No significant genetic differentiation was displayed among rotifer clonal groups in three lake districts of Donghu Lake.

因此在武汉东湖萼花臂尾轮虫种群是由遗传距离较大，分布比较随机的克隆群组成的，种群在各湖区无明显分化。

目前，虽然对无压尾水洞引风过程的热湿处理效果有了一定的认识，并在四川映秀湾水电站中成功实施了我国第

In order to select a kind of eminent grass which is adaptable to the northern China, the present thesis studies ten kinds of grasses from Gramineae, Bromus biebersteinii,Bromus inermis,Festuca arundinacea ,Festuca rubra,Dactylis glomerata ,Phleum pratense,Agropyron desertorum,Agropyron smithii,Elytrigia elongate and Phalaris arundinacea,and also explores the physiological aspects of their drought resistance, cold tolerance and barren resistance. The drought resistance experiment was conducted to study 10 grasses under water stress during seedling stage by simulating indoor drought environment.

为了能选适应我国北方地区的抗旱、耐寒、耐贫瘠特性的优良牧草，本研究以草地雀麦、无芒雀麦、苇状羊茅、紫羊茅、沙生冰草、蓝茎冰草、长穗偃麦草、猫尾草、鸭茅、草芦为材料，在抗旱、耐寒和耐贫瘠性特性三方面的生理方面进行了探索研究。

Inflorescence a terminal panicle, raceme, or spike, dense or lax, covered by 1--3 spatulate involucral bracts when immature; bracts open to base, rarely hooded, each subtending 1 flower or a cincinnus of 2 to many flowers; bracteoles open to base or tubular, rarely hooded, sometimes absent.

花序一顶生圆锥花序，总状花序，疏松的或穗状花序，紧密或疏松，未发育完全时被1-3匙形总苞片覆盖；苞片打开至基部，很少盔状，每苞片着生1花或蝎尾状聚伞花序的2到多数花；小苞片打开至基部或管状，很少盔状，有时无。

RESULTSThe branches of aortic arch are the left and right innominate artery in pate of mini-pig.

结果小型猪主动脉弓部向头颈部分支为左、右无名动脉；双侧颈内动脉均来自右无名动脉，故右无名动脉对脑底供血十分重要；双侧有沿脊柱向尾侧走行的折返动脉；胸主动脉背侧由胸6至胸14平面共发出8条肋间动脉，为胸腰脊髓的主要供血动脉；无腰大动脉。

Results The micronuclear rate in medium dosage group and high dosage group were significantly higher than that of control group(P＜0.01). The ratio of sperm malformation in middle group and high group were higher than those of controls (P＜0.01).The ratio of sperm malformation increased in dose-dependent manner with dose, a dose-response relationship was found. Conclusion The DBP contamination presents the positive results under the certain dosage to the mouse marrow micronucleus experiment and the spermatozoon abnormal experiment.

结果 中、高剂量组微核率与阴性对照组相比明显升高(P＜0.05)，且各剂量组微核率随染毒浓度的增加而升高，呈现剂量-反应关系(r=0.937，P＜0.01)；中、高剂量组精子畸形率与阴性对照组比较差异有统计学意义(P＜0.05)，且各剂量组精子畸形率随染毒浓度的增加而升高，呈剂量-反应关系(r=0.904，P＜0.01)，畸形精子中以无钩为最多，其次是香蕉形、尾折叠、双头，分别为4.5%、3.09%和1.32%，结论 DBP染毒在一定剂量下对小鼠骨髓微核试验和精子畸形试验呈现阳性结果。
