Power factors related to the degree of power transmission and distribution lines and equipment supply,but also affects the power loss.This paper analyzes the impact of the main reasons for power factor,discussed the principle of the rational allocation of reactive compensation and the power factor of low voltage network and equipment,we can meet the purpose of saving energy and reducing losses.

A Controlled Clinical Trial of Citalopram and Citalopram Combined with Psychotherapy in the Treatment of Postpartum Depression

Zhongguo xinli weisheng zazhi (2005)

Qiu Chun

Objective:To compare the efficacy of citalopram alone and citalopram combined with psychotherapy in patients with postpartum depression. Methods:Fifty-eight women who met CCMD-3 criteria for postpartum depression were randomly assigned to 2 groups. Group A was treated with citalopram 20mg daily alone, group B with citalopram 20mg daily combined with psychotherapy, both for six weeks. Hamilton rating scale (HAMD) was evaluated at baseline and after 1, 2, 4 and 6 weeks of treatment. Results:HAMD scores were decreased with statistical significance since week 1 in group A and since week 2 in group B. At different time points the HAMD scores in group A were lower than those in group B with statistically significant difference. Conclusion: Citalopram combined with psychotherapy was more effective than citalopram alone in the treatment of postpartum depression.

Neural Network Based Multiple Criteria Decision Making

Journal of Beijing Institute of Technology (2000)

Qiu Chun

To solve the multiple criteria decision making problems, the multiattribute value function was extended based on the existence of the value function. A 3 layered BP neural network was used to construct the value function from the samples extracted from the multiple criteria decision making problems, then the calculated values of every plan were compared. The automation of multiple criteria decision making is implemented, the results agree with the results of the traditional algorithms and meet the Pareto optimal criterion.

A FREQUENCY DOMAIN METHOD FOR THE STACK OF SEISMIC DATA

Qiu Chun

The conventional stack method of seismic data gives quite good results when the errors of time corrections are small enough or the arrivals are near the same. However the stack effect is severely influenced if the time corrections are not undertaken completely. The amplitude and resolution of the stacked trace decrease, sometimes seriously due to the errors of time corrections. This paper proposes a frequency domain stack method that remains the advantage of conventional method and can eliminate the time errors automatically during stacking. Some examples indicate the good effect of the novel method.

Mozi' s Society Blueprint and Design Theories

Journal of Nanyang Teachers'College (2005)

Qiu Chun

Mozi daringly constructed a society blueprint of impartial caring universal lovefor common people, and his design theories correlated with this blueprint inseparably. In his theories, Mozi answered those questions respectively, such as design should serve for what kind of people; for what kind of society; and for what kind of future,etc. Mozi advocated the practicability of design,but his design theories are highly Utopian.

Solid-Phase Synthesis of Nanophase α-Fe_2O_3 Particle

Journal of Inorganic Materials (2001)

Qiu Chun

Nanophase α-Fe2O3 particles were systhesized by a solid-phase method. The prepared samples were characterized by XRD, Mossbauer spectroscopy and TEM. The results show that the prepared samples are α-Fe2O3. The particle sizes of the samples are about 20-40nm and their shapes are peanut-like.

Preparation of Polycrystalline Silicon Thin Films at Low Temperature by PEVCD

Chinese Journal of Liquid Crystals and Displays (2003)

Qiu Chun

PolySi films with large grains (100nm in diameter) were fabricated at relatively high deposition rate(～0.92nm/s) and low temperatures(≤400℃ ) by conventional PECVD system.In addition, it was found the grains' preferential orientation (220) is obvious. The films is obtained using SiF4 and H2 mixture as reaction gas source.When a little amount of SiH4 was added, the deposition rate was increased to almost 10 times. On the experiments we confirm that not the SiHn(n ≤3)but the SiFm Hn(m+n≤3) has contribution to polySi films growing at low temperatures.
