箭虫

Any arrowworm of the genus Sagitta.

天箭虫属的各种箭虫。

The high density area of Sagitta bedoti was distributed at the side of southern Chinese Coastal Current in the summer and autumn.

在水温较高的环境下，百陶箭虫高丰度区位于暖流与沿岸流交汇处偏淡水水团的一侧。

While offshore, Calanus sinicus is main dominant species, and then Muggiaea atlantica and Sagitta enflata.

对近海而言，中华哲水蚤是主要的优势种，其次是五角水母和肥胖箭虫。

Results showed that seasonal variation of species composition was not remarkable. The species whose dominance was the highest in those seasons were Sagitta enflata in summer, Sagitta nagae in winter and spring and Sagitta bedoti in autumn.

结果表明，毛颚类优势种季节交替不明显，优势度最高的种分别是：夏季肥胖箭虫、冬、春季海龙箭虫和秋季百陶箭虫。

Based on the data from eight seasonal oceanographic censuses in the Changjiang Estuary (28°00′-32°00′N, 122°00′-123°30′ E) in 1959 and 2002, this paper discussed temporal\|spatial distributions of Sagitta crassa and Sagitta enflata and effects of global warming on them in the Changjiang Estuary. The results show that the average abundance of S. crassa was less than 1.00 ind/m3, and its occurrence frequency was lower, had no aggregate feature during spring, summer and autumn.

根据1959年和2002年在长江口28°00′~32°00′N，122°00′~123°30′E海域4个季节8个航次海洋调查资料，分析强壮箭虫和肥胖箭虫丰度的平面分布和季节变化特征，并结合同步的温度资料分析不同生态类群的强壮箭虫和肥胖箭虫对环境变暖的响应。

The high density area of Sagitta enflata was distributed at the warm current side of the mixed waters formed by Taiwan Warm Current and Chinese Coastal Current and that of Sagitta nagae was located at the side of northern Chinece Coastal Current.

肥胖箭虫高丰度区往往位于台湾暖流与浙江沿岸流交汇处偏暖水的一侧，海龙箭虫高丰度区位于暖流与沿岸流交汇处偏冷水团的一侧。

The linear relation of Sagitta enflata abundance with surface water temperature was remarkablely positive. The relation of Sagitta enflata and Sagitta nagae abundances with surface salinity and that of Sagitta bedoti with surface temperature and salinity were showed respectively by Yield Density mold.

肥胖箭虫与表层温度线性关系极其显著，肥胖箭虫和海龙箭虫与表层盐度的关系以及百陶箭虫与表层温度和表层盐度的关系符合Yield Density模型。

Among the three dominant species, the aggregate intensity of Sagitta bedoti was the highest, Sagittarian nagae was the second and Sagitta enflata was the lowest.

主要优势种中，百陶箭虫聚集强度指标值最高，其次是海龙箭虫，肥胖箭虫最低。

Any of various marine worms of the phylum Chaetognatha,which includes the arrow worms.

毛颚类海虫毛颚类动物门的一种海生虫，包括箭虫

According to the zooplanktonic species composition and it's distribution in the coral reef lagoons from Nansha Islands, these zooplankton may be distinguished into three groups

栖息在珊瑚礁外的种类，它们随海流或潮流进入潟湖，它们是上层种，属於终生浮游生活的。例如浮游桡足类，浮游放射虫，浮游有孔虫，大眼端足类，箭虫，住囊虫，浮游介形类和浮游幼体等

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
