Firstly, the equation for stress intensity factors under static uniform pressure is used as the reference case, and then the weight function for a thick-walled cylinder containing a radial edge crack can be worked out. Secondly, the dynamic stresses in uncracked thick-walled cylinders are solved under internal impulsive pressure by using mode shape function method. The solution consists of a quasi-static solution satisfying inhomogeneous boundary conditions and a dynamic solution satisfying homogeneous boundary conditions, and the history and distribution of dynamic stresses in thick-walled cylinders are derived in terms of Fourier–Bessel series. Finally, the dynamic stress intensity factor equations for thick-walled cylinder containing a radial edge crack subjected to internal impulsive pressure are given by dynamic weight function method.

首先采用静态内压下的应力强度因子作为参考解，得到了带径向边裂纹厚壁圆筒的权函数；然后用振型函数方法推导无裂纹厚壁圆筒在冲击内压下的动应力响应，分析中将相应的弹性动力学方程解分为满足非齐次边界条件的准静态解和满足齐次边界条件的动态解的叠加，利用傅立叶-贝塞尔级数展开，推导出了厚壁圆筒内动应力的响应历程和分布规律；最后由动应力权函数方法导出带径向边裂纹厚壁筒在冲击内压下的动态应力强度因子计算公式。

He looked for the root of literature and caused the upsurge of the literature of looking-for-root,but he protested that it was for nowadays firstly.His production accorded with any character of the culture of post modern unmeantly,but he considered that we ought to overrun the vogue a bit only.He pursued earthliness but refused ogling snobishness and kept aloof from literary event on his own.He combined the inheritress and animadversion toward conventional thought of ru,dao and fo and the reference of the culture of west.He formed a new inspirit of humanism by them.

他在文学中寻根，且引发了寻根文学的热潮，却主张寻根"首先是现在的"；他在创作中于无意间切合了后现代文化的某些特征，但认为只应"走在时尚前面一点"；他追求通俗，却拒绝媚俗，主动疏离"文学事件"；他把对传统儒道佛思想的继承、批判和对西方文化思想的借鉴、吸收有机结合起来，形成一种新的人文精神。

The instrument simultaneously sample for three phase voltage and current. Rotary photoelectric coding switch and LCD are used for human-computer interaction. it makes the interface compact and efficient. Utilizing the function of positive and negative edge trigger of the programmable counter array unit in MPU, signal zero-cross is captured for the phase detected based on double way. The software synchronism sampling method based on real-time parameter self-optimizing minishes period truncation error, and the measurement accuracy is improved. The digitization power measure imports traditional two-unit and three-unit methods and expands application range of the instrument. The capacity is discriminated by soft ware table-look-up on the load loss. The value of a quantity is converted to the value when reference temperature (75 ℃) from test temperature.

With the translation of Buddhist scriptures into Japan's gradual understanding of the "China" and began referring to the use of such air and sea in its master of poetry,"Ling-set","China is Taiwan's Yue Man sequence" of the sentence, of course, at that time "Shina language with a copy of the translators Buddhist usage, but is not common reason for this is has always been to China, said the Japanese usually morokoshi, tohn, and so on, these are the Japanese characters for" Don "the pronunciation Generally reflect the Chinese culture, especially culture of the Tang Dynasty of Japan's far-reaching impact on later Song, Yuan, Ming and Qing dynasties change, said Japan can not change China as "Don" habit did not change the Japanese Chinese culture of respect, admiration psychological. In 1713, Whitehead Arai from Edo shogunate orders, inquiries were drifting in Rome to talk too much about the history, a lot of opportunity to understand the world situation, a reference to China's "Kun Maps", Prepared for a title,"Song laid Introduction," in the world geography, history and more from his Department to listen to on the pronunciation of chi-na, to use katakana and that in the lower left-hand corner is attached to "Shina.

随着佛经的译入，日本逐渐了解"支那"所指并开始使用，如海空大师在其诗集《性灵集》中，有"支那台岳曼殊序"之句，当然，那时"支那一语带有模仿佛经译者的用法，但并不普遍，究其原因，主要是一直以来，日本人通常称中国为morokoshi、tohn等，这些都是日本人对汉字"唐"的读音，大体反映了中国文化，特别是唐朝文化对日本的深远影响，以致后来宋、元、明、清历代更迭，都无法更改日本人称中国为"唐"的习惯，也没改变日本人对中国文化崇敬、羡慕的心理。1713年，新井白石奉江户幕府之命，查询罗马的漂流者史多提，趁机了解了不少世界情势，参考了中国的《坤舆图说》，编写了一本题名为《宋览导言》的世界地理书，他把从史多提处听来的关于chi—na的读音，用片假名来表示并在左下角附以"支那字样。

The stealth warplane for the microwave radar usually have complicated structures with the coating of wave absorption. On the base of calculation and modeling of the geometrical structure of the warplane in real size, the HF RCS of the air crafts under two different polarizations in different direction have been calculated with the FDTD. The result shows that the above mentioned stealth warplane have the obvious characterstics of frequency resonance, polarization and the relatively large RCS in HF Band 10-30dBm2, which can be used as the theoretical reference for selection of working frequency for sky wave OTH Radar and it also means that the sky wave OTH radar has good capability of anti-stealth targets quantitatively.
