Fine carbides precipitated from ferrite in 16-6 Cr-Mo, 16-2.5-6 Cr-Ni-Mo, and 16-5-6 Cr-Ni-Mo steels in the early stages of ageing are metastable, during prolonged heating they redissolve and are gradually replaced by χ-phase. Some residual carbides serve as the nuclei of the growing χ-phase. The structure of quenched 16-15-6 Cr-Ni-Mo steel is austenitic, during subsequent heating only M_6C and M_(23)C_6 mixed carbides are precipitated.

在16-6Cr-Mo、16-2.5-6及16-5-6Cr-Ni-Mo不锈钢中，从铁素体内沉淀出来的细小碳化物是一种过渡组织，在x相的成核与长大过程中，它们将不断地进行溶解。16-15-6 Cr-Ni-Mo不锈钢属奥氏体型，在不同温度进行固溶处理，奥氏体都很稳定，在随后的恒温处理过程中，只有碳化物从奥氏体内析出。

Egr-1 mRNA and Egr-1 protein hadn't been found in the normal vein. The expressions of Egr-1 mRNA and Egr-1 protein had biphasic changes. By reverse transcription-PCR and in situ hybridization, we found that the level of Egr-1 mRNA rose at 1 hour after graft, the expression of Egr-1 mRNA was (35±7)%. Decline at hour 6, 24 and day 3, the positive rates of Egr-1 mRNA were (8±2)%,(8±6)% and (8±4)% respectively. Reincrease at day 7, a peak at day 28, the positive rate of Egr-1 mRNA was (45±6)%(compared with other phase, P＜0.01). At day 42, the expression of Egr-1 mRNA declined again. Immunohistochemical staining and Western blot revealed Egr-1 protein had expressed at hour 2 early phase, the expression of Egr-1 protein was (30±5)%, and until to hour 6. The level of Egr-1 protein was decrease at hour 24 and day 3, the positive rates were (7±3)% and (7±8)% respectively.

结果 自体静脉移植后，Egr-1 mRNA和Egr-1蛋白的表达呈双相变化，即移植后1 h， Egr-1 mRNA表达迅速升高，阳性率为（35±7）%，6 h、24 h及3 d时下降到较低水平，阳性率分别为（8±2）%、（8±6）%和（8±4）％，7 d时又再升高，28 d时达高峰，阳性率为（45±6）%，此与其余各时点比较差异均有统计学意义（P＜0.01），42 d时，Egr-1 mRNA的表达再次下降；移植早期（2 h）即有Egr-1蛋白的表达，阳性率为（30±5）%，并持续至6 h，24 h～3 d表达下降到较低水平，阳性率分别为（7±3）%和（7±8）%，7 d时又再升高，至移植后28 d，Egr-1蛋白的表达阳性率达到高峰，为（40±9）%，此与其余各时点比较差异有统计学意义（P＜0.01）。

According to review the history of western higher education, we find that middle age's university is content to the need of social specialty;renaissant university is content to the aspiration of humanism;in science education phase, university is content to pursue pure knowledge;in technical education phase, university is content to the development of society and country.

通过对西方高等教育的历史考察，我们发现：中世纪大学主要是满足当时的社会专业需求而存在；文艺复兴时期的大学为了人文主义的抱负而存在；科学教育阶段的大学是为纯知识的追求而存在；技术教育阶段的大学为社会和国家的发展而存在。

Whereas in glial cells, SP-induced calcium transients had fast kinetics with a rapid rise phase (0.99±0.25/s) and an exponential decaying phase (t〓=12. 6 s). In addition, the spike-like SP response had a steady duration and a distinct delay. SP receptors desensitized completely within a few minutes, and no resensitization was observed within an hour.

而且，SP在胶质细胞上引起的这种峰样〓变化具有稳定的时程，与给药开始时间之间有一个显著的延迟，并极易脱敏，几分钟内就可完全脱敏，1小时内没有发现复敏。

And most osteocytes were in resorptive phase, few cells in degenerative phase.

骨细胞多数表现为吸收相，也有一些呈退变相。

The result shows that the purification efficiencies of ammonia-nitrogen and ortho-phosphate by immobilized algae in a stationary phase are higher than that in an exponential phase; the starvation treatment increases the removing rates of ammonia-nitrogen and ortho-phosphate, cells of Scenedesmus starved for 48 hours can obtain higher NF4(superscript +)-N and PO(superscript 3- subscript 4)-P removal efficiencies than starved for 48, 72, 24 and 0 hours respectively.

结果表明：静止初期藻细胞对NH4-N和PO(上标 3-下标 4)-P去除率比指数末期高，处理5d后，静止初期细胞对NH4-N和PO(上标 3-下标 4)-P的去除率分别为76.7%及91.7%，指数末期细胞氮、磷的去除率分别为75.4%和88.7%；饥饿处理可明显提高藻细胞对NH4-N和PO(上标 3-下标 4)-P的去除效率，藻细胞饥饿时间对NH4-N和PO(上标 3-下标 4)-P去除率的影响大小依次为48h，72h，24h，0h。

The evidence of sustained clinical effect from Week 52 to Week 208 in seropositive patients were treated with belimumab from initiation of the Phase 2 study included an increase from 46% at Week 52 to 57% at Week 208 in the percentage achieving the patient response rate selected as the Phase 3 primary efficacy endpoint.

In consideration of the in-pulse phase modulation and Doppler frequency rate-of-change's subtleness, a fast and accurate algorithm is proposed. The influence to parameter estimation with phase modulation is dismissed by time domain correlation between neighboring pulses. Signal noise ratio is increased by frequency domain accumulation.

该文针对信号脉内相位调制和多普勒频率变化率信息非常微弱的特点，提出了一种快速高精度估计算法，通过相邻脉冲间的时域相关消除了相位调制对参数估计的影响，频域积累增强了信噪比，利用脉冲间的相参特性进行频谱相关消除了相位模糊，并放大了多普勒频率变化率信息。

Its bad outcome is closely related to the rebleeding in the superacute phase.The therapeutic effect of traditional therapy for ICH in superacute phase by operation is disputable,while,the recent clinical test showed that treatment for ICH by using recombinant activated factor Ⅶ can obviously inhibit the rebleeding of intracerebral hemorrhage,and then lower the case fatality,promote its prognosis with better efficacy and safety.It is under the further studying.
