English Strong and Weak Forms in Connected Speech and Their Application in Middle School English Teaching

英语语流中的强、弱式及其在中学英语听、说教学中的应用

This paper presented a syllable segmentation method for Chinese connected speech.

本文提出一种汉语语音连接词音节分割方法。

The recognition process needed scanning the whole images once and connected domain queue twice.

整个识别过程只需扫描一遍图像和两遍连通域队列。

Then the connected domain computational method is given.

给出了连通域的计算方法。

In the locating process, multiple frames difference is used to get the row position, and connected domain is used to get the column position, the combination of the results is the finally locating result.

在定位过程中，通过多帧差异累加算法获得声级计读数的行坐标，并通过连通域分析获得声级计读数的列坐标，最终将坐标组合得到定位结果。

According to the calculation results of connected domain number, the judgment of the distress image type can be completed.

本文根据连通域数目的计算结果，完成了破损图像类型的判断。

In this article, we introduce maximal connected subgraphs, maximal clique and perfect match of graph theory in biology especially in the study of protein structure research applications.

本文介绍了最大连通子图、最大团和完美匹配等图论知识在生物学尤其在研究蛋白质结构研究方面的应用。

It was shown by practical example that high connate water saturation had considerable effect on well test analysis results, greatly lowering the explained permeability and amplifying formation damage of gas wells.

结果表明：较大量共生水的存在，将对试井解释结果产生较大影响，引起渗透率的较大降低和加深对气井储层的伤害。

These characteristics indicate that the ore-forming fluid resulted from fractional crystallization of magma, with the participation of some connate water at the late stage.

根据这些特征可推断出成矿流体源于花岗岩浆的结晶分异，晚期有少量建造水混入。

Hydrogen and oxygen isotope composition of water in fluid inclusions indicates that ore-bearing hydrothermal solution origined mainly from atmospheric water or deep connate water.

矿物流体包裹体成分反映了两种不同性质热液的活动，氢、氧同位素组成所指示的成矿热水以大气水或地下热卤水为主。

Due to the variation of geologic environment reservoir is often invaded by external water, thus, resulting in the property difference between connate water and formation water.

油藏形成后，由于地质环境变化，储层往往会受到外部水系的侵入，从而造成原生水和水层地层水性质的差异。

Well test data of such reservoirs are hard to analyze by conventional well test models, which should be properly modified when the connate water saturation is high.

用常规的试井模型难以分析这种凝析气藏的试井测试资料。当气井共生水含量较大时，应对原来的试井解释模型与方法进行修正。

In1941, Klinkenberg proposed that the slippage effect would occur when natural gas flow through porous media in absence of connate water.

科林贝尔在1941年提出了气体在不含束缚水多孔介质中渗流时出现的滑脱现象。

In a word, the effect of connate water and stress sensitivity on development of low-permeability gas reservoir should be paid enough attention.

共生水的存在以及应力敏感性对低渗气田开发的影响应引起足够的重视。

Tried to conjure away the doubts that beset her.

设法除去她心中的疑虑。
