The opening-up vision angle of this paper is to embark on the track of mentality and life of LiZhi at first, then pose the treacherous character of LiZhi"s, which is the intrinsic gene ,the traditions of be in business ,all sorts of belief in the group of LiZhi"s and was born in the OuanZhou -which is border on the sea, the above cause make LiZhi have the habit of not being bind up by the orthodox of the Confucianism. In his anchorless experience, we play emphasise on the four city桻uanZhou, Beijing, NangJing and HuangAn of the HuBei province, which have an important effect upon LiZhi"s life, then thread the place (homeplace and the place where he act as an offical) the character JiaoHong and the brothers of the Gen ,the incident(the dispute between of GenDingXiang and LiZhi together, by which we can lay out the full life of LiZhi and the process of his heresy idealistic ,we can draw a conclusion that LiZhi"s suicide is a deep consideration, that the pertinacious will of the pursuit for the truth and the fearless of the fighting spirit are the history achievements of LiZhis life .

全文论述的展开视角是先从李贽的心理轨迹和人生轨迹着手，揭示出李贽叛逆性格的内在因子、经商家世的传统和家族信仰多样化的优势以及地处泉州这个开放地域的大环境影响使他过早地就栽下了不为正统儒学束缚的根基：在他的一生漂泊经历中，又重点截取泉州、北京、南京及湖北黄安四个对李贽一生有重大影响的地理位置，通过综合地点、人物、事件的铺叙，立体面地展示李贽的活动内容及其&异端&思想成型扩张轨迹；李贽的最后自刎是其经过理智选择后所做出的最佳告别人世方式，其追求真理的顽强意志和大无畏的战斗精神即是他的人生价值之所在。

Then, the relation between vibration and sound, the acoustic holography method, the indeterminacy and identifiability of BSS, the BSS algorithm are discussed in detail. Based on above researches, the dissertation is divided in following four sections. The first section investigates the BSS algorithm suitable to acoustic feature separation. The algorithm of the joint approximate diagonalization of eigen-matrices is proposed. The spectra or the time-frequency distributions of source signals are the interesting features in ABD and they are separated from mixing signals by JADE algorithm. Then, the convolutive mixing model is transformed into a high-dimension instantaneous mixing model, and the deconvolution of source signals is achieved by the joint approximate block diagonalization of eigen-matrices. The proposed algorithm has a global minimum, and it is unsensitive to noise interference.

论文首先概述国内外声学诊断研究进展与盲分离研究进展，给出机器噪声声场与盲分离的数学描述，讨论了声振辐射、声全息、盲分离模型、盲分离可解性、盲分离结果不确定性、分离算法等基本问题，在此基础上，论文的研究工作分为以下四个部分：第一部分研究适用于声学特征分离的盲分离算法，提出基于特征提取的联合近似对角化盲分离算法，该算法以频谱特征或时频特征作为分离目标，从混合信号中分离源信号频谱特征或时频特征，最大限度地保留了与声学特征提取有关的频谱特征或时频特征，采用模型变换把卷积混合模型变换为一个高维瞬时混合模型，通过联合近似分块对角化算法实现源信号频谱特征与时频特征的盲反卷积。

This system mainly contains the front-end pulse interception and back-end software analysis. In the first part, we used a non-invasive infrared measurement method based on the dual channel simultaneous measurement technique. We measured the photo-plethysmograph from the subject's fingers and toes simultaneously, then used an analog circuit and central control unit to process the signals. Finally, the digital volume pulse data is processed by a personal computer. Because the characteristic points of digital volume pulse always occur in sharp variations, this paper proposes two algorithms to solve this problem. First, we find the pacemaker and percussion wave peak from transient slope variation, and then locate the dicrotic notch and dicrotic wave peak by using the wavelet transformation algorithm. When we analyze the data, we use the Visual Basic graphical user interface, which together with the Matlab is the core of the system.

Subsequently,enol methylation of P in basic condition completed the synthesis of malyngamide O.Applied this route to the synthesis of malyngamides Q and R,the chiral unsaturated acid was connected with the vinyl chloride part by amidation,then the resulting product was converted into the corresponding aldehyde,followed by aldol condensation of the aldehyde with the chlorotitanium enolate of pyrrolidone to complete the skeleton of malyngamides Q and R,then the synthesis of them was completed via enol methylation in acid condition.

The results of in situ DRIFTS on propylene oxidation show that the allyl species originated from α-H abstraction of propylene were located at the wavenumbers of 1454 cm~(-1) and 1427 cm~(-1). The rate-determining step is the abstraction of an α-H abstraction from a lattice oxygen linked to a bismuth ion to form a π-allyl intermediate coordinated to a molybdenum ion. The metal-oxo group then attacks the allyl intermediate forming a σ-bonded oxygen-allyl species, which is in a rapid equilibrium with the π- bonded species. The σ-bonded species then transforms to acrolein by further abstraction of α-H. Such species as formate, carboxylate, carbonate transform to deep oxidation products. The acetone was derived from propylene by an enolic species at lower temperatures.

Answer: The covenant of grace was administered under the Old Testament, by promises, prophecies, sacrifices, circumcision, the passover, and other types and ordinances, which did all foresignify Christ then to come, and were for that time sufficient to build up the elect in faith in the promised Messiah, by whom they then had full remission of sin, and eternal salvation.
