Winter by means of radioimmunology and in situ hybridazation to probe into the modulation mechanisms of kidney responsing to the winter, and observed effects of pinealectomy. The results show that there are seasonal changes in the level of MT in the Pineal body, serum, hyperthalamus-pituitary-gonadal axis and the same of the third courier---c-fos and the c-jun mRNA expressions in the hyperthalamus-pituitary-gonadal axis from the Summer to the Winter.

首次通过实验，观察了雄性SD大鼠在生理状态下松果体、血清、下丘脑-垂体-睾丸轴褪黑素含量的冬夏变化，下丘脑-垂体-睾丸轴第三信使（c-fos和c-jun）mRNA表达的冬夏变化以及摘除松果体对上述各项指标冬夏变化的影响，实验结果表明，松果体、血清、下丘脑-垂体-睾丸轴褪黑素含量以及下丘脑-垂体-睾丸轴第三信使（c-fos和c-jun）mRNA表达都存在明显的季节性变化。

It simulation results proves that when the inner pipes in the concentric annulus pipes stand still, the turbulent flow nucleus area approaches inner pipes; and when inner pipes circumvolve, the turbulent flow nucleus area approaches outer pipes. The shearing velocity near the inner pipes is the biggest, and the shearing velocity increases with the velocity of the inner pipes increasing.

模拟结果表明：在同心环空管道中当内管静止时，紊流核心区即轴向速度最大值区域靠近内管壁；当内管旋转时，紊流核心区即轴向速度最大值区域靠近外管壁；靠近内管壁处的切向速度最大，且随着内管转速的增加切向速度增大。

Based on the stress analysis to spired axis mechanism,in the aspect of sliding part which smoothes through alveolus intersection, theresearch of parameters optimization, about the middle alveolus of spired axis andthe dimension of sliding part, has been studied. To the problem that the reverseportion at the both sides of spired axis lashed fiercely and fraies quickly, thearticle finely analyses the best curve of alveolus when adding cushiony spring atthe both sides.

在对螺旋轴机构进行受力分析的基础上，从滑块顺利通过齿槽交叉点的要求方面，对螺旋轴中间段齿槽和滑块的尺寸进行了参数优化分析；针对螺旋轴两端曲线齿槽反向段在高速工作时冲击大、磨损快的问题；从减少滑块在齿槽反向段运动的冲击方面，比较分析了圆弧、抛物线、三角函数等曲线作为螺旋轴齿槽反向段曲线的加速度，提出了较优的(来源：ABCab论bf文网www.abclunwen.com)反向段曲线。

According to the characteristics of the larger start electric curent, start torque and the demagnetizing influence of the armature reaction of motereycle starter at the moment of starting, the formula of the largest demagnetizing magnetic- power is deduced and the magnetic method of separehng alnico is gnined on the basis of the largest dernagntizing magntic - power.

根据摩托车起动电机起动电流大、起动转矩要求高的特点，以及起动时直轴电枢反应和交轴电枢反应对永久磁铁的去磁作用，推导出最大去磁磁势的计算公式，给出了根据最大去磁磁势选择磁钢的方法，并通过实测证明电枢反应对起动电机性能的影响。

At the same time,a tension stress is applied on theγ′phase interfaces along the direction parallel to the stress axis,which results in the lattice expansion ofγ′phase to trap the Al,Ta atoms with the bigger radius.This brings out the accumulation of the solute atoms to form the N-type rafted structure.Al,Ta atoms with bigger radius diffuse to the {100} plane to form the linked bond of the heterogeneous atoms and the stable stacking mode,this is a main reason of promoting the transformation ofγ′phase into the N-type rafted structure.And the change of the strain energy density in different interfaces of the cubical-likeγ′phase is thought to be the driving force of the elements diffusion and theγ′phase directional growth during creep.

拉伸蠕变期间，类立方γ\'相中与施加应力轴垂直的界面受水平切应力，使晶格收缩可排斥较大半径的Al、Ta原子；与应力轴平行的界面受拉伸张应力，使晶格扩张可诱捕较大半径的Al、Ta原子，由此引起的原子偏聚形成γ\'相是自由能降低的过程；其中，较大半径的Al、Ta原子扩散迁移至{100}晶面，形成异类原子结合键及稳定的堆垛方式，是促使γ\'相形成N-型筏状结构的主要原因；而γ\'相不同界面的应变能密度变化是元素扩散及γ\'相定向粗化的驱动力。

5Ns. The peak position of N band emission as well as the distinct emission region slightly moves towards the open end of the cylindrical cavity, and this does not happen to O band emission. Radiation transport efficiency of 6% is obtained for the φ400×1200um cylindrical cavity heated by x-ray source with radiation temperature of 118 eV.

从时间分辨的X光强度轴向空间分布来看，在较长时间（约1～1.5ns）内，O带X光在整个观测缝对应的轴向范围之内均有较大的辐射强度，在X光强度空间分布的变化过程中，其强度峰值的空间位置基本不变；而对N带X光，则只在较短时间（约0.5ns）内，在整个观测缝对应的轴向范围之内可观测到X光辐射，但只在靠近输运源约300μm的范围内有较强发射，在柱腔末端600～700μm范围之内的辐射则很弱，N带X光辐射轴向空间分布曲线的峰值位置在朝柱腔末端的方向移动，移动量大约为130～250μm。
