查询词典 envelope environment

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。

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。

The brother really think only to so much, and feel very lost, because the removal of his grandfather, the elders gave away 100 yuan, can be uncle and grandfather only to 10 yuan, he was lost and angry, ran out, and I see uncle grandfather He went out on and my parents talked for a while, then my brother came in and told me 10 yuan should Jiuyeyeshuo and grandfather from the maternal uncle took over the red envelope, my brother open the red envelope a look at 100 yuan, just wiped out those who feel frustrated, he is like a rose to heaven from hell, like happy people who jumped up.

弟弟真的以为只给那么多，感觉到非常失落，因为除去他爷爷以外的长辈都给100元，可舅爷爷就只给10元，他很失落和生气，跑出去了，我舅爷爷看他出去了，就和我爸爸妈妈聊了一会，后来我弟弟进来了，就对我舅爷爷说10元钱也要，并从舅爷爷手中接过了红包，弟弟打开红包一看是100元，刚才那些感到失落的心情一扫而光，他就像一个从地狱升到天堂的人一样高兴的跳了起来。
