Reduction of ovule number as a tendency of speciation in the genus is substantiated by the occurrence of tri_ovulate cones coupled with comprehensive characters of the genus. The metamorphic patterns as well as the leaf nature of the outer envelope indicate that female cones of Ephedra are compound while the female reproductive units of the ovulate cone have been reduced from secondary reproductive shoots similar to those of cordaites by phylogenetic transformation, fusion and reduction. Each fertile bract together with its axillary female reproductive unit composed the Bract Scale and Seed Scale Complex of Ephedra .

These results suggest that the activate spleen-energy method can achieve appetitive purpose by not only affecting the gastrointestinal tract function in periphery, but also regulating the process of ingestion in brain. The basic research about ingestion indicate: one hand, after food enters the gastro-intestinal tract, the endocrine cell of the intestinal tract is activated and secrete many kinds of brains intestines peptide, the level of the brain intestines peptide in blood as the periphery signal spreads to the central nervous system regions that control digest and feeding behavior. On the other hand, it has been shown that dorsal parabranchial neurons, containing CCK-8S, extend fibers to the VMH and are involved in the inhibition of feeding .
关于摄食控制的基础研究表明,一方面食物进入胃肠道后,激活肠道的内分泌细胞,分泌多种脑肠肽如CCK-8S,这些脑肠肽在血中的水平作为外周信号可通过&肠—脑轴&传入中枢神经系统介导消化和摄食行为的部位,影响摄食中枢神经元的活动调节动物的摄食行为;另一方面中枢神经元可合成释放内源性的神经肽直接作用于摄食中枢神经元调节摄食,如中枢鳃旁体神经元的神经纤维就可延伸到达VMH,并且合成释放内源性的CCK-8S。

The calculation results shows that ,(1) when the rotor rotates at the working speed, a local regurgitant whirlpool that is rightabout to the rotor"s rotating direction appears in the classifying region, which makes the separated granules come back to the outside of the classification district and influences the classification efficiency of the turbine classifier;(2) in the condition of a low rotating speed of turbo rotor, ultrafine particles can follow the gas phase by and large, but when the rotating speed increases, a phenomenon of velocity slippage between two phases appears evidently;(3) A operating parameter, air flow rate is so important that can directly influence the stability of flow field in classifying chamber, the bigger the air flowrate is , the steadier the flow field is;(4) Compared with straight blades, the new shape of blades with backward crooked elbow are helpful to improve the stability of flow field and form whole stream easily, also beneficial to advance the classification accuracy and classification efficiency;(5) The motion trace of particles are very complicated when the turbo rotor rotates at a high speed, the constant bounce of the particles appear between the blades and the coarse particles are even bounce back from the inlet, only the finer can pass through the classification area from the oulet;(6) Along with the increase of the rotor"s rotating speed, radiah axial and tangential velocity all begain to fluctuate repetitively like sine-wave, the smaller the particles are, the more violently they fluctuates.
数值模拟结果表明,(1)在涡轮达到工作转速时,在分级区域形成了一个与涡轮旋转方向相反的局部回流涡,它使得分离出来的细粒重又被带回分级轮外边缘,从而严重影响分级机的分级效率;(2)粉尘粒子在涡轮低速运动情况下,基本上能跟随气体运动,但随着转速加大,两相之间出现了明显的速度滑移现象;(3)分级机工作时的风量也是一个比较重要的操作参数,它可以直接影响到分级机内腔流场的稳定性,风量越大,流场越稳定;(4)同直叶片形状相比较,带后弯导板的叶片,有利于改善流场的稳定性,流场容易形成整体流,对提高分级效率和分级精度都非常有利;(5)粒子轨迹线在涡轮转速较高时十分复杂,有的出现了反复的弹跳现象,大颗粒不能通过分级区域而从进口返流了,只有细小的颗粒才从出口处流出;(6)涡轮转速加大时,粒子的径向、轴向和切向速率出现了明显的类似于正弦波的脉动现象,颗粒越小,脉动程度越为剧烈。

This blowing fan has a hub connected to the rotating shaft of a motor and a number of blades mounted on the outside surface of the hub at fixed intervals to flow air in the centrifugal direction of the fan. Although this fan is produced in a shape of axial fan or diagonal fan by integrally forming the separate turbo blade on the tip or trailing edge of the rotor blade, the blowing noise can be reduced in addition to the increase in the entire wind quantity of the fan by embodying the optimum set angle of the turbo blade.
由连接在电动机的旋转轴上的轮毂和按一定间隔安装在上述轮毂外周面上的多片叶片构成、使空气向风扇的离心方向流动的送风风扇,虽然制作成将另外的涡轮叶片形成在旋转叶片的叶梢或后沿上而与其成为一体的轴流式风扇和斜流式风扇的形式,但通过实现上述涡轮叶片的最合适的设置角度,便使整个风扇的风量增大,同时减小送风噪音。

The results show that space finite analysis results are close to test ones, bottom chords suffer axial force and large in-plane bending, and the max stress is nearby each middle internode. The max stress of node crossbeams occurs in No.2 bottom flange, and that of internode crossbeams happens in ones lying in the middle of every internode. The concrete slab is in tension at the longitudinal direction, and also suffers bent at vertical loads. The degree of completely-composite model taking part in the combined actions is about 55%, while that of semi-composite model is 42%-43%. The combination of concrete slab and bottom chord increases the degree of floor system taking part in the combined actions, lightens the burden of bottom chord, and reduces out-of-plane bending of node crossbeams especially the ones near bridgehead. Stress and displacement of main truss can be evaluated by a equivalent plane rigid frame in preliminary design, and effective stiffness of bottom chords are composed of original ones and concrete slab, and the concentrated load from deck can be translated into uniform load.
研究结果表明:空间有限元分析结果与试验结果较吻合;下弦杆受到轴向拉力和较大的面内弯矩作用,各节间最大应力出现在节间中点附近;节点横梁最大应力发生在横梁2的下翼缘,节间横梁最大应力发生在位于端节间中部的小横梁上;混凝土板顺桥向整体受拉,并在竖向集中荷载作用下产生弯曲变形;全结合模型大部分节间内的桥面板参与主桁共同作用的程度为55%左右,半结合模型桥面板的参与程度为42%~43%;桥面板与下弦杆结合能够增加桥面板的参与程度,减轻下弦杆荷载,减少节点横梁尤其是靠近桥头横梁的面外弯曲;对桥梁进行初步设计时,主桁杆件的位移与内力可按照1个等效的平面刚架计算,下弦杆的等效刚度由原下弦杆截面和混凝土桥面板截面组合而成,桥面荷载可转化为均布荷载施加。
