This paper introduces the studies of the ultra-short Thomson scattering X-ray source at the accelerator laboratory of Tsinghua University in recent years. Properties such as the photon yield,the pulse length and time jitter of the produced photon pulse were predicted theoretically from the parameters of the electron bunch and the laser pulse,and the scattering angle. Preliminary experiments were successfully carried out with a 16 MeV backward-traveling-wave accelerator and the ns-Q switched laser provided by China Academy of Engineering Physics. This paper also introduces the 1.6-cell electron gun that was fabricated on site and the experiment with high RF power including the measurement of the electron bunche parameters. Based on these,we have designed an X-ray source,which is now under construction.

Rutherford and Teller were both immigrants who became fiercely patriotic in defense of their adopted countries. Both often behaved like overgrown children, losing their tempers over trivialities and then regaining their equilibrium with a friendly smile. Both were father figures to their students, taking care of students' personal problems as well as their professional education. Both were more interested in the strategy of science than in the tactics. Rutherford made the decision to explore nuclei with an accelerator, and then left the details of the accelerator to Cockcroft and Walton. Teller made the decision to build a hydrogen bomb or a safe reactor and then left the details to others. Both had a lifelong dedication to science, but spent more time helping younger people than doing research themselves. Teller published his version of the hydrogen bomb story under the title The Work of Many People. The names of Cockcroft and Walton appear on the letter to Nature announcing their discovery but Rutherford's does not. My name appears on the patent for the safe reactor but Teller's does not.

卢瑟福和泰勒都是移民，都对维护他们移民去的国家表示出狂热的爱国主义情绪；两者的行为都很像身体过度发育的孩子，对琐事大发雷霆，随后又若无其事，友好亲切；两者都对学生像父亲一样，既关心他们的个人问题，也关心他们的学业；两者都多科学研究的策略而不是技巧更感兴趣，卢瑟福决定用加速器研究原子，把有关加速器的细节问题留给卡斯喀特和华尔顿，泰勒决定造氢弹和安全反应堆，然后把细节问题留给其他人；两人都把一生献给科学研究，但花费在帮助年轻人的时间比自己做研究的时间要多得多；泰勒以《齐心协力》为标题讲述了他眼中的氢弹故事；卡斯喀特和华尔顿的名字出现在写给《自然》杂志宣布他们发现的信中，但信中没有卢瑟福的名字，我的名字出现在安全反应堆专利中，但也没有泰勒的名字。

The nerve root adumbration disintered completely after O3 injection,submerging sign disappeared about 28%,most nerve root disintered,submerging sign partly disappeared about 50%,no nerve root disinter about 22%.

First neurotrophic factors could be concentrated within nerve conduits. Second fibre-bridge to anastomose two parts of nerve gaps could be formed ecxactly. Third operation of nerve conduits could be transplanted easily.

神经导管一方面能使神经营养因子在导管内积聚，浓度增高，另一方面引导神经缺损两端准确对合，同时导管的植入操作简单，可以减少手术对神经的损伤。

Results: The numbers of Bombesin positive pulmonary cells, the lamina propria S-l00 protein, neuron-specific enolase positive nerve fibers, IgE positive cells, mast cells and IgE positive mast cells significantly increased in bronchiectasis. The changes of pulmonary endocrine cells, nerve fibers and IgE positive cells were more significantly in hyperplastic BALT areas. The S-100 and NSE were found in lymphoid tissue and BALT. A close contact was found between mast cells and the S-100 positive nerve fibers. An IgE positive outer zone was found on MC surface. Mast cells and IgE positive cells were seen in the bronchial epithelium and alveolar septa.

The nerve need not be present throughout the entire period of regeneration; once the limb has begun to grow and tissues are sufficiently differentiated, the nerve may be removed without impariment of the morphegenetic potency acquired by these tissues during their earliest stage of formation. Singer (1974) has shown that it does not matter for regeneration what type of nerve, whether motor, sensory, or autonomic, is present in the blastema.

但是再生的肋骨市是「不完全发育」，神经不会在整个再生过程中呈现出来；一旦，肋骨开始生长，而且组织得到足够的养分，神经就可以从器官器官再生的部位移除，力量，是细胞在早期形成的时间得到的Singer，则证明了：任何细胞组织，对再生来说，是不相关的，不管是运动、感觉、自动的，都在胚芽中呈现。
