在100℃和200kPa的条件下，反应aA（g） bB（g）+c C（g）建立平衡后，在不加入任何物质的条件下逐步增大体系的压强（维护温度不变），下表列出的不同压强下反应建立平衡时物质B的浓度。

压强（kPa）2005001000
B的浓度（mol/L）0．040．10．27
      根据表中的数据，回答下列问题：

（1）压强从200kPa增加到500kPa时，平衡        移动（填“正向”或“逆向”或“不”），理由是                                   。

（2）压强从500kPa增加到1000kPa时，平衡        移动（填“正向”或“逆向”或“不”），其原因可能为                                                。

答案

（1）不移动（1分）， 压强增大的倍数与浓度增大的倍数相同   （3分）。

（2）正向（1分）， 浓度增大的倍数比压强增大的倍数要大，加压至1000KPa时C物质变成了非气态物质。（3分）

 Ravi, like many project (1) ,had studied the waterfall model of software development as the primary software life-cycle (2) . He was all set to use it for an upcoming project, his first assignment. However, Ravi found that the waterfall model could not be used because the customer wanted the software delivered in stages, something. that implied that the system had to be delivered and built in (3) and not as (4). The situation in many other projects is not very different. The real world rarely presents a problem in which a standard process, or the process used in a previous project, is the best choice. To be the most suitable, an existing process must be. (5)to the new problem.A development process, even after tailoring, generally cannot handle change requests. To accommodate change requests without losing control of the project, you must supplement the development process with a requirement change management process.
