前面

First, one. analyzes the eigenstates-from reachable sets and seeks the one which the target state belongs to. Then using the Grover iteration to amplify the probability amplitude of the desired eigenstate (the modul square of which is the probability of the corresponding eigenstate that the system will collapse to when it is measured). By measuring, the system will then collapse to the desired eigenstate with a probability of almost unity. Finally, one can use the admissible control to drive the system from the eigenstate to the target state.

该策略的核心思想是对本征态能控的系统，通过分析控制目标态与本征态的关系，寻找给定目标态所属的本征态可达集，然后利用量子非结构化搜索的Grover算法，将任意给定的系统初始态经过一定次数的Grover迭代，放大该本征态所对应的概率幅(概率幅的模方对应测量时波函数塌缩到对应本征态的概率)，然后对迭代后的态进行一次测量操作，使系统以接近1的概率塌缩到所需的本征态(前面分析得到的本征态可达集所对应的本征态)，最后用容许的控制将系统从该本征态控制到期望的目标态。

Two homosexual men: it is strange to have to say it just now because the distinct emphasis of so much that has been said about the movie—in commercial advertising as well as in the adulatory reviews—has been that the story told in Brokeback Mountain is not, in fact, a gay story, but a sweeping romantic epic with "universal" appeal.

前面说到人们因为不得不把他们称为两个同性恋的男人而感到别扭，是因为不论在商业广告还是在那些带有奉承色彩的评论中，都不断反复强调这样一个观点：断背山实际并不是一个同性恋的故事，而是一部有著博爱色彩的广泛适用的浪漫史诗。

He walked in advance of his wife.

Because 忽然 is an adverb, and can only be used before verbs and adjectives.

因为它是副词，只能用在动词和形容词前面。

An equivalent approach to those mentioned above has been taken when considering which aerodrome obstacles should be included in AMDBs.

一个与前面提到的等价的方法已经实施了，当考虑哪些机场障碍物应该包括在 AMDBs 中的时候。

The demands of modern technique have a growing pressure for improvement of radome as a protection in front of antenna, which include the aerodynamical qualities, structural requirements of the airframe and excellent electromagnetic characters.

摘要——现代技术对于作为防护层安装在雷达天线前面的雷达罩提出了很高的要求，除机械特性和气动特性以外，还必须具有良好的电气性能。

I've narrated the affectional course of John and I beforehand. Both of us had married prenuptially. We underwent the suffering of divorce, but we were still yearning for desirable love and confident of lives. We could better understand and encourage each other due to the identical experiences.

在前面我已经讲述了我和John的情感里程，我们在认识之前都曾有过一段婚姻，尽管经历了婚姻失败的痛苦，但我们仍然期待着美好的爱情，仍然对生活充满信心，相同的经历让我们更能互相理解，互相鼓励。

Let's discuss some of the aforementioned ideas.

我们先来讨论一下前面提及的一些观点。
