 express equation
 Now let us re-express Equation A2 into the desired result using the fact that we are only interested in Gaussian processes.
 Stress susceptibility index (1-Yd/Yp) / (1-∑Yd/∑Yp) used to determine drought resistance on the field is the alter form of drought resistance coefficient (Yd/Yp) . The correlative coefficient above both is r= -1. Therefore, the former doesn't improve the defect of the latter. Using thirty winter wheat varieties as trial materials, after two years experiments, the concept of drought resistance index in crops was put forward, its expressing equation is. the yield in dryland × drought resistance coefficient... Stress susceptibility index (1-Yd/Yp) / (1-∑Yd/∑Yp) used to determine drought resistance on the field is the alter form of drought resistance coefficient (Yd/Yp) . The correlative coefficient above both is r= -1. Therefore, the former doesn't improve the defect of the latter. Using thirty winter wheat varieties as trial materials, after two years experiments, the concept of drought resistance index in crops was put forward, its expressing equation is. the yield in dryland × drought resistance coefficient / average yield in dryland, it makes the drought resistance coefficient (physical index) correlate well with the yield in dryland (agronomy index) and is suited for breeder. 田间测定农作物抗旱性所使用的胁迫敏感指数(1-Yd/Yp)/(1-∑Yd/∑Yp)是所谓抗旱系数Yd/Yp的变型,二者相关系数r=-1.因此,前者并没有改进后者的缺陷.作者以30个冬小麦为材料,经过两年试验,提出了作物抗旱指数的概念,其表达式:品种旱地产量×抗旱系数/供试品种旱地平均产量,使抗旱生理指标的抗旱系数与农艺指标品种旱地产量得到较好的结合,更适合育种工作者应用. A mechanical analysis on liquid medium filled in double-layer combined casing was conducted. An expressing equation of pressure transfer coefficient of the medium was deduced. The alteratlon law of the equivalent stresses on the inside wall of the combined casing with the elastic module of the volume of the liquid K and with the external pressure Pw when K = 7. 7 × 10-3 MPa were also analyzed. Therefore a theoretical basis was created for study on annular medium of the combined casing and the damage prevention...

The values a and b are determined by an established calibration curve of measured phase. The direct contract method of quantitative phase analysis for trace mass samples... The liner expressing equation correlating sample mass and the diffraction intensity, y=a+b I n, was deduced mathematically from exponent equation of the X ray diffraction intensity, with correlation coefficient r =0.995 and with one hundredth allowable error of quantitative phase analysis being taken into account. The values a and b are determined by an established calibration curve of measured phase. The direct contract method of quantitative phase analysis for trace mass samples was established. The test method determining the critical values between the trace mass samples and limited thickness samples and the absorption revision method of limited thickness samples were established. These methods have been used in determining the content of free silica of respirable dust and the evaluated limit can be downed to 0.01 mg. 从Ｘ射线衍射强度的指数方程出发，考虑到１％的允许误差，经数学处理建立了微量薄膜样品的质量与衍射强度间的线性方程ｙ＝ａ＋ｂＩｎ；ａ，ｂ值用被测物相纯样的外标曲线确定，线性方程的相关系数ｒ＝０．９９５，从而建立了微量薄膜样品的物相定量分析直接对比法。同时，建立了微量样品和有限厚样品间临界值的实验方法及有限厚样品衍射强度的吸收校正方法。所建立的方法用于矿山呼吸性粉尘中αＳｉＯ２的定量测定，检出下限达０．０１ｍｇ。 << 更多相关文摘
