1.The primary purpose of this paper was to study whether or not the different corn testersused to determine the combining ability of a series of inbred lines produce the same effect.Materials adopted in the studies consisted of fifteen inbred lines and six testers.Splitplot design with four replications was used for this study with inbred lines as main plotand testers as subplot.2.Data obtained showed that the above six testers were not equal in reliability as used indetermining the combining ability of the fifteen inbred lines.38—11 and Chun Tsa No.1were most reliable;C.I.7 and Hwa Nung No.1 were least reliable;38—11×C.I.7 andGolden Queen were intermediate in reliability.One tester was enough to determine thecombining ability of a series of inbred lines if it was adequately chosen.3.In analyzing the reliability of the different testers,the results obtained were as follows.If the tester and inbred line determined belonged to the same type (such as flint ordent),usually relative little hybrid vigor could be observed,but if they belonged tothe different type,relative greater hybrid vigor was shown.However,when the testerbehaved as an intermediate type,the resulted hybrid would show neither too high nor toolow in yield.In other words,the intermediate type tester was more reliable in determiningthe combining ability of inbred,lines.4.Experimental results of investigations showed that the reliability of testers was notassociated with the complexity of genetic constitution.38—11 and C.L.7 are inbredsand rather simple in gentical background,but the former was more reliable in determin-ing the combining ability of inbred lines.Chun Tsa No.1 and Hwa Nung No.1 arevarietal hybrid and local variety respectively,and relatively complex in genetic basis hutthey were quite different in reliability for determining the combining ability of inbredlines.5.Besides combining ability,so far as the inheritance of other single character of inbred lineswas tested,equal accuracy was obtained for all testers,no matter how widely differentthey were in types or in genetic complex.6.The results of correlation studies obtained showed that the several chief economic char-acters of inbred lines were not associated with the yield of the top crosses.It might thenbe concluded that any single character of the inbred line could not be used for evaluatingits combining ability.

本文主要研究38—11等6个玉米测验种对测定15个自交系配合力的影响。试验结果证明,以不同测验种测定时其作用是不同的,其中以自交系38—11和品种间杂交种春杂一号测得的效果较好。试验进一步指出,测验种和自交系的籽粒类型相同时,表现杂种优势较小;两者属于异类型时,表现杂种优势较大;中间类型的测验种由于兼具马齿和硬粒的遗传基础,所测得自交系配合力的结果较为可靠。6个测验种在测定除产量以外的其他几个经济性状时,差异并不显著。自交系的产量等13个性状和测交种的产量都没有显著的相关。

In 1975, 1976, Green and Stanley published a method to determine parameters of two-dimensional magnetic and gravity contact surface. In this paper, instead of using difference division to obtain horizontal derivative and Hilbert transformation to obtain vertical derivative, which were used in Green and Stanley's paper, we apply space domain filter. It is explained in theory that satisfactory result may be obtained. Model computation supports the theoretical derivation. In comparison with Green and Stanley's...

In 1975, 1976, Green and Stanley published a method to determine parameters of two-dimensional magnetic and gravity contact surface.

It is explained in theory that satisfactory result may be obtained. Model computation supports the theoretical derivation. In comparison with Green and Stanley's method. The present method can filter out high frequency noise in the data and get equal accuracy in horizontal and vertical derivatives so as to obtain better results in the inverse problem.

1975年、1976年格林和斯坦利发表了求二维接触面参数的一个方法。本文试图在他们工作的基础上,用空间域滤波来代替格林和斯特利用差商求水平导数和用希尔伯特变换求垂直导数的方法。文中给出了应用空间域滤波计算重、磁异常水平和垂直导数的方法。模型试验证实了理论上的推断。与差商和希尔伯特变换方法相比,优点在于它既能同时滤掉高频干扰,又能使求得的垂直导数和水平导数具有相同的精度,进而提高反演结果的精确度。

For a set of correlated observations with equal accuracy,[uu]/(n-1) is a biased estimation standard error,E([uu]/(n-1)) = (1 -ρ)σ2. And for the average of n observations, its standard

一组不独立的等精度观测值用[vv]/(n-1)估求中误差,将平均使估值缩小到1-ρ倍,而n次观测值的平均值中误差不是单次观测中误差的1/n,而是1/(n/(1+(n-1))·ρ];这里ρ是各观测值间的平均相关系数。在观测值相关的条件下,limn→∞vx=ρ·σ、≠0,即大数定律不成立。所谓内部符合误差,就是由一组相关的观测资料,用独立前题下导出的公式所求出的偏小的平均值中误差估值。
