使不变

Complicating this issue is that either magnetic or geographic pole is not static.

使这个问题复杂化的是磁极或地极中任何一个位置都不是静止不变的。

The illiberality of parents, in allowance towards their children, is an harmful error; makes them base; acquaints them with shifts; makes them sort with mean company; and makes them surfeit more when they come to plenty

在子女小时不应对他们过于苛吝。否则会使他们变得卑贱，甚至投机取巧，以至堕入下流，即使后来有了财富时也不会正当利用。到中国译典经典版本中查找关于surfeit的最新解释和例句。。。。

If the ratio of Cu 2+ to In 3+ is constant, the total concentration of ions showed inappreciable influence on film morphology. The result shows that lauryl sodium sulfate and sodium benzenesulfinate as ideal additives can make the films more flat and smooth.

此外， 在镀液离子低浓度范围内，及Cu/In离子浓度比不变的前提下，镀液中金属离子总浓度的改变不会影响镀层的成分和形貌；十二烷基硫酸钠和苯亚磺酸钠可作为理想的辅助添加剂，能改善薄膜形貌，使其表面均匀、规整。

The advantages of this new method are:(1) The field conductivity distribution function is fitter the actual condition than tradition methods:(2) On the condition of triangle elements cut of field, making the calculation speed increase in large degree than tradition methods.

与单元电导率重建算法相比，节点电导率重建算法的优点有：(1)使场域电导率分布函数更符合实际情况，克服了传统算法中对电导率作离散化处理的缺陷；(2)当场域采用三角形单元剖分方式时，在场域的剖分密度保持不变的情况下，可以大大提高重建计算的速度；(3)在场域采用三角形单元剖分方式时，场域的剖分密度可以比以前加大一倍，在不降低重建计算速度的前提下，可以改善重建计算的精度；(4)由于重建的是所有节点的电导率，避免了先前单元电导率重建图像中"阶梯"状边缘和"锯齿"状边缘的出现，明显地改善了图像的视觉效果。

Sure enough, banks are making the most of today's conditions: Credit Suisse, for instance, is structuring mortgage securities that are unrated by credit-rating agencies; it and others have begun securitising life-insurance policies that the old and infirm sell for cash.

标准化的推动了场外衍生工具合约，例如，可以，如果采取太远，让投资者试图对冲钝器特定风险，使系统变得更不安全，而不是更多。

Not consciously, I am right here, had a nostalgic feeling of dismay, that the pure smell, that wonderful voice, and that the mangosteen up tall and straight, even made me get that clear again calm.

在不自觉中，我对这里产生了眷恋不舍之情，那纯洁的气味，那美妙的声音，那挺拔向上的山竹，竟然使我变得即清醒又冷静。

In this paper,Restricted Minimum Disturbance Map based scheme of attitude control is presented to keep the attitude of the base fixed during the movement of the manipulator via planning motion trajectory of the end-effector of manipulator without using reaction wheel or reaction thruster.

这种方案不使用反作用轮或反作用喷气装置，而通过规划机械手末端的运动轨迹，使机器人的本体姿态在机械手动作过程中基本保持不变。

Based on the analysis of current oscillation region of stable electric fielddomains in I-V curve,it is shown that when the applied bias voltage is changedwithin positive slope regions of I-V curve,the domain boundary between the high-and low-electric field domains does not moved,and the size of electic fielddomains regions is also not altered,while the electric filed strengths are adjusted tokeep the current conservation.

通过对稳态电场畴情况下I-V曲线中电流振荡区域的分析，证明当外加偏压在正微分电导区变动时，超晶格的高低电场畴之间的畴边界不发生移动，畴的大小不变，只是相应的电场强度做些调整以使电流守恒成立。

The pipelined CORDIC architecture is very suitable for FFT butterfly operation because of its high throughput and regularity, but it will consume lots of resources,this article presents an improved architecture of CORDIC pipeline,starting with the property that the FFT rotary factor is fixed but not arbitrary,and according to the mapping between the basic rotational angle of CORDIC and scale factor and the rule for transform among the scale factors.On the condition that the velocity of FFT butterfly operati...

CORDIC流水线结构因其高吞吐率及规整性，而很适合于FFT蝶形运算，但其缺点是耗资源多，本文从FFT中旋转因子固定不任意的特点出发，根据CORDIC基本旋转角度与缩放因子的对应关系和缩放因子之间的转换规律，对CORDIC流水线结构进行了改进，在蝶形运算速度不变的情况下，进一步减少所耗资源，在字长为16位的FFT中，每个旋转因子可用25位的控制序列来替代，从而使每个旋转因子的存储空间由32位减少到25位。

The ancients, he said, held that Tethys the God of the ocean had made the world from water; Anaximenes and Diogenes made air prior to water, while Hippasus of Metapontium and Heraclitus of Ephesus said that fire was the ultimate substance of the world, and Empedocles added a fourth, earth, and said that these four elements were together the substance of reality; Anaxagoras of Clazomenae, said that the principles are infinite in number, and are not in any sense generated or destroyed, but remain eternally.

他说，古代人相信世界是海神Tethys用水造的；阿那克西米尼和第欧根尼使气先于水，而Metapontium的喜帕索斯和埃菲索斯的赫拉克利特说火是世界的最初substance，而恩培多克勒添加了第四个，土，并说这四个元素一起是现实的substance；Clazomenae的阿那克萨哥拉，说本原在数上是无限的，且在任何意义上不被生成或毁灭，而永远保持不变。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
