1) multi-level user
多层次用户
1.
And on the basis of it, a multi-level user oriented visual experiment environment, which is named VCDS, is developed by using of C + + template technology and Windows COM/DCOM technology.
据此利用C++模板技术与Windows 的COM/DCOM技术实现了一个面向多层次用户的可视化数据结构实验环境VCDS。
2) User hierarchy
用户层次
4) user interest hierarchy tree
用户兴趣层次树
1.
Namely,the principle of Zipf distribution is introduced to find out the latent semantic space of files,where the user interest is clustered according to underlying factors and a user interest hierarchy tree is built in.
即先通过Zipf分布原理找到文档的潜在语义空间,在此空间中对用户的兴趣进行聚类,并建立用户兴趣描述文件(user profile),即建立用户兴趣层次树。
5) multi-level generic pieces
多层次通用件
1.
With the recursive traversal,non-recursion traversal and level traversal methods of BOM(Bill Of Material) and its wide use of multi-level generic pieces and complex structure,this paper proposed an improved algorithm checking the overlaped nest and the legitimacy,which integrated the basic theory of DAG (Directed Acyclic Graph) chart and the practical net structure of BOM.
结合物料清单(BOM)递归遍历、非递归遍历和层次遍历方法,针对多层次通用件的广泛适用构成的复杂产品,将实用性较强的网状BOM构造方法和无向无环图(DAG)的基本理论相融合,提出了一种新的BOM嵌套检查及合法性检查改进算法。
2.
To resolve the problem of duplication and omission which is associated with the multi-level generic pieces,based on the idea of lower-level code as LLC,an improved traverse algorithm of the BOM is put forward.
针对实际应用中多层次通用件计算的重复和遗漏问题,基于低层码LLC的思想,改进了BOM遍历算法。
6) User Layer
用户层
1.
Implementation of user layer protocol is helpful for the development of digital and intelligent automatic control system.
基于基金会现场总线标准的用户层协议的实现有助于开发面向仪器、仪表等控制设备的应用 ,促进我国自控技术的数字化、智能化进程 。
补充资料：多层次三原色印花
多层次三原色印花 利用染料的三原色，通过采用连续雕刻法（通称为影写版法）雕刻的浅花筒，在滚筒印花机上叠色印花，从而获得色泽鲜艳、多种层次、类似拍摄花卉印花效果的一种印花工艺方法。这种工艺印花方法要求织物表面平细，否则效果不佳。
