查询词典 hadamard criterion

With the implement of urbanization, there're thousands of small towns to construct. However, corresponding criterion still haven't come out ,such as water and drainage quota, which result in no standard to refer to, what's more, absenting systemic researches on variation rules and coefficients of total water and wastewater in towns. Therefore, the construction of many towns takes on luxury evidently.

随着城镇化战略的实施，目前我国有数以万计的小城镇亟待建设，但是，与小城镇建设相匹配的基础设施建设规范尚未出台，致使小城镇给排水工程建设过程中无标准可依，更缺乏小城镇用水量和排水量变化规律以及变化系数的系统研究，贪大求全、不讲科学地追求高标准的现象较为明显。

Only with such characteristics, the movement equations can be expressed as matrices, and the idea of transforming the movement equations to the simplest form through a nonlinear transformation can be realized;(2) The form of Zi =Yi + YTH2i Y + Y7H3i Y(2)+ Y(2)T H4i Y(2)+ YTH5i Y(3) is adhibited in the nonlinear transformation, so that the multivalued problem caused by the nonlinear transformation is avoided, and the higher order transformation can be taken next;(3) The fourth order nonlinear transformation matrices H21,H31,H41 and H51 are derived, by which the original movement equations of electric power system is transformed to Jodan form in Z space;(4) By use of the fourth order nonlinear transformation, the approximate expression of the stability boundary is obtained, in Z space it is Z1= 0,in Y space it is Y1 + YTH21 Y + YTH31 Y(2)-i- Y(2) TH41 Y(2)+YTH51 Y(3)= 0;(5) The criterion used in this paper to judge whether the system critical unstable is simple and quick;(6) The method used in this paper is a direct method, and no need to construct an energy function.

正是由 于电力系统的运动方程具有这样的特性，才能写成矩阵的形式，通过非线性变换将电力系统的运动方程变换为最简单的线性形式的思想才能得以实现；（2）将通常运用于电力系统暂态稳定性分析的Normal Form变换的形式由 Yi＝ Zi＋ ZTh2riZ变形为 Zi＝ Yi＋YTH2iY＋YTH3iY（2）＋Y（2）TH4iY（2）＋YTH5iY（3），从而使得在对持续故障轨线实施同样的非线性变换以确定临界切除时间时，避免了非线性变换带来的多值性的问题，而只有在没有多值性问题的困扰下，才能采用较高阶的变换：（3）推导出了将原始电力系统系统的运动方程变换到Z空间的约当形式的非线性变换矩阵H21、H31、H41、HS1：（4）在运用四阶了「线性变换的情况下，给出了受扰动后系统的稳定边界的近似的解析表达，在Z空间为Z1=0，在y空间为： Y1+YTH21Y+YTH31Y(2)+Y(2)TH41Y(2)+YTH51Y(3)=0 （5）确定临界失稳的判据简单、快捷：对于一个复杂的电力系统，其稳定边界是相当复杂的一个高维曲面，即便是已知系统稳定边界的解析表达，要求出系统持续故障轨线何时与这一高维曲面相交，在数学上几乎是不可能实现的。

The scaling-up rules for four types of agitators are different taken mixing efficiency number as criterion.

Result 3.1 Ultrasound result We amended the criterrion little which Hitachicommpany offered. According as the criterion, it is 1 score if liver tissues have notdifference of elasticity and there are green in the region of interest. It is 2 score ifliver tissues have not significance difference of elasticity and there are blue in greenin the region of interest. It is 3 score if liver tissues have difference of elasticity andthere are green in the region of interest of normal liver tissues and blue in the region of interest of abnormal liver tissues. After examination, we anatomised rats and gotliver tissues for pathologic checkout.

结果 3.1超声检查情况根据日立公司提供的评分标准，稍做修改，将肝组织弹性无差异，取样框内颜色均为绿色，评为1分；肝组织弹性无明显差异，取样框中颜色为绿色中微微带点蓝色，评为2分；肝组织弹性有差异，取样框内正常肝组织弹性变化为绿色，病变肝组织弹性变化为蓝色，评为3分。

But at the same time, it can not be just localized at class, not be astricted into the criterion of the teaching material, not be confined in the teachers' guidance and the disposed circle.

但同时不应当局限于课堂上，不应当束缚在教材的规范中，不应当限制于教师的指导与布置的圈子内。

After the result of cohesion-friction model is compared with Coulomb Criterion, it is found that when the results of shearing strength are many and adjacent the strength parameters can not be regressed by least square method, instead the results should be divided into some beelines at that time according to the cohesion-friction model.(4) Discuss the characters of hard structural plane and weak structural plane: The adhesive friction theory is applied to research the changing course of shear area of hard structural plane and its influence on shear stress.

3介绍了岩石强度理论中的粘接摩擦模型，运用此模型分析依附型滑动面的演化过程，并将其推广到边坡岩土体抗剪强度的选取，讨论了不同法向应力下峰值强度和残余强度随法向应力的变化规律，在此基础上给出抗剪强度的选取模式，讨论了对实际取值结果的影响，并与传统的Coulomb准则进行了比较分析，指出直剪试验的法向应力在小应力区的点较多且抗剪强度结果差异不大时，不宜直接运用最小二乘法回归抗剪强度参数，此时应结合粘接摩擦模型对结果进行线性分段。

Introduce the cohesion-friction model of rock strength theory, and extend the model to select the strength of sliding plane, discuss the variation rules of peak strength and residual strength under different normal stress, and then present the selection model of shearing strength. After the result of cohesion-friction model is compared with Coulomb Criterion, it is found that when the results of shearing strength are many and adjacent the strength parameters can not be regressed by least square method, instead the results should be divided into some beelines at that time according to the cohesion-friction model.(4) Discuss the characters of hard structural plane and weak structural plane: The adhesive friction theory is applied to research the changing course of shear area of hard structural plane and its influence on shear stress.
