We obtain the necessary and sufficient conditions for the commutativity of k~-order slant Toeplitz operators and the compactness of products of such operators, in particular, the commutativity and the essential commutativity of such operators are in accord.

第二章研究了L~2上的k阶斜Toeplitz算子的性质、得到了两个k阶斜Toeplitz算子可交换的充要条件及其乘积和换位子是紧算子的充要条件，特别地，给出了两个k阶斜Toeplitz算子的交换性与本性交换性是一致的。

In the third chapter, we study the approximation and weighted approximation for a kind of generalized Baskakov operators of two-variable. Using different weight functions, we discuss the convergence on weighted space of polynomials and rate of convergence with Jacobi weight for this kind of two-dimensional product-type operators, which extends the results of one-dimensional operators.

第三章研究一类二元广义Baskakov算子的逼近及其加权逼近，主要针对于不同的权函数讨论了这类乘积型的二元算子及其导数在多项式权空间上的收敛性和加Jacobi权的收敛阶，把一元的结果推广到多元的情形。

As to how to avoid weaknesses of these two operators, scholars have made unremitting efforts. One of the most famous is the French mathematician Sablonniere P, who introduced and studied a kind of new quasi-Bernstein interpolation operators in 1992. This kind of operators have given dual attention to the Lagrange operator and the Bernstein operator merit, and have avoided the twos deficiency.

对于这两种算子如何扬长避短，学者们做了不懈努力，其中最为著名的是法国数学家Sablonniere P，他于1992年引入并研究了一种新的拟Bernstein插值算子B上标(k 下标 n，，这是一类介于Lagrange算子与Bernstein算子之间的拟插值算子，这类算子兼顾了Lagrange算子与Bernstein算子的优点，克服了二者的不足。

Sub-Contractor' Includes owners and operators of any vessels, stevedores, terminal and groupage operators, road, rail and air transport operators and any independent contractor employed by the Carrier in performance of the Carriage and any sub-sub-contractors thereof.

转包商' 包括货主和任何船只的操作者，搬运者，码头和化零为整的货箱操作者，公路，铁路和空中运输操作者以及任何一个独立的由承运商雇佣的条约签订人，和其他转包商的转包商。

"Sub-Contractor" includes owners and operators of vessels, stevedores, terminal and groupage operators, road and rail transport operators, longshoremen, warehousemen and any independent contractor employed by the Carrier in performance of the Carriage.

"分包商"包括运送人以外的船东和船舶代营公司、码头装卸工人、货柜场和并装货物业者、公路和铁路运输人员、船边作业人员、仓库工作人员和运送人在履行货载运输中所雇佣的任何独立承包商。

"Sub-contractor" includes owners and operators of vessels, stevedores, terminal, warehouse, depot and groupage operators, road and rail transport operators and any independent contractor employed by the Carrier in the performance of the carriage and any sub-sub-contractor thereof.

"分立契约人"（SUB-CONTRACTOR）包括船舶所有人及经营人，装卸工人，码头、仓库、集装箱储运站经营人及拼箱经营人，公路及铁路运输经营人，及承运人雇佣的用以进行运输的任何独立订约人，以及其小分立契约人（SUB-SUB-CONTRACTOR）。

The research of this thesis focuses on the infimum and supremun of self-adjoint operators in a complex Hilbert space with respect to the Gudder order, the infimum and supremun of operators in a complex Hilbert space with respect to the *-order and theΓ-inverse of operators in a complex Hilbert space.

本文研究内容涉及Hilbert空间上自伴算子关于Gudder序的上确界和下确界，Hilbert空间上算子关于~*-序的上确界和下确界以及Hilbert空间上算子的Γ-广义逆这三个方面的内容。

The bitwise operators and logical operators use the same characters, so it is helpful to have a mnemonic device to help you remember the meanings: since bits are "small," there is only one character in the bitwise operators.

按位运算符和逻辑运算符都使用了同样的字符，只是数量不同。因此，我们能方便地记忆各自的含义：由于"位"是非常"小"的，所以按位运算符仅使用了一个字符。

One end is the substantial use of the third person form, the present tense and the past tense; through frequent use of the third person form as the Subject, the writers of commercial editorials are at a position of an impartial third party describing the facts in an apparently neutral manner; the past tense and the present tense are also considerably employed to further help to enhance the objectivity of the writers" presentation, for they reflect the facts and events which did take place and do stay there now. The other is the moderate employment of modal operators and Modal Adjuncts. Those of low value group and median value group form the main body of all the modal operators; instead modal operators of high value group occur least frequently, which imply writers" strong attitude.

为得到更有普遍性更可信的结论，本文作者选取了30篇商业社评作为大样本进行统计处理、描述及分析；通过对语气成分及情态修饰语的分析，探讨了在商业社评中人际功能与非人际表现的平衡；一方面是大量使用第三人称、现在时态与过去时态，另一方面是应适度采用情态算子与情态修饰语。
