Studies on impactrelated 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 highresolution 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。

All these researches provide a completely new method for the quantitative demarcation and correlation of sequence stratigraphy.

这些探索将为地层层序的定量划分和对比提供一种新的思路和有效途径。

This paper discusses the research carried out on the Lake Sugan, in the northern margin of Chaidam Basin. The climate and environmental changes in Lake Sugan drainage area over the past 2670 years were studied using the varve dating of the well preserved lamination sediments in core SG03I taken from the center of Lake Sugan, the study of varve formation in modern lake system and modern process study of carbonate and oxygen isotopes of the water within the drainage area, and according to the main index of the stable isotopes of carbonate sediments synthesized other index analysis.

本文以柴达木盆地北缘苏干湖为研究对象，通过对湖泊中心位置SG03I孔保存完好的纹泥沉积物岩芯进行年代学研究，对湖泊现代沉积过程及碳酸盐、流域水体同位素进行现代过程研究，以沉积碳酸盐稳定同位素指标为主，结合其它代用指标的综合分析，探讨苏干湖流域近2670年来的气候与环境变化，综合区域其它记录对苏干湖流域晚全新世气候变化的驱动机制进行探讨，获得如下认识：1、柴达木盆地北缘苏干湖若干钻孔岩芯发现，水深大于3.0m的沉积物均具有裸眼可分辩的由深色层和浅色层组成的纹层层理。

Ecotoxicology of sulfamethazine on soil microbial activity and its degradation and transfer in the soil were investigated.

通过室内培养和土壤薄层层析等实验方法，研究了磺胺二甲嘧啶对土壤微生物的毒性及其在土壤中的降解、迁移特性。

Wind the crosslinked tape onto welded cable cores to certain size when connectingcables, and then use molding model to effect 0.6Mpa air pressure and a temperature of about 160℃ to sulfurate.

接头时用交联带一层层缠绕包覆在焊接好的电缆线芯上达到一定尺寸，再用成型模具加0.6Mpa空气压力、160℃左右高温硫化成型。

Therefore a new methodology on how to syncretize the multi-genre sequence stratigraphy is discussed in this paper.

由此，决定探讨一种方法思路，力求吸取各家之长，总结出一套陆相地层层序地层学研究方法。

Inner layer heterogeneity, plane heterogeneity and microfacies heterogeneity are studied by using heterogeneity parameters: permeability variance coefficient, permeability tantivy coefficient and permeability differential.

应用渗透率的变异系数、突进系数和级差来分析储层层内、平面非均质性与各微相的非均质性。

Thus the public stair opening off the gallery foyer leads directly to the double-height living room on the first floor,while the cylindrical private stair ascends to the library on the second floor and the master suite on the floor above.

因此公共楼梯从大厅走廊直接通向一层的有二层层高的起居室。而圆柱形私人楼梯则通向二层的图书室和顶层的主人套房。

The Sinfonia, an organ Toccata and Fugue, begins in g minor depicting a chaotic and somewhat bitter feeling. The fugue features two main themes in chromatic progression. Both signify and incessant supplication of God. The Sinfonia was dedicated to the Canadian organist, Thomas Fiches, a closed friend of the composer.

整部大合唱的序曲由管风琴的托卡塔在低沉的g小调上开启，演绎出纷乱而痛苦的感觉；一首强力的二重赋格随之而至，以半音的旋法层层展开，表达了向上帝不住的哀求。

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
