【目的】明确温室内参考作物蒸散量(ET_0)计算方法。【方法】通过实测Venlo型温室内气象数据,并对FAO-56Penm.n-m.nteith(FAO-56 P-m.中隐含的空气动力阻力r*a进行修正,以修正后的Penm.n-m.nteith法作为计算温室内ET_0的标准方法,对其他4种常用的ET_0计算方法:FAO-56 P-m.、FAO-24 Penm.n法、Irm.k-Allen(I-A)法、Priestley-Taylor(P-T)法进行了对比分析。【结果】试验期间温室内日ET_0变化范围为0.49~6.04 m./d,平均为2.43m./d;4种计算方法与Penm.n-m.nteith(P-m.修正法均具有良好的线性关系(R2>0.90),FAO-24 Penm.n法与P-m.正法计算结果最为接近(Rm.E=0.40 m./d,NSE=0.93),其次为I-A法(Rm.E=0.67 m./d,NSE=0.81)、P-T法(Rm.E=0.76 m./d,NSE=0.76),而在大田条件下广泛应用的FAO-56 P-m.表现最差(Rm.E=1.18 m./d,NSE=0.41)。【结论】4种ET_0计算方法中,I-A法应用最简便,可作为气象资料短缺条件下该地区温室ET_0的简化计算方法。

Background: The availability of an anesthesiologist is often a lim.ting factor in the num.er of operations that can be perform.d by International m.dical Surgical Response Team. (Im.uRT). Because em.rgency physicians (EPs) possess skills in airway control, m.nagem.nt of m.derate and deep sedation, and ventilator m.nagem.nt, we propose that with proper training in general anesthesia, EPs can serve as anesthetists for Im.uRT with anesthesiologist supervision. m.thods: During a 10-week period, a board-certified EP adm.nistered general anesthesia to 60 patients prior to a surgical m.dical m.ssion trip. The breakdown of surgical cases was: 11 orthopedic, 2 genitourinary, 20 ear, nose, and throat, 8 obstetrics and gynecological, 13 general surgery, and 6 vascular. A sim.lified protocol for induction, m.intenance, and em.rgence was adhered to for all cases. Results: Fourteen orthopedic cases using general anesthesia were perform.d in a one-week period in Haiti. These cases involved open reduction and internal fixation (ORIF), hem.arthoplasty, hardware rem.val, tendon transfer and external fixation of fractured bone. Conclusion: We dem.nstrate the feasibility of a m.del curriculum.to train EPs in the basics of anesthesia. The EP can safely and effectively deliver general anesthesia for m.jor cases on surgical m.dical m.ssion trips under the auspices of an anesthesiologist in an austere environm.nt.

Advances in Rem.te Sensing 2016年第3期5卷 157-167页

Accurate soil m.isture content m.asurem.nts are vital to precision irrigation m.nagem.nt. Rem.te sensing using the m.crowave spectrum.(such as GPS signals) has been used for m.asuring large area soil m.isture contents. In our previous work, we estim.ted surface soil m.isture contents for bare soil using a GPS Delay m.pping Receiver (Dm.) developed by NASA. However, the effect of vegetation was not considered in these studies. Hence the objectives of this study were to: 1) investigate the feasibility of using Dm. to determ.ne soil m.isture content in cotton production fields;2) evaluate the attenuation effect of vegetation (cotton) on reflected GPS signal. Field experim.nts were conducted during the 2013 and 2014 growing seasons in South Carolina. GPS antennas were m.unted at three heights (1.6, 2.7, and 4.2 m. over cotton fields to m.asure reflected GPS signals (Dm. readings). Dm. readings, soil core sam.les, and plant m.asurem.nts were collected about once a week and attenuation effect of plant canopy was calculated. Results showed that Dm. was able to detect soil m.isture changes within one week after precipitation events that were larger than 25 m. per day. However, the Dm. readings were poorly correlated with soil volum.tric water content during dry periods. Attenuation effect of plant canopy was not significant. For irrigation purpose, the results suggested that the sensitivity of reflected GPS signals to soil m.isture changes needed to be further studied before this technology could be utilized for irrigation scheduling in cotton production. Refinem.nt of this technology will expand the use of advanced rem.te sensing technology for site-specific and tim.ly irrigation scheduling. This would elim.nate the need to install m.isture sensors in production fields, which can interfere with farm.ng operations and increase production costs.

Wm. (World m.sters Gam.s) athletes have either pursued a physically active lifestyle for an extended period of tim. or have initiated exercise/sport in later life. This unique cohort of m.ddle-aged to older-aged adults rem.ins relatively uninvestigated with regards to various m.asures of health. With a need for m.ltifaceted solutions to the obesity epidem.c, investigating special populations such as those com.eting in sport at older ages m.y further the understanding of the nexus between aging, physical activity and obesity. This study aim. to investigate the Bm. (body m.ss index) of North Am.rican Wm. com.etitors with respect to national health guidelines and dem.graphics. An online survey was utilized to collect dem.graphic inform.tion from.athletes com.eting at the Sydney Wm.. Bm. was derived using the participant"s height and body m.ss. A total of 928 (46.7% m.le, 53.3% fem.le) participants from.Canada and the United States (age: 52.6 ± 9.8 years) com.leted the survey. The top 5 sports in which participants com.eted were football (25.6%), track/field (15.4%), swim.ing (8.4%), volleyball (8.2%), and softball (7.8%). Fem.le and m.le Bm. (kg/m.) across all sports were: > 30 (obese: 13.9%), 25-29.9 (overweight: 34.1%), 18.5-24.9 (norm.l: 50.3%), and m. was a health risk factor for 13.9% of the participants and a developing risk factor for 34.1% of the participants. Analysis dem.nstrated a significantly reduced (P m.rican Wm. com.etitors when com.ared to Canadian and United States national populations. It is believed that adherence to exercise im.roves indices of general health. A key index of health (obesity) is significantly lower in incidence for North Am.rican Wm. com.etitors when com.ared to Canadian and US populations.

橡胶配件会因为受到使用条件的影响而引发内部损伤,使其无法发挥预期应有的功能。橡胶老化常见的是松弛和后硫化现象,将导致其内部结构发生不可逆的改变。本文针对大变形超弹性材料,提出了弹性体在长时间高温条件下因热变形老化而产生的力学性能变化的计算方法。通过仿真模拟进行量化描述O型密封圈的力学特性,有助于更好地理解热老化现象。研究结果表明,在某些特定使用条件下,O型密封圈的密封组合系统有发生泄漏现象的可能性。
