You choose zx plane, the PRINCIPAL NORMAL is Y The first vector H is defined as follow : H= Z x N. N is the normal vector y in our case. H =-X. The second vector V is defined as V = N x H.

如果你选中zx平面，则主法线方向为y 第一个矢量H如此定义：H=ZxNx为矢量乘积注：遵循右手定则），在我们这个例子中N就是y，H=-X 第二个矢量V定义为V=NxH。

A novel catalytic resonance light scattering method for the determination of traces of formaldehyde in blood plasma was developed. It was based on the fact that potassium bromate reacted with pyronine Y to form association nanoparticles which gave stronger resonance light scattering effect, and formaldehyde can catalyze potassium bromate oxidizing pyronine Y resulting in decreasing of the intensity of resonance light scattering in sulfuric acid.

在稀硫酸介质中，溴酸钾与吡啰红Y能聚集成较大粒径的纳米微粒而使共振光散射增强，而甲醛能催化溴酸钾氧化吡啰红Y而导致体系共振光散射减弱，据此建立了一种灵敏、简单、快速测定血浆中痕量甲醛的新方法。

Once coupled at the filler interface the reactive Y component allows bonding to the polymer matrix by chemical reaction (grafting, addition, substitution) with active groups on the polymer and/or by physicochemical interactions. Y groups are selected to maximize compatibility with particular resin formulations.

一旦在填料界面发生上发生了偶联，反应性部分Y就会通过与聚合物上的活性基团的化学反应或者物理化学作用粘结到聚合物基体上。Y基团可以选择，以优化与特定树脂的相容性。

Application of linear multistep methods to the delay differential equation of the form y′(t =ay +by , t≥0, y =g ,-τ≤t≤0, with a, b∈〓 and b≠a yields the recurrence relation of the form〓, where U〓∈〓 and B∈〓.

In order to gather the information we need about y,according to the model,we regress x against y.

为了在模型中，从x中得到所需要的与y有关的信息，我们用y来回归x。

The top left pixel is considered as the origin of the image with x and y both equal to zero , x increases rightwards across the image and y increases downwards.

左上角的像素被视为图片的原点，此处x和y都等于零，x向右增加贯穿图片，y向下增加。

Methods At first, the relationship of linear or non-linear between dependent X and independent Y in original data can be distinguished by scatter diagram which can be made through Excel software. The scatter diagram of log- arithmic transformation between dependent X and / or independent Y decides which curve to be fitted.

通过利用Excel可绘制散点图的功能，了解原始数据自变量X和因变量Y间的线性与非线性关系，并由自变量X和因变量Y的自然对数转换后的散点图的情况，决定采用何种曲线拟合。

Find the volume of the solid of revolution of the area bounded by the curves y = tan x, y = 2c os x and x = 0

c 求由曲线 y = tan x、y = 2c os x 及 x = 0 所围成的区域绕 x 轴旋转所得旋转体的体积。

We proposed a set of tabulate shim coils to improve the imaging field homogeneity for permanent magnet. By studying the magnetic spherical harmonics and its Taylor expansion, the proposal of designing lower-order radial coils was derived including x, y, xz, xz~2, x~2-y~2 etc. In addition, a novel composite design was presented for the axial coils. By controlling the shim currents of axial coils, different axial magnetic fields can be obtained. This method simplified the design process of axial coils, and made the axial correcting magnetic field more precise.
