Fluid power systems and components - 16mm square electrical connector with earth contact - characteristics and requirements 液压流体动力系统和部件. 16平方毫米接地电气连接器.特性和要求
Currently the biosensor is a 25 - millimeter - square plastic chip that has a meandering flow line running through it 目前，这种生物探测仪是一个大小为25平方毫米的塑料芯片，有一个弯曲的流水线从中穿过。
Twenty - five reticules were counted in each specimen and yielded the number of neutrophils in 1 mm2 of the lamina propria ( 0 . 04mm2 x 25 = 1 mm2 ) 在每个样本里面计算25个小格的数目，然后累加起来就得到了固有层里面1平方毫米的中性粒细胞数目。
A unit of retinal illumination , equal to the amount of light that reaches the retina through 1 square millimeter of pupil area from a surface having a brightness of 1 candela per square meter 光度视网膜亮度单位，相当于每平方米有一烛光亮度的表面，通过一平方毫米的瞳孔区域，到达视网膜的光线数量
Connecting devices - electrical copper conductors - safety requirements for screw - type and screwless - type clamping units - particular requirements for clamping units for conductors above 35 mm2 up to 300 mm2 included 连接器件.铜导线.有螺纹式和无螺纹式夹紧装置的安全要求.导体截面为35平方毫米至300平方毫米的夹紧装置的特殊要求
I admired his frugality - rick would sew up the holes in his socks rather than buy new ones , keep cars until they fell apart （ we still have the 1975 camaro he drove on our first date ） and fill up every square millimeter of a note card 我钦佩他的俭朴节约里克宁可自己缝补袜子也不愿买新袜子，汽车要一直用到破旧散架（我们还保存着我们初次约会时他开的那辆卡马罗1975 ） ，并且记事卡上的每个平方毫米都要填满。
The results show that the pyrrole - derivative was successfully electropolymerized on the surface of the electrode . the data estimated by edx results revealed the density of the pyrrole - derivative on the electrode was about several nmol per square milimeter . the 3 - pyrrole - dna also was successfully deposited on the electrode surface by electropolymerization because the edx characterization of polymer shows that the phosphor element was appeared 结果表明， 3 -吡咯甲基-四聚乙二醇单醚可成功地聚合到电极表面，进一步的计算表明，电极表面修饰的3 -吡咯甲基-四聚乙二醇单醚链的密度为每平方毫米几个nmol的数量级，且因聚合方法的不同密度有所差异。
