reactionformation,formation
请考过sat2化学的人进来回答下 几种基本反应的英文在考试中是怎么写的? 特别是置换反应和复分
combustion reaction燃烧,displacement reaction或single replacement reaction置换,double replacement reaction复分解,neutralization reaction中和,sythesis reaction化合(合成),formation reaction生成物系数是1的化合反应,addition reactions加成,decomposition reaction分解,oxidation-reduction reaction氧化还原。基本就这些了,sat2的书找不着了,这是从ap的书上抄的,已经超纲了应该不会更多了。
热力学 下标 c f r什么意思
热力学第一定律那章里面 f是反应 r是生成 c是燃烧 比如反应焓 标准摩尔生成焓 等
△fGm运算时要乘以系数吗?
其中G是Gibbs free energy,吉布斯自由能;f是formation,形成,生成;r是reaction,反应;m是mole,指一摩尔对应的量。
放在一起:前者是标准摩尔生成吉布斯自由能,后者是标准摩尔反应吉布斯自由能。计算某个物质“生成”的要求是,一个反应由标准状态下的稳定单质生成一摩尔标准状态下的该物质,产生的吉布斯自由能变。标准状态的定义是:
The standard state temperature is 25°C (298 K). It is possible to calculate standard state values for other temperatures. 温度是25摄氏度
All liquids are pure.液体是纯液体
The concentration of all solutions is 1 M (1 molar).溶液浓度为1摩尔每升
All gases are pure.气体是纯气体
All gases are at 1 atm pressure.气体在一个大气压下
按照这个定义可以计算标准摩尔生成G。
sublimation是什么意思
sublimation
[英][?s?bl?'me??n][美][?s?bl??me??n]
n.升华,升华物,高尚化;
例句:
1.
Sigmund freud referred to projection, sublimation, reaction formation, displacement-alltools of self-distancing from problems that touch the ego too profoundly.
弗洛伊德所述之种种投射,升华,反向形成,置换--这些全部都是当本我受到极大的触动后的自我隔离的方法。
谁能帮我翻译一下?
All-out acoustic logging includes the dissemination of time, energy, frequency and mode of transmission, and so rich in information, which can be a lot of reaction formation of the acoustic characteristics, and the formation of the acoustic characteristics of the formation and geological characteristics are closely related. At present, more information on each is measured out in the wave of P-wave, the S-wave and Stone wave propagation time, energy and frequency changes. Through multi-scale and slow in time-related analysis of different models of the wave when the scope and frequency bands. At the same time as a wavelet transform in time domain and frequency domain of the signals of local characteristics, it can be Shuangshu complex wavelet transform applied to the acoustic logging, the aim is through multi-scale wavelet analysis and waveform reconstruction, in different scales The whole wave of a filter to suppress noise and improve signal to noise ratio, isolated from each component wave, and better information from each component wave.
