Master pointed out that god makes this body very durable to last for eternity, yet we damage it through overwork, or by poisoning it with various intoxicants or unnecessary activities, and even wearing out our minds by all kinds of nonsensical schemes, plans and negative thinking
師父提到上帝設計這個身體本來是很耐用的，可以長生不老，只可惜我們過度工作，或是用毒品殘害自己，或是浪費精神作無謂活動，甚至還用否定的思考無謂的計畫等等來消耗心力。 -
The current interest in melatonin is wintnessed by the growing number of scientific papers directly or indirectly dealing with this molecule, in the last 10 years, the mean number of articles has doubled and reports on new compounds acting at the melatonin receptors abound, although the search for a clear therapeaatic role for these ligands is still under way beside the scientific interest, there is a contemporary, but largely independent, explosion of a free market of various products containing mt, which have been presented at antiage agents protecting against differe kinds of injuries, although this action still lacks a solid scientific foundation. indeed while a number of physiological action of mt are coming to light, the exact role and the the real therapeutic benefit of this compound still remain unclear, both have been the subject of debate. with a lot of potential actions still to be fully demonstrated and with some mechanisms deserving more clarification, in sense, the appellation of the hormone of darkness, attributed to mt beacause of its characteristic concentration / time profile, seems extremely appropriate
除科學興趣以外，也有暫時的，在很大程度上不可靠的有關各種含有mt的產品開發的探索，如出現的保護多種損傷的抗衰老劑。盡管這些產品的作用仍缺少堅實的科學基礎，事實上當mt的許多生理作用研究清楚后，這種物質的確切作用和真實的治療效果仍不得而知。有許多潛在的作用需要充分論證，有些機理需要進一步區分，在某種意義上說，稱mt為黑暗激素，主要是由於在某一時間的特定濃度分佈似乎更合適。 -

We put the emphases on the soft output viterbi algorithm ( sova ), which is one of turbo code ’ s decoding algorithms, and presents the derivation and computation step of the sova decoding algorithm. after presenting sova and map decoding algorithms and analyzing four kinds of decoding algorithms, the paper makes a comparison among the different decoding algorithms by emulation analysis, and analyzes the time complexity of various algorithms, and then contrasts them. in the last part of this paper, according to the criterion recommended by the consultative committee for space data systems ( ccsds ), including code rate,
根據空間數據系統顧問委員會（ ccsds ）為turbo碼應用於深空通信系統推薦的標準，包括碼率、碼塊大小、分量碼類型、約束長度、碼生成多項式，以及交織器的選擇等參數的建議以及sova譯碼演算法的理論基礎，設計了sova演算法的實現結構，通過模擬驗證了本文所採用的turbo碼的性能，從而證明turbo碼確實是一種很好的通道糾錯編碼方式，它適用於要求功耗低或信噪比低的深空通信系統中。 -
The developments of high - speed circuits and mmic pose the problem of analyzing the circuits characterized both in time and frequency domains. a variety of mixed time - frequency methods have been developed during the last quarter century in the research of the vlsi interconnect and package analysis and nonlinear steady - state analysis. this paper examines these methods from a unified point of view. various mixed problems are formulated as circuit equations in the mixed time - frequency domain. fundamental approaches to slove the equations are given, from which all of the published mixed methods can be naturally deduced. this facilitates the comprehension of these methods and is helpful for their applications. some new ideas are proposed based on the cross reference among these different kinds of methods
隨著高速集成電路及mmic （微波單片集成電路）的發展，提出了對時-頻混合表示電路進行分析的任務.本文用統一的觀點考察了通常屬于高速電路互連與封裝分析、非線性電路穩態響應分析兩個不同方面的混合分析問題，指出這類問題的實質是要求解一個時-頻混合的電路方程，給出了求解這一方程的基本思路，闡明了現有的各種方法是如何從這一基本思路導出的.這可為認識這些方法的本質與聯系，促進它們的應用與發展提供參考.此文還探討了某些方法之間的相互借鑒，提出了若干新的想法 -
In this paper, i studied the theory of wavelet in the field of sensor faults diagnose. then i discuss the effects that using various kinds of mother wavelet detect sensors faults in the concrete simulated example. at last, we studied the application of combining the wavelet and bp neural networks to sensors failure detection and simulated sensor faults diagnose by the computer
本文主要研究了小波分析在傳感器故障診斷中的應用，詳細地探討了各種小波基函數在傳感器故障診斷中的應用，並通過具體的模擬實例對各種小波基函數在傳感器故障檢測中的效果進行驗證，最後研究了結合小波分析和bp神經網路進行傳感器故障診斷的技術，同時做了計算機模擬診斷。 -
But, pso convergence ' s speed become slow in latter iterative phase, and pso is easy to fall into local optimization. at present, some scholars improve base pso mostly using 3 methods : disperse algorithm, increase convergence speed, enhance particle ' kinds. in the paper, i put forward 2 methods aiming at local best resutl but not whole best result. i modify base pso using the last method. some scholars put forward times initializations, so i select best result after circulating some times to be a parameter of formula. first, put particle into some small region, and ensure every region having one paticle at least. second, every region ' s particle has probability transfer other regions. although increase running time, enhance particle ' kinds, decrese the probability of convergence far from whole best result. nerms ( network educational resource management system ) is one of the research projects in the science and technology development planning of jilin province. the aim of nerms is to organize and manage various twelve kinds of network educational resources effectively so that people can share and gain them easily and efficiently, so as to quicken the development of network education
但粒子群演算法仍存在如下不足:首先在多峰的情況下，粒子群有可能錯過全局最優解，遠離最優解的空間，最終得到局部最優解;其次在演算法收斂的情況下，由於所有的粒子都向最優解的方向群游，所有的粒子趨向同一，失去了粒子間解的多樣性，使得後期的收斂速度明顯變慢，同時演算法收斂到一定精度時，演算法無法繼續優化，本文對原始粒子群演算法提出了二點改進方案: 1 .演算法迭代到一定代數后，把此時找到的全局最優解當作速度更新公式的另一參數（本文稱之為階段最優解）再進行迭代; 2 .每次迭代過程中除最優解以外的每個粒子都有一定概率「變異」到一個步長以外的區域，其中「變異」的粒子在每一維上都隨機生成一個步長。
