不分离的

Bis (P—bromobenzylamino) ethane and 1,2—bis (m—Iodobenzylamino) ethane may be prepared by condensation of the corresponding halo benzaldehyde with ethylenediamine and followed by catalytic hydrogenation of the Schiff's bases over Pto_2 in glacial acetic acid solutions: Both Ⅱa and Ⅱb may react in neutral mediam with aldehydes to form well—defined crystalline tetrahydro—imidazole, which may be served as derivatives of identification for aldehydes: Under the same condition, however,Ⅱb may ...

用1，2-二乙烷与二十余种醛类作用，得到有固定熔点的晶体衍生物，它们的熔点分布在85—210℃之间，产率为40—96％，这试剂与甲基酮类在相同条件下无反应，因此，它可作为鉴定醛类的专属试剂。 2。上述衍生物用稀盐酸在室溫处理，能发生水解，可以定量地收回原来的醛，因此这试剂又可作为分离醛类的试剂。 3。上述衍生物可以用非水滴定法半微量地测定其分子量可作为鉴定醛类的另一项参考数据。 4.1，2-二乙烷与醛类能生成晶体衍生物，但这试剂也与甲基酮在同样条件下发生反应，所以不适合作为鉴定醛类的专属试剂。

Low resolution was obtained in genetic variation investigation of different cowpea cultivated germplasm of Vigna unguiculata based on ITS sequence data, while good results could be obtained in genetic diversity and phylogeny of differern species of genus Vigna.

RAPD可以用于种下的遗传多样性研究。但基于随机引物的RAPD-PCR扩增，受实验中各种因素的影响较大，导致数据获得的重复性不是很好、且不可移植。因此只能作为一种辅助方法。从技术上讲，为保证实验条件的一致性，应该一次PCR反应中对所有的研究对象进行扩增，并在扩增片段的电泳分离检测时尽量保持条件的一致。

Court orders and federal enforcement agencies are of inestimable value in achieving desegregation, but desegregation is only partial, though necessary, step forward the final goal of which we seek to release, genuine intergroup and interpersonal living……… A vigorous enforcement of civil rights laws will bring an end to segregated public facilities which are barriers to a truly desegregated society, but it can not bring an end to fears, prejudice, pride, and irrationality which are barriers to a truly integrated society………..

法庭判决和执法单位，固然在打破种族分离主义中，扮演不可欠缺的角色；但这样的种族分离主义是不全面，虽然这不完美但也必要。我们要往终极目标迈进，寻求解放，真正的跨越群体，人与人真诚的相处。。。一个强势执行的公民权利法律，能终结在公共设施的分离，那是真正没有分离主义社会的阻墙；但这并不能杜绝害怕，偏见，傲慢和非理性，那是真正的熔合社会的阻墙。。。

It was confirmed that facultative apomixes is existed in coffee species based on emasculating treatment, cyto-genetic observe and SSR marker detection.

细胞遗传学观察发现咖啡四倍体类型材料(2n=4x=44)的多胚和多胚苗中含有天然的单倍体胚和单倍体小苗(2n=2X=22)；去雄处理后，可见子房膨大，其中5份材料获得了果实和种子，初步说明无融合生殖现象的存在；对小粒种品种间杂交F1代个体的SSR分析，发现多胚苗中存在与母本图谱相同且不携带父本特异带的后代以及携带双亲特异带的有性后代，表明子代有仅来自母本的无融合生殖个体分离出来。 3 建立了咖啡无融合生殖的分子鉴别方法。

The triumph of scientific discovery, with which, as a rule, the representatives of Scholasticism in the seats of academic authority had, unfortunately, too little sympathy, led to new ways of philosophizing, and when, finally, Descartes in practice, if not in theory, effected a complete separation of philosophy from theology, the modern era had begun and the age known as that of Scholasticism had come to an end.

胜利的科学发现，其中，作为一项规则，代表院在座位的学术管理局已不幸的是，太少的同情，导致了新的途径philosophizing ，而当最后，笛卡尔，在实践中，如果不是在理论，影响一个完整的分离，从神学，哲学，现代的时代已经开始和年龄称为指出，士林已告一段落。

Eddard and his two daughters journey south to the royal court; Lady Catelyn stays at Winterfell with their three sons; and Eddard's bastard son Jon Snow, unwelcome company to the Lady Stark, leaves Winterfell to take the oath of service in protection of the Wall.

他危机的状况造成了Stark家族成员的分离，Eddard和他的两位女儿去了北方的皇家宫廷，Catelyn夫人和她的三个儿子一起留在了Winterfell，而Eddard 的私生子、Stark夫人不受欢迎的同伴，Jon Snow，因宣誓保卫Wall而离开了Winterfell。

"One way of doing minimally invasive surgery uses cutting trocars — and with that comes scarring, trocar site pain, and hernia formation," explained Dr. McCarus, noting that newer technology has emerged in the form of bladeless trocars with no cutting tips. The bladeless trocar penetrates by separating tissue fibers, thereby producing a smaller fascial defect and allowing repositioning of the tissue at port site after removal of the implement.

McCarus医师指出，切割式的套针是侵犯性最低的手术法之一，但是其所带来的负面效应也不少，包含疤痕、套针插入部位疼痛及疝气等；现在，新的技术所使用的套针不但没有刀刃，也没有锐利的切割尖端；这种无刀刃的套针，以分离纤维组织的方式作穿刺，因此对筋膜的伤害最低，且在手术完成后，所穿刺的组织部位可以自行再定位，不需缝合。

However, more and more studiespresent that the local pressure fluctuations in the separated and reattached region of bluff body are found tobe non-Gaussian. The Gaussian assumption will underestimate the wind load of cladding and cause thecladding to unsafety. It is a general way to estimate peak pressure by a fixed peak factor.

然而，有越来越多的研究表明，钝体绕流的分离和流动再附着区域的风压呈现出强烈的非高斯分布的特性，按照高斯分布进行峰值风压的估计将可能低估作用于围护结构上的风荷载而造成结构的不安全性。

If you will try to form a notion of yourself, of the sort of a something that you suspect to inhabit and partially to control your flesh and blood body, you will encounter a walking bundle of superfluities: and when you mentally have put aside the extraneous things—your garments and your members and your body, and your acquired habits and your appetites and your inherited traits and your prejudices, and all other appurtenances which considered separately you recognize to be no integral part of you,—there seems to remain in those pearl-colored brain-cells, wherein is your ultimate lair, very little save a faculty for receiving sensations, of which you know the larger portion to be illusory.

假如你试图构造出一个&你自己&的概念，构造出你觉得是在占据并部分控制你血肉之躯的这么一个东西的概念，那你就会遇上&一副行走着的皮囊&要你处理：你在脑海里会想着把这些与&你自己&无关的东西——衣裳、四肢、躯体、后天习惯、口味、先天特征、个人成见、以及分离之后你认为不是构成&你&所必需的其他部件——通通剔除出去，剩下珍珠般灰白色的脑细胞，就是&你&的老窝，但是残存其中的，除了知觉功能，好像就所剩无几了。而你知道，知觉又多半是虚幻之象。

Based on this, aim at the disadvantage on Wigner Distribution and Fractional Fourier Transform that can't restrain noise interference effectively when be used to detect Linear Frequency Modulated signals interfered by heavy noises, we proposed a improved WD. Simulation results show that this method can restrain noise interference effectively and improve the ability of LFM signals detection. On the other hand, in multi-component cases, WD suffers from the cross-terms, which may impair some of the auto-terms. In order to separate original multi-component signals into components and reconstruct them separately, we can use the method of optimal filtering in fractional Fourier domain. But this method also has a problem that if signals have aliasing in the fractional Fourier optimal domain as well, the reconstructed signals will be distorted. In this thesis, a novel method of quasi Fourier transform is proposed in order to solve the problem of multi-component signal reconstruction, and have good results.

在此基础上，针对Wigner分布和分数维傅里叶变换在处理高噪声背景下线性调频信号检测的问题时存在不能有效抑制噪声干扰的缺点，提出了改进Wigner分布的办法，该方法能够抑制噪声，提高信号的检测能力；针对Wigner分布在处理多分量非线性调频信号时存在干扰项的缺点，以及分数域最优滤波方法在处理多分量非线性调频信号分离重构问题时存在的局限性，该局限性表现为在对最优分数域上也有信号分量重叠的情况进行处理时重构信号发生畸变，提出了新颖的类傅里叶变换的方法，该方法对在最优分数域上也有信号分量重叠的情况也能处理，得到的重构信号失真很小。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.
