An on-line blind source separation algorithm of non-stationary mixed signals is presented. The algorithm uses the multiple time-delayed decorrelation and natural gradient rule to obtain the stationary point of the cost function, only a small number of observed samples is needed to minimize the Frobenius norm of the correlation matrices, so the computing cost is low and continuous separation calculation could be realized by on-line operation.

利用一种基于多时延解相关准则的代价函数和自然梯度原则，分别推导出非平稳信号在瞬态线性混合及卷积混合情况下的在线盲分离算法，仅通过对有限个时延样本的相关矩阵进行Frobenius范数最小化运算得到分离矩阵，计算工作量小，无需对样本进行分块处理，可实现对信号的连续跟踪操作。

Indeed, this is one significant advantage which Trinidadian lovers have over persons from less heterogeneous societies: once we do not shut ourselves off from the wider culture, we naturally learn that the important qualities of a human being lie beyond race, religion, ethnicity and class.

实际上，特立尼达的情人们有较多的来自非异性恋社会就是一个显著优势：一旦我们不拒绝了解更广阔的文化，我们就会很自然地了解人类在人种、宗教、种族和阶级之外的其它重要因素。

Corporationism studied the Cold War in the context of the 20th-century America and indicated that the Cold War was a natural result of the corporationist pursuit of American leaders such as Hoover and Roosevelt for an international order after the American example.Depolarizationism emphasized Britain's role in the origin of the Cold W...

社团主义学派将冷战置于20世纪的美国历史长河进行考察，认为冷战是20世纪初以胡佛和罗斯福为代表的领导人追求社团主义秩序的自然延续，其目的在于推进美国主张的政治经济秩序；非极化主义强调英国在冷战起源中的作用。

Maher hit upon the beneficial effects of fisetin when she screened a collection of flavonoids, substances with anti-oxidant activities found in many plants, for their neuroprotective abilities in tissue culture models of neurodegenerative disease.

通过实验观察到，非瑟酮对健康实验鼠的神经细胞的生长，增强记忆有保护和促进作用。Maher说：&这是中央神经系统分子水平的自然物质的作用首次被发现，而且表明能增强LTP和长期记忆。&

The daily lives of the people of such nonindustrial societies are likely to be patterned around their physical needs and natural events rather than around a time schedulebased on the clock.

在这样非工业社会的人们的日常生活中，他们以自己的生理需求和自然事物而非钟表上的时间来制定计划。

CM serves as a forum for the exchange of information on etiopathogenesis, epidemiology, diagnosis, therapy, and prevention of infectious and noninfectious diseases of laboratory animals; naturally occurring and induced models of human disease; research applications of animals; and the biology of laboratory animals.

比较医学》作为一个论坛，致力于关于发病机理，流行病学，诊断，治疗和预防实验室动物的传染和非传染疾病，自然发生和外因导致的人类疾病模式，动物研究应用和实验室动物的生物学等方面的信息交流。

At present it is widely accepted that the damages of the nasal turbinate bones and mucus caused by Bordetella bronchiseptica laid the foundation for the invasion toxigenic Pasteurella multocida. The mixture of Bordetella bronchiseptica and toxigenic Pasteurella multocida, together with some other factors, is the main cause of natural AR.

经过多年研究，现在大多数学者认为，支气管败血波氏杆菌能引起一定程度的鼻粘膜和鼻甲骨损害，但这些病变的严重后果是为正常猪鼻腔不能定居的产毒素多杀巴氏杆菌建立感染铺平道路，Bb和T+Pm的混合感染加上非传染因素交织在一起，是在自然条件下临床型AR的发生原因。

Results 42 of 45 patients had a history of subarachnoid hemorrhage for 1 to 3 times. 23 and 22 cases died separately before and after digital substract angiography. 5 cases of rebleeding was relating to angiography, 24 cases died during the "high risk" period (4 to 10 days after first rupture). Rebleeding accounted for a 7.2% mortality of aneurysms preoperatively in our study. Among them, 71% was attributable directly to rebleeding, whereas 29% to non-neurological complications.

结果 45例病人中42例既往有1～3次蛛网膜下腔出血病史，住院后于数字减影脑血管造影前出血死亡者23例，造影后出血死亡者22例，其中5例出血与脑血管造影有关，24例再出血发生在动脉瘤自然出血高峰期内(4～10天)，住院期间出血死亡的发生率占我院同期动脉瘤总数的7.2%，直接死于再出血的为71%，死于非神经系统并发症的为29%。

I once saw the soul and the body not the infant of cooperation, the symptom will not cry and will not smile, not touch he keeps original shape forever; The modern medical science explanation say is be born cerebral is squeeze but with the result that disease, probe it because of really not so suffer from this paroxysm infant parents or Ye milk necessarily is the sin deeply heavy To, there is heart doing some inquisition summaries, here say of the sin was deeply heavy to be not necessarily sentenced by the customs law, is a serious unscrupulous Towhee everybody arrived at the human life all according to the way of nature.

我見過靈魂與身體不協作的嬰兒，症狀是不會哭、不會笑，不觸動他就永遠保持原狀；現代醫學解釋說是出生時腦血管受擠壓而致病，深究其因並非如此，患此疾病的嬰兒父母或爺奶必是罪孽深重之徒，有心者可以做些調查總結，這裡說的罪孽深重不一定是被世俗法律定過罪，是嚴重的缺德之徒。每個人來到人間時都是依照自然之道。

As the first assembled chromosome from a member of the grass clade and the first non-Arabidopsis plant chromosome reported, it is a very important contribution to plant biology and as such is worthy of publication in Nature.

作为首次发表的来源于谷类作物组装的，非拟南芥植物的完整植物染色体，这篇文章对于植物生物学有着非常重要的贡献，是应当在《自然》杂志上发表的。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。
