specimens

• Values were derived from the duplicate 12 x 3-in. specimen compliances.
  该值是由成对的12英寸X3英寸试样的柔度得来的。
• The electrons forming the image must be emitted by the specimen to be observed .
  构成物象的电子必须由要观察的样品发射。
• The elongation at break is increased and the specimen may neck before fracture .
  断裂伸长增加，试验出现细颈状，然后断裂。
• Duplicate 12-in. long specimens were calibrated with an 8-in. gage length .
  两个完全相同的12英寸的标本用8英寸标距来标定。
• A specimen which is much thicker than the penetration depth decays exponentially .
  一个比穿深透度厚得多的样品，按指数律衰减。
• The biologist stained the specimen before looking at it through the microscope .
  那位生物学家先把标本染色，然后再通过显微镜进行观察。
• The specimen must be adequately grounded to prevent the development of the high voltages .
  为了防止这种高压的发生，试件必须妥善接地。
• The zero point of the density scale is defined by having no specimen in the densitometer .
  定义密度计内没有样品时的密度为密度尺标的零点。
• After setting, the surfaces of the specimens are ground down using carborundum and alumina .
  凝固之后，样品表面连续用金钢砂或氧化铝磨平。
• The compliance-calibration specimen has a slot of finite-tip radius in place of a crack .
  柔度算定试样是用一个有限端部半径的槽来代替裂纹。
