They do not always have an all-or-none effect; degrees of poison ing may occur, and at a given dose some substances are far more toxic than others (e.g., a pinch of potassium cyanide can kill, whereas a single dose of ordinary table salt must be massive to kill).

毒物不一定具有全或无效应；一些毒物的毒性比另一些毒物要大得多，如0.25克氰化钾就足以致命，而一次服用大量的精制食盐也会致命。

Greek courtier to Dionysius the Elder, tyrant of Syracuse, who according to legend was forced to sit at a banquet table under a sword suspended by a single hair to demonstrate the precariousness of a king's fortunes.

希腊传说中的叙拉古国王狄奥尼西奥斯的朝臣，据传说其被迫坐在上悬宝剑的餐桌旁，宝剑由一根头发系住，以此来暗示君王命运的多危

To Dionysius the Elder, tyrant of Syracuse, who according to legend was forced to sit at a banquet table under a sword suspended by a single hair to demonstrate the precariousness of a king's fortunes.

Samples in transitions of filters are optimized, which solves the problem that values obtained by look-up table method are not optimums. Aiming at prematureness appearing easily when GQA is used to optimize continuous functions with many peaks, IGQA is proposed.

针对遗传量子算法在优化连续多峰函数时易出现早熟的问题，提出一种改进遗传量子算法，典型函数测试表明，IGQA的性能优于GQA和其它几种遗传算法，收敛速度快，全局寻优能力强，能有效地克服早熟现象。

An instantaneous optimal semi-active control method is put forward. Combined sliding mode control with lyapunov's stability theory, the control weights matrix, which can minimize structural instantaneous energy, is designed. Simulation and shaking table test is conducted to validated the method's effectiveness. To solve combination explosion of controlled structural state encountered in high-rise building control, the semi-active control strategy, which can drive structural state point to reach the sliding mode switching band, is designed by using sliding mode control theory, and genetic algorithm is used to find the optimal semi-active switching to drive the structural state point to sliding mode switching band at prestissimo speed.

提出了一种瞬时最优半主动结构控制方法，利用滑模变结构控制理论和Lyapunov稳定性理论设计使结构瞬时能量最小的半主动控制权矩阵，仿真实例和振动台试验验证了本文所提方法的有效性和实用性；为解决在高层建筑半主动控制中半主动控制器状态组合爆炸的问题，利用滑模变结构控制理论设计在Lapunov稳定意义下使结构在运动状态空间中任一相点于以最快速率到达滑模切换带的半主动控制策略，并用遗传算法找出了最快到达滑模切换带的半主动控制切换组合。

食物上桌，崔佛坐下来崔佛：这些酸味裸麦黑贝果实在太完美了。

This two-part, 40-minute program from Yoga Zone uses a variety of poses (some of them joined together in flowing sequences known as vinyasas ) that are obviously directed at the abs; the scale pose, for instance, will certainly work those muscles hard, as will the table pose, the "forearm plank"(the upward pushup position, but with elbows on the floor), and others.

这两个部分， 40分钟的节目，从瑜珈区，使用各种构成（其中一些人一起在流动序列称为vinyasas ）表示，显然是针对ABS的；规模构成，举例来说，一定会的工作，这些肌肉的努力，将表构成，"前臂木板"（向上pushup地位，但与肘在地板上），以及其他。
