保持

So for celibate rotifers that want to stay clean, a good long dry spell is just what the doctor ordered.

蛭形轮虫要是想保持清洁，不感染真菌的话，就多听专家的话，保持一段较长时间的干燥状态吧。

For the first time, a screw pile and pile driver system for preventing flood and rushing to deal with an emergency was manufactured. The screw piles of the system is different from screw drills used to sap, and it doesn't push soils out. Analyses, including the screw pile's structural strength analysis and the screw blade's welding analysis, were done by ANSYS, which showed that the screw pile's structural strength is enough and that the distort of the screw blade is small. Testing on the screw pile and pile driver system showed that the system performed stably and could meet the need of preventing flood and rushing to deal with an emergency. A mechanics model of interaction of a screw pile and soil was built, and expressions of torque of screw pile's cylindrical part on the condition of screw pile's crew part being driven into soil fully were gained, then the relation of the torque with screw pitch and out diameter of cylinder, which shows the torque decreases with the screw pitch increasing, and that the torque increases with the out diameter of cylinder increasing, which was according with the experiments of the screw pile's being driven into soils, and thus a screw pile with the best structure was chosen. Experiments of bionic surface showed that, on the condition of certain pressure on the surface, the protruding bionic surface can not reduce adhesion and resistance and that the corrugated bionic surface can reduce adhesion and resistance. An orthogonal experiment of the corrugated bionic surface was done with the factors including the width of protrusion, the space between two protrusions, the trolley's velocity and the vertical surface pressure and with the surface frictional coefficient as the experimental target, and some inclusions were drawn that the best combination of the factors was acquired and that the width of protrusion affected the surface frictional coefficient remarkably.

研制了防汛抢险螺旋桩机系统，提高了沉桩作业效率；利用ANSYS对桩体进行整体结构强度分析以及螺旋叶片的焊接分析，表明桩体结构强度足够，焊接过程中，螺旋叶片的变形小；对整个螺旋桩机系统进行试验，表明该系统性能可靠，工作稳定，作业效率高，能够满足防汛抢险沉桩作业基本需要；建立了螺旋桩桩土作用力学模型，得出螺旋桩沉桩过程中螺旋桩螺旋部分完全进入土体时螺旋桩圆柱部分所受扭矩以及扭矩与防汛抢险螺旋桩的螺旋导程和圆柱外径的关系曲线，表明螺旋桩螺旋部分完全进入土体时螺旋桩圆柱部分所受扭矩随着螺旋导程的增大而减小，随着圆柱外径的增大而增大，这与螺旋桩沉桩试验结论相符合，据此优选出最佳结构的螺旋桩；仿生曲面试验表明，尺寸较小的球冠突起型仿生曲面在一定压力作用下未能起到减粘降阻的作用，而尺寸较大的波纹型仿生曲面相对平板具有一定的减粘降阻作用；以波纹型仿生曲面突起宽度、波纹型仿生曲面两突起之间间距、台车的牵引速度以及叶片表面垂直载荷为因素，以曲面摩擦系数试验指标进行正交试验，寻求出在一定试验条件下最佳因素水平组合；波纹型仿生曲面突起宽度在本试验条件下对曲面摩擦系数影响显著，而其它几个因素对曲面摩擦系数影响均不显著；通过波纹型仿生曲面突起宽度和台车牵引速度的单因素试验，表明曲面摩擦系数随着仿生曲面突起宽度的增大而减小，而随着台车牵引速度的变化基本保持不变，和正交试验结果保持一致。

Maintain the body, including maintaining the parts and connectors, connectors can be connected with a bone plate in the far Department.

Because of the low efficiency of economy collectivization, collective property rights can"t last for a long time and central government has to communicate with community and peasants. Rural community collective property rights become subjective through balancing benefits by formal or informal trading. With the changes of political and economical environment, the contradiction of rural community property rights between fair and efficiency become more and more serious. Collective lands and collective enterprises advance to privatization gradually. There are two kinds of country collective property rights in the history of its evolution, one offer community common good and the other satisfy peasants" private demand. The collective property rights institution improvement brings efficiency because it privatizes the latter. Because of the limit of industrialization and civilization, land is still the last social welfare of peasants, so rural community must attain the collective property rights to control the pressure of population. Also community has to get money from collective economy.

本文分析的思路是；由于制度变迁的&路径依赖&，农村社区之间的利益分配边界在解放以后得以保持并在集体化过程中得到加强，为社区获得排他性集体产权奠定了基础；由于国家对农村经济的集体化效率极低而不可能长期维持，国家不得不与社区和农民对话，通过正式或非正式的交易平衡多方利益，社区集体产权获得实质性内容；随着政治、经济等环境的不断变化，社区集体产权公平与效率之间的矛盾同益明显，集体土地和集体企业逐渐朝私有化的方向发展；从农村社区集体产权制度变迁的历史来看，集体产权实际上包含两种形式：提供社区公共物品和满足社区农民个人需求，每一次集体产权的制度创新，都是使后者&私有化&而提高了集体经济的效率；但是，受我国工业化和城市化进程缓慢的制约，土地依然是农民最后的生存保障，农村社区必须保持对土地的集体产权以调节人口变化对土地的压力，社区组织行使职能也必须有一定的集体经济提供资金支持。

The model well mimicked the hearts in vivo. Perfusions were performed at a constant 1. 5kPa left atrial preload and 10.7kPa aortic afterload.
