针对电场积分法部分节点过于靠近导线、积分域划分不便于计算等问题,该文提出一种给定节点的Gauss型数值积分方法,从而降低非线性方程的求解难度,优化积分节点参数,提高电压测量精度。首先,结合空间电场数值积分法原型,建立给定节点的Gauss型积分方法计算模型,推导出含电场扰动因素的节点参数解析式;然后,利用Maxwell电磁仿真软件计算三相输电线路下方的电场分布情况,结合积分节点选取的限定因素,计算出节点坐标与对应权值;最后,搭建D-dot传感器测量实验平台检验所提出电压测量方法的有效性。根据5~20 kV电

Q熊老师您好!有些驾驶员主动要求关闭奥迪车的自动启停功能,说使用中有些不习惯3但是,关闭后,有时车辆会发生一些异常状况,如启动困难或熄火,请问该怎么辨别启动或熄火现象与关闭启停系统相关,是正常的,或者与关闭启停系统无关,是故障呢?
The contribution reflects on the crucial role that the body assumes in the context of the posthuman need/process of integral redefinition of the notion of the human.And,dialoguing,so to speak,even with positions from contemporary philosophical thought,suc
It has been recognized that self-reliance and self-improvement of science and technology is a necessary choice of taking the independent innovation path with Chinese characteristics in the new era,which provides strategic support for the comprehensive con
The paper starts examining some ideas of Einstein and Rovelli about space and spacetime in the context of the general theory of relativity and identifying a connection among them.I continue drawing a parallel between those ideas in the field of physics an

In the context of professional technical education,dual modality has been a commitment of the Chilean Ministry of Education to improve professional technical training in high school.The change has involved a curricular innovation around the development of
Ecological justice is a good state of symbiosis and sharing between man and nature on the basis of labor.Based on historical materialism,Marxs concept of ecological justice takes labor as the intermediary of the relationship between man and nature,and exp
This is a paper about semantic holism.Semantic holism is a doctrine about the philosophically indispensable circumstances for something to have meaning.We therefore instigate our argument by endeavoring to view semantic holism in its philosophical context
笔者等在野外调查的基础上,对出露于滇西临沧岩浆弧北部凤庆箐头山地区原1∶25万凤庆县幅划分的二叠纪糜棱岩化黑云二长花岗岩进行了系统的年代学、岩石学和地球化学研究。该花岗岩体中,锆石具典型的振荡环带,Th/U值均大于0.2,为岩浆成因,其LA-ICP-MS U-Pb年龄为213±5 Ma,应当为岩浆结晶年龄,表明该岩体形成于晚三叠世,而非前人认为的二叠纪。全岩主微量元素分析结果显示,箐头山花岗岩Na2O/K2O值低,富Al2O3
利用岩芯、薄片、扫描电镜和分析化验等资料,对南堡凹陷南部深层古近系沙一段(沙河街组一段)优质碎屑岩储层特征进行了分析并揭示其成因机制。研究表明:(1)南堡凹陷南部沙一段优质碎屑岩储层属于低孔中渗储层,发育原生孔隙、次生孔隙和微裂缝;(2)沙一段沉积期处于强水动力沉积环境,辫状河三角洲前缘水下分流河道砂体普遍发育,岩性主要为中粗砂岩、含砾砂岩和砂砾岩等粗岩性,岩石类型主要为岩屑长石砂岩,石英、岩浆岩岩屑等刚性组分含量高,储层在强压实作用下仍保留了局部原生残余粒间孔,部分刚性组分强压条件下形成微裂缝;(3)沙
