大量实验表明，很多细胞在凋亡早期会出现胞质内Ca2+浓度迅速持续的升高，这种浓度升高来源于细胞外Ca2+的内流和胞内钙库的释放。

This contributes to the rigidity of the bearing and a precise radial guidance of the shaft. For special applications, full-complement cylindrical roller bearings are employed. The cylindrical roller bearing designs are shown in Figures 1.20 and 1.21.The designs of cylindrical roller bearings are distinguished by the arrangement of the lips. Design NU (Figure 1.21b) has two lips on the outer ring, the inner ring being lipless. In design N (Figure 1.21a), the inner ring has two lips, the outer ring has none. Cylindrical roller bearings of designs NU and N are applied as floating bearings because the rollers can freely shift on the lipless ring in the axial direction. Cylindrical roller bearings NJ (Figure 1.20) have two lips on the outer ring and one on the inner ring; they can take up axial forces in one direction. Design NUP (Figure 1.21d) is installed as a locating bearing to sustain frequently reversing axial forces.

这可以提高轴承的刚度，和主轴精密的径向引导，对于特别的运用，密排的圆柱滚子轴承被运用，圆柱轴承的图样在图。20和1.21展示圆柱滚子轴承图样由挡边的不知来区分，图样NU(图1.21b)在外圈有两个挡边，内圈无挡边，在图样N中内圈有两个挡边，外圈无挡边，图样NU和U所示的圆柱滚子轴承可制作浮动轴承因为滚子能够在轴向无挡边环上自由的移动，圆柱滚子轴承NG在外圈上有两个挡边，内圈上有一个，它们能够在某个方向上承受轴向力，图样NUP（图1.21d）被用来安装在一个保持经常扭转轴向力的固定轴承上。

To verify the accuracy of CFD simulations, experiments were carried out. The results of simulations with user defined function of the effects of impeller type and stirring rate on the velocity field were in good agreement with the output of particle image velocity. The oxygen mass transfer model can be used to predict the process of oxygen mass transfer in a vessel, and the logarithmical expression can successfully describe the relation between the oxygen concentration and the dissolution time.

结果表明，(1)采用Fluent软件并结合用户自定义方程(user defined function， UDF)能够很好地模拟出实际搅拌器内流场分布，模拟结果与采用粒子成像技术(particle image velocity， PIV)的实验测量结果相符；(2)采用氧气传质模型能预测氧气在搅拌器内的动态传质过程，同时氧气浓度与溶解时间的对数关系式能较好描述试验搅拌器内氧气动态传质过程；(3)在相同搅拌速度下，圆盘涡轮式搅拌器产生的湍流动能分布范围要大于桨式搅拌器产生的湍流动能，而且湍流动能分布更均匀，湍流强度更大。

Within 6 months, all 40 patients with cervical plates had fusions, and the cervical lordotic alignment was increased (2.51±6.75), and without plates and bolt loose or break. Of the 30 patients without plates the cervical lordotic alignment were decreased (1.33±3.43)(P.01), 2 patients had not fusions within 6 months (the fusion rate was 93.3%).

植骨融合率和颈椎生理曲度：植骨加钛板内固定组术后6个月内植骨融合率100%，颈椎生理曲度维持良好，较术前增加(2.51±6.75)°，无钢板和螺钉松动或断裂；单纯植骨组术后6个月内植骨融合率93.3%，颈椎生理曲度较术前减少(1.33±343)°，两组比较差异有显著比(P.01)， 2例术后3个月假关节形成。

Cannulated screw fixation for the treatment of 10 cases were associated with varying degrees of varus deformity of hip, loosening of internal fixation, of which three cases of malunion, nonunion of four cases, the late anti-concurrent three cases of intertrochanteric fracture.

空心钉内固定治疗10例均伴发不同程度的髋内翻畸形、内固定松动，其中畸形愈合3例，不愈合4例，后期并发反粗隆间骨折3例。

However, only one patient had relapse in the soft tissue two years later. The en bloc excision was performed again. Thus, the relapse ratio was 11%. According to Mankin score, there was excellent (n=3), well (n=4), passable (n=1), and poor (n=1), thus the finess ratio was 80%.

所有患者骨内无复发，仅1例术后2年软组织内复发，并再次行软组织内肿瘤切除，复发率为11%。9例患者中按Mankin标准评定，优3例，良4例，可1例，差1例，优良率为80%。

With higher content of β-carotene. The length and width of perianth segment(inner 2 ring) were osculant, the former showed matroclinous inheritance, the latter showed patroclinal inheritance, so Liriodendron interspecific hybrids with bigger perianth segment could be selected by Liriodendron chinense?

杂交鹅掌楸内两轮花被片长度和宽度为双亲中间型，分别偏向母本和父本，用内两轮花被片较宽的鹅掌楸作母本，内两轮花被片较长的北美鹅掌楸作父本，有望选育出大花的杂交鹅掌楸个体。

Maxillary sinus puncture was performed on these patients both for sampling of sinus contents and irrigation of the diseased sinuses. Aspirate contents of the sinuses were collected for aerobic and anaerobic cultivation. 3 A prospective study of pediatric patients with community-acquired rhinosinusitis was conducted. Bacterial culture was performed on the specimens obtained from maxillary sinus by puncture and middle meatus by endoscopic sampling. The correlation and diagnostic usefulness of endoscopic middle meatal culture versus maxillary sinus puncture were determined.

我们搜集鼻咽癌放射线治疗后患有急性上颔窦炎的病人，以上颔窦穿刺搜集这些病患的鼻窦分泌物并冲洗其患病的鼻窦，收集到的鼻窦分泌物则送往实验室做细菌培养。3 我们执行前瞻性研究，收集患有社区感染鼻及鼻窦炎的儿童，这些病童会同时接受内视镜中鼻道培养与上颌窦穿刺培养，为了厘清儿童使用内视镜中鼻道培养的可信度，我们计算内视镜中鼻道培养与上颌窦穿刺培养结果的关联性与诊断测试。

Nestin-positive cells were in the mesenchyma of small intestine, none of which in the crypts. In mucosa of descending colon, Musashi-1-positive cells were mainly located between cell positions 1 and 4, and TERT-positivc cells 1 and 5. Oct-4-positive cells were diffusely distributed in the crypts and the mesenchyma. Nestin-positive cells were all in the mesenchyma, none in the crypts.

降结肠黏膜中Musashi-1和TERT阳性细胞分别主要在距隐窝底部1~4个和1~5个细胞的位置，Oct-4阳性细胞散在分布在腺体内和黏膜间质，Nestin阳性细胞分布黏膜间质内，腺体内无表达。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
