By the single zircon U Pb dating method, the quartz syenite porphyny yielded an age of concordance (1 731±29)Ma, and the aegirine augite syenite and syenogebbro are dated upper cocordi...

应用单锆石U Pb法测定年龄，石英正长斑岩谐和年龄为( 1731± 2 9)Ma ，霓辉正长岩、正长辉长岩上交点年龄分别为( 1644± 14)Ma、( 1750± 65)Ma.1650～ 170 0Ma是碱性岩浆活动热构造事件的标志，石英正长斑岩被中元古代晚期的高山河组不整合覆盖，故以 1650～ 170 0Ma作为熊耳群的上限。1650～ 170 0Ma热构造事件是华北地块重大地质事件，有可能是进一步划分中元古代重要的年龄界限。

Results The effectiveness of treating sudden deafness was closely associated with the onset time of disease and treatment in early times and associated with the degree of hearing loss ,however ,not with the age ,gender ,vertigo and tinnitus、the types of the audiometric results、hypertension or diabetes.

结果：突发性聋的疗效与年龄、性别、单、双耳发病、是否伴有眩晕和耳鸣、是否伴有高血压、是否伴有糖尿病、听力曲线类型及住院治疗时间无关，而与发病到初治的时间、治疗前耳聋程度有显著的相关性。

Using single oocyst infected techniques, three strains of Eimeria tenella, PT0705, FQ0709 and LJ0711, were obtained from classically symptomic coccidian chicken in Putian, Fuqing and Lianjiang Couties, Fujian Province. In order to compare their toxicity against chicken, healthy chicken of 14th-day and 21th-day were artificially infected with 1×104, 5×104 and 10×104 coccidian oocysts of PT0705, FQ0709 and LJ0711, respectively. The results showed that the strain PT0705 was the most toxic to tested chicken based on the clinical symptom, survival rate, weight increment and lesion grade investigations.
