Compared with 11 other isolates reported in GenBank, there was slightly variation in the nucleotide sequence of Omp25 gene of wapiti's isolate. The identities of nucleotide sequence and deduced amino acid sequences among 11 strains were 99.1%-99.4% could 99.2%-99.5% respectively.

与GenBank中已经登录的布氏杆菌其他11个分离株相比，马鹿布氏杆菌分离株Omp25基因变异较小，以散在的点突变为主，Omp25基因核苷酸和推导氨基酸序列的同源性分别为99.1%-99.4%和99.2%-99.5%之间。

The results showed the basic geographical variation patterns of Akebia trifoliate is mainly influenced first by the altitude then the latitude.

This study conducted a secondary data analysis based on the data from 1999 Survey of Health and Living Status of the Middle Aged and the Elderly in Taiwan, provided by the Bureau of Health Promotion, Department of Health, R.O.C.. The study subjects were elders over 65 years old, and the number of valid samples was 2890. The data were analyzed with descriptive statistics, one-way ANOVA, Chi-square test(X2), Independent-Samples t-test, point biserial correlation, the Pearson product-moment correlation, logistic regression analysis, multiple regression analysis and hierarchical regression analysis.

本研究乃是使用行政院卫生署国民健康局人口与健康调查研究中心执行之「台湾地区中老年身心社会生活状况长期追踪调查系列」1999年调查资料进行次级资料分析，研究样本为年满六十五岁以上之高龄者，有效样本数为2890人，针对所得的资料，以描述统计、单因子变异数分析、卡方检定、独立样本t检定、点二系列相关、皮尔森积差相关、逻辑回归、多元回归分析及阶层回归分析等统计方法进行分析。

Low genetic variation has probably resulted from the refugial nature of these populations since the last glaciation rather than from recurrent pollen dispersal between Chilanshan and Alishan populations of these 2 Chamaecyparis species. Two Hinfl restriction site differences were found in the trnV-trnM intergenic spacer between C. formosensis and C. taiwanensis. Fragment length difference as well as point mutations in the petG-trnP intergenic spacer between C. formosensis and C. taiwanensis were also found.

如此低的遗传变异可能是因为现今之红桧与台湾扁柏族群为冰河期存在之大族群的残留小族群，而未必是花粉散播所提供之基因交流极为频繁所造成。trnV-trnM基因间区间序列在红桧与台湾扁柏两者间有两个HinfI之酶切点之差异，在PetG-trnP基因间区间序列也发现台湾扁柏与红桧之间有限制酶片段长度及其他点突变。

Results: the location, shape and number of the sympathetic ganglia were quite variable, and there was 1 to 6 in number unilaterally. Lumbar sympathetic trunk divided into 2-3 branches at the distal part were found in 12 sides. Lumbar arteries were all located under the lumbar sympathetic trunk and the lumbar veins, consisting (68.42+4.35)% situated superficially to the trunk, mainly in L4 arid L5 veins. Genitofemoral nerve pierced psoas muscle at the level of L2-L4 or its intervertebral disc (0.83±0.48) cm away from the medial edge of psoas muscle.

结果：腰交感神经节数目及位置变异较大，每侧1~6个不等；腰交感干可分裂为2~5支，分裂处多在干的下端，本组共发现12侧发生分裂；腰动脉均位于神经干的深面，腰静脉位于腰交感干浅面者占(68.42±4.35)%，以腰4、5静脉多见；生殖股神经穿出腰大肌平面多数与第2~4腰椎或椎间盘对齐，穿出点距腰大肌内侧缘(0.81±0.48)cm。

The first, take the advantage of genetic algo- rithm ,using the stepping coding technique and adaptive muta- tion probability, it is to optimize the organization of networks and train the networks in the same tine.

首先利用全局搜索能力可靠的遗传算法，采用递阶编码方案和自适应变异概率，同时优化网络的权值和结构，在进化结束时，能够寻到全局最优点附近的点。

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。
