查询词典 not until

By notknowing that, for example, SARS had in fact surfaced in November of one yearbut would not be revealed until the April of the following year, China put things in a closet, which prevents akind of inescapable improvement that you see in India.

譬如，因为人们不知道 SARS 实际上在那一年的11月就已经浮出水面了，但是，直到第二年的四月，才公之于众。中国把这个事儿瞒得严严实实。如果放在印度的话，这就会妨碍印度的势在必然的改进。

There are other things that we know now that he could not possibly have known—the importance of other greenhouse gases (methane in particular, which wasn't recognised as an important contributor to anthropogenic forcing until 1974, but also chlorofluorocarbons and N2O, which have also increased dramatically because of human influence) and the role of human-emitted particulates and low-level ozone precursors.

还有一些我们现在知道，但普拉斯不可能知道的事情：其它温室气体（特别是甲烷，直到1974年才被认为是人类对气候产生影响的重要因素。其它还有含氯氟烃和N2O，它们也因为人类活动而急剧增加）的重要性和人类排放的微粒及地面附近臭氧前体的作用。

The problem was not solved completely until the invention of the marine chronometer in the eighteenth century.

这个问题直到十八世纪发明了航海经线仪才得以解决。

For example Virgin Director Richard Branson was famous as a CEO, but he did not become a global celebrity until he attempted to circumnavigate the globe in a hot air balloon.

例如维尔京主任理查德布兰森是著名的首席执行官，但他没有成为一个全球性明星，直到他试图在环绕地球的热气球。

I'd rather not rile the citizenry until we have a better understanding of what we're dealing with here, Tirion said.

我可不想激怒平民，直到我们对我们正在处理的这件事有了一个更深的认识，提里奥说。

Tetraploid embryos could be produced by electrofusion at the stage of two-cell embryos, which could develop to blastocysts followed by fusion of cytoplasm and nucleus and cleavage in vitro. During the fusion of cytoplasm, the DNA methylation levels of the fused embryos are as high as these of two-cell diploid embryos in vivo Then the embryos are rapidly demethylated when the nucleus begin to fuse, resulting in the lowest DNA methylation levels when the nucleus are fused completely. After that, the DNA methylation levels of the fused embryos are gradually increased until the morula stage. However, whereas an asymmetric distribution of DNA methylation is established in vivo-derived blastocysts with a higher methylation level in the inner cell mass than that in the trophectoderm, we can not detect the asymmetric distribution in most in vitro-derived tetraploid blastocysts.

结果表明：利用电融合方法制备的小鼠四倍体胚胎在体外培养体系中经历细胞质融合、细胞核融合及细胞继续分裂发育直到囊胚期的过程，在细胞质融合的时候胚胎卵裂球同体内体外培养二倍体胚胎一样，呈现高度甲基化状态；在细胞核开始融合的时候，甲基化水平急速下降，在细胞核完全融合的时候甲基化水平达到最低点；随着胚胎继续分裂，胚胎甲基化水平逐渐增加，在桑葚胚期甲基化水平最高；但是囊胚期四倍体胚胎内细胞团同滋养层细胞甲基化荧光信号没有差别，这与体内体外培养二倍体囊胚内细胞团细胞甲基化荧光强度高于滋养层细胞甲基化荧光强度不同。

Tetraploid embryos could be produced by electrofusion at the stage of two-cell embryos, which could develop to blastocysts followed by fusion of cyto-plasm and nucleus and cleavage in vitro. During the fusion of cytoplasm, the DNA methylation levels of the fused embryos are as high as these of two-cell diploid embryos in vivo Then the embryos are rapidly demethylated when the nucleus begin to fuse, resulting in the lowest DNA methylation levels when the nucleus are fused completely. After that, the DNA methy-lation levels of the fused embryos are gradually increased until the morula stage. However, whereas an asymmetric distribu-tion of DNA methylation is established in vivo-derived blastocysts with a higher methylation level in the inner cell mass than that in the trophectoderm, we can not detect the asymmetric distribution in most in vitro-derived tetraploid blastocysts.

Tetraploid embryos could be produced by electrofusion at the stage of two-cell embryos, which could develop to blastcysts fellowed by fusion of cytoplasm and nucleus and cleavage in vitro.After fusion of cytoplasm, the DNA methylation levels of the fused embryos was very high as well as two-cell diploid embryos in vivo.Then the embryos was rapiddly demethylated when the nucleus begin to fuse, resulting the lowest DNA methylation levels when the nucleus fused completely.After that, the DNA methylation levels of fused embryos were gradually increased until the blastocysts stage.However, whereas an asymmetric distribution of DNA methylation was established in an vivo-derived blastocysts with a higher methylation level in the inner cell mass than in the trophectoderm, in most vitro-derived tetraploid blastocysts, we can not detect the asymmetric distribution.

Up to my marriage time, my mother had asked me to marry a man should according with followed requests: kind and honest、from clerisy family、age within five years、graduated student、refuse foreigner. For which, my mother had not expressed her opinion on my several dates until she saw my husband. She showed her admirations to my husband with all the qualities she expected, kind and generous, smart and handsome.

我的几次恋爱她都不置可否，但最后我把我先生带回家的时候，从母亲的眼睛中看出了极大的满意，我先生高大英俊的外表、年轻帅气的风度，令母亲大为赞赏，我先生达到了母亲的一切要求，我也从此离开了充满循规蹈矩的家。

This is because the bandwidth required for a lot of time, CPU can only wait until the next clock cycle will be needed, because memory could not keep pace with CPU frequency.

这是由于当对带宽的需求很大的时候，CPU只能够等待下一个时钟周期才能够得到所需要的数据，因为内存的速度跟不上CPU的频率。
