随机信号

We successfully identified JSRV mRNA expression and proviruses DNA in sheep lung tissues infected with JSRV and control group has no postive signals,Validating the use of exogenous virus-specific DNA probes in the analysis of oncogenic proviral integration sites and identification of integrated exogenous proviral sequences.

用地高辛随机引物法标记exJSRV特异的env片段，制备探针，原位杂交检测SPA肺组织中的RNA及前病毒DNA，结果表明SPA患羊肺组织内有JSRVenv基因mRNA的表达，同时也检测到了前病毒DNA，而相应的阴性对照却无阳性信号，证实外源性病毒特异的DNA探针在致瘤性前病毒的整合位点和整合的外源性前病毒的检测中具有可信度。

As the analysis and measurement of yarn evenness occupies special importance to the quality controlling of many textile products, three main problems on the topic, which are: the mathematical modelling of the ideal slivers and yarns, the digital algorithms for measuring variance-length curves, spectrograms and imperfections, and the system design of the yarn evenness tester of a digital type, are studied in the dissertation mainly from the viewpoint of the subject of signal processing with the applications of the theory of stochastic processes and the technique of wavelet analyses.

纱线条干均匀度的分析和测量对纺织品质量的控制和提高具有重要的意义。本论文从信号处理的角度出发，应用随机过程理论和小波分析方法，着重研究了条干均匀度分析和测量中的二个主要问题，即理想纱条的数学建模问题和变异曲线、波谱图及疵点的数字测量问题，并进行了数字型条干均匀度测试仪的设计和研制工作。

Methods: Twenty-four male SD rats were randomly divided into normal control (NC, n=6), protein C activator (PCA, n=6), lipopolysaccharide (LPS, n=6) and LPS+PCA group (n=6). NC group were given normal saline and PCA group were injected protein C activator (0.4 mg/kg) through vein of the tail. LPS group were administered lipopolysaccharide (10 mg/kg, 4h) by intraperitoneal injection method to make the model of septic shock rats. After the animal model was made, LPS+PCA group were injected protein C activator (0.4 mg/kg) through vein of the tail. 30 minutes after the injection, each rat was tested by Medlab biosignal analyzing system for observing mean arterial pressure and left ventricle function, the activity of LDH and iNOS in myocardium and the cuttings of myocardial tissues.

取SD雄性大鼠24只随机分成对照组、PCA组、LPS组和LPS+PCA组四组，对照组尾静脉注射生理盐水，PCA组尾静脉注射蝮蛇毒蛋白C激活物，LPS组腹腔注射LPS (10 mg/kg， 4h)的方法建立败血症休克的实验动物模型，在建立败血症的实验动物模型的基础上，尾静脉注射PCA (0.4 mg/kg)为LPS+PCA组，每只大鼠均于药后30 min时运用Medlab生物信号采集处理系统记录平均动脉压和左心室功能指标，并测定心肌中乳酸脱氢酶活性、诱导性一氧化氮合酶活性及心肌病理切片。

It's difficult to process the signal in t raditional way. Pret reated by a quasi- syn-optical path compensating method , which eliminates the interferences resultign f rom fluctuating voltage and tempera2 ture.

为此，利用了准共路光路补偿方法对信号进行预处理，分析表明在一定程度上可以消除光源起伏和外界光路随机微弯损耗以及温度变化所带来的干扰。

But whereas previously SETI was forced to rely on the random meanderings of the telescope across the sky, it will now be able to look for signs of alien intelligence in a systematic survey of the entire sky.

然而以前的 SETI 只能依赖于望远镜在空中随机的漫步，如今可以系统地调查整个星空寻找外星智能的信号。

But as you can see,just so a radom comparance and signal give us the direction,how can we take profit by that?

但你可以看到，只要一随机comparance和信号给我们的方向，我们怎样才能考虑利润吗？

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
