This thesis mainly employs the density-matrix renormalization group to investigate the valence bond model. We deal with the one-dimensional and quasi-one dimensional benzenoid systems from medium to infinite sizes successfully and get the ground state energies, the first excited state energies and other properties for the first time.

Kinds of Schiff base derivatives of 2-N-benzylidene Furanmethanamine have been designed. The Net Charges of main atoms, bond lengths, bond angles, dihedral angles, IR have been calculated by means of HyperChem6. 0 program. 36 kinds of Schiff base derivatives of benzylidene adenine have been designed. Also the net charges of main atoms, bond lengths, bond angles, dihedral angles, IR, the energy gap △E between HOMO and LUMO and the nonlinear second-order polarizability β have been calculated by means of HyperChem6. 0 program. The calculated results indicated that the nonlinear second-order polarizability β were up in accordance with the △E down.

设计了腺嘌呤缩苯甲醛36种衍生物，计算了这些分子的气相几何，腺嘌呤缩苯甲醛中各原子的电荷分布，最高占有轨道HOMO和最低未占有轨道LUMO的能量以及它们之间的能量差△E，同时还计算了这些分子的二阶非线性极化率β，我们发现腺嘌呤缩苯甲醛的二阶非线性光学系数与△E有近似一致的变化关系，随着△E的减小，二阶非线性光学系数有增大的趋势。

Prana is the vital or bioplasmic energy which is universal in nature ,and consciousness is knowledghe .prana is known as the active and conscousness the dormamt aspect of our existence .consciousness , the spirit principle ,is called PURUSHA, literally meaning 'that which sleeps in the city'.

Prana是本质上普遍的至关重要或者原生态的能量，意识是智慧。能量可以保持生命存在，意识是我们休眠的另一种存在。从精神的原则上来说，呼叫PURUSHA，文学上讲是'城市的睡眠'。

Udana is the least dense of the pranas ,then comes prana ,samana ,and apana .vyana ,which flows over the whole body ,has a density which is the average of all the others .the different colors of the pranic or bioplasmic clouds are due to the emission of photons when electrons change their energy levels from higher to lower frequencies .

针对存在的缺点，本文提出了一种应用于激光多普勒测速的高精度信号处理技术，即首先利用加Hanning窗的Welch修正周期图算法得到信号功率谱，搜索其谱峰值频率，接着利用Goertzel频谱细化算法对搜索的谱峰进行细化分析，再引入能量重心频谱校正算法对细化后的谱峰进行校正分析，从而将离散频谱分析算法、频谱细化算法和频谱校正算法三者有机结合起来，充分发挥各自的优点：通过加Hanning窗的Welch修正周期图算法快速得到功率谱及峰值频率，通过Goertzel算法获得分析频带的高分辨率频谱，然后通过能量重心校正算法对细化后的频谱进行高精度校正，这样不仅保证了算法的高效性，而且大大提高了分析的精度。

Part of a personal energetic evolution that starts with rimay (the power to see reality without the screen of personal illusions and to express yourself authentically), moves to kanay (which involves the recovery of the memory of your authentic self as cocreator and the ability to be the memory "who you really are"), and culminates with atiy ( the power to actually push the Kawsay with conscious intent to manifest your desires and affect physical reality).

个人能量进化由 Rimay(不被自己错觉所蒙蔽，能看见真实并表达自己的能力)到 Kanay(找回同是共同创造者的真实自我记忆，以及&谁是真正的你&的能力)，最后达到最高境界 Atiy (能真正有意识推动能量的力量，意图将渴求显化并影响物质实相)。
