双锥体

In normal group and sham lesion group, BDA positive neurons were distributed symmetrically in the pyramid cells of sensorimotor cortex, and BDA positive fibers of pyramid cells passed through the cerebral cortex, internal capsule, cerebral peduncle of midbrain, basilar portion of pons to the pyramid of medulla oblongata. At the lower part of the medulla oblongata, most of the BDA positive fibers passed through the pyramidal decussation to the contralateral side, continously descended at the ventral part of posterior funiculus just dorsal to the posterior gray commissure and ended at sacral spinal segments.

正常组和假损伤组大鼠BDA示踪显示BDA标记阳性细胞定位于双侧感觉运动皮层的锥体细胞，锥体细胞发出的BDA阳性纤维束对称分布于双侧皮层、内囊、大脑脚、脑桥基底部、延髓锥体中的皮质脊髓束内，继而经锥体交叉到脊髓后索，在双侧后索最深层、灰质后连合背侧下行至脊髓骶段。

Some SPR-LI neurons were also positive for TH. After administration of vasopressin, SPR-LI structures became denser, especially at levels of pyramidal decussation and area postrema . The dendrites of motor dorsal nucleus of X in the dorsal part of MVZ appeared thin and straight in morphology instead of curl and thick outlooks. These results implicate that some SPR-LI neurons might receive or regulate the cardiovascular stress information induced by vasopressin.③In PHA-L/FOS/TH triple-labeled experiments, seven kinds of immunohistochemical structures were found in MVZ. They were FOS-LI neurons, TH-LI neurons, PHA-L positive fibers, PHA-L positive fibers terminated on FOS-LI or TH-LI neurons, FOS/TH doublelabeled neurons, PHA-L positive fibers terminated on FOS/TH double-labeled neurons.

在锥体交叉和最后区水平，SPR免疫反应阳性结构较正常组明显增强；背内侧部迷走神经运动背核的SPR纤维也由弯曲的粗纤维变为细的直纤维，30％的SPR阳性神经元为SPR/FOS双标记神经元，提示这些神经元参与感受心血管伤害性刺激信息，继而参与心血管活动信息的中枢传导或整合；③三重标记研究结果显示，在MVZ可见到七种免疫反应阳性结构，即PHA-L，FOS，TH，FOS/TH，PHA-L/FOS，PHA-L/TH，PHA-L/FOS/TH。

The same results were observed in the brain of the unilateral pyramidotomy group above the level of the transection site. Below the level of the transection site, the BDA positive fibers were seen in the right pyramid of medulla oblongata and the left dorsal funiculus of spinal cord, but the BDA positive fibers in the left pyramid of medulla oblongata and the right dorsal funiculus of spinal cord were not seen.

锥体束横断损伤大鼠在损伤部位以上可见双侧对称的BDA阳性纤维束，损伤平面以下在右侧延髓锥体和左侧脊髓后索中见有BDA阳性纤维束，损伤侧锥体和右侧脊髓后索中未见有BDA阳性纤维束。

The barrel part of XLP/A Cyclone dust collector assume bicone. Among these, the upper of the dust insulator is orthostyle and the lower is spiral line style.

XLP/A型旋风除尘器的筒体部分为双锥体，灰尘隔离室的上段为直线型，下段为螺旋线型。

The study of structure shows that the noncrystalline network is composed of [PO_4] tetrahedron and [VO_5] trigoral bipyramid.

结构研究表明[PO_4]四面体及[VO_5]三角双锥体共同构成非晶态的网络骨架。

The people very are early realize CVT are facilitate driving, enhance the vehicles fuel oil efficient ideal installment, appears the bipyramid ball, the plate, the hooped column body from several dozens years ago and so on develops the leather belt transmission, but as a result of the rubbing surface friction coefficient and the components withstanding unit pressure limit, adds in the processing craft and the control difficult problem, cannot transmit compares the high efficiency, only limits uses in on the compact car.

人们很早就意识到CVT是方便驾驶、提高车辆燃油经济性的理想装置，由几十年前出现的双锥体球、盘、环柱体等发展到皮带传动，但由于摩擦面的摩擦系数及零件承受单位压力的限制，加之加工工艺和控制上的难题，不能传递较大功率，仅限用于微型汽车上。

The results indicates that the glass transition temperature T(subscript g increases, the intensity of exothermal peaks decrease, the thermal stability of the tellurite glass improves, and TeO3 trigonal pyramids transform into TeO4 trigonal bipyramid, when other metal oxides such as TiO2, BaO and WO3 were introduced and the content of TeO2 was fixed.

结果表明，在TiO2的含量一定时，引入其他金属氧化物TiO2、BaO和WO3，玻璃转变温度升高，放热峰强度减弱，碲酸盐玻璃的热稳定性提高。而Raman光谱表明，随着其他金属氧化物的引入，玻璃网络结构中的TeO3三角棱锥体向TeO4双三角锥体转化。

Results: nk 4r immunoreactivity was found extensively localized in neuronal somata and neurite of cerebral cortex, and mainy in layer ⅲ,ⅴ. double labeling experiments confirmed that 100% nk 4r immunoreactive neurons co expressed neun, but not gfap.

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。
