又到考试周，又开始监考。
1、张飞在世
考试刚刚开始，一考生竟然就开始左顾右盼打小抄，此时此刻，如闻一声惊雷：
“不好好考试，给我滚”，之间满脸络腮胡子的同事猛喝，好么，接下去的考试安安静静，规规矩矩。
2、谢谢老师
和同事监考，一学生交卷后居然朝同事亲切的说声谢谢，问同事原因，同事说，我抓了半天想抓现行，就是没抓到，还TM谢谢我？
3、新科技
为了抄，同学们八仙过海各显神通。一次监考，居然发现会变颜色的橡皮，写好答案，手握出字，不握和普通橡皮一模一样，谁说我国材料工业不发达，后来上wiki也没发现神秘材料有如此神通。
4、饮料瓶
上有高科技，下有神奇方法，以学生居然在饮料瓶标贴后面写满答案，对光一看，答案！

Sensory analysis

Sensory analysis

Sensory analysis (or sensory evaluation) is a scientific discipline that applies principles of experimental design and statistical analysis to the use of human senses (sight, smell, taste, touch and hearing) for the purposes of evaluating consumer products. The discipline requires panels of human assessors, on whom the products are tested, and recording the responses made by them. By applying statistical techniques to the results it is possible to make inferences and insights about the products under test. Most large consumer goods companies have departments dedicated to sensory analysis.

Sensory analysis can generally be broken down into three sub-sections:

* Effective testing (dealing with objective facts about products)
* Affective testing (dealing with subjective facts such as preferences)
* Perception (the biochemical and psychological aspects of sensation)
Effective testing

This type of testing is concerned with obtaining objective facts about products. This could range from basic discrimination testing (e.g. Do two or more products differ from each other?) to descriptive profiling (e.g. What are the characteristics of two or more products?). The type of panel required for this type of testing would normally be a trained panel.

Affective testing

Otherwise known as consumer testing, this type of testing is concerned with obtaining subjective data, or how well products are likely to be accepted. Usually large (50 or more) panels of untrained personnel are recruited for this type of testing, although smaller focus groups can be utilised to gain insights into products. The range of testing can vary from simple comparative testing (e.g. Which do you prefer, A or B?) to structured questioning regarding the magnitude of acceptance of individual characteristics (e.g. Please rate the “fruity aroma”: dislike|neither|like).

Perception

Perception involves the biochemical and psychological theories relating to human (and animal) sensations. By understanding the mechanisms involved it may be possible to explain why certain characteristics are preferred over others.

Descriptive analysis involves trained panels (6-30 people) who evaluate products by rating the intensity of various characteristics on a scale. Statistical analyses are applied to look for differences among various products for characteristics of interest.

Consumer testing (sometimes called ‘hedonic testing’) involves having potential consumers of a product evaluate various products and a small number of items on a ballot.
