A pulsator for a washing machine is provided, which comprises: a main body installed on a bottom of the washing tub, and having a fan chamber and a upper surface formed with at least a spout outlet; a spout fan having a fan shaft and a plurality of fan blades extending radially from the fan shaft, the spout fan rotates relative to the main body to eject washing water upwards through the spout outlet; a bearing means for rotatably supporting the fan shaft in a radial direction as well as an axial direction; and means for rotating the spout fan.

一种洗衣机波轮，包括：一个安装在洗衣筒的底部的主体，具有叶轮室以及形成有至少一个喷水出口的上表面；一个具有叶轮轴和多个从叶轮轴沿径向延伸的扇叶的喷水叶轮，该喷水叶轮相对于主体旋转从而产生向上的洗涤水流；可在径向以及轴向上旋转支承叶轮轴的支承部件；以及使喷水叶轮旋转的部件。

In the leaves of Liriodendroideae, some of the abaxial epidermal cells are papillose and the vascular tissue of the main vein appears to be separated. However, papillose were not found and there are uniseriate, multicellular or unicellular hairs distributed on the epidermis, and the vascular tissue of the main vein appears to be continuous in the leaves of Magnolioideae. Furthermore, in the Magnolioideae, the structure of the leaves of plants in Manglietia are different from that of Magnolia.

结果表明：鹅掌楸亚科和木兰亚科在叶的结构上的主要区别是鹅掌楸亚科两种植物叶的部分下表皮细胞呈乳突状，且整个细胞外壁只形成一个乳突，而在木兰亚科的植物中有单列多细胞或单细胞的表皮毛，未发现乳突；鹅掌楸亚科植物的叶主脉维管组织环分隔呈束状，且其外包被的纤维也排列成束状，而木兰亚科的80种1亚种植物中，叶主脉维管组织连成轮状，其外面也由一圈连续的纤维环所包围。

In this paper, we studied the effect of Hg(superscript 2+), Cd(superscript 2+) and their combined pollution on Myriophyllum verticillatum Linn.

研究了Hg(上标 2+)、Cd(上标 2+)及其复合污染对轮叶狐尾藻的毒害影响。

The effect of different phosphorus nutrition conditions（0.02、0.1、0.2、0.4、0.8 mg·L-1）on the growth of the macrophytes Myriophyllum spicatum and Hydrilla Verticillata was investigated.

实验研究了不同质量浓度（0.02、0.1、0.2、0.4、0.8 mg·L-1）磷对穗花狐尾藻和轮叶黑藻生长状况的影响。

The results demonstrate that Myriophyllum spicatum could tolerate higher phosphorus concentrations than Hydrilla Verticillata. However, the optimal phosphorus concentrations for the growth of both Myriophyllum spicatum and Hydrilla Verticillata exceed the phosphorus concentrations in eutrophic water bodies.

实验结果表明，穗花狐尾藻比轮叶黑藻更能耐受高质量浓度的磷，并且两种沉水植物适宜生长的磷质量浓度都高于目前富营养化湖泊水体中的磷质量浓度，也远高于湖泊富营养化的磷质量浓度标准（0.02 mg·L-1）。

Leaves verticillate and alternate apically on stems, verticillate basally on old stems

The pulley or fan bore shall be concentric and match the diameter of the rotor shaft.

风叶和皮轮必须无磨损或损坏，皮轮不应有碎屑，弯曲或其它瑕疵会干预驱动器皮轮的正常运转，皮轮和风叶孔应同心并与转子轴的直径相匹配。

The main influential factors on the change of community structure were discussed in this paper. It was thought that the inherited attribute of plant decided the dominance of E. nuttallii and H. verticillata in local plant community; and the herbivory preference of the snail on P malaianu and V spiralis speeded up the occupancy of dominance by other 2 plants.

作者对调节沉水植物群落结构的影响因素进行了探讨，认为植物种类的生长特性使伊乐藻与轮叶黑藻在与苦草及马来眼子菜的竞争中占优势，椭圆萝卜螺的牧食损害则加速了这种优势地位的取得。

It is consisted of horizontally placed shell and revolving shaft with function of steam heating; The heating flat plate mounted with angle-adjustable paddle is welded to the shaft.

它是由一个横卧的外壳和一个带有蒸汽加热的转轴构成，轴上焊有加热平板，平板上装有可调节角度的轮叶。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
