Therefore, it is of great importance to investigate the photolytic behavior of POP in the environment.

由于持久性有机污染物在环境中难以被生物降解，因此研究POP的光化学行为对于POP的环境行为评价有重要的意义。

Tissue engineering is a multidisciplinary science merging with cell biology, material science, engineering and chemistry. Its basic idea is to expand a number of cells in vitro and seed them on a polysynthetic biodegradable polymer structure, and finally enable the organization of 3-dimmentional and functional tissues or organs.

组织工程技术是融合了细胞生物学、材料科学、工程学和化学的一门边缘学科，它的基本思想是用少量组织细胞经体外培养扩增后播种在可降解的生物支架材料上，再回植入体内形成有功能的组织或器官。

Most of the people inhabiting in Taiwan and Mainland China share the same blood, culture, and customs. This is a firm ground for primordialism and biopsycologialism, both of which help the formation of one national identity.

台湾与中国分居海峡两岸，绝大部分人民有相同的血缘、文化与风俗习惯，如此都是促成凝聚民族认同的「原生论」与「生物心理论」的有力凭藉。

A series of mono-, sesqui-, di- and tri-terpenoids with various structural types, which produced by bio- oxidation, hydrogenation, hydrolyzation, esterification and cyclic cleavage toward-limenone, were analyed by GC-MS.

经GC-MS分析发现该两细菌对-柠檬烯有显著的生物催化转化作用，能对底物进行不同程度的氧化、还原、水解、酯化、开环等反应，并产生丰富的系列结构不同的其它萜类化合物：包括单萜、倍半萜、二萜、以及三萜等。

As an available microbial fertilizer, the classified shap characteristics of photosynthetic bacteria, the applied conditions and applied effects of photosynthetic bacteria on different plants were described and expected in this paper.

摘要作为一种有前景的生物菌肥，本文对光合细菌的分类形态特征、在不同植物上的应用研究现状和应用效果进行了介绍和展望。

It is necessary to carry out a thorough study on pest control technology with DMDS, with an expectation of obtaining a new fumigant of methyl bromide alternative.2. Investigation of the toxicity of fumigation on adult and mixed stages of the three most tolerant insect species -- Sitophilus oryzae, Rhyzopertha dominica and Tribolium castaneum -- under a range of EtF、DMS and DMDS doses in a Flow-through Fumigation System shows that the FTFS procedure offers a constant concentration of fumigant with low CO2 concentrations and ensures that the fumigant toxicity is effectively not compromised by CO2. In comparison with chamber fumigation method, the toxicity data of EtF、DMS and DMDS obtained from this experiment is more accurate by using FTFS.

主要研究结果如下：1、甲酸乙酯和二甲基二硫对仓储害虫具有良好的控制作用，应加快甲酸乙酯替代溴甲烷防治仓储害虫开发应用，同时，二甲基二硫是很有潜力的仓储害虫防治熏蒸剂，要深入进行二甲基二硫控制有害生物的技术研究，以期获得新的溴甲烷替代熏蒸剂。2、利用循环熏蒸系统测定了甲酸乙酯、二甲基二硫和甲硫醚对米象Sitophilus oryzaeL。

The result indicates that there is a good correlation between the distribution of molecular steric and electrostatic field and bioactivity.

结论说明该系列化合物的分子立体场和静电场的分布与生物活性之间有良好的相关性。

TENTACLED monsters, pale skinny humanoids, shimmery beings of pure energy...

据《新科学家》杂志报道，每当说起外星人，我们总是充满想象，脑海中会浮现各种各样的奇异镜头：有触须的猛兽，皮肤苍白、瘦骨嶙峋的类人怪物，以及释放纯净能量、微微发光的生物。

The author concludes his review by asking,"Where is the scientific evidence showing that GM plants/food are toxicologically safe, as assumed by the biotechnology companies?"

作者在评论中用询问作结论：&有哪里的科学证据去证明，正如生物技术公司自己所假设的一样：转基因植物/食物的毒性是安全的呢？&

Implants which were implanted in focus of spinal tuberculosis were safe because they could not cause infection diffusion or formation of tuberculose focus in the local region. Otherwise, the implants had a good biocompatibility to host.

脊柱结核病灶内安放内置物并不引起感染的扩散或者局部形成结核病灶，是安全可行的，与宿主间有良好的生物相容性。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
