波轮式洗衣机的洗涤机理探讨

波轮式洗衣机又称涡漩式洗衣机,是一种依靠旋转波轮产生的洗涤液涡流,带动织物在涡流中运动,并在洗涤剂的物理和化学作用下及水流的机械作用下,使污垢不断脱离衣物,达到洗净效果的洗衣机,它最初源出于日本.

家庭洗涤中织物运动测量方法探讨

家庭洗涤中织物的运动过程与洗后性能直接相关。针对洗涤运动特点,围绕织物家庭洗涤时的受力分析、动作分解、速度监测和轨迹跟踪四个方面,得出织物温态性能测量技术、高速摄像技术、传感器技术和电子示踪技术在洗涤运动测量中的研究应用;同时指出未来可以从测量设备的适用性和稳定性、织物含水率的可控性、动作分解原则的可靠性等技术难点深入探索,为实现高效、环保、智能化的家庭洗涤提供更全面的理论依据和更有效的技术支持。

压缩气泡式洗衣机

本发明专利公开了一种压缩气泡式洗涤机理及其压缩气泡式洗衣机，它将使使用表面冲刷洗涤机理的渡轮式和滚筒式洗衣机成为历史。压缩气泡式洗涤机理的提出，是在充分研究手工揉搓和棒槌捶洗衣物的基础上，抽取它的主要机量．摈弃它揉搓动作复杂不易机械模仿、洗涤功率小、开放式压缩气泡利用率低等缺点而完成的。

Detection of carcinoembryonic antigen mRNA in peritoneal washes from gastric cancer patients and its clinical significance

AIM： To establish a more sensitive method for detection of free cancer cells in peritoneal washes from gastric cancer patients during surgery and to evaluate its clinical significance. METHODS： The carcinoembryonic antigen （CEA） mRNA levels in peritoneal washes from 65 cases of gastric cancer were detected by real-time RT-PCR. Peritoneal lavage cytology （PLC） was applied simultaneously to detection of free cancer cells. Negative controls included peritoneal washes from 5 cases of benign gastric disease and blood samples from 5 adult healthy volunteers. RESULTS： There was no CEA mRNA in peritoneal washes from benign gastric disease patients and in blood of adult healthy volunteers. The positive percentage of free cancer cells detected by real-time RT-PCR was 47.7% and only 22.3% by PLC. The positive rate of CEA mRNA was significantly related with serosa invasion between peritoneal metastasis and stage of gastric cancer. CONCLUSION： Real-time RT-PCR is a sensitive and rapid method for the detection of free cancer cells in peritoneal washes. The presence of free cancer cells in peritoneal washes is related to the Pathologic stage of gastric cancer.
