两个不同彩色棉纤维品质性状形成特点及生长调节剂调节作用

选择天然棕色棉品种湘彩棉2号和绿色棉品种皖棉39,研究其纤维品质性状形成特点及激素调节作用。结果表明与常规白色陆地棉苏棉9号(对照)相比,2个彩色棉品种的纤维长度均较低,尤其皖棉39显著低于对照,主要是花后10~30 d伸长速率明显下降。两个不同彩色棉品种的纤维比强度、马克隆值和成熟度值均显著低于对照,且主要与各个品质指标形成关键期的增长率较慢有关。两个彩色棉品种10 DPA (days post anthesis)和20 DPA纤维中IAA含量,30 DPA和40 DPA ABA含量均显著低于各自对照。应用20 mg L^-1 GA₃处理棉铃后,湘彩棉2号、皖棉39 20 DPA纤维中IAA含量分别比各自对照提高51.07%、64.33%;吐絮时纤维长度分别比各自对照增加8.13%、13.96%;应用20 mg L^-1 ABA处理棉铃,40 DPA纤维中ABA含量分别比各自对照提高38.96%、24.40%,纤维比强度、马克隆值和成熟度也显著增加,其中又以皖棉39增加幅度较大。说明天然彩色棉纤维内源激素IAA和ABA含量不足影响纤维品质性状的形成,而通过植物生长调节剂应用可调节内源激素含量,改善纤维品质,且调节效应因植物生长调节剂和品种不同而异。     

Reducing the Heating and Cooling Energy Consumption of Buildings

Abstract:This research aims at proposing measures to enhance the energy efficiency of buildings in the city of Guiyang. A computer simulation study was conducted on the basis of a building model using the DeST software package. The indoor temperature and year round heating and cooling loads were simulated. From analysis of the simulation results and taking into account the climate of Guiyang, three measures for energy efficient buildings in Guiyang are proposed. 1) Heating is a greater priority than cooling in comfortable air conditioning system design; 2) Natural ventilation should be given priority in cooling design and adjustment during seasonal transition is important to reducing energy consumption in building cooling; 3) Insulating the building envelope and lowering the glazing ratio of walls are critical for reducing energy consumption in heating buildings. Our conclusions will be useful for guiding energy efficient building design not only in Guiyang but also in mild climatic areas of P. R. China.     

Building Damage in Mianyang City Caused by the May 12, 2008 Earthquake in Wenchuan, Sichuan Province, P. R. China

Summarizing building damage in all previous large earthquakes is an important approach to promote the development of structural seismic design. We conducted a statistical analysis of the earthquake damage to various buildings in Mianyang city, Sichuan province, P. R. China. This analysis was based on the emergency assessment and investigation of building damage in Mianyang city caused by the large earthquake that occurred on May 12, 2008 in Wenchuan. We also summarize the damage characteristics of different buildings and the lessons learned. We present the following findings and suggestions for structural seismic design:(1)Buildings in Mianyang designed according to current seismic code withstood the rare earthquake.(2)Different structural systems have obviously varied seismic behaviors. (3)Old buildings always have been the weak links in earthquakes, and should be evaluated and strengthened selectively after an earthquake.(4)Studies of anti cracking measures for masonry walls should be conducted. (5)Effective measures should be taken to reduce earthquake damage to non structural components, for example, infill walls in frames.(6)Seismic design methods and construction measures for stairs should be studied.     

Experimental Investigation on Characteristics and Evaluation Indexes of Ground-borne Noise Induced by Subway

In-situ experiments and investigation of evaluation indexes were performed to study the subway-induced ground-borne noise in buildings along the subway lines. The characteristics of ground-borne noise in buildings were summarized from various aspects by analyzing the experimental data. The factors such as the spectrum width, the analyzing time and background noise effect on the results of evaluation indexes, were further investigated. The correlation between different evalution indexes was analyzed, and the deficiencies of the indexes of noise evaluation in the environmental noise control codes of China were discussed.     

Effect of Scheduling Irrigation at Different Phenophases of Sweet Corn (Zea mays saccharata) and Delineation of Critical Stages Based on Stress Day Index

A field experiment was conducted during the summer of 1996 at the Main Research Station, University of Agricultural Sciences, Hebbal, Bangalore to study the effect of phenophased irrigation schedules on green cob and fodder yield and to delineate critical stages based on Stress Day Index. There were seven irrigation schedules consisting of a combination of two IW/CPE ratios (irrigation water/cumulative pan evaporation), viz. 0.6 and 0.8 shuffled at three growth stages: 10–35 DAS (days after sowing), 36–65 DAS and 66 days to harvest in RCBD (randomized complete block design) with four replications. The investigations revealed that all yield attributing characters such as cobs per plant, cob weight, green cob and fodder yields were significantly higher under the irrigation schedule of 0.8 IW/CPE ratio throughout the crop growth. The reduction in green cob and fodder yields were 39 and 25 % respectively, when irrigations were scheduled at 0.6 IW/CPE ratio throughout as compared to 0.8 IW/CPE. Also, frequent irrigation at 0.8 IW/CPE ratio throughout maintained higher plant relative water content (86.90 %) and higher available soil moisture (59.95–81.51 %) before irrigation as compared to delayed irrigations at 0.6 IW/CPE ratio. The quality parameter viz. sucrose content (2900 μg g−1) in developed seeds was also higher under frequently irrigated treatment. The stress day index indicated that vegetative followed by silking and tasseling were the critical stages for moisture stress.
