Because of the importance of the detection of R-wave position, this paper also proposed a filtering method for exercise ECG signal, which is based on Wavelet Transform and Stein's Unbiased Risk Estimate. Our experimental results demonstrate that the myoelectric disturbances and baseline drift in EECG signal can be removed efficiently, which affords the solid foundation for the further evaluation and study of people's sub-healthy state in various vocations.

此外，由于心音和心电的所有参数分析都是基于心电R波的正确定位后进行的，作者结合小波变化和似然无偏估计，提出了运动心电信号的伪差消除法，经过实验论证，本算法能有效消除运动心电信号中的基线飘移和肌电干扰，为进一步研究分析评估不同行业人群的亚健康状态提供了新途径。

The charts of velocity vector of flow field outside the tube under five conditions with amplitude 1.3 mm and frequency 5—25 Hz were obtained,and the cosine of average synergy angle of flow field outside the tube was calculated.

实验及模拟结果表明：振动能够显著增加管外近壁区的流体速度，能够在振动方向上的管壁两侧形成有效的冲刷，随着振动频率的升高其管外近壁区的平均速度近似呈线性增加，在共振点出现峰值；相同区域内振动工况的平均场协同角余弦值要明显大于无振动工况，但不同振动频率间的场协同角余弦值变化较小。

Pseudoverticillata, but there was no significant change in Celtis wightii. There was no significant change in leaf area specific hydraulic conductivity K(subscript l between the two seasons in all the three species, which may caused by the adjustment in hydraulic architecture through partial loss of leaves during the dry season. In the dry season, maximum carbon assimilate rate A(subscript max was significantly lower than that of the wet season in all the three species.

除油朴的枝条边材比导率K(下标 s在旱季和雨季没有显著性差异外，尖叶闭花木和轮叶戟的K在旱季都有显著的降低；而枝条的叶比导率K(下标 l三树种在两个季节间均无显著变化。K在旱季没有显著性降低，可能是常绿树种在旱季通过脱落部分叶片以调整其水力结构来保持较高的单位叶面积的水分供应。

Bronchiolitis obliterans is the most disturbing complication following lung transplantation. This study is to investigate whether prolonged ischemia would promote early establishment of BO Material and Methods Left lower lobectomy was performed from miniature swine. Lung fragments, each measured 1 cm3, contained terminal bronchioles were auto- or alloimplanted into the subcutaneous area around the nipples. These lung implants were removed on 7th; 14 th; 21 th; 28th and 56th days and were fixed for histological examination. Experimental group using the same procedures but the left lower lobe was washed with 4.degree.C Lactate ringer via interlobar artery before lobar bronchus was resected.

肺移植后的阻塞性细支气管炎是肺移植后最困扰的并发症，本研究的目的希望了解缺血时间的延长是否会促进阻塞性细支气管炎提早发生实验方法施行小猪的左下肺叶切除手术，将取下的肺切成含终末支气管1 公分立方的肺小块，以自体及异体异位肺移植模式，将植入小猪皮下的肺小块於植入后第7、14、21、28 及56 天取下，在病理下检示其病理变化，并利用原位灌留的方式将左下肺叶以4℃林格氏液灌洗后再摘除之，观察有无灌洗对於阻塞性细支气管炎生成的影响。

Conceptualizing Rural Development in the World Today Since the start of the Industrial Revolution and colonial times, agricultural change has been driven by the pull towards cities; the emergence of new livelihoods; and, in some cases, by famine, war and landlessness resulting from population growth, civil conflict, land consolidation by legal and illegal means; and, of course, by opening of agricultural lands in forests, wetlands or other natural areas.

全球农村发展的今天自从～之后产业革命的开始和殖民地居民乘，农业的变化已经被驱使被那向城市拉；新生计的出现；并且，在一些情形，藉着起因于人口生长、市民的冲突的饥荒、战争和无土地，土地合法和违法方法的巩固；并且，当然，藉着农业土地的打开在森林、洼地或其他的天然区域中。

Between 1936 and 1975, GEICO grew from a standing start to a 4% market share, becoming the country's fourth largest auto insurer. During most of this period, the company was superbly managed, achieving both excellent volume gains and high profits. It looked unstoppable. But after my friend and hero Lorimer Davidson retired as CEO in 1970, his successors soon made a huge mistake by underreserving for losses. This produced faulty cost information, which in turn produced inadequate pricing. By 1976, GEICO was on the brink of failure.

从1936到1975这40年间，GEICO从无到4%的市场占有率，成为全美第四大的汽车保险公司，大部份的时候，公司的经营相当上轨道，营收与获利同步成长，看起来势不可挡，但直到该公司总裁，同时也是我的好朋友Davidson在1970年宣布退休，情势随即起了变化，他的继任者犯下损失准备提拨不足的大错，此举大大扭曲了成本结构，进而导致不当的订价，1976年，GEICO已濒临倒闭。

Had rarely or never used protective;(11) MiceGrayAuto had realized the automatic processing of video data from the sexual preference observation system of rats, and MiceGrayManu had accomplished the analysis of images of sexual behaviors of rats;(12) Peripheral given of high dose androgen to female rats before its brain sexual differentiation had caused masculinization and defemininization in female rats, therefore led to homosexuality, and based on the results, we had established the female rat homosexual model;(13) Peripheral given of estrogen to male rats before its brain sexual differentiation had little effects on the sexual preference and sexual behavior of adult rats;(14) Peripheral given of estrogen antagonist to male rats before its brain sexual differentiation had markedly reduced masculine sexual behavior and interfered male sexual preference, but had no effect on feminine sexual behavior, and based on such results, we had established the male rat homosexual model, however the model have to be improved for better sensitivity;(15) The volume of sexually dimorphism nucleus of the preoptic area of the high dose androgen-treated female rats was significantly greater, while on the other hand the volume of AVPV of which was significantly lesser, than the female rat control.
