上,与我国经济增长相伴随,实现人民币汇率水平的稳中有升。本文进一步探讨了人民币汇率改革的阶段性目标。最后,针对当前人民币汇率改革面临的问题,笔者提出了相关政策建议,以求实现更为合理的人民币汇率形成机制,从而为人民币汇率改革长期目标的实现打下基础。
