Considering the many bright stars, nebulae, and star clusters in the region more familiar to skygazers, HD 189733 may not seem to be remarkable, but it is known to have at least one hot, jupiter-sized planet orbiting very close, with an impressively short period of 2.2 days.

在这个区域内，天空观测者们更为熟悉许多明亮的恒星，星云和星团，而HD189733可能不是那么显著，但是至少它是一颗炽热，木星大小的行星，轨道非常小，一个周期只需要2.2天时间。

Lastly, the paper studies the periodicity of the minimal strong components and the circularly dominating index.

并讨论了极小强支的周期与圈空指数的关系。

Women, in contrast, tend to hold more cyclically stable jobs and make up 75 per cent of the most insulated sectors of all: education and healthcare.

相比之下，女性往往占据着更具周期稳定性的职位，尤其是在教育和医疗这两个受经济影响最小的行业中，女性占据了75%的职位。

The linear complexity and minimal polynomials of new generalized cyclotomic se-quences of order two are determined. A scheme for hardware implementation isgiven.

在所有的此类序列中，线性复杂度最小值为(n -1)/2，可以达到最大值n，其中n 为奇数表示序列的周期。

Results Nicotinamide at 1-5 mg/ml induced apoptosis of GLC-82 cells in a dose-dependent manner, and group 4 mg/ml and group 5 mg/ml showed increased apoptosis than other groups. Distinct morphologic changes of cell apoptosis such as karyopyknosis and conglomeration were observed; Cell migration became slower as the dosage of Nicotinamide increased;Cells produced an arrested at G1 phase, accompanied by a reduction of cells transiting through S phase.

Result 1 Magnetic nanoparticles, magnetic nanoparticles modified with antisense oligodeoxynucleotide of human telomerase reverse transcriptase induced HL-60 tumor cells to apoptosis, we could see typical morphologic change of apoptosis cells: karyopyknosis, chromation"s condensing and aggregation in nuclear, forming crescent-shaped or annulus structures to lean on edge of cell nucleus"s membrane and posing apoptosis body by Atomic Force Microscope, Fluorescence microscope, transmission electron Microscope 2 There was a significant difference compared with control group(p.01), inhibition ratio had significant positive correlation with medication dosage and time ;during 0.8-8μM dosage amplitude, inhibition ratio accrescenced by dosages increasing. However, the inhibition ratio would decrease when dosage over 8-80μM.
