The design method is described, and the calculation results are presented under the standard air conditioning condition. The working process of the two-stage expander is discussed, and the difference between the two-stage expander and the conventional one is stated. In addition, the influence of the dip angle on the expansion chamber volume is analyzed. The results show that the dip angle has little effect on the expansion chamber volume and it is suggested that the effect may be neglected in the expander design.

介绍了该膨胀机的设计方法，给出了标准空调工况下的计算结果，详细讨论了两级旋叶式膨胀机的工作过程，并对两级膨胀机与传统旋叶式膨胀机的区别进行了论述，最后分析了滑片倾角对工作腔基元容积的影响，结果显示，滑片倾角对工作腔基元容积的影响很小，在膨胀机的设计过程中忽略滑片倾角的影响是合理可行的。

Taking customer domain for example, an ontology-based customer metadata model is build and formalized in description logics. Then two kinds of modes for customer information sharing are studied. The two modes are to construct a global c ustomer m etadata m odel w ithin a n e nterprise a nd t o c onstruct a mapping mechanism between customer metadata models located on different enterprises respectively. In the first mode, an information source is regarded as a 3-tuples, including a metadata model, a concept relation set and a resource data set.

On the base of mean function of n variables of paper [1], weproof that is mean function and discuss its monotonicity andcontinuity.

第一部分是引言，主要介绍了一些已有的结果，如：一般的两个变元的Leach and Sholander均值B以及它的单调性，又介绍了文[1][4]中一些已有的结果，第一章主要介绍了一维n元平均函数和平均族，在已有的文[1]中给出的参差域K上的n元平均函数概念的基础上，证明一般形式的是平均函数，讨论了它的单调性和连续性，其中还将已有的二元Stolarsky平均推广到了n元平均。

A special case is that two distinct arguments, which belong respectively to two subevents, compete for the same θ-role. What should be done then is to make one of the arguments implicit so that every θ-role is assigned to one argument only. When the verb means bodily emission or congestion, its highly inferable argument as the entity in motion is often made implicit too, leaving an empty space for the θ-role.

比较特殊的情况是分属于两个事件的不同论元争夺同一语义角色，这时须隐藏其中一个论元，使每一个语义角色分且仅分给一个论元；而当动词意为"体物外排"或"外物内纳"时，作为运动实体的论元因为不言自明也常被隐去，留下一个语义角色空位。

This paper focuses on:(1) the mapping of different metadata sets, finding the relation of two metadata if their different owner_sets are described with RDF Schema;(2) the mapping of one metadata query statement onto several other metadata query statements in order to make several data providers work synchronously;(3) introducing the principle of Web services architecture, discussing why it is the best mode to integrate different systems.

The economic incomes per cruise of two specimen boats owners were permitted to be traced during two periods, May-June and September-December in 2003. The average income of fishing cruise which did not encounter dolphins was $NT 7327 dollars (SD=643 n=29 trips). The average income of fishing cruise which have encountered dolphins but no interruptions was $NT 7901 dollars (SD=1581 n=13 trips). The average income of fishing cruise which depredated by dolphins was NT 3137 dollars (SD=419 n=6 trips). The daily average income was $NT 6959 (SD=4211 n=48) per day.
