Mr Olken calculates that on average 28% of reportedspending went missing, mostly because roadbuilders skimped on materials. Notall of the gap can be put down to venality, though: some of the gravel, forexample, was probably worn away.

他算了一下：平均有28%的花费，不见了踪影，主要原因是道路建筑商偷工减料（当然，并不是所有的差值，都可以归因为腐败：譬如，有一些砂石可能会有损耗。

Methods:We selected a group of 164 healthy volunteers and MRI scan in lumbosacral spine was performed for everyone.We obtained some measurements on MR workstation after exams such as: Antero-posterior diameter of the epidural fat located ventrally and dorsally to the dural sac of S_1 to S_5 level.We obtained mean distances and standard deviation s of all the values and then made a conclusion.

选择164例正常成年人(平均年龄41.4岁)行腰骶椎磁共振扫描，分别测量骶椎各水平前、后硬膜外脂肪的厚度，获得均数及标准差，并以性别、年龄及体重指数分组，进行组间比较及相关因素分析。

The results show that the measuring range for DIC is between 0 and 72μm, the mean measuring resolution is about 23. 74nm; for inputting image with video camera and scanner, the relative measuring resolution is 0.3μm and 0.1μm respectively.

分析表明，采用本文创建的微差干涉法测量离面位移，测量范围为（0～72μm），平均测量精度为23.74nm；对摄像机输入图象和扫描仪输入图象，采用特征点法测量面内位移的精度分别为0.3μm和0.1μm。

Results Mitral valve dilatation resulted in a decrease in left atrail diameter from (44±6)mm, a decline in transmitral valve pressure gradient from (18.2±6.8)mm?Hg to (7.2±3.8)mm?Hg, and an increase in mitral valve area from (1.04±0.21)cm2 to (1.98±0.55)cm2. 8 cases of severe restenesis developed.
