Prefilter Design Method for Weak Signal Detection with LIA .

基于锁相放大的微弱信号检测电路前置滤波器设计。

The chromatin unfolding assay showed that ,like the wild-type transactivation domain, two variants that represent benign polymorphisms did not induce chromatin unfolding or only induced subtle change. Contrary to the behaviors of the wild type and two benign variants, four cancer-predisposing mutations in the transactivation domain superactivate the chromatin unfolding. The results suggest that the chromatin unfolding assay can aid in the characterization of deleterious mutations in the C-terminal transactivation domain of BRCA1 and may provide more reliable presymptomatic risk assessment.

对这些重组质粒的染色质伸展活性检测表明，野生型pwt和两种良性多态性突变体不具有染色质伸展活性或只有极微弱的染色质伸展活性，而其他4种乳腺癌易感突变体均具有过强的染色质伸展活性，提示利用染色质伸展技术可预测BRCA1转录激活区基因型与乳腺癌发生风险的表现型的关系。

Result: The genetic similarity coefficient was varied from 85.4% to 98.4%. The variation of protocorm, germination and monoleaf were rather more notable than that of bileaf and inflorescence.

结果：发现不同阶段内遗传相似系数较大，在85.409 3%～98.360 6%，其中在原球茎、萌芽期和一叶期存在的变异比两叶期、开花期要显著，但程度都极其微弱。

Can we reignite the spark even as it grows cold and weak?

生命之火能重新燃起，即使它已变得寒冷微弱？

Once, we entered a mountain valley, arrives at the middle time, the star axle struggles suddenly is being called us to retrocede loudly, when the Queen of night last withdrawal mountain valley time, the summit heavy snow sudden avalanche, the entire mountain valley is buried, in the heavy snow avalanche's sound loudly, the star axle rapid breath appears that weak, must be cut off likely, she is really similar to the crystal butterfly is the same, cannot withstand including any wind and snow.

有一次，我们走进了一个山谷，走到中间的时候，星轨突然挣扎着起来大声叫着我们后退，当月神最后一个退出山谷的时候，山顶的大雪突然崩塌，整个山谷被埋葬，在大雪崩塌的轰然之声中，星轨急促的呼吸显得那么微弱，像要断掉，她真的如同水晶蝴蝶一样，连任何风雪都承受不住。

Combined crystallization kinetics analysis obtained via rheometry and morphological observation of crystals growth performed on POM, two different mechanisms of shear-enhanced crystallization for PP/ grafted MWCNTs composites were suggested:(1) at low temperature, strong heterogeneous nucleation plays a dominant role on the. crystallization behavior, which would be saturated at a higher filler content, and the effect of shear-enhanced crystallization was weak;(2) at high temperature, the effect of heterogeneous nucleation was substantially depressed, and the crystallization of the composite was obviously accelerated by pre-shear and the thread-like crystallites were generated earlier than the spherulites.

结合流变测试结果和热台偏光显微镜观察的结晶形貌发展过程，对于PP／G—MWCNTs体系得到了两个不同的剪切影响机理：(1)在低温条件下，强烈的异相成核作用对结晶行为的影响占主导优势，而剪切作用对结晶的影响十分微弱，同时，在填料含量较高是，异相成核作用具有饱和性；(2)在高温条件下，异相成核作用被抑制，复合体系的结晶主要受到预剪切作用的影响，并且纤维状晶体较球晶更易生成。

The Hegyi single-tree competition index also showed there was in-tense competition between Bruguiera gymnorrhiza and Rhizophora slylosa to survive. And it could be prognosticated that Bruguiera gymnorrhiza and Rhizophora slylosa will live together for a long time, while Bruguiera gymnorrhiza will have a little superiority during this competition.

结果表明，木榄和红海榄有极其相似的生态位宽度和极高的生态位重叠关系，Hegyi竞争指数模型计算的竞争强度也证明，木榄和红海榄之间存在有激烈的生存竞争，并预测到木榄和红海榄将长期共存，但木榄在竞争中有微弱的优势。

Brockville Recorder and Times, Canada- Jul 31, 2006… RIDEAU FERRY — By the slim margin of one pound, pro angler Charles Sim won the Canadian Fishing Tour's Big Rideau Open on Sunday.

布罗克维尔录音机和倍，加拿大-2006年7月31日扛rideau轮的微弱一磅，亲钓鱼查理辛荣获加拿大捕鱼旅游大rideau开放周七。…比如

Compared with flunarizine and nimodipine, in addition the Chinese herb tetramethylpyrazine has the beneficial effects on the antagonism of brain Post-ischemic hypertension or increase of PAP and PCWP, while tetrand- rine showed weak amelioration effects on brain resusci- tation, which may be due to its no selectivity on brain or brain vesseles.

与氟苯桂嗪和尼莫地平相比，中药川芎嗪还具有对抗脑缺血后继发性外周血压和肺血管压升高的独特效应。而汉防己甲素的抗脑缺血损害效应微弱，可能与此药对脑血管、脑细胞选择性作用较低有关。

Diurnal Es may provide a weak, scattery signal virtually every day over an Es-distance path.

昼夜ES 也许提供微弱， scattery 信号实际上每天在ES 距离道路。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
