查询词典 ultrasonic

The envelope method of signal based on the Morlet wavelet as well as the relativity methods based on the curve of Gauss function and energy is used to analyze and calculate that the simulative exploration system of tiny terrain incepting the returning echo of ultrasonic,and the spacial position of echo headstream can be attained accurately.

利用Morlet小波信号包络和高斯函数曲线及能量相关性方法对拟设计的微地形探测系统接收到的超声波回波信号进行分析与计算，能准确获得回波源的空间位置。

The functions of signal emmitting, incepting, magnifying, data collecting and processing, displaying graphics, determinantdefects, as well data saving and outputting are realized. The saving problem of traditional ultrasonic testing is solved, and some infection factors of handlers are reduced. In virtue of technology of digital analysis and processing.

实现了检测过程的信号发射、接收、放大、噪声处理、数据采集、回波图形显示、缺陷判定、以及检测结果存储、回放和输出，解决了传统超声检测无记录等问题，减少了人为因素的影响。

Objective:In order to evaluate the healing coruse in physiology and pathology,the author analyses 96 cases of the ultrasonic images about uterine incising after cesarean section.

目的：为了解剖宫产术后子宫切口的生理与病理愈合过程，对96例B超观察剖宫产术后子宫及切口的声像图进行分析。

The sample was then rinsed with 10% HF + 40 % HNO3 + 50% H2O, ultrasonic-cleared in acetone, dried, oxygenized in H2O2, rinsed, dried, sterilized, and lixiviated. L-929 cells were cultured in vitro and assigned into negative control, surface oxidation (surface oxidation + NiTi-SMA leaching liquor), and non-treatment groups (NiTi-SMA leaching liquor alone).

用10%HF+40%HNO3+50%H2O进行酸洗，丙酮中超声波清洗，干燥，在H2O2溶液中氧化，再经清洗、干燥、灭菌、浸提等处理。L-929细胞体外培养，实验分为阴性对照组：培养液培养；表面氧化组：面氧化处理NiTi-SMA浸提液培养；未处理组：未经处理NiTi-SMA浸提液培养。

The structure of the organosilane moieties and ultrasonic treatment time were all significant for the quantities of grafted amino groups .

有机官能团的结构和超声波处理的时间对于嫁接有机基团的量很重要。

Two separate 8 channel multiplexed ultrasonic systems are incorporated, with the following features included

集成了两个独立的8通道多路超声系统，有如下特点

Methods Rats were infected with MP for 9 times during a period of 24 weeks by ultrasonic nebulizing inhalation to establish animal models of chronic pulmonary MP infection. In situ hybridization was performed with bFGF cDNA probe and results were quantitatively analysed to measure the changes of bFGF mRNA expression in lung tissues.

将8只大鼠于24周内反复9次经超声雾化吸入肺炎支原体以复制其慢性肺部感染模型，另以4只为对照，随后用bFGF cDNA核酸探针行核酸分子原位杂交及定量图像分析，观察肺组织bFGF mRNA表达的变化。

At present, diesel oil plays a more and more important role in the various kinds of fuel. But compare to gasoline, diesel oil has a high rate of sulfur compound. The sulfur compound is existed mainly as thiphene and thiphene ramification. These kinds of sulfur compounds are not easy to remove by adding hydrogenation. Thats why diesel oil has a high rate of sulfur compound. So it makes profound desulfurization a hot topic and a difficult problem in and outside the country. This paper takes dibenzonthiophene as a model to study the profound desulfurization of diesel oil with the help of biology and the oxygenating desulfurization under the condition of ultrasonic and microwave.

目前，柴油在燃料油中占的比重越来越大，而柴油较汽油馏分重，其硫化物主要以噻吩及噻吩衍生物的形式存在，这类硫化物用加氢的方法难以脱除，使柴油的含硫量较高，因此柴油的深度脱硫是国内外研究的热点和难点，本文以二苯并噻吩作为模型化合物，考察微生物的协同条件下对柴油的深度脱硫，超声波条件和微波条件下的氧化脱硫，并对超声波条件和微波条件下柴油的深度脱硫进行了对比。

But there are vocal mimics too, like a palatable species of tiger moth that deters bats by parodying the ultrasonic clicks of a toxic moth the bats detest, or like the greater racket-tailed drongo of Sri Lanka, which mimics the calls of other birds to drum up a mixed-species flock in which the drongos can more safely and efficiently forage.

但是也有针对声音的欺骗术，比如有一种自身美味无比的灯蛾会很搞笑地模仿一种令蝙蝠厌恶的毒性飞蛾的超声波频率，藉此逃避被吞吃的命运；还有一种长着像火箭似的尾巴的伊斯兰卡燕卷尾（反正是一种鸟，我以前没听到过，长相如何请参见wiki，点这里。
