原标题：掌控这些GCSE科学专用英语词汇，GCSE科学成果拿9不难
GCSE期间的科学类课程首要包括GCSE生物、GCSE化学、GCSE物理、GCSE Combined Science等。关于我国学生而言，GCSE科学类课程难点不只在于常识的掌控，更在于 习气全英文授课、掌控科学专业词汇以及全英文答题等方面。可以说，我国学生掌控了科学课程专有英文词汇，言语方面过关，GCSE期间科学类课程的学习可以少一半烦恼！
英国最大的考试局——AQA考试局归纳其科学课程的内容，给我们总结了一份科学类课程专用词汇表，其间集合了GCSE科学课程学习者需要掌控的最根柢的专用英语词汇。
正在温习GCSE的小火伴们可以拿来运用，预备学习GCSE科学课程的小火伴们也可以提前晓得哦~
AQA Subject specific vocabulary (Science)
Accuracy
A measurement result is considered accurate if it is judged to be close to the true value.
假定测量成果被判别为接近真实值，则被认为精确性高。
Calibration
Marking a scale on a measuring instrument. This involves establishing the relationship between indications of a measuring instrument and standard or reference quantity values,which must be applied. For example, placing a thermometer in melting ice to see whether it reads zero, in order to check if it has been calibrated correctly.
在测量仪器上标刻度。这触及符号测量仪器指示与有必要使用的标准或参阅量值之间的联络。例如，在融化的冰中放置一个温度计，看看它的读数是不是为零，以查看其是不是被正确校准。
Data
Information, either qualitative or quantitative, that has been collected.
搜集到的定性或定量信息。
Error
See also uncertainty.
同“uncertainty”。
Measurement error
The difference between a measured value and the true value.
测量值与真实值之间的
过失。
Anomalies
These are values in a set of results which are judged not to be part of the variation caused by random uncertainty.
一组成果中的值，这些成果被判别为不归于由不断定性改变致使的有些成果。
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.
因为成果在不一样的测量中以不可以猜测的方法改变，这将致使读数环绕真实值分布。进行任何测量时都会呈现随机过失，而且随机过失不能被纠正。随机过失的影响可以经过进行多次测量和核算新的均匀值来削减。
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.
每次测量时，读数与真实值的差值是共同的。体系过失的来历包括环境、测量办法或运用的仪器。体系过失不能经过简略的重复实验处置。假定置疑存在体系性过失，则应运用不一样技能或不一样设备重复数据搜集，并比照成果。
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.
当被测量的真值为零时，测量体系给出了差错读数的指示，如无电流转过期，安培计上的指针指向不是零。零过失可致使使体系不断定性。
Evidence
Data which has been shown to be valid.
已被证明为有用的数据。
Fair test
A fair test is one in which only the independent variable has been allowed to affect the dependent variable.
公正查验只答应自变量影响因变量。
Hypothesis
A proposal intended to explain certain facts or observations.
为说明某些实际或调查而提出的提议。
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.
读数之间的间隔量(如一组11个读数，在1米的间隔上等距分布，则间隔为10公分)。
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.
精确测量是指在均匀值上有很小的过失。精度只取决于随机过失的规模，但并没有指出成果与真实值有多接近。
Prediction
A prediction is a statement suggesting what will happen in the future, based on observation, experience or a hypothesis.
猜测是一种根据调查、经历或假定对将来将会发生作业的陈述。
Range
The maximum and minimum values of the independent or dependent variables; important in ensuring that any pattern is detected. For example a range of distances may be quoted as either: 'From 10 cm to 50 cm' or 'From 50 cm to 10 cm'.
自变量或因变量的最大值和最小值。例如，间隔值域可以被引述为“从10公分到50公分”或“从50公分到10公分”。
Repeatable
A measurement is repeatable if the original experimenter repeats the investigation using same method and equipment and obtains the same results. Previously known as reliable.
假定原实验人员运用相同的办法和设备重复查询，并得到相同的成果，则测量是可重复的。之前被称为可靠的。
Reproducible
A measurement is reproducible if the investigation is repeated by another person, or by using different equipment or techniques, and the same results are obtained. Previously known as reliable.
假定由别人重复查询，或运用不一样的设备或技能却得到相同的成果，则测量是可重复的。之前被称为可靠的。
Resolution
This is the smallest change in the quantity being measured (input) of a measuring instrument that gives a perceptible change in the reading.
这是测量仪器被测量的量(输入量)中最小的改变，给读数带来了可发觉改变。
Sketch graph
A line graph, not necessarily on a grid, that shows the general shape of the relationship between two variables. It will not have any points plotted and although the axes should be labelled they may not be scaled.
闪现两个变量之间联络的一般形状折线图，图不必定在网格上。示意图上不会制造任何点，坐标轴大约被符号，但可以不会被缩放。
True value
This is the value that would be obtained in an ideal measurement.
这是有抱负测量环境中可以得到的值。
Uncertainty
The interval within which the true value can be expected to lie. Whenever a measurement is made, there will always be some uncertainty or doubt about the result obtained. Uncertainty can be expressed in terms of spread of values obtained. For example, a length of 56 cm ±2 cm would mean the true value could be anywhere between 54 cm and 58 cm.
估量与被测量的实践量值可以发生的误差的规模。不管啥时分进行测量，所得到的成果总会有一些不断定性。不断定度可以用得到值的分布来标明。例如，长度为56 cm±2 cm意味着真实值可以在54 cm到58 cm之间的任何数值。
Valid conclusion
A conclusion supported by valid data, obtained from an appropriate experimental design and based on sound reasoning.
经过恰当的实验方案和合理推理得到的有用数据所撑持的结论。
Variables
These are physical, chemical or biological quantities or characteristics.
物理、化学或生物的数量或特征。
Categoric
Categoric variables have values that are labels, eg names of plants or types of material.
阐明事物品种的称号，其取值是分类数据，如植物称号或材料类型。
Continuous
Continuous variables can have values (called a quantity) that can be given a magnitude either by counting (as in the case of the number of shrimp) or by measurement (eg light intensity,flow rate etc). Previously known as discrete variable.
接连变量可以稀有值(称为数量)，可以经过计数(如虾的数量)或测量(如光强度、流量等)给出数值巨细。早年称为离散变量。
Control
Control variable is one which may, in addition to the independent variable, affect the outcome of the investigation and therefore has to be kept constant or at least monitored.
控制变量是指除了自变量之外，还可以影响成果的变量，因而有必要坚持这些变量不变或至少进行监测。
Dependent
Dependent variable is the variable of which the value is measured for each and every change in the independent variable.
因变量是指对自变量的每一次改变需要测量其值的变量。
Independent
Independent variable is the variable for which values are changed or selected by the investigator.
自变量是查询者改动或选择值的变量。
