I was loath to spend our last Shot too hastily; so I call'd my Servant, not my Man Friday, for he was better employ'd; for with the greatest Dexterity imaginable, he had charg'd my Fusee, and his own, while we were engag'd; but as I said, I call'd my other Man, and giving him a Horn of Powder, I bad him lay a Train, all along the Piece of Timber, and let it be a large Train; he did so, and had but just Time to get away, when the Wolves came up to it, and some were got up upon it; when I snapping an uncharg'd Pistol, close to the Powder, set it on fire; those that were upon the Timber were scorcht with it, and six or seven of them fell, or rather jump'd in among us, with the Force and Fright of the Fire; we dispatch'd these in an Instant, and the rest were so frighted with the Light, which the Night, for it was now very near Dark, made more terrible, that they drew back a little.

我不愿匆匆放完最后一排枪,就叫来了自己的仆人。我没有叫星期五,而是叫了我新雇的那个水手。星期五有更重要的任务要完成。在我们开火的时候,他以惊人的速度给我和他自己的枪装弹药。所以我说,我叫的是新雇的仆人。我给了他一角火药,命令他沿着那长木头把火药撒下去,撒成一条宽宽长长的火药线。他照着办了。他刚转身回来,狼群就冲了过来,有几只甚至已冲上了那长木。我立即抓起一支没有放过的手枪,贴近火药线开了一枪,使火药燃烧起来。冲上木料的几只狼给烧伤了;其中有六、七只由于火光的威力和惊恐,竟连跌带跳地落入我们中间。我们立即把它们解决了。其他的狼被火光吓得半死,加上这时天已黑下来,火光看起来就更可怕了,这才使那些狼后退了几步。

The established system should be ideal for studying soybean and cucumber nematode and garden balsam breeding of flower dwarf architecture.

The results showed that when the concentration of Pb(superscript 2+) was lower than 400 mg/L, effect on the germination root length, bud length, root weight, bud weight, the root activity and the proline content of the garden balsam were not obvious.

结果表明,当Pb(上标 2+)浓度低于400mg/L时,对凤仙花种子的发芽率、发芽势、幼苗的长、芽长、重、芽重、系活力及脯氨酸含量影响不大,当Pb(上标 2+)浓度为800mg/L时,对凤仙花种子才开始表现出明显的抑制作用。

The plantlets of soybean, cucumber and garden balsam were inoculated by wild-type Agrobacterium rhizogenes K599, and hairy root was induced on inoculated sites in vivo. The frequencies of hairy root induction from wound cotyledons of soybean, cucumber and garden balsam were 100%, 65% and 91%, respectively.

In this paper,we have presented an autonomous guidance strategy based on optimal states feedback technology.First,by utilizing classical Gauss motion equations,we derived the three separate control laws,which could maximize the time rate of change of a desired orbital element.

首先利用传统Gauss型运动方程,推导出三个轨道数增大最快的独立控制律;然后据当前数与目标值的偏差量对独立控制律进行加权组合;最后为高效可靠地获得最优制导律,采用一种遗传算法和逐次二次规划相结合的混合方法对权重进行了优化。

First, by utilizing classical Gauss motion equations, we derived the three separate control laws, which could maximize the time rate of change of a desired orbital element. Then, the separate control laws were blended based on the deficit between current and target value of orbital state. Finally, to obtain the optimal guidance law effectively and reliably, a hybrid method combining genetic algorithm with sequential quadratic programming was used to optimize the weight values.
