Ryanodine receptors（RyRs） activator has become one class of popular insecticide because of its unique mode of action. In order to find more new RyRs activators as insecticidal agents, a series of 18 novel chiral anthranilic diamides were designed by introducing the D-alanine acid and D-serine acid esters as well as trifluoroethoxyl group into the anthranilic diamide skeleton and synthesized successfully based on anthranilic diamide and FKI-1033 structures. The structures of the title compounds Ia–i and IIa–i were confirmed by melting points,~1H NMR,^（13）C NMR, elemental analysis and specific optical rotation *** preliminary bioassay results indicated that most of the title compounds exhibited considerable larvicidal activities against oriental armyworm at 10 mg/L, especially Ib, Ie and IIh showed remarkable insecticidal activities at 0.5 mg/L. The larvicidal activity against diamondback moth of Ia and IId were 80%and 90% respectively at 0.0001 mg/L, which was similar to that of chlorantraniliprole. The relationship between structure and insecticidal activity was analyzed to reveal a possible co-regulated effect of the chiral amino acid ester, halogen atom or cyano group, and trifluoroethyloxyl group of the skeleton structures of the title compounds, which will provide useful information for guiding the design and discovery of new RyRs activators and insecticidal agrochemicals.

Chinese Journal of Chemistry 2017年第3期35卷 368-374页

In order to discover potential ryanodine receptor insecticides, 21 novel anthranilic diamides analogues ( C , D , E , and F ) containing amide, carbamate, urea, and thiourea moieties were designed and synthesized based on bioisosteric approach. The biological assays against oriental armyworm ( Mythimna separata ) and diamondback moth ( Plutella xylostella ) indicated that these compounds displayed moderate to excellent activities. Especially, compound D 1 showed 100% larvicidal activities against oriental armyworm at 1.0 mg•L −1 , equivalent to the standard chlorantraniliprole (100%, 1.0 mg•L −1 ). Moreover, the larvicidal activity of D 1 against diamondback moth was 100% at 0.1 mg•L −1 , more effective than that of chlorantraniliprole (90%, 0.1 mg•L −1 ). Therefore, D 1 can be used as a new lead structure for the development of insecticidal agents. The preliminary structure‐activity relationship showed that the introduction od carbamate groups into 4‐position on the benzene ring of the N ‐phenylpyrazole moiety has a positive effect on the larvicidal activities.

Chinese Journal of Chemistry 2018年第2期36卷 129-133页

The sulfoximine group has been evaluated as a pharmacophore. Introducing the sulfoximine structure into medicinal compounds as exciting motifs has brought opportunities in drug discovery. In order to develop new ryanodine receptor （RyR） modulators, a series of phthalamides containing sulfoximine derivatives were designed, synthesized, and evaluated against oriental armyworm and diamondback moth for their insecticidal activities. These studies helped to elucidate the electronic and structural requirements around the sulfoximine motif for insecticidal activity. All new structures were synthesized and characterized by ^1H NMR, ^13C NMR, HRMS and bioassay and a preliminary structure-activity relationship （SAR） was discussed. The biological assessment indicated that most title compounds showed good to excellent larvicidal activities. Compounds la, le, and If gave excellent insecticidal activity against oriental armyworm, which showed 100% larvicidal activity at 0.5 mg/L. All compounds showed 100% larvicidal activity at 0.1 mg/L against diamondback moth. In particular, the larvicidal activities of le, If, and lh at 0.0001 mg/L were 50%, 20%, and 40%, respectively, reaching an activity as high as that of the commercial flubendiamide （40%, 0.0001mg/L）. Therefore, Ia, Ie, If and Ih could be considered as new lead structures for the development of new ryanodine receptor （RyR） modulators.

Two series of N-pyridylpyrazolecarboxamide derivatives were designed and synthesized by introducing D-alanine acid esters and D-serine acid esters into the skelecton of chlorantraniliprole. The obtained structures were characterized by 1H NMR, 13C NMR, elemental analysis and specific optical rotation analysis. Preliminary bioas-says indicated that some compounds displayed excellent insecticidal activities against Mythimna separate and Plutella xylostella in comparison with chlorantraniliprole. In particular, IIq showed excellent insecticidal activity against Plutella xylostella with a mortality rate of 90% at 0.01 mg·L^-1. A 3D-QSAR （CoMSIA） study was per- formed in order to disclose the insecticidal structure-activity relationship and indicate the future work. The CoMS1A study demonstrated that large substitutes and electron deficient groups at the 3-position of pyrazole ring are favora- ble, the same as a small group near the ester groups of amino acid.

新乡市平原路隧道为双向4车道,下穿既有建筑物610.55 m,与既有建筑物底板净距仅2.0~4.5 m,属浅埋大跨隧道下穿既有建筑物工程,施工难度非常大。根据工程类比,提出了分离式、双连拱和双孔矩形等隧道断面形式,通过数值模拟分析既有建筑物受影响的规律,最终确定采用双孔矩形隧道,CRD法施工,并提出了双孔矩形隧道的优化方案：双孔矩形隧道与地下商业街紧贴,充分利用商业街作用,施工中辅以适当范围的超前注浆措施,但设计参数不宜过高,否则不但施工中难以实现,而且对提高加固控制变形的效果不明显。研究成果可为其他类似工程设计提供一定的借鉴。

根据动力时程分析理论，采用岩土隧道结构专用有限元分析软件GTS，对新建上跨隧道爆破施工工程进行三维有限元数值模拟，研究新建上踌隧道爆破施工对既有隧道的影响。结果表明：既有隧道与新建上跨隧道交叉处的断面受到垂直方向振动的影响最夫，随着离爆破点水平距离的增加．垂直方向的振速逐渐减小。水平方向的振速先增大后减小，爆破施工对位子交叉点水平距离25m之内的既有隧道影响较大，对45m以外则影响很小；爆破进尺需控制在1，5m以内。并辅之以相应的工程措施，以保证既有隧道安全；新建隧道爆破施工过程中，需对既有隧道K201＋065-K201＋165段拱顶垂直振速进行监控量测。

儿童游憩空间在快速城市化背景下日益显示出其重要性,儿童的游憩体验也备受学者的关注。该研究以广州市儿童公园为案例地,采用照片引谈法和参与式观察法,尝试探究儿童视角下的儿童游憩体验。研究发现,广州市儿童公园的儿童游憩体验类型主要为3种:基于感官愉悦的感官式体验、基于认知的判断式体验和追求互动的社交式体验。影响儿童游憩体验的因素主要包括3方面:游憩设备与空间环境、儿童幻想与社会认知以及同伴关系。其中,在同伴关系中,区别于以往监督者的角色,家长的陪伴者角色更加突出,亲子间的亲密交流互动、强凝聚力的家庭氛围培养同样影响儿童的游憩体验。基于此,园区应选择高参与度、高安全性的游憩设备,提高游憩空间的功能可供性,提供符合儿童审美的游憩环境,并考虑游憩空间按年龄分区的管理模式促进儿童积极的游憩体验。园区应设置更多合作型游憩设备,提供亲子间交流合作的空间和机会。研究以期丰富儿童游憩体验以及儿童地理学的相关研究,并为城市儿童公园的规划和建设提供建议。
