A "statement" for discovery purposes is defined by Rule 26(3) to include " a written statement signed or otherwise adopted or approved by the person making it, or a stenographic, mechanical, electrical, or other recording, or a transcription thereof, which is a substantially verbatim recital of an oral statement by the person making it and contemporaneously recorded." This means that if a witness has been interviewed, but nothing tangible was produced, such as a written statement, recording, or transcript, there is no "statement" in existence that can be discovered.

"声明"为宗旨的发现所定义的规则第26条列入"在一份书面声明中签名或以其他方式通过或批准的人，或速记，机械，电气，或其他记录，或转录，因此，这是一个大大的逐字演奏会的口头声明中所作出的人，这和contemporaneously录"，这意味着，如果一个证人已经采访了，但仍然没有具体的制作，如一份书面声明，录音或誊本，还有什么"声明"的存在，可以被发现。

In this thesis, a semi-classical model of the force on an atom is used to describe the motion of a two-level atom interacting with a standing wave laser field. The velocity dependent force and momentum diffusion are derived through optical Bloch equations by using the matrix form of the continued fraction technique. By investigating the dynamic properties of atoms in laser field, we can control and manipulate the mechanical motion of an atom.
