To ensure close adhibition of connecting board, screwing should start from center to outside, that is, screwing from enlarged center to skirting area. To avoid coating's influence on tensile force, screwing work should be finished on one day. And to decrease prestress' difference of high-tension bolt, bolt screwing runs in two steps: primary screwing and final screwing. For large-scale joint with great amount of bolts demands a second screwing.

为使被连接板叠密贴紧，应从螺栓群中央顺序向外施拧，即从节点中刚变大的中央按顺序向下受约束的边缘施拧，为防止高强度螺栓连接副的表面处理涂层发生变化影响拉力，应在当天终拧完毕，为减少先拧后拧的高强度螺栓预拉力的差别，其拧紧必须分为初拧和终拧两步进行，对于大型节点，螺栓数量较多，则需要增加一道复拧工序。

The top of neural tube forms basic encenphalic shape,namely endbrain, interbrain, midbrain and afterbrain. The abnormal closure of neural tube will result in neural tube detects. Encephalocoele is a common congenital malformation whose mechanism was no known. NO participates in the physiologic process of brain.

胚胎脑发育的早期阶段主要是神经板隆起、弯曲、闭合形成神经管，神经管的头部从前向后依次发育形成脑的基本组织形态，即端脑、间脑、中脑、后脑，在神经管闭合过程中出现异常就会导致NTD。

The research contents mainly include: First, the influence of foundation constraint condition to the temperature stress is analyzed, the temperature stress formula of ultra-long concrete anchor plate is deduced, then the influence of length to structure crack can be gotten from the formula. Second, a breathing method is set up to solve the problem of temperature stress in ultra-long concrete constructions. By setting the sliding floor, a breathing system is built up and the temperature stress reduced distinctly. Third, the effect of prestress technique in the control of temperature stress is analyzed, it is simulated and calculated through FEA to get the right way to apply the prestress. Forth, the delay of temperature field and unsteady conduction is considered, the temperature field of ultra-long concrete structure with later poured band is simulated, then temperature stress distribution after casting the concrete is calculated, finally the effect of later poured band to temperature stress of ultra-long structure is analyzed.
