查询词典 newton

In this paper we propose a new image reconstruction algorithm for electrical impedance tomography-Quasi-Newton algorithm, based on modified Bk. Numerical tests were made to verify the effectiveness of this algorithm.

摘 要 本文提出了一种新的电阻抗成像图像重建算法—基于修正Bk的拟Newton类算法，并通过数值试验验证了该算法的有效性。

No other comparably fertile period for individual scientific accomplishment can be found except during 1665 and 1666, the original annus mirabilis, when Isaac Newton, confined to his country home to escape the plague, started to lay the basis for the calculus, his law of gravitation and his theory of colors.

除1665至1666年，Issac Newton为了躲避瘟疫将自己禁闭在乡下的家中开始构思微积分，引力定律，和光学理论这光辉的一年，历史上还没有任何一个时期个人取得的科学成果可以与其相提并论的。

In chapter II, the local stability of an irreversible Carnot heat engine with a Newton heat transfer law are analyzed.

通过理论分析和数值计算，做了如下工作：第二章分析了牛顿传热规律下不可逆卡诺热机的局域稳定性。

By analysis of the beam element, the governing partial differential equations of transverse vibrations of Timoshenko beam are derived by Newton's second law for the three kinds of boundary conditions.

首先通过对梁微单元体的受力分析，利用牛顿第二定律导出Timoshenko梁横向振动的偏微分控制方程和三种约束边界条件。

Among them Musee de LaMonnaie in Paris ; Antiguo Colegio de San Ildefonso in Mexico City; Palazzo Reale in Milan, Italy; The Helmut Newton Foundation in Berlin: and at the Barbican Museum in London, to this day the most attended show in the museum's history.

他的作品曾在铸币博物馆、圣伊德梵索学院、卡波迪蒙特王宫、牛顿基金会展出，其中，在伦敦巴比肯美术馆的展览直至今天仍是该馆历史上参观人数最多的展览。

Newton 's own motives do not alterthe fact that astronomical observations of which he made considerable use, were a product of Flamsteed's work in the Greenwich Observatory, which was constructed at the command of Charles II for the benefit of the Royal Navy.

牛顿个人的动机并没有改变这样的一种事实，即牛顿大量应用了的天文观测，是英国天文学家弗拉姆斯提德 Flamsteed 在格林威治天文台观测的结果，而格林威治天文台则是为了皇家海军的利益在查尔斯二世的命令下建造的。

The following year, Flamsteed, educated at Cambridge, institutes reliable observations at Greenwich, near London, providing data from which Newton is later able to verify his gravitational theory.

在随后的日子里，弗兰斯蒂德在剑桥接受教育，并在伦敦附近的格林尼治创立了可靠的观测点，提供了后来牛顿验证万有引力所需的数据。

To compute the solution to the nonlinear equation of pressure in the Riemann problem for the pressure grdient equations, the Godunov scheme gives a reasonable approximate value for the exact solution. By using the Newton-Ruphson iteration method and some necessary computation, we get the inter-cell numerical flux directly.
