Any of numerous plants of the genus Oxalis, having often cloverlike compound leaves with three leaflets and variously colored flowers that are usually clustered in umbels.

酢浆草属任一种酢浆草属的植物，经常有混合的三叶状的复叶，附有三片小叶，有各色的花通常集聚在伞状花序上

Water stress is one of the most important abiological stress to maize seedling .In this study, we arm to identify the sensitive stage of maize seedling to water stress and select the material which tolerance to flooding. And we use waterlogging tolerance index to identify the sensitive stage of maize seedling. we have studied 20 inbred lines of maize which seedlings under water stress in three stage. The result show that the three leave stage is the most obvious stage to flood stress. In addition, we have analyzed ten of the inbred lines to re-act the waterlogging tolerance index. The result show good re-action. And the result also show that waterlogging tolerance index is a credible index to select waterlogging tolerance materials in seedling.

涝渍是玉米苗期主要的非生物逆境胁迫之一；本试验通过对20份玉米自交系进行苗期的淹水对照试验，采用了三个处理时期，并利用耐渍系数作为指标进行敏感时期的鉴定，结果表明三叶一心期是淹水的相对最佳时期；同时利用其中10份自交系对耐渍系数的重演性进行了分析，结果表明其重演性很好；同时结果还表明耐渍系数是耐渍性鉴定的一个可靠指标。

本论文由三部分组成：第一部分为天然表面活性植物无患子的应用研究；第二部分为无患子的化学成分研究；第三部分为天然表面活性植物木槿叶的应用研究。1。

To study on the turbulent flow in a centrifugal pump with vaned diffusers, based on CFD method, three-dimensional turbulent flow field in suction chamber, impeller and diversion shell was calculated at three different operating conditions, and the velocity and pressure distribution in diversion shell were obtained.

以带有空间导叶的离心泵为研究对象，通过CFD方法，在三种工况下，对包括吸入室、叶轮和导流壳在内的全三维湍流场进行数值计算，获得了导流壳内的速度分布和压力分布。

Organically reared cows, which eat high levels of fresh grass, clover pasture and grass clover silage, produced milk which is on average 50% higher in vitamin E, 75% higher in beta carotene (which our bodies convert to Vitamin A) and two to three times higher in the antioxidants lutein and zeaxanthine than non-organic milk.

有机饲养的奶牛，吃的高水平的新鲜草，苜蓿牧草和青贮草三叶草，生产牛奶，这是对平均高50 ％，在维生素E， 75 ％为高，在β胡萝卜素（即我们的身体转换成维生素A ）和两高出三倍，在抗氧化剂叶黄素和zeaxanthine比非有机牛奶。

In this paper, we present a wave theory based rendering technique: light wave field rendering, by combining wave graphics, Fourier optics, computational holography and the existed image based rendering techniques. In light wave field rendering, a 3D wave field is represented by one or more wavefronts which are stored as 2D arrays of complex numbers.

本文结合波动图形学、计算全息学和傅立叶光学等研究领域的相关技术，将波动的概念引入光场绘制过程，根据定态光波场的解析特性，使用平面或封闭曲面波前上的二维复振幅分布，来表示无源空间中三维的光波场，提出了一种基于光波场的绘制技术，用于三维物体的视点无关绘制和立体真实再现。

And this stems from a more bona fide Irish tale that tells how Patrick used the three-leafed shamrock to explain the Trinity. He used it in his sermons to represent how the Father, the Son, and the Holy Spirit could all exist as separate elements of the same entity.

这传统来自一个古爱尔兰传说：帕特里克利用三叶草解释三位一体的神如何以圣父、圣子和圣灵的三个不同位格存在。

Its diffuser ,composed of three spheres joined together simulating a clover ,manufactured from UV stabilised opal polyethylene and is secured to the corresponding high-shine polished stainless steel columns .

它的扩散，对三个领域结合在一起组成模拟了三叶草，紫外线稳定蛋白石聚乙烯制造，并获得相应的高光泽抛光不锈钢柱。
