查询词典 nauplius

Dominant species were comprised of mainly micro- and meso-zooplankton species and planktonic larvae of benthos such as Parvocalanus crassirostris, Cirripedia nauplius, Oithona attenuata, Acrocalanus gibber, Nauplius, Bivalvia veliger, Copepodite, Oithona simplex and so on.

优势种主要是中小型种类和底栖动物的幼虫，如强额孔雀哲水蚤、蔓足类无节幼虫、细长腹剑水蚤、驼背隆哲水蚤、无节幼虫、双壳类面盘幼虫、桡足幼体、简长腹剑水蚤等。

L , Tuandao (293.95 ind./L), Huangdao (283.7 ind./L) and Nautical School (107.23 ind./L).5 At the Nautical School Sampling Station (24 hour monitoring station), the highest average density of microzooplankton was recorded at sunset (154.91 ind./L), successively, at sunrise (146.63 ind./L) and noon (93.09 ind./L), the lowest was at midnight (77.31 ind./L).6 Protozoa and copepod nauplius were the most dominant groups , comprising more than 90% of the total abundance of microzooplankton.7 In comparison with other gulf waters in the world, densities of microzooplankton and loricate ciliates in Jiaozhou Bay were at intermediate level.

在航校昼夜监测站，小型浮游动物的平均丰度以傍晚最高，其次是黎明和正午，午夜时密度最低，分别为154.91个／升、146.63个／升、93.09个／升和77.31个／升。6、胶州湾小型浮游动物以原生动物和无节幼体为主，两者共占小型浮游动物总数的90％以上。7、与世界其它海湾水域相比，胶州湾小型浮游动物的总平均丰度和砂壳纤毛虫的丰度，处丁中等水乎。

The nauplius eye was investigated by microscopy and transmission electron microscope.

从显微和超微水平研究了中国对虾幼虫眼的发育。

By TEM, every nauplius eye is composed of lens, retina cells and pigment cells.

电镜下，每个眼单位由晶体细胞、网膜细胞和色素细胞组成。

When adult, the nauplius eye is composed of three parts at least.

发育成熟的幼虫眼至少由3个眼单位组成。

The result shows: The nauplius eye appears at the nauplius in membrane stage.

结果表明，幼虫眼在膜内无节幼体期已具备。

PCR and electron microscope were used to detect the virus in the ovaries,eggs atdifferent development stages,and naupliuses of infected broodstocks of P.chinensis.Thevirus was not found in eggs just spawned or not,but in the connective tissue of ovary.Thedetected results of nauplius were positive,and virus-like organisms were found to invadethe epidermis tissue of nauplius.The virus was not detected in the yolk as well as inner andouter membrane of egg.

本文利用PCR及电镜技术，对中国对虾染病亲虾的卵巢和各期卵及其刚孵化出的无节幼体进行了病毒检测，染病亲虾刚产的卵及未产出的卵均没有发现病毒存在，在卵巢的结缔组织中检测到病毒存在，刚孵化出的无节幼体PCR检测结果呈阳性，电镜下观测到有病毒样颗粒侵染无节幼体的上层表皮组织。

Fc-vasa mRNAs were detected by RT-PCR in early developmental stages from 2-cells embry to intramembranous nauplius, and not in any stages after nauplius. Based on above results, it is postulated that Fc-vasa is required for germ cell determination and formation of F. chinensis as a maternal component.

但表达量逐渐降低，自出膜后的无节幼体开始检测不到表达信号，根据以上结果推测，Fc-vasa mRNA可能作为母源生殖质成分参与中国明对虾生殖细胞的决定和形成。

Mab 2A3 against all haemocytes and Mab 1H11 specific to cytoplasmic granules in granular haemocytes were generated and employed to study the ontogenesis of haemocytes by IFAT in Chinese shrimp embryos of blastula, gastrula, limb bud stage, embryonic-nauplius and nauplius I stages.

1利用杂交瘤技术，论文制备了特异性识别中国对虾所有三类血细胞的单抗2A3和特异性识别中国对虾大颗粒血细胞中细胞质颗粒的单抗1H11。

With Mab 2A3, the first positive cells were detected at the limb bud stage of the embryos. Distinguishable positive haemocytes with a diameter of about 7μm appeared in embryonic-nauplius. At the following nauplius I stage, configuration of haemocytes became more integrated and clear. Their diameters were almost similar to those of haemocytes from adult shrimp. With Mab 1H11, the first positive granular haemocytes were identified at the stage of embryonic-nauplius which existed in clusters with positive punctate fluorescence of granules distributed around the periphery of granular haemocytes.

通过对包括囊胚期、原肠胚期、肢芽期、膜内无节幼体期和无节幼体Ⅰ期在内的中国对虾胚胎的间接免疫荧光检测，最早在肢芽期胚胎中检测到2A3阳性信号；在膜内无节幼体期，2A3阳性血细胞平均直径约7μm，聚集成簇；在无节幼体Ⅰ期，血细胞形态更加完整清晰，平均直径已与成体对虾血细胞相似。1H11阳性大颗粒细胞最早在膜内无节幼体期胚胎中出现，这些细胞同样成簇存在，在其细胞质外围可见点状荧光。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
