中文拼音 [zhìjīqiángdù]
致畸強度
英文
teratogenic potency-
The protein nucleic acid complexes were identified by autoradiography for 48 h. the psg5heo and igfbp - 6 promoter pcat vectors were transfected into cos - 7 cells with iipofectamin2000 ; these cos - 7 cells where treated with 1 jxm e2, with lonm tcdd and with both lonm tcdd and 1 jxm e2, individually ; the cat protein was examined by cat - els a. results : the congenital skeletal defects in fetal rats were induced with 10 - 15ug / kg tcdd or with 100 - 140 mg / kg ra with dosage - dependence effect. the igfbp - 6 mrna in rat calvaria tissue and mc - 3t3 - el cells were increased with tcdd and ( or ) ra, whereas the cell proliferation and igf - 2 mrna in mc - 3t3 - el cells was decreased in the status of e2
結果: tcdd在大鼠胚胎發育時期具有骨骼致畸作用，骨骼發育畸形包括:內翻足、脊柱裂、顱面骨發育缺陷、無尾畸形等;隨著tcdd濃度的升高（ 10一15林擴kg ） ，致畸率明顯上升（ 14 . 7 %一24 . 6 % ） ; tcdd和ra聯合用藥可以增強對大鼠骨骼發育的致畸效應; e :對成骨細胞內igf一2基因有正性調節作用，對igfbp一6基因有負性調節作用， tcdd可以抑制e :對細胞內xgf一2和igfbp一6的調節作用。The temperature dependences on the resistance in all the thin films show that in the low temperature range the width of eg band level changes the transports, but in the high temperature range the thin films forms the small polarons hopping conductivity. the phase transition induced by the current is explained by the demagnetization and lattice distortion
在高溫部分，材料呈現小極化子跳躍形式輸運特徵；實驗研究了不同偏置電流對薄膜的相變影響，表明電場可以引起材料中磁性的變化和晶格畸變，導致相變溫度點向低溫方向移動；材料的光致相變研究表明光子能量、光強和極化方向對輸運性質有影響。But, the alarm signals from scada have disadvantages as follows : ( 1 ) the open - air feeder terminal units ( ftu ) are interfered by strong electromagnetic and thunder. besides, the failure of relays and the fault of ftu can also lead to that fault information is interfered and aberrant. ( 2 ) in the process of transmission and commutation, the error in the communication equipment may result in the signals err or lose
然而，現有的scada系統在配電網發生故障時提供給調度員的警報信息有如下局限性： （ 1 ）面向現場的戶外饋線終端ftu運行環境惡劣，承受強的電磁、雷電干擾，並且由於繼電器節點故障、 ftu元器件損壞等因素的存在，使得配電網信息受干擾、畸變的可能性較高； （ 2 ）在信號傳輸及變換過程中，通訊裝置的故障等原因，也可能導致信號出錯甚至丟失； （ 3 ）保護裝置和斷路器本身也有可能誤動或拒動。But influenced by a great deal of factors in laser and only strong stability scanning as one again, for instance, the un - stability of laser instrument, inconsistency of decaying to the laser of every part, etc. in the scanner, can lead to the fact intensity of laser on piece fluctuate, cause, scan systematic formation of image quality drop finally
另外，又針對激光掃描系統中的由於掃描非線性等固有因素的存在，所導致掃描成像灰度畸變的現象，提出了一種利用數字補償校正技術對固有因素進行激光光束光強的逐點補償的新方法。本設計不僅適用於激光掃描系統，對于其它各個應用領域，都有參考價值。分享友人
