You can find out it is the major temporary work, such as formwork, rebar jig, equipment etc. during the FPLM construction, in which the cost of the inner mould and outer form of box girder, the steel form of pier and pierhead of substructure, the rebar jig as well as the launching equipments are quite high. The quantity of those equipments was always depended on experience in the pass time. Therefore the more of the form quantity is used the higher of direct costs would be spent. On the other hand it would be reduced the capacity of production if the equipments are insufficient.

在全跨预铸工法中所使用的生产设备仔细观察可发现，预铸工法中假设工程(如模版、钢筋加工架以及施工机具等)所占比例相当高，其中有箱型梁的内模与外模床、下构的柱钢模、帽梁钢模、钢筋加工架、吊装机具等所占的成本相当高，以往设备数量多寡均以经验来取决，因此假如模版数量过多直接成本随之提升，反观模版资源数量不足时又会造成生产力降低情况发生。

After introducing 56Nb steel, in order to meet performance requirement of 56Nb steel fish plate on the railroad rail, the production technique of 56Nb steel fish plate has been adopted under the factory equipment conditions: 450 kg steel ingot is prepared by melting in 8 t arc furnace and casting at 1 570-1 580℃ which is heated to 1 250-1 270 ℃, trimmed to 185 mm×195 mm bloom after rolling by 600 series 2-stand rolling mill; then rolled 15 times by 600 series 2-stand rolling mill when steel ing

介绍了56Nb钢后，根据铁道接头夹板的性能要求并结合厂方的设备状况制定了56Nb钢鱼尾板材料的生产工艺：用8 t电弧炉冶炼，于1 570～1 580℃下铸成450 kg钢锭；将钢锭加热到1 250～1 270℃，经600系列2机架轧机5道次轧制后修整成185 mm×195 mm方坯；再将钢坯加热到1 050～1 150℃，由600系列轧机（2机架）共15道次轧制，用350系列（3机架）精轧机经3道次精轧成60 kg/m的鱼尾板材料，终轧温度约900℃。

Two hysteretic models suitable for damaged and undamaged fiber-reinforced prestressed wide-beam frames were proposed sequentially. The hysteretic models consisted of a skeleton curves which based on the concept of three stage polygonal line with soften region and some hysteretic rules.

When the temperature is increasing quickly,the steel work will be destroyed easily without the protection of fire-proofing,therefore, the designing aim of steel frame fire-resistance is:how to quantitatively confirm the protectional measure in fire resistance in order to let the time of the fire resistance in steel work be longer or at least equal wit.

因此 ，在钢结构抗火设计时必须考虑到：如何定量地确定防火保护措施，使得钢结构构件的耐火时间大于或等于规定的耐火极

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
