The petal of Gli CMS crimples.The stamen turns into featheriness, the form of the petal , silk form or degradates. Without anther structure, the carpel, it is protruding that the outer edge grows tumour form.The growing style of stamen and pistil is the adhesion type or the scattered type. The shape of pistil is straight or hooked. The opening style of flower is full-nfolded,half-closed or full-closed.

The above results showed that physiological AAI pacing maintained a normal EAS and VAS, and improved or enhanced VSS; while nonphysiological VVI pacing and physiological DDD pacing induced the decrease in VSS due to an abnormal EAS and VAS. Furthermore, with increasing the pacing rate, VSS was markedly decreased.The quantitative comparison of parameters of left ventricular systolic function obtained by computerized ERNA showed that AAI pacing induced the significant increases in ventricular ejection rate and stroke volume with concomitant shortening of ejection time.

应用计算机-ERNA相位分析技术，对13例生理性AAI、13例非生理性VVI及6例生理性DDD患者，分别进行等相位电影，相位图，相位直方图和VSS参数的静动态观察和定量比较，结果显示：AAI起搏可维持正常EAS和VAS，心室相位均匀一致，并且VSS参数-相角程，半高宽和峰相位标准差均较起搏前分别降低，提示起搏后VSS有所改善或增强。

There are 18 species of Paphiopedilum in China. Most of them grow in limestone regions and are epiphytic or terrestrial. There are two types of leaves mottled leaves and green leaves. They distribute in subtropics of China. Five species of subgenus Brachypelalum are the most primitive grou p of Paphiopedilum in China and four of them distributed in the limeston e re gions of Eastsouth Yunnan. Most species of Paphiopedilum distribute in this area,too.

国产兜兰野生种共有18种，主要分布于热带过渡地区，主产西南各省区；大多数种类生长于石灰岩山地，多为半附生兰，呈丛生生长，另一部分生长于酸性砂岩面的腐叶土上，多为地生兰，呈单株生长或分蘖状散生；大部分兜兰分布于较高海拔地区；国产兜兰属中最原始的短瓣亚属绝大部分种类仅分布在滇东南地区与贵州、广西连成一片的岩溶地貌的石灰岩地区，而兜兰属中较进化的兜兰亚属大部分种类在本区皆有分布。

Results showed that total vegetation coverage, herbaceous coverage, and species richness were all decreased, and perennial species gradually gave place to psammophyte annuals, shrubs, and semi-shrubs from gentle slope hilly ridge, through saline bottomland and fixed and semi-fixed dune, and to shifting and semi-shifting dune.

结果表明，从缓坡丘陵梁地，经盐化丘间低地、固定半固定沙地到流动半流动沙丘，植被总盖度、草本植物盖度、物种丰富度均呈下降趋势；植被组成中多年生草本植物逐渐减少，一年生草本植物及沙生灌木、半灌木逐渐增加。
