根据基本假设，借鉴前人研究成果，引入有效面积系数，推导出简式活性炭二维深层过滤理论公式。

The result shows that the relationship between suction and suctional strength is unlinear, the difference of suctional strength in the two paths that desorption and absorption of moisture is not obvious under a certain cell pressure. According to the result of triaxial test, a shear strength formula of ningming unsaturated expansive soils is put forward.

结果表明宁明膨胀土的吸力与吸附强度之间的关系是非线性的，一定的围压作用，吸湿和脱湿路径下的强度有差异但不明显，由此提出宁明非饱和膨胀土有效应力强度理论公式。

Practical microstrip antenna problems, such as the effect of superstrate on input impedance and radiation pattern are studied.

根据所得的新公式建立了多层介质覆盖矩形贴片微带天线的积分方程，并利用有效的数值技术求解出上述方程，得到了贴片上的电流分布，进而求出天线输入阻抗和辐射方向图。

The argument in such syllogisms is valid by virtue of the fact that it would not be possible to assert the premises and to deny the conclusion without contradicting oneself.

在这样一个三段论中，推理是有效的，结论成立。因此，考生应非产清楚，一个三段论中有两个前提，一个结论，用公式表示为

During the debates in Parliament it was observed that the proposed formula effectively debarred Catholics from the throne, whilst it committed the king to no particular creed, as no man knows what the creed of a faithful Protestant is or should be.

在议会辩论中有人认为，拟议的公式有效地禁止天主教徒的宝座，而它承诺的国王没有特别的信仰，因为没有人知道什麼是对的信仰新教的忠实或应。

A novel correlation measurement of color image has been proposed. An adaptive weight, which is relative to the color histogram correlation of stereo image pair, bas been used to find the disparity, and the relationship between the weight and the color histogram correlation has also been worked out and formularized. So the appropriate weight can be determined by the formula for various stereo image pairs.

提出了一种自适应权值的色彩相似性度量方法，有效地抑制了噪声对立体匹配的影响，提出以立体像对左、右图像间的颜色直方图相关系数为标准来调整权值的方法，并通过实验推导出具体的计算公式。

Basic quantities in stellar photographic photometry (in particular, colour index and "effective wavelength") are formulated according to the assumptions that: 1 stellar radiation may be represented by some black body equivalent and 2 within the limits of a single photometric "receiver", intensity-wavelength relationship of the radiation may be taken as linear.

本文对着当前的发展，综述了照相方法在恒星光度学中的地位。接着用两个简单的假设，即星体幅射的黑体近似和累积亮度范围中的直线近似，把恒星光度学中的基本定义(如有效波长、等光波长和色指数等)和主要问题(如空间红化，亮度效应等)表以公式。
