查询词典 be derived from...

Roman family name which was possibly derived from Latin hora "hour, time, season", though the name may actually be of Etruscan origin.

如果你的外教真的给你的名字拼写是"Stok"的话，应该是恶搞咯。

Furthermore, the NBO calculation implies that relative stabilities of all 15 conformers can be attributed to the steric and hyperconjugation effects. In addition, the result derived from G3MP2 shows that the heats of formation of all conformers are positive and heats of formation of ring conformers are greater than those of chain conformers.

而且，NBO的立体和超共轭分析表明立体交换排斥能和超共轭作用对这些分子的相对稳定性起了重要作用。G3MP2计算结果表明氮氢化合物的生成热均为正，并且环状分子的能量和生成热都高于链状分子。

The solitary wave can be generated considering Goring and Raichlen's movement of a paddle. The proposed original linear solution for the solitary wave generation is expressed in the hypergeometric function. Two disadvantages of the original solution with large trailing wave and skewed wave profile are found by comparing with the theory of solitary wave derived from Boussinesq's equation.

本文并以弱非线性的孤立波造波问题做为解析之对象，由於孤立波造波板速度为一超越函数，造成解析上的困难；本文以 hypergeometric 函数推求常微分方程式之全解，并与理论波形解比较后，发现由於未考虑非线性及分散性过强等问题，使得线性暂态解较理论波形拉长与歪斜，可能无法有效描述孤立波造波问题，故针对线性之分散关系做出修正。

In the first form, instance must be an instance of Class or of a class derived from it.

第一种形式中， instance 必须是 Class 或其派生类的一个实例。

Based on a chosen normalized boundary equation, a new normalized boundary equation can be established such that the irregularity of the kernel of integral equations is overcame. Finally, natural frequency is obtained by the existence condition of nontrivial solution of the discrete algebraic equations derived from the integral equations.

边界方程有多种选择，在选定一种边界方程的基础上，可以通过建立一个新的边界方程来表示问题的边界，以克服积分核的奇异性；最后由积分方程的离散化方程组有非平凡解的条件，求得固有频率。

In this method, stability safety coefficient is derived from th e ratio fo internal energy to external energy and the minimum disturbed energy e quivalence surface is established, which can be used to determine the potential sliding surface.

该方法不仅从能量的观点给出了基于增稳内能与失稳外能比值的稳定安全系数，还将干扰能量法与等值面法结合起来，建立了用最小干扰能量等值面来确定潜在滑动面的方法。

Finings can be isinglass, gelatin, egg albumen, modified casein, chitin (derived from the shells of crabs or lobsters) or ox blood.

Finings可以鱼胶，明胶，鸡蛋蛋白，改性酪蛋白，甲壳素或牛血。

Data from Keck Observatory was used to derive the speed of the clusters along the line of sight, allowing the three-dimensional geometry and dynamics of MACS J0717 to be derived.

基于凯克天文台的数据用来测定星系团沿我们视线方向的速度，由此我们获得了MACS J0717的三维运动关系。

We have seen that this law of inertia cannot be derived directly from experiment, but only by speculative thinking consistent with observation.

我们已经知道，这个惯性定律不能直接从实验得出，它只能根据思索和观察得出。

Phylogenetic tree derived from all known EPVs spheroidin gene indicates that the order of the EPV host is in relationship with the genus of corresponding EPV, which agrees with a recent point that "Lepidopteran EPVs and Orthopteran EPVs should be divided into two distinct genus".

对已知的几种昆虫痘病毒球状体蛋白基因做系统进化树，结果显示，以病毒寄主的昆虫分类目作为昆虫痘病毒的分属依据，更符合分子水平的分析结果，也与近年来许多学者所提出的"将鳞翅目与直翅目昆虫痘病毒分为2个不同的属"的观点相一致。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
