零

In such a medium, the direction of the Poynting vector monochromatic plane wave is antiparallel to that of its phase velocity. Because of that, DNG displays some unusual electromagnetic properties such as backward-wave effect, negative refractive effect, perfect lens and a limit situation, zero index of refraction materials.

在这种材料中，单色均匀平面波的相速方向和坡印亭矢量方向是相反的，因此使双负材料表现出一系列反常的电磁特性如：回波效应、负折射效应、完美透镜效应和一种极限情况即零折射率材料等。

A few obvious features help us to walk efficiently: we move our arms and legs in antiphase, thus keeping the total angular momentum more or less zero.

几个明显的特点使我们走得很有效率：我们的胳膊与腿逆相位摆动，这样使总的角动量大致为零。

I don't think there is any such thing as less than nothing.

我想，不存在少于零的那样东西。

We calculate the field distribution near focus of an aplanatic system for incident ASPBs with different polarization orders and initial azimuthal angles, and based on the simulation results, we find some unique focusing properties of the beams, such as ever on-axis energy null, strong longitudinal field, and flowerlike intensity distribution at focus.

计算了不同偏振级次和偏振初始角的轴对称偏振光束当入射到无球差系统时在焦点附近的场分布，通过这些模拟结果，发现了该光束一些独特的聚焦特性，例如光轴强度始终为零、具有较强的轴向光场以及在焦点附近场呈现花瓣状分布等。

Not only in the education system in Tianjin Nankai. Establish a "zaro appel" model, within the transportation industry for the design of the thousands of professional and technical personnel. Formed a comprehensive, systematic employment system.

不仅在天津市南开教育系统内树立了"零投诉"的典范，为设计业界内输送了上万名的专业技术人才，形成了一套完善的、系统的就业体系。

Some days I might go a little overboard with all this peanut butter consumption: a piece of toast at breakfast, smeared thickly with homemade peanut butter and a bit of honey;baked tofu marinated in a lemony peanut sauce for lunch; a crisp apple spread with peanut butter for an afternoon snack.

从零基础开始制作花生酱，比起买了一罐，显然不仅仅是花费更多的时间，从另一方面它可以更加经济实惠，特别是如果你买的是散装花生的话。也可用其他坚果取代花生-如核桃或杏仁-甚至和花生混在一起成为一个更为复杂的风味也是可以的。

In addition, the parameters sum of conditional heteroscedasticiity function tend to zero as aggregation level m approach to infinity, and conditional heteroscedasticity almost disappears.

最后，随著加总水准m愈大时，条件变异数方程式的参数加总趋近於零而条件异质性也跟著消失。

In this paper we use pointwise modulus of smoothness to study approximation direct theorem and equivalent theorem for some linear operators and quasi-interpolant operators; Using pointwise modulus we discuss the strong converse inequality on K-functional; and using a modified weighted K-functional and weighted modulus of smoothness we study approximation with Jacobi weight on operator with non-zero first order moments.

本文利用点态光滑模ω_~(2r)来研究某些线性算子及逆中插式逼近正定理和等价定理；利用点态光滑模讨论其关于K-泛函的强逆不等式；同时利用一种改变的带权K-泛函和带权光滑模研究一阶矩不为零的算子的点态带Jacobi权逼近。

It seems the inspiration came from the Arabian Nights.

看来它的灵感是来自于《一千零一夜》。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
