Tiwi' is the name for the people and the language of Bathurst and Melville Islands, eighty kilometers north east of Darwin.

Introducing the Darwin's method of treating x-ray diffraction in crystals into Bragg diffraction for multilayer structure, a series of analytical expressions are obtained, which can be used to calculate the reflectivity, the Darwin's width, the minimum number of periods and the energy resolution.

将晶体动力学衍射的Darwin理论运用到多层膜对称Bragg反射中，给出了一系列解析表达式，可计算强度比、反射线角宽度、最小周期数及能量分辨率等。

The big breakthrough, of course, was the one Charles Darwin made a century and a half ago.

最大的进展，当然要属Charles Darwin一个半世纪之间的工作。

The non-relativistic energies and wave functions were determined by Rayleigh-Ritz method. The relativistic effects, including the correction to kinetic energy, the electron-electron contact term, and the orbit-orbit interaction, Darwin term, and mass-polarization effect on the energies were calculated by using first-order perturbation theory. In order to obtain a more accurate result for the larger Z system, the quantum-electrodynamics correction should be included. This correction to energy can be evaluated for the valence electron by using a hydrogenic formula with an effective nuclear charge, Z. The ionization potential, the excitation energies and the fine structure split-tings for a lithium-like ion with higher nuclear charge (Z=26) were calculated.

非相对论能量用Rayleigh-Ritz变分法确定，包括动能修正、电子—电子接触项、轨道—轨道相互作用项以及Darwin项的相对论修正和质量极化项由全实加关联波函数的一阶微扰给出，量子电动力学修正由有效核电荷方法和类氢公式计算；给出了较高核电荷(Z=26)类锂体系1s^2nl组态的电离能、激发能和1s^2np组态的精细结构劈裂。

Charles Galton Darwin made this point when he spoke on the centennial of the publication of his grandfather's great book.

Charles Galton Darwin在他祖父的伟大著作百年纪念发言时，就指出这点。

Darwin expanded his studies from sundews to other species, eventually recording his observations and experiments in 1875 in a book, Insectivorous Plants.

Darwin的研究领域慢慢从毛毡苔扩展到其他物种，最终在1875年他将他的观察和实验所得成果记录在了《食虫植物》一书中。

Tracing the development process (i.e. the life history) of vacuum cleaner, we found similarities between product development and evolution trend, such as the theory of "evolve by use and degenerate by no-use" by Lamarck, the theories of mutation, excessive breeding, competition for existence, and survival of the fittest in the Theory of Natural Selection by Darwin and Wallace, as well as the theory of mutation in Neo-Darwinism.

文中经由观察吸尘器诞生后的发展过程，亦即它所经历的生命史中，归纳出它所显现的演变现象有些似乎和演化论有相似之处，例如：Lamarck的用进废退演化现象，Darwin天择说中的变异、过度繁殖、生存竞争、适者生存等，及集合各家说法的Neo-Darwinism中的突变等。

Such a genetic experiment might have astonished and delighted Darwin, who lamented in The Origin that "The laws governing inheritance are quite unknown." Not any longer.

这样的基因实验也许会让Darwin震惊和兴奋，因为他在《物种起源》中哀叹的"主宰遗传的法则完全不可琢磨"已经不是事实了。

Among them: Darwin Sound (along the Beagle Channel by Tierra del Fuego), Mount Darwin in the Andes, and the Northern Territory's own Charles Darwin University and Charles Darwin National Park.

其中包括：达尔文海湾（火地岛旁的贝格尔海峡一带）、安第斯山脉中的达尔文山、和属于北部地区自己的查尔斯·达尔文大学和查尔斯·达尔文国家公园。

Lamarck, whose writings on evolution predated Charles Darwin's, believed that evolution was driven in part by the inheritance of acquired traits.

Lamarck，他比Charles Darwin还要早的提出进化论，认为生物进化是由它们后天获得遗传特征所推动。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
