查询词典 comparatively

Using the models, the author has also calculated the vibration response to high speed railway vehicles of three types travelling over simply-supported beam bridges with various span lengths respectively. Based on the analysis of the computation results, the concept of resonance velocity of a bridge under a high speed running vehicle is present, and it is pointed out that comparatively great vibration of bridges on high speed railways is caused by bridge resonance resulted from the static force pulsating. In a vehiclebridge coupling vibration system, the damping constant of the axle spring is the main factor affecting the response variable of bridge velocity resonance, and the influence of track irregularity on bridge vibration on high speed railways is rather smaller.

利用所建立的计算模型，计算了三种形式的高速铁路车辆通过各种跨度简支梁桥结构时的振动响应，对所得到的计算结果进行了详细的分析，提出了高速行车下桥梁共振速度的概念并指出高速铁路桥梁产生较大振动的原因是静力脉动引起桥梁共振造成的；通过研究车—桥耦合振动系统方程的参数后指出，在车—桥耦合振动系统中，车辆—系阻尼的大小是影响桥梁速度共振时响应大小的主要因素，轨道不平顺对高速铁路桥梁振动的影响较小。

Diamond that are blue in both daylight and incandescent light are rare, although fluorescence stones that show a blue colour in daylight are comparatively common.

In other cases, the detection results of the WLE chart and the WLC chart have narrow difference, but the implementation and computation of the WLE chart is comparatively simpler.

通过与WLC图的比较，可以看出WLE图在均值和方差漂移比较小时要优于WLC图，其他情况下的检测效果与WLC图相差不大，而且操作相对于WLC图要更简便，计算要更简洁。

The arrangement of the 18 DP screwcutting changewheels (usefully identical in tooth form to those on Boxford and South Bend 9-inch lathes but fitted to comparatively small-diameter studs) was also rather clever: the headstock spindle, being driven from its left-hand end, was clear in the middle and advantage was taken of this to mount on it a simple but ingeniously contrived dog clutch to the first part of the changewheel drive; this device allowed threads, even ones of an odd-number, to be engaged and disengaged without error.

安排18压screwcutting changewheels （牙齿有益相同形式向那些对Boxford和南本德9英寸车床，但安装相对小直径螺栓）也相当聪明：主轴的启闭，被赶出其左手为此，显然在中东和优势是本挂载它简单但巧妙人为狗离合器的第一部分的changewheel驱动；这个装置允许线程，即便是那些一个奇数号码，参与和脱离接触没有错误。

The results of SS investigating indicated that the SS protein expression in leaf at seedling stage was high comparatively, when at jointing and heading stage, SS expression was low in leaves and stems, along with sorghum development, since flowering stage, SS expression increased sharply, decreased at dough stage.

2对SS表达检测结果表明，甜高粱苗期叶片中SS蛋白质表达量较高，拔节、抽穗期叶片和茎中SS蛋白质表达量较低，随着高粱的生长发育，开花以后叶片和茎中SS的表达量普遍升高，腊熟期略有下降。

We carry on studying and designing of drainage pipe imaging testing system comparatively lately. Therefore, it is epoch-making and meaningful that I study the drainage pipe ultrasonic imaging testing system for our country"s online ultrasonic imaging testing system. And it is very much meaningful that we improve our country"s drainage pipe level.

由于我们国家对排水管道成像检测的研究起步比较晚，所以本课题研究的排水管道超声波成像检测系统对我们国家排水管道在线成像检测具有非常重要的意义，同时对提高我国的排水管道检测水平，也具有十分重要的意义。

Conclusin: the model is comparatively stable by dosage of 10mL/kg and weight and injecting earthnut oil mixed with CCL4 (0.12%) through celiac after 13h.

以10mL/kg的剂量按体重腹腔注射CCL4(0.12%)在13h后检测的模型组较稳定。
