查询词典 fold

Hydroxysteroid dehydrogenase/carbonyl reductase ( 3α-HSD/CR,EC 1.1.1.50 ) from Comamonas testosteroni is an inducible enzyme which catalyzes the oxidation of androsterone with NAD+ to form androstanedione and NADH. 3α-HSD/CR was a member of the SDRs family, whose crystal structure had been solved by X-ray diffraction in 2000. The structure of 3α-HSD/CR is a homodimer which shows a typical pattern of Rossmann-fold structure consisting of βαβ units, and reaveals similarity with other members upon the SDRs family.

中文摘要 3α-Hydroxysteroid dehydrogenase/carbonyl reductase ( 3α-HSD/CR，EC 1.1.1.50 )是从Comamonas testosteroni菌体中分离而来的诱发性酵素，利用NAD+为辅因子，将受质androsterone氧化成androstanedione并伴随NADH的生成而完成催化反应。3α-HSD/CR是属於SDRs家族成员之一，其立体结构已经在2000年利用X-ray晶体绕射所解出。3α-HSD/CR在结构上为一同源双聚体，并和其它家族成员一样具有βαβ二级结构所叠合组成的Rossmann-fold特徵。

The joint effect of active and reactive power on the voltage stability of a typical power system was considered by analysing the two parameter bifurcation problem related to nonlinear oscillation phenomena. Numerically, as the active power P1 increases, the Hopf points get closer and eventually coincide at P1=1.455 43 the cyclic fold curve gets closer and closer to the Hopf curve and finally intersects the Hopf curve at a singular point the period-doubling points also get closer and finally coincide at P1≈0.65. The stability behaviour is pre-determined using the normal form approach near the limit point of the Hopf curve. Hence, in the power system attention should be paid to both the consumption of active power and the decrease in the reactive power to prevent nonlinear oscillations. A controller can be designed to absorb some active power and to avoid the nonlinear oscillations that damage the system components.

针对一个典型的单机无穷大电力系统，通过分析系统的双参数分岔的非线性振荡现象，综合考虑有功和无功功率对电压稳定性的影响数值分析表明，随着有功功率的增加，电力系统的Hopf点越来越靠近，最终合为一点在P1=1.455 43处同时圈折cyclic fold 曲线也越来越靠近Hopf曲线，并在Hopf曲线的稳定与不稳定临界点处与Hopf曲线相交倍周期分岔点也随着越来越靠近，最终在P1≈0.65 合为一点应用正规形理论方法，初步确定了Hopf曲线极限点附近的稳定性态因而，电力系统应注意让负荷利用有功功率，减少无功功率的产生以防止非线性振荡另外，可以设计一个稍微吸收网络的有功功率的控制器，以避免因周期振荡而造成电力系统仪器的损坏或电压崩溃

The Star Fold was first explored by fringe-space mining operations, happy to drill, pack, and sleep back.

To evaluate which combinations of preprocessing and differential expression method perform well, we consider 4 popular preprocessing methods (MAS 5.0, RMA ,dChip and PDNN) and 5 popular differential expression methods (fold-change, two sample t-test, SAM, EBarrays and limma).

为了评估各种预处理方法与表现量差异方法组合的表现，我们考虑了四种常用的预处理方法：MAS 5.0、RMA、dChip及PDNN，与五种常用的表现量差异方法：fold-change、two sample t-test、SAM、EBarrays及limma。

To give consideration to both validity and reliability, six combinations are recommended when differentially expressed genes are less, RMA+fold-change, RMA+ SAM, RMA+ limma, PDNN+ fold-change, PDNN+SAM, and PDNN+limma. Three combinations are recommended when differentially expressed genes are more, dChip+ fold-change, dChip+SAM, and dChip+limma.

若同时注重信度与效度，我们推荐几种方法组合：当表现量差异基因个数少时，推荐RMA+fold-change、RMA+SAM、RMA+limma、PDNN+ fold-change、PDNN+SAM与PDNN+limma此六种组合；而当表现量差异基因个数多时，则推荐dChip+fold-change、dChip+SAM与dChip+limma此三种组合。

To more easily conceptualize and embody the learning in these stages of the cycle, they are set into a picture model of four cardinal, seasonal, and elemental directions, and an adaptation of Angeles Arrien's Forue-fold Path, and Ron Kurta' Sensitivity Cycle Barriers, as illustrated on the fold-out map at the beginning of each section of the book.

为了更容易地对这一循环中这些阶段的学习形成概念，并把这一学习过程具体化，我们插入了一个图片模型（这个模型是由四个主要的、周期性的基本方向组成的），及《Angeles Arrien's Forue-fold Path》的修订本和Ron Kurta的《灵敏度周期障碍》，如同这本书每一部分开始的插图一样。

JONATHAN MANN: From the word FOLD that's literally folded to LOOK looking out, Goldring has lost count of all the words she's respelled in her new script.

乔纳森·曼：从表示折叠意思的&FOLD&到&LOOK&的词，戈德林已经数不清楚她利用新写法拼出了多少个词。

For example, if I were to raise with K-J, and the flop came K-T-3, I'm either going to win a small pot, after betting my top pair and seeing my opponents fold, or I'm going to lose a much larger pot as my decent hand goes down in flames against two-pair, a set, or an out-kicked top-pair.

例如，我raise KJ，flop是K-T-3，我可能会bet，对手fold，赢一个小的pot，或者会输一个很大的pot，对手有2对，set，或者更好kicker的top pair。
