This paper from squirrel food availability,food composition,the selectivity of foodresource,take edible behavior and energy countermeasure for food nutrition quality and theform structural feature of alimentary canal and few aspect such as seasonal adaptabilitychange as well as nutrition condition appraisement of population carry out research as redsquirrel nutritional adaptive strategy.At the same time for go on preliminary discuss thegenetic diversity of red squirrels from Daxingan Mountain,Xiaoxingan Mountain,respectively.The result was considered:1squirrel forage plant can use existent obviousseasonal change.

本论文从松鼠食物的可利用性、食物组成、对食物资源的选择性、食物营养质量、取食行为和能量对策、消化道形态结构特征及季节适应性变化以及种群营养状况评价等几方面对东北松鼠营养适应对策进行了研究，同时对大、小兴安岭两个地区松鼠种群的遗传多样性进行了初步的探讨，结果认为：1松鼠饲料植物的可利用性存在明显的季节变化。

Based on the study of chronology and geochemistry of Cd in sediments of the Dongting lake area, we have established an ARIMA model of Cd and Cd/Ca in Quaternary and Holocene period respectively, and discussed Cd evolutionary regularity according to the fitted value and predicted value of the model The results revealed that the Cd evolution has remarkable periodicity of ecogeochemistry cycles, and is correlated with the climate change of alternative cold and warm Cd/Ca is changed with climate, from which the evolutionary history of regional ecogeochemistry can be inferred The changes of Cd and Cd/Ca are basically simultaneous, which showed that the change of Cd is mainly a natural evolution Cd in sediments will rise in the next 30 years and then tend to decrease From the regularity of ecogeochemistry indexes and global environment variation, it is concluded that the natural environment is the dominant factor affecting the Cd deposition

在对洞庭湖区沉积物钻探取样的年代学和地球化学研究基础上，分别建立第四纪和全新世时期Cd和Cd/Ca的时间序列演化ARIMA模型，并据模型的拟合值及未来预测值对区域地球化学环境中Cd的演化规律进行了探讨，结果显示区内Cd的演化有较显著的周期性--环境地球化学旋回，与气候多次冷暖的交替有关；沉积物Cd/Ca受气候环境等控制，分析该比值的变化规律可推测区域环境地球化学的演变历史；Cd和Cd/Ca两者的变化基本同步，说明该区Cd的演化主要为自然演化；未来30年内沉积层的Cd含量仍有逐渐增高的趋势，之后转为降低。从本区环境地球化学指标的时间变化规律及其与全球环境变化的相关联中说明自然条件是区域镉等元素沉积的主控因素。

Leakage in the initial observation to determine the basis of the leakage site, and then manually set car observation, if the leakage were no significant changes in static and dynamic sealing ring problem; such as the disk when there are significant changes in leakage can be concluded that the dynamic , static friction ring problems; such as leakage of medium along the jet axis, w你好le moving most of Central ring problems, leakage to the surrounding medium or from the water spray cooling holes in the leakage, the seal ring for static failure.

杂质泵安装静试时泄漏机械弥缝安装调试好后，一般要进行静试，察看泄漏量如泄漏量较小，多为动环或静环弥缝圈存在问题；泄漏量较大时，则表白动、静环磨擦副间存在问题在开端察看泄漏量、判断泄漏部位的根蒂根基上，再手动盘车察看，若泄漏量无明显变化则静、动环弥缝圈有问题；如盘车时泄漏量有明显变化则可下定论是动、静环磨擦副存在问题；如泄漏介质沿轴向喷洒，则动环弥缝圈存在问题居多，泄漏介质向四周喷洒或从水冷却孔中漏出，则多为静环弥缝圈失效此外，泄漏通道也可同时存在，但一般有主次区分，只要察看细致，认识结构，一定能正确判断
