Recently, the chinese plant protection agencies reported the growing hardships in controlling some field populations of oriental migratory locust with organophosphate ( op ) compounds. up to now there are more than 600 arthropod species with documented resistance to one or more insecticides and / or acaricides since resistance phenomenon was first described in san jose scale to lime - sulfur in washington in 1908. enhanced metabolic detoxification and reduced sensitivity of insecticide target - sites are the two major mechanisms in resistance development, involving three primary metabolic enzymes of esterases, glutathione s - transferases and cytochrome p450 polysubstrate monooxygenases
代謝抗性是指對殺蟲劑起水解或隔離作用的酶發生改變，從而對殺蟲劑起到解毒作用，昆蟲主要解毒酶系有酯酶、谷胱甘肽- s -轉移酶、細胞色素p450單加氧酶等，這三種酶系任何一種的組成部分發生改變均會引起害蟲抗性的改變；靶標抗性是指由於殺蟲劑作用靶標敏感度降低而產生的抗性。 -

Secondly, based on the microbeam analytical technique, on the one hand, through investigating the characteristic of major elements in the mantle minerals the author acquired the static information from mantle ; on the other hand, through multi - point analysis of a part of the minerals from mantle, the auther got dynamic information from mantle. finally, generalizating the fruits of this study and predecessors, the autor holds that the constituents of lithospheric mantle possibly includes spinel lherzolites, clinopyroxenites, websterite, dunite, harzburgites, garnet lherzite, phlogopite lherzite, eclogites, clinopyroxene megacrysts ; compared with east china and north china platform, the research field mantle shows the characteristics of higher degree of partial melting processes and more depleted mantle ; the. upper mantle beneath north hetian area is heterogeneous, with a tendency of deficit in a12o3 and lree from kaliyang in west hetian to the river basin of kalakshi river and yulongkashi river ; the subduction of the crust beneath north hetian has ever occurred in geological history and caused the mixing of mantle - crust ; the depth of the origination of basaltic magmas beneath north hetian exceeds 73km ; the thickness of the lithosphere beneath the research area amounts to 204. 9km ; the mantle beneath north hetian has geological condtions for forming diamond deposits
最後，綜合本區幔源礦物和地幔巖石的特徵以及地球物理資料，得出如下結論：本區上地幔的物質組成有尖晶石二輝橄欖巖、二輝巖、單斜輝石巖、純橄欖巖、方輝橄欖巖、石榴石二輝橄欖巖、金雲母二輝橄欖巖、榴輝巖；與中國東部以及華北地臺上地幔相比，研究區上地幔具有富集主元素中相容元素和虧損其中的不相容元素的特徵，局部熔融程度較高；上地幔存在橫向和縱向的不均一性，從西部的克里陽到喀拉喀什河和玉龍喀什河流域， al和lree富集程度呈下降趨勢，不同來源的相同礦物中主元素的含量差異較大；地質歷史時期這里可能發生過地殼俯沖並產生殼幔混合作用；玄武巖漿的起源深度73km ；從幔源重砂礦物的溫壓估算結果，可以推斷出巖石圈厚度可達204 . 9km ；綜合巖石圈物質組成特徵、巖石圈熱狀態、地幔溫壓狀態、氧逸度以及幔源巖石和幔源礦物的化學成分，認為研究區具備了金剛石成礦地幔地質條件。 -

前段時間，教育部門組織體育教師對中小學實施新課標改革情況進行調查，調查表明，一些學校由於辦學規模小，特別是一些農村小學，沒有運動場地，或者對體育鍛煉不夠重視等等，沒有很好地按照新課改要求開足體育課，由於升學制度的制約，一些學校無視學生體育活動和身體健康，有些高年級的體育課貫用「偷梁換柱」的做法，外排體育課，內上文化課，目前多數中小學體育場地布局、器材設施陳舊、緊缺，根本無法保證學校正常的體育活動的開展，更難以說適應新課材的要求。 -
