equation: condition | 条件方程式
| An equation which expresses exactly certain relationships that must exist among related quantities, which are not independent of one another... more | 表示相关量存在的某种关系的等式，这些量不是彼此独立的，先验存在，与观测值所要求的关系不同。 |
|
|
equation: correlate | 联系数方程 | An equation derived from an OBSERVATION or CONDITION EQUATION, using undetermined multipliers, and expressing the condition that the sum of ... more | 由观测方程或条件方程导出的一种方程。其导出方法是：使用不定因子，将不定因子引入观测方程或条件方程中，然后求出由这些方程所得剩余误差的平方和为最小时的条件表达式。 |
|
|
equation: error | 误差方程
| The probability equation which expresses the laws of the occurrence of ACCIDENTAL ERRORS. The error equation is the basis of the method of L... more | 表示偶然误差事件规律的概率方程。误差方程是最小二乘法的基础。最小二乘法在测量平差中使用，用来确定观测结果的最或然值。 |
|
|
equation: Laplace | 拉普拉斯方程
| An equation which expresses the relationships between ASTRONOMIC AZIMUTH, GEODETIC AZIMUTH, and the ASTRONOMIC LONGITUDE and GEODETIC LONGIT... more | 表示天文方位角，大地方位角和天文经度、大地经度之间关系的等式。 |
|
|
equation: normal | 法方程
| One of a set of simultaneous equations derived from OBSERVATION, CONDITION or CORRELATE EQUATIONS. In a least-squares adjustment, values ob... more | 由观测方程、条件方程或相关方程导出的一组联立方程中的某一方程。在最小二乘法平差中，用法方程解得的值（直接求解或通过相关方程求解）代入观测方程或条件方程中以求得所需的改正值。 |
|
|
equation: observation | 观测方程
| A CONDITION EQUATION which connects interrelated unknowns by means of an observed function. | 通过观测函数把相关未知数连接起来的一种条件方程。 |
|
|
equation: personal | 个人观测误差
| See PERSONAL EQUATION. | 感知某一现象与对其作出反应之间的时间间隔。个人观测误差有正有负，因为观测者既可能预知事件的发生，又可能在实际看到事件发生后做记录。此误差被视为恒定系统误差。此术语因其为一种人为误差而被保留。它对时间观测格外重要，用于确定精确时计改正。 |
|
|
equation method | 方程法
| In tidal terminology, an elaborate non-harmonic method for the prediction of TIDES. | 在潮汐领域指预报潮汐的一种非调和方法。 |
|
|
equation of time | 时差
| The CORRECTION to be applied to 12 hours plus UNIVERSAL TIME to obtain the Greenwich HOUR ANGLE of the SUN, or more generally the CORRECTION... more | 格林尼治太阳时与世界时加12小时所得时间之差，或者更普遍的本地的平均时与本地的太阳时角加12小时所得时间之差。 |
