双模主动复合寻的制导技术研究

随着光电干扰、光电侦察技术的发展,现代战争中导弹作战环境变得十分复杂和恶劣。单一寻的模式的导引头难以完成对目标的全面探测和跟踪,必须采用双模或多模复合导引头。文中主要围绕双波段主动雷达导引头展开研究,旨在为远程反舰导弹提供一可行的高性能导引头方案,并进行必要的论证和相应技术研究。     

纳米铜/聚醋酸乙烯酯复合材料的制备与表征

以聚醋酸乙烯酯(PVAc)为配体,与CuC l2在乙醇溶液中进行反应,生成PVAc-Cu(Ⅱ)配合物。合成反应在室温下进行,反应时间以2 h为宜;用电导率法得出PVAc-Cu(Ⅱ)配合物中金属离子与PVAc链节单元CH2CH(OCOCH3)的物质的量之比为1∶4。以次亚磷酸钠为还原剂,在回流条件下对新合成的PVAc-Cu(Ⅱ)配合物进行还原,制得纳米铜/聚醋酸乙烯酯复合材料。IR分析表明:PVAc-Cu(Ⅱ)配合物中PVAc链节中的CH3COO—中的羰基氧提供孤对电子与金属离子Cu(Ⅱ)形成配位键。用透射电子显微镜(TEM)对纳米铜/聚醋酸乙烯酯复合材料进行表征,结果表明,复合材料中铜粒子的粒径在12.5~37.5 nm范围。     

SOS–A sample ordering system for delivering “assay-ready” compound plates for drug screening

Many bottlenecks in drug discovery have been addressed with the advent of new assay and instrument technologies. However, storing and processing chemical compounds for screening remains a challenge for many drug discovery laboratories. Although automated storage and retrieval systems are commercially available for medium to large collections of chemical samples, these samples are usually stored at a central site and are not readily accessible to satellite research labs.Drug discovery relies on the rapid testing of new chemical compounds in relevant biological assays. Therefore, newly synthesized compounds must be readily available in various formats to biologists performing screening assays. Until recently, our compounds were distributed in screw cap vials to assayists who would then manually transfer and dilute each sample in an “assay-ready” compound plate for screening. The vials would then be managed by the individuals in an ad hoc manner.To relieve the assayist from searching for compounds and preparing their own assay-ready compound plates, a newly customized compound storage system with an ordering software application was implemented at our research facility that eliminates these bottlenecks. The system stores and retrieves compounds in 1 mL-mini-tubes or microtiter plates, facilitates compound searching by identifier or structure, orders compounds at varying concentrations in specified wells on 96- or 384-well plates, requests the addition of controls (vehicle or reference compounds), etc. The orders are automatically processed and delivered to the assayist the following day for screening. An overview of our system will demonstrate that we minimize compound waste and ensure compound integrity and availability.

复合生态系统的降雨截留过程模拟

在水文水资源分析计算中，对降雨损失的处理，往往只对蒸散发和土壤下渗量进行计算，忽视了植被的降雨截留损失，这样至少说在理论上是不完善的。因而，在水文分析计算中，准确模拟植被的降雨截留过程，对合理评价水资源量，具有现实意义和理论价值。在系统分析复合生态系统的降雨截留过程的基础上，建立了半理论的复合生态系统截留计算模型，用于小型生态流域模拟降雨截留过程，不仅丰富了水文学的内容，而且完善了降雨损失计算的理论。

Transfer of low nanoliter volumes between microplates using focused acoustics—automation considerations

Acoustic droplet ejection (ADE) gently and precisely aliquots nanoliter and picoliter liquid volumes without any physical contact with the solution being transferred. The technology is very automation-friendly, as it is compatible with conventional microplates. Focused energy from an acoustic transducer induces droplet ejection into an inverted standard microplate. The commercial system transfers low-nanoliter volumes of dimethyl sulfoxide–dissolved compound libraries and thereby enables cell-based assays to be performed in 1536-well plates.
