前桥

In this paper, a BUCK circuit added lead before the full bridge which used in BLDCM drive system is proposed, and this drive system is studied.

在永磁无刷直流电机驱动系统中，本文提出在传统的三相桥前加上BUCK电路，用于永磁无刷直流电机的驱动，并就系统进行了理论分析与实验研究。

FasL immunopositive neurons were observed in cerebral cortex, especially in pyramidal neurons of lamina Ⅱ and Ⅴ, cerebellar nuclei, diencephalon, and brain stem nuclei involving pontine nucleus, vestibular nucleus, cochlear nucleus, spinal nucleus of trigeminal nerve, hypoglossal nucleus, nucleus ambiguous and reticular formation.

间脑中有FasL阳性神经元分布。在脑干，Fas主要分布于前庭神经核、迷走神经背核和三叉神经脊束核的神经元；FasL广泛分布在脑桥核、前庭神经核、三叉神经脊束核、舌下神经核、蜗神经核、网状结构和疑核。

Neuronal cell bodies and fibers with moderate mGluR7-LI were seen in the olfactory bulb,anterior olfactory nucleus,piriform cortex,septofimbrial nucleus,bed nucleus of the strial terminalis,lateral hypothalamic area,paraventricular hypothalamic nucleus,supramammillary nucleus,medial and lateral mammillary nuclei,most part of the thalamus,medial and lateral geniculate bodies,nucleus of the optic tract,red nucleus,substantia nigra,interpeduncular nucleus,pontine nuclei,lateral parabrachial nucleus,superior olivary complex,nucleus of the trapezoid body,motor nucleus of the trigeminal nerve,facial nucleus,ambiguus nucleus,cochlear nucleus,vestibular nuclei,nucleus of the solitary tract,hypoglossal nucleus,prepositus hypoglossal nucleus,medullary reticular formation,Purkinje cells of the cerebellum,nucleus raphe obscurus,intermediolateral nucleus of the spinal cord,Onuf′s nucleus and lamina X of the spinal cord.

呈中等强度染色的神经元胞体和纤维见于嗅结节、前嗅核、梨状皮质、隔伞核、终纹床核、下丘脑外侧区、下丘脑室旁核、乳头体上核、乳头体内、外核、丘脑大部分核团、内外侧膝状体、视束核、红核、黑质、脚间核、桥核、臂旁外侧核、上橄榄复合体、斜方体核、三叉神经运动核、面神经核、疑核、耳蜗核、前庭核簇、楔束外核、孤束核、舌下神经核、舌下神经前置核、中缝隐核、延髓网状结构、小脑蒲肯野细胞层、脊髓中间带外侧核、Onuf核和中央管周围灰质。

Results showed that after injection of HRP into medial recteus subnucleus of oculomotor nucleus,HRP labelled cells were found in contralateral abducens nucleus and also in vestibular nucleus and pontine ...

结果表明：注射HRP于大鼠动眼神经核内直肌亚核后，在对侧展神经核区以及前庭神经核、脑桥旁正中网状结构中发现HRP单标记细胞；在前庭神经核内，可见HRP单标记、GABA阳性和HRP/GABA双标记三类神经元，其中HRP/GABA双标记细胞占HRP标记细胞总数的47.1%。

Comclusion: transpetrous presigmoid retrolabrinth approach was rational approach for surgery on petroclivus and -4- CPA; it抯 important for accomplish the surgery to study and master the anatomy and variance of this approach; there was relative anatomical relationship among those structure on posterior of petrous bone; AAMP was the extracranial mark of inflexion of TS and SS; LAM and PSC were obvious bone marks for operation; we can confirm the abraded range of petrous bone lean upon LAM and/or GSS beside abrading step by step as literature, and it抯 unnecessary and unrational to emphasize to show PSC if the surgical space was enough; preceding sigmoid sinus and high jugular bulb often appeared at right and would bring disadvantage effect; interspace ,between CN V and CNVII or CNVII and CNJXI, were available to reach clivus and manage the mass on the range.

经SS前迷路后入路是处理岩斜坡区、桥小脑角区病变理想的手术入路；研究和熟悉手术入路中的解剖结构及部分变异对指导手术十分必要；岩骨内测面的骨性结构之间有着相对稳定的空间关系；顶乳缝前角是SS和TS转接处在颅外的标志；IAM和PSC等结构可以作为手术中的重要骨性标志；以PSC确定岩骨的磨除范围是较安全和可靠的，但亦可以结合影像检查，以内耳道和乙状窦前缘为基点判定切除范围，如果操作空间足够，过分强调磨出半规管是不适当的；右侧GSS的宽度和深度较对侧大，SS前置和颈静脉球高位较对侧多见，这些都对右侧入路有不利的影响，但仍可以进行手术操作；三叉神经和面神经间隙及面l 神经和舌咽神经间隙方便到达斜坡并处理病变。l

The sciatic nerve can be regarded as the optimum bridging nerve. The double C7 nerve waved into beam through the prespinal route can be selected as transfer nerve. It is feasible to identify and anastomose the L1-L4 anterior lumbar spinal nerves at the L1 level.

坐骨神经可选择为颈7神经移位重建截瘫下肢功能的桥接神经，双侧C7神经可经椎体前通路编织成束作为动力神经源，在L1阶段椎管内吻合L(下标 1~4)腰神经前根的具有可行性。

I have been to Ancient Bridge Gate, fountain in Heracles and the market in front of Holy Spirit Hall, all of which are in those quiet black-and-white photographs in the interleaves, and I have taken the breath of peace and clarity of Heidelberg's winter. What new feelings will these lives half-century before bring me?

插页里那些安静的黑白照片，老桥门、赫拉克勒斯的喷泉、圣灵堂前的市集，我都已到过，我呼吸到海德堡冬日的宁静与清澈，这些半个世纪前的生活，会带给我哪些的新感受？

The coal, who was a hot-headed fellow, stepped brashly onto the newly constructed bridge, but when he got to the middle and heard the water rushing beneath him, he took fright, stopped, and did not dare to go any further.

煤块性子比较急，立刻大着胆子走上了这座刚刚搭好的桥。可是它走到桥中间时，听到溪水在脚下哗哗地流淌，不由得害怕起来，站在那里不敢往前走。

In summer, he metamorphoses himself into a frog; and in the evening, when night is falling, in front of the bridges of Austerlitz and Jena, from the tops of coal wagons, and the washerwomen's boats, he hurls himself headlong into the Seine, and into all possible infractions of the laws of modesty and of the police.

到了夏季，他转化为青蛙，当夕阳西沉黑夜将临时，在奥斯特里茨桥和耶拿桥前，他从成队的煤炭船顶上和洗衣女工的船头上，低着脑袋跳到塞纳河里，所有礼貌和警章全违犯了。

CHAPTER VIII IN WHICH THE READER WILL FIND A CHARMING SAYING OF THE LAST KING Chinese In summer, he metamorphoses himself into a frog; and in the evening, when night is falling, in front of the bridges of Austerlitz and Jena, from the tops of coal wagons, and the washerwomen's boats, he hurls himself headlong into the Seine, and into all possible infractions of the laws of modesty and of the police.

八 最后一个国王的一句妙语英文到了夏季，他转化为青蛙，当夕阳西沉黑夜将临时，在奥斯特里茨桥和耶拿桥前，他从成队的煤炭船顶上和洗衣女工的船头上，低着脑袋跳到塞纳河里，所有礼貌和警章全违犯了。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
