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。

Energy transfer between these two centers would result in appearance of long lasting phosphorescence.

而整个过程主要涉及两个中心，即发光中心和陷阱中心，它们之间的能量传递是产生余辉发光的主要原因。

For disaster behavioral psychology shows that the public at the scene of the fire escape when the performance of the "Biological phototaxis" and "sheep mentality" is the main reason for the failure to escape; the fire evacuation routes designed to maintain the smooth flow of the premise, the solution to the fire lighting and visual guidance problem, we solved the major problem of fire escape.

为灾行为心理学表明，公众在火灾现场逃生时所表现的＂生物趋光性"和"从众心理是导致逃生失败的主要原因；在消防疏散通道设计合理、保持畅通的前提下，解决了火灾中的照明及视觉引导问题，就解决了火灾逃生的主要问题。

Results: The major findings are:(1) the public held strong belief in the preventability of AIDS/STDs and considered prevention was of greater importance than biomedical interventions,(2) of the possible prevention strategies proposed by the research participants, personal behavior control was deemed as the most ef fective; meanwhile a sense of powerlessness was expressed while mentioning the government's responsibility for keeping the quality of blood supply and managing the potential dangers posed by other people's behavior,(3) condoms were well accepted as an effective tool for AIDS/STDs prevention but were used mostly for the purposes of contraception than HIV/STDs prevention, and (4) people were unwilling to use condom mainly due to sensational and psychological discomforts.

结果：(1)民众多认为爱滋病的「可预防性」极高，且视预防比高科技的解决方式重要；(2)个人行为的控制乃最受民众重视的防治途径；但对政府的血液安全管制及他人行为所可能造成的危害较感无力；(3)民众对保险套之使用持相当肯定之态度，不过曾使用者绝大多数以避孕而非以预防性病为主要目的，男女性在这方面的行为差异极大；(4)身体及心理上的不适与不悦被一般民众指出是保险套使用率低的主要原因，(5)教育程度对民众在预防的认知及信念扮演极重要的角色。
