The author also makes a distinction between the role of algebra in analytical geometry and that in Descartes'Geometry.

澄清了以往认为代数在解析几何中的作用与在笛卡儿《几何学》中的作用相一致的观点。

But, Einstein criticized Kant repeatedly for his apriorism, and didn't agree that human create laws of Nature. Einstein denied that geometry propositions are "synthetical judgments a priori" as Kant called.

但爱因斯坦不赞同康德的先验论，反对康德人为自然立法的观点，并否认几何学是康德所谓的"先天综合判断"。

Bond and angle types are assigned based on (1) atom types,(2) bond lengths or bond angles in the QM optimised geometry and (3) matching force constants derived from the Hessian matrix.

键和键角类型标记，依据（1）原子类型（2）量子优化几何学中的键长或者键角（3）源于 Hessian 矩阵的合适的力常数。

Some six decades later when Kepler tackled the motion of Mars, he proposed a number of geometric models, checking his results against the position of the planet as recorded by his boss, Tycho Brahe, a Danish astronomer.

在60年后，开普勒在研究火星的运行诡计时，他假设了大量的几何学上的模型。

In addition, depending on the method of numerical simulation and theoretical analyses, some kinematic and geometric features of 0° involute—enveloping worm gear drive, such as meshing surface, first—type limit, second —type limit, worm surface, the numerical representation of contact line and bearing contact, are systematically studied. These relevant conclusions provide an important basis for the design and manufacture of new type worm gear set. As we predict, the method of numerical simulation has special effect in solving the question of complex conjugate surface.

综合利用仿真方法与解析手段，对0°渐开线包络蜗杆传动的啮合面、一类界限、蜗杆齿面构成、仿真接触线及仿真接触域等运动几何学特性进行了系统研究，有关结论为此种新型蜗杆副的设计与加工提供了重要基础，并且显示出数字仿真方法在研究复杂共轭曲面问题时所具有的特殊功效。

Methods:According to the standard of Borden Ways and Seze Ways to measure the regular cervical and lumbar curvature, then use the sectorial area formula of mathematics geometry to calculate the regular curvature arch form area of cervical and lumbar.

按Borden法和Seze法的标准，测出正常颈曲和腰曲，然后按数学几何学扇形面积计算公式，即S弓形，计算出正常的颈曲、腰曲的弓形面积，并统计正常颈曲126例，正常腰曲114例，经统计学处理得出均值和标准差。

According to the structure and motion characteristics of the spherical offset mono-cone bit, compound cylindrical coordinates were set up, and basic geometric equations and the conditions of teeth to penetrate rock for the bit were presented.

针对偏心单牙轮钻头的结构和运动特点，利用复合圆柱坐标系统的基本原理，建立了偏心单牙轮钻头几何学基本方程和牙齿对岩石的吃入条件。

Distance and dihedral angle constraints are used in distance-geometry and molecular dynamics computations to calculate and refine these structures.

他们将距离和二面角的约束效应运用在距离几何学和分子动力学的计算中使其对分子结构的测定更为精确。

All divalent zinc triad metal ions are d10,leading to weak secondary bonds and widely variable geometric preferences...

全部二价的锌三人小团伙金属离子是d10，导致弱的第二契约和广泛易变的几何学偏爱。。。

In the third century B.C. in Alexandria, the Greek scholar Eratosthenes relied on both geometry and reports of the sun's annual appearance almost directly over Aswan to calculate Earth's circumference, arriving at an estimate close to the actual distance.

在亚历山大公元前第三世纪，希腊学者 Eratosthenes 依据几何学和每年太阳出现在阿斯旺差不多正上方的记录来计算地球的周长，估计的数字接近实际距离。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
