不操作

If the data of a path can not been found in the abstractor definition, then it is not generalized and is pruned. The basic principal of hierarchy tree has two steps.

若某路径上对应的数据不能在概念层次树上找到更为抽象的定义，无法对该数据进行概化操作，则认为其是与挖掘任务关系不大的，执行剪枝操作。

由于操作系统要求的安全性较高，系统盘默认的安全策略是操作系统不保存用户对系统盘所作的任何操作，而用户数据要求的安全可靠性相对较低，灵活性较高，用户盘默认的安全策略是操作系统保存用户对用户盘所作的任何操作。

In this example, the first addend at any time is considered to be selected by attention, but those unused in the current operation not.

在这个例子中，当前被选择用于加法操作的数字被注意所选择，而其他那些不用于当前操作的数字则并未被注意选择。

The examination falls into two parts: the written test and the operation test. The written test is to check one's basic electric knowledge, which includes electric control theories, installation standards, etc. The operation test is a bit difficulty. Firstly, you have to connect several major loops and control loops appointed by the examiner within limited time. If you do right, the electricity is connected, the bell rings and the light turns on, then you will pass the test; but if it explodes and emits smoke, then you will not only get zero score but be scolded. Life is not a game, and one should never pretend to know things that he does not know.

考试分笔试和操作二项，笔试的内容都是最基本的电工知识，电气控制原理，电气安装规范等等，而考操作就有难度了，首先要你在规定的时间里接好考官指定几的主回路和控制回路，接对了，通上电，灯亮铃响顺利过关；若是爆炸冒烟，那不仅没分还要挨骂，生命不可儿戏，不懂不能装懂。

For long time,my factory prints a version to electroplate a group in addition toimport of the nickel urn is full-automatic, other of fiveelectroplates slot almost is depend on moving an operation tocontrol to electroplate of temperature, electric current and timeof, print a version to plate chrome especially, with its specialoperation craft and the high causticity, the long-term existenceproduct quality unsteady problem, can not keep up with the requestthat assurance product quality unifier.

长久以来，上海印钞厂"娴缍菩∽槌了进口的镍缸是全自动的，其它的五个电镀槽几乎都是依靠手动操作来控制电镀时的温度、电流和时间的，特别是"娑聘酰以其特殊的操作工艺和高度腐蚀性，长期存在产品质量不稳定的问题，跟不上保证产品质量的统一性的要求。

You should make affairs be simple and exact if you could not find out main market development method, then you could improve your executive power, or you could not get unpleased result at last even you pay great efforts.

虽然市场操作方法千万种，但适合于我们的只有几种，任何企业的资源都是有限的，如果你不能找到发展市场的主线，把复杂的事情简单化、准确化，变为自己可以执行的、落实的工作，而提高企业的执行力，那最后只能像无头的苍蝇，虽然付出巨大的努力，其结果不仅不会尽如人意，反而会使执行成本越来越高、实际操作结果越来越差

Professional collages are special collages which are merged and composed ineducation reform of our country.They have remarkable features: campuses scattere, amount and levels of students more, lacking of teachers and managers, operation ofmanagers not unite.Facing these new conditions and Problems, the old managingmode cant suit the development of professional collages.

高职院校是在我国教育改革中出现的特殊高等院校，高职院校通过合并，重组而建，具有其显著的特点：校区分散，学生数量大、层次多，教师及管理队伍严重不足，管理人员操作不统一，面对这些新情况，新问题，以前的管理和操作方式都不能适应当前学院发展的需求。

Since every rebounce happens when the plates move around, you would not always favour some plate.

如果不会操作T+0的，即使是前期被套的个股，在技术性反弹时，是中小盘活跃股，最好持股不动，不要频繁操作。

However, it can only implement the limited operation to the spatial objects, cannot carry on transformation, index, interlink age and excavation to the spatial data, and hard integrate other information with combining map variable to set up and analysis new variable. Meanwhile, relational model in the traditional DBMS and the object- oriented modeling do not completely suit the spatial application domain. The relational model can handle topological relation well, but shows inabilities to that complicated level crossing the spatial region. Object-oriented model using software method based on the principle of the customer defined data type supports the abstract data type, especially spatial abstract data type, and possesses polymorphism and inheritances, and it can deal with topological and the layer relation, but hardly processes important continuous phenomenon in space.

GIS是当今操作有关空间信息的成熟工具和技术，但其只能对空间对象进行有限的操作，不能对空间数据进行变换、索引、链接和挖掘，难以集成其他信息来构建和分析新变量；而传统数据库管理模型中的关系模型和面向对象建模也不完全适合空间应用这一领域，关系模型能够较好地处理拓扑关系，但对表示横跨空间区域的复杂层次却无能为力；面向对象模型的软件方法支持抽象数据类型，特别是空间抽象数据类型，具有继承性和多态性，能够处理拓扑和层次关系，但难以处理空间中重要的连续性现象。

In the view of the situation of the efficient grader in Panzhihua iron and steel company,which have hard operations,delaying action and changeable technological parameter,we have designed a control system to realize the auto regulation to the puple density.

针对攀枝花钢铁集团公司选钛厂运行的新型高效分级浓缩箱一室排矿浓度手工操作劳动强度大、操作不及时、工艺指标不稳定等问题，研制了对一室的排矿浓度进行自动调节的自动控制系统。

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。
