结果表明,腔体静止时,射流速度沿腔体中心轴对称分布,腔体中心轴上的速度最大,两侧流速逐渐减小,近壁处为零;腔体转动时,在哥氏力的作用下,射流中心发生偏转,流场相对于腔体中心轴不再对称分布,腔体中各点处的流速分布随角速度而变化,压电射流角速度传感器利用这一特性敏感角速度。

And their sum of the endangium and the tunica media accretived significantly. Contrasted with the model control group, the luminal area accretived significantly. Its restenosis degree of the carotid and the sum of the endangium and the tunica media decreased.

结果 中药组、模型对照组与假手术组相比,管腔狭窄程度明显加重,内膜与中膜面积之和明显增大:与模型组相比,中药组在2周、4周时管腔面积明显增大、管腔的狭窄程度、内膜与中膜面积之和显著降低,在1周、2周时PDGF-B的mRNA表达水平明显增高。

On the basis of our series and the findings of Yapar et al, the sonographic features of pelvic TB may be categorized as wet type or dry type as follows. The wet type, found in 12 (75%) of 16 patients, is characterized by incompletely septated ascites, particulate ascites, loculated fluid (although clear ascites can also be commonly associated with tuberculous peritonitis ), a thickened peritoneum or omentum, and an adnexal mass, mimicking ovarian cancer; the dry type, found in a small number of cases, is characterized primarily by adnexal masses, adhesions, and loculated fluid, mimicking tubo-ovarian abscesses or complexes.

根据咱们和Yapar等人的发明,骨盆内部空腔TB的超声特征可以分为湿型或干型。16例病人中发明12例湿型TB,其特点是水臌内存在不完全的分隔、光点和多房性积液(尽管清亮的水臌通常也能归并结石性腹膜炎),和腹膜或网膜增厚和容易误诊成卵巢癌的附件团块;少量的病例呈干型TB,其特点主要是附件团块、粘连和多房性积液,象是输卵管-卵巢脓肿或复合体。

Here, we show that DEG5 and DEG8 form a hexamer in the thylakoid lumen and that recombinant DEG8 is proteolytically active toward both a model substrate and photodamaged D1 protein of photosystem II , producing 16-kD N-terminal and 18-kD C-terminal fragments.

我们研究发现在类囊体膜腔侧的DEG5和DEG8形成6聚体,重组的DEG8对于模式底物和光破坏了的光系统Ⅱ中的D1蛋白质都有蛋白酶解活性,可以将D1蛋白质剪切成N-末端16kD和C-末端18kD的片段。

Based on the ring-shaped laser-diode array side-pumped Nd:YLF high gain amplifier and the conventional plan-concave resonator, a simple structure single-longitudinal-mode single-pulse Q-switched oscillator is demonstrated by taking advantages of mode-selecting property of passive Q-switches (Cr4+:YAG crystal) and etalons (formed by two end of uncoated Nd:YLF rod).

以激光二极管环形阵列侧面抽运Nd:YLF棒高增益放大器模块为基础,在经典的平凹驻波腔中加入一片Cr4+:YAG晶体作为被动Q开关,利用被动Q开关本身所具有的振荡选模功能以及两端不镀膜的Nd:YLF棒所具有的标准具效应,简便地实现了稳定的单脉冲、单纵模调Q输出。

In this paper, preliminary FDS fire chamber to simulate the flue gas generated through the corridor adjacent to the room near the migration laws, an analysis of indoor air flow field and the movement of smoke layer, and through the simulation of fire scenes, in a simple form of visual dynamic display of the entire process of fire, in the simulation process to obtain more accurate fire-related parameters such as temperature distribution, gas flow and heat radiation, and analysis of simulation results through the fire chamber of the flue gas migration characteristics, results showed that the chamber in the absence of fire smoke control measures, the process of the spread of smoke filled the first chamber is at the top, with the passage of time, the proliferation of slowly downward until the entire chamber is full, and then through the corridor smoke quickly spread to the nearby chamber.

本文运用FDS初步模拟了腔室火灾产生的烟气通过毗邻的走廊向附近房间迁移的规律,分析了室内空气流场和烟气层运动状况,并通过对火灾场景的模拟,以简单直观的形式动态显示出火灾发生的全过程,在模拟过程中获得较准确的火灾相关参数,如温度场分布,烟气流动及热辐射等,并通过模拟结果分析腔室火灾的烟气迁移特性,结果表明着火腔室在无防排烟措施的情况下,烟气扩散的过程是首先充满腔室顶部,随着时间的推移,慢慢向下扩散,直至将整个腔室充满,然后烟气通过走廊快速向附近腔室蔓延。
