演化地

According to the evolution characteristics of organic matter, paleogeotemperature and porous media nature, diagenetic environments can be divided into two types, i.e, acidic and alkalic ones.

根据有机质演化特征、古地温和孔隙介质的酸碱性特征，可将其划分为酸性和碱性两种成岩环境。

The relatively rapid complexification in most recent geological history suggests to Brooks "that problem solving behavior, language, expert knowledge and reason, are all pretty simple once the essence of being and reacting are available."

在地质学史上，复杂性在近代有了较快的发展。这使布鲁克斯想到：一旦具备了生命和对外界做出反应的基本条件，就可以轻而易举地演化出解决问题、创造语言、发展专业知识和进行推理等高级智能。

Cu metallogeny at the platform period was mainly related to carbonate rock annd sandy conglomeratic clastic rock formation during transgression at the initial stable platform stage and clastic rock and volcanic formations in the.

扬子壳块西缘云南段在晚震旦世—三叠纪处于相对稳定的地台演化阶段，但局部地段的拉张裂陷作用至少在早奥陶世开始，断续延续到三叠纪。

Furthermore, in order to improve the interpretation of the deltaic sedimentary record, e.g., to identify climate and environmental changes using the record, the various parameters derived from analyses of the cores should be standardized by evaluating the temporal changes caused by early diagenesis and decay, and by determining the rate of deltaic shoreline changes which control the relative position of the record within the deltaic sedimentary system.

此外，在长江三角洲沉积记录的分析方面，为了更好地提取气候、环境演化信息，应充分考虑沉积记录形成后所经历的自身变化（如成岩作用变化、分解和衰变等）和相对于岸线迁移的空间位置变化。

At the same time, the plane distribution of diagenetic facies is concluded, and then pore evolepment of different microfacies is contrasted.

其次，在沉积相、微相研究的基础上，结合大量薄片及地化等资料，进行了成岩作用、成岩阶段、成岩环境及成岩序列的研究，确定了成岩相的平面展布，最后探讨了不同微相的孔隙演化过程。

The tidal flats include dolomitic flat, limemud flat and dolomitic-limemud flat, whereas the open platform mainly consists of grain banks and reefs.

其中，潮坪环境包括云坪、灰坪、灰云坪等，而开阔臺地环境为各种颗粒滩和生物礁。环境的演化反映了从早到晚海水逐渐加深的过程。

The trend of literary thought of new period is rich and colorful and is placed in durative evolvement.

新时期的文艺思潮，是多元共生、丰富多姿的；同时它也在不断地演化。

Based on the achievements and developm ents in studying natural gas hydrates at home and abroad,the mechanism of causi ng the oil and gas reservoirs to be tightly sealed by the natural gas hydrates i s systematically analyzed in the paper through discussing the formation mechani sms,evolution properties and distribution laws of the natural gas hydrates.In li ght of the research on their control effects on petroleum accum ulation and reservoir preservation,several geologic models of oil and gas accumu lation and preservation related to the natural gas hydrates are proposed,such as vertically and laterally screened models,screened-by-drape and screened-by- contact models and syngenetically and epigenetically screened models,etc.

以国内外天然气水合物的研究成果和进展为基础，通过讨论天然气水合物的形成机制、演化特征以及其分布规律，系统分析了天然气水合物可以得天独厚地封盖油气藏的机理，探讨了其对油气藏尤其是气藏聚集和保存的控制作用，提出了天然气水合物聚集和保存油气的多类地质模式，如垂向遮挡和侧向遮挡、披覆遮挡和接触遮挡以及同生遮挡和后生遮挡等。

That was three years ago, when few were probably aware of how quickly a technology known as "evolvable hardware" was emerging from the shadows.

那是在三年之前，少数人大概意识到被称为&可演化硬件&技术在走出束缚，其发展是多么地迅速。

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