At the same time, the intensity ratio of the ICT fluorescence to the LE fluorescence, I〓/I〓, shows a "bell"-shaped variation with increasing CTAB concentration The intensity ratio was found to level off after the CMC of CTAB Together with the data from UV-Vis absorption spectroscopy, electric conductance measurements and the control experiments with tetramethylammonium bromide, it was concluded that the"bell"-shaped variation in the intensity ratio before CMC is due to the formation of premicelle aggregates consisting of ICT fluorophore and CTAB.

此时，ICT荧光强度与LE荧光强度之比，I〓/I〓随CTAB浓度增大而呈&钟形&变化。当CTAB浓度高于CMC时，I〓/I〓为一常数。根据紫外-可见吸收光谱，电导以及四甲基溴化铵对照实验的结果可知，当CTAB浓度低于其CMC时，I〓/I〓的&钟形&变化是由于长链对二烷基氨基苯甲酸与CTAB组成的胶束前簇集体形成所致。

Objective This study evaluated clinical value of inferior ST segment depression in acute transmural anterior myocardial infarction.

目的探讨急性前壁透壁性心肌梗死时下壁导联ST段压低的临床价值。

Methods Serum CEA and CA19-9 were detected by radio immunoassay in 38 patients of observation group with cholangiocarcinoma and carcinoma of ampulla before endoscopic retragrade cholangiopancreatography, took 5 ml bile to detecte CEA and CA 19-9 While ERCP, and took endoscopic biopsy for histopathological with the help of wise, recorded the feature of imaging. Bile CEA and CA19-9 were detected in 30 patients with unmalignant of contrast group in the same way.

观察组38例肝外胆管癌及壶腹癌患者在行ERCP检查前检测血清CEA及CA19-9，行ERCP检查时经造影导管抽取胆汁5ml用放免方法检测CEA及CA19-9，同时在导丝引导下自胆管咬取活检行病理检查，并记录影像学特征；同样，对照组30例非恶性病变患者在行ERCP检查时抽取5ml胆汁检测CEA及CA19-9。

At the designed operating frequency, the refractive index approximates zero, which makes the nondirective electromagnetic wave tend to approximate plane wave along the normal direction of the superstrate and congregate the radiation energy. The gain patterns of the rectangular waveguide antenna and arrays with and without DNG structure are compared.

比较了双负媒质结构加载前后矩形波导天线及其阵列的增益方向图，数值仿真和测量结果表明，天线的前向增益得到显著的提高，同时对后向辐射也有一定的抑制效果。

Automation rapid fire artillerylinking with fire control system can shoot mass ammunition and bullet in short time. Theartillery uses electron time fuze to control explosion of the ammunition and form a bullet wallin front of the attacking target to block the missile. Nowadays, applying this kind ofautomation artillery is the development direction to counterattack armed forces helicopter andshort-range counterattacking missile.

采用与火控系统相连的自动化速射炮，在短时间内发射出大量的弹药或子弹药，并通过电子时间引信控制弹药的起爆，在来袭目标前形成一&弹幕&墙来拦击导弹，是目前反武装直升机和近程反导的发展方向。

Isoniazid 100mg+Amikacin 200mg+Dexamethasone 2 mg were insufflated to the focus before and after operation. KTP laser therapy periods were 2 to 5 weeks, once weekly, therapy times were 1 to 2 seconds times 10 to 20, and intermittent times were 2 to 3 seconds, therapy current was 10A+.

KTP激光治疗2~5周，每周1次，每次治疗时间1、2s×10~20s，间歇2、3s，治疗电流10A+，导光纤维0.4mm或0.6mm，脉搏血氧计监视患者术前、术中、术后的心率和血氧饱和度的变化。

It also showed that the main influencing parameters of the uniformity of LGP front, middle and rear regions are the angle and interspacing of incidence side V-Cut.

导光板均齐度最主要影响参数前区域为底部V-Cut角度、其次为底部V-Cut间隔；中区域为底部V-Cut间隔、其次为入光侧V-Cut角度；后区域为入光侧V-Cut间隔、其次为底部V-Cut间隔。

The cash will be spent on pupil support staff who work on specific programmes outside of formal teaching to help the most disruptive pupils improve their behaviour as well as more teaching assistants to help teachers in the classroom and give more one-on-one support to unruly chil-dren.

这样的行动计划导因於去年10月一项针对老师的调查，其中显示出有4分之3的老师曾在调查的前一周中，经历过来自学生的恶言相向、67％曾遭口语暴力，大约有5分之1（17％）甚至遭受肢体上的暴力。

The results suggest that the enhancement of GABA-activated currents by OT may suppress primary sensory transmission by potentiating pre-synaptic inhibition of GABA.

以上结果提示：OT受体激活后可能通过相应的胞内转导机制增强GABA激活电流，从而在初级感觉神经元水平加强GABA的突触前抑制作用而减弱感觉信息的传递。

The cut tubing shall be reamed before connection to a fitting.

应在连接至管件前将切割的导压管进行铰孔。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
