查询词典 microscopes

Without the improvement in observation tools, many discoveries would be very difficult to verify. From magnifiers, optical microscopes, to radiation discovered at the beginning of the twentieth century

从放大镜、光学显微镜、电子显微镜，到二十世纪初发现了放射线，伴随著加速器的出现，对物质的观察已越来越微观，原子以下的世界逐步揭开。

Historically, critical technical advances made during the mid and late 19th century, including the development of the first high-quality microscopes, the manufacture of synthetic stains, the discovery of effective tissue fixation and embedding techniques, and the development of modern-style microtomes for cutting thin tissue sections produced the first revolutionary shifts in brain tumor classification.

历史上，在19世纪中期及末期出现的重大技术进步，包括第一台高质量显微镜的发展，人造染色剂的制造，有效的组织固定和包埋技术的发明，能够切割较薄组织切片的现代设计切片机的发展等，促成了第一次脑肿瘤分类的革命性变化。

In the present study, we collected cumulus cells oocyte complex from ovaries of two different strain mice. The cumulusenclosed oocytes were cultured for 6 h in MEM supplemented with growth factor and FSH. The meiotic maturation of these oocytes has progressed to pro-metaphse Ⅰ stage and the condensed chromosomes are visible under DIC microscope, metaphase Ⅰ spindle even can be detected under Polscope. The metaphase Ⅰ spindles of oocytes were exchanged under such microscopes. After electric stimuli, 91. 6% and 91. 6% karyoplasts-cytoplasm pairs were fused respectively. The resulting oocytes were cultured further in MEM and over 80% of oocytes released the first polar body. 79% and 77% of oocytes formed two pronuclei after in vitro fertilization and the embryos were cultured in KSOM supplemented with amino acids. Over 60% of embryos developed to blastocyst stage.

在本研究中我们在取得两种不同品系小鼠的卵丘卵母细胞复合体后，先将卵丘卵母细胞复合体置于含有多种生长因子和激素的MEM培养液中培养6小时，此时卵母细胞已进入第一次减数分裂的前中期，并且在DIC倒置显微镜下可以看到浓缩的染色体，用Polscope可以发现明显的纺锤体，借助这种显微镜通过显微操作将两种不同品系小鼠来源的卵母细胞的MI纺锤体进行互换，经过三次直流电脉冲作用后，分别有91.6％的胞质—MI核质体对融合，经过进一步的培养后，超过80％的重组卵母细胞排出第一极体，体外受精后分别有79％和77％的重组卵形成双原核，受精后的胚胎在KSOM胚胎培养液中体外培养4天后，超过60％的胚胎发育至囊胚。

Friedrich Krner, mechanic and supplier to the court (who has been making simple microscopes since the early forties); attendance of lectures at the Jena University (mathematics, experimental physics, anthropology, mineralogy, optics); journeyman's travels for several years; practicals at Professor Schleiden's physiological institute in Jena.

Krner 博士的学徒（ Krner 博士给宫廷提供维修及其他服务，在40年代早期开始从事显微镜制造）。

There, white-coated technicians pore over microscopes amid an array of incubator-like machines, steel racks of petri dishes, and jiggling, vaguely robotic mixers, all part of a biotechnological assembly line that by this spring will be producing tens of thousands of cloned embryo a day.

那里，身穿白色工作服的技术人员俯身于显微镜上专注地工作着。他们置身于一排类似恒温箱的仪器、放满皮氏培养皿的钢架以及轻微颤动的自动资料器的中间。所有这些组成了生物技术生产流水线，它今年春天就会每天制造出上万个克隆胚胎。

Employ, soft x ray microscopes be to not happen ago match the highest resolution

射线显微镜永远比不上自动显微镜估计具有的很高分辨力。

Employ, soft x ray microscopes will not happen before match the highest resolution

射线显微镜永远比不上电子显微镜估计具有的最高分辨力。

With the advent of nano era, atomic force microscopes have been widely adopted as the major tool for analyzing or discovering new phenomena in research labs. However, it is clear that the environmental conditions like vibrations, changes in temperatures, noises etc., as well as post signal processing, can always affect the images of an AFM.

中文摘要随著奈米科技的进步，利用原子力显微仪做为主要的研究工具，来发现或验证新的物理及化学现象，成为不可避免的趋势，然而，对於 AFM 本身的制作开发，其周边环境因素的控制（如振动、温度、干扰杂讯等）、操作介面及讯号撷取后之处理，甚至探针的制作研究等，都是影响 AFM显像品质的重要影响因子。
