利用珠江三角洲5个城市气象观测站(广州、深圳、台山、惠州、高要)的长期能见度观测资料,采用累积百分率、Ridit分析法和烟幕/霾日频率3种统计分析方法,分析了1954—2004年珠江三角洲能见度变化趋势,初步探讨了珠江三角洲大气环境的变化特征及其可能原因。结果表明:近50年来,珠江三角洲城市能见度呈显著下降趋势。能见度的下降起始于20世纪70年代初,并在经济高速发展的80—90年代初进一步恶化,90年代中期之后虽然能见度变化趋于平缓,但能见度下降的趋势仍未从根本上改变。珠江三角洲能见度与当地的人口增加和经济发展程度有密切的关系,同时污染物的区域输送对西部下风向城市能见度也有很大影响。珠江三角洲能见度未得到有效改善的主要原因,很可能是由于细粒子污染,尤其是二次粒子前体物如SO2和NOX等的排放未得到有效控制。

大气气溶胶的气候效应和环境效应研究是当今国际科技界的热门话题。近年来珠江三角洲地区的气溶胶污染日趋严重,一年四季长期稳定存在气溶胶云,重污染区偏于珠江口以西的珠江三角洲西侧。灰霾天气主要出现在10月至次年4月。大气灰霾导致能见度恶化。自20世纪80年代初开始,该地区的能见度急剧恶化,灰霾天气显著增加,其中有3次大的波动,分别代表与珠江三角洲经济发展相伴随的气溶胶污染、硫酸盐加气溶胶污染、光化学过程的细粒子加硫酸盐加气溶胶的复合污染时期。雾和轻雾造成的低能见度的长期变化趋势,没有由于人类活动影响或经济发展影响带来的趋势性变化,其波动主要反映了气候波动固有的年际和年代际变化。珠江三角洲能见度的恶化主要与细粒子关系比较大,PM10有一半月均值超过国家二级标准的日均值浓度限值(150μg/m3),而PM2.5月均值全部超过美国国家标准的日均值浓度限值(65μg/m3),尤其是10月至次年1月的月均值浓度几乎超过标准限值的1倍,细粒子浓度甚高。另外PM2.5占PM10的比重非常高(58%—77%),尤其是旱季比雨季更高。与15a前的资料相比较,细粒子在气溶胶中的比重有明显增加,因而在目前珠江三角洲的气溶胶污染中,主要是细粒子的污染。

[Objectives] This study was conducted to improve the nutritional value of soybean milk, enrich the variety and taste of soybean milk, and find healthy food that is more conducive to people s nutritional needs. [Methods] Whole soybean milk was prepared by grinding with a grinding wheel at a low concentration (low-concentration grinding) and a stainless steel mill at a high concentration (high-concentration grinding). The sensory, physical and chemical characteristics and anti-nutritional factors of whole soybean milk produced by different grinding methods were studied. [Results] Compared with low-concentration grinding, the protein content in soybean milk prepared by high-concentration grinding increased by 24%, and the dietary fiber content increased by 74.7%. Before and after high-pressure homogenization, the particle size D(4, 3) of soybean milk prepared by low-concentration grinding was 212.1 and 93.59 μm, respectively, and the particle size D(4, 3) of soybean milk prepared by high-concentration grinding was 134.0 and 64.64 μm, respectively. The trypsin inhibitor activity and phytic acid content of soybean milk prepared by high-concentration grinding were significantly lower than those of soybean milk prepared by low-concentration grinding. [Conclusions] This study improves the diet structure of the broad masses of people, strengthens people s physique, and provides a new idea for the implementation and development of China s "Soybean Action Programme".

传统的切削过程功率获取需要基于复杂的切削功率模型且很少考虑刀具磨损的影响,针对此设计了一种基于变分模态分解(VMD)、麻雀搜索算法(SSA)、长短时记忆(LSTM)神经网络的考虑刀具磨损的数控铣床切削功率预测模型,该模型无需解构数控铣床运行过程的能耗机理,基于一次性的历史实验数据即可实现数控铣床切削过程功率的高精度预测。首先,采用人工智能机器视觉技术对刀具磨损图片进行分析处理,获取刀具磨损图像的数字化特征,从而得到刀具最大磨损量;然后,建立基于VMD-SSA-LSTM考虑刀具磨损的数控铣床切削功率预测模型,利用VMD对数控铣床运行数据进行分解,采用SSA算法对LSTM神经网络超参数进行寻优,并将分解出的铣床运行数据分量输入到LSTM神经网络中,接着将每个分量的预测值相加,得到切削功率预测值;最后以面铣加工为例,将所提出的预测模型与BP神经网络、LSTM神经网络和传统模型进行对比分析,验证了所提模型的有效性和优越性。
