The first rank derivative is a reflection of curve change and its rate, at certain range, if the sign of the first rank derivative has changed, the logging value of the correspondence depth point means maximum in this range; the second rank derivative is the knaggy property reflection of curve, at certain range, if the sign of the second rank derivative has changed, the correspondence depth point represent the inflexion of geophysical logging curve, it＇s also a turning point of the reflection of knaggy change property of the curve, it is the interface of stratum.

测井曲线的值是深度的函数，测井曲线的一阶导数表示了曲线变化的趋势和变化的快慢，在某一范围内，当一阶导数呈现符号转换时，相对应的深度点的测井值即为该范围内极大值；测井曲线的二阶导数则表示曲线的凹凸性，在某一范围内，当二阶导数呈现符号转换时，相对应的深度点代表了测井曲线的拐点，即反映曲线凹凸性变化的转折点，亦即地层的分界面。

The paper studies the distribution characteristics and determinants of job vacancies. The parameter estimation is based on the two-stage Tobit procedure. The main statistical results are as follows: There is a positive correlation between the hiring scale and job vacancy incidence, while there is a negative correlation between the qualification vacancy rate and the hiring scale. The higher the labor turnover rate in units, the higher the job vacancy incidences and the vacancy rates are. The 98.39% of institutions with prospects have labor needs, and 39.53% of units declining say they will hire new staff. After decomposing the Theil Index which reflects the gaps among vacancy rates, the differences among vacancy rates of different units are mainly from the inner causes of various groups, and the intergroup reasons are not main ones.

本文利用两阶段Tobit模型对国内的职位空缺统计数据进行了估计，发现：用人机构的雇佣规模与职位空缺发生率正相关，而职位空缺率则与机构的雇佣规模呈现负相关的关系；机构员工流动率越高，职位空缺发生率以及职位空缺率越高；在景气指数为"看涨"的机构中98.39%表示存在用人需求，而景气指数为"看跌"的机构里只有39.53%的机构表示会招募新员工；在对反映职位空缺率差距水平的泰尔指数分解后发现机构职位空缺率之间的不同主要是由于各类分组的组内原因导致的，而组间的原因并不是主要的。

Mr Lacker who was sceptical that inflation would fall much from current levels in spite of high unemployment and spare capacity in the economy said at some stage the Fed would reach a tipping point at which these purchases would provide a much stronger boost to spending than at present.

莱克尔表示，在某一阶段，美联储将达到一个临界点：购买证券对支出的推动将远大于当前。尽管失业率高企及经济中存在空闲产能，莱克尔对于通胀将从当前水平大幅回落表示怀疑。

Maximum likelihood estimation of spatial lag and spatial error regression modes, some specification tests for spatial autocorrelation and optimization methods for ML are also set forth in this section.

在标准回归模型中可以以两种截然不同的方式来合并空间相关：一是将空间相关表示为因变量的一个空间滞后，二是将空间相关表示为一个误差项的空间自回归结构。
