结果低机械指数谐波超声造影对恶性病变诊断的的敏感性、特异性和准确性分别为96%、90.7%和93.8%。

Results The sensitivity, specificity and accuracy of diagnosing malignant liver tumors by contrast-enhanced harmonic ultrasonography with low mechanical index were 96%? 90.7%? 93.8% respectively.

在相同采样方法条件下，用不同量的甲醛吸收液测定空气中二氧化硫，吸收液量大，测定结果低，适当减少采样时的吸收液量，能提高监测数据的准确性。

At same sampling condition the large volume of absorbent solution will decrease the value of absorption and lower results of concentration sulfur dioxide in air.

s But it just turns out that the 4 s is so low in energy that it actually surpasses the 3 d, because we know the 3 d is going to be pretty high in terms of the three shell, and the 4 s is going to be the lowest interms of the 4 shell, and it turns out that we need to fill up the 4 s 4s before we fill in the 3 d.

但是结果是,能量较低,4s是第四层最低的，因为我们知道3d在第三层,是非常高的，4s是第四层,最低的，结果是我们在填充3d之前,需要先填充。

So in this experiment here, delta p is less than zero. You need to have this whole thing greater than zero. So delta T is less than zero as well. So if you're below the inversion temperature and you do the Joule-Thomson experiment, you're going to end up with something that's colder on this side than that side.

所以在这个实验中，Δp小于零,这全部都大于零,因此ΔT也小于零,所以如果在低于转变,温度的情况下做焦耳-汤姆孙实验,最后的结果是,这边的温度比这边低。
