这句话怎么翻译啊.我真的没分了

潜打印
Although the word latent means hidden or invisible,in modern usage for forensic science the term latent prints means any chance of accidental impression left by friction ridge skin on a surface,regardless of whether it is visible or invisible at the time of deposition.虽然这个词潜在的或无形的手段隐藏在法医学长期潜伏版画现代用法,是指：通过摩擦脊皮肤表面留下的印象意外的机会,不论它是可见或不可见的沉积时间.
Electronic,chemical and physical processing techniques permit visualization of invisible latent print residue whether they are from natural secretions of the eccrine glands present on friction ridge skin (which produce palmar sweat,consisting primarily of water with various salts and organic compounds in solution),or whether the impression is in a contaminant such as motor oil,blood,paint,ink,etc.电子,化学和物理处理技术,允许残留的可视化无形的潜在打印是否从山脊上的摩擦皮肤（手掌出汗而产生,主要是与各种盐溶液中的有机物和水组成）目前汗腺腺体分泌物自然,或是否在污染物的印象是,如机油,血液,油漆,油墨等
Latent prints may exhibit only a small portion of the surface of the finger and may be smudged,distorted,overlapping,or any combination,depending on how they were deposited.潜伏打印可能会出现只有手指的表面的一小部分,可能是污迹,扭曲,重叠,或任意组合,这取决于他们如何存放.
For these reasons,latent prints are an “inevitable source of error in making comparisons,” as they generally “contain less clarity,less content,and less undistorted information than a fingerprint taken under controlled conditions,and much,much less detail compared to the actual patterns of ridges and grooves of a finger.”由于这些原因,潜在的版画是“不可避免的误差来源进行比较,”因为他们一般“含有较少的清晰,内容较少,而较少失真比在受控条件下采取了指纹信息,以及更多,更详细的比较,脊和沟槽的手指实际模式.
