首先研究评估三种预冷技术对当地生长的绿芦笋在1.5℃普通大气(RA)下贮藏21天的效果。其次研究评估两种不同相对湿度(RA)和三种不同气体组成,在1.5℃自发气调贮藏(MA)21天的绿芦笋品质。在实验容器上装有硅窗以保持 MA 条件。贮藏前预冷芦笋,可减少损耗20%以上。然而,这三种预冷技术之间差异并不显著。28天后,MA 贮藏的芦笋与相对湿度为80%的 RA 贮藏(质量损耗60%)和相对湿度为95%的 RA 贮藏(质量损耗41%) 相比,色泽较好,外观新鲜、质地较硬,质量损耗较低(<12%)。尽管硅窗能适当控制CO_2浓度,但为了防止缺氧呼吸,必须定期注入氧气。

Microwave Drying of Flax Fibre at Controlled Temperatures

Journal of Agricultural Science and Technology(B) 2011年第8期1卷 1103-1115页

Drying is essential for the production of fibre after retting process. Flax fibre was subjected to microwave drying at controlled temperatures to study the change in drying rate and qualities. The rate of drying was then compared with conventional hot air drying. The product temperature was maintained at 40 °C, 60 °C or 80 °C for both microwave and hot air drying. The initial moisture content of flax fibre was about 60% (wet basis). The microwave drying was conducted in a microwave apparatus which recorded mass, product temperature, incident microwave power, reflected microwave power and inlet/outlet air temperature. The final moisture content was set to 9% (wet basis). Microwave-convective drying ensured about 30% to 70% reduction of drying time for drying flax fibre as compared to hot air drying. Curve fitting with different mathematical models were carried out. While a significant difference in colorimeter-assessed colour existed between microwave-convective dried flax fibre and hot air dried flax fibre. The tensile strength of flax fibre, measured with an Instron apparatus, increased with an increase in the processing temperature of both processes. Hot air dried flax fibre showed the greatest tensile strength and modulus of elasticity at processing temperatures of 60 °C and 80 °C.

亚麻原茎收获后需要经过水沤或雨露脱胶以制取纤维,但这2种方法耗时长、有污染,本文利用射频介电加热进行亚麻原茎脱胶。为研究射频脱胶方法,明确脱胶介质与功率、温度和处理时长对亚麻脱胶质量的影响方式,进行了3组对比试验,脱胶质量则通过脱胶效果和纤维力学性能两类指标进行综合评价。通过组内与组间麻茎失重率的分析得出,无水射频较有水射频脱胶会增加脱胶效果;并且不管何种脱胶介质,增加射频功率、温度和处理时长都会改善脱胶效果。通过亚麻纤维力学性能的比较分析得出,相比于原麻纤维,无水射频频脱胶后纤维的拉伸性能显著降低(P<0.05),而有水射频脱胶时增加温度和处理时长则有使拉伸强度增大的趋势。综合考量,亚麻原茎短时水沤后采用有水射频脱胶能够获得较优的脱胶质量,可以成为一种亚麻原茎绿色、高效的增值化处理方法。

＜正＞ Bajra (Pearl millet Pennesetum glaucum （L.） has been grown in India and Africa since prehistoric times. It is well adapted to arid conditions and can be grown in areas where other common cereal crops such as wheat or maize cannot be cultivated. It is the basic staple for households involved in agriculture and among economically poorer sections. The millet is consumed in the form of fermented or non-fermented breads, porridges, boiled or steamed foods. Bajra is considered nutritionally superior to rice and wheat. Lately, the demand for

世界核心医学期刊文摘（妇产科学分册） 2005年第3期1卷 16-17页

This study was undertaken to determine the predictive accuracy for preterm birth of transvaginal ultrasound (TVU) of the cervix in women with a prior cone biopsy. Pregnant patients with a history of cervical cone biopsy by cold knife, loop electrosurgical excision procedure (LEEP), or laser were monitored prospectively with TVU of the cervix between 16 and 24 weeks. The predictive value of TVU was evaluated by using less than 25 mm cervical length as criteria for the definition of a short cervix. The primary outcome was spontaneous preterm birth less than 35 weeks. Of 109 women with prior cone biopsy identified, 55 had LEEP, 45 cold knife, and 9 laser cone biopsies. Thirty (28% ) had a short cervix, with 9 (30% ) having spontaneous preterm birth less than 35 weeks. Seventy nine (72% ) did not have a short cervix, with 5 (6% ) having spontaneous preterm birth less than 35 weeks. The sensitivity, specificity, and positive and negative predictive values for spontaneous preterm birth were 64% , 78% , 30% , and 94% , respectively (relative risk 4.7, 95% CI 1.6- 15.3). TVU of the cervix is predictive of preterm birth in women with prior cone biopsy.
