线虫的

Ascaris lumbricoides (Linnaeus, 1758), the largest and most common of the intestinal helminthes of humans, has a world wide distribution. More than 1 billion of world population was reported to be infected. Ascaris suum (Goeze, 1782) is one of the most ordinary parasites which infects pigs and causes huge economic losses.

似蚓蛔线虫即俗称人蛔虫(Ascaris lumbricoides Linnaeus，1758)是世界上流行地域最广、感染人数最多的病原生物之一，严重危害人类健康；而猪蛔虫(Ascaris suum Goeze，1782)则是造成生猪感染的最常见寄生虫，可造成巨大的经济损失。

Comparison was made between the biological classification system for soil borne plant parasitic nematodes of the Tylenchina suborder and with a nonbiological one (Chinese Soil Taxonomy as an example) in biodiversity characteristics by calculating the power law distribution and Lognormal distribution of the two systems to analyze their similarities and differences.

本文通过计算两种系统分类的幂律和对数正态分布，对土壤植物寄生的线虫类分类体系和非生物系统分类的多样性特征进行了比较，进而分析它们之间的相似性和差异性。

In the early stage, the pathological change degree of parenchymatous cells upwards inoculated dot were more gently than those downwards. Then they went to be consistent later.

相同接种时间内，与接种点上下距离相同的松苗茎段细胞病变的趋势与线虫上下移动快慢差异是一致的。

Configuration characte of PCD appeared evidently in those cells. Especially for the quantity and speed of the PCD of cortex parenchymatous cells, they increased gradually together with the motion and diffusion of nematodes.

尤其是皮层薄壁细胞发生程序性死亡的数量和程度是随着时间的推移和线虫在松苗体内不断扩散分布而逐步显著增加的。

Comparing rDNA-ITS sequence analysis and AFLP analysis by UPGMA, the later is better for employing phylogenic relationship among Meloidogyne species.

比较rDNA-ITS序列分析和基因组DNA的AFLP分析，作者认为基因组DNA的AFLP分析方法，更能有效和客观地揭示根结线虫种间和种内的系统发育关系。

A: A single negative stool examination does not exclude a parasitic infection, since the sample may have been collected during the prepatent period (i.e., the time between infection and the production of detectable ova or larvae) or because the target organism may have been shed inconsistently or in low numbers, as is frequently the case with strongyloides larvae.

一次大便虫卵和寄生虫检查的阴性结果不能排除寄生虫感染，因为样本可能在潜伏期还暂时没有异常（如在感染和产生可以检测到的虫卵或幼体前）或者所关注的微生物已经排出，或者数量太少，如类圆线虫属。

Therefore, the production of SA in inner and outer cortexes was triggered by AM fungi firstly, then diffused through intercellular space, and accumulated in vascular tissue.

因此，GUS活性的组织表达特异性结果进一步证实了SA在AM真菌诱导的抗／耐线虫病害的ISR信号传导途径中起着重要的信号物质作用。

Even the simplest life such as AIDS virus, colibacillus, eelworms and mosquitoes has a far more complicated structure than machine like automobile or TV does.

即使最简单的生命，如艾滋病毒，大肠杆菌、线虫、蚊子，它们的构造也是极复杂的，远远超过汽车、电视机等机器，但这些复杂体却能按DNA 中暗藏的指令，自下而上地建造起来。

Proper rotation and use of disease-resistant varieties will help, but sooner or later the old garden spot becomes so full of various disease spores and nematodes that you cannot grow a good crop of many vegetables without use of special soil fumigants.

适当的轮换和使用抗病品种会有所帮助，但迟早旧花园现场变得如此充满各种疾病孢子和线虫，你不能生长良好的作物，许多蔬菜未经使用特殊的土壤熏蒸。

The sedimentary environment, abundance and biomass of meiofauna, community structure and biodiversity and systematics of free-living marine nematodes, were quantitatively studied at the middle intertidal zone during the periods of investigation.

2004年10月到2005年10月对青岛太平湾进行了连续13个月的小型底栖生物的调查采样，对小型底栖生物栖息的沉积环境、小型底栖生物的丰度和生物量、自由生活海洋线虫群落结构、多样性和分类学进行了研究。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
