Based on a brief review on developments of number system, a new developed pattern is proposed. The quaternion is extended to a matrix form aI+bA+cB+dC, in which the identity matrix I and three special matrices A, B, C correspond to number 1 and three units of imaginary number i, j, k, respectively.

在数系发展的基础上，提出了一种新的发展模式：四元数推广为矩阵形式aI+bA+cB+dC，其中单位矩阵I和3个特殊矩阵A，B，C分别相应于数1和虚数单位i，j，k。

A new graph theory methodology is presented for analysis of the unsteady flows in open channel network, including the structure and characteristics of the incidence matrix A, continuity equation and energy equation with matrix A.

提出了新的渠网非恒定流图论原理，包括适应渠网非恒定流特征的节支关联矩阵A的构建方法及性质分析，基于A的节点连续性矩阵方程和节点水深矩阵方程等。

A.Ownership is established by the Government Register b.Ownership is documented by reference to a good chain of title c.Registration provides an "indefeasible" title d.Owner is the person on the register e.Persons who lose their interests through fraud are protected by an insurance fund 9.The case of Mabo v The Queen (1992) is important because it deals with: a.

a.ownership政府登记成立 b.ownership记录了一系列关于良好标题 c.registration为"不可"称号 D.owner是人登记 e.persons丧失权益受到诈欺保险基金 9.the案判决(1992)5女王很重要，因为它涉及： A。

On the characterizations of spaces by the infinite matrix methods,let E be a topo-logical vector space,if for each 〓 and 〓,there is a sequence 〓 in A suchthat 〓.Then E is said to be a sequential topological vector space.

在无穷矩阵方法对空间的刻划方面，设E是一个拓扑向量空间，若对每个〓一定存在A中序列〓使得〓，那么称E是一个序列型拓扑向量空间。

In the data acquisition system, CD4051 and AD574- the A/D transform, are used as hard core to receive the signal from the infra-red ray temperature sensor; the data acquisition depend on CPU; in the keyboard/ display system, a 74LS48 as the driver to drive LED works; in the warning circuit, I used two color LED and a buzzer as one unit to work; DAC0832 converter is the center of the D/A transform; execution unit, I used DDZIII type electromotive unit; the auto-man, it is a disabling of the other control circuit, this can secure production all the time.

在数据采集部分，以多路开关CD4051和AD574模/数转换器为核心接收来自红外线传感器的信号；数据处理依赖CPU；键盘/显示部分，以74LS48驱动LED数码管工作；报警单元，采用了双色LED加蜂鸣器的组合；D/A转换采用了DAC0832转换器；执行器采用DDZIII型电动执行器；手/自动切换装置则屏蔽了之前的电器部分，安全可靠。

Unlike the over-50% category, all items of revenue and expense are omitted; just the proportional share of net income is included. Thus, if Corporation A owns one-third of Corporation B, one-third of B's earnings, whether or not distributed by B, will end up in A's earnings. There are some modifications, both in this and the over-50% category, for intercorporate taxes and purchase price adjustments, the explanation of which we will save for a later day. We know you can hardly wait.

因此如果A公司拥有B公司三分之一的股权，则不论B公司是否将年度盈余全数发放，A公司都必须依比例认列投资利益，另外这两类的会计原则都规定，必须附带一些企业间所得税、购买法价格调整等调整分录，这部份的细节请容我们以后有空再详加说明，(虽然我知道大家可能等不及了)。

Let f be a continuous function on the interval［a,b］, then it can reach its maximum and minimum on［a,b］.

设f是区间［a，b］上的连续函数，则f在［a，b］上达到它的最大值和最小值。

These accounts differ from intuitionist semantic anti-realism by providing a way to distinguish the inferential significance of "A" and "A is warranted."

这样的处理不同于直觉主义者的语义学反实在论，因为它提供了二种方式，使得我们可以阪分"A"和"A得以保证"的推理意义。
