I'D LIKE TO SPEAK ABOUT MY NSD EMERITUS OFFSPRING NANCY SULLIVAN.

所以我想要谈谈我的荣誉延伸首席南西。苏丽文。

The Assimilation Capacity Model suggests that the endothermy evolution in birds and mammals is driven by two factors:①a selection for intense post-hatching parent behavior, particularly feeding offspring, and ②the high cost of maintaining the increased capacity of the visceral organs necessary to support high rates of total daily energy expenditures.

同化能力模型认为，在鸟类和兽类中内温性进化由以下两个因素所推动：①子代出生后双亲行为加强；②为支持每日总体能量高速消耗所需，动物内脏器官能力增强而导致的较高维持消耗。

Researches on drosophila, mice and yeast also suggested that epistasis between nuclear and mitochondria affected significantly the phenotype of offspring.

细胞质效应在动植物中广泛存在，在模式生物果蝇、小鼠和酵母上的研究表明，细胞质与细胞核间的上位性互作效应对后代有明显的影响。

The "stemma equimultiple random select cross method" and "random mating method" were used to propagate offspring population of Langshan chicken. For each population, the pedigree of individuals were ascended up to 5 generations. Then, their generation increment of inbreeding coefficient was caculated using the regression slope rate.

以狼山鸡为素材，利用"家系等量随机选配法"和"随机交配法"2种保种方法进行继代繁殖鸡群，每个保种群每个世代的鸡只均逐只编制往上追溯5代的系谱图，利用回归斜率分析方法计算世代增量。

Some sperm with damaged DNA may escape from the sperm surveillance mechanism and transmit the damage to the offspring.So research on the damage to sperm DNA has become one of the hot spots in reproductive medicine.

替代组蛋白成为精核蛋白的鱼精蛋白和大量的二硫键使精子染色体高度压缩，这种特化的结构可以保护精子DNA免受伤害，因此成熟精子对各种致病因素有较强的抵抗力。

Objective To study the influence of intrauterine hypoxia to offspring rat Ethology change and nerve cells in brain hippocampus degeneration and apoptosis.

目的研究宫内缺氧(intrauterine hypoxia ，IH)对子代成鼠行为学改变及神经细胞变性、调亡的影响。

In the nineteenth century, the most widely credited example was that of lord morton's mare, reported by the distinguished surgeon sir everard home, and cited by charles darwin.[4] lord morton bred a white mare with a wild quagga stallion,[5] and when he later bred the same mare with a white stallion, the offspring strangely had stripes in the legs, like the quagga.

在19世纪时期，被引用最多的例子来自lord morton的母马，是被外科医生everard所发现的，后来又被达尔文引证。lord morton把一匹白色母马和一匹种斑马交配，而后他又将同样一匹母马与一匹白色种马交配，它们的后代奇怪地在四条腿上带有条纹，就象那匹斑马。

Although august weismann had expressed doubts about the theory earlier, it did not fall out of scientific favor until the 1890s, when a series of experiments by james cossar ewart in scotland and other researchers in germany and brazil failed to find any evidence of the phenomenon. the result obtained by morton could probably be caused by the display in the offspring of the recessive genes inherited by the morton's mare from her parents/grandparents.

虽然august weismann早先对这个理论表示怀疑，但直到19世纪90年代，这理论仍然获得科学上的支持，直到 james cossar ewart in scotland 及其他一系列研究者在德国和巴西所做的一系列实验都未发现有关现象的证据。morton所观察到的现象可以被解释为后代从它的父母/祖父母身上继承了隐性基因，并表现出性状。

ugust Weismann对理论表示怀疑(也就是你回应提到马交配的实验，在本段的上半部有提及我就不引用了)但这理论始终得到学界支持，直到James Cossar Ewart在苏格兰，德国，巴西所做的系列实验都无法发现有关现象的根据；Morton观察到的，可以说是马遗传了亲代或祖父母的隐性基因，并表现出性状也就是最初实验马交配发表先父遗传的人

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
