现代显微学制片中的普通切片机,(此种切片机可切1微米以下切片,其他型号的切片机也可用手工把刻度指示到1微米以下,如在0.5微米处切一片,转向1微米处切第二片,再退到0.5微米处切第三片,每片等于0.5微米。其余1微米以下切片可类推,本文指的是1960型Jung切片机由于齿輪系摩擦式推进装置的,可以在1微米以任何厚度上切出1微米以下的切片,不必用手工操作。)已能切出0.25微米的菲薄切片,切片上不得有丝毫的折皺和外来异物,否则在放大1000倍以上时,那些人为的缺陷可使组织本身的形态改变,
Common microtome in modern slicing machine, (slicer can be sliced below 1 micron slice, other models of slicing machine can also be used to indicate the scale below 1 micron, such as cutting a 0.5 micron, turn 1 Cut the second film, then retreated to 0.5 microns cut a third film, each piece is equal to 0.5 microns.The remaining 1 micron slice can be analogy, this article refers to the 1960 Jung slicing machine due to the gear friction friction propulsion device, Slices up to 1 micron in thickness can be cut at any thickness of 1 micron without the need for manual handling.) Thin slices of 0.25 micron can be cut without the slightest wrinkles and foreign particles on the cut, or at 1000X magnification , Those artificial defects can change the form of the organization itself,
