18. numeral

noun

a word, letter, symbol, or figure, etc., expressing a number; number:

the Roman numerals

Number、Numeral 、Digit和Figure

Number、numeral、digit和figure都和数字有关，有的人把它们当作同义词来用，但事实上它们含义并不一样。那么具体区别是什么呢？Number、Numeral wbr、Digit和Figure区别X Number是个抽象的数量概念（idea），看不见摸不着。其表达形式（token/sign/symbol/name/mark/figure）用来计数（counting）和测量（measurement），则可以看得到。通常用numeral来表达number，当然还可以用手势、声音等其它方式。

Numeral是代表（represent）数量概念的符号，有不同的书写体系（writing system），例如罗马数字（Roman numerals）【numeral XVII代表17】和印度阿拉伯数字（Hind-Arabic numerals）【即阿拉伯数字】。简单说，numeral就是把number写出来的方法。例如，三的抽象数量概念（threeness）可以具体表达为‘three’、‘3’、‘III’、‘11’【二进制（binary）】、‘三’和其它形式。Numeral广义上指任何代表数字的符号，但狭义上就指阿拉伯数字。

Digit是用来表达numeral的单独符号（single symbol）。日常生活中用0、1、2、3、4、5、6、7、8与9十个digit来表达number。例如，numeral 153由三个digit【1、5和3】来组成；numeral 9由一个digit【9】组成。

所以，digit组成numeral，而numeral代表number。可以用单词和字母来打比方。Letter组成word，而word代表idea。例如，dog有三个字母【d、o和g】组成，而dog表达‘狗’的概念。也可以用人和名字打比方，number类似一个人，而numeral则是他的名字；名字并不是人 ，但代表那个人。一个人可能有几个名字【学名、小名、外号、英文名】，但都指同一个人。

严格地讲，特指数字符号时用numeral或figure；特指单个数字时用digit；其它情况则用number。日常用语无须如此计较number和numeral的区别，通常可以用number来代替numeral。

Number 在日常使用中既可指文字形式也可指数字形式的数量概念，所以如果强调文字形式用spell out或word；反之则用figure、digit或numeral。而write out则似乎两者皆可。Number、Numeral wbr、Digit和Figure区别例如：

l The small numbers, such as whole numbers smaller than ten, should be spelled out.

l Some experts say that any one-word number should be written out.

l Two-word numbers should be expressed in figures.

l With everyday writing and recipes you can use digits, like “4% of the children” or “Add 2 cups of brown rice.”

l You should use numerals, not words, when the number is a key value, an exact measurement value, or both. For example, in the sentence “Our computer backup system uses 4 mm tape” the numeral is in order.

l Rounded numbers over a million are written as a numeral plus a word. Use “About 400 million people speak Spanish natively,” instead of “About 400,000,000 people speak Spanish natively.” If you’re using the exact number, you’d write it out, of course.【这里write out 应该指用数字表示准确数量，而非文字】Number、Numeral wbr、Digit和Figure区别

19. combustion

the act or process of burning.

Chemistry

rapid oxidation accompanied by heat and, usually, light.

chemical combination attended by production of heat and light.

slow oxidation not accompanied by high temperature and light.

If combustion occurs within a battery, says Boeing, it would be snuffed out in a microsecond for lack of oxygen.

20. genome

a full set of chromosomes; all the inheritable traits of an organism.

In modern molecular biology and genetics, a genome is the genetic material of an organism. It consists of DNA (or RNA in RNA viruses).

The scientists tracked the words in the "Iliad" the way they would track genes in a genome.

Review

   This article，without too much new words, still confuses me a lot when I read it through for the first time. For one reason, limited knowledge of the scientific fields such as physics and chemistry blocks my understanding of the details, which affects the overall comprehension of the text. However, the titles ahead of each part gives me a hand in grasping the main idea of each  part. In other words, I could march on in a more logical  way.
