我々は理想的な結晶を定義する ― 原子から成る体が格子で取り決めたように、ようである ― 3つの基本的変換ベクトルa,b,cが存在する、{極小の取り決めがあらゆる点で同じものに見える} 特性でどんな点rからでも見られる、{ x,y,zが任意の整数である} 点r'=r+xa+yb+zcから見られる。 ポケトラエコで直翻したらこうなりました。

POINT LATTICES AND THE UNIT CELL Let’s consider the three-dimensional arrangement of points in Fig.15.This arrangement is called a point lattice. If we take any point in the point lattice it has exactly the same number and arrangement of neighbors(i.e.,identical surroundings) as any other point in the lattice. This condition should be fairly obvious considering our description of long-range order in Sec. 2.1 We can also see from Fig. 15 that it is possible to divide the point lattice into much smaller untils such that when these units are stacked in three dimensions they reproduce the point lattice. This small repeating unit is known as the unit cell of the lattice and is shown in Fig.16 A unit cell may be described by the interrelationship between the lengths(a,b,c) of its sides and the interaxial angles (α,β,γ)between them. (α is the angle between the b and c, axes,β is the angle between the a and c axes, and γ is the angle between the a and b axes.)The actual values of a,b,and c, and α,β and γ are not important, but their interrelation is. The lengths are measured from one corner of the cell, which is taken as the origin. These lengths and angles are called the lattice parameters of the unit cell, or sometimes the lattice constants of the cell. But the latter term is not really appropriate because they are not necessarily constants; for example, they can vary with changes in temperature and pressure and with alloying. [Note: We use a,b and c to indicate the axes of the unit cell; a,b and c for the lattice parameters, and a,b and c for the vectors lying along the unit-cell axes.]

Consideration of diffraction from the 100 plane of a cubic material with a body centred lattice shows that X-rays diffracted at the Bragg angle from the 100 planes (the faces of the cube) will be, by definition, in phase. However, halfway between the 100 planes, as a result of the body centring, there is an identical plane of atoms shifted in the x and y directions by (1/2,1/2). この文章を翻訳サイト無しで和訳していただけませんか？

- 線形代数 Theorem 8
例題に The vectors [2], [ 4], [-2] [1] [-1] [ 2] are linearly dependent by Theorem 8, because there are three vectors in the set and there are only two entries in each vector. Notice, however, that none of the vectors is a multiple of one of the other vectors. とあり、この図(二次元で、0からそれぞれの点に線が引かれている)を見ると この例題に関しては納得なのですが、 Theorem 8に関してはどうも納得いきません。 Theorem 8 If a set contains more vectors than there are entries in each vector, then the set is linearly dependent. That is, any set{v1, ..., vp} in R^n is linearly dependent if p>n. p [* * * * *] n[* * * * *] [* * * * *] この説明を読む限り、p(=columnの数)がn(=rowの数)よりも大きい場合はいつでもlinearly dependent(一次で従属している,って言うんですか???)になる、というように解釈しています。それが正しいならば、上の例題の(4,-1)の4が5になったとしても、まだp>n (3>2)なのでlinearly dependentのはずです。しかし、実際にはなりません(よね?)。このTheorem 8は何が言いたいのでしょう? このTheorem 8の矛盾、というか私の勘違いを正して下さい。

Lattice type and systematic absences In indexing the powder patterns it has been assumed that all the possible reflections are observed, that is, scattering from each of the different lattice planes is sufficiently intense to contribute to the diffraction profile. This is normally so for a primitive lattice, but for body centred and face centred lattices restrictions occur on the values that h, k and I may take if the reflections are to have any intensity. This results in certain reflections not being observed in the powder diffraction pattern and these are known as systematic absences. The origin of these absences can be illustrated with regard to Fig.2.3. という文章です。できれば翻訳サイト丸々ってのは控えてほしいです。

In early July 1914, in the aftermath of the assassination of Austro-Hungarian Franz Ferdinand and the immediate likelihood of war between Austria-Hungary and Serbia, Kaiser Wilhelm II and the German government informed the Austro-Hungarian government that Germany would uphold its alliance with Austria-Hungary and defend it from possible Russia intervention if a war between Austria-Hungary and Serbia took place. When Russia enacted a general mobilization, Germany viewed the act as provocative.

It is a patent fact, as certain as anything in mathematics, that whatever exists must have a basis on which to stand, a root from which to grow, a hinge on which to turn, a something which, however subordinate in itself with reference to the complete whole, is the indispensable point of attachment from which the existence of the whole depends. 自分でも訳してみたんですけど、よく分からなくて… お願いします！

- 文中の"any less"について
英長文の過去問を解いているときに疑問に思うことがありましたので、質問させてください。 以下の文中の☆any lessについてお尋ねします。 Even if you feel that atoms themselves are cold, boring, and totally lacking in any interest (a view I would strongly contest), this is not to say that a world composed of atoms should be ☆any less wonderful than one built from some sort of mysterious stuff. (訳)たとえ原子そのものは冷徹で退屈で全くどんな面白みもないと感じられるにせよ(私はそういう観点には強く反対するが)、だからと言って、原子で構成されている世界が何らかの神秘的なもので造られている世界よりも素晴らしさが少しでも劣るはずだということにはならない。 上記の英文中の ...should be ☆any less wonderful... が 「素晴らしさが少しでも劣るはずだ」 となるのが何故なのか解らなくて…。 今まで any less は 「それでもやはり」 という訳になると思っていました。 出題形式は「英文を訳せ」というものだったのですが、"any less"の訳し方に躓いてしまった為ここで質問させていただきました。 何卒、よろしくお願いいたします。
