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。

Therefore liquid CO_2 avoids gas-solid multiphase flow, and supplies continuous low temperature gas for cryoprobe. Experimental results show that the 2-dimension temperature distribution for the first time, it includes:(1) The cooling velocity and freezing zone increases along the flux up at certain size of the cryoprobe in the same biological tissue.(2) As the diameter of cryoprobe increases, the temperature will descend faster, freezing zone will be broader obviously, and ice ball become larger. Until it arrives heat balance, the temperature keeps invariability.(3) Single freezing-thaw results in biggish mechanical injury already for loosen tissue such as pork liver; Successive freeze-thaw circle could quicken freezing and thaw velocity for compact tissue, and it has proved the more mechanical injury of successive freeze-thaw circle than the single freezing-thaw treatment.
文中首次对生物组织进行了二维温度场分布实验研究,得出:(1)当刀头大小一定,对同一组织冷冻时,流量越大,降温速度越快,降温影响区域越大;(2)随着冷刀直径的增加,降温速度随着增加;温度影响区域明显增大;冰球直径也随着增大,热量平衡后温度几乎不随时间变化;(3)对于结构疏松组织比如猪肺脏,单次冻融对组织已造成较大的机械破损;对于结构较致密组织,多次反复冻融可以使降温和复温速率增加,单次冻融的热应力造成的机械破损较小,多次冻融后造成的机械破损比单次冻融所造成的机械破损大;(4)直喷式刀头比导热式节能约15%。

Additionally, species with larger plasticity in biomass allocation and relative growth rate also showed higher seedling survival rate.7 All these suggested that higher light availability in grazed disturbed meadow community favor seedling recruitment for these familiar forbs component species, but bottom shade in fertilized meadow community restrain seedling recruitment for these species.
在变化的微生境下,具有较小生长可塑性的物种具有相对较大的幼苗存活率;而生物量、株高可塑性和平均可塑性较高的物种具有相对较大的幼苗越冬存活率;具有较大的生物量分配和相对生长率可塑性的物种幼苗具有相对较大的存活率。7放牧干扰下的高光照微生境有利于这些草甸常见组分种实生幼苗的更新补充,而施肥后草甸群落冠层底部的低光生境不利于这些物种的更新补充。
