对角线的

The details as follow: 1.Based on rules about form error in GB, mathematical models of form error are established including straightness error on the base of minimizing zone method、least-squares method and two dots linked method ; flatness error based on minimizing zone method、lease-squares method、diagonal line and three dots method; circularity and cylindricity error based on minimizing zone method、lease-squares method、minimum circumscribed circle and maximum inscribed circle.

具体内容如下：根据国标中形状误差的相关规定建立了各种要素评定方法的数学模型包括：直线度的最小区域法、最小二乘法、两端点连线法；平面度的最小二乘法、最小区域法、对角线法、三远点法；圆度和圆柱度的最小区域法、最小二乘法、最小外接圆法、最大内切圆法。

According to the definition of the minimum zone method, the mathematical model is presented for evaluating flatness error and establishing datum plane equation.

分析了常用的近似评定法(三点法、对角线法、最小二乘法等)存在的局限性，根据最小区域法的定义，给出了基准平面方程及平面度误差评定目标函数数学模型的建立方法，并举例说明了采用Matlab进行平面度误差的计算。

This increase in lumen output is useful if you wish to use a screen larger than 100 diagonal, or if you have some ambient light in your projection environment that cannot be removed.

流明输出，这在增加有用的，如果你想使用大于100的屏幕对角线，或者如果你有你的投影测量周围环境的光，无法删除。

Therefore, the early use of low-permeability reservoir development Diamond Anti-9:00 Well, diamond crack parallel to the main diagonal directions along the crack edge wells to increase water efficiency by the degree of widening further suppress the injection wells, well away from the row Kadoi premature flooded, and the overall benefit of fracturing; in the latter part of the diamond-shaped anti-9:00 Well Well turn the corner to form staggered rows like water injection means, thereby maintaining a high production rate and phase out the extent of mining.

因此，低渗透油藏开发初期使用菱形反九点井网，菱形主对角线平行裂缝方向，沿裂缝注水增加边井受效程度，拉大的井距又可抑制注水井排的角井过早水淹，且利于整体压裂改造；中后期将菱形反九点井网的角井转注形成交错排状注水方式，从而保持较高的采油速度和阶段采出程度。

A general mathematic model of lifting subsystem and hydraulic balancing subsystem was set up by using correspond relation of the force and the displacement at the interface of lifting and hydraulic system, then the question that the principal diagonal elements of mass matrix were zero is resolved. Meanwhile the effect on the general dynamic characteristic of ellipticity of is considered.

通过卷扬系统与液压系统在界面耦合处的力和位移协调关系，建立诸如M〓+C〓+KX=F形式的机械卷扬-液压均衡系统综合数学模型，模型中考虑了卷筒椭圆度偏差以及直径偏差对整体动态性能的影响，解决了耦合后数学模型质量矩阵主对角线元素奇异的问题。

In 1928 and 1929, the society adopted a bend sinister gules, a type of diagonal red line borrowed from heraldry. The bend was dropped after 1930, following the introduction of a crest bearing the face of a cyclops and the Hebrew inscription , meaning Anak, both affixed to a capital letter T.

至 1929 年间，他们用了一条红色的诡异的曲线，该曲线是源于纹章学中的一种红色对角线。1930 年后，该曲线被弃用，取而代之的是一个独眼巨人面的纹饰，同时还配有希伯来文，以表示阿纳，两个标志都附加着大写字母 T。

From its founding in 1908 to 1927, the society identified itself only by the name "Anak" or "Anak Society". In 1928 and 1929, the society adopted a bend sinister gules, a type of diagonal red line borrowed from heraldry. The bend was dropped after 1930, following the introduction of a crest bearing the face of a cyclops and the Hebrew inscription , meaning Anak, both affixed to a capital letter T.

从1908年建立到1927年，该协会仅用&阿纳&或&阿纳协会&来代表自己。1928至1929年间，他们用了一条红色的诡异的曲线，该曲线是源于纹章学中的一种红色对角线。1930年后，该曲线被弃用，取而代之的是一个独眼巨人面的纹饰，同时还配有希伯来文，以表示阿纳，两个标志都附加着大写字母 T 。

Furthermore, as the information of the point events in a rectangle is not enough, the algorithm can permit us to estimate the K function corresponding to the upper limit of the distance scale i.e.

此外，当矩形研究区域中点事件的信息不足时，这种算法可以允许计算接近到距离尺度的上限（即矩形对角线长度的一半）对应的K函数。

Its weaknesses: repeated sampling of pixels, recursion, and it is designed to leak on the diagonals.

它的缺点：重复取样的像素，递归，它的目的是泄漏的对角线。&/页&

Growth of cultured winged pearl oyster, Pteria penguin was studied in 20 months in Li'an Lagoon, Hainan, south China. The growth parameters of maximum diagonal length, shell length, hinge length and total weight were measured monthly and described using y=y(subscript ∞)/superscript (1+e-k+d sin (2п/365.25).

对海南黎安港的企鹅珍珠贝养殖群体的生长进行了20个月的观察，每月测量其壳高、最大对角线长、绞合线长和总重四个生长指标，并用模型y=y/1+e(上标-k+d sin (2п/365.25)分别拟合这四个指标的生长曲线。
