In the Mu Us desert, either vertical distributions of soil moisture isogram before irrigation or vertical distributions of soil moisture isogram after irrigation shows obviously vertical-layered character. When the irrigation is finished 24 hours later, there is little correlation between vertical distributions of soil moisture isogram before irrigation and vertical distributions of soil moisture isogram after irrigation. All of probability distribution of soil water content before irrigation are left-skewed distribution, but some of probability distribution of soil water content after irrigation is left-skewed distribution, some is right-skewed distribution or normal distribution. The distributed pattern shows different between the probability distribution of water depth of rain gauge and that of soil moisture in horizontal section of different depth. There is close correlation between the distribution of water depth of rain gauge and that of soil moisture in horizontal section, but the correlation debases as the horizontal section turns deeper. Also after irrigation close correlation occurs between the distribution of soil moisture of layers bordering upon each other, but which reduces with space of different layers being larger.
在毛乌素沙地,喷灌前后土壤含水率等值线垂直分布均具有显著的垂直分层特征;在喷灌结束24h后,喷灌前土壤含水率的垂直分布与喷灌后土壤含水率的垂直分布间地相关性较弱;灌水前土壤初始含水率的概率分布形态均表现为较典型的左偏态分布,灌后土壤含水率分布形态表现为左偏态、右偏形态或正态分布;雨量筒水深概率分布与土壤不同深度剖面层水平方向的含水率概率分布在形态特征上表现出一定程度的差异,雨量筒水深分布与水平层土壤含水率分布、灌后相邻深度层土壤含水率分布、之间的相关程度较高,其相关性随着剖面深度和层间距的增加而降低。

If the output image is in CMYK images for printing we recommend a Gamma value of 1.8; if the image is in RGB color mode of the device output, such as other displays and film recorder or an RGB printer, the gamma value is generally set to 2.2; If the image is used to a different application or platform for output, the Gamma value of 1.8 has a much wider applicability.
如果负入图像是用于印刷的CMYK图像倡导拔取Gamma值为1.8;如果图像不兵在RGB色彩模式的撤备上负不入(如其他的表现器,胶片记录仪或RGB打印机),Gamma值凡是撤定为2.2 ;如果图像用到其他的答用步调或平台举行负入,1.8的Gamma值则具有更普及的适用性。

The gray balance curves were obtained by the gray balance function and regression analysis. The main works: The parameters in the mathematic models were ascertained, as well as all the regression functions. The models included the relation between the ink quantity and the solid density, the relation between the gamma and printing contrast, the printing reproduction curves, the dot-gain curves and the dot-gain compensation curves. The fitting accuracies of the regression models were checked out by the correlation coefficient or multiple correlation coefficients. The effect that the ink had on the solid density and the gamma on the printing contrast were analyzed. And the methods of choosing the ink and gamma were gained.

Effects of gamma irradiation on shoot regeneration from leaf and bud growth in vitro of strawberry 1 The leaf was very sensitive to the gamma irradiation, and 'Toyonoka' was more sensitive than 'Akihime'. The LD50 (50% decrease of generation) of strawberry leaf was between 10 and 20 Gy. 2 Strawberry leaves were inoculated in vitro at 8 d-15 d after gamma rays irradiation, and the shoot regeneration rate from of 'Toyonoka' increased at 10 Gy and almost no difference from 20 Gy to 40 Gy. The positive effect dose for 'Akihime'.was from 10 Gy to 30 Gy, however, 40 Gy decreased shoot regeneration rate.
