原题(英文)当中是让求氮气、氧气和“其它气体”这三种气体的分压,不是求氩、二氧化碳和氖的分压强.
氮气的分压强:101.3kPa×78.08%=79.095kPa
氧气的分压强:101.3kPa×20.95%=21.22kPa
其他气体的分压强:101.3kPa×0.97%=0.98kPa

Sushi is a kind of food made with a mixture of cooked or raw
Sushi is a kind of food made with a mixture of cooked or raw fish, vegetables, and rice. Although Sushi is most commonly considered to have its origin in Japan, it actually began in China during the 7 th Century.
At that time, any fish caught had to be preserved. Raw fish was cleaned and then pressed between layers of heavy salt. After a couple of months, the whole process was complete. Over time, a discovery was made that by rolling the fish in rice that had been soaked in vinegar the fish was easily fermented (发酵) in a few days rather than months. The rice was then thrown away and the fish was eaten. However, with a food shortage, people began consuming the rice as well as the fish and thus, Sushi today as we know was born. However, in the 1800s, a famous chef by the name of Yohei created two styles of Sushi—one called Edo, and the second, Osaka, for two cities.
Sushi is usually consumed with hot green tea. Also, Gari is offered free and eaten between bites to create a better taste. Two kinds of sauce are usually available: one is soy sauce, which is poured on most kinds of Sushi; the other is a thick sweet sauce used on eel (鳗鱼).
Sushi has taken the world by storm and today is a multi-billion dollar industry. Its popularity continues to rise because people are looking for healthy food that is quick and easy to make. With such unbelievable popularity as well as the health benefits of eating Sushi, it is likely that this food will continue to be a part of everyday life for many more centuries to come.
小题1:Two kinds of Sushi, Edo and Osaka, were probably named after _______.
A.the chef’s name B.their birthplaces
C.the name of fish D.some kinds of food
小题2:When people eat Sushi, Gari is used to _______.
A.keep Sushi last long
B.make green tea better
C.digest Sushi more quickly
D.make Sushi more delicious
小题3:Why do people like Sushi today?
A.It is cheap and delicious.
B.It is served with free Gari.
C.It is beneficial to people’s health.
D.It is easy to be kept for a long time.
小题4:What can be the best title for the text?
A.Delicious Sushi and Its Origin
B.How to Make Delicious Sushi
C.Yohei and Two Styles of Sushi
D.The Birthplace of Sushi—China

这是个名词,意思是 羟基磷灰石不满的混合物 这是一种化学物质
羟基磷灰石填料广泛用于核酸和蛋白的纯化,酸性和中性蛋白能被填料的钙离子吸附,盐不影响吸附和洗脱,这样的蛋白需要用用低浓度(30-120mM)的pH7.0的磷酸盐缓冲液洗脱.碱性蛋白被磷酸根吸附,盐会影响吸附和洗脱,所以洗脱可以用盐或者高浓度(120-500mM)的pH7.0磷酸盐缓冲液洗脱.
:羟基磷灰石因陶瓷化工艺不同分为2种类型:I型和II型,I型对蛋白质具有更大的保留,对普通蛋白质具有更大的动态载量,主要纯化大部分蛋白质(分子量一般在100kd一下);II型由于孔径较I型大,因而对抗体和部分重组疫苗等大分子量蛋白质的动态载量更高,而对HSA几乎无保留,因而更适合于抗体的纯化,同时II型对核酸具有更大的保留,能够分辩单、双链、是否超螺旋等各种高级结构的核酸,因而也适合纯化核酸.

admixture 和mixture 同为名词,都可以指混合物,也可以泛指混合某种物体的过程.
但从牛津高阶英英字典的解释看来:admixture更加强调混合物在混合前的状态 "something mixed with something else",并可特别指小剂量的混合物;而mixture则强调混合物在混合后的整体 "a combination of different things"
我们建议同学在学习此类同类名词时多查英英字典,才能区分它们之间细微的差别 :)

在英语里,我们常会碰到这种现象,由于所用的介词不同,其语意也就变得大不相同.例如,consist in表示"在于…"之意;consist of则表示"包含","由…组成"之意.前者说明一样事物的性质,这种性质大都是抽象的、非物质的;后者则说明组成某一事物的部分,这些部分大都是具体的、物质的.此题为非谓语做后置定语,无被动,所以选consisting of

1,every time the fuel system delivers air fuel mixture to a cylinder,the ignition system follows up by delivering an electric spark,this ignites the mixture which creates the high pressure that move the pistons and turn the car wheels,the action is repeated many times each second while the engine is running.,
2,the internal combustion engine is a device used to convert the chemical energy of the fuel into heat energy,and then to convert this heat energy into usable mechanical energy,this is achieved by combining the appropriate amounts of air and fuel,and burning the mixture in an enclosed cylinder at a controlled rate ,a movable piston in the cylinder is forced down by the expanding gases of combustion
3,the efficiency of the internal combustion,reciprocating piston engine in converting the potential energy in fuel into mechanical energy is only about 33%,of the available heat energy in the fuel,about one-third is lost through the exhaust system and one-third is absorbed and dissipated by the cooling system,of the remaining one-thrid,about one-half is lost through available at the vehicles drive wheels
4,To start the engine,some method of cranking the engine is required to turn the crankshaft and cause piston movement,this is done by the starter motor when the ignition key is the start position,when sufficient air fuel mixture has entered the cylinders and is ignited,the power strikes create enough energy to continue crankshaft rotation,at the point ,ignition key is released to the run position and the starter is disengaged

1. 每次燃油系统输送燃油和空气的混合物到气缸里面,紧接着点火系统提供电火花.这样就可以点燃空气和燃油的混合物,从而产生强大的压力来使活塞运动以便推动车轮运转.只要在引擎点燃的情况下这个动作每秒钟会重复很多次.
