蒸发器芯层内气液界面的波动原因

毛细抽吸两相回路（CPL）在正常稳态工作时，其蒸发器主要以芯层表面蒸发的方式传热。在此基础上，给出了多孔芯传热的三层模型，并提出等厚气膜薄层模型，分析了气液界面的形状及引起气液界面波动的原因。通过分析得出，蒸气在薄层内的流动阻力主要由芯层本身的特性来决定，而蒸气薄层厚度的精确值对其影响并不大。     

The resistances of several types of overlaying materials against cigarette burn,scratch, and abrasion

The application of particleboard involves specific qualities that the crude particleboard does not have. All particleboards are not suitable for all applications, especially boards destined for the furniture. Panels should have resistance to scratch, abrasion, and cigarette burns. Therefore, panels are suggested to be coated with overlays for furniture or paneling. In this study, effects of type of overlay, weight of raw decor paper, thickness and type of veneer, and thickness of continuous press laminate (CPL) on the resistances to cigarette burns, scratch and abrasion were investigated. The highest scratch and abrasion resistances were obtained from CPL-coated particleboards while the boards coated with lacquered paint had the lowest values. The results showed that while the raw paper weight, CPL and veneer thickness and type of veneer did not affect the properties, type of surface coating material was found to be effective on the properties. It was stated that CPL was resistant to the cigarette burns, while the other overlays were not.

Personalization of internet telephony services for presence with SIP and extended CPL

This paper discusses issues of personalization of presence services in the context of Internet Telephony. Such services take into consideration the willingness and ability of a user to communicate in a network, as well as possibly other factors such as time, address, etc. Via a three-layer service architecture for communications in the session initiation protocol (SIP) standard, presence system basic services and personalized services (personal policies) are clearly separated and discussed. To enrich presence related services, presence information is illustratively extended from the well known “online” and “offline” indicators to a much broader meaning that includes “location”, “lineStatus”, “role”, “availability”, etc. Based on this, the call processing language (CPL) is extended in order to describe presence related personalized services for both call processing systems and presence systems using information such as a person’s presence status, time, address, language, or any of their combinations. A web-based system is designed and implemented to simulate these advanced services. In the implementation, personal policies are programmed by end users via a graphic user interface (GUI) and are automatically translated into extended CPL. The simulation system clearly displays when, where and what CPL policies should be used for the provision of personalized presence services and call processing services. Policy conflicts are also addressed by setting policy priorities in the system.

Emergent Nonreciprocal Circularly Polarized Emission from an Organic Thin Film

Controlling circularly polarized (CP) emission is key for both fundamental understanding and applications in the field of chiral photonics and electronics. Here, a completely new way to achieve this goal is presented. A luminescent thin film, made from a chiral conjugated phenylene bis-thiophenylpropynone able to self-assemble into ordered structures, emits highly circularly polarized light with opposite handedness from its two opposite faces. Such emergent nonreciprocal behavior in CP emission, so far unprecedented, represents a fundamental advance, opening new opportunities in design, preparation, and applications of CP emitting materials.

木瓜脂肪酶规模化制备及其酶解奶油的风味分析

木瓜乳中含有丰富的酶类,其中木瓜脂肪酶（Carica papaya lipase,CPL）作为天然固定化酶备受关注。目前尚无规模化制备CPL的工艺报道,限制了其在工业上的应用。本文通过板框过滤分离木瓜乳中的木瓜蛋白酶和木瓜脂肪酶,然后通过喷雾干燥规模化制备CPL,并优化了喷雾干燥的物料入口温度。在最优的入口温度135 ℃条件下,CPL的得率为4.12%,脂肪酶回收率为88.53%,比酶活为167.60 U/g。研究考察了CPL的酶学性质。结果表明,CPL水解甘油三酯的最适反应pH为9.0,最适反应温度为45 ℃。基于CPL对甘油三酯的水解特性将其作为催化剂酶解奶油制备奶味香基。感官分析结果表明制备的酶解奶油酸味和奶酪味突出,风味独特。固相微萃取-气相色谱质谱联用分析得到其酸含量为总挥发物质的73.28%。该酶制剂制备方法可以大规模高效的制备CPL,获得的CPL可以作为制备奶味香基的生物催化剂。
