查询词典 umbral

In this thesis, we study some aspects in analytic combinatorics. The main contents can be summarized as follows. In Chapter 2, by classical umbral method, we obtain some properties and identities of invariant sequences. More generally, we study the self-inverse sequences related to sequences of polynomials of binomial type and the self-inverse sequences related to Sheffer sets, and give some interesting results of these sequences.

本文研究组合分析学中的若干问题，具体内容如下：第二章用经典哑运算方法研究了不变序列的性质及满足的恒等式，随后又推广到更一般的情形，即关于二项式型多项式序列的自反序列和关于Sheffer序列的自反序列。

Umbral banyans can speak Sylvan but rarely choose to do so.

每当幽影树怪勒死一个受害者，卷须便便会把尸体扔到外露的树根处，令其腐烂并成为自己生存所需的养料。

Half Damage from Piercing:Piercing weapons deal only half damage to an umbral banyan,with a minimum of 1 point of damage.

因为幽影树怪生于幽影位面，故它可以用同样的能力使自己从幽影位面传送到主位面的某个森林之中。

Figure 1 is an orthographic projection map of Earth (adapted from Espenak 1987) showing the path of penumbral and umbral shadows.

图一是地球图示的垂直视角，显示了半影和全影区（于1987年修订）。

The path of the Moon's umbral shadow begins in Brazil and extends across the Atlantic, northern Africa, and central Asia where it ends at sunset in western Mongolia.

月亮象征感知的能力，当一些人还在为这种能力和无理性的感觉感到恐慌时，另一些人已经理解了这种神秘力量并表示欢迎。

A special feature of the maps are the curves of constant umbral eclipse duration,i.e., totality, which are plotted within the path at 1 min increments.

地图有个特殊的特征是阴影区的曲线持续时间，其按每分钟为单位进行分割。

The adoption of one single value for k eliminates the discontinuity in the case of hybrid eclipses and ends confusion arising from the use of two different values; however, the use of even the "best" mean value for the Moon's radius introduces a problem in predicting the true character and duration of umbral eclipses, particularly total eclipses.

采纳单一的K值排除了使用2个不同的值在全环食时计算的衔接不上；然而，在使用这个最合适的值计算月球半径时出现一个问题，即预报的实际值和本影持续时间之间出现问题，特备在日全食的时候。

Anyone with Wilderness Lore or Knowledgecan use those skills instead of Spot to notice the umbral banyan.

位面传送：幽影树怪可以用一个即时动作将自己和被抓住的目标一起传送到幽影位面的一个森林中达5轮时间，效果与同名法术一样。

In contrast, the inner or umbral shadow is a region where the Earth blocks all direct sunlight from reaching the Moon.

每年月食最多发生3次，有时一次也不发生。

Consequently, the smaller k value produces shorter umbral durations and narrower paths for total eclipses when compared with calculations using the IAU value for k.

当于使用IAU 的K值比较，较小的K值得出较短的本影持续时间和较窄的全食路径，使用较小的K值导致更长的本影持续时间和更宽的全食路径。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
