The measured bunch length ranging between 1.4 mm and 2.0 mm agrees well with the theoretic calculation of 1.5 mm.The electron beam current measured by the beam current monitor(BCT3) is almost in direct proportion to the induced voltage of the fundamental harmonic.When the parameters of the pre-buncher and buncher are adjusted greatly while the beam current ...

根据不同时刻的记录，基频腔峰值电压与束流流强探测器BCT3所测流强值近似成正比关系；当大幅改变预聚束器和聚束器参数而束流流强不变时，反映聚束质量的五倍频腔信号也随之大幅改变，而反映流强信号的基频腔信号则变化不大，这些试验结果与理论分析完全一致。

The electron beam current measured by the beam current monitor(BCT3) is almost in direct proportion to the induced voltage of the fundamental harmonic.When the parameters of the pre-buncher and buncher are adjusted greatly while the beam current being unchanged,the fifth harmonic signal has a great change,but the fundamental signal changes gently.

A study of phase morphology of PBT/POE-g-MAH/nano-CaCO3 composite by means of scanning electron microscopy showed that the domains size of nano-CaCO3 capsulated by POE-g-MAH elastomer in composite when PBT was mixed directly with POE-g-MAH and nano-CaCO3 together or with nano-CaCO3 capsulated by POE-g-MAH elastomer is large.

采用熔体流动速率较低的EPS30R与纯POE-g-MAH共混制备的增韧改性剂，在PBT基体中的分散相变得粗大且不均匀，共混物的脆韧转变推迟。SEM显示，纯POE-g-MAH增韧剂使PBT共混物发生脆韧转变时，弹性体分散相颗粒产生塑性变形，诱发基体屈服而吸收能量。

Based on the results of this report and the results of literature reports on the preferred conformation of enantiomeric 3-substituted-1, 4-benzodiazepines, a nucleophilically solvated C3 carbonium ion intermediate resulting from either a P or a M conformation is proposed to be an intermediate.

The speed of electrophilic addition reaction of Alkene is inferenced greatly by the electron-withdrawing group or electron-releasing group on C=C of Alkene And the main addition product is decided by stability of carbonium ion.

烯烃C=C上连有供电子基和吸电子基时，对于烯烃亲电加成反应速度的影响是很大的。加成产物是由碳正离子中间体的稳定性来决定。

In no particular order of difficulty, here is a list of the complications facing the young Michelangelo as he approached a block of newly quarried Carrara marble in the late summer of l499, and prepared to embark upon the carving of his first pieta.

这就是年轻的米开朗基罗在1499年夏末走近一块新采的卡拉拉大理石准备开始雕刻第一座《圣母怜子像》时面对的一系列难题。【这是关于米开朗基罗和《圣母怜子像》的看法之一。希望你也能脱口而出

Inflorescence a terminal panicle, raceme, or spike, dense or lax, covered by 1--3 spatulate involucral bracts when immature; bracts open to base, rarely hooded, each subtending 1 flower or a cincinnus of 2 to many flowers; bracteoles open to base or tubular, rarely hooded, sometimes absent.

The result makes clear, matrix scale, into discharge, wet the processing result that does the TN in comparing pair of sewage, TP all has extremely distinct effect, among them matrix (beehive is cindery ∶ vermiculite) scale is 1 ∶ 2, it is into discharge 28.8 L/d, wet dry than be 1 ∶ 5 when, best to the purify effect of TN, TP.

结果表明，基质比例、进水流量、湿干比对污水中TN、TP的处理效果均有极显著影响，其中基质比例为1∶2、进水流量为28.8 L/d、湿干比为1∶5时，对TN、TP的去除效果最好。

The factors affect on the degree of substitution of product, yield and apparent viscosity, such as the mol rates of EPTAC with -NH2, reaction temperature, reaction time and the content of water in system have been discussed in detail. FTIR spectrometer and UV spectrometer are used to characterize the structure of the derivative and it is proved that substitution reaction mainly occurs on the -N element .The particle size and morphology of chitosan and quantemary ammonium salt of chitosan are analysised by comparing photos of their scanning electron microscope. The degree of substitution of HACC is determined by acid -base conductometric titration. An error in current formula of DS has pointed out and a correct formula has presented.On the base of experience of above experiment, the reaction conditions of HACC were systematically investigated through orthogonal design, and then the best conditions are found. Water-solubility and dependence of pH are studied.
