Based on different thickness hydroxylation content in quartz sample, the changes of Hydroxyl peak 3675cm^(-1 intensity is obvious of different thickness in quartz sample, and withe increase of Quartz plate thickness, the hydroxyl peak transmittance increases.

通过对石英样品中不同厚度羟基含量分析得出，对于不同厚度的石英样品，羟基峰（3675cm^(-1)左右）的强度变化十分明显，石英片厚度的增加，羟基峰的透射率增大。

The results show that carefully controlling of deposition conditions and final polishing of the specimens enable us to deposit antireflective infrared diamond coatings on silicon substrate. In order to investigate the thermal properties of diamond coatings nondestructive photo-thermal radiometry method is used with computer simulation and data analysis to get thermal diffusivity and conductivity of the specimens.

From 1959 to 1976,45 lunar explorers were successfully sent to explore the Moon by USA and USSR,and 382 kg samples of the lunar rocks and regolith were sent bact to the Earth.

1959年至1976年的18年是人类第一次月球探测高潮，美国和前苏联共成功发射了45个月球探测器，获取了382kg的月球岩石和月壤样品，这些探测资料和月球样品的系统分析与研究，大大促进了人类对月球、地球和太阳系的认识，并带动了一系列基础科学的创新，促进了一系列应用科学的发展。

Morphology and photoluminescence investigation are disclosed that there exist strong correlation between the characteristics of the surface morphology and PL, i.e., the samples prepared with lower Ni~(2 ) concentration are exhibited more regular surface morphology, stronger PL, as well as narrower PL band.

实验表明，样品的表面形貌与其光致发光特性之间存在强烈的关联：采用具有较低Ni~(2 )浓度的腐蚀液所制备的样品表面形貌更为均匀，并具有相对较强的发光和较窄的发光峰。

The results showed that the determined components are homogenous on different position of sample surface and in different depth of the sample, and the repeatablity of determination resuts was also good under same preparation conditions. So this way could surmount the error from the sample preparation of powder press.

试验结果表明，块状样品表面不同部位及不同深度的化学成分分布均匀，相同熔融条件下的样品重复性良好，解决了用粉末压片制样对测定结果带来的误差。

This paper isolated and identified Listeria monocytogenes by the first step of the physiologic and biochemical tests from 1627 samples. 1627 random samples from 9 sorts of quick-frozen food, aquatic products, resh meat, meat protucts, fruit, vegetables, bean product, raw milk, salted product were collected from supermarkets and peasant-trade mart and some faeces of animal and person. The total detectable rate of Listeria monocytogenes was 14.5%. The results showed that the detectable rate of Listeria monocytogenes were higher. It expressed that pollution level of Listeria monocytogenes in Baoding and circumjacent area was taller.

本文对采自速冻食品、水产品、生肉、熟肉制品、水果、蔬菜、豆制品、奶及奶制品、腌制品等9类食品及动物粪便和人源粪便共1627份样品进行了单增李斯特菌的分离与鉴定，单增李斯特菌的总检出率为14.5%，表明单增李斯特菌的检出率偏高，在9类食品样品中，生肉中单增李斯特菌的检出率最高，高达27.4%，其次是水产品，检出率为24.7%，应引起高度重视，以免引起食源性疾病的暴发。

The following conclusions have been reached, milk has an obvious absorption in the mid-infrared band, and the locations of the absorption peak are consistent with the attributes of molecule functional group analysis and the information from FOSS Company; the effects of the factors on the repeatability are below 3‰; For the quantitative analysis, the method of factorial design is applied to optimize the calibration set. The outliers are determined considering the residual variance distribution. The correlations are 0.990 and 0.986 for fat and protein, respectively. The Root Mean of Square Error of Prediction is 0.121 and 0.111 for fat and protein, respectively. With the application of the methods of wavelengths selection, the numbers of wavelength is decreased greatly from 3301 to 100. The speed is accelerated and the accuracy of the calibration is improved to some extent.

结果表明：牛奶在中红外的吸收特性明显，吸收峰的位置与分子结构的谱带归属以及乳品分析仪器的成功厂商FOSS公司提供的资料基本一致；各种因素对光谱测量影响的CV值基本可以控制在3‰以下；在定量检测中，通过析因设计方法优选校正集样品，结合样品的残差图确定奇异点，脂肪模型和蛋白模型的相关系数分别为0.990和0.986，预测均方根误差分别为0.121和0.111，而在采用波长选择对模型进行优化后，波长从3301个减为100个以内，加快了运算的速度，同时还在一定程度上提高了模型的精度。
