1·Objective. To report the reversible change of an intramedullary high-signal lesion on T2-weighted MRI as a presyrinx state.

目的：报道被看作是空洞前状态的MRI T2加权像的髓内高损伤信号的可逆变化。

2·With continuation of temperature cycling there is a reversible change of the shape(along curve 2) with a very small hysteresis.

在随后的温度循环中， 其形状的变化是可逆的（沿曲线2），滞后效果很小。

3·As General Petraeus himself admits, and our briefing this week argues, the change is fragile, and reversible (see article).

虽然彼德雷乌斯将军承认，我们本周的简报也同样认为，这种改变是脆弱并且可逆的。

4·It's reversible. It's a temperature change.

是可逆的，温度是变化的。

5·The permeability change is a reversible course.

其通透性的变化为一个可逆的过程。

6·During the cycle experiment, the films exhibited reversible two-color (yellow at oxidation and green at reduction) with a maximum transmittance change of around 30%.

循环实验中，薄膜呈现黄色到绿色的可逆变化，最大的透射率变化达到30%左右；

7·Conclusions the combine use of the high MI ultrasound and the high dosage of the ultrasound contrast agent can enhance the permeability of the BBB, but this change is reversible.

结论高机械指数的体表超声辅以高剂量超声造影剂在经颅脑超声造影中可导致血脑屏障通透性增加，但在造影检查后，这种改变可自行恢复。

8·In order to approach the carnot efficiency the processes involved in the heat engine cycle must be reversible and involve no change in entropy.

为了接近卡诺效率，所涉及的过程，在热机循环必须可逆且涉及没有改变熵。

9·The conformational change of the enzyme induced by organic solvents was a dynamic process and was reversible to some extent.

这种构象变化是一动态过程，且具有一定的可逆性。
