At first, this dissertation takes the natural gamma log as an example to put forward the regularized least-squared deconvolution theory, with which not only the effect of the surrounding formation is removed, but al so the effects of the well logging velocity, sampling interval, the ratemeter time constant, the detectorlength and the formation dip-angle are re moved.

首先，本文以自然伽马测井曲线为例，研究了正则化最小乘方反褶积方法。应用该方法，不仅消除围岩对自然伽马曲线读数的影响，而且消除测井速度、测井采样间隔和率表电路时间常数的影响。

Usually they are designed in a gamma configuration, for simplicity, and without a regenerator.

通常，他们的设计伽玛配置，为简单，并没有再生。

The log data of Samandepe gas field in the Amu Darya Right Bank of Turkmenistan are old in logging suites, limited and inconsistent in logging items between early exploratory wells and later development wells. Based on the correlation of different log data, the suitable log data are selected from the available logging suites to build up a mathematical statistical model of artificial fitting acoustic curve. The non-linear correction of neutron and gamma ray data was performed to ensure the relative rationality and uniformity of log interpretation.

针对土库曼斯坦阿姆河右岸萨曼杰佩气田测井资料存在系列老、项目少、早期探井和后期开发井测井项目不统一的现状，通过不同测井资料问的相关分析，合理选用已有测井系列的测井资料，建立人工拟合声波曲线的统计数学模型；通过对中子伽马资料进行非线性校正，保证了测井解释评价资料的相对合理和统一。

We show that the expression of BCL11A, a repressor of human gamma-globin expression identified by genome-wide association studies, differs between mouse and human.

作为已被大量的基因组相关研究证实的一种人γ-球蛋白表达抑制剂，BCL11A的表达在鼠和人是不同的。

The paper studies the auto-covariance estimation of Gamma distribution by using the asymptotic behavior of student U -statistic,gives the large sample interval estimation for the scale parameter,and carries out the computing simulation according to the method of random simulation.

利用学生氏U－统计量的渐近性质，研究伽玛分布的自协方差估计，同时给出了尺度参数的大样本区间估计，并采用随机模拟的方法进行计算模拟

Looking at any of the saros catalogs ( e.g., Saros 145) one can see how the value of gamma changes with each eclipse in a series.

其实在掌握沙罗序列的编号原理后，可以用程序先把各个序列号计算出来。

All eclipses in an even numbered Saros series occur at the Moon's descending node and the Moon moves northward with each succeeding member in the family (i.e., gamma increases).

所有的日食在沙罗周期里排序发生在月球下落点和月球向北移动。
