The results showed that,the sound pressure level increased significantly when narrow transverse groove was used;the effect of speed on the sound pressure level was greater than loading;the noise of S-shaped straight groove was lower,and the difference of sound pressure level between positive and negative rotation was small;the sound pressure level of 15° oblique groove was higher than 0° and 15° alternate groove,but the difference of sound pressure level between positive and negative rotation of 0° and 15° alternate groove was bigger.

结果表明，无论加刻什么类型的横向细沟槽，声压级都大幅升高；速度对声压级的影响程度大于负荷；在3种类型的横向细沟槽中，S形直沟槽噪声较小，且正、反转时声压级差异小；15°斜沟槽声压级较0°与15°交替排列沟槽略高，但0°与15°交替排列沟槽的正转和反转声压级差异较大。关键词：轮胎；轮胎噪声；胎面花纹；横向细沟槽中图分类号：TQ336.1；TB533+。2文献标识码：B文章编号：1006-8171(2009)

Specimens were examined by histological method to determine the cycle of the gonad development of this nemertean. The results showed that: The sex ratio (female: male) was about 1: 1. The sizes of mature males and females were not significantly different; females are rosy in colour and males are white, largely owing to the metamerically arranged gonads. Gonads, which were not detected in samples of autumn months, arose in December, but sexes were indistinguishable until middle January.

结果表明：扁额原细首纽虫雌雄比例约为1：1；雌雄体长、体重无显著差异；性成熟雌体通常体壁呈玫瑰红色，雄体呈白色，非繁殖季节雌雄体色无明显差异；一年有两次性腺发育，第一次12月开始出现性腺，1月可辨雌雄，3月15日达到第一次性腺发育高峰，4月15日性腺消失；第二次于4～5月开始出现性腺，6月15～30日达到高峰，9～10月性腺消失。

The result indicated that the percentage of lymphocyte were decreased, the percentage of neutrophile granulocytes were magnified significantly with the lighting time increasing, which was due to the level of the melatonin inhibited in the long time lighting; and to supply different exogenous dose, induce the percentage of lymphocyte were magnifying, the percentage of neutrophile granulocytes were decreased. And the statistical analysis showed there was significant difference.

结果表明：在给予不同光照时间的条件下，随着光照时间的延长，褪黑素的分泌水平受到抑制，导致具有特异免疫功能的淋巴细胞百分率下降，具有非特异免疫功能的中性粒细胞百分率上升，经统计分析表明不同组间的测定结果均存在显着差异；采用24h全天光照，用以模拟机体切除松果腺的情况，再给予一定剂量外源性褪黑素，导致机体内具有特异免疫功能的淋巴细胞百分率上升，具有非特异免疫功能的中性粒细胞百分率下降，经统计分析表明不同组间的测定结果均存在显著差异，并且高剂量褪黑素对机体的影响更为明显。
