The results showed that most multiaxial fatigue cracks were initiated and propagated along the direction of maximum shear plane.

利用扫描电镜对疲劳试样的外表面和疲劳断口进行观察，研究了多轴疲劳裂纹萌生和扩展规律，发现裂纹基本上沿着最大剪切平面萌生和扩展。

The crack growth rate was decreased with crack extension because of the sliding contact of the crack faces.

随着裂纹的扩展，裂纹扩展速率由于裂纹面的滑移接触而减小。

The growth rate of short cracksis faster than those of long ones around the threshold stress intensity.

结果表明，在门槛值附近，对于相同的应力强度因子范围，短裂纹扩展速率比长裂纹扩展快。

As a result, the crack propagation rates and threshold stress intensity factors for crack arrest in air and water were obtained, and revealed anisotropy.

结果表明，恒载荷下，压痕裂纹在空气和水中不断扩展， 120 h后趋于稳定，从而就可获得裂纹扩展速率和裂纹止裂的门槛应力强度因子KISCC，它们均显示各向异性。

The experimental results show that in answering document retrieval of Chinese question answering system, the performance of expanding the query based on related words for specific question types is much better than in unexpanded query.

实验结果说明在汉语问答系统答案文本检索中，按照问题类别关联词进行查询扩展比未进行查询扩展在性能上有很大的改进。

It expanded to 106119ha in 1973, descented to 99167ha in 1987, backed up to 112440ha, and attained the max value in history—123170ha in 1998 and descent to 109934ha again in 2001. GIS overlaying analysis shows that, the spatial change of Minqin Oasis had the different characteristics in different stage in the last 50 years: at the end of 50's to the beginning of 70%, oasis expandation Was performed by extension of origin oasis; the atrophia of oasis from the beginning from 70's to the 80's was performed by increasing of non-oasis spot pieces of inner part for oasis; the main performance of keeping on expanding of oasis from late 80's to late 90's is outside extension of Baqu oasis near the upper stream, with increased oasis area in interior of hungriness and increased area of non-cultivation in Huqu oasis in the north. From 1998 to 2001, opening up wideness in interior of hungriness continued, but hnngrinessization of oasis became worse. The oases in the Minqin Basin developed from small to large and back to small in terms of area changes, and from south to north then to south in terms of spatial changes.

绿洲分布图的GIS叠加覆盖分析表明，近50年来民勤绿洲的空间变化在不同阶段有不同的特征：50年代末至70年代初，绿洲扩展主要表现为已有绿洲的外延式扩大；70年代初至80年代后期的绿洲萎缩，主要表现为绿洲内部非绿洲斑块增加；80年代后期至90年代后期的持续扩展，主要表现为靠近上游的坝区绿洲向外围扩展和荒漠腹地绿洲面积的增加，而北部湖区绿洲弃耕面积不断扩大；98年至2001年，绿洲荒漠腹地的开荒还在继续，但湖区的绿洲荒漠化还在进一步加剧。50年来民勤绿洲的发展总体上经历了一个面积由小到大再到小，空间位置上从南而北再向南的迁移过程。

Starting with the toughening of ceramics, the subcritical crack growth model on monotonical loads was set up for the first time, and the V—K curves in the subcritical crack growth process and the effects on them were obtained by use of computer simulation.

首次从材料增韧入手，建立了单向载荷形式下亚临界裂纹扩展模型，并利用计算机数值计算获得裂纹扩展过程中V—K曲线及其影响因素，由此对多晶陶瓷材料疲劳现象的本质进行了分析。

In order to achieve the goal, the paper extends multicast routing and signaling based on QosNP, and also discusses message extending and building mechanisms which are interrelated with signaling multicast in the field of SUPA.

为实现这一目的，本文在SUPANET服务质量协商基础上对组播路由和信令消息进行了扩展，探讨了SUPA域内与组播信令相关的消息扩展及建树机制。

Meanwhile, phase transition (t-ZrO2 to m-ZrO2) has also been detected by XRD and this behavior toughens the toughness of the composite.

作者在讨论复合材料的裂纹扩展上不够准确，由于图6照片看不到晶粒和晶界，因而不能准确判断裂纹扩展方式。4。
