查询词典 rate

Biotite percusion figures are the consequence of high deformation rate, so its occurance would indicate the exsistance of naturally high deformation rate.

黑云母击象是快速变形的产物，因此它的出现可以指示自然快速变形的存在。

The death rate is one of the factors of population improvement besides the improvement of birth rate and incomers.

除了出生率的上升和移民人数的增加，死亡率的下降也是人口增长的一个因素。

The most they can exchange is 100,000 won (about $740 at the old official exchange rate; between $30 and $50 at the black-market rate).

他们最多能兑换10万元（以旧的官方汇率计算约740美元；以黑市汇率计算，在30~50美元之间）。

There were 8 embryos single blastomere amplified, and the amplification success rate was 72. 7%(8/11); 3 embryos' not amplified; 2 embryos'showed preferential amplification , and the PA rate was 25%(2/8); and the 7 tubes of blank with washing cell solution were not contaminated. We transferred 3 unaffected embryos to the uterus. But unfortunately, blood hCG was negative after 2 weeks of transferring indicating no pregnancy.

共8枚胚胎的单卵裂球得到扩增，扩增成功率为72.7%（8/11），3枚未得到扩增，2枚发生了偏性扩增(preferentialamplification，PA)，PA的发生率为25%（2/8），细胞洗脱液空白对照7管均无污染发生。3枚诊断为正常的胚胎被移植入宫内，不幸的是，移植后2周，血hCG阴性，证明未妊娠。

And there were statistical differences at 0.05 level of the parthenogenetic cleavage rate and blastocyst rate between development of parthenogenetic embryos in 3, 2 and 4 h.

结论］在39℃，3h内进行孤雌胚胎的运输，能获得较高的卵裂率、囊胚率。

The mitotic error rate in cleavage stage embryos was proven to be higher than the meiotic aneuploidy rate and as a consequence, the genome of a single blastomere is not representative for the genome of the other cells of the embryo.

在卵裂期胚胎这种有丝分裂的错误率被证明是高于减数分裂的非整倍体错误率，因此，单个卵裂球的基因不能代表其他胚胎细胞的基因组。

The method of Agrobacterium-mediated transformation is the most widely used in genetic transformation. To this day, only several genotypes such as Bobwhite and Yangmai158 have been used in transformation successfully. To widen the recipient genotypes, ten different genotypes were transformated by Agrobacterium-mediated In our study, transformation efficiency of B31706 and B31575 were significantly higher than Bobwhite. Moreover, regeneration rate and resistant plantlet rate of Agrobacterium-mediated genetic transformation in B31706 immature embryos callus was the highest one among the genotypes.

农杆菌介导法是目前应用较为广泛的转化方法之一，但在小麦中，只有包括Bobwhite和扬麦158在内的少数几个基因型被成功用于农杆菌介导的小麦遗传转化中，为了拓宽小麦农杆菌转化的受体基因型范围，本研究对10个不同基因型的材料进行了转化实验。B31706和B31575的转化率明显高于对照材料Bobwhite 。

RBNZ's Bollard kept the rate at a record low on March 11 and said monetary stimulus would likely be removed around the middle of 2010 amid higher bank funding costs and a "relatively sluggish" economic recovery with traders betting the RBNZ will increase its interest rate by 180 basis points over the next 12 months.

新西兰央行行长波兰德在3月11日宣布继续维持创记录的低利率水平不变，他还表示，新西兰将于2010年中期退出货币刺激措施，"相对疲软"的经济复苏使得投资者预期新西兰央行在未来12个月里将上调利率180个基点。澳元兑美元昨日创下了7周以来的最大跌幅。

To explain the time-resolved fluorescence depletion, we develop a dynamics theory of spectroscopy for a vibrational relaxation process, and a decay rate constant of the vibrational state on the excited electronic state is taken to be 〓〓 in which γ is vibrational relaxation rate constant of the transition 0→1 and k〓 is the Boltzmann constant.

电子激发态上的波函数可写作〓相比于以前密度矩阵理论的布居表象，本文所提出的波函数表象理论为在更本质的层次上揭示振动弛豫过程的物理图象，特别是研究超短脉冲激发下含有振动弛豫的动力学光谱创造了条件。

We employ the semi-classical Boltzmann\'s equation to govern the transport process of carriers and do the calculations on the emission rate and the capture rate.

对于发射率和俘获率的计算，主要考虑在粒子数守恒下，采用半经典的玻尔兹曼输运方程描述粒子输运的过程。

Hanna: That's over now, isn't it?

都结束了，对吗

You must be ill. You look so pale.
