查询词典 ram bow

First, the effects of magnetic RAM relaxation time and the rise-time of incident pulse signal on reflection signal are discussed, the relationship between the rise-time of incident pulse and relaxation time based on the energy of reflection signal is revealed. Then, the effects of magnetic hysteric, susceptibilities and saturation upon reflection signal are analyzed, the results reveal the reflection of RAM target and UWB signal design. In the meantime, dielectric relaxation time effect about dielectric RAM target is analyzed simply, and the effects of relaxation time and the width of incident pulse upon reflection signal are probed. Finally, a few RAM targets are measured in the chamber using the impulse radar experiment system which is developed by the team of anti-stealth impulse radar on Department of Electrical Engineering, National University of Defense Technology. The experimental results show the similarity of the rule of echos with the theory. From the compared results of different tagets, we concluded, compared with 15% wideband sinusoidal signal, the impulse signal has increased 10～12dB energy from the same loaded RAM target; this, in turn, shows the nonlinear effects of RAM to the echoes, and the potentiality of the impulse signal to RAM targets.

首先分析了磁性RAM的弛豫时间及入射脉冲信号的上升时间对反射信号的影响，从反射信号能量角度出发，给出了入射脉冲上升时间与弛豫时间的关系；接着分析了磁性RAM的磁滞特性、磁化率及磁化强度对反射信号的影响，给出了RAM目标辐射和有关UWB信号设计的一般性结论；其次，对介电RAM的弛豫时间效应作了简单的分析，探讨了介电弛豫时间及入射脉冲宽度对反射信号的影响；最后利用国防科技大学电子技术系&反隐身冲激雷达技术研究组&研制的冲激雷达实验系统，在微波暗室中对几种不同的RAM目标进行了测量，结果表明：其反射波形的基本规律与上述理论分析相一致；从各种不同目标回波的能量对比结果得出，涂覆RAM目标对冲激信号的吸收比15％带宽的正弦信号要小10～12dB，证实了RAM的非线性效应对回波的影响，也证实了冲激信号反隐身的潜力。

Holding the bow is like a teeterboard supported by thumb as the pivot and the cooperated forcing of forefinger and little finger produces a moment M. The "P-x-M Line Method" shows when playing a down bow, M increases with x and gradually changes its direction and this process is determined by P, the gravity and barycenter of bow. The "P-x-F Plane Method" shows that the most force-saving bowing path should locate in the lower part of this plane. The analyses of "Helmholtz Motion" and "Schelleng Diagram" indicate P and its range is in direct ratio with volume, velocity of bow, the approaching degree of the bow to the bridge and has some relationship with the quality of string and bow.

国内近期出现了用物理模型来研究小提琴运弓问题的尝试本文第一部分首先指出握弓类似于一个以***(F3)为支点的跷跷板，主要以食指(F1)和小指(F2)的施力配合，产生握弓力矩M；随后用"P-x-M直线法"证实：演奏下弓是M随的***而逐渐增大并转换方向的***，此***取决于P、弓的重力和重心；并首创"P-x-F平面法"，在x，F1，F2空间中证实：省力的运弓路径应在该平面中处于较低的位置第二部分通过分析"赫尔姆霍茨运动"和"Schelleng图表"指出：P及其变化范围和音量、弓速、弓与琴码的接近程度成正比，并与琴弦和弓自身的性质有关

The effect from transverse webs and frames and the effect from collision velocity on ship bow collision properties are also studied in this paper. 7. The idea of buffer bow is put forward from aspects of the overall situation of environmental protection and reducing the damage of struck shipside caused by striking bow. The influence of curvature of bow shape on mode of distortion, collision force, collision force density and energy absorption of bulbous bow is described detailedly through a series of collision numerical simulation for bulbous bows that have different curvature.

发现横向框架对于船艏结构的变形形态，碰撞力及能量吸收都有一定的影响，在进行碰撞分析时不能忽略，在较低的速度范围内碰撞速度对碰撞力及能量吸收没有太大影响，所以可以从较高速度撞击后得到的能量吸收曲线中得到较低速的碰撞能量吸收曲线，从而可以得到低速碰撞时的撞深，然后通过这个撞深在较高速碰撞的碰撞力曲线中可以获得低速碰撞的碰撞力曲线。
