Based on the experimental results and dimensional analysis ,the empirical equations for horizontal and vertical Penetration depths are obtained respectively .

在实验基础上，通过量纲分析，分别得出了气体无量纲水平和垂直穿透深度的经验表达式。

For radians, these functions are found in boost/units/cmath.hpp These behave as one expects, with trigonometric functions taking an angular quantity and returning a dimensionless quantity, while the inverse trigonometric functions take a dimensionless quantity and return an angular quantity

对于弧度，这些函数定义在 boost/units/cmath.hpp 。这些函数就像你想的那样，三角函数以弧度数量为参数返回一个无量纲数量，反三角函数以无量纲数量为参数返回一个弧度数量

What good are dimensions then, if we really measure dimensionless numbers?

既然我们测量的是无量纲的数字，那量纲有什么用呢？

It is not satisfactory from a dimensional standpoint, since the power to which we raise e must be dimensionless.

从量纲的观点来看，它是不能令人满意的，因为e的幂必须是无量纲的。

Its benefit is that different structural sizes can be controlled by single design variable, such as the thickness of plate element and the area of bar element can be controlled by single dimensionless design variable.

采用无量纲设计变量为了适合工程实际的设计变量连接，利用无量纲设计变量，其好处是可以跨单元、跨截面的用同一个设计变量控制不同类型的结构尺寸(如板单元的厚度、杆单元的截面面积等)。

In addition to the role of Taigang, there are a Department of Chuan Ling, Yang horsewhip in hand, dressed in opera costumes Yousi seven Zhi Maguan goods, referred to as "charge-gang officer", responsible for the inspection tribute, and four government offices as if the ban stands " Yayi care network."

角色除抬杠者外，尚有一名身系串铃，手扬马鞭，装扮犹似古装戏中的七品芝麻官者，谓之"押纲官"，负责查验贡品，及四名犹如衙门站班的"护纲衙役"。

Dimensional analysis was constructed to derive the dimensionless functions of a spherical indenter with 1 mm in diameter.

采用量纲分析法，建立了直径1 mm球形压头的无量纲函数。

The formation in the world of professional maintop pattern design software, well known for not more than five, where the corporations'entering there are three products, that is,巴可 the company's Fortune; Hungarian Jura company Geoli Jspre software and now has more than 10 introduces a set of security design software, distribution in the Ministry of public security and the plant and design centre.

纲前寰宇上变成商品化的副业版纹安排软件好众，闻名的不不及五家，其洋出去洋国阛阓的有不一财产物，即巴可公司的Fortune；匈牙利Jura公司的Jspre软件和Geoli，纲前不国外共引进了10缺套不攻伪安排软件，漫衍在公安部和各印钞厂及安排洋心。

To the problem that the isotropy and the technological efficiency of the parallel kinematic machine based on Stewart platform are not satisfactory, a novel architecture of 6-DOF 3-dimensional platform parallel kinematic machine (6-DOF 3-D PPKM) based on the 2-2-2-SPS 3-D PPR is presented. The technological efficiency of design of the parallel kinematic machine is analyzed. Its workspace and the effect of design parameters to the workspace volume are studied. By using the submatrices of Jacobian matrix and force Jacobian matrix, the kinematics/mechanics transmission isotropic indices, kinematics transmission indices, load-bearing capacity indices at any configuration of the parallel kinematic machine are proposed, respectively.
