They are rule - liked modes and represent the site officers " market strategy thinking . based on the above - mentioned , the paper puts forward different recommendation strategies which suit both registered users and non - registered users , produces some recommendation formulae on computing a item ' s recommendation value to a user and related algorithms 基于这些模式，论文提出了针对站点注册用户和非注册用户的不同推荐策略，并产生了相应的某物品对于当前用户推荐值的推荐计算公式以及相应的推荐算法，由此得到针对某个用户的推荐。
Sponsered by hunan provincial communications department , a great in - site static pile test is carried out for the maocaojie bridge , which is introduceded in details in this paper . from the test , some results with value of theory and practice are obtained about the axial laod capacity of large - diameter bored bridge piles in the area of dongtinghu lake 详细分析了洞庭湖区大直径桥梁基桩的受力特性，并提出了可供实际工程应用的洞庭湖区大直径桥梁基桩桩侧摩阻力推荐值，指出了桥梁基桩的设计中应注意的问题。
It also calculates theoretically the minimal time interval between two trains in quasi - moving - block signaling system and recommends approximate values for the length of coded digit track circuit . the rapid development of urban rail transit demands a deep understanding on the features of track circuit 在此基础上，针对当前应用广泛的基于数字轨道电路的准移动闭塞atc系统进行了重点分析，详细讨论了数字轨道电路的原理、准移动闭塞系统的列控方式等内容，并对准移动闭塞下的最小列车追踪间隔时间进行了理论计算和分析，给出了数字轨道电路长度的推荐值。
The influences of soil structure , confining pressure and strain amplitude on dynamic properties of recently deposited soils of nanjing and its surrounding areas are discussed . furthermore , based on test results and theoretical analysis , the averaging curves , recommended values and envelopes of dynamic shear modulus ratio ggmax and damping ratio versus dynamic strain for recently deposited soils of nanjing and its surrounding areas are presented . by use of vibration triaxial apparatus , nanjing silty clay and fine sand interbedded strata and nanjing fine sand were tested and their test results are discussed 通过自振柱试验，探讨了土的结构性、有效围压和应变幅值大小对动荷载作用下南京及其邻近地区新近沉积土的动剪切模量、阻尼比和应力?应变关系的影响；通过试验和理论分析，给出了南京及其邻近地区的粘土、淤泥质粉质粘土、粉质粘土、粉质粘土与粉砂互层土、粉土以及砂土等六类新近沉积土中典型土类的动剪切模量比和阻尼比随剪应变幅值变化的平均曲线、包络线和推荐值。
