The results of Which experiment, herein reported was carried out at a newly established black tea factory in Sao-Shing, Chckiang, during 1957. The methods of biochemical examination are based on those used by tea factories in U. S. S. R. Which including such analysls as water contents of the withering leaves, percentage of buoken tissue after rolling, changing of soluble tannin during fermentation and water contents of the first and the second drying. According to the results of biochemical examination, standards for the biochemical control of processing Ping-Suey Black-tea are susgested as in the following. 1. The average water contents, in green leaves of the spring, summer, and autumn flushes are 76.2±2.25; 74.54±1.41, and 74.16±0.86, respectively. The average surface water on rainy days is 9.9±4.0, such green leaves also have a relatively higher water content than leaves collected on non-rainy days. It is suggested that the weight of the extra water content should be deducted with the surface water when collecting leaves on rainy days. 2. The average water contents of the spring, summer and autnm flushes are reduced to 65.18±2.98, 63:9±2.73 and 63.9±3.0 respectively after withering. But better quality teas are between 58 and 60%. 3. After the last rolling the percentage of broken tissue of the No.3 dhool are: 90.0±5.6, 84.4±8.4 and 84.4±8.4; but the best is between 81% and 85%. 4. Soluble tannin contents are decreasing in the processing. The average percentages are: for green leaves 25.6±3.6; for withered leaves 22.1±2.6; both before and after fermentation, No. 1 dholl 21.3—16.3, No.3 dholl 19.1—12.8; dry tea, 12.6 (No. 1 dholl); 11.6 (No.2); 10.2(No.3). According.to statistical analysis, suggested figures for soluble tannin during fermentation for different ranges are tablated. 5. Water conents should be reduced to 18—24% after the first drying and 4—6% after the second drying.

1957年在越紅茶区的一个新建的机械化茶厂——浙江紹兴紅茶初制厂进行了紅茶初制工艺过程的生化管理試驗。試驗采用苏联茶厂的生化管理方法,对茶厂的生产过程作了生化檢驗,这就是萎凋检驗水分,揉捻檢驗細胞破碎率,发酵檢驗可溶性單宁的递減,干燥檢驗殘余水分。作者根据生化檢驗结果,經过統計分析,提出了越紅初制生化管理的指标如下: 1.生叶水分,春夏秋茶各为:76.20±2.25;74.54±1.41;74.16±0.86。雨水叶表面水分为9.9±4.0。 2.萎凋叶水分,春、夏、秋茶各为:65.2±3.0;63.9±2.7;63.9±3.0。良好萎凋的水分指标应该是58—62%。 3.揉捻叶细胞破碎率各茶季平均:1次1号茶61—62%;2次1号茶79—93%;3次1号茶90—92%(夏秋茶);品質最好的在86%以上。最后一次揉捻的3号茶的细胞破碎率平均在84—90%,品質较好的是81—85%。由上可知1次1号茶普遍细胞破碎率低,反映揉捻不足,可见1次1号茶单独发酵的技术规程不适于越红初制,应改为并入2次重揉,1957年生产实践证明这样的改变,结果良好。 4.初制工艺过程,可溶性单宁是有规律的递减,以夏茶为例,...

It is shown by the principal component analysis of the annual andseasonal mean temperature series of 42 stations in China during theperiod of 1881--1981 that the whole country can be divided into fiveareas according to the spatial distribution of the variance contribu-tion of the principal components to the temperature series in eachstation.

It is shown by the principal component analysis of the annual andseasonal mean temperature series of 42 stations in China during theperiod of 1881--1981 that the whole country can be divided into fiveareas according to the spatial distribution of the variance contribu-tion of the principal components to the temperature series in eachstation. During the past hundred years the trend of the annual andseasonal mean temperature in the most part of China was very simi-lar to that of the mean temperature in the northern hemisphere. It isalso shown by the analysis of variance spectrum of the first threeprincipal components that the significant statistical period was variedfor different components, but most of them were concentrated in thethree wave bounds, i.e.. wave bounds of 18.4--28.9, 2.9--3.0 and 2.2--2.3 years and the periodic component of 18.4--28.9 years coincidedwith the phase of the double 11-year sunspot cycle.

对我国42个测站1881—1981年的年、季平均气温进行主成分分析的结果表明,按照气温年际变化的不同特征,全国可划分成五个区域,每个区域中,与大尺度气温距平分布年际变化相关联的单站气温年际变化的主要特征,分别可用一至二个主成分的线性组合表征。近百年来,除东北和新疆北部地区以外的我国大部分地区,气温长期变化趋势的主要特征都与北半球平均气温的趋势相一致,即从本世纪初到1945年前后和70年代以来,是两个明显的增暖时段,它们中间是一个降温时段。东北和新疆北部地区,气温长期趋势比较平缓,它们的最北部分,甚至可以观测到与北半球平均气温趋势相反的长期变化趋势。对年、季平均气温序列主成分进行方差谱分析的结果表明,尽管各主成分的显著周期各不相同,但这些显著周期却相对集中地出现在18.4—28.9年、2.9—3.0年和2.2—2.3年三个波段。在这三个波段内,显著周期出现频数或方差谱的平均值达到了信度α=0.01的显著标准,其中18.4—28.9年波段中的周期分量与太阳黑子11年周期双周的位相配合相当紧密。

Long-term Change of air temperature in the Yangtze Delta was inves-tigated by using monthly mean air temperature data of Shanghai during the years from 1873 to 1985. The results indicate that the long-term Change curves of air temperature in this area appear as Wave-like form in shape. Its minimum value of yearly or seasonly mean air temperature occurring in the last thirty years was not lower than that occurring in the previous eighty years, and the maximum value occurring in the last period was equivalent...

Its minimum value of yearly or seasonly mean air temperature occurring in the last thirty years was not lower than that occurring in the previous eighty years, and the maximum value occurring in the last period was equivalent to that before.

本文用1873—1985年上海平均气温资料研究长江三角洲气温长期变化的规律.结果表明:本地区气温长期变化曲线呈波动形式.近三十余年中出现的年,季平均气温最低值未曾低于前八十年所曾出现过的最低值,而最高值却有与以往出现过的最高值相当的.取一百十三年平均气温作基准,则由累积距平曲线可见近五十年上海气温以正距平即暖年占优势.文中还讨论了气温年波长期变化的特征.
