混流式转轮可靠的疲劳寿命评估包含两部分：第一，用来描述电站如何运行的载荷配置。第二，对于所有基本的运行工况，制造商必须在设计阶段就预测和考虑由于静态和动态载荷引起的结构部件应力。因此，水电部件的动载荷条件和对疲劳寿命产生的影响都是科学研究的组成部分。在过去的几年里，重点研究了偏离设计的运行工况和过渡工况。基于应变片在真机转轮和模型上试验测量的经验，以及先进的数值仿真计算，极大加深了对动载荷的理解。从测量和仿真的相互关系出发，为了提高疲劳寿命，开发了一套标准的流程。本文对近期在提高混流式转轮的效率和鲁棒性方面的研究成果进行了总结和归纳。

介绍了一个后向叶轮压缩机在16000r/min 转速情况下进入旋转失速状态而引起叶片失效的例子。为了搞清失效的原因,用复制叶轮在同样的压缩机上,对不稳定流动作了系统研究。在目前的情况下,发现双旋转失速团激振的二倍频正好落在共振范围内,而强使叶片失效。还发现危险激振的另一个来源是多气团旋转失速的激振。现在已开始研究多失速团现象的影响因素,这些研究表明,增大扩压器进口半径比和减小扩压器叶片进口角可以减轻这种危险激振的危害性。

Based on the mechanism of chromatographic retention (the relationship between the retention of solute and the mobile phase conditions) and method of resolution map, several methods of optimizing multi-segment linear gradient elution conditions were proposed according to the different separation requirements of various samples. These methods were verified using literature data. Moreover, the advantages and disadvantages of these methods were compared. It was proved that the third method is a fast optimization method which is capable of separating all the components with relatively high resolution.

Photoconvertible fluorescent proteins such as Kaede are routinely used for tracking proteins, organelles, and whole cells. Kaede was the first identified photoconvertible fluorescent protein and has since become the most commonly used photoconvertible fluorescent protein in vertebrates. Kaede can be irreversibly converted from a green to a red fluo- rescent form upon uV/blue light irradiation and fluorescence of each form can be isolated separately by appropriate filter sets. Spectral properties of the Kaede forms allow F6rster resonance energy transfer （FRET） from the green form as donor to the red form as acceptor. As a sample containing oligomerized Kaede-containing proteins is exposed to uV or blue light, FRET first increases as green Kaede is converted to red and then decreases as the green donor becomes depleted. Thus, FRET information is potentially obtained from a number of independent measurements taken as photoconversion proceeds. We demonstrate here the application of this approach to detect homo-aggregation and conformational dynamics of plant pro- tein constructs. Structural alterations of 2-cys peroxiredoxin-Kaede were successfully detected depending on the redox state in living plant cells. Photoconversion was performed gradually and donor emission, acceptor emission, and FRET-derived sensitized acceptor emission were measured at each step of conversion. Since photoconvertible proteins have not been rou- tinely used in plants, two plasmids have been designed to facilitate plant applications. The plasmids allow either transient expression of Kaede-containing protein constructs in plant cells or Gateway cloning and stable transformation of plants.
