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。

To study the bioactive components from water soluble extract of the Chinese eaglewood, various column chromatography of Chinese eaglewood led to the isolation of ten compounds. Their structures were elucidated as 2,3-bis(3-hydroxyphenyl)- propan-1-ol (1), [(2R,3R)-3-(4-amino-3,5-dimethoxyphenyl)oxiran-2-yl]methanol (2), 8-chloro-4'- methoxy-5,6,7,3'-tetrahydroxy-2-(2-phenethyl)-5,6,7,8-tetrahydrochromone (3), 4'-methoxy-5,6,7,3'-tetrahydroxy-2--5,6,7,8-tetrahydrochromone (4), the isomer of 4 (5), 4'-methoxy-5,6,7,8-tetrahydroxy-2-(3'-hydroxyphenethyl)-5,6,7,8- tetrahydrochromenone (6), 4'-methoxyisoagarotetrol (7), 6-hydroxy-2-(2-hydroxy-2- phenethyl)-chromone (8), 6-hydroxy-2-(2-phenethyl)-chromone (9), 6-hydroxy-2-(4'- hydroxy-2-phenethyl)-chromone (10), and Guaiacylacetone (11) by means of spectral analysis and comparison with references.

为了进一步发现沉香中具有生理活性的化学成分，本文对国产沉香的水溶性成分进行了研究，从中分离得到11个化合物，通过红外、紫外、质谱、核磁共振(1H-NMR， 13C-NMR， COSY， HSQC， HMBC， ROESY)波谱解析，分别鉴定为：2，3-二(3-羟基苯基)-丙-1-醇(1)，[(2R，3R)-3-(4-氨基-3，5-二甲氧苯基)-2-氧化烯基]甲醇(2)，8-氯-4'-甲氧基-5，6，7，3'-四羟基-2-(2-苯乙基)-5，6，7，8-四氢色原酮(3)，4'-甲氧基-5，6，7，3'-四羟基-2-(2-苯乙基)-5，6，7，8-四氢色原酮(4)，化合物3的差向异构体(5)，4'-甲氧基-5，6，7，8-四羟基-2-(3'-羟基-2-苯乙基)-5，6，7，8-四氢色原酮(6)，4'-甲氧基异沉香四醇(7)，6-羟基-2-(2-羟基-2-苯乙基)色原酮(8)，6-羟基-2-(2-苯乙基)色原酮(9)，6-羟基-2-(4'-羟基-2-苯乙基)色原酮(10)和Guaiacylacetone (11)。

What all manifestations of economism have as a fundamental characteristic is tailing the masses, instead of acting as a vanguard to lead the masses—learning from them, yes, but leading while learning—raising their sights to the possibility and necessity of revolution and working and struggling with them to win them to take up the revolutionary and communist standpoint and fight for its emancipating goals.

经济主义的基本特征表现为&跟随民众&，而不是争做先锋以便领导他们——向民众学习，但在学习中加以领导，使他们的眼光得到提高进而认识到革命的可能性和必需性，与他们一起工作、抗争，争取他们信仰革命和坚持共产主义立场，为实现无产阶级解放目标而斗争。

The surgery of female stress urinary incontinence has more ways,but it is essentially around two main themes:First,extense urethra,narrow urethra cavity diameter,increase urethral wall tension; Second,improve the bladder neck location,restore bladder urethra horn,recover the pressure transfer to urethra side when abdominal pressure increases,thus increase the urethral atresia pressure and length of the urethra,reach the aim to control incontinence.

女性压力性尿失禁手术治疗的方法较多，但本质上主要围绕两个主题进行：一是延长尿道，缩小尿道腔径，增加尿道壁张力；二是提高膀胱颈位置，恢复膀胱尿道后角，恢复增加腹压时压力向尿道侧的传递，从而增加尿道闭锁压及机能尿道长度，以达控制尿失禁的目的。

I see this unfortunate youth, hit the ancient grave to be evil I see in his cranial nerve to corrode by the ancient grave one kind of filtrable bacteria So that courses an originally lively optimistic excellent youth way of the suicide!

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。
