入侵

Worked out a concrete goal for biodiversity conservation in the area, including to maintain and protect the speciality and intactness of the combined ecosystem of rivers and lakes, to protect freshwater resources, to maintain and restore the natural hydrolgical process of the river system of the area, to protect the core species and their habitats efficiently, to protect and restore the typical zonal vegetation (the subtropical evergreen broad-leaved forest), to forbit introducing the invasive species, and to eliminate or control the settled invasive species.

制定了长江中游生物多样性保护的具体目标，即维持和保护江湖复合生态系统的独特性和完整性；保护淡水资源；维持和恢复长江中游水系的自然水文过程；有效保护核心物种及其栖息地；保护和恢复典型的地带性植被；禁止引进入侵性物种，消灭或控制已经定居的入侵性物种。3。

The study indicates that sea water and brine intrusion processes have different hydrochemical features;and that ion exchange and absorption actions between water and aquifer produce great influence to the intrusion.

研究表明，现代海水、卤水在入侵过程中的地下水水化学特征有明显不同；地下水与含水岩层间的离子交换与离子吸附作用对咸水的地下入侵过程产生重要影响。

In southern Taiwan, the great propagation of the Leucaena leuococephala has already caused the ecological invasion and threatened the existence of the native vegetation species. Therefore, to monitor the invasion of leucocephala is an important conservation issue in Kenting National Park.

银合欢在南台湾大量繁殖，己造成生态入侵而严重威胁垦丁国家公园内原生植物的生存，因此银合欢入侵监测成为垦丁国家公园的重要保育课题。

Based on a survey on exotic invasive plants of Shenzhen's green space ,this paper confirms that Mikania micrantha and lpomoea cairica are the most harmful exotic plants in the city.

通过对深圳市具有代表性的公共园林绿地中的外来入侵植物的调查，确定薇甘菊和五爪金龙为深圳市为害最为严重的外来入侵植物。

Mikania micrantha is notorious for its strong ability to colonize in new habitats. Existing photosynthetic studies have mainly focused on leaves, and less on non-photosynthetic organs such as stems, roots, and reproductive organs.

薇甘菊因为其在新生境的强入侵能力而臭名昭著，有关其入侵的光合生理原因主要集中在叶片光合速率研究，而对非同化器官光合特性少见报道。

Future studies are recommended to compare the impacts across multiple scales and multiple ecosystems; intensify mechanical studies of the impacts; link the impacts on biodiversity and ecosystem processes; and explore the mutualistic interactions between soil ecosystems and exotic plants.

今后，加强多尺度和多生态系统的比较研究、机制性研究、生物多样性和生态系统过程的整合性研究及土壤生态系统对植物入侵的反馈研究是评价外来植物入侵对土壤生态系统影响的发展趋势。

I.. The virions were observed in the cylindrical cell at 9 h p. i.. The intact virions probably penetrated through the peritrophic membrane, then absorbed and invaded the microvilli for infecting the cylindrical cells.

作者认为病毒入侵是以整个病毒粒子穿越中肠围食膜，吸附并进入微绒毛，感染圆筒形细胞，与前入病毒入侵只是髓核进入细胞，而病毒衣壳仍留在细胞外的推测不同。

There are 2 main pathways by which schistosomes cause NS: egg embolism and worm migration, via either artery or vein system, especially the valveless perivertebral Batson's plexus. The adult worm migrates anomalously through the above pathways to the CNS where they lay eggs.

关于中枢神经系统血吸虫病虫卵入侵途径，目前主要存在虫卵栓塞和成虫产卵两种学说，前者分为动脉栓塞、静脉栓塞和Batson椎静脉途径，成虫亦可循上述途径入侵中枢神经系统产卵。

At first, the procreant background and the development process of intrusion detection system was introduced.

首先介绍了入侵检测系统的产生背景，以及入侵检测系统的发展历程。

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。
