GCSE自然科学笔试怎样复习?哪能少了背那些单词，GCSE期的自然科学类专精课程主要主要包括GCSE生物、GCSE化学、GCSE力学、GCSE Combined Science等。对于我国学生来说，GCSE自然科学类专精课程症结不只是科学知识的掌控，更是适应自然环境英语教学讲课、掌控自然科学专精词语以及英语教学作答等各方面。能说，我国学生掌控了自然科学专精课程私有英语词语，词汇各方面闯关，GCSE期自然科学类专精课程的自学能少一半苦恼!

GCSE自然科学笔试怎样复习?哪能少了背那些单词，GCSE期的自然科学类专精课程主要主要包括GCSE生物、GCSE化学、GCSE力学、GCSE Combined Science等。对于我国学生来说，GCSE自然科学类专精课程症结不只是科学知识的掌控，更是适应自然环境英语教学讲课、掌控自然科学专精词语以及英语教学作答等各方面。能说，我国学生掌控了自然科学专精课程私有英语词语，词汇各方面闯关，GCSE期自然科学类专精课程的自学能少一半苦恼!

英国*大的笔试局——AQA笔试局综合性其自然科学专精课程的文本，给我们归纳了这份自然科学类专精课程专供词语表，其中汇聚了GCSE自然科学专精课程初学者需要掌控的*基本上的专供英语词语。

Data

Information, either qualitative or quantitative, that has been collected.

搜集到的认定或定量分析重要信息。

Error

See also uncertainty.

同“uncertainty”。

Measurement error

The difference between a measured value and the true value.

量测值与真实*值之间的数值。

Anomalies

These are values in a set of results which are judged not to be part of the variation caused by random uncertainty.

几组结论中的值，那些结论被推论为不属于由不确认定变动引发的部分结论。

Random error

These cause readings to be spread about the true value, due to results varying in an unpredictable way from one measurement to the next. Random errors are present when any measurement is made, and cannot be corrected. The effect of random errors can be reduced by making more measurements and calculating a new mean.

由于结论在相同的量测中以不容预估的形式变动，这将引致高度计紧紧围绕真实*值原产。展开任何人量测时单厢出现瓦卢伊，因此瓦卢伊无法被纠偏。瓦卢伊的影响能透过展开数次量测和排序捷伊平均数来增加。

Systematic error

These cause readings to differ from the true value by a consistent amount each time a measurement is made. Sources of systematic error can include the environment, methods of observation or instruments used. Systematic errors cannot be dealt with by simple repeats. If a systematic error is suspected, the data collection should be repeated using a different technique or a different set of equipment, and the results compared.

每天量测时，高度计与真实*值的比值是完全一致的。库季的作者主要包括自然环境、量测方法或采用的科学仪器。库季无法透过单纯的数次重复试验化解。如果揣测存在整体性数值，则应采用相同技术或相同电子设备数次重复统计数据搜集，并较为结论。

Zero error

Any indication that a measuring system gives a false reading when the true value of a measured quantity is zero, eg the needle on an ammeter failing to return to zero when no current flows. A zero error may result in a systematic uncertainty.

当被量测的真值为零时，量测系统给出了错误高度计的指示，如无电流透过时，安培计上的指针指向不是零。零数值可能引致系统不确认定。

Evidence

Data which has been shown to be valid.

已被*为有效的统计数据。

Fair test

A fair test is one in which only the independent variable has been allowed to affect the dependent variable.

公平测试只允许自变量影响因变量。

Hypothesis

A proposal intended to explain certain facts or observations.

为解释某些事实或观察而提出的提议。

Interval

The quantity between readings, eg a set of 11 readings equally spaced over a distance of 1 metre would give an interval of 10 centimetres.

高度计之间的间隔量(如几组11个高度计，在1米的距离上等距原产，则间距为10厘米)。

Precision

Precise measurements are ones in which there is very little spread about the mean value. Precision depends only on the extent of random errors – it gives no indication of how close results are to the true value.

精确量测是指在平均数上有很小的数值。精度只取决于瓦卢伊的范围，但并没有指出结论与真实*值有多接近。
