In this paper two - generation reproduction toxicity of fenvalerate, a - cypermethrin, chlorpyrifos, and triazophos was tested in a 21d period with water flea, daphnia magna, . the toxicity indicator included longevity, body length, days to first brood, days to first pregnancy, number of youth per female, intrinsic rate of natural increase ( r ), and number of broods per female. accordingly, the dose - response relations and relations between the chronic responses and enzyme levels were investigated
為了確定水蚤體內生化指標與慢性毒害效應之間的關系，特別是在低濃度暴露狀態下生化指標改變的生物學意義，以便能更準確預測早期農藥對水蚤種群的潛在危害，本文以浙江省常用殺蟲劑氰戊菊酯、高效氯氰菊酯、三唑磷和毒死蜱進行了大型蚤（ d . magna ）的急性和慢性毒性試驗（包括子代水蚤的恢復試驗） 。( 2 ) taking the geology analysis as main way and combining the pre - test, predicating the tunnel ' s main geology condition ( rock quality, surrounding rock classification, long - wide joint, fault, ground water, crustal stress ), and predicating the main potential disaster ( collapse, breaking water, rockburst, large deformation ) ( 3 ) employing the stress test result and inverse analysis of the stress field, finding out the crustal stress " s distributing rule along the tunnel axes section : the highest crustal stress is 24mpa near the deepest spot, and predicting that the k2 + 260 ~ k3 + 000 likely to be the high crustal stress segment for this tunnel
通過地質分析、類比分析、監控量測、數值模擬、神經網路等方法，對鷓鴣山隧道潛在的主要地質災害（塌方、涌水、巖爆和大變形）進行了預測預報（ 3 ）在現場地應力測試成果的基礎上，運用數值計算進行應力場反演，基本查明了沿隧道軸線剖面的地應力分佈規律：地應力量級在最大埋深附近達到最大值24mpa ，並預測k2 + 260 k3 + 000段將很可能成為鷓鴣山隧道的高地應力段。 （ 4 ）塌方往往與斷層破碎帶及千枚巖相聯系。The hong kong housing society elderly resources centre provides the elderly with comprehensive services to cope with their changing housing needs. through education, the assessment of physical needs and home risks, consultation and research, elderly people can understand change in their physical well - being with age and the potential hazards at home to reduce home accidents
為照顧長者隨著年紀增長而轉變的房屋需要，香港房屋協會的長者安居資源中心提供全面的安居綜合服務，透過教育、身體機能測試、家居風險評估、諮詢及研究，讓長者正確認識身體機能隨年紀的變化，了解家居生活中的潛在危險，以減少發生家居意外。Accordingly this thesis conducts research on the design and management of swimming pools from the running management of its disinfection, reasons and precautionary measures of its water quality mutation in summers and autumns and its water - saving and energy saving. through the participation of the field running management, the literature search, the actual running experience and the theoretical analysis, this thesis forwards drainage & water supply optimization rules for swimming pools. based on field investigation and research on the filtration speed improvement in pressure filters, it is pointed out that there is a wide filtration speed improvement range in pressure filters
鑒此，該課題從消毒殺菌的運行與管理、夏秋季游泳池水質突變的原因及防治措施以及運行過程中節水節能措施等三個方面對游泳池的運行管理模式進行了研究；通過參與現場管理與文獻資料的研究，結合實踐經驗，進行理論分析，提出了游泳池給水排水的優化設計原則；經現場測試，對壓力過濾器提速進行了研究，指出相對于目前規范值有較大提速潛力；討論分析設計了大型多功能游泳場館水處理間自動化控制管理系統。It was shown that when the soil pressure on the stepped rsrw was relatively small, its distribution form was zigzag, and would be affected evidently by unloading function of the step ; the potential fracture surface of the stepped rsrw was obviously different from the 0. 3h fracture surface proposed by the usual hypothesis, and would change with height - width ratio of the wall ; finally, its deformation characteristics were different from the vertical rsrw with single step
測試表明：臺階式加筋土擋墻的墻後土壓力較小，呈鋸齒形分佈，明顯受臺階卸載的影響；潛在破裂面與0 . 3h破裂面假定有較大差異，並隨擋墻的高寬比變化而變化；變形特徵不同於單級直立式擋墻。It is a serious issue that water and nitrogen input rates are unreasonable high in vegetable production in china, which may increase nitrate accumulation in vegetable and ground water contamination. in result, these will be harmful to people ' s health. the objectives of this paper which based on column % pot and micro - plot experiments were to compare the effects of different water and nitrogen supply strategies on nitrogen leaching in the soil profile and nitrate accumulation in vegetable as a base for the n and water recommendations in vegetable production
針對蔬菜生產中水氮投入過量造成蔬菜品質下降、地下水硝酸鹽含量超標，水、肥資源的浪費以及給人體健康造成的潛在性威脅的實際情況，以油菜和芫荽為研究對象採用模擬土柱、盆栽和田間微區試驗相結合方法系統監測了蔬菜生育期內硝酸鹽含量的動態變化以及收獲后不同土層土壤硝態氮的殘留量，研究了水氮對蔬菜硝酸鹽累積的影響及對土壤硝態氮殘留的效應。Thus, reuse of automatically generated and maintained script steps is a workable reality in manual tester that has the potential to save significant amounts of usually scarce test department resources
這樣，重用自動生成和維護的腳本步驟，在manual tester中就變得真實可行了，它就具有了保存大量稀缺的測試部門資源的潛力。分享友人
