In the case of read-only CDs, the substrate lies directly next to the reflection layer. In the case of a CD-WO, an absorption layer existsbetween the substrate and the reflection layer. This layer can be irreversibly modified through strong thermal influence, which changes the reflection properties of the laser beams.

就只读CD来说，亚层应紧接在反射层之下，而CD-WO中，在亚层和反射层之间还有一个吸收层，这一层在强热的作用下做不可逆修改，因而改变了激光束的反射特点。

This text passes correctly elm two of Daqing oil field is united --One Song unite person who bury oil pipeline scene to live in environment survey and study, is it take a sample test , environmental corrosivity survey , corrosivity measuring of pipeline and assess of soil to excavate, is it cause person who bury pipeline antiseptic layers of invalid main factor to find out , confirm the environmental grade of corrosion of soil according to environmental comprehensive physics and chemistry index of soil, grasp pipeline antiseptic invalid law of layer , study antiseptic layers of resistivity decay law and to influence that negative pole protect, is it suitable for person who bury antiseptic layer of life-span of the pipeline calculate formulae and actual effect criterion model to propose on the basis of this text, illustrate and simply analyse oil field long to fail person who bury antiseptic layer of surplus ability to work of the pipeline, unite for elm two --One Song unite pipeline antiseptic maintenance of layer , is it put forward science rational suggestion to change.

本文通过对大庆油田榆二联——宋一联埋地输油管道所处环境的现场调研、开挖取样化验、环境土壤的腐蚀性勘测、管线的腐蚀性检测和评估，找出引起埋地管道防腐层失效的主要因素，并根据环境土壤的综合理化指标确定该段环境土壤的腐蚀等级，掌握管道防腐层的失效规律，研究防腐层电阻率衰减规律及其对阴极保护的影响，在本文的基础上提出适用于埋地管道防腐层寿命计算公式和失效判据模型，例证和浅析油田长输埋地管道防腐层剩余工作能力，为榆二联——宋一联管道防腐层的维修、更换提出科学合理的建议。

Thermal oxidation treatment can increase the surface hardness and elastic modulus significantly and reduce the E /H ratio of the TC4, which indicate the treatment can enhance the wear resistance of TC4 alloy. Long time treatment can increase the thickness of the oxide layer, but the outside layer is apt to desquamate during the scratching. The oxide layer closing to substrate has better bonding properties, but microcrack forms as a result of high stress loading, which lead the layer to flake off completely.

长时间的高温氧化可以增加氧化层的厚度，但在划擦过程中氧化层发生两次脱落，表明氧化层由外表层和次外层组成，外层结合力差，易发生一次脆性剥落，内层与基体的结合强度较高，但在较大载荷作用下会产生微裂纹，导致氧化层的二次剥落。

During the high-voltage device design, the thick epitaxial layer LDMOS which is compatible with current technology was researched. This device used piecewise VLD and multiple region structure F reduce field layer. The using of the F reduce field layer effectively reduce the surface electric field of the device, shorten the length of its drift region, enlarge the choice of range of the ion implant dose of the P layer, and effectively restrain the disadvantageously affection on the breakdown voltage of the interface charge Qss.
