在1.4中，我们在最一般条件假设下，给出了Hilbert空间上线性有界算子及其最小二乘解的误差分析，从而完整地解决了Hilbert空间算子的扰动理论。

Thermal exposured at 175 ℃ for 100 h and 500 h, the yield strength decreases by 5.5% and 14%, and the elongation decreases by 4% and 9.3%, respectively. The fact that S′(Al2CuMg) precipitates get coarsen and the precipitate-free-zones get wider are responsible for the decline of the tensile properties of 2124-T851 aluminum alloy under thermal exposure condition.

于175 ℃热暴露500 h屈服强度和伸长率就分别降低14%和9%；于热暴露条件下，2124-T851合金拉伸性能衰退的主要原因是合金固溶体基体内主要强化相S′(Al2CuMg)相粗化以及晶界无沉淀析出带的宽化。

The model system is in the generalized curvilinear coordinates, using high precision self-adaptive grids to fit the complicated topographies and coastal shapes.

模型系统采用广义曲线坐标系下的形式，使用高精度的自适应网格拟合复杂岸界。

Addition of Nb causes more dispersed distribution ofη phase along grain boundaries and therefore results in higher high temperature ductility.

通过在合金中添加Nb，可以在晶界上析出更为弥散的η相，从而使得合金在高温下获得相当高的塑性。

We consider the Xijinwulan- Jinshajiang suture as an additional Indosinian suture which developed within the Yangtze plate. The Bangong Co-Nujiang and Yarlung Zangbo sutures developed within the Gondwanaland domain, but neither can be con- sidered to define the northern boundary of Gondwanaland.

西金鸟兰-金沙江缝合带是发育在扬子板块内部的印支期缝合带，班公湖～怒江和印度河一雅鲁藏布江缝合带是发育在冈瓦纳大陆框架下新特提斯阶段的缝合带，构不成冈瓦纳北界。
