The superficial laminae of the spinal dorsal horn, especially lamina II which is composed mainly of small interneurons, receive primary afferent C fibers which transmit peripheral noxious information, and descending projection fibers from central endogenous antinociceptive system.

脊髓背角浅层，尤其是Ⅱ层是接受无髓和薄髓初级传入纤维传递的外周伤害性信息及来自中枢内源性痛抑制系统投射纤维传递的痛抑制信息的主要部位，胶状质主要由局部环路神经元构成。

As to the remaining parameters, two methods are developed: first, accepting that the projection function complies with a circular function within at least a part of a given field of view, constrained by the obtained object-to-image radial mapping and a constant focal length, the best-fitting point of the optical origin is tested along the optical axis; secondly, referring to the postulation of the exclusively bilateral mapping between an imaged point and its scenic sight ray, a measuring technique is developed to survey the world coordinates which will fabricate a projecting path to the imaged points located on the imageable region of the image plane in order to directly model the projection geometries involved.

而针对其余参数本文提出两种解题方法：其一是根据『在「部分视野角范围」内，鱼眼相机的投射模型符合一典型的「圆形函数」』以标靶实体与其影像尺寸为限制条件，测试光学轴上的最佳视觉参考点、鉴定最适当的投射模型、焦距、及有效的视野角度范围。其二是根据『一视野线排他性地与对应「呈影点」一一映射』参考一呈影点来搜寻空间中对应视野线的绝对座标后，据以演绎相机内部影像形成的模型。

A tungsten halogen lamp and a projecting lens are used to generate the collimated light. A CCD detector is used as light spot position sensor to measure the changes of the spot position at the rear focal plane of the imaging lens, and the optical angular deviation can be derived.

采用钨灯和投射透镜产生准直白光，用CCD探测器作为光斑位置传感器在成像透镜的后焦面测量光斑位置的变化，从而可得光学角偏差。

It is thought that there's an independent neural pathway through which itch is transferred mainly by peripheral unmyelinated C fibers to the most superficial part of dorsal horn, then the lamina Ⅰ spinothalamic tract ascends to the thalami and further projects to the cortex.

目前认为存在独立的痒觉神经传导通路，主要由外周无髓C纤维传入信号至脊髓背侧角的最浅层，Lamina Ⅰ脊髓丘脑束上行至丘脑，进一步投射至皮质区。

From 136 to 138, the expres- sion retrieved ventrally and expressed at the ventral half of the central tube (137) and the ventral horn especially in motor neurons (E7 and E8). Thus, the dorsal terminating axons relating to nociception and thermore?

到民至 Es麻Sema 3A的mRN的表达向腹侧撤退，主要在脊髓中央管周围的腹侧和前角运动神经元，这样使背侧投射性的痛温觉神经元轴突仅进入脊髓后角第 I、11层而不进一步向腹侧投射。

The P-wave velocity v(superscript p and electrical conductivity of chloritic amphibolite are measured at 1.0 GPa, from room temperature to 700℃, using ultrasonic reflection-transmission combined method and impedance spectra method respectively. The sample comes from northern margin of the North China craton.

在1.0 GPa、室温至700℃条件下，分别采用超声波反射－投射法和阻抗谱法，测量了华北克拉通北缘绿泥石化斜长角闪岩的弹性波纵波速度和电导率。

Our observation indicates that capsaicin as a nociceptive chemical irritant can selectively activate primary afferent C-fibers to release SP and Glu from their central terminals in the superficial dorsal horn. It seems that the release of SP and Glu acting on NK-1 and NMDA receptors results secondarily in the activation of dorsal horn neurons, transmitting nociceptive information to supraspinal structures.

以上结果表明辣椒素作为一种伤害性的刺激源，可选择性兴奋C类传入纤维，引起其分布于脊髓背角浅层内的末梢大量释放SP和Glu，通过相应受体兴奋背角伤害性感受神经元，包括上行脊-丘束投射神经元，将痛觉信息传递至脑。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
