在某些电子测量测试应用场合里,要求对模拟信号进行相参数据采集,采集系统使用的采样时钟、数字下变频时钟和触发信号均由某个高稳时钟源通过分频和倍频得到,这样可以保证采集到的信号严格保持原始信号的相参性。目前广泛应用的美国国家仪器(National Instrument,NI)高速数字采集系统没有采样时钟和数字下变频时钟采用同一个外时钟源的模块,需要在现有模块的基础上进行二次开发。针对这个需求,采用目前市场上常见的NI模块,构建了采用外时钟的多通道高速相参同步数据采集与存储系统。对系统时钟变换、数字正交下变频和高速流盘等系统设计的几个关键技术,进行了详细分析并给出设计方案。

Multistation machining process is widely applied in contemporary manufacturing environment. Modeling of variation propagation in multistation machining process is one of the most important research scenarios. Due to the existence of multiple variation streams, it is challenging to model and analyze variation propagation in a multi-station system. Current approaches to error modeling for multistation machining process are not explicit enough for error control and ensuring final product quality. In this paper, a mathematic model to depict the part dimensional variation of the complex multistation manufacturing process is formulated. A linear state space dimensional error propagation equation is established through kinematics analysis of the influence of locating parameter variations and locating datum variations on dimensional errors, so the dimensional error accumulation and transformation within the multistation process are quantitatively described. A systematic procedure to build the model is presented, which enhances the way to determine the variation sources in complex machining systems. A simple two-dimensional example is used to illustrate the proposed procedures. Finally, an industrial case of multistation machining part in a manufacturing shop is given to testify the validation and practicability of the method. The proposed analytical model is essential to quality control and improvement for multistation systems in machining quality forecasting and design optimization.

普拍枋的横纹受压变形积累等残损现象是应县木塔结构发生竖向沉降和损坏的重要原因,严重影响木塔的安全性能。为研究应县木塔普拍枋的取材用材信息与残损现状,通过现场勘察记录各层普拍枋用材的年轮数、髓心位置与受压处的压缩情况,并采用无损检测技术获得木材年轮宽窄面与木材大小头摆放方式,同时对端面图像进行处理以计算端面裂隙率与缺损率。研究结果表明,应县木塔普拍枋用材为树龄大于100年的华北落叶松(Larix principis-rupprechtii Mayr.),且尽可能保证了木材两端髓心处于中心位置,同时木材的年轮宽窄面与大小头摆放存在一定规律;木材横纹受压残损是普拍枋的主要残损形式,其中压缩程度大于20%的木构件在各明层内槽普拍枋中占50%,同时随着木塔的使用普拍枋压缩程度仍在增加;木材局部受压是木构件端面开裂残损的重要原因,其中木构件局部受压压缩程度与端头开裂裂隙率呈高度线性相关。

On 15 September 2020,the Arctic sea-ice extent(SIE)reached its annual minimum,which,based on data from the National Snow and Ice Data Center(NSIDC,2020a),was about 3.74 million km^(2)(1.44 million square miles).This value was about 40%less than the climate average(~6.27 million km^(2))during 1980–*** was second only to the record low(3.34 million km^(2))set on 16 September 2012,but significantly smaller than the previous second-lowest(4.145 million km^(2),set on 7 September 2016)and third-lowest(4.147 million km^(2),set on 14 September 2007)values,making 2020 the second-lowest SIE year of the satellite era(42 years of data).

While Arctic sea ice has been decreasing in recent decades that is largely due to anthropogenic forcing,the extent of Antarctic sea ice showed a positive trend during 1979–2015, followed by an abrupt decrease. The shortness of the satellite record limits our ability to quantify the possible contribution of anthropogenic forcing and internal variability to the observed Antarctic sea ice variability. In this study,ice core and fast ice records with annual resolution from six sites are used to reconstruct the annualresolved northernmost latitude of sea ice edge(NLSIE) for different sectors of the Southern Ocean, including the Weddell Sea(WS), Bellingshausen Sea(BS), Amundsen Sea(AS), Ross Sea(RS), and the Indian and western Pacific Ocean(Ind WPac). The linear trends of the NLSIE are analyzed for each sector for the past100–200 years and found to be à0.08°, à0.17°, +0.07°, +0.02°, and à0.03° per decade(!95% confidence level) for the WS, BS, AS, RS, and Ind WPac, respectively. For the entire Antarctic, our composite NLSIE shows a decreasing trend(à0.03° per decade, 99% confidence level) during the 20 th century, with a rapid decline in the mid-1950 s. It was not until the early 1980 s that the observed increasing trend occurred. A comparison with major climate indices shows that the long-term linear trends in all five sectors are largely dominated by the changes in the Southern Annular Mode(SAM). The multi-decadal variability in WS,BS, and AS is dominated by the Interdecadal Pacific Oscillation, whereas that in the Ind WPac and RS is dominated by the SAM.
