本研究中，作者共整理报告 32 科约 300 种台湾产的陆生软体动物，其中许多种类为近年新发现之新物种，显示台湾的陆生软体动物多样性仍有广大探索空间。

On the other hand, alien species, which may be harmfulto crops, is a vital issue concerning pest control in agriculture. In addition, it still remains further study whether the competitive exclusion effect caused by invasive land mollusks endangers the endemic land molluscan diversity of Taiwan.

某些特定种类属於入侵之外来种，对农作物会造成相当危害，在农业病虫害防治方面亦应留意；入侵外来种陆生软体动物对原生种的竞争排斥效应，对台湾陆生软体动物多样性的威胁亦属未来研究重点之一。

The mutual coupling effects between the BS diversity antennas are analyzed using the Method of Moments in this thesis.

本文采用矩量法分析了基站分集天线间的相互耦合影响。

A 25μL solution with genomic DNA 25ng/μL, MgCl_2 1.5mmol/L, dNTPs 0.1mmol/L, random primer 0.1μmol/L, 1U TaqDNA polymerase would be optimum for the amplification reaction.

按照优化的RAPD条件进行实验，重现性良好。2种裸腹在盐胁迫条件下的种群遗传多样性分析表明，同种裸腹不同生存盐度之间的种群遗传相似度较高，分别为0.9134和0.9038；而多刺裸腹和蒙古裸腹两个种间的遗传相似度相对较低，约为0.5～0.6。

It played an important role in the phylogeny of monocotyledon and the plants with reticulate vein. The haplotypes of trnL-F and atpB-rbcL noncoding regions of cpDNA were analysed to infer phylogeography and the history of speciation, and the possible refugia of Croomia. ISSR markers were used to study the level and patterns of genetic diversity of Croomia.

本文通过cpDNA非编码区trnL-F和atpB-rbcL序列研究了Croomia的分子亲缘地理学，推测了可能的冰期避难所和物种形成、演化的历史；同时通过ISSR分子标记研究了Croomia的遗传多样性分布格局及其与地理格局间的关系，并在此基础上提出了相应的保护策略。
