Based on the projection theorem in the finite-dimensional inner product space, by making use of the generalized singular value decomposition and the canonical correlation decomposition of matrix pair simultaneously, we transform the least-squares problems of the abovementioned inconsistent matrix equations into the problems of solving the consistent matrix equations over given matrix set, and obtain the general expressions of the corresponding least-squares solutions.

S使得‖-X~*‖=‖-X~*‖，其中‖·‖为Frobenius范数，S分别表示矩阵方程 AXB=D，AXA~T+BYB~T=D，AXB+CYD=E和矩阵方程组=，=在一般矩阵集合或对称矩阵集合上不相容时的最小二乘解集合。

In this paper, two partition models are built to formulate the document collection partition problem from the essence of the problem itself and they can be used as the evaluation criterion of the document collection partition problem.

从文档集合划分问题本身出发，给出了两个划分模型来刻画文档集合划分问题，从而使这两个模型可以作为文档集合划分的有效评价指标。

A basic fact about sets is that there are two sets only when their memberships differ. The membership of the set of things that are phlogiston is exactly the same as the membership of the set of things that are Devil-dealing Salem witches. In each case, there are none. So in each case the set of instances is the set with no members, the null set.

按集合观，不承认这里有不同的共相，因为基础事实是，两个集合不同当且仅当成员不同，而这两个集合是相同的，因为都是没有成员的集合，即空集。

In this paper,we propose a new vers ion-control set refreshing algorithm,which adopts the mechanisms of incre mental maintenance,version control and batch processing to ensure on-line maint e nance and consistency.

本文提出了一种版本控制集合刷新算法VSRA，它采用增量维护和批处理思想，首先根据原始数据的变化集合，计算出实体化视图的刷新集合，然后据此集合刷新实体化视图，同时利用版本控制保持数据仓库与当前数据库状态的一致性，达到对数据仓库联机维护的目的。

In this set system, the set element named quorum is a set of points, and every two quorums intersect.

在这种集合系统中；所有集合元素都是节点的集合，任何两个quorum都有交集。

This invention relates to a method for inviting users on-line used in conference services including: 1, in a process of setting up conversation between a first user device and a second user device, the first one gets the route set for transmitting signaling when having conversation between them and registers it, 2, the first device transmits a request to the second device with a new conversation ID to a service device to ask the second device to take part in the meeting, when the route set is not empty, the first device adds the registered route set to the route set of the request, 3, the service device and the second user device are connected for the conversation.

根据本发明的用于会议业务的在线用户邀请方法包括以下步骤：步骤S302，在第一用户设备与第二用户设备建立会话的过程中，第一用户设备从传输的消息获取第一用户设备和第二用户设备进行会话时传送信令的路由集合并记录路由集合；步骤S304，第一用户设备以新会话标识向会议业务服务设备发送对第二用户设备的请求消息以请求第二用户设备加入会议，在路由集合非空的情况下，第一用户设备将所记录的路由集合加入到请求消息的路由集合中；步骤S306，会议业务服务设备与第二用户设备进行会话连接。

Experimental results show that the 3D SPEZBC algorithm has the same rate-distortion performances of three-dimensional embedded zero block coding (3D EZBC) algorithm, obviously outperforms three-dimensional set partitioned embedded block (3D SPECK) algorithm, three-dimensional set partitioning in hierarchical trees(3D SPIHT) algorithm and (AT-3D SPIHT) algorithm, and is slightly better than JPEG2000 multi-component (JPEG2000-MC) algorithm at different bit rate in the compression performances.

实验结果表明，3D SPEZBC算法具有与三维嵌入式零块编码(3D EZBC)算法相同的压缩编码性能，在各比特率下编码性能均明显优于三维集合分裂嵌入式块编码(3D SPECK)、三维等级树集合分裂(3D SPIHT)和非对称三维等级树集合分裂(AT-3D SPIHT)算法，并且略好于多分量JPEG2000编码(JPEG2000-MC)算法。
