箭

A dark resinous extract obtained from several tropical American woody plants, especially Chondrodendron tomentosum or certain species of Strychnos, used as an arrow poison by some Indian peoples of South America.

箭毒一种黑色的树脂提取物，可从几种热带美洲的森林植物中获取，尤指从南美洲的防己藤或乌贼属的某些种类中提取的，被南美洲的某些印第安族用作抹在箭矢上的毒药

In section 2.2,we prove that if the set of arrows in a quiver is not empty,then NQ is not semisimple.We construct the nonsovable subalgebra of NQ when there is no less than one circle whose length is bigger than one ,and there is no loop in quiver Q,thus leads to a conclusion that NQ is nonsovable .

我们还对只有一个单循环和一个单循环及若干单箭头的箭图，给出了其项链李代数的某些中心元素的具体形式，在2.2节中，我们对非平凡图，即当箭图中有箭头时，利用H中的元素证明了N_Q不是半单纯李代数。

The Jacobi matrix rank one update problems, given either their mix-type eigenpairs or their pricinpal submatrix and defective eigenpairs(the eigenvalues of the matrix and some elements of the corresponding eigenvectors) are also discussed.

n阶对称箭形矩阵与n阶Jacobi矩阵一样只有2n-1个非零元素，类似Jacobi矩阵逆特征值问题的提法，本文提出并讨论了六类对称箭形矩阵逆特征值问题，研究了这类矩阵的结构性质，得到了问题有解的充分必要条件及求解的数值算法和数值算例。

The sudra Ekalavya learnt archery in the forest before a clay image of Drona; He worshipped the image as the living Drona; that by itself enabled him to attain mastery in archery.

首陀罗伊卡拉维瓦在森林里的德罗纳粘土肖像面前学会了箭术；他把那个肖像当作活生生的德罗纳来敬拜；通过它而使他掌握了箭术。

The article is elaborated in advocate when arrow plume line is being set inside switchyard, section puts car line amount and effective length consideration, with the system foundation of actor melt into offers new method and conclusion proposal, make design of arrow plume line more reasonable and effective.

本文阐述在主调车场内设置箭翎线时，分段存车线数量及有效长度计算，以系统优化为基础提出新的方法和结论建议，使箭翎线设计更为合理有效。

I need a bow, arrows and a target to practice archery.

我要用一个弓、箭和箭靶去练习射箭。

It still is shenjijian, it is not v3 rocket or rus kaqusa rocket, ofcause today powder and rocket advenced a lot. and it is a top secret can not got confirmation and we need prove the Tungus mysterious explode by shinkijeon test

它仍然是神机箭，不是V3导弹或者喀秋沙火箭炮，当然今天火药和火箭技术比以前先进多了，并且它是顶级的机密不能证实，我们需要考证一下通古斯大爆炸是韩国人在测试神机箭

It fell to earth I knew not where;That can follow the flight of a song.Long, long afterwards in an oak,I found the arrow still unbroke;And the song, from beginning to end,I found again in the heart of a friend.

我以为我再也找不到我的箭和歌，但是希望多少年以后，我的箭还是牢牢地钉在树上，我的那支轻快的歌仍记在一个朋友的心间。。。

In order to explore the extraction method of proteome and technique of 2-DE, we compared the extraction method between the TCA-ac-tone and the Tris-HCl, and improved the key steps of 2-DE. The Tris-HCl extraction was the most appropriate for Antiaris toxicaria seed proteome analysis because of the highest resolution and more informative 2-DE map. Those were the solid basis for the later research of studying on the discrepancy expression proteomics of Antiaris toxicaria Seed.

在探索适合箭毒木种子蛋白质组学研究双向电泳方法中，比较了三氯乙酸－丙酮沉淀法、和Tris-HCl法，以及对双向电泳过程中的关键步骤的改良，认为Tris-HCl法为最适方法，所得图谱背景清晰，蛋白质信息量最大，为箭毒木属植物的差异蛋白质组学的后续研究打下了坚实的基础。

Arid, broiling environment, let life flinch, but, here still has a kind of arboreous and castiron ground to growing, because live without other tree in desert, these tree often are chopped to fall by native, draw out quiver of empty make it, so they are called quiver tree.

干旱、酷热的环境，让生命望而却步，但是，这里仍有一种树木不屈地生长着，因为沙漠里没有别的树木生存，这些树木就经常被土著人砍下，掏空做成箭袋，所以它们被称为箭袋树。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down
