＜正＞Improving water use efficiency is crucial to both Australia and China. In the case of China, development in the last half century has resulted in the irrigated area growing from 16.0 Mha to 55.9 Mha which accounts for 42.4% of the farmland. The total water use for irrigation in China gradually increased from approximately 100 BCM in 1949 to 358 BCM in 1980, after which, it has since stabilised. However, competition for water from other sectors is increasing. For example, industrial and municipal water use has increased rapidly and reduced the proportion used in irrigation to 92, 80 and 60% in 1949, 1980 and 2003 respectively. This situation demands major improvement in water use efficiency for irrigated agriculture if current production levels are to be enhanced or maintained. Irrigated agriculture makes up 70% of Australia’s consumptive water use. With the water resources in irrigation areas being close to fully allocated, or even over-allocated in some catchments, there is an increased competition for water. It is generally accepted that there will be less water available for irrigated agriculture in the future and the only way to provide enough water for irrigation will be to use the available resource more efficiently at both farm and catchment scales. In both China and Australia, it is hardly possible to withdraw more water from existing resources;the present irrigation practices and future irrigation developments should focus on improvement of water use efficiency in all sectors at all scales. However, savings from one part of the system may lead to higher water use in another part of the system and the overall improvement may be negligible. Some measures that may improve the water productivity in agriculture are canal lining, irrigation scheduling, high-tech irrigation technologies, improved cropping patterns and conversion to crops with higher economic returns. The key to achieving "real" and substantial water savings lies in the assessment and hydrologic

Modification in Cu-Zn Alloy Properties by 2 MeV Ni<sup>+</sup>Ions Irradiation

引用

Materials Sciences and Applications 2018年第3期9卷 330-344页

作者： shahbaz Ahmad Shazia Bashir Daniel Yousaf Mian Ahsan Ali Department of Physics University of Sargodha Lahore Campus Lahore Pakistan Center for Advanced Studies in Physics Government College University Lahore Pakistan

We investigate the effects of 2 MeV Ni+ ion beam irradiation with various fluence ranging from 15 × 1011 to 60 × 1014 ions/cm2 on the surface, structural and mechanical properties of Cu-Zn alloy. The modification in target properties after irradiation is confirmed by using various characterization techniques viz. SEM, XRD, UTM and Vickers micro-hardness tester. The SEM results illustrate the formation of nano sized craters with different diameters. Their average diameter decreases from 190 nm to 90 nm by increasing ion fluence. The XRD analysis of irradiated targets reveals that Ni+ ion irradiation enhances the growth of (111) phase and its peak position varies due to ion induced tensile stresses in target matrix. Tensile and Vickers micro-hardness tests verify the mechanical properties of Cu-Zn alloy reduce monotonically upon irradiation. Various mechanisms such as generation, recombination, augmentation and annihilation of ion induced defects are responsible for this reduction. Understanding the relationships between various modified properties of irradiated target is essential for growing new advanced material by irradiation.

Surface Analysis Correlated with Structural and Mechanical Properties of Laser Irradiated Brass

引用

Materials Sciences and Applications 2015年第1期6卷 23-32页

作者： shahbaz Ahmad Shazia Bashir Daniel Yousaf Nisar Ali Tousif Hussain Center for Advanced Studies in Physics Government College University Lahore Pakistan

Brass targets were irradiated with various laser pulses of Excimer laser ranging from 1200 to 3000 for constant fluence of 3.4 J/cm2 in oxygen atmosphere (100 Torr). The surface morphology and crystallographic analyses were performed by using Scanning Electron Microscope (SEM) and X-Ray Diffractometer (XRD). SEM analysis reveals the formation of laser-induced micro-sized cavities, bumps, cones and wave-like ridges with non-uniform shape and density distribution. These features are formed for all number of pulses;however with increasing number of pulses from 1200 to 2400, the density of cavities decreases whereas, the wave-like ridges become more pronounced and bump-formation is vanished. For maximum number of 3000 shots, the appearance of cones and wave-like ridges becomes diffusive, whereas the density and size of cavities increase again. XRD analysis demonstrates that no new phases are formed in irradiated brass. However, the change in peak intensity along with lower and higher angle shifting is observed which is attributed to generation of laser induced stresses. The Yield Stress (YS), Ultimate Tensile Strength (UTS) as well as Microhardness increase monotonically with increasing number of laser pulses.

目的:采用新型频域相关断层扫描测量分析健康年轻人中视网膜各参数生理的不对称性。方法:对146名健康年轻人进行横断面观察研究,采用新型频域相关断层扫描对其双眼视网膜参数(视网膜神经纤维层厚度、视盘、黄斑)进行扫描。通过右眼减去左眼所得参数值的平均差进行配对t检验。两眼间的差异采用2.5%~97.5%之间进行评估。视网膜参数相关。通过回归分析,评价性别和血压对视网膜参数的影响。结果:两眼的视网膜神经纤维层平均厚度无统计学差异(+0.7μm,P=0.09)。两眼视网膜颞侧象限(+2.51μm,P=0.02),鼻侧象限(+2.50μm,P=0.04),钟表位右眼2点与左眼10点(+5.85μm,P=0.002),右眼3点与左眼9点(+3.20μm,P=0.005),右眼11点与左眼1点(+3.80μm,P=0.024),平均厚度(-0.034μm,P=0.013)和垂直方向杯盘比(-0.028μm,P=0.008),黄斑部鼻侧象限(+7.76μm,P=0.003)。左眼上方视网膜明显较薄(-2.40μm,P=0.03)。平均视网膜神经纤维层厚度和黄斑厚度分别为11μm和18μm。视网膜参数在双眼有中度的相关性(0.41~0.6),而两眼视网膜参数与性别、血压不相关(P<0.05)。研究表明通过新型频域相关断层扫描发现健康年轻人的视网膜神经纤维层厚度和黄斑厚度两眼间的差异分别不应超过11μm和18μm。结论:视网膜参数的不对称性存在于健康视网膜,并对早期视网膜病变的诊断提供有价值的评估。

提出了一种基于改进YOLOv5n的肉羊攻击行为检测方法.在轻量级网络YOLOv5n的基础上,首先利用Ghost模块卷积替换传统卷积,减少网络参数和计算成本;其次在网络关键位置添加坐标注意力机制(Coordinate Attention,CA),用来增强网络通道信息和位置信息;然后引入EIOU(Efficient Intersection Over Union)损失函数,并进行改进,增强预测框准确性,减少误检情况;最后利用Ranger21优化器替代SGD(Stochastic Gradient Descent)优化器,缓解Ghost模块卷积提取特征不足,加快模型收敛速度.为了提升模型对不同天气泛化能力,对一半数据添加雪天、雨天和雾化3种天气情况.对比试验表明,改进模型是原YOLOv5n基础模型参数的83%,模型大小仅有3 Mb,而准确率提升0.7%,召回率提升1.3%,mAP(Mean Average Precision)提升0.5%,F1提升1.01%,同时优于其他主流基于YOLO轻量级网络模型.

林业与社会 1996年第2期4卷 18-19页

作者： shahbaz Ahman 刘婕

当前,公众参与、乡村发展、参与性经营等问题已受到世界上有识之士的广泛关注。我们认为,公众参与即由村社成员自己来经营现有森林资源。这种方法显示了对村民的尊重和信任,因而增加了村民的自主性,减少了对外部资源的依赖性。

为探讨大田棉花氮代谢随播期和密度的变化规律,选用华棉3109(*** L.)于2014年在华中农业大学试验农场,采用裂区设计:播期(月-日)(S1,05-30;S2,06-14)为主区,密度(株·m-2)(D1,7.5;D2,9.0;D3,10.5)为副区,研究了硝态氮含量在主茎叶柄和根系的分布特点。结果表明:1)随生育进程推进,叶柄和根系硝态氮含量先升高后降低,初花期最高。2)主茎叶柄硝态氮含量随叶位变化,蕾期、初花期由上而下逐渐降低,第1叶最高;盛花期逐渐增高,第1叶和第4叶最高;不同生育时期棉花叶柄硝态氮含量在叶位间的下降幅度随播期推迟而降低,随密度增加先升高后降低。3)播期和密度对不同生育时期棉花叶柄和根系硝态氮平均含量的交互作用均显著,但播期和密度主效应影响不同:见花施肥前,随推迟播期,棉花叶柄硝态氮平均含量显著降低了42.9%,根系硝态氮平均含量显著升高了12.1%,增加密度对叶柄和根系硝态氮平均含量无显著影响。见花施肥后,随播期的推迟,叶柄硝态氮平均含量无显著性变化,初花期平均为5.05 mg·g-1,盛花期平均为2.62 mg·g-1;而根系硝态氮平均含量,初花期S1>S2,盛花期S1
