ORIGINAL PRINT PAINTING RISES WITH POTENTIAL VALUES FOR COLLECTION     

Yang Liao 《中外文化交流(英文版)》2009,(3):11-13

Printing painting usually refers to varieties of painting printed on wood, stone, linoleum, copper and zinc blocks carved by knife or etched by chemicals. China is generally recognized as the inventor of printing painting, but for quite a long time, it has had a poor market for print painting trade, with only few collectors dedicated to for this type of painting. In recent years, with print paintings by master artists gaining outstanding performance in the international market, values of original print painting have begun to be recognized in China＇s collection market.  相似文献

明清微雕揉手核桃     

廖文伟 《收藏》2007,(6):138-139

满清末代皇帝溥仪《我的前半生》中提及他曾在紫禁城养心殿后库房中翻看乾隆皇帝的遗物。其中一只精致紫檀木匣装的是这位古希天子的日常用物，溥仪对那对乾隆用过的微雕仙人祝寿揉手核桃记忆扰新。其实故宫博物院珍藏的清宫揉手核桃有十余对，有微雕福寿神佛的，有素面连理并蒂的，或紫檀木匣装放，或丝绦袋网络之，并附有“丹贝勒预备”“恭进”等墨书说明，显然为王公大臣或皇亲国戚贡送给皇室之物。  相似文献

基于背景差分法的虚拟手术损伤区入刀点定位     

廖梦怡  王建玺 《科技通报》2015,(2):197-199

在虚拟手术系统模型中,特别是脑外科手术中,由于背景图像色彩的非规则性和非均匀性,导致对脑部损伤区域的手术入刀切割点的定位不准,影响手术精度和效果。传统方法采用损伤区域差异特征信息提取方法实现入刀点定位,对脑部特征二维灰度图片缺陷边界的定位效果不佳。提出一种基于背景差分法的虚拟手术损伤区入刀点定位算法,构建了虚拟手术的总体结构模型,将背景图像和人体软组织目标图像划分为多个子块,基于直方图选择阈值对差分图像序列进行二值化,得到高斯虚拟人体器官解析模型。设计医学图像分割算法,采用背景差分技术确定手术器械与软组织发生碰撞的激励因子,快速获取碰撞点,实现对虚拟手术入刀点的准确定位。实验结果表明,采用该算法实现虚拟手术系统设计和图像重构,对手术过程中器官损伤区域切割入刀点定位准确,性能优越,视景效果较好,计算时间缩短,精度提高。  相似文献

One-heater flow-through polymerase chain reaction device by heat pipes cooling     

Jyh Jian Chen  Ming Huei Liao  Kun Tze Li  Chia Ming Shen 《Biomicrofluidics》2015,9(1)

This study describes a novel microfluidic reactor capable of flow-through polymerase chain reactions (PCR). For one-heater PCR devices in previous studies, comprehensive simulations and experiments for the chip geometry and the heater arrangement were usually needed before the fabrication of the device. In order to improve the flexibility of the one-heater PCR device, two heat pipes with one fan are used to create the requisite temperature regions in our device. With the integration of one heater onto the chip, the high temperature required for the denaturation stage can be generated at the chip center. By arranging the heat pipes on the opposite sides of the chip, the low temperature needed for the annealing stage is easy to regulate. Numerical calculations and thermal measurements have shown that the temperature distribution in the five-temperature-region PCR chip would be suitable for DNA amplification. In order to ensure temperature uniformity at specific reaction regions, the Re of the sample flow is less than 1. When the microchannel width increases and then decreases gradually between the denaturation and annealing regions, the extension region located in the enlarged part of the channel can be observed numerically and experimentally. From the simulations, the residence time at the extension region with the enlarged channel is 4.25 times longer than that without an enlarged channel at a flow rate of 2 μl/min. The treated surfaces of the flow-through microchannel are characterized using the water contact angle, while the effects of the hydrophilicity of the treated polydimethylsiloxane (PDMS) microchannels on PCR efficiency are determined using gel electrophoresis. By increasing the hydrophilicity of the channel surface after immersing the PDMS substrates into Tween 20 (20%) or BSA (1 mg/ml) solutions, efficient amplifications of DNA segments were proved to occur in our chip device. To our knowledge, our group is the first to introduce heat pipes into the cooling module that has been designed for a PCR device. The unique architecture utilized in this flow-through PCR device is well applied to a low-cost PCR system.  相似文献
