Now we have known that SARS-CoV encoded 11 varietal proteins. They have 4 constitutive proteins: spike protein, membrane protein, envelope protein and nucleocapsid protein. Spike protein trimer form spike and exsertion? virus peplos on the surface. Spike protein is archi-surface antigen component of virus, it has acceptor binding and membrane fusion activity. Spike protein has important effect at tissue tropism, cell-fusion and toxicity. Nucleocapsid protein can bind genome RNA to shape neucleocapsid. Membrane protein and envelope protein are necessary constituent to shape virus peplos. Spike protein is I-type membrane glycoprotein, it mediate virus binding with host cell epimembranal acceptor and to fuse host cell membrane.

SARS-CoV属于巢状病毒目、冠状病毒科，为单正链RNA病毒，基因组全长约29.7kb，已知编码11种蛋白，其中包括4种结构蛋白，分别是刺突蛋白、包膜蛋白、小包膜蛋白和核蛋白或核壳体蛋白。S蛋白三聚体形成突起，伸出包膜表面。S蛋白是病毒的主要表面抗原成分，具有受体结合和膜融合活性，在组织嗜性、细胞融合和毒力等方面起重要作用。N蛋白与基因组RNA结合形成核衣壳。M蛋白和E蛋白是包膜形成所必需的成分。

The project proposed and established the strict unique mathematical model of instantaneous frequency aiming at the currently existed problems in Hilbert Huang Transform form the viewpoint of physical connotative meaning; proposed and established the strict mathematical model of general intrinsic mode signal based on the concept of general continuous intrinsic mode signal and the compositive principle of practical general intrinsic mode signal; researched and proposed the fitting method of envelope lines in HHT from the viewpoint of theory, conquered the blindness and random in quondam EMD envelope line fitting and boundary treatment; developed a virtual time-frequency analyzer based on general intrinsic mode signal decomposition to open out the local time-frequency characteristics of nonlinear and nonstationary signal more deeply and accurately.

本项目针对希尔伯特-黄变换现阶段存在问题，从物理内涵的角度提出并建立了瞬时频率严格的唯一的数学模型；基于连续性的一般固有模态信号的概念和实际信号的一般固有模态信号的组成原理，提出并建立了一般固有模态信号严格的数学模型；从理论角度研究并提出HHT中的包络线构造方法，克服了原EMD的包络线构造和边界处理的盲目性和随意性；研发一台基于一般固有模态信号分解的虚拟式时频分析仪，使之可以更深入、准确地揭示非线性非平稳信号的时频局部特征。

The suggested method was applied to varying excitation pulse shapes: square envelope and chirped hyperbolic secant envelope.

本文将替换过程分为服务替换和路径替换2种方式，并详细介绍了这2种替换方式的实现方法。

Results With the new procedure, the tip of the prostate was peeled off completely without extra treatment, and this piece of the urethra,which was composed of surgical envelope, formed a vase-shaped natural surface to avoid urine irretention. The resected plane was covered by fibre and epithelium of surgical envelope,which could reduce irritation of urethra and bladder, and shorten hematuria and repair time. After enucleation of the enlarged prostate, the borderline became clear and blood supply was reduced, which facilitated the rapid resection without injury.

结果 采用新的切割方法前列腺尖部被完整剜除，无需修整，尖部尿道成为由外科包膜构成的喇叭口状自然界面，经过剜除的增生腺体，界面清楚，血供减少，利于快速切除，不易出现包膜损伤，切除效率明显提高。1000例手术顺利，术后发生短期尿道刺激症者150例，发生膀胱颈挛缩6例，尿道狭窄10例。
