探究不同灌溉量和有机无机肥配施的组合处理对冬小麦生长及水分利用效率的影响,为冬小麦的科学施肥管理提供参考。以关中地区冬小麦‘小偃22’为研究对象,通过田间试验,采用等氮原则对有机肥与无机肥进行不同比例配施(F1,100%无机肥;F2,24%有机肥+76%无机肥;F3,48%有机肥+52%无机肥),结合2个水平的灌溉(充分灌溉W1和亏缺灌溉W2),共设计6个灌溉施肥组合处理(W1F1、W1F2、W1F3、W2F1、W2F2和W2F3)。通过测定冬小麦的生长指标(植株株高和叶面积指数)、0~200 cm土层土壤体积含水率(以20 cm为深度间隔)和小麦的产量及构成要素(干物质量、穗长、有效穗数、千粒质量和籽粒产量),分析灌水量与有机无机肥配施对冬小麦生长及水分利用效率(wuE)的影响。结果表明:(1)充分灌溉(W1)条件下,F2、F3处理株高较F1处理分别提高3.4%~21.2%和0.8%~15.9%,叶面积指数提高5.7%~18.5%和16.8%~47.4%,干物质量提高12.1%~26.1%和21.1%~36.0%,穗长提高12.5%和14.5%,有效穗数提高6.6%和9.3%,千粒质量提高18.3%和24.4%,籽粒产量提高14.8%和28.6%,wuE提高14.6%和27.5%;亏缺灌溉(W2)条件下,与F1处理相比,F2、F3处理株高分别提高8.5%~16.2%和0.5%~10.6%,叶面积指数提高4.9%~20.7%和17.0%~50.0%,干物质量提高7.7%~25.7%和15.0%~34.6%,穗长提高12.3%和18.5%,有效穗数提高7.4%和18.0%,千粒质量提高15.3%和25.1%,籽粒产量提高13.1%和31.8%,wuE提高21.4%和35.2%。在相同灌溉水平下,有机无机肥配施处理可以提高土壤体积含水率。(2)W2F2处理对冬小麦株高增长最有效,灌浆期达最大值,较W1F1处理增长10.4%;W2F3处理对冬小麦叶面积指数、干物质量、穗长、有效穗数、千粒质量影响最大,成熟期较W1F1处理分别提高23.6%、39.0%、20.3%、18.4%和33.1%。(3)W2F3处理对冬小麦籽粒产量和wuE的影响最为显著,W1F1、W1F2、W1F3、W2F1和W2F2处理籽粒产量分别提高了35.5%、18.0%、5.3%、31.8%和16.6%;W1F1、W1F2、W1F3、W2F1和W2F2处理wuE分别提高了52.6%、33.2%、19.7%、35.2%和21.4%。亏缺灌溉与48%有机肥+52%无机肥组合处理的冬小麦籽粒产量和wuE最高,该灌溉施肥管理方案为关中平原及环境相似地区冬小麦的科学施肥管理提供了科学依据。

World Journal of Gastroenterology 2008年第24期14卷 3804-3811页

AIM: To discuss the possible effect of PTEN gene mutations on occurrence and development of gastric cancer. METHODS: Fifty-three gastric cancer specimens were selected to probe PTEN gene mutations in genome of gastric cancer and paracancerous tissues using PCR-SSCP-DNA sequencing method based on microdissection and to observe the protein expression by immunohistochemistry technique. RESULTS: PCR-SSCP-DNA sequencing indicated that 4 kinds of mutation sites were found in 5 of 53 gastric cancer specimens. One kind of mutation was found in exons. AA-TCC mutation was located at 40bp upstream of 3’ lateral exon 7 (115946 AA-TCC). Such mutations led to terminator formation in the 297th codon of the PTEN gene. The other 3 kinds of mutation were found in introns,including a G-C point mutation at 91 bp upstream of 5’ lateral exon 5(90896 G-C),a T-G point mutation at 24 bp upstream of 5’ lateral exon 5 (90963 T-G),and a single base A mutation at 7 bp upstream of 5’ lateral exon 5 (90980 A del). The PTEN protein expression in gastric cancer and paracancerous tissues detected using immunohistochemistry technique indicated that the total positive rate of PTEN protein expression was 66% in gastric cancer tissue,which was significantly lower than that (100%) in paracancerous tissues (P < 0.005). CONCLUSION: PTEN gene mutation and expression may play an important role in the occurrence and development of gastric cancer.

To compare the development of physical crusts in three typical cultivated soils of China, a black soil （Luvic Phaeozem）, a loess soil （Haplic Luvisol）, and a purple soil （Calcaric Regosol） were packed in splash plates with covered and uncovered treatments, and exposed to simulated rainfall. Meshes covered above the surfaces of half of soil samples to simulate the effects of crop residue on crusting. The results indicated a progressive breakdown of aggregates on the soil surface as rainfall continued. The bulk density and shear strength on the surface of the three soil types increased logarithmically as rainfall duration increased. During the first 30 min of simulated rainfall, the purple soil developed a 7-8 mm thick crust and the loess soil developed a 3-4 mm thick crust. The black soil developed a distinguishable, but still unstable, crust after 80 rain of simulated rainfall. Soil organic matter （SOM） content, the mean weight diameter （MWD） of soil aggregates, and soil clay content were negatively correlated with the rate of crust formation, whereas the percentage of aggregate dispersion （PAD）, the exchangeable sodium percentage （ESP）, and the silt and sand contents were positively correlated with crusting. Mechanical breakdown caused by raindrop impact was the primary mechanism of crust formation in the black soil with more stable aggregates （MWD 25.0 mm, PAD 3.1%） and higher SOM content （42.6 g kg-1）. Slaking and mechanical eluviation were the primary mechanisms of crust formation in the purple soil with low clay content （103 g kg-1）, cation exchange capacity （CEC, 228 mmol kg-1）, ESP （0.60%）, and SOM （17.2 g kg-1）. Mechanical breakdown and slaking were the most important in the loess soil with low CEC （80.6 mmol kg-1）, ESP （1.29%）, SOM （9.82 g kg-1）, and high PAD （71.7%） and MWD （4.6 mm）. Simulated residue cover reduced crust formation in black and loess soils, but increased crust formation in purple soil.

作者： shu-Biao wu School of Environmental and Rural Science University of New England

Animal production is a significant protein source for human consumption(Salter and Lopez-Viso, 2021). The production of monogastric animals has grown enormously in recent decades,particularly of poultry and swine(Rauw et al., 2020). Such growth is attributed to the progress in animal nutrition, disease control,and genetic improvement in response to the global demand for meat(Kumar et al., 2023) and, of course, the tireless efforts of scientists working in the area for the past decades. Among them is Professor Mingan Choct, a monogastric animal nutritionist at the University of New England. He has dedicated his entire academic career to the field, significantly contributing to monogastric animal research and industry. To honour his contribution and celebrate his retirement, we organized a special issue in Animal Nutrition with contributions from a group of prominent researchers in monogastric animal nutrition and health. In this special issue, we published reviews and research papers, 8 in total, with a focus on the nutrition and health of monogastric production animals.

译介与内化外来文化是翻译的功用之一。在翻译过程中,一方面由于译者长期浸染于译入语系统文化当中,其翻译活动无疑要受到所属文化传统的影响,其文化立场也必然渗透到他的翻译中。另一方面,由于译者需要考虑服务对象的阅读需求和译作的潜在市场,其翻译活动在很大程度上会受到译入语系统当时流行的创作思想和主流创作形式的影响。十七十八世纪至五四前后这一段特定的历史时期,译入语文化对翻译活动的内化与规约表现在:为了满足中国读者的心理需求,将外国人名、地名、称谓等专有名词中国化;为了迎合国人的审美情趣,因袭传统写作模式和风格,小说常采用仿章回体的翻译体例,诗歌多采用中国古典诗词形式;为了帮助读者欣赏作品,大幅增、删或改造原文的现象十分普遍。这种内化现象表面上是对原著的篡改和"变形",其实说到底还是翻译主体在试图消解中西两种文化间的差距,有其自身存在的合理性。

我国翻译史长达2000年之久,但从文字记载来看,男性译者一直占据翻译史的主导地位。众多的女性译者被淹没在历史的长河里,形成了一个被遗忘的群体。借鉴西方女性主义翻译史研究的经验,同时考虑到中国的国情和史情,我们不仅要认识到进行女性翻译史研究的必要性和紧迫性,而且更要估计到这项工程的艰巨性和复杂性。我国的女性翻译史研究要寻找科学的理论支撑、采用适当的撰写体例、使用合理的研究方法、重视史料的收集和拓展。
