Some plants rely on wood part of the negative pressure, through its non-metabolic ultrafiltration to separate freshwater from seawater, such as K. candel, Ceriops tagal, etc.; Some plants, such as Avicennia marina, Aegiceras other is through their own system of salt gland salt inhalation secretion of the leaf surface, washed away by rain.

有些植物依靠木质部分负压力，通过其非代谢性超滤作用从海水中分离出淡水，如秋茄、角果木等；有些植物，如白骨壤、桐花等则是通过自身盐腺系统将吸入盐分分泌出叶片表面，经雨水冲刷掉。

The results showed that the freshwater species were predominant, and 45 species of algal (5 phylums, 32 genera), in which 18 species of Bacillariophyta belong to 12 genera, 15 species of Chlorophyta one genus, 10 species of Cyanophyta 7 genera, and one specie of Euglenphyta and Chrysophyta; 37 species of zooplankton, in which 9 species of Protozoa, 14 species of Rotifera,...

结果表明，淡水种类占绝对优势，藻类5门32属45种，其中硅藻12属18种，绿藻1属15种，蓝藻7属10种，裸藻、金藻各1属1种；浮游动物共计37种，其中原生动物9种，轮虫14种，枝角类2种，桡足类8种，浮游幼虫及其它4种；底栖动物20种，分别为环节动物的多毛类7种，寡毛类2种，软体动物8种，甲壳动物2种，鱼类1种。

The freshwater pearls and the seawater pearls are different baddish commodities,just like jade and emerald.Seawate pearls should be chosen on the following five criteria

淡水珠和海水珠是属于二个不同档次的商品，就象岫玉与翡翠不可相提并论，选购海水珍珠的应着重按以下五个标准

Is a small freshwater alga suitable to live in an environment where both water temperature and light intensity is relative low. The optimum water temperature of 15℃ and the optimum light intensity of 35μmol/m^2s~45μmol/m^2 s are needed for photosynthesis of Batrachospermum longipedicellatum.

其光合作用的最适水温为15℃，光合作用的适宜光强为30μmol/平方公尺s~50μmol/平方公尺s，最适光强度为35μmol/平方公尺s~45μmol/平方公尺s，40μmol/平方公尺s光合速率最高峰，为其饱和光强。

But if that theory is correct then bdelloid rotifers, freshwater invertebrates that haven't had sex in at least 30 million years, should have been parasited into extinction long ago.

但是如果这个理论是正确的，那么蛭形轮虫（一种淡水无脊椎动物，它已经无性繁殖至少3000万年了）应该在很早以前就被寄生虫消灭了。

But if that theory is correct then bdelloid rotifers, freshwater invertebrates that haven't had sex in at least 30 million years, should have been parasited into extinction long ago.

但是如果这个理论是正确的，那么蛭形轮虫，这种至少已经存活了3千万年的无性繁殖的淡水无脊椎生物，应该早就因为感染寄生虫而灭绝了。

The researchers, based at Cambridge University, focused on bdelloid rotifers, female microscopic organisms that live in freshwater pools.

剑桥大学的研究者们对生活在淡水池塘中的雌性微生物蛭形轮虫进行了研究。

Bdelloid rotifers, microscopic asexual freshwater invertebrates are the ultimate escape artists, able to outpace their enemies by drying up and blowing away.

蛭形轮虫，只能在显微镜下观察的无性淡水无脊椎动物是最好的&脱身专家&，它们通过&干枯&和&随风吹走&来超越竞争对手。

Bdelloid rotifers (pronounced DELL -- oyd ROWtiff-ers) are tiny, freshwater invertebrates that have long puzzled scientists because, as completely asexual animals, they should have been extinguished by parasites and pathogens long ago in evolutionary time.

蛭形轮虫这种细小的淡水无脊动物已经困扰科学家们很长时间了，因为作为一种无性生殖动物他们在进化中早就应该因为寄生虫和病原体而灭亡了。

You can snipe the second and third union leaders from this position.

您可以鹬第二和第三工会领袖从这一立场出发。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
