PNA hybridizes with DNA or RNA by means of Waston Cricks base pairs complementary with high stability, affinity and selectivity. PNA not only regulates DNA replication, but also adjusts DNA transcription and translation. Many applications have been explored as a new kind of molecular biological tool and a gene targeting strategy.

肽核酸是一类人工合成的核酸类似物，PNA与核酸链以 Waston- Crick碱基配对方式稳定互补结合，具有高度的亲合性、稳定性、特异性特征，PNA能调节基因的表达作用，包括调节基因的复制、转录、翻译过程，因此 PNA有着广泛的分子生物学效应，显示出作为基因调节药物的应用潜力

Paired t-test analysis was performed on the thresholds of SVR and PTA at each frequency (0.5, 1, 2 and 4kHz), and analysis of variance was performed on the difference between the pure tone audiometry threshold and the evoked potential threshold among different frequency.

对听力正常的46名志愿者，分别对双耳进行0.125~8kHz频率范围内的PTA阈值及0.5~4kHz频率范围内的SVR反应阈测试，通过配对t检验比较0.5、1，2、4kHz频率范围的SVR反应阈与PTA阈值的差异，并运用方差分析比较不同频率间的SVR反应阈与PTA阈值差值的差异。

Convincing evidence indicates that matching for HLA class I cross-reactive groups rather than conventional HLA antigen matching may result in improved renal graft survival. T and B lymphocyte crossmatch before transplantation was done to determine whether there is any human leukocyte antigen antibodies to the graft.

等待肾脏移植的病人数量有限，然而要找到HLA配对很好的机率真的很低，后来有新的策略，将大量的HLA等位基因缩减为一些决定常见的HLA抗原的少量联系紧密的HLA等位基因组，称为交叉反应组。

The purpose of this study was to investigate what was happening in a prematurely terminated supervision case with the focus of observation on the interactions between the supervisor and the supervisee. We analyzed four sessions of one supervisory dyad in order to draw a comprehensive picture of the supervisory process. Our analysis showed that the dropout of this supervisee was caused by a series of mild and severe conflict events.

本研究的目的乃在对一个提早终止的督导关系进行分析，分析的焦点在整个督导历程与双方的互动关系，由於这个督导配对共维持四次督导，因此本研究针对这四次督导历程进行密集分析，以掌握与了解督导双方的互动情形、督导关系中发生的事件，并从中找出可能造成督导关系提前结束的互动形态。

Just in time of that paragraph of time is the period that Chinese Dui matchs to be broken through to do one's best of male double 、 afresh, just turned the Shang Xianhu that holds the post of male double coach Fu Haifeng admeasure the Cai 赟 with the particularly exquisite technology before the net, two Ge actor is short of the player with apparent Dian to be combined together, the each other that formed harmony fills, just also had today China male double achievement.

那段时间正好是中国队重新配对男双、力求突破的时期，刚转任男双教练的汤仙虎把付海峰配给了网前技术特别细腻的蔡赟，两个优缺点很明显的选手组合在一起，形成了和谐的互补，也才有了今天中国男双的成就。

Perfusion in the right parietal lobe in group2 was significantly lower than in group1 (P.01).（2）Average perfusions were higher in the right temporal and parietal lobes than in the left in all 3 groups.（3）Gray matter volumes were significantly smaller in group3 than in group2 (P.05); total cerebral spinal fluidsvolumes were significantly larger in group3 than in group1 and group2（P.05）; right hippocampus volumes were significantly smaller in group3 than in group1 （P.05）. Conclusions Age-related change of cerebral blood perfusions in the healthy elderly over 65 years is characterized with hypoperfusion in the right parietal.

结果（1）经方差分析，第2组和第3组脑组织几乎所有部位的灌注均低于第1组，其中第2组右顶叶灌注的放射性计数比值为0.87±0.18，低于第1组（RAR=0.98±0.17；P.01）；（2）经配对t检验，除第2组的双侧顶叶外，3组颞叶和顶叶的灌注均为右侧高于左侧（P.01和0.05）；（3）经方差分析，第3组的灰质体积占颅内容积的百分比［（47.59±1.26）%］小于第2组［（49.43±1.30）%］，总脑脊液体积占颅内容积的百分比［（14.61±3.16）%］大于第1组［（12.41±0.73）%］和第2组［（11.94±1.27）%］，右侧海马体积［（2.04±0.23）cm3］小于第1组［（2.27±0.20）cm3］，P均。05。

Using Basket warrants transaction data on TSEC from September 4, 1997 to June 25, 2001, the combination of four volatility models classical history volatility,Parkinson's(1980 high, low history volatility model,Garman and Klass's(1980) high, low, opening, closing history volatility model,Trippi's(1977) equal weights implied volatility model with two pricing models Black and Sholes's(1973 option pricing model, henceforth BS pricing model,Chen and Cheng's(2000) basket option pricing model, henceforth CC pricing model are discussed on valuation performance to obtain superior basket warrant pricing model.

摘要本文利用1997年9月4日至2001年6月26日间在台湾证券交易所发行且已到期的组合型认购权证，使用四种波动性估计模型历史波动性模型，Parkinson(1980的最高，最低价历史波动性模型，Garman and Klass(1980)的最高，最低，开盘，收盘价历史波动性模型，Trippi(1977)的等加权平均隐含波动性模型与Black and Sholes(1973)选择权评价模式，陈松男与郑翔尹(2000)的组合型权证评价模式配对成八种评价模式，并比较其评价绩效，冀期能得到一较佳的组合型认购权证评价模式。
