The laser light scattering technique for non-invasivein situ simultaneous measurements on elastic constants and viscosity coefficients of nematic liquid crystals is introduced. By measuring the autocorrelation function of the scattered light from nematic liquid crystals at different scattering angles, the splay and twist elastic constantsK 11 andK 22 are obtained from the amplitudes of the autocorrelation function, and the viscosity coefficients ofη Splay andη Twist are determined using the viscoelastic ratiosK 11/η Splay andK 22 η Twist from the telaxation parameters of the two modes.

为解决三维激光检测中被测物体底面点云无法被高效获取的问题,本文提出了基于直角三棱镜折射原理的补充视角三维点云扫描获取方法。该方法使用直角三棱镜将底面图像折射到侧面,弥补了三维检测的底面检测视角缺失的问题,补充了底面检测视角。本文以密封圈作为缺陷检测对象,采用结构光三维相机采集三维点云。与直接扫描法相比,本方法可以一次性实时、快速地寻找出密封圈完整的表面缺陷,尤其使底面缺陷检测变得更容易,且无需设置特殊的夹取装置或复杂的机械臂等机械结构,仅需增加一块直角三棱镜。实验证实,直角三棱镜补充视角的点云扫描方法能够达到成像要求,对常见的密封圈断裂缺陷与塌陷缺陷均可很好的检出,检测准确率可达到100,满足密封密封圈缺陷检测的需求。

Chitosan/poly(ε-caprolactone) (PCL) blend films in different mass ratios were prepared using the chitosan/PCL mixture solutions in 80 vol.-% acetic acid by spin coating. Their surface micromorphologies were assessed by atomic force microscopy (AFM). It was found that the micromorphology of chitosan/PCL blend films was in large extent related to the mass ratio of chitosan. 25 wt% chitosan/PCL blend film presented microphase separation. The protein adsorption of bovine serum albumin (BSA) onto chitosan/PCL blend films was investigated by using quartz crystal microbalance with dissipation monitoring (QCM-D) in real time. The results suggested that the amount of adsorbed BSA on the chitosan/PCL blend films decreased with the addition of chitosan, but the structure and viscoelastic properties of the adsorbed BSA layers were greatly affected by the surface micromorphology of chitosan/PCL blend films. BSA absorbed on the 25 wt% chitosan/PCL blend film with microphase separa- tion showed larger adsorption reversibility, and preferred to form a loose, dissipative layer in comparison with those on other chitosan/PCL blend films without microphase separation.

点云多视拼接在制造业领域中自动化测量方面具有重要作用。目前，点云多视拼接的技术在拼接效率和拼接精度上存在不足。提出一种新的利用旋转台运动的点云多视拼接方法。使用特征简单的圆环形校准件，校准过程更加灵活，适用性更强。在ICP配准算法运行前进行点云摆正与旋转变换，提高了算法的运行效率与精度。首先利用对旋转台旋转角度的精确控制，采集校准件全部视角的点云数据，进行分析与处理后，实现旋转台在点云空间坐标系里的位置校准。之后利用旋转台运动完成点云多视拼接，使用ICP配准算法进一步提高拼接精度。试验表明，该方法拼接时间短，效果好。

Heparin was covalently immobilized onto polyurethane surface via a PEG spacer by a microwave-assisted approach to improve blood compatibility. Firstly, amino-terminated poly（ethylene glycol）（APEG） was rapidly grafted onto PU surface within 20 rain by a two-step method involving microwave-assisted MDI-functionalization and subsequent microwave-assisted APEG coupling. Then, heparin was eovalently immobilized through an amide linkage by the direct coupling of the carboxylic acid of heparin with the amino group of APEG on PU surface using carbodiimide coupling reaction. The surface structure and properties were characterized by X-ray photoelectron spectroscopy （XPS）, atomic force microscopy （AFM） and water contact angle measurements. The results revealed that hepadn-immobilized PU surface had slightly increased roughness and significantly improved hydrophilicity in comparison to the original PU surface. The anticoagulant activity of films was evaluated by whole blood clotting time （CT） and prothrombin time （PT）. Complement activation was assessed by detecting complement fragment 3a concentrations of serum exposed to the films. The results revealed that the microwave-assisted heparin-immobilized PU films had excellent antithrombogenicity and suppressed complement activation, indicating improved blood compatibility.

A novel method for measuring the min- ute fluctuation of cell membrane is developed by modifying the super-resolution theory, increasing dimension in Fourier space, enhancing brightness gradient and utilizing maximum adaptive weighted averaging filter (MAWA) in obstructing noise. The application of the method in studying aspergillus fla- vus cell (AFC) and red blood cell and the new find- ings from the study show that it is a useful tool.
