您要查找的是不是：
- The latter is called the "eigenstate" of the property being measured.A concrete example will be useful here. Let us consider a free particle. 后者也称作被测特性的“特征态”。这里将用一个具体例子。让我们认为一个自由粒子。
- In our free particle example, it turns out that it is impossible to find a wavefunction that is an eigenstate of both position and momentum. 我们以自由粒子为例，找到既有位置又有动量的波函数是不可能产生的。
- That is, one in which a free particle travels in a straight line (or more generally a geodesic) at constant speed, or is at rest. 还是觉得您就是可以自己定义一个惯性系？当然了，拿张纸一画是怎么都可以的哈，就是画着头晕些。
- Various metal or metal the material composing a target is collide with by electrified ion , is brought about the metal atom becoming the free particle deposition surface in Mylar above. 各种金属或金属合成靶材被带电离子撞击，造成金属原子成为自由粒子沉积在上面的聚酯薄膜的表面。
- For example, the free particle in our previous example will usually have a wavefunction that is a wave packet centered around some mean position x0, neither an eigenstate of position nor of momentum. 例如，在早先例子中的三个粒子将通常具有波包中心附近是某些所谓的位置x0的波函数，既不是位置特征值也不是动量特征值。
- Comparing the numerical results with the exact solutions for the free particle case, we showed that the CESE method had excellent results in simulating the variation of the wave function. 数值解与自由粒子之解析解比较显示，时空守恒法模拟变化剧烈的机率分布具有相当精确的结果；
- Reading occupies most of my free time. 阅读占去了我大部分的闲暇时间。
- The Plane Wave Solutions of the Free Particle Dirac Equation 自由粒子狄拉克方程的平面波解
- The crew remained free from scurvy. 那些船员仍然没有患坏血病之虞。
- He's a fervent believer in free speech. 他是言论自由的强烈信仰者。
- She picked up a new magazine with her free hand. 她用空着的一只手拿起一本新杂志。
- Jon sent away for a free almanac. 乔写信去要一份免费赠阅的年历。
- Now that I am free, I can enjoy music for a while. 既然有空，我可以享受一下音乐。
- A free flow of water came from the pipe. 水从管道里通畅地流了出来。
- He closed the deal successfully and was home free. 买卖成交了，他松了一口气。
- He is free with his advice to his pupils. 他直言无隐地向学生提出忠告。
- He is given a free ticket to the exhibition. 有人给他一张免费参观展览的票。
- He was inclined to give them a free hand. 他倾向于放手让他们干。
- She's made free with my records during my absence. 我不在时她擅自用我的磁带。
- We'll eat at whichever restaurant has a free table. 哪个饭馆有空桌我们就在哪儿吃吧。
