| 摘要: |
| 文中提出了要使～14C年龄测量误差为极小的数据处理方法。它以测年误差公式根号内的表达式为口标函数,从仪器同定了的甄别阈窗口开始搜索,寻找最佳窗口,求得最小误差下的优化计数。这种方法对扩大年代测定范围是有好处的。需要指出的是它采用直接法优化,数值计算必须由计算机来完成。 |

| ON OPTIMIZATION OF MEASURING DATA OF 14C AGE |
|
|
| Abstract: |
| This paper presents an optimum processing method for the measuring data of 14C age. A whole expression in square root of age-error formula has come into use as a destination function. The computer program automatically searchs the upper-down thresholds called window, fixed by the instrument, then looks for an optimun window defined as a minimum error, and finally calculates the values of results. Extending the range of 14C age measurement, the method is useful for some older samples. It’s necessary to point out that the method is a direct opitimization and must be executed by a computer. |
