查询词典 variable

In this study, two models to fit soil three-variable characteristic surfaces of different soils were proposed based on the Brooks-Corey soil water retention curve model. Advantages, disadvantages and application conditions of the two were illuminated. In addition, soil three-variable surfaces measured for packed soil samples through centrifuging and controlling bulk density using paraffin material were used to verify the proposed models.

Taking the theory of Customer Satisfaction and Uses and Gratifications as the frame, this paper is to design the model of channel satisfaction, and put forward structured variable and observed variable in the model.

内容提要：本文以&满意度理论&和&使用与满足理论&为理论框架，设计出电视频道满意度评估模型，提出并分析了频道满意度模型的结构变量和观察变量。

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。

The conclusion is: There is a long-term equilibrium relationship between rural surplus labor force transfer and economic development ; In the long run, they have a positive correlation, and the former is the latter's onesided Granger causality ; And in the short run, the first-lag-phase economic variable, as well as the second one, the third one, the fourth one, and the second-lag-phase surplus labor force transfer variable, as well as the fifth one, they all give rise to economic short-term fluctuation.

其结论是：中国农村剩余劳动力转移与经济增长之间存在长期的均衡稳定关系；在长期，中国农村剩余劳动力转移与经济增长是正相关的，并且前者是后者的单向格兰杰成因；在短期，滞后一期、二期、三期和四期的经济总量以及滞后二期和五期的剩余劳动力转移总量均造成了经济的短期波动。

During the starting and lowspeed range, the stator windings are shortcircuited and the DFIM system is operated in variable frequency drive mode supplied by rotor side; in highspeed range, the motor works in doublyfed mode, so wide variable speed range can be achieved.

该系统在起动和低速段将定子绕组短路，转子侧采用变频调速运行方式，在中高速段则采用双馈调速运行方式，从而实现了双馈系统在宽转速范围内的平滑调速。

In implementation, a feeler gauge measures the thickness of the just-made sheet metal and sends this signal back to a servo-motor controlling the single variable of traction, the variable to affect the steel last, just before the rollers.

在实施过程中，由一个厚薄规测量刚刚制成的金属板的厚度，然后把信号传回一个伺服电动机以控制牵引力的单一变量——在卷板机之前最后影响钢板的变量。
