Mm. 7.5.3 Requirements for quality of weld joint's surface: a No crack, not fusional, bubble, slag, splash; b Surface of seam of pipeline with design temperature lower than -29℃, stainless steel pipeline and alloy steel pipeline with trend of harden quenching shall be free from undercut.

The surface shall be smooth 7.5.3 焊接接头表面的质量应符合下列要求： 28 SH 3501-2002 a 不得有裂纹，未熔合，气孔，夹渣，飞溅存在； b设计温度低于-29℃的管道，不锈钢和淬硬倾向较大的合金钢管道焊缝表面，不得有咬边现象；其他材质管道焊缝咬边深度不应大于 0.5mm，连续咬边长度不应大于 100mm，且焊缝两侧咬边总长不大于该焊缝全长的 10%； c 焊缝表面不得低于管道表面，焊缝余高Δh 应符合下列要求： 1 100%射线检测焊接接头，其Δh≤1+0.2b1，且不大于 2mm； 2 其余的焊接接头，Δh≤1+0.2b1，且不大于 3mm。

Card sets of connections, in China only developed in recent years, it's connecting and sealing principle is that when the nut tightened up, the card sets under pressure to edge into the tube outer wall of the Department of bite, card sets and outside the cone with the joint under pressure All cone density in vivo, which can reliably prevent the leakage.

卡套连接，在我国近年才发展起来，它的连接和密封原理是，当旋紧螺母时，卡套受到压力，使其刃部咬入管子外壁，卡套外锥面又在压力下与接头体内锥面密合，因而能够可靠地防止泄漏。

If there are frequent bite on the lips may cause anterior crossbite combined, prominent lower jaw forward.

The common observation that dogs and cats nibble on grass, presumably when ill, strengthens our belief in the healing power of grasses.

共同的看法，狗和貓輕咬草地，大概患病時，加強了我們的信念，癒合權力草。

IM: To investigate the effects of occlusal surface anatomy on stress distribution around apex in mandible.

目的：探明正常牙合与重度磨耗牙合两种不同牙合型时各牙根尖应力分布的特征，以期揭示牙的解剖形态及牙尖高度的改变对咬合力传导的影响规律。

Firstly, based on foreign engineering experience and result of research, combining with test trial road, soil condition is the most important factor to rubllization, elsewhere DBL has little influence.

通过现场勘察，分析了碎石化后混凝土板块的分层情况及各层的受力特点，提出了咬合嵌挤理论，解释了板块破碎后强度形成机理。

The results indicated that treatment with Gothic arch tracing method was very effective for the patients with occlu- sal deasease.

结论哥特式弓形描记法是恢复正常颌位水平关系、治疗下颌偏位引起咬合障碍所致症状的有效方法。

Methods Gothic arch tracing method was applied to20patients that included10patients of face unbalance,6patients of TMJDS,4patients of myofasical pain to confirm mandible's relations.

对20例患者，其中面部失衡患者10例，颞下颌关节紊。。。目的改善因为下颌偏位引起咬合障碍的总义齿患者，恢复其正常的生理功能。方法对20例患者，其中面部失衡患者10例，颞下颌关节紊乱综合征患者6例，肌筋膜疼痛4例。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
