Taking the eastern sag of the Liaohe basin where coal, oil and gas resources coexist and the Wangying borefield of the Fuxin basin where coalbed gas was first discovered, researched and developed in China as examples, we systematically discuss the control of volcanism on the lateral and vertical distribution of brown coal, flame coal and gas coal in the third member of the Paleogene Shahejie Formation and on the gas source conditions of each coal region. Both the methane released in the process of regional plutonic metamorphism and the additional methane generated by contact metamorphism are calculated. The physical properties and storage capacity of the coal beds changed greatly due to the formation of blackcoal and highlymetamorphosed crevice coal from igneous intrusion. The sealing capacity of intrusions with various occurrences such as dikes is highlighted.

以煤、油、气共生的辽河盆地东部凹陷和我国首次在矿井中发现、研究、开发煤层气藏的阜新盆地王营井田为例，系统地阐述了火山活动在古近系沙河街组三段对褐煤、长焰煤和气煤在平面及垂向分布的控制，进而导致各赋煤区气源条件的不同；估算了王营井田在区域深成变质过程释放甲烷气的基础上，接触变质作用所形成的附加甲烷量；指出由于岩浆侵入形成了天然焦和高变质裂隙煤，使煤层物理性质及储集能力发生了大的变化；强调了岩墙等不同产状的岩浆侵入岩体对煤层气的封闭作用。

Diabetic retinopathy is one of the most serious microvessel complications of diabetes,it is a main cosmopolitan blindness disease. In recent years, with the molecular biology development, the recognition of the mechanism of DR is more profound and consummate. Most researchers consider that hyperglycaemia, polyalcohol inositol metabolism abnormality, changes of hemorrheology, oxidative stress, inflammation/immune system activation, cytokines/growth factors expression or activity change and so on result in DRs onest and development.

糖尿病性视网膜病变(diabetic retinopathy， DR)是糖尿病最严重的微血管并发症之一，也是一种世界性的主要致盲眼病，近年来随着分子生物学方面的研究进展，对DR发病机制的认识进一步深入和完善，认为高血糖、多元醇肌醇代谢异常、血液流变学改变、氧化应激、炎症/免疫系统活化、细胞因子/生长因子表达或活性改变等导致DR的发生发展。

In polyphase power systems with some number of phases other than three, this effect occurs with harmonics of the same multiple.

在多相电力系统以外的一些数量三个阶段进行，这一效应多发生在同一谐波。

In addition, the redox system can, if required, also contain catalytic amounts of a polyvalent metal ion which may occur in a plurality of valency states.

此外，氧化还原系统，若需要，亦可包括催化量的多价金属离子，其可发生在多价状态。

In the faxless '60s, when TVs were still steam-driven and urgent correspondence was carried in the saddlebags of the Pony Express, news of Dylan's doings would often come limping along months after the event.

在信息传递不发达的60年代，电视系统还是蒸汽驱动，加急信件在驿马快递的包里递送，迪伦进展如何的消息常常在事件发生一个月后才跛行着到来（也可以说"断断续续地到来。"

The goal of this thesis is to develop a suit of Forecasting and Early-Warning software system for potato"s Late Blight that can forecast the occurrence time and the trend of potato"s Late Blight so that it can reduce the loss caused by Late Blight to a maximal extent.

本论文的研究目的是建立马铃薯晚疫病的预测预警系统来指导人们对马铃薯晚疫病的感染、发生时间及流行程度、灾变时间进行预测预警，以尽量减少马铃薯晚疫病所带来的损失。

The T cells in nasal polyps express high CD69 and are activated, producing Th1/Th2 mixed cytokines with change of cytokine secretion predomination, probably owing to the formation of microenvironment of the nasal polyps and the mucosa immune system.

鼻息肉组织中的T细胞高度表达CD69分子，处于免疫活化状态，产生Th1/Th2混合模式的细胞因子，与外周血相比Th细胞因子分泌优势发生改变，可能与鼻息肉"微环境"形成及黏膜免疫系统有关。

This thesis is mainly concerned with mechanism of air preheater after-burning and air preheater hot spots detection technique based on image of temperature field.

本文主要研究了电站锅炉空气预热器发生二次燃烧的机理以及基于温度场分布图的空预器热点检测系统。

From these we can by better simulate the human's thoughts that face the se ction when they are on the true graphic picture, and can recite the prehension in the means that human always accept.

由此我们可以更好地阐述人的思维系统在对客观形象的发生过程中所面临的阐释环节，以及在接受经验中对理解的表述。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
