Gastaldi领导的小组在结合利用X射线形貌术以及相位敏感成像术研究Al-Pd-Mn二十面体准晶单晶中的缺陷时发现两种衬度，其中已知黑白双瓣衬度是由于准晶中的五角十二面体空洞引起，而对于环形衬度则除了知道退火行为不同于位错从而不太可能是位错圈外，基本上对其缺陷的几何及性质不甚了解。

While disease had thus become an inhabitant of Lowood, and death its frequent visitor; while there was gloom and fear within its walls; while its rooms and passages steamed with hospital smells, the drug and the pastille striving vainly to overcome the effluvia of mortality, that bright May shone unclouded over the bold hills and beautiful woodland out of doors.

回顾性分析32例全腔静脉肺动脉连接术患者的临床资料：年龄5～24岁，平均（10±5）岁，体重13～55 kg，平均（28±11） kg，病种包括单心室16例，右心室双出口并完全性心内膜垫缺损6例，完全性大动脉转位并完全性心内膜垫缺损3例，三尖瓣闭锁6例，二尖瓣闭锁1例。其中，在低温体外循环心脏停跳下18例行右房内侧隧道法，1例行心外管道法，常温体外循环心脏跳动下10例行心外管道法，非体外循环下2例行心外管道法，1例行分次全腔静脉肺动脉连接术。

Purpose: To quantify mitral valve area in mixed mitral valve lesions and combined with aortic valve lesions.

目的∶探讨二尖瓣双病变和联合瓣膜病变二尖瓣口面积的准确测定方法。

Objective To introduce a procedure of nympholepsy.Methods With the central part of the nympha excised,the hem preserved,the superior and lower part of the nympha served as flap pedicles,a double pedi-cles arc-shaped flap was elevated.The incision was conglutinated by ZT glue after the muscular layer sutured.Re-sults 36cases（62sides）were cured by this method with satisfying results.

目的 介绍治疗小阴唇肥的手术方法方法采用弧形双蒂瓣法行小阴唇整形术，保留小阴唇边缘，以小阴唇上、下部蒂，去除小阴唇中部一全层组织，形成一弧形双蒂组织瓣，缝合肌层后用医用粘涂ZT胶粘合切口。

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。

For precision azimuth, as in gunfire control, a double-lobe pattern (figure 3) can give great directional precision by finding the direction in which the echo "pips" for both lobes are of equal heights. This is called "lobing".

当需要精确的方位角，如指挥火炮时采用双波瓣发射，两波瓣回迹强度相等时便可获得精确的目标方位角，这被成为&波瓣法&。
