摘要： A method of preparing and rapidly curing a composite material having a thin cross section. The composite material includes a mixture of solid particles, at least some of which are a material that reacts with CO2, such as a silicate, for example Wollastonite. The green material is prepared by mixing the solid components with a liquid such as water to form a slurry, and forming green bodies by placing the slurry in forms. The green bodies are reacted with CO2 to form cured composite materials having thin sections, in the range of 10 to 15 mm. Curing in periods of 6 hours has been demonstrated.

摘要： A process for forming ultrathin dense-layer asymmetric hollow fiber membranes with a dense layer of less than 500 .ANG. from a binary solution system comprising a polymer and a solvent. In this process, the spinning polymeric solution has a high viscosity and exhibits chain entanglement at the spinning temperature. The solubility parameter difference between the bore fluid and the spinning dope is less than 2.5 (cal/cm.sup.3).sup.0.5 and the volume ratio of bore-fluid flow rate to the dope flow rate is between 0.45 to 0.75. The dope is wet-spun into hollow fibers using water as external coagulant. The ultrathin dense-layer asymmetric hollow fiber membranes are suitable for air and other gas separations.

摘要： In current practice, quantitative traffic data is most commonly acquired from inductive loops. In addition, video-image processing or time-of-flight laser systems can be used. These methods all have problems associated with them. Therefore, we have developed a new type of non-intrusive laser-based detection system for measurement of vehicle travel time. The system employs a fan angle laser, an image lens, a set of cylindrical optics, a linear photodetector array, and associated signal processing hardware and software. The system is positioned above the plane of detection and configured such that it can unambiguously find the object boundaries in all lighting conditions independent of the time-of-flight of the laser. Instead of depending upon the reflectance of the object being detected, or determination of the range or distance from the detector to the object being detected, the invention reflects the laser off of the pavement or other roadway surface. The lack of a reflection determines the size, shape, and “presence” of the vehicle, and the system is capable of determining the length and width of moving objects, as well as travel time, in real time with high resolution.
摘要翻译：在目前的实践中，定量交通数据最常见于电感回路。此外，可以使用视频图像处理或飞行时间激光系统。这些方法都有与之相关的问题。因此，我们开发了一种新型的非侵入式激光检测系统，用于测量车辆行驶时间。该系统采用扇形角激光器，图像透镜，一组圆柱形光学器件，线性光电检测器阵列以及相关的信号处理硬件和软件。该系统位于检测平面之上并且被配置为使得它能够明确地在所有照明条件下找到与激光器的飞行时间无关的物体边界。本发明不依赖于被检测物体的反射率，或者确定从检测器到被检测物体的距离或距离，反射了路面或其他道路表面上的激光。缺乏反射决定了车辆的尺寸，形状和“存在”，并且系统能够以高分辨率实时地确定移动物体的长度和宽度以及行驶时间。
