对鳃

The selective response of three chafers to different plant leaves The number of beetles caught by castor-oil plant leaves were obviously more than that of control filter paper, cotton, sweet potato, soybean, Abutilon theophrasti Medic, peanut and elm leaves.

铜绿丽金龟和暗黑鳃金龟对花生、榆树、大豆的取食量都比较大。该结果说明，金龟甲对蓖麻的趋向行为可能不是为了取食或者说不单单为了取食，是否具有引诱其交配、产卵、栖息等行为，都是疑点，需要进一步研究。

This may be due to hydrolytic chelating, precipitation and the sediment or hydrobioes attachment, absorption etc. The honewort had stronger ability of accumulating La because of its large leaf surface that could attach La. The accumulating ability of snail and fish to La was relatively weaker but some organs of them had higher contents of La especially in the intestines, shell of snail, and in gill, internal organs, scales, head, bone of fish, rare in muscle. The total accumulating quantities of La in each component of simulated aquatic ecosystem were a decreasing order of: sediment ＞honewort＞snail＞fish, and the sequence of bio-concentration facter was as follows: honewort＞snail＞fish.

2金鱼藻对La有较强的富集能力，主要通过枝叶表面吸附、吸收而富集；螺蛳对La也有一定的富集，并主要分布于肠、壳中，螺头中积累相对较少；草鱼对La的富集能力相对较弱，进入鱼体的La主要集中在鳃、内脏、鳞及头、骨中，肌肉中积累量较少；按质量计，稀土元素La在模拟水生态系统各部分中的积累量依次为：底泥＞金鱼藻＞螺蛳＞草鱼；各水生生物对稀土La的生物富集因子依次为：金鱼藻＞螺蛳＞草鱼。

Concentrations of free copper and mucus and other parameters including pH and alkalinity of the gill microenvironment of Cyprinus carpio exposed to copper of various levels were determined using Playle's apparatus.

利用 Playle设计的装置测定了不同铜暴露水平下鲤鱼鳃部进出水中的游离铜离子浓度、粘液含量及有关参数。用MINTEQA2和单配位体模型联合的试算方法计算了不同形态铜含量以及鳃部粘液对铜的络合能力。

The ultrastructure of the gill surface in largemouth bass Micropterus salmoides and blue gill Lepomis macrochirus was investigated using scanning electron microscopy.

应用扫描电镜对大口黑鲈Micropterus solmoides和蓝鳃太阳鱼Lepomis macrochirus鳃的表面微细结构进行了观察。

This study consisted of two sections, the one is about the relationshipe between ear and jaw, the other is about the comprehensive treatment for microtia.

在我国，近年来各地相继开展了耳廓再造手术，晚近又有同期进行中耳成形术的报道，在手术设计方面进展较大，但对小耳畸形和颌面部畸形的关系至今尚未见到有关的研究报道，对第一、二鳃弓综合症缺乏足够的认识，反映在对小耳畸形的治疗上也缺乏全面考虑。

Hemagglutination activity of lectin samples after treated under different condition was tested, and its stability was evaluated; and agglutinating effect to the microalgae cells and microorganism were observed by an inverted microscope.

方法］测定经各种条件处理过的鳙鳃凝集素样品的血凝活性，评价其稳定性；通过镜检测定鳙鳃凝集素对微藻细胞及各种微生物细胞的凝集作用。

The result shew, Chromatin broke into pieces which dispersed around the irregular nucleus, nuclear outer member disintegrated; Mitochondria condensed, cristae of which disintegrated partly; The endoplasmic reticulum dilated, vesiculated, gradually disintegrated; A great number of dense granules appeared in the cell. To sum up: Enrichment of heavy metals in Eriocheir sinensis, Macrobrachium nipponease, Cipangopaludina cathayensis is obviou""

综上所述：我们首次证明上海地区沼虾、河蟹、园田螺对重金属元素富集能力要明显强于淡水鱼类；肝、鳃是鱼、虾、蟹体内重金属富集的主要部位；Hg和Cr为高富集元素，Cd是中富集元素，Cu和Pb为低富集元素；罗氏沼虾对镉离子和锌离子的96小时的半致死浓度（LC50）分别为0.115mg/L和0.68mg/L；首次证明锌离子、GSH在一定范围内可以抵抗镉离子对罗氏沼虾肝胰脏破坏。

In this "five-step", the evolution of the first step in the series of groups of animals very strange: 14 more haikou insect specimens comparative anatomy studies show that, they not only, and the lack of chordomas in skin, muscle, breathing, circulation, neural organs such as the system with the fundamental difference between the existing chordates, One of the most distinctive is the gills of six foreign composed of respiratory system, and this is the mouth of higher animals in the gills.

在这分&五步走&的演化系列中，&第一步&的动物类群十分奇特：对1400多枚海口虫标本进行比较解剖学研究表明，它们不仅缺少脊索构造，而且在皮肤、肌肉、呼吸、循环、神经等器官系统上与脊索动物存在着根本差别；其中最为独特的是其由6对外鳃组成的呼吸系统，这与较为高等的后口动物的勤鳃迥然有别。

In this paper the direction of blood flowing and electron scanning on the transverse section of gill have been described and four histochemistry methods have been used to describe the functions of three systems as mentioned above.

扫描电镜观察发现，入鳃血管的侧壁上有成列的卵圆形孔，这些孔与鳃丝相通。采用汞溴酚蓝等4种方法，对上述几种结构分别进行了组织化学研究。

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。

In slot 2 in your bag put wrapping paper, quantity does not matter in this case.

在你的书包里槽2把包装纸、数量无关紧要。
