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。

Collision – Unknown to both me and Brother Laz, but this boolean is related to the previous one, many missiles that have no "physical collision" but still perform a collision event will have this set to 1.

Collision –我和Brother Laz都不清楚这列是什么用。，但这布尔型关系到前一列，很多投射物没有&物理碰撞&但时依然旅行碰撞事件，在这里设置为1。

Compared with existing methods, FCPF have the following characteristics:①Can improve precision of collision time and collision points but no more collision detection is needed;②Take into account of not only movement but also rotation of collided virtual objects;③Can find collision time and collision points among convex and/or concave polyhedrons.

与已有的一些方法相比，该方法具有以下特点：①不需要通过增加碰撞检测次数来提高碰撞时刻与碰撞点的求解精度，因而减少了碰撞检测的系统开销，提高了基于物理特性进行碰撞响应的实时性。

Of course, all the standard safety components are standard - BMW is proud of the high ratings its cars earn in U.S. and European crash tests - including six air bags, ABS, belt pretensioners, seat belts mounted to the seats, and driver's pedals that move back automatically in the event of a frontal collision.

当然，所有的标准组件的安全标准-宝马骄傲的高收视率，其汽车收入在美国和欧洲的碰撞测试-包括六个安全气囊， ABS树脂，预拉装置，安装安全带的座位，和司机的踏板是搬回自动在发生正面collision。

Have made their research programs to develop the safety guarantee technology of Ⅳ and have already achieved great progress, for example the adaptive cruise control or intelligent cruise control , collision avoidance system and platoon etc. In China, most of the research work on Ⅳ is focused on the autonomous navigation technolgy.

美、欧、日等西方发达国家已经抢先一步，在智能车辆安全保障以及汽车安全辅助驾驶技术的研究方面相继投入大量人力、物力，取得了许多有价值的研究成果，如自适应巡航控制(Adaptive CruiseControl，ACC)或智能巡航控制(Intelligent Cruise Control，ICC)系统、防碰撞系统(Collision Avoidance System，CAS)以及汽车队列等，并产生了明显的社会和经济效益。

Based on probability theory, a method for describing and calculating the collision probability between rendezvous and docking vehicle and debris is presented, and the method involves quantitatively analyzing the collision probability using quasi maximum instantaneous collision probability and total collision probability.

In our approach, a two-block message is still needed to produce a collision, the first block being only one MSB different while the second block remains the same.

本文所提出的1-MSB输入差分碰撞技术中，仍然采用两个消息分组，但其中第一个分组仅第九个消息字的最高位需要差分，而第二个消息分组可无需差分，即第二个消息分组碰撞是一个伪碰撞（Pseudo-collision）。
