查询词典 Lenard

This article introduces the history of Photoelectric Effect research firstly, including the elaboration of Hertz, Lenard, J.J.

首先介绍光电效应的研究历史，着重阐述了赫兹、勒纳德、汤姆孙、爱因斯坦和密立根等人对光电效应的研究及取得的成

But Lenard never forgave Einstein for discovering and attaching his own name to this law.

直到1905年爱因斯坦发表相对论和光量子理论，才解释了这一现象，后来又被罗伯特·安德鲁·密立根所证实，因为人们把爱因斯坦的名字冠在光量子理论上，莱纳德对爱因斯坦一直耿耿于怀。

Although Lenard at first followed Hertz in believing that the cathode rays were propagated in the ether, he later abandoned this view as a result of the work of Jean Perrin in 1895, Sir J.J.

赫兹因此建议可以用铝薄板将放电管内的空间一分为二，在空间的一部分内，阴极射线由常规的方法产生，而在空间的另一部分，可以在真空的条件下观察阴极射线。

The only difference between these two cells was that in Lenard's cell the electrons were taken from the cathode by light, whereas on the "3-electrode lamp" the cathode is a white-hot filament capable of sending into the vacuum currents of much higher intensity.

在研究过程中，莱纳德还发明了一种光电管，以加速电子和测量它们的能量，这种光电管是三极管最初的雏形，不同之处在于，在莱纳德的光电管中，电子是由阴极光发射的，而三极管中的阴极是白炽丝，可以向真空发射更高强度的电流。

For example,"Yesteryear" goes back to Spock's early years on Vulcan, continuing some explorations from the original series'"Journey to Babel," and offers the familiar voice of Mark Lenard as Sarek.

例如，&&昨日追溯到上火神斯波克的初期，继续在原系列的一些探索'&西游记通天塔&，并提供与绍赖克马克莱纳德熟悉的声音。

Lenard's first work was done in the field of mechanics, when he published a paper on the oscillation of precipitated water drops and allied problems and in 1894 he published the Principles of Mechanics left behind by Hertz.

1892年起任波恩大学的讲师和赫兹教授的助手，1894年被任命为布雷斯劳大学的教授，1895年成为亚琛工业大学的物理学教授，1896年海德堡大学理论物理学教授，1898年为基尔大学教授。

In early November he was repeating an experiment with one of Lenard's tubes in which a thin aluminium window had been added to permit the cathode rays to exit the tube but a cardboard covering was added to protect the aluminium from damage by the strong electrostatic field that is necessary to produce the cathode rays.

在1895年伦琴正在调查外部影响的各类真空管设备，仪器由海因里希赫兹，约翰希托夫，威廉克鲁克斯，尼古拉特斯拉和菲利普冯勒纳德，放电时，是通过他们。 [ 7 ]在11月初他是在重复实验之一勒纳德的管道，其中一个薄铝窗口增加了允许退出阴极射线管，但纸板覆盖增加了保护铝损坏的强烈静电场是必要的生产阴极射线。

Philipp Lenard even claimed that the massenergy equivalence formula of Einstein should be credited to Friedrich Hasenohrl if it had to made an Aryan creation.

菲利普。莱纳德甚至宣称，如果爱因斯坦的质能当量公式确实创造了一个雅利安时代，那也应归功于弗里德里希。哈泽内尔。

In 1932 he was appointed Director of the Institute of Physics at the University of Heidelberg, in succession to Philipp Lenard, becoming in 1934 Director of the Institute of Physics at the Max Planck Institute for Medical Research in that city.

1932年接替菲利普·莱纳德任海德堡大学物理研究所主任，同时开始在马克斯-普朗克学会工作，1934年成为海德堡的马克斯-普朗克医学研究所主任。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
