He results of TPR and 18O-isotope exchange experiments demonstrated that the excellent activity of Pd/2Ti-3Al was due to its high oxygen mobility and moderate reducibility, which is in accordance with our previous work.

PR和18O同位素交换的结果表明Pd/2Ti-3Al高的催化甲烷燃烧活性是由于其高的氧交换活性和适中的还原性，这也符合我们前面工作中的结论。

Comparing to temperature changing and gas-washing, pressure changing is the most important factor that induces regular fractionation of carbon isotope of gas (variation ofδ 13C is up to 1.3‰).

研究这种变化不仅对油气成藏研究有重要的意义，而且有助于对现今油气性质和组成提供一种全新的成因解释。

This review focused on the transformation of SOC by three typical soil-feeding macrofauna, termite (Isoptera: Termitidae), rose beetle larva (Coleoptera: Scarabaeidae) and earthworm (Oligochaeta: Lumbricidae), using 14C isotope tracer technique. The microbial activities related to the transformation processes are also discussed.

本文综述了3种典型土食性大型土壤动物，白蚁(Isoptera： Termitidae)、甲虫幼虫(Coleoptera： Scarabaeidae)和蚯蚓(Oligochaeta： Lumbricidae)，对土壤稳态有机C降解转化的14^C示踪研究结果及相关的微生物作用。

Results demonstrate that climate fluctuations recorded by the two boreholes correspond to the marine oxygen isotope stages. Thick layer of coarser grained fluvial deposits and the third layer of "hard mud" were deposited in the study area during MIS 6, reflecting a cold climate. The sediments became fine-grained and indicate a coastal marsh depositional environment during MIS 5. The second layer of "hard mud" was deposited during MIS 4. Fine-grained coastal marsh deposits dominated in the study area during early MIS 3, while lagoon-beach ridges prevailed during middle and late MIS 3, forming a layer of silt and fine sand in the coastal plain. The MIS 2 strata are composed of a typical sedimentary sequence with coarse grain in the lower section and fine grain in the upper section, i. e. yellowish grey or brownish yellow silt and brownish yellow or dark green "hard mud", respectively.

研究结果显示，两孔记录的古气候波动可与深海氧同位素曲线进行对比：对应于深海氧同位素曲线第6阶段(MIS6)，堆积厚层的河道相粗颗粒沉积及第3硬土层，反映当时气候寒冷；第5阶段(MIS5)，为滨海湖沼沉积，沉积物的颗粒显著变细；第4阶段(MIS4)，本区形成第2硬土层；第3阶段(MIS3)的早期，本区也发育滨海湖沼沉积，中晚期则形成潟湖—砂坝体系，在滨海平原区普遍发育粉、细砂层；第2阶段(MIS2)，地层由下粗上细的沉积序列构成，下部为黄灰、棕黄色粉砂，上部则为棕黄色或暗绿色硬粘土。
