The thesis first looks back on how the globe develops by shooting at the blank points and grafting the growing points , and then analyzes the macro - background of its development 本文首先回顾了《环球》如何点射空白点、嫁接生长点的发展历程,在此基础上分析了《环球》发展演变的宏观背景。
Double shot 41 point ability , requires deadly aim instant cast 20 sec cooldown " a shot that increases ranged damage by 10 and gives you an extra attack . 双重射击（射击系终极天赋）需要： 5点致死瞄准前置需要： 41点射击系天赋瞬发20秒冷却时间一次造成你的远程伤害加10的射击，同时还会给予你一次额外攻击机会。
" your ranged critical strikes against targets affected by hunters mark increases the damage of melee and ranged attacks against that target by 1 % . lasts 10 sec . " ( up to 5 % 火力集中（ 5点）需要： 25点射击系天赋使你对受猎人印记影响目标的远程致命一击可以增加目标所受到的近战或远程攻击伤害1 % / 2 % / 3 % / 4 % / 5 % ，持续10秒。
In allusion to present point attacking program , calculated the detecting probability for the rocket - assisted torpedo , and analyses effect of some important parameter 着重探讨了采用目标现在点射击方法，对随机机动目标的发现概率仿真计算模型，进行了实际仿真计算，并就一些主要参数对射击效率的影响做了较为深入的分析。
The two point ray tracing is based on the snell theory and the fermat " minimum travel time principle " , which advantages is that it can calculate the accurate ray path from the source to the receiver 两点射线追踪主要是通过snell定理和费马最小时间原理确定激发点和接收点之间精确的射线路径。其优点是能够精确得出反射点的位置。
Comparing the old iteration algorithm , the rapid iteration algorithm is which decomposes binary variable iteration , which include the hit - point range error iteration and hit - point azimuth error iteration , to be two unary iterations 这种方法与惯用迭代方法相比，其优点是将落地点射程偏差和方位角偏差的二元迭代分解成两个一元迭代，这样不仅可大大提高弹道迭代的收敛速度，而且可以满足任何需求的迭代精度指标。
The gauss - ray tracing have the dynamic and geometric character . it can compose the record by calculating the high frequency wave in transverse anisotropic medium , avoiding getting the accurate ray path . it is a very steady and effective method with little calculation time and a good precision 高斯射线束正演包括地震波运动学特征和动力学特征，能有效的计算横向上不均匀介质中高频体波的合成纪录，避开了精确求取两点射线路径，大大减少了计算的时间，同时又具有较高的精度，是一个很稳健有效的方法。
