Its occurrence is due to puberty, the body secretion of sex hormone imbalance, facial oil gland secretion disorders, pore blocking, while the external intrusion caused by the bacteria, but also plenty of constipation caused by inhaled toxins can also cause Qing Chundou growth.

它的发生是由于青春期，性荷尔蒙分泌失调身体，面部油腺分泌失调，毛孔阻塞，而外部入侵的细菌引起的，但也因吸入大量有毒物质引起便秘，也可能造成清Chundou增长。

Intravoneous injection of 0.5mg/kgBW jingsongling cause the 60 minutesrelaxation of goat gastric motor.The effects of jingsongling on the gastric motor ofgoat is major of effects of α2 -adrenoceptor agonist,as well as that of α1 -adrenoceptor agonist,the effects of α1 -adrenoceptor agonist concentrate at thecardic and pylorus;the function of α2 -adrenoceptor exit widely at cardic,pylorus,rumen,reticulum,omasum and abomasum,the function at different part is not the same.The lowestdose of jingsonglinginhibiting the amplitude and frequency of the gastricmyoelectric is 0.01mg/kgBW;the influence of jingsonglingto the gastricmotility of goat is dose-dependent,and the amplitude regain after the frequency ofgastric myoelectriv wave.When the goat revived,the gastric motor function is notreach the level of the normal;the major reason ofjingsongling cause the goat gastricrelaxation is the amplitude renew slowly.The intravoneous injection ofjingsonglingfirst,after 5 minutes,intravoneous injection the antagonist,the effect of prazosin and idazoxan mixed is best,which can fast reversal of theinhibition of jingsongling on the gastric motor of goat,the effects of idazoxan isgood,and the prazosin block the effection of jingsongling is better than that ofxylazine,especially at cardia and pylorus.When intravoneous injection of0.5mg/kgBW idazoxan and/or prazosin only,the amplitude of gastric myoelectric ingoat increases at a certain degree,but the frequency is not changed.

静脉注射0.5mk/kgBW的静松灵引起山羊胃蠕动弛缓长达60分钟；静脉注射0.5mg/kgBW的静松灵对山羊胃蠕动机能的影响是以α2肾上腺素受体作用为主的，兼有α1肾上腺素受体的作用，而且静松灵的α1肾上腺素受体的作用主要集中在幽门和贲门；α2肾上腺素受体的作用广泛存在于贲门、瘤胃、网胃、瓣胃、皱胃和幽门中，不同部位间有功能上的差异；静注0.01mg/kgBW的静松灵是对山羊的贲门、瘤胃、网胃、瓣胃、皱胃和幽门的肌电波频率和振幅均产生影响的最低剂量；静注一定剂量的静松灵对山羊胃蠕动的抑制作用与剂量呈相关性；而且山羊胃肌电波振幅的恢复比肌电波频率的恢复慢；苏醒时山羊的胃蠕动机能尚未恢复到正常状态；静松灵引起山羊胃弛缓的主要原因是由于胃肌电波的振幅恢复慢；静注0.5mg/kgBW的静松灵，5分钟后静注0.5mg/kgBW的拮抗剂时，咪唑克生+哌唑嗪的作用最好，能迅速地逆转静松灵对山羊胃蠕动的抑制作用，咪唑克生也有很强的拮抗作用，而哌唑嗪对静松灵的拮抗效果好于对隆朋的拮抗；单独静注0.5mg/kgBW的咪唑克生和/或哌唑嗪时，山羊的瘤胃、网胃、瓣胃、皱胃、贲门和幽门的肌电波振幅有一定程度的增强，而肌电波频率未见变化。

Plant of the orchid family because commercial value is high and those who cause hill civilian and lover is excessive collect with manage, the one; that makes the main reason that orchid species is in severe danger on the other hand, because factitious development is a mountainous area, if give birth to the fell trees of selva to wait formerly, the destruction that causes zoology environment; is belonged to plus plant of the orchid family, planted distributinging belt is narrow, reach its oneself is progenitive and not easy, to living the environment asks to compare other plant slashing, make it becomes world biology to protect one of centers that organize an attention.

兰科植物由于商业价值高而引起山民和爱好者的过度采集与经营，成为兰花物种濒危的主要原因之一；另一方面，由于人为的开发山区，如原生热带雨林的砍伐等，引起生态环境的破坏；再加上兰科植物属、种的分布带狭窄，及其自身繁殖不易，对生存环境要求比其他植物苛刻，就使它成为世界生物保护组织注重的中心之一。

By means of the orthogonal expansion technique, the coupling system solutions are finally obtained. Then the dynamic model of saturated soil layer caused by pile longitudinal vibration is founded. Incorporated wave propagations into saturated soil layer, the characteristics of soil resistance factor and the mechanism of the radial damping are analyzed, as well as distributions of shear stress and pore pressure in saturated soil caused by pile vibration.

然后利用上述解析解分析了饱和土层复阻抗，并从饱和土波动理论出发，建立了桩纵向振动引起的饱和土层振动模式，剖析了辐射阻尼产生机理，研究了桩纵向振动引起的饱和土层中剪应力及孔隙水压力分布。

Remedial sex arouses the cure of the obstacle, still have no at present medication effectively, hormone replaces the fall with the estrogen clear standard that after treating pair of the turn of life, menopause or ovariotomy art, causes, dry, sexual intercourse has the atrophy of vaginal mucous membrane that cause, vagina to be helped certainly sorely.

这种变异不仅存在于表型不稳定的早代孤雌系中，而且还存在于表型稳定的高代系中，造成这种变异的原因可能是因为远缘种质的引入影响到遗传平衡进而引起染色体发生结构重排并引起染色质的变化，这种变化与玉米染色体组中非同源染色体间存在的同源片段和因此造成的减数分裂过程中非同源染色体配对有着直接的关系。

What we need to seriously take account in and receive with special attention is, however, the mindset of western people, thinking that the conflict between powers results from the transfer of power, since Thucydides, the great Grecian historian wrote in his masterpiece "History of the War of Peloponnese " in analyzing what made the war inevitable," it was because the strengthening Greece fueled the fears of Sparta."

然而，自从伟大的古希腊历史学家修昔底德在《伯罗奔尼撒战争史》一书中提出，使得伯罗奔尼撒战争不可避免的原因是因为"雅典权力的增强以及由此而引起的斯巴达的恐惧"以来，权力转移必然是引起大国冲突已经成为了西方人的思维定式，这一点却是值得我们高度重视和认真对待的。
