恒定

A radiosurgery treatment planning was performed on the selected nerve segment, its changes of pathology and ultrastructure were observed. Results: Base on the dissection, the rabbits' sciatic nerve was composed of the seventh lumbar nerve and first and second sacral nerves. The sciatic trunk descended in front of the sacroiliac joint and escaped between the sacral bone and ilium, then left the pelvis from the greater sciatic notch. The segment of sciatic trunk which ran between the sacrum and ilium was stable and feasible for localization according to the related bony structures in CT scanning, so it was selected as irradiation target.

结果：通过解剖可见坐骨神经主干由第7腰神经和第1、2荐神经组成，坐骨神经主干从荐髂关节下、荐骨和髂骨之间穿出后，跨过坐骨大切迹的一段坐骨神经主干位置恒定，且有荐骨和髂骨做定位标志，可作为CT定位的照射靶点，单次大剂量照射后镜下可见神经纤维变性坏死。

The recent developed WBE model that the metabolic theory of ecology was applied to self-thinning law arose highly debates. The major questions addressed were whether slope of self-thinning line is constant (-3/2 or-4/3) and how environment influences B-D relationship.

尤其是基于代谢生态学理论建立的WBE自疏规律提出后，密度调控规律的争论和研究更为活跃，其焦点主要是自疏线斜率是否存在相对恒定的α值和值的大小。

The control signals of the PWM rectifier are obtained by comparing the current of AC side with triangular wave (or saw-tooth wave) directly, which can implement the steadiness of the voltage of DC side and unit capacity factor of the system. At the same time, harmonic component of the system is abstracted through Instant Reactive Power Method, which can be smoothed by Integrated Learning Boost Converter Control.

本文采用重复学习Boost变换技术，利用滑模变结构控制技术对单相PWM整流器恒频Boost变换进行了分析，提出将交流侧电流直接与三角波相比较得到开关控制信号的方法，实现直流电压恒定不变及系统单位功率因数；同时，利用瞬时无功功率法分析系统谐波，并在谐波域内使用重复学习的控制方法，结合Boost变换技术，有效滤除系统谐波有功电流。

The results show that with the increase of deformation strains and thinning of Fe-Cr fibers, the saturation magnetization are about 140 A·m2/kg constantly, and the remanent magnetism and coercivity increase gradually.The magnetic properties of Fe-Cr fibers are invariant when the Fe-Cr fibers were preserved in absolute alcohol or air for more than 1 a. After Fe-Cr fibers heated in air at temperature higher than 300 ℃ for 1 h, the Fe-Cr fibers transform from ferromagnetic α-solution to paramagnetic2O3, and the saturation magnetization of samples decreases remarkably. With the increase of deformation strains, the thermal stability of thinner Fe-Cr fibers decreases.

结果表明：随着变形量的增大和Fe-Cr纤维的细化，纤维的饱和磁矩基本恒定(约140 A·m2/kg)，而剩磁和矫顽力则逐渐增加； Fe-Cr纤维在无水乙醇和空气中储存一年以上，磁性基本保持不变； Fe-Cr纤维在空气中经300 ℃以上加热1 h后，逐渐由铁磁性的α-固溶体转变为顺磁性的2O3，饱和磁化强度显著下降；且随着变形量的增大，较细Fe-Cr纤维的热稳定性较差。
