Let G be a finite group, and S a subset of G not containing theidentity element 1. The Cayley digraph Cay on G with respect to S is definedas a directed graph with vertex set G and edge set {|g∈G, s∈S}. IfS~(-1)=S, then Cay is undirected and in this case, we view two directededges and as an undirected edge {u, v}. Obviously, the right regularrepresentation R of G, the acting group of G by right multiplication, is asubgroup of the full automorphism group AutCay(G, S of Cay.

给定有限群G，设S是G的不含单位元1的子集，群G关于子集S的Cayley有向图Cay是一个以G顶点集合，而以｛|g∈G，s∈S｝为边集合的有向图，特别地，若S~(-1)=S，则X=Cay是无向的，此时我们把一条无向边｛u，v｝等同于两条有向边和，易见，群G的右正则表示R，即G在G上的右乘作用，为图Cay的全自同构群AutCay

A graph G is acyclically L-list colorable if for a given list assignment L there is an acyclic coloringπof the vertices such thatπ∈L.

若G有一个正常的无圈染色π，使得对每一个顶点v∈V，都有π∈L，则称G是无圈L-可染的或者称π是G的一个无圈L-染色。

The major findings include:(1) By using fuel as the base indicator of relative efficiency, we found the following input factors' distribution inefficiency for domestic airlines: The distribution inefficiency of labor and capital input factors differs from airline to airline, and is becoming more severe with time; the distribution inefficiency of other factors does not differ very much among airlines but varies with time. It is inefficient from 1989 to 1995 but becomes more efficient during 1996 to 1997;(2) Airline companies have higher economies of density before 1996, but tend to show a constant return to density in 1997 when considering allocative distortions. The technical efficiency of input factors as a whole has declined after the open-air policy;(3) The costs of airlines are increasing significantly due to their distribution inefficiencies;(4) The instrument variable generated through a quasi price function does not have significant influence on cost; this may imply that airline companies in this time period did not exhibit the phenomena of high-quality high-price.

其主要结论如下：(1)藉由相对燃油分配效率探讨各投入要素之分配扭曲情形发现：劳动和因定投入要素之分配无效率因公司别而有所不同，且随时间而严重，唯民国86年稍有改善；其他要素之分配无效率则较不因公司别而有所不同，但亦随时间发生变化，初期为无效率，在民国85、86年则较具效率；(2)若考虑分配扭曲情形下，国内航空业在民国85年之前具有较高之密度经济，民国86年则趋向固定密度报酬；此整体投入要素之技术效率而官，在天空开放政策后其技术效率随时间变化而下降，但就燃油投入要素平均技术进步率而言，则其技术效率逐年增加且幅度明显；(3)航空公司因分配无效率所造成成本增加的情形相当明显；(4)准价格工具变数对成本之影响并不明显，此可能反映在此期间国内航空公司似乎并未趋向於高品质高价格之现象。

C Where the assured has no insurable interest throughout the currency of the risk, the premium is returnable, proviede that this rule does not apply to a policy effected by way of gaming or wagering; Where the assured has a defeasible interest which is terminated during the currency of the risk, the premium is not returnable; Where the assured has over-insured under an unvalued policy, a proportionate part of the premium is returnable; Subject to the foregoing provisions, where the assured has over-insured by double insurance, a proportionate part of the several premiums is returnable; Provided that, if the policy are effected at different times, and any earlier policy has at any time borne the entire risk, or if a claim has been paid on the policy in respect of the full sum insured thereby, no premium is returnable in respect of that policy, and when the double insurance is effected knowingly by the assured no premium is returnable.

c 如果在整个风险存在期间，被保险人无保险利益，保险费可予退回，但这一规则对赌博性保险单不适用。如果被保险人的可撤销的利益于风险存在期间终止，则保险费不能退回。如被保险人不定值保险单中超额保险，保险费得按比例退还一部分。除前述条款另有规定外，若被保险人经重复保险而超额保险，几笔保险费按比例退还。但是，如果几份保险单在不同时间开始生效，任何较早订立的保险单已在任何时间承保整个保险，或保险单已就全部保险金额支付赔偿，该保险单项下的保险费不能退回；若被保险人在明知的情况下订立重复保险，保险费不予退还。

Generally, instrumental rumination helped to reduce negative mood, emotional-focused rumination worsened negative mood, and meaning-searching rumination increased the duration of negative mood. Moreover, in the period of severely and long-term negative mood status, instrumental rumination seemed to maintain the duration of positive mood, emotional-focused rumination still worsened negative mood, and meaning-searching rumination seemed to prolong the duration of negative mood. Besides, in the period of negative mood episode, instrumental ruminative had no effect on mood fluctuation, emotional-focused rumination deteriorated and extended negative mood, and meaning-searching rumination had harmful effect on the negative mood but still had borderline effect on the positive mood.

整体平均来说，功用性反刍有助於负向情绪的缓解、情绪焦点反刍会增强负向情绪感受、意义寻找反刍则是增加负向情绪维持的时间；若当天处在长期又严重情绪不佳日子中时，功用性反刍似有维持正向情绪的效用、情绪焦点反刍则是恶化当天的负向情绪强度、意义寻找反刍则有延长当天负向情绪时间的趋势；若连续处在长期且严重情绪不佳的日子中，功用性反刍对情绪变化并无影响、情绪焦点反刍则是延长且恶化此时期的负向情绪状态、而意义寻找反刍不但会影响负向情绪的状态，似也会有助於此时期的正向情绪状态。

Degree sum conditions of IM-extendable graphs are researched. The main results are as follows:(1) Let G be a graph with 2n vertices. If for each pair of nonadjacent vertices u and v in G,, then G is IM-extendable.(2) Let G be a claw-free graph with 2n vertices. If for each pair of nonadjacent vertices u and v in G,d+d≥2n+3, then G is IM-extendable.

研究导出匹配可扩图的度和条件，主要结果如下：(1)若图G有2n个顶点，且对于G中每一对不相邻的顶点u和v，，则G是导出匹配可扩的；(2)若G是一个有2n个顶点的无爪图，且对于G中每一对不相邻的顶点u和v，d+d≥2n+3，则G是导出匹配可扩的。

Whereas osteoporosis is unassociated with bone pain, osteomalacia has been associated with isolated or generalized bone pain.39,40 The cause is thought to be hydration of the demineralized gelatin matrix beneath the periosteum; the hydrated matrix pushes outward on the periosteum, causing throbbing, aching pain.7 Osteomalacia can often be diagnosed by using moderate force to press the thumb on the sternum or anterior tibia, which can elicit bone pain.7,40 One study showed that 93% of persons 10 to 65 years of age who were admitted to a hospital emergency department with muscle aches and bone pain and who had a wide ariety of diagnoses, including fibromyalgia, chronic fatigue syndrome, and depression, were deficient in itamin D.41

然而，骨质疏松症与骨痛无关联，而软骨病则与局部性或全身性骨痛有关。其原因被认为是骨膜下已去矿质化的胶原基质上发生的水合反应，水合的胶原基质在骨膜上向外扩张，引起阵痛。软骨病可通过以拇指适度挤压胸骨和胫骨前方以引起骨痛感。一项研究显示10岁到65岁中有93%的人向医院急诊室承认有肌肉疼痛和骨痛症状，他们还有一些其他症状包括纤维肌痛、慢性疲劳综合征、抑郁等，该研究显示他们都缺乏维生素D。本人已认领该文第9、10两部分，48小时后若未提交译文，请其他战友自由认领。本人已认领该文11、12部分编译，48小时后若未提交译文，请其他战友自由认领。本人认领第十三部分，48小时内交稿请战友纠错！

若黄版印得太浅，印不入人物的肤色不有有朝气感，衡宇象古庙不同陈腐，使人难以剥夺；若黄版印得太不浓，复制不入的画背丰润无暗不浓，色调方向蓝紫，也不丑陋。

The data were analyzed in terms of the procedures, which were explicated by The Grounded Theory in the first stage and The Phenomenology in the second stage. The findings of this study were as follow:(1) The model of drug using was dynamic cycles, including initial drug using, continued using, addiction, reintegration, relapse, re-continued using and re-addiction to drugs. But not all cases entered into this cycle.(2) Some drug abusers may stop using drug because of some reasons, but it was hard to confirm that they didn't reenter this cycle again.

结果发现：进入用药行为的循环历程模式，吸毒者呈现出一个初尝、持续使用、成瘾、重整、再度用药、持续使用、成瘾的循环动态之过程，不过并非每个个案均完全进行循环，在每一个阶段中个案有可能随时因某些因素而中止，但中止并不代表个案即真正戒除毒品，视个案反思、自觉能力的强弱，有无进入深度的痛改而采取行动达到真正的戒除，若无则可能在某些条件的促进下又再度进入吸毒的循环中。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
