查询词典 approximate differentiability

Although factors that affect the quality of an image captured at high speed include scene luminance, aperture size (f-number, f/#), shutter speed, and field of view, a simple calculation can determine the approximate shutter speed needed for such an application.

尽管影响高速捕捉图像质量的因素包括场景的亮度、镜头大小、快门速度和视野，不过对于这样的应用场合可以很简单就计算出大致所需的快门速度。

As for the factitiously specified allowable values,such as allowable deflection,allowable amount of wear,and so on,their magnitudes,which are confirmed on the basis of empirical formula,often have an interval value or a limit value,therefore they can be described suitably by minor type membership function, As for various strength values of parts,such as tensile strength,compression strength,contact strength and so on,their magnitudes,which are often confirmed only by approximate mean,can be described suitably with middle type membership function.

对于人为规定的各种许用值，如许用挠度值、许用磨损量等，根据经验公式确定它们的大小时往往有一个区间或一个极限值，宜用偏小型隶属函数描述，对于零件的各种强度值，如抗拉强度、抗压强度、接触强度等，实际中往往只能确定其近似的均值，宜用中间型隶属函数描述。

The method is finding an interior point in the feasible region, followed by the central path, we can find a approximate optimal solution.

Firstly an approximate linear model was obtained by confining the regression function in a functional space with finite dimension. Then the interval estimator was proposed by Fiducial inference.

首先将回归函数限制在一个有限维函数空间中，得到一个近似的线性模型，在此基础上，由Fiducial推断给出了误差方差的区间估计。

Now the controllability theory in linear systems over the field R of real numbers has been heavily studied. This theory is efficacious for analyzing the characters which are determined by the value of physical parameters and system structure, nevertheless a practical system has a definite structure and has approximate, even unknown parameter sometimes because of a limit to experiment conditions, or a limit to making technology, the errors of observation. It is inconvenience for a linear system over the field R of real numbers to analyze the structure characters of a physical system, such as structural controllability.

目前，实数域上的系统的完全能控性理论研究已经很成熟了，它用于分析系统结构和物理参量的值共同决定的那些性能是有效的，然而，在工程中，由于实验条件或者制造工艺上的限制和观测上的误差，以及人为地对数据的近似处理，一个实际系统往往其结构是确定的，而参数只是近似的甚至未知的，实数域上的系统不便于分析物理系统的结构性质，如结构能控性。
