Policy Studies Journal, Volume 54, Issue 3, August 2026.ABSTRACT Despite extensive research on policy diffusion, the ways in which policy attention influences this process remain underexplored. This study addressed this gap by distinguishing between three types of policy attention—political speeches, policy issuance and field visits—and investigating their differential impacts when delivered by central and ...

Dianci bileiqi, 2019 为了解双端接地时影响二次电缆芯线-屏蔽层电位差的各参数作用大小,及其各参数与芯线-屏蔽层电位差之间的线性程度,通过Matlab编程对电缆芯线-屏蔽层电位差进行计算分析,将二次电缆芯线-屏蔽层电位差作为目标函数,在函数定义区间内进行各个参数灵敏度分析。计算表明:接地网导体间距参数灵敏度较大,对芯线-屏蔽层电位差的影响作用最强,两者变化情况呈非线性关系,是优化设计的主要考虑因素;地网边长、电缆长度的参数灵敏度系数相对较小,可以在合理的范围内改变这两个参数进行优化,但效果不大;土壤电阻率参数灵敏度较小,芯线 ...

Policy Studies Journal, Volume 54, Issue 3, August 2026.ABSTRACT This study introduces a dual‐layer protocol for diagnosing how formal institutional designs are implemented in practice in complex governance systems. The protocol builds two linked process maps; one for the formal rules and procedures (rules‐in‐form) and one for the routines actors actually follow in practice (rules‐in‐use).

四川大学学报. 自然科学版, 2008 首先求Na-Na、K-K相同原子间Born-Maye势参数,利用TT势模型和边界条件,从色散系数、势阱位置与深度出发,导出Na、K与Ne不同原子间的势参数,再从Na-Ne、K-Ne原子系统出发,利用组合规则计算出Na、K相同原子间的势参数;然后研究Li-He、Na-He、K-He原子系统,利用电荷密度重叠积分与组合规则,从相同原子间势参数计算不同原子的势参数.最后采用TT势模型构成Li、Na、K原子与He原子间的全程势能曲线.

Shuitu Baochi Xuebao, 2018 为研究花岗岩崩岗土体水分特征曲线及其影响因素，以福建省安溪县崩岗崩壁土为对象，通过压力膜仪对土体进行脱湿试验，绘制出崩壁土体水分特征曲线，并进行曲线参数与影响因素的相关分析。结果表明：随崩壁土体垂直深度增加，崩岗土体塑性指数、黏粒含量、分形维数及磨圆度等均整体呈降低的趋势；水分特征曲线斜率随着深度的增加而增大，土壤持水能力减弱，残余含水率及VG模型参数a却随之减小，而参数n却随之增大；残余含水率、参数（a、n）均与容重和颗粒的磨圆度呈极显著相关；残余含水率可用容重和黏粒含量描述 ...
