动物诊疗机构人用药品使用现象分析及建议

随着社会经济水平日益提升,越来越多的人饲养宠物作为伴侣,与此同时宠物诊疗机构如春笋般蓬勃发展。然而其在发展中存在诸多问题,尤以使用人用药品问题最为突出。论文从药品使用现状、原因、管理等方面,对动物诊疗机构人用药品使用现象进行分析并提出一些建议,旨在进一步规范动物诊疗机构临床用药,使其良性发展。     

巢湖沿岸圩区稻季营养盐的输出特征研究

巢湖流域沿岸分布着很多圩区,人们在圩内进行各种农业活动,圩区营养盐的输出是造成巢湖流域非点源污染的重要因素。为了解圩区农业非点源营养盐的输出特征,笔者通过在巢湖流域河网地区选择比较典型的圩区,于2014年水稻生长期进行了较系统的野外调查观测、取样和室内水质分析,探讨在自然降雨-径流的条件下圩区各类营养盐的浓度变化及输出特征。2014年稻季共进行了9次排水,排水量总计73.09 mm,径流系数为0.37,9次排水事件总氮(TN)和总磷(TP)的平均浓度分别是3.42、0.22 mg/L,圩区水体处于富营养化水平。降雨-径流强度是影响营养盐浓度变化的重要因素,稻季生长期内TN和TP的输出量是0.28、0.017 kg/hm2,占稻季施肥总量的1.7%和0.16%。径流量是影响营养盐输出总量的关键因素,同时施肥量和施肥至排水事件的间隔天数也是是影响营养盐输出的重要因素。     

Some Ideas on Reconstruction of Villages inside the City

In this paper, the historical reasons of formation of the village inside the city are analyzed. It is indicated that such situation for the villages inside the city are the result of joint action of both the villagers and the government. The foundation of villages inside the city laid on the simple compensation for farmers in confiscating the rural land and lack of intelligence aids. In this paper, the ideas and measures for their reconstruction are put forward based on consideration of the reasons of their formation and difficulties in the reconstruction.     

PROBABILISTIC EVALUATION FOR STEEL FRAME COLUMNS OF TALL BUILDINGS

Based on properties of parameters and test data of dom-estic steel,this paper analyses the reliability and partial coefficient forresistance of steel frame columns of tall builings.The result may serveas a scientific basis.It is not only for domestic steel instead of importedsteel in building tall steel structures,but also for compiling concerendstandards.     

The Software System for Computation and Drawing of Ship Properties

The softwa re system suggested in this paper is applied to replace the traditionalhanded-computation forms. It uses the cubic sample interpolation and numerical integral,and is writ-ten with FORTRAN according to the accurate formula. With this software system,the nine sorts ofcomputation results of ship properties can be obtained. The system is con nected through SCR filewith AutoCAD,and ean draw automatically eleven sorts of pictures according to the computation re-sults.     

The Monitoring Measurements and Country Rock Control of NATM in Tunnel of Express Road during Construction

In this paper the author' s study on the monitoring measurement technique of NATM,the regularity and conditions of the country rock deformation are analysed based on the site measurement data in the west section of Zhongliangshan tunnel. The regression analysis of measure data for different measure lines of vavious country rock is done by the use of self-compiled CRAP program. The stability criterion for various rockmass and optimum time for primary and permanent support are provided. The conclusion available could conduct the theoretical research of NATM deeply as well as tunnel design and construction.     

A SDUDY ON THE LOCKING PERFORMANCE OF THE SYSTEM FOR HEIGHT OF MG150-WD COAL SEAM SHEARER

In this paper, based on the automatic-control theory, the time and frequency response of the hydraulic control system for height of MG150-WD coal shearer are analysed, and the steady and dynamic locking performance tests are made. The results show that the locking performance is satisfactory.     

玉米自交系及杂交种抗青枯病鉴定

1986-1989年采用自然鉴定和人工土壤接种鉴定的方法，对602份玉米材料的青枯病抗性进行了鉴定。人工接种鉴定397份，其中204份材料表现抗病。在正常年份，人工接种鉴定效果明显好于自然鉴定，但在重病区或青枯病流行年份，在尚未具备人工接种条件时，利用自然发病作为选育抗病材料仍有一定效果。玉米苗期接种青枯病重于成株期     

促芽肥与杂交中稻再生力关系及其作用机理

１９９１－１９９３年以２个杂交中稻品种为材料，研究了促芽肥与杂交中稻再生力关系及其作用机理。结果表明，促芽肥不能提高到２、倒３节位活芽率，可提高倒４、５位活芽率。促芽肥对再生力的效果与母茎 鞘干物质重有关，当母茎鞘干物质过大或过小时，促芽肥的作用极小。     

施肥对早稻品质的影响

为研究施肥对早稻品质的影响,2000~2001年在芦溪县分别进行了N、K不同施肥量和不同施肥方式对早稻赣早籼48与早稻香两优68品质影响的研究。结果表明:出糙率、精米率和蛋白质含量都随着施N量增加而增加,直链淀粉含量随N肥用量增加而略有减少趋势;精米率、整精米率、直链淀粉含量和蛋白质含量随着K肥用量增加而增加;中N(150kg/hm2)、高K(135kg/hm2)处理互作效应最大,比较适合当地优质早稻赣早籼48施用。施肥方式以生物有机肥配合化肥全层施肥,中后期补施穗肥的出糙率、精米率、整精米率和稻米的蛋白质含量都能提高,直链淀粉含量降低。
