宽度平均值

The geometric mean of the half-peak width and the down time of the induced voltage was 0.87 and 2.9 μs, respectively.

感应电压的半峰值宽度和下降时间的几何平均值分别为0.87和2.9 μs。

Width: take 3 point in average to measure the width.

2.1.2 宽度检验：平均取三个点测量产品的宽度，取平均值记录在表格中

The results show that:①The mean length of Ligularia is the biggest, and the mean length of Ajania, Anaphalis and Artemisia is the smallest; the mean width of Aster and Ligularia is bigger than that of others; the mean length/width have lots of differences, the biggest being Senecio, and the smallest Artemisia.

①橐吾属连萼瘦果平均长度最大，亚菊属、香青属和蒿属连萼瘦果平均长度较小；紫菀属和橐吾属的平均宽度相对较大；长／宽的平均值在各属间相差很大，最大的为千里光属，蒿属最小。

The available operation range in clivus and anterior cranial base by transsphenoidal opproach was also observed during the operation under the help of neuronavigational pointer. Forty-one patients underwent sublabial, transseptal, transsphenoidal approach to the pituitary region guided by Surgical Microscope Navigation was studied. The piriform aperture was 27. 2mm±3. 1 , the origin of inferior nasal concha 30mm±4. 1, the origin of middle nasal concha 27. 9mm±4. 3. These data are important for transsphenoidal approach, because the piriform aperture and the origin of both inferior and middle nasal conchas restricted the opening width of the Hardy specula. If any distance of these bony structures was much less than the mean one, may cause inadequate opening of the specula blade and resulting dissatisfied operative field. Microadenomas or cystic tumors perhaps can be operated even in a narrow exposure, but large or giant solid adenomas may need a proper evaluation including changing the operative approach or performing a bilateral submucous inferior conchotomy or posterior ethmoidectomy firstly.

手术中还利用CT导航系统观察棒研究了经口—鼻蝶窦入路在斜坡区和前颅底能够达到的实际有效操作范围，为扩大经蝶窦入路手术在斜坡区和前颅底的应用奠定基础，在国内外尚未见同类报道。41例垂体瘤患者梨状孔平均宽度27.2mm±3.1，下鼻甲根部附着处间距30mm±4.1，中鼻甲根部附着处间距27.9mm±4.3，这是经口—鼻蝶窦入路手术中，对Hardy双瓣鼻窥器张开限制的主要骨性结构，若患者这些径线值明显小于平均值，则可能因为鼻窥器打开不充分而影响手术暴露，当然对于垂体微腺瘤和以囊变为主的垂体瘤可能影响不大，但对于大和巨大垂体瘤必须要有充分的准备，包括评估是否改用其他入路，或先行鼻甲切除再行经蝶手术。

Measure the width and length at three points on two ends and middle part of membrane by tapeline with an minimum scale of1mm, then calculate the area per roll membrane by multiplying mean length with mean width.

5.3 尺寸偏差Dimensional deviation 5.3.1 用最小分度值为1mm 的卷尺在卷材两端和中部三处测量宽度、长度，以长度的平均值乘以宽度的平均值得到每卷卷材的面积。

The pulse widths and spacings are arranged so that their weighted average produces a sine wave.

如此设置的脉冲宽度和间距使它的加权平均值恰好是正弦波。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
