Compared with the initial value problems of scalar conservation laws with smooth flux function, the global weak entropy solutions for the initial-boundary value problems of scalar conservation laws with weak discontinuous flux function include the following new interaction types: a rarefaction wave collides with the boundary and is absorbed compltetely or partially by the boundary; a rarefaction wave collides with the boundary and the boundary will reflect a contact or non-contact shock wave; a contact or non-contact shock wave collides with the boundary and is absorbed by the boundary; a contact or non-contact shock wave collides with the boundary and a new non-contact shock will rebound from the boundary simultaneously or later.

A reflection type diffraction grating according to the present invention has a structure in which a metal film as a first layer with reflectance not lower than 30 % with respect to the wavelength of incident light and a transparent dielectric film as a second layer are laminated successively on the surface of the reflection type diffraction grating.

According to the simulated results, it was found that the incident light was not fully absorbed in the solar cell due to a thinner base layer. The un-absorbed incident light could be further reflected by a AuGe/Au mirror layer and absorbed again by the base layer. Thus the disadvantage of the GaAs thin-film cell with a thinner base layer could be solved by the additional reflection from the AuGe/Au mirror with a high reflectivity within 800~1000 nm wavelength. Moreover, the external quantum efficiency in the long wavelength region and short current density were also increased.

从模拟结果中得知，薄膜型结构之太阳电池可以经由AuGe/Au之金属反射层，再次将未被基极层完全吸收之入射光反射回太阳电池，使得薄膜型结构在长波段的外部量子效率获得提升，这结果显示薄膜型结构太阳电池可利用AuGe/Au之金属反射层在长波段的高反射率，改善使用较薄基极层时，无法将入射光完全吸收的缺点。

The patient was a 66-year-old male who presented with paraparesis. On examination, strength was 5/5 in both upper extremities and 3-4/5 in both lower extremities. Pricking sensation was relatively retarded below the sixth thoracic vertebra on both sides. Fine-touch sensation was limited below the ninth thoracic vertebra on the right side and below the eleventh thoracic vertebra on the left side. Responses to vibration and joint position sense were well preserved. Deep tendon reflexes were increased in his legs. He had voluntary anal contraction and preserved anal and bulbocavernous reflexes. MRI revealed dissection of the descending aorta from T4 to T10 levels with thrombus present in the false lumen, and the thoracic cord was marked atrophy, especially from T6 to T8 levels. To the best of our knowledge, no such case had been reported so far.

这是一位66岁的男性病患，到院时以下半身轻截瘫来表现，检查后发现其双上肢肌力为5/5而双下肢肌力则为3-4/5，刺痛觉在两侧第六胸椎以下异常，轻触觉在右侧第九胸椎与左侧第十一胸椎以下异常，震动觉与本体感觉则皆属正常，深肌腱反射在两下肢均有异常增强的情形，肛门的主动收缩正常且肛门反射与球体海绵体肌反射均正常，核磁共振影像显示降主动脉在T4到T10处有剥离的情形并於伪腔内发现血栓，此外，病患之胸部脊髓则有明显萎缩的现象，以T6到T8处最为明显，就目前可见的文献资料，并无类似的报告被提出。

Well, if you have a laser busily reading the disc, there's obviously going to be quite a bit of reflection and scattering of the signal, and if it's reflected off anything back in phase with the signal that's going on it just mucks the signal up.

嗯，如果雷射头忙著读取光碟，很明显讯号就会有很多反射跟散射，而如果反射讯号又折回跟传输中讯号同相位那讯号就会被搞乱E所以光亮及具反射性的表面很容易破坏整件事，所以必须以能吸收红外线的漆来尽量控制这种情况

The Gran Telescopic, who made his first experimental observations in 2007 with half the capacity, now opened, receives the light coming from space in its gigantic reflector mirror, segmented by 36 hexagonal pieces of glass and ceramic, totally controlled by a newly -developed control system called active-optics's, which makes all the pieces work together as a single glass reflector.
