In former researches there are primarily theoretical studies and qualitative analyses on leaders 'effectiveness and performance, and there are a few studies on quantitative analyses, which mostly rely on the method of comparing differences and ratio of divergence to evaluate leaders' performance by stage statistics. 以往关于领导绩效和领导效率的研究,大多是理论研究或定性分析,个别的定量分析通常是通过阶段性统计数据的差异比较或差值比率。
When adding NES into cement, it can improve the cement paste divergence, accelerate cement hydration, densify hardened cement structure, enhance the compressive strength at early stage, entrain small pore, and improve hardened cement structure. 将研制出的NES高效减水剂应用于水泥,其对水泥颗粒有良好的分散作用;促进水泥水化,硬化后结构更加致密,早期强度得到提高;
The production mechanism of contemporary literature urges the divergence of popular literature and the pure literature, and "The 1970's Writers" who are charateristic of youth and fashion come to the stage quietly in 1990's. 转型期当代文学生产机制的变化促使大众化的畅销文学与小众化的纯文学之间的分流越来越明显,以青春、时尚为主要特色的70后便在20世纪90年代骤然兴起。
The infraed divergence theory of the revision and the two-level systems model is used to discuss the behaviour of ultrasonic absorption with the second stage nonlinear in metallic glass ( PdSiCu 、 PdSi and PdWiP) at 2K temperatures. 本文采用修正的红外发散理论和二能级体系(TLS)模型,讨论金属玻璃PdSiCu,PdSi和PdNiP在2K温度以下的第二次非线性超声吸收行为。
The warm core occurs, the cyclone vorticity increases and the divergence alternates with height in the middle-level at the forming stage of MCC, and the levels of ascending motion are thick. MCC在低空急流中心前方的风速梯度区中形成并发展;MCC形成阶段,中层出现暖中心并且气旋性涡度增大,辐合辐散运动随高度交替出现,量级相当,上升运动的层次较厚。
