This study mainly investigated the effect of maternal undernutrition during late pregnancy on the levels of hormones which take the somatotropic axis as the center in ewes, the expression of partil hormones'mRNA and the gene localization in tissue cells on the basis of animal nutrition, endocrine physiology and by modern molecular biology technique. The experiments explored the mechanism of restriction and compensatory in order to pave the way for applying compensatory growth for animal husbandry scientifically.

本研究依据内分泌生理学和动物营养学理论，应用现代分子生物学技术系统研究了限饲及补偿生长对母羊生长轴激素基因表达水平的影响以及部分激素在母羊组织细胞中基因表达定位规律，进一步探究了绵羊补偿生长与内分泌生长轴的关系，为更科学地将动物的补偿生长能力应用于畜牧业生产上奠定理论基础。

Patent, and then the blade-to-blade flow was computed by solving the two-dimensional steady Navier-Stokes equations, finally, overall performance and internal flowfield characterization were obtained and analyzed.2. As to radial matching between blade sections, preliminary investigations were developed from three aspects such as stall margin customizing technique, control technology of tip clearance flow, prediction model and control technology of corner separate.a On basis of reviewing on methods of achieving the goal of stall margin in design process of fan and axial-flow compressor, in conjunction of understandings on "Sweep/Dihedral", stall margin customizing technique was put forward; two-dimensional performance prediction method for stall margin customizing was developed, it can consider influences of radial stacking patterns of blade sections and axial distances between blade rows conveniently and rapidly.b A simple model for tip leakage mixing loss of unshrouded blades for compressible flow was presented.

二、叶片基元展向匹配方面，本研究从影响负荷最大化的叶身展向积迭注：原(来源：ABC论文35网www.abclunwen.com指掠弯是裕度定制的一部分，为方便论述，本文将此统一论述为裕度定制、叶尖间隙、叶片与端壁角区这三个最重要因素出发，探讨了各因素影响负荷最大化的机理，并由此给出了最大负荷设计过程中的技术措施和努力方向。1从掌控风扇/轴流压气机裕度方法回顾入手，探析了美国和俄罗斯裕度控制方法及相应特点，结合对&掠/弯&因素的认识提出了裕度定制技术：并开发了能够体现裕度定制思想的二维特性预估方法，可在二维层面下方便快捷地考虑以掠/弯为代表的叶片基元展向积迭以及叶片排间轴向间距带来的影响；2借鉴Denton关于不可压叶尖泄漏损失的理论分析，推导出适用于可压缩流动的叶尖泄漏掺混损失计算的基本关系式。
