The highest seajiao xiao Suona flute sound, long strokesliu cun ; Suona treble flute called material, under about a foot; Alto flute solo show called Luo,er cun rod about a foot; Suona Tenor II called the first mixed, under foot by one inch in length; Suona bass flute called big stuffy, under one foot three-inch to one foot longwu cun .

最高音唢呐叫小海笛，杆长约六寸；高音唢呐叫材笛，杆长约一尺；中音唢呐叫罗戏笛，杆长约一尺二寸；次中音唢呐叫二混头，杆长约一尺一寸；低音唢呐叫大闷笛，杆长一尺三寸至一尺五寸。

This new scheme suggests that a shear and/or bending deflection would be allowed to take place freely in the specific part of the anchor rod which lies between the structure and the rock mass.

此方案在结构与岩体间保持一段可以自由剪切和弯曲的锚杆段，该锚杆段的长度称为自由长度。通过对闸墙受渗透压力、闸墙自重和温度等荷载的分析，发现锚杆自由长度对锚杆轴力的影响较小，而对锚杆剪力的影响很大。

结果 1、CON组与NIC组CD11b阳性小胶质细胞胞体小，呈杆状，突起细长，染成浅棕色：LPS组小鼠脑内CD11b阳性小胶质细胞胞体增大，呈圆形，突起粗而短，染成棕褐色；NIC+LPS组少量CD11b阳性小胶质细胞胞体增大，圆形，突起变粗变短，染成深棕色，多数呈杆状，突起少、细长，染成浅棕色。

They are the strengthening-toughening of 40SiMnCrNiMoA by the critical normalizing, the fine macrostructure and property matching between the all drill rod parts, the low tendency of decarburizing and delete the weak inner hole surface owe to the drill-hole and hot-rolled with core process of rolling steel.

本文研究表明，40SiMnCrNiMoA钢亚温正火强韧化特性、亚温正火使钎杆整体性能良好地匹配、较小的脱碳倾向和钻孔法消除钎杆内孔粗糙和脱碳表面是钻孔法并整体780℃亚温正火+钎柄淬火和低温回火的H22-40SiMnCrNiMoA锥体连接小钎杆延寿的主要原因。

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。

To address this situation, I believe that the operation could be improved on are: the installation and adjustment of measuring, the first sub-scale do to adjust the nominal cylinder liner size, and then dial indicator card installed and well well inserted under the initial installation of the traffic card directly into the cylinder table by measuring the smallest cylinder liner wear, the cylinder table adjust the volume of the extended length of rod inserted, so that the volume of the dial indicator cylinder table has small hands around 1.5-2.0 preloading cell volume and cylinder volume table mother under lock locking plug, the final table and then measured the volume of cylinder rod and rod card inserted at the anvil micrometer measuring bar between the seat and the large dial and adjust the dial indicator to zero.

针对这种情况，笔者认为，操作上可改进为：安装和调整量具时，先将干分尺调整到气缸套的公称尺寸，再将卡装好百分表和初步安装好插杆的量缸表直接卡入所测气缸套磨损最小处，调整量缸表插杆的伸出长度，使量缸表的百分表小表针有1.5-2.0格左右的预压量并将量缸表的插杆锁母锁紧，最后再将量缸表的测杆和插杆卡在千分尺的砧座和测杆之间并将百分表的大表盘调整到零。

Engine cylinder liner of the general process of measurement are: cylinder liner according to the nominal size measuring selection, that is, sub-thousand-foot-cylinder form and quantity (including the volume of cylinder rod inserted table); installation and adjustment of measuring, that is first to adjust micrometer cylinder liner the nominal size, and then loaded card good indicator of the volume of cylinder form measuring bar and the bar card inserted in the anvil micrometer measuring bar between the seat and adjust the volume of cylinder form of extended length of rod inserted, when the dial indicator of the 1.5-2.0 cells have small hands around the amount of pre-press under lock-lock female plug, and a large dial indicator to zero adjust

发动机气缸套测量的一般过程是：根据气缸套的公称尺寸选择量具，即千分尺和量缸表；安装和调整量具，即先将千分尺调整到气缸套的公称尺寸，再将卡装好百分表的量缸表的测杆和插杆卡在千分尺的砧座和测杆之间，调整量缸表插杆的伸出长度，当百分表的小表针有1.5-2.0格左右的预压量时锁紧插杆锁母，并将百分表的大表盘调整到零

The first direct measurement with micrometer piston skirt and the outside diameter Do micrometer stop screw to the locking plate position, and then dial indicator card installed and well well inserted under the initial installation of the amount of cards, directly into the cylinder corresponding cylinder kit, adjust the volume of the cylinder rod out in table inserted length, so that small hands dial indicator cell has about 1 volume of pre-press and lock locking rod inserted mother, at the same time, large dial indicator dial to adjust zero, the last cylinder to adjust the volume of good form under test card inserted rods and do at Anvil micrometer and measured the rod between the big hands dial indicator at this time than the "zero" high value is the piston and cylinder liner with the space.

3先直接用千分尺测量活塞裙部的外径并将干分尺止动螺钉扳转到锁紧位置，再将卡装好百分表和初步安装好插杆的量缸表直接卡入对应气缸套内，调整量缸表插杆的伸出长度，使百分表的小表针有1格左右的预压量并锁紧插杆锁母，同时将百分表的大表盘调整到零，最后将调整好的量缸表的测杆和插杆卡在干分尺的砧座和测杆之间，此时百分表大表针比&零&高的数值即为活塞和气缸套的配合间隙。
