So let's just calculate, given this small additional pressure, how high is the liquid going to go, above the level of the solution.
现在我们计算一下,对于这样一个小的多余的压强,液体相对于溶液的,液面能有多高。
They also said that the study subjects only moderately lowered their sodium intake, so the effect on blood pressure and heart disease was small.
他们还说,这项研究只是适度地减少了盐摄入量,所以,对于血压和心脏疾病影响很小。
The impact pressure on the steel is about 3,500 atmospheres. That is the weight of three small cars pressing on an area only a centimetre or so square.
作用在那块钢铁上的压强约为3500个大气压,相当于三辆小型汽车的重量压在一块1平方厘米左右的地方。
Let's say we start from some V1 and p1 here, so high pressure, small volume and we end up with a high volume low pressure, under constant temperature condition.
例如我们要从压强比较高,体积比较小V1,p1出发,到达低压强,大体积的末态,过程中温度不变。
