利用声波方程建立井间波场数值模拟计算公式，选取一对实际井的声波测井资料建立了速度模型，进行井间数值模拟，得到了合成记录，对记录波场进行分析，能够清楚地观察到上，下行反射波和直达波的时距特征。

The unblinded nature of the study, unavoidable as it was, could have led to treatment bias if clinicians took unusually good care of subjects in the dietary group, leading to a delay in need for dialysis, or, if the decision to switch someone from the diet to the dialysis group was delayed in order to make the diet appear more effective than it really was.

研究本身不可避免选取非盲法导致了治疗的偏向，临床医师在饮食治疗组中总是比较好地照顾患者带来了透析需要的延迟或者从饮食转为其他透析治疗的延迟，从而使得饮食疗法似乎比起其实际结果更为有效。

On the basis of the existing sieving method of sieving thyratrons, serving the typical fuze detonating circuit as the circuit of sieving thyratrons, and applying the operation conditions of the typical fuze detonating circuit in the sieving circuit, we can measure more accurately the turn on voltage, trigger voltage, turn on time, and leak of electricity of the thyratrons.

在现有闸流管检测方法的基础上，将实际的引信起爆电路作为闸流管的检测电路，将起爆电路的工作条件施加于检验电路，可以更准确地给出闸流管的导通电压、触发电压，同时测量出闸流管的导通时间以及闸流管在关断状态下的漏电流。

However, the intrinsic CMR can be observed only at a high magnetic field (~ several Teslas) and in a narrow temperature window near Curie temperature, which is not appealing for practical application.

但是，CMR效应只有在较高的外加磁场和较窄的温度范围内才能观察到，这极大地限制了它的实际应用。
