Carcinoma of the salivary gland is an uncommon disease, accounting for less than 1% of all head and neck malignant neoplasm.1 Lymphoepthelioma is a malignant tumor of epithelial origin showing varying amounts of reactive lymphocytic infiltrate. Lymphoepithelioma-like carcinoma （LELC） constitutes a significant proportion of salivary gland carcinoma in Chinese and Eskimo populations and is related to Epstein-Barr virus infection. Carcinoma of the salivary gland has a propensity for early lymphatic metastasis, and thus a swelling of cervical lymph nodes is occasionally the sole initial symptom. It is very vital to consider a multimodality approach including surgery, radiotherapy and chemotherapy for the treatment in the locally advanced disease.

基于光电接收目标的漫反射光原理,采用红外激光探测室内声波,在对目标特性研究和漫反射回波信号光功率估算的基础上,设计和研制了实验系统。用红外激光探测从玻璃目标返回带有受声波调制的激光漫反射回波信号,在6-63 m距离及直接反射光线与探测器光轴之间的夹角β≤±4°时,可以听见所探测到回波信号中的声音;当β=4°-15°时,可以探测到激光漫反射回波信号,但听不到声音。实验证明,利用漫反射激光探测室内声音的方法是可行的。

目的在羧甲基纤维素钠(CMC-Na)与壳聚糖(CS)基材中添加纳米蒙脱土(MMT),制备安全无毒、具有良好吸水性的海绵衬垫,可用于鲜肉的保鲜包装。方法将不同比例的MMT添加到CMC-Na和CS混合溶液中,冻干后采用氯化钙交联得到海绵衬垫,测定衬垫在水中的溶胀率和可溶物含量以优化配比,然后测定最优衬垫的吸湿速率、红外光谱、形貌、压缩强度以及色差等。结果当MMT质量分数为5%时,衬垫在水中的溶胀率最高,可溶物含量较低,且与空白对照品相比,由于MMT在高分子基材表面形成大量微米级团聚粒子,所以其比表面积增大,吸湿速率加快。同时,由于MMT良好的力学强度,且与CMC-Na和CS基材结合良好,因此MMT的添加大大提高了衬垫的压缩强度。加入MMT后,虽衬垫的颜色有所加深,但肉眼观察并不明显。结论 MMT的加入可改善CMC-Na/CS衬垫的性能,促进其在鲜肉包装中的实际应用。

随着我国经济的不断发展,人们对于矿山建设的要求也不断提高。在现代的各种矿山开发建设中,矿山地质测绘技术也越来越得到了人们的重视。测绘技术作为仪器矿山地质最初的起点,测绘的精度直接影响到了矿山工程从规划到施工的方方面面。可以说,如果在矿山地质工程的建设过程中,测绘工作没有做到位,那么我们的矿山地质工程的质量就很难得到保障。测绘工程一般可以简单的理解为测量和绘图两个相互独立有着密切联系的过程,这两个过程当中都有着不同的技术。我们将对这些技术进行一下简单的介绍。
