查询词典 difficulty

A larger error often occurs in measured results by multi-specimen J-R curve method because of the difficulty in determining the blunting line equation. On the basis of considering the effect of loading rate on plastic-flow stress, a new blunting line equation in dynamic loading has been obtained: J=2NK0.5(subscript εFΔa.

针对多试样J-R阻力曲线法因钝化线的不易确定性常造成测试结果J误差较大的情况，考虑了加载速率对塑性流变应力的影响，给出了一新的动载条件下的钝化线方程：J=2NK0.5

And you may have difficulty determining a good one.

你可能很难确定一个好的。

In Gregory scheme, not only the importance of the moist static energy is taken into account, but also the common difficulty of the moist convective adjustment scheme, the determination of the temperature profile, is obviated. At the same time, it can give the vertical profile of the apparent heat source Q〓 and apparent moisture sink Q〓. Gregory scheme has the clear physical image that includes the cumulus updrafts, cumulus downdrafts,cumulus induced subsidence in the environmental air, entrainment,detrainment and evaporation. In addition, the interaction between the cumulus and the environment is described by one-dimensional bulk model. It is simpler than the Arakawa-Schubert scheme and has no difficult to decide the spectrum of clouds accurately.It is propitious to operational use because of its simple calculation. Finally, Gregory scheme is not only suitable for moist convection of all types, but also for dry convection.

在该方案中，既强调了湿静力能能量的重要性，又回避了给定临界温度廓线的困难，并且还能给出真实的视热源Q1，视水汽汇Q2的垂直廓线；同时Gregory方案又具有很清晰的物理图象—积云中的上升运动，下沉运动，环境中的补偿下沉运动，以及卷入，卷出和蒸发等；此外，Gregory方案用总体云群模式来描述云与环境的相互作用，比型积云参数化方案简单，它避开了型方案中云谱需要精确设置的麻烦问题，计算容易，简便；最后，Gregory方案在湿对流中适用于浅，深，中不同的对流深度，并且也适用于干对流过程。

If the communication system is very complex but there is no adaptive feature and the whole behavior pattern emerges in the course of a single-stage rigid development, any small biological deviation from the mean is likely to alter the receptive and productive capacities for patterns, thus rendering individuals that are not perfectly replicated incommunicado, and this difficulty in communication might bar them from interacting with the group.

如果沟通系统相当复杂，但却没有适应性特徵，而且整个行为形态在一阶段的精确发展的过程中浮现，那麼，在生物学上任何一点偏离平均值都可能会改变这此形态的接收及产出能力，於是使得非完美复制的个体完全的孤立，如此沟通上的困难会阻止他们和团体互动。

The infinite deviousness of "the ruling classes" and the immense difficulty of the left's task are a given in these halls. In 2004, Solnit published a much-praised book, Hope in the Dark: the Untold History of People Power, challenging the instinctive pessimism of many leftists.

对会议厅里的这些人来说，"统治阶级"的极度狡诈和左派面临的巨大困难都是上天注定的。2004年，索尔尼特出版了一本倍受赞誉的书《黑暗中的希望：未揭示的人民力量的历史》，该书质疑了许多左派人士的天生悲观主义。

Diagonalization of square matrix is a difficulty learning problem in linear algebra and it also is an important character for square matrix.

对方阵可对角化的充要条件的理解，一直是线性代数学习中的一个困难问题。

The intraperitonealLD_(50) values in mice of VES and VDPG were 0.16mg/kg and 0.39mg/kg,respectively. The intraperitoneal LD_(50) value in cockroach of VDPG andVES were 2.32μg/g and 1.87μg/g, respectively. After intraperitonealinjection of the venom in mice, the main poisoning symptoms includedlethargy, ataxia, diaphoresis, convulsion, anorexia, shortness of breath,and difficulty to open eyes, etc. Whereas the mice injected withphysiological saline acted normally.

两种粗毒都对小鼠和蜚蠊有较强的毒性，其中毒囊粗毒和电刺激粗毒对小鼠的LD_(50)值分别为0.39mg／kg和0.16mg／kg；毒囊粗毒和电刺激粗毒对蜚蠊的LD_(50)值分别为2.32μg／g和1.87μg／g体重；小鼠经腹腔注射粗毒后，出现无生气、共济失调、排汗、痉挛、食欲减退、呼吸短促、睁眼困难等症状，而注射生理盐水的小鼠活动正常。

While this was never confirmed, there is no difficulty for the PLA Navy to do so since the missile has already been successfully integrated with the Type 039 diesel-electric submarine.

虽然这从未被证实，这么做对PLA海军是没有困难的因为导弹已经成功地与039型柴电潜艇一起整合。

Under bivariate normal models, we characterize the classification problems of differential difficulty via parameter tuning.

在二维常态模型下，我们透过参数选择来刻划不同困难度的分类问题。

So I want to learn English. But I know that is difficulty to me.

所以我想学习英语，但是我知道这对于我来说是困难的。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
