Objective: Ultrasound is considered as an alternative enedrgy for post-myocardial infarction ventricular tachycardia due to its good penetration through tissues. This study was designed to observe the effects of acoustic power, duration, repetitive ablations, tissue-transducer interface temperature and different sites of the ultrasound ablation in vitro.

使用1.8 MHz超声，分别对①离体犬心肌标本：a采用不同的声功率、时间、次数进行消融，部分标本在消融测量换能器—组织间温度；b采用相同频率和声功率消融左、右心室肌；c 采用与组织接触和不直接接触的两种超声换能器消融；标本均以甲醛固定1～2周后测量损伤灶深度及体积。

UCLH ICT director James Thomas said: From fixed line extensions to BlackBerry devices, pagers for on-call remote staff and bleepers for medical consultants, downtime is not an option.

UCLH信息和通信技术主任詹姆斯托马斯说：从固定线延线，以BlackBerry设备，寻呼机的召唤远程工作人员和bleepers的医疗顾问，停机时间是不是一种选择。

Second is studying the traumatic condition changes in a choosey pressure at different post-PT phases. Moreover, we detected model PLA_2 activity, express of PLA_2 subtype mRNA by fluorescent quantitative RT-PCR technique, protein express and site by Western blot and IHC at different post-PT phases. At last, we studied the PLA_2 inhibited effects and model protection of Variabilin in vivo.

研究在不同压强的外力作用下，模型指定时相点的一般情况和存活率、大体、光镜及电镜下胰腺组织的病理变化和常规酶学变化，得到稳定建模致伤压强；然后，固定致伤压强，研究胰腺创伤后不同时相点的伤情变化(包括一般情况、胰腺组织的病理变化、AMS和LPS活性变化、血常规、血生化、胰腺细胞凋亡以及胰腺组织细胞生长周期变化情况)；再次，采用3H-花生四烯酸标记大肠杆菌膜作为底物的方法检测大鼠胰腺创伤后不同时相点的PLA_2活性，利用荧光定量RT-PCR技术检测其亚型mRNA的表达，利用Western blot和IHC技术检测其蛋白表达量和蛋白组织定位；最后，将Variabilin体内应用于急性胰腺创伤大鼠模型，研究其对模型的保护作用和对PLA_2的抑制效应。

This requires an adjustment to the movements of the various heddles unless they can all exist in a plane at a fixed distance from the fell of the cloth.

如果所有综框不能处于与织口有一个固定距离的平面上，就需要对各综框的动程进行调节。

In comparison with there Infinites, all finites are equal ,and I see no reason for fixing our imagination on one more than on another.

和这些无限比较起来，所有的有限都是相同的，我找不到理由把想象力固定在某种而非他种有限上。

Police are wary of itinerants who cannot be traced to a recognized camp boundary or to four walls.

警察则对那些查不出有他们的固定营地或居有四壁的旅游者保持警惕。

Police are wary of itinerants who cannot be traced to a recognized camp boundary or to four walls.

警察则对那些查不出有固定营地或住处的游荡者保持警惕。但最重要的或许是露营者自己

With an assist from Lunk and Rand, he had managed to commandeer and make serviceable an anni-disc-ravaged Beta, only to find that the VT was not much good outside the envelope and that the Ark Angel had removed herself to stationary orbit over the Southlands.

通过伦克和兰德的协助，他找到并修复起用了一架贝塔战机，却只发现变形战机实际上不怎样，而且大天使号已经移动到南大陆上空的固定轨道了。

The computationresults show that for a organ-pipe nozzle with a given configuration size, the nondimensional axial velocity attenuates slower with the increase in stand-distance, and the nondimensional axial velocity attenuation pattern remains the same, and the nondimensional axial velocity along the jet centerline attenuates slower with the increase in distance between the nozzleexit and the impinging plate.

计算结果还表明：对给定结构尺寸的风琴管喷嘴，随着喷距的增加，沿径向的无因次轴向速度衰减变慢、沿径向无因次轴向速度衰减规律不随喷速的变化而变化；无因次轴心速度的衰减规律随着喷嘴出口到井底间距离的增大，射流轴心速度衰减变慢，但其变化幅度不大；在固定靶距情况下，无因次轴心速度衰减规律不随喷速的变化而变化。

Rowing is different from the athletes for moving forward while canoes used by paddle in the boat was not fixed.

不同于赛艇的是，运动员面向前进方向，同时皮划艇所使用的划桨并不固定在船身上。
