This paper establishes mathematical models of unsteady and Non-Darcy low speed flow through the porous media and the double porous medium, and has obtained their solutions in an infinite reservoir through Laplace transformation, and their long time asymptotic solutions has been worked out, solutions on a bounded reservoir has also obtained through finite integral transformation and Laplace transformation.

从现场上各种水淹的实际资料来看，同一水动力的非均质油层系统中，渗透率相对较高的部分水洗之后，渗透率相对较低部分的油层却可以原封不动。而且，其渗透率可达达西级，含油饱和度可达80％以上。相对流动比(即同一水动力的非均质油层系统中，小层平均渗透率的最大值与其中不流动部分的小层平均渗透率的最大值相比)的比值在各种油层的生产实例中十分相近。一般的分布范围为3—7，常见的为4—6。实验室结果和生产实践基本相同。简单的注水和压裂对这一比值几乎无影响。

在对紧固件承受横向冲击或交变载荷时进行动力学分析的基础上，对紧固件横向振动试验台在油源功率受限的条件下的液压动力机构的设计问题，提出了有效的解决方案，即用相对较大的动力机构的功率配置来降低系统对油源功率的要求，同时用双阀并联的方法克服了大流量伺服阀频宽较低对系统频宽的影

This paper briefly introduces the current development of supercavitating torpedoes in the world,and explains some confusable terms,including cavity,supercavitation, natural supercavitation ,air supercavitation and cavity number.

在简要回顾各国超空泡鱼雷发展概况的基础上，解释了几个易混淆的与空泡有关的新术语(空泡、超空泡、自然超空泡、通气超空泡和空泡数)，分析了超空泡的形成机理和特点，详细阐述超空泡鱼雷在总体结构和性能、动力推进、控制系统和弹道形式等方面的技术特点，概括超空泡鱼雷与普通鱼雷在结构外形、流体动力布局、系统组成和工作特性等方面的不同之处。

The machine flies with more power in that it bogs very little compared to the flybar 700, especially in elevator, aileron tick tocks and big ben type maneuvers. Less attention to collective management is necessary with this additional power and you can focus more attention to you cyclic inputs. The cyclic is sure and powerful with no bobble at the stops in the tic tocs.

700搭配无平衡翼系统飞行时源源不断的动力，是传统系统无法比拟达到的，特别是在升降前后、副翼左右钟摆及十二点钟摆这类的动作，这额外的动力可以让你更专注在控制十字盘的动作上，少些注意力在集体螺距的控制，在执行钟摆动作的顿点时，十字盘的动作是准确、有力的，而且无抖动。
