倍频光栅的莫尔条纹研究

用傅里叶频谱分析方法研究了横向莫尔条纹中一个光栅倍频时莫尔条纹的变化，论证了倍频光栅形成的莫尔条纹方向与等周期两RoncK光栅形成的莫尔条纹方向相同，其周期与两小周期光栅的莫尔条纹周期相同，其对比度随倍率的增加而减小的特点，呈现莫尔条纹效应的主要是等栅距光栅和二倍频光栅，介绍了产生倍频光栅的一些方法，如采用滤波的方法，消去光栅的0级衍射波，形成倍频光栅；采用球面波照明光栅，形成倍频的光栅的自成像等，举例说明了其应用，这些应用表明二倍频光栅莫尔条纹可使结构紧凑，测量简单，或使分辨率提高一倍。     

分配制度的重大改革--生产要素按贡献参与分配

生产要素按贡献参与分配，这是分配制度的重大改革。生产要素按贡献参与分配是现代经济的客观要求。生产要素按贡献参与分配是一个十分复杂而又全新的课题。必须建立行之有效的具体分配形式。

Development of the CAS-IBB single-particle microbeam for localized irradiation of living cells

A single-particle microbeam facility has been constructed at the Key Laboratory of Ion Beam Bioengineering (LIBB), Chinese Academy of Sciences (CAS). The system was designed to deliver a defined numbers of hydrogen ions, produced by a van de Graaff accelerator, in an energy range of 2.0-3.0 MeV, into an area smaller than that of the nucleus of an individual living cell. The beam is collimated by a borosilicate glass capillary that forms the beam-line exit. An integrated computer program recognizes the cells and locates them one by one over the microbeam exit for irradiation. We present technical details of the CAS-LIBB microbeam facility, particularly on the collimator, hardware, control program, as well as cell irradiation protocols available. Various factors contributing to the targeting and positioning precision are discussed along with accuracy measurement results.     

Experimental Study and Numerical Simulation of the Casting-Forging Complex Near Net Forming of Alternator Claw-pole

As a newly developed precision technology, casting-forging complex near net forming process is utilized to produce complex components with a short lead time, low cost and high precision, thus to accelerate the response speed of the market and enhance the competitive power of products. In this paper, the casting-forging complex near net forming process of alternator claw pole was developed and investigated with a combination of experimental and numerical simulation method. Qualified near net workpiece was manufactured, mechanical parameter and relative field information during the forming process was also obtained. While the alternator claw-pole is processed with this technology, the forming force is small, the process is short and the quality of forgings is perfect. Therefore, the complex casting-forging near net forming process of claw-pole is an energy and material saving technology, which will have a vast developing and application prospect in the future.

Study and Application of Internal Coating Technique to Drag Reduction of the Trunk Pipeline for the West-East Gas Pipeline

Coverage layer coated in the internal wall of pipeline enables the friction drag to be reduced, the throughput and the gas transmission efficiency to be increased, the frequency of pigging and the number of the intermediate compressor station to be reduced, and the power consumption of the compressor to be decreased etc. The drag reduction is a high advanced scientific technique with outstanding economical benefit. The study and application of internal coating technique for drag reduction of 4000km trunk pipeline in West-East gas transmission pipeline (WEGTP) project are described, in which the main points are the drag reduction principle, coating process and the indoor study of this technique with own-decided knowledge property right at home.     

基于银薄膜/荷叶SERS效应直接检测婴儿配方奶粉中三聚氰胺

以天然荷叶为衬底,结合真空磁控溅射法沉积银薄膜,制备出了一种高效的表面增强拉曼散射(SERS)活性基底.研究发现银/荷叶基底对婴儿配方奶粉中掺杂的三聚氰胺(MA)表现出良好的识别能力,而不需作额外的样品预处理.对掺杂不同浓度三聚氰胺的奶粉溶液进行定量分析,在5~50 mg/L质量浓度范围内获得了较好的线性关系(线性相关系数R20.99).根据3σ准则,检测极限估计为1 mg/L.此外,银/荷叶基底具有良好的均匀性和重复性(相对标准偏差为7.64%和10.54%).该方法对婴儿配方奶粉中三聚氰胺的检测具有简单快速、成本低且无损等优点.
