Analyzes the performane of plane concave resonators with internal thermal lenses and gives out stability and unstability regions in terms of dioptric. Based on the stable and unstable resonators′ characteristics,a detailed analysis for output power of cw plane concave Nd:YAG laser is presented.

光泵Nd：YAG激光器的热效应会在YAG棒中引起轴向热伸长和径向折射率梯度，从而产生激光介质的热透镜效应，有关内含热透镜的谐振腔的研究已有许多报道［1～2］，但基本上都是研究谐振腔的热稳性，对输出功率特性的研究报道很少。

In this thesis, a totally new type of chiral heteropolyanion, [Sb_5_(10)Mo_5O_(26)]~(7-), has been isolated as racemic compound 1. The racemate was further resolved into enantiomerically pure crystals L-2 and R-2 by addition of organic units.

本文我们得到了一个由新的手性多阴离子[Sb_5_(10)Mo_5O_(26)]~(7-)构筑的外消旋体1，通过向外消旋体1的溶液中加入有机基团，实现了对外消旋体1的拆分得到了纯旋光活性化合物2，即L-2和R-2。

Teddy award-winning lesbian film director Zero Chou, scholar and activist Josephine Ho, disabled queer radio presenter Vincent and Hong Kong Rainbow founder Kenneth Cheung are among the people who also appeared before the crowd this year to share with passers-by and the queer audience some of the experience and work they have done in their respective fields.

We developed the spatial information, which included DTM, topography, slope, aspect, altitude, temperature, precipitation, light soil types, soil texture, administrative zoning, forestry zoing, stream transportation network. The colored aerophotos were scanned and corrected to be orthogonal images. Then, land cover were interpretated and land-use mapping. Ecological site quality of Chamaecyparis formosensis were evaluated for productivity. Habitat suitability index of warbers and guid were evaluated for biodiversity of landscape. The restoration strategies of collapsed area after Chi-Chi earthquake were developed by land evaluation.

本研究以中兴大学实验惠荪场为，进空间资讯之建构，其内容包括DTM、地形、坡、坡向、海拔高、气温、雨、湿、光、土壤种、土壤质地、政区划、业区划、溪、交通线等分布，并用彩色航空摄影照片扫描化且校正成正射投影之影像、地覆判释、郁闭、分高分布图与土地用型图制作；由空间资库进分层取样设计，以供有效之地面调查，而进生产的生态地位评估、地景多样性的野生动物栖息地适宜评估、以及集集921 地震后崩塌地分析、评估与回策之拟定应用，结果显示空间资讯在生态系经营的政策性与策性规划应用上，相当有效。

Results CT displayed the lesions located in the bladder neck and triangle area in 7 cases, in the right anterior wall in 1 cases, involve the entire bladder wall in 2 cases. Eight cases showed the local thickening or nodular or flat dune-like shape thickening of the bladder wall, the size of the lesions were 1.0cm × 0.8cm ~ 4.3cm × 5.9cm, two cases showed the diffuse thickening of the bladder wall. Cystal low density were demonstrated in 2 lesions.The bladder exine were smooth in 9 cases.

结果 10例CG中CT表现为膀胱颈部和三角区7例，右前壁1例，累及整个膀胱壁2例。8例CT平扫表现为膀胱壁局限性增厚或呈结节状、扁丘状突向膀胱腔内的软组织密度影，大小1.0cm×0.8cm～4.3cm×5.9cm，2例膀胱壁弥漫性增厚，边缘光整。2例病灶内可见囊性低密度区。9例膀胱外壁光滑。

The characters of powder are connected with the inside structure and synthesize-technics of materials. In this paper, we want to search a optimize technics of materials synthesizing, and prepare a kind of nanosize powder which shape like ball and have good dispersed character. At the same time, we want to obtain a bridge structure of Zn-O-Tb through dopping of Tb, which can achieve efficient energy transfer from ZnO hosts to excited states of dopants, The doped powder can eradiate blazing green light because of efficient emission buildup from dopants and ZnO hosts, and the powder can emission a pure light. And we want to research the structure in doped ZnO for the further research of low-tension fluorescence of ZnO.

粉体的这些特性无不与其内部结构特征和制备工艺有关，基于这些，本文的实验目的是希望能寻找一种合适的制备方法和优化工艺，制备分散性好的球形纳米颗粒，希望改善其表面形貌，同时，通过铽掺杂，希望得到一种Zn-O-Tb桥联结构，实现氧化锌基体向铽发光中心的能量传递，希望铽中心特征发射和氧化锌绿光发射能有效叠加增强，改善粉体的单色性，制备出好的复合粉体，分析清楚其结构，从而为后续低压荧光特性研究作准备。

Cerebrovascular diseases can lead to hemiplegia, hemiparaesthesia and hemianopia. However, patients with poor eyesight resulting from bilateral cerebral infarction are rare.

脑血管病常引起偏身运动功能障碍、偏身感觉障碍和同向性偏盲，但双侧脑梗死引起双眼视力下降至仅存光感的患者较为少见。

We come to you in the Light, divine emissaries from the Creative Source.

我们在光中向你们走来，来自创造性源泉神性使者。

Being South Asian, they would have grown up watching the painted lady that is Mumbai in the movies: a city of flashy cars and flashier women. A pleasure-loving city, a sensual city. Everything that preachers of every religion thunder against. It is, as a monk of the pacifist Jain religion explained to me,"paap-ni-bhoomi": the sinful land.

作为南亚人，他们在成长过程中一定是看到了电影中的孟买，一个流光异彩，食色性也的城市，这个城市的一切都是每一个宗教的传教士们竭力反对的，正如一个和平主义的Jain教徒向我解释的，这是一片罪恶的土地。

Through the Indus leaves little cracks on the path to a full exposure of the golden sunshine, a small roadside wildflowers also insisted on a bright modesty exposed to the smiling faces of visitors, a section of the beautiful water bridge section, a piece serene natural environment, Daihatsu makes poetic:"The mountains Koetsu bird nature Tan Ying empty people's hearts."

透过梧桐树叶的点点缝隙，小径上照射到了满满的金灿灿的阳光，路旁的小野花还坚持着向游人露出明媚娇羞的笑脸，一段段小桥流水的美好，一片片安详自然的环境，让人诗性大发：&山光悦鸟性，潭影空人心。&

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.
