At last, natural frequencies of practical pre-stressed composite space truss are tested with pulsatory method on construction site and its damping ratio is calculated, which gives another important data for engineering design. In addition, through the model experiment of pre-stressed rectangular square pyramid composite space truss, the correctness of characteristics of internal force and the feasibility of tension recovery method are proved.

最后，在工程施工现场用脉动法测试自振频率，并借助于振动衰减曲线和半功率点法计算出预应力组合网架——钢与混凝土的混合结构体系——的阻尼比，此又为工程设计提供了一理论依据；另外，通过正放四角锥预应力组合网架的模型试验，验证了结构内力分布特点的正确性以及张力松弛法的可行性。

A flying sunny smile rayed in his loose features.

The microstructure and thermal physical properties of the surface reactional layer determine the range of strength improvement.Stress relaxation was benifical for strength,but the oxidation-induced bubbles and crack weaken the specimens.

热处理引起的应力松弛也有利于材料强度的提高，但氧化过程中产生的表面气孔及冷却过程中产生的表面微裂纹会引起材料强度的下降。

rutaecarpine pharmacological effects and its related mechanism: rutaecarpine the heart positive inotropic, positive changes in the role and the heart protective effect, which with its promotion of calcitonin gene-related peptide release; rutaecarpine alkali have vasodilative and hypotensive effect, its mechanism mainly related to endothelial cells Ca2 +-NO-cGMP pathways and calcitonin gene-related peptide release; rutaecarpine to relax the anal sphincter, gastrointestinal motility inhibition of stress ulcer and ulcerative colitis have therapeutic effect; rutaecarpine on cerebral ischemia-reperfusion injury has a protective effect, which instead of increasing the concentration of calcitonin gene-related peptide-related; rutaecarpine inhibits platelet aggregation and arterial thrombosis; In addition, rutaecarpine Alkali also anti-inflammatory and analgesic, anti-tumor and other pharmacological effects.

综述了吴茱萸次碱的药理作用及其相关机制：吴茱萸次碱对心脏有正性肌力、正性变时作用和心脏保护作用，这与其促进降钙素基因相关肽释放有关；吴茱萸次碱有扩血管和降压作用，其机制主要涉及内皮细胞Ca2+-NO-cGMP途径和降钙素基因相关肽的释放；吴茱萸次碱能松弛肛门内括约肌，抑制胃肠运动，对应激性溃疡和溃疡性结肠炎也有治疗作用；吴茱萸次碱对脑缺血再灌注损伤有保护作用，这与其增加降钙素基因相关肽浓度有关；吴茱萸次碱能抑制血小板聚集和动脉血栓形成；此外，吴茱萸次碱还有抗炎镇痛、抗肿瘤等药理作用。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
