造船周期 meaning in Chinese

shipbuilding period

The data needed by the calculation system is provided by the design section . the study can improve the efficiency of frame bending for shipyards
船体型材加工逆直线方法及划线机研究可以提高造船工业中的型材弯曲加工效率，缩短造船周期，减轻劳动强度。
The prediction of the noise level in the cabin and work space at design stage is aiming to make effective measurement to control the noise level in advance to meet the regulations and ship owner ' s needs , which can avoid incidental expanses in the remediation and modification , so as to shorten the period and cut the construction cost of ship . in order to predict the noise levels in the ship superstructure cabin , the two methods are discussed in this paper , such as the grey prediction method and the acoustics analysis in fem method
如果能在船舶设计开发的初期就能对其舱室、工作空间的噪声值进行预测，对不满足相关规范或船东要求的部位提前采取有力的措施，不仅能有效的达到减少舱室噪声的目的，还能避免在船舶建造完成后因采取补救和改动措施而造成的巨额开销，从而缩短了造船周期，降低了造船成本。
