The authors have proposed a new classification scheme for the division and correlation of the stratigraphic systems on the basis of lithology and vertical fossil distribution in the Silurian and Lower Devonian strata in the study area.

笔者详细记述了稗子田志留系至下泥盆统下部剖面的岩性特征和生物化石的垂直分布状况，在此基础上建立和完善区内新的地层系统，提出地层划分的对比依据和建议。

But Volvox shows the sort of thing to look for: a gene that stops reproduction in single-celled creatures and has been co-opted to do a new job.

但团藻提示了我们应该寻找的东西：即一个能阻止单细胞生物繁殖又被指定了新任务的基因。

Results show that this Co-degradation technology provides a new way for corn stalk's use.

结果表明，酶菌共降解为玉米秸秆的生物利用提供了一种新方法。

Studies on impact-related minerals, geochemical anomalies, impact microspherules and microtektites enable us to define frequencies, magnitudes and types of impact bodies of extraterrestrial impact events. Impact layers and ejectas may not only provide distinct event markers in high-resolution stratigraphical correlation, but also potential interpretations for the catastrophic changes and their causes of life and global environment.

通过对撞击地层层序的时空变化、所包含的撞击成因矿物、撞击微球粒和微玻璃陨石以及古生物和地球化学异常等的研究，可以了解撞击事件的发生频率、幅度和撞击天体的性质等，也为探索生物和地球环境的灾难性变化及其起因提供了新的思路。

The objective of this study is to picture the signal tranduction pathway of apoptosis induced by MC so as to further investigate the impact of MC on transcription, expression and regulation of apoptosis gene and the related biological effects; illustrate the toxicological mechanism of MC; as well as discover the new biomarkers invovled.

本研究工作的目的是通过功能基因组分析的技术平台，探讨微囊藻毒素诱导肝组织细胞凋亡的信号转导通路，以便在此基础上，进一步深入研究该毒素对凋亡功能基因在转录、表达、调控水平上的影响，及由此引发的生物学效应；揭示微囊藻毒素的凋亡毒理机制，同时发现新的生物标记物。

ABSTRACT: Tissue engineering, a concept proposed at the end of the 80s of last century, is a newly rising subdiscipline that intergrates several subjects such as biomedicine and material science.

"组织工程"是上世纪80年代正式提出来的新概念。它是生物医学和材料科学多学科交叉融合的新兴分支学科。

The journal publishes papers on the interrelationship between the experimental and environmental sciences, the results of original research or new investigations into the changing situation in which subsistence agriculture, closely controlled by its physical and biological environments, improvement of farming, indigenous economics associated with rural sociology, and the practice of tropical agronomy and animal husbandry.

杂志主要刊载论文，内容涉及实验科学与环境科学的相互关系，原始研究的结果或对由物理和生物环境严格控制的少有余粮的农场经营方式的处境改变的新研究，畜牧改善，与田园社会学相关的本土经济，以及热带农学和动物管理的实践。

The main metabolic pathway used in the production of ALA is C4 pathway with glycine and succinate as precursors.

基于生物体内四碳途径的微生物生产法是合成ALA的新技术。

A new family of sulfonate surfactants, in which the sulfonyl group is attached to one of the alkyl chains, has gained interest owing to their biodegradability, low sensitivity to water hardness, foaming ability, and lower skin irritability than the conventional alkylbenzene sulfonate.

一个新家庭的盐表面活性剂，sulfonyl集团隶属于链条之一，已获得利息烷基是由于它们生物降解性、低敏感性对储层水硬度、发泡能力和较低的皮肤过敏性比传统的烷基苯磺酸盐黄。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
