In the practice it plays an important part in insect surveys, the choice of grain method, the improvement of grain storage level, the extension of storage time and the delay of grain quality deterioration. 1 Research on stored product insects in large warehouse 1.1 Community composition and structure analysis of stored product insects in large warehouse By means of GJ89 type probe trap investigation of stored grain insects and analysis of community composition and structure of large warehouse were carried out in Chongqing Beibei State Grain Reserve Depot. The results showed that there were main Lipocelis botrychophilus、 Cryptolestes ferrugineus、 Tyrophagus putrescentiae and Sitophilus zeamais etc in large warehouse

高大平房仓储粮昆虫生态学研究 1.1 高大平房仓散装储粮昆虫群落组成及结构分析使用GJ89型粮虫陷阱检测器对中央储备粮重庆北碚直属库高大平房仓储粮昆虫进行系统调查，并对其群落组成及结构进行了分析，结果表明高大平房仓储粮昆虫主要有书虱Lipocelis botrychophilus、锈赤扁谷盗Cryptolestes ferrugineus、腐食酪螨Tyrophagus putrescentiae和玉米象Sitophilus zeamais等4类，其中书虱为绝对优势种群；在粮堆垂直方向0～50cm 4类昆虫发生最多，100～150cm发生最少；4类昆虫在粮面0～50cm丰富度、优势度、多样性及均匀度4项指标均高于50～100cm和100～150cm，水平方向6个区域各项指标差异不大。

Wei Xiaoan said,"Luya Mountain almost contain most types introduced in the book the Division and Assessing of Travel Resource, it could be called a collection of all kinds of sights in China; Professor Zhu Wei Mian from China Central Academy of Fine Arts said:"Luya Mountain has the majesty of Taishan Mountain, the sheerness of Huashan Mountain, astonishing of Huangshan Mountain and beauty of Emei Mountain"; Institute of Geology and Geophysics Chinese Academy of Science said it "owns unlimited sights under heaven and agglomerates all distillates of nature.

第一个是包罗万象之&博&：&山、石、林、草、洞、湖、泉、谷、庙、关&十大系列景观共同构成了芦芽山的博大，中国著名旅游经济专家魏小安先生评价：&芦芽山几乎包含了全国《旅游资源的划分与评定》中的大部分类型，可称中国各类景观的集中区&；中央美术学院朱维眠教授说：&芦芽山兼有泰山之雄、华山之险、黄山之奇、峨嵋之秀，堪称中国各大名山的缩影，雄、险、奇、秀美不胜收&；中国科学院地质研究所的评价则是&占天下之无限风光，凝自然之全部精华&。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
