"The advantage of our method lies in the smallness, flexibility and precision with which the illuminated area of material can be chosen," Dwyer told nanotechweb.org."Hence, the experimentalist can precisely select the area of material she wants to analyse, and be confident that the surrounding areas are not interfering with her analysis."

对电子显微镜而言，由於物镜工作距离的限制，电子探针与样品常常无法同时被聚焦，因此大部分采用平行式探针的实验都是在探针离焦(out-of-focus)下进行，不幸的是，这种方法会产生如夫奈尔条纹之类多余的图形，因而不如易从绕射图形中精确选出待分析的样品体积。

The exchange field is found to change in an exponential function of 1/|t〓-t〓| in two wedged synthetic antiferromagnets FeMn/Co (t〓=12. 0nm)/Ru (0.7nm)/Co and FeMn/Co /Ru (0.7nm)/Co (t〓=12. 0nm). It has opposite signs and different magnitudes in above two series.

实验上制备了两个系列的楔形样品FeMn／Co／Ru（0.7nm）／Co，其中t〓=12.0nm及t〓变化和t〓=12.0nm及t〓变化，发现交换偏置场与厚度呈〓关系，而且这两系列样品交换场的符号相反。

Investigation of the ballistic propagation of acoustic wave through two almost same sintered samples with face - centered cubic lattices indicates that there is a band gap range respectively in two order quasi - homogeneous media.

研究超声波经过两个烧结样品的行为。两个烧结样品为有序的面心立方结构，它们的结构几乎相同。研究表明：在两个有序的准均匀的介质中分别有一个禁带区域。

Methods: The time of primany fermentation of the negtive fermentation tube which is neither aicd nor gas was prolonged from 1824 h which. Is stipulated by nation criterion detection of coliform bacteria to 3648 h and 358 samples of 7 categories were investigated.

依据国标法检测大肠菌群数，将初发酵培养18~24 h未产酸产气的阴性管样品继续培养至36~48 h，对7类358份样品进行大肠菌群数的检测。

I start my day collecting samples of wine from every fermenter and tank these are sent to the lab for testing and analysis.

开始从每一个发酵罐中收集葡萄酒样品，这些样品被送到实验室中分析。

Objective To establish a method for determination of sorbic acid and benzoic acid in ham by HPLC. Methods Sea sand were added into samples-distill by water in the condition of alkalescence vibratedly-add potassium ferrocyanide and zinc acetate (to deposit protein, faecula,fat.)-determination by HPLC after filtration.

目的 建立火腿肠食品中苯甲酸、山梨酸的高效液相色谱测定方法方法样品加入海砂分散黏稠成块的样品，在碱性条件下用水振荡提取，加入亚铁氰化钾和乙酸锌沉淀蛋白质、淀粉和脂肪等，滤膜过滤进行液相色谱分析。

At first,the as-preparedsample was annealed in an oxidizing atmosphere,the ferromagnetism of the filmdisappeared.

2磁性研究表明：对于不同Tb掺杂量的样品，随Tb掺杂量的增加，样品的每Tb磁矩先增加。
