楔块斜入射检测工艺下,楔块会进一步降低全聚焦成像的缺陷检测能力。尤其是在检测大深度缺陷和粗晶材料时,全聚焦图像会因为缺陷回波幅值下降,导致缺陷图像的信噪比较低。为了提高入射能量,提出了应用于斜楔块的子孔径虚拟源全聚焦成像技术。研究结果表明:该技术通过延时控制子孔径阵元激励形成虚拟源发射,显著增加了射入到被检构件中的声能。在横向L值为20∼40 mm探头移动区间内,17∼38 mm深度范围内Φ3边钻孔幅值较黄铜全聚焦图像提高4.58∼7.12 dB;当钢制试块为被检对象时,在横向L值为30∼40 mm探头移动区间内,40∼65 mm深度范围内Φ1边钻孔幅值较全聚焦图像提高0.63∼2.35 dB。因此在该技术应用于楔块斜入射检测工艺下的粗晶材料检测,具有较好的检测效果。

Owing to its unique superiority in improving quality of life and prolonging survival time among advanced lung cancer patients, Chinese medicine（CM） has, in recent years, received increased attentions worldwide. We utilized a bibliometric statistical method based on MEDLINE/Go Pub Med to conduct a comprehensive analysis of the current application status of CM in lung cancer, by including annual and accumulated publications, origin distribution of countries and journals, and keywords with a higher frequency score. Then the relevant clinical trials and mechanistic studies were systematically summarized within the field according to research types. We have raised potential problems and provided potentially useful reference information that could guide similar studies in the future. The basic experimental results are highly consistent with clinical trials, leading us to conclude that CM can offer better overall therapeutic benefits when used in combination with routine Western medicine for patients with advanced lung cancer.

The electrochemical behaviors of n-type silicon wafers pH value and solid content of the slurry on the corrosion of silicon in silica-based slurry were investigated, and the influences of the wafers were studied by using electrochemical DC polarization and AC impedance techniques. The results revealed that these factors affected the corrosion behaviors of silicon wafers to different degrees and had their suitable parameters that made the maximum corrosion rate of the wafers. The corrosion potential of （100） sttrface was lower than that of（111）, whereas the current density of （100） was much higher than that of（111）.

The spatial structure of a Bose-Einstein condensate （BEC） loaded into an optical lattice potential is investigated and the spatially chaotic distributions of the condensates are revealed. A method of chaos control with linear feedback is presented in this paper. By using the method, we propose a scheme of controlling chaotic behavior in a BEC with atomic mirrors. The results of the computer simulation show that controlling the chaos into the stable states could be realized by adjusting the coefficient of feedback only if the maximum Lyapunov exponent of the system is negative.

Amphiphilic copolymer of 5-benzyloxytrimethylene carbonate （BTMC） with poly （vinyl pyrrolidone）（PVP） was successfully synthesized using immobilized porcine pancreas lipase （IPPL） or SnOct2 as catalyst. Hydroxyl terminated PVP, synthesized with 2-mercaptoethanol as a chain transfer reagent, was employed as a rnacroinitiator. The resulting copolymers were characterized by GPC, ^1H NMR and IR. Increasing the BTMC/PVP-OH feed ratio （[B]/[P]） resulted in the increase of Mn of corresponding copolymers and the decrease of Mw/Mn. Immobilized enzyme has comparable catalytic activity to SnOct2 for the copolymerization.
