生存竞争

With network being introduced into traditional media, and the broadening of people on-line, the network has become Infobahn and medium autobahn in work and deed,and become the accelerator oflife anagenesis of the society.

随着传统媒介纷纷上网和网民队伍的日益扩大，网络不仅成了真正意义上的"信息高速公路"和"媒介高速公路"，成为人类社会生命进化的加速器，而且正在将人的生存竞争演变为一种全新的数字竞争、传播竞争和网络生存竞争，并催生了一种前所未有的"网络化生活"和"地球村文化"。

In the wild struggle for existence, we want to have something that endures.

在激烈的生存竞争中，我们想获得一些耐受力强的东西。

When grown in the light and with nutrition as the limiting factor, the wild type was less influenced due to its capability of photosynthesis and quickly became predominant over the mutant that has no photosynthetic apparatus. However, when grown heterotrophically in the dark, the mutant remained less competitive than the wild type, showing that the euglenoid proplastids play a role in competition.

在光照情况下，当营养物质成为限制因子时，由于具有光合能力野生型生长受影响较小，在与没有光合器的突变株的竞争中很快地显示出优势；在黑暗中二者均只能以异养方式生长，但突变株仍然处于竞争弱势，显示原质体结构对于生存竞争的作用。

In the ruthless survival competition, the studying of the problem is full of exigent practical significance.

在"优胜劣汰"的生存竞争中对这一课题进行研究有迫切的现实意义。

Gracilis were applied to investigate the effect of proplastid on adaptability, in which such structure was found to be important to the competitiveness during heterotrophic growth in the dark; 2 a new procedure for differential display technology was developed and used to study the influence of plastid on nuclear gene expression, with which it was shown that the loss of plastid could cause remarkable changes in expression of certain nuclear genes.

本文主要有两点突出之处：1）应用裸藻褪色突变株与野生型的生长竞争实验探讨了原质体对于裸藻的适应意义，发现在黑暗环境和异养生长条件下原质体对于细胞的生存竞争有重要作用；2）改进了一种差异显示技术并利用该技术来研究质体的有无对基因表达的影响，证明质体丢失可导致某些核基因表达的显著变化。

It was not forced upon them by the survival competition; they could have caught and lived on prey without using poison, just as the thousands of non-poisonous snakes still do.

素液不是生存竞争强加给它们的，它们也可以不用素液捕捉动物而生存，就像今天成千上万的无毒蛇那样。

It was not forced upon them by the survival competition;they could have caught and lived on prey without using poison,just as the thousands of non-poisonous snakes still do.

毒液不是生存竞争强加给它们的，它们也可以不用毒液捕捉动物而生存，就像今天成千上万的无毒蛇那样。

The Hegyi single-tree competition index also showed there was in-tense competition between Bruguiera gymnorrhiza and Rhizophora slylosa to survive. And it could be prognosticated that Bruguiera gymnorrhiza and Rhizophora slylosa will live together for a long time, while Bruguiera gymnorrhiza will have a little superiority during this competition.

结果表明，木榄和红海榄有极其相似的生态位宽度和极高的生态位重叠关系，Hegyi竞争指数模型计算的竞争强度也证明，木榄和红海榄之间存在有激烈的生存竞争，并预测到木榄和红海榄将长期共存，但木榄在竞争中有微弱的优势。

They both saw what Lamarck had failed to, that the struggle for existence in a crowded world, with its winners and losers, was the force that would ensure the survival of the plants and animals carrying the best traits.

他们都看到了拉马克观点的不足之处并提出了合理的解释：确保生物在这个星球上生存以及自身携带最优秀特质的是通过你死我活般的生存竞争实现的。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
