5)evenness index均匀度 1.Adopt diversity index,evenness indexand common index to analyze.对凉水国家自然保护区土壤虫的生态分布进行了研究,采用多样性指数、均匀度指数、共同性指数进行了分析。 6)UNIF (uniformity)均匀度,均匀性
the evaluating results by the correlation were worse than that by the formula when velocity distribution uniformity was less than 60%.However,the flow that uniformity is worse always need to further improve its structure,the uniformity was just providing a basis for improvement.Therefore,the results...
1.The uniformity coefficient of chemical applied can be calculated using the modified formula of Heermann and Hein.圆形喷灌机采用比例法喷洒化学液,引用赫尔曼—海恩(Heermann-Hein)公式计算喷洒化学液均匀系数。 2.Christiansen uniformity coefficient (CU) was used in this article.喷灌均匀系数是喷灌系统设...
By Bayes’ formula we have \begin{aligned} {{\mathbb {P}}}_{a}\left( \tau _x \wedge \tau _y < \tau _R\;\vert \;X(\tau _R) = b\right)= & {} \frac{{{\mathbb {P}}}_{a}\left( X_{\tau _R}=b\;\vert \;\tau _x\wedge \tau _y<\tau _R\right) }{{{\...
Process for producing scintillation materials of low strain birefringence and high refractive index uniformityThe process produces a scintillation material of formula LnXor LnX:D, wherein Ln is at least one rare earth element, X is F, Cl, Br, or I; and D is at least one cationic dopant ...
According to the method proposed in this paper, the magnetic field uniformity coefficient of the central region of the air gap where the TMR element is located is calculated as an optimisation index. First, fix other parameters to analyse the inner radius r. Magnetic field analyses are ...
The heating uniformity index was used to calculate the uniformity of RF heating. It is the proportion of the change in standard temperature deviations to the difference between the average temperatures of the samples during treatment. The uniformity index (λ) is a parameter that is unique to a...
The online calibration system and the online calibration method mainly solve problems that an existing test method is only used for testing brightness uniformity, tested brightness uniformity index cannot reflect an overall performance of an LED display screen, and ununiformity calibration cannot be ...
In this paper, the functions of the uniformity index of velocity distribution are shown in the following formula: (7) vfn=∣vf∣⋅cosθvfn=vf⋅cosθ (8) ϕ=1−∑f∣vfn−¯¯¯¯vfn∣Af2∣¯¯¯¯vfn∣∑fAfϕ=1−∑fvfn−vfn¯Af2vfn¯∑fAf where vfnv...
