In general , fireproof design is considered by architects not by structure engineers . after fire , we compare the fireproof time of the component with the fireproof limit supplied by standards to design 在进行建筑设计时，防火问题一般由建筑师考虑，结构工程师考虑的问题不多；发生火灾后，通过比较试验测得的构件耐火时间与规范所给耐火极限来进行耐火设计。
In order to improve water resources use efficiency in minqing oasis , trial of irrigating cotton is done by three different ways , which is drip irrigation , semifixation spray irrigation and seepage - preventing ditch irrigation 摘要为了提高民勤绿洲水资源利用率，在该地区棉田进行了滴灌、半固定式喷灌和渠道防渗灌溉3种不同灌溉模式的节水综合效益比较试验。
For there is no anti - cpti antibody to use for the assay comparing with the antibody which was obtained by nucleic acid immunization , the work that the cpt / qene was expressioned in e . co / / ar d purified the protein for antibody preparation was carried out at the same time 鉴于没有现成的抗cpti抗体与我们获得的核酸免疫抗体进行比较试验，本研究同时进行了cpti基因的细菌表达与蛋白纯化用于抗体制备。
The local search procedure based on several critical block based neighborhood structure is hybrid with aco _ stag algorithm , comparisons with other well - performed algorithms on taillard ' s benchmark problems show that the hybrid algorithm performs better 给出了fiowshop问题的几种基于关键路径的邻域结构，并把蚁群算法与邻域搜索相结合构成混合算法，与其他算法在taillard流水作业调度测试问题集上的比较试验表明，混合算法性能更优。
By using the attribute clustering analysis through turf vegetation index , 15 tested turfgrasses could be divided into 3 groups ( non - sensitive , medium sensitive and sensitive ) , and then , by using the sulphur content in leaf and turf vegetation index as grouping factors , the tested turf grasses were further divided into 3 groups ( strong tolerance , medium tolerance and weak tolerance ) 在比较试验后发现，草坪草对氟污染的反应不同，用草坪植被指数作属性进行聚类分析，将15种试验草坪草划分成了不敏感，较不敏感和敏感3个反应类型，以草坪草叶片含硫量和草坪植被指数作属性进一步聚类，划分出了强抗性，中抗性和弱抗性3个抗性类型。
Hostas , as important landscape plants used for ground cover in the forest , have been planted in europe and america countries for many years . being ornamental value of flowers and foliages , broadly adaptable and shade tolerance , hostas have been broadly applied for landscape use in china in recent years . based on systemically analysis of hosta germ plasm resource , cultivar resource , and the status of multipropagation technology and chimera researches , some investigation and experiments have been done in this article , including tissue culture , chimera characteristics , production and applying status of hostas in china 本文在较为全面、系统地分析玉簪属植物种质资源与品种资源、扩繁技术和嵌合体研究问题的基础上，以几种玉簪属植物和花叶玉簪的主要园艺品种为试材，进行了组织培养快繁的比较试验；并利用植物生理生化与形态解剖学手段，对性状稳定且具有推广价值的花叶玉簪品种h . ‘ sosweet ’进行了嵌合体特性的研究；本文还对玉簪属植物在国内的引种、生产和应用现状进行了调查、分析。
The results indicate that : only with a few rain gauges to adjust the radar estimated rainfall , authors could simulate the runoff as good as that from rain - gauge - network - measured rainfall ; the accuracy of radar rainfall estimation to heavy rain acts as a more important role than that of light rain ; the estimation error of amount precipitation over a period can be treated as an index for runoff simulation ability 在1500小时时间序列的比较试验表明，雷达估测面雨量和雨量计测量的面雨量都能较好地模拟每小时流域出口蒋集的出流量，数值试验还表明，雷达估测面雨量在某一时段上的均值误差作为一个指标可以较好地反映其应用于降水径流模拟时的精度总雨量和强降水的估测精度是雷达估测面雨量能否用于径流模拟的关键。
