    摘要: Improved method for manufacturing spherical cryogenic liquid holding tanks as well as the tanks produced thereby, wherein at least the major hemispherical portions of such tanks are formed from curvilinear elongated quadralateral plate members which in the case of a given tank each have substantially the same arcuate minor axis dimensional width when measured at the midpoint of the arcuate major axis but varying lengths. These plate members of varying lengths are initially selectively arranged and secured to each other to form a series of substantially symmetrical and uniformly dimensioned, individual, triangular spherical tank sectors or modules. These spherical sectors or modules are subsequently secured to each other such that the longest plate member of a given sector is located adjacent or in close proximity to the tank's equator while the midpoints of the major axes of the various plate members in such a spherical sector are located in substantially parallel relationship to each other and the tank's equator in the finished tank structure.
