我国农作区资源节约农作压力空间分布研究

资源节约型农作制是进行农业资源节约、高效利用的农作制度, 将成为我国农业生产中突破资源短缺这一发展瓶颈的有效手段。为明确我国主要农作区的资源特点和节约压力, 选择农业水、耕地、化肥3 种资源为主要研究对象, 根据目前各农作区3 种资源的数量、消耗率、粮食产量水平等指标, 初步计算了各区节水压力、节地压力与节肥压力, 并据此初步推导出各区资源节约农作制的综合压力指数, 研究了资源节约农作制压力的空间分布。结果显示: 我国绝大多数农作区资源节约型农作制压力处于中度以下, 东部各农作区大于西部各农作区, 南方各农作区大于北方各农作区; 节水重点区主要是北方的东北区、黄淮海区、西北区和北部低中高原区, 节地重点区主要是东南部的长江中下游地区、江南地区和华南区, 节肥重点区主要是四川盆地、华南区和江南区。     

Pressure correction to the long-term measurement of carbon dioxide flux

Fluctuations in atmospheric CO₂ density can arise from static pressure fluctuations but their effect on the long-term eddy covariance (EC) CO₂ flux measurement is poorly known. In this paper, we report the results of a 1-year direct measurement of the static pressure fluctuations and the velocity-pressure covariance over a mixed forest in Northeast China. The results show that the pressure-vertical velocity covariance was primarily controlled by friction velocity and air stability. Without the pressure correction, the open-path EC measurement of the nighttime ecosystem respiration was biased low and that of the daytime photosynthetic CO₂ uptake was biased high. Over the 1-year measurement period, the cumulative pressure correction was 40 gCm⁻², which was about 20% of the annual net ecosystem production of this forest. Using the friction velocity data found in the literature, we estimated the magnitudes of the pressure correction for the major ecosystem types in the long-term global EC network (FluxNet).

Effect of heat treatment and germination on alpha amylase inhibitor activity in chick peas (Cicer arietinum L.)

Chick pea seeds of twenty eight varieties were analysed for alpha amylase inhibitor activity (AIA) using salivary amylase. The effects of heat treatment and germination on the activity of the antinutritional factor was investigated. Heat treatment and germination decreased the activity of amylase inhibitor. Chick pea meal was also subjected to UV irradiation and pressure cooking. These treatments decreased alpha amylase inhibitor activity. The amylase inhibitor activity decreased as the days of germination increased and negligible inhibitor activity was observed on the 6th day of germination.

Dynamic modeling and control of pressure dyeing machine’s running roller system

Key factor determining production quality is the deformation control between running rollers of pressure dyeing machine during the operation. Currently the industrial communities try to alleviate the defects by taking experiments. This study aims to approve theoretical practicality of providing controller and its parameters suitable to abolish vibration displacement in operating pressure dyeing machine in order to improve pressure dyeing quality and lengthen machine’s life. Firstly, the dynamic equation of the pressure dyeing machine’s running roller is derived and its corresponding open-loop transfer function is obtained from modal summation method. Then, the root locus method is used to design a controller which is realizable in the industrial communities. Simulation indicates that the designed controller not only can eliminate vibration response generated during pressure dyeing process and reducing greatly the previous process defects by making the two running rollers smoothly contact with each other. The solution is a high efficient way to ameliorate pressure dyeing process with low cost and easy access.
