To oversee all the details yourself in person; to be at once pilot and captain, and owner and underwriter; to buy and sell and keep the accounts; to read every letter received, and write or read every letter sent; to superintend the discharge of imports night and day; to be upon many parts of the coast almost at the same time -- often the richest freight will be discharged upon a Jersey shore;-- to be your own telegraph, unweariedly sweeping the horizon, speaking all passing vessels bound coastwise; to keep up a steady despatch of commodities, for the supply of such a distant and exorbitant market; to keep yourself informed of the state of the markets, prospects of war and peace everywhere, and anticipate the tendencies of trade and civilization -- taking advantage of the results of all exploring expeditions, using new passages and all improvements in navigation;-- charts to be studied, the position of reefs and new lights and buoys to be ascertained, and ever, and ever, the logarithmic tables to be corrected, for by the error of some calculator the vessel often splits upon a rock that should have reached a friendly pier -- there is the untold fate of La Perouse;-- universal science to be kept pace with, studying the lives of all great discoverers and navigators, great adventurers and merchants, from Hanno and the Phoenicians down to our day; in fine, account of stock to be taken from time to time, to know how you stand.

亲自照顾一切大小事务；兼任领航员与船长，业主与保险商；买进卖出又记账；收到的信件每封都读过，发出的信件每封都亲自撰写或审阅；日夜监督进口货的卸落；几乎在海岸上的许多地方，你都同时出现了似的；——那装货最多的船总是在泽西岸上卸落的；——自己还兼电报员，不知疲倦地发通讯到远方去，和所有驰向海岸的船只联络；稳当地售出货物，供给远方的一个无餍足的市场，既要熟悉行情，你还要明了各处的战争与和平的情况，预测贸易和文明的趋向；——利用所有探险的成果，走最新的航道，利用一切航海技术上的进步；——再要研究海图，确定珊瑚礁和新的灯塔、浮标的位置，而航海图表是永远地改而又改，因为若计算上有了一点错误，船只会冲撞在一块岩石上而至于粉碎的，不然它早该到达了一个友好的码头了——，此外，还有拉·贝鲁斯的未知的命运；——还得步步跟上宇宙科学，要研究一切伟大的发现者、航海家、探险家和商人，从迦太探险家饭能和腓尼基人直到现在所有这些人的一生，最后，时刻要记录栈房中的货物，你才知道自己处于什么位置上。

Statistic analysis result shows that the time step is the most important influence factor of simulation precision, and there is relation between simulation error and the setup value of restitution coefficient which the greater the setup value is, the less the simulation error is. Although there is no effect to the total contact time in the course of collision, the value of the time step decides the total contact step, and there is a logarithmic linear correlativity between them.

统计分析结果表明：计算时步是影响模拟精度最重要的因素；模拟误差还同恢复系数的设定值有关，设定值越大，模拟误差就越小；计算时步的大小虽然对碰撞过程的总接触时间影响不大，但是却决定了碰撞过程的总接触时步数，二者之间存在对数线性相关关系
