Ownership Structure of Listed Companies and EVA:An Empirical Study Based on Automobile Industry [PDF]
, 2016 股权结构与公司绩效的关系一直都被理论界和实务界所关注，这主要是由于公司股权结构与公司治理机制之间存在紧密联系，而公司治理机制的有效性最终体现在公司绩效上。不同的股权结构代表不同的权利与利益的分配，不同性质及持股比例的股东在企业中的地位与投资目的不同，会使治理机制发挥不同的作用而表现出不同的绩效，所以，股权结构与企业绩效息息相关。然而，目前国内外学者对两者之间的关系尚未得出一致结论。 汽车制造业与其他行业有着较强的关联性，并且极大地带动了居民消费，对于我国经济、社会发展具有重要影响 ...

Research of Total Alkalinity Online Monitoring and Control System [PDF]
, 2016 总碱度是锅炉水处理过程中的一项重要指标，为保证锅炉的安全运行，需要对锅炉水总碱度进行精确测量并随时了解锅炉水中碱度的情况。目前，锅炉水总碱度的监测一般采用传统滴定的方法，即人工移取水样后再进行滴定的方式，但该方法不仅劳动强度大，还具有错误率较高、效率低下、管理混乱等问题，对安全生产也会产生一定的影响。针对以上问题，本文研究了一种对锅炉水总碱度进行自动测算、数据传输以及监控的总碱度在线监测和控制系统。 为了满足锅炉水总碱度自动测算和远程监测的需求，本文建立了锅炉水总碱度在线监测和控制系统 ...

Optimized Copper Distribution and Enhanced Coercivity in PrO2‐Doped Sm2Co17‐Type Magnets
Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT A rational design of Cu distribution is crucial for achieving optimal magnetic properties in Sm2Co17‐type magnets. In this study, nanostructured PrO2 powders were employed to induce Cu redistribution at grain boundaries while preserving the cellular microstructure. The corresponding coercivity (Hcj), remanence (Br), and maximum energy product (
