In order to reduce the negative effect of gross Al-rich inclusions on high aluminum steel, both thermodynamic calculations and designed deoxidization experiments were performed in condition of different silicon and aluminum deoxidization sequences. Thermodynamic calculations demonstrated that the complex inclusions with low melting point （harmless inclusions） are more favorable to be formed in condition that the melt was deoxidized using ferrosilicon first and then pure aluminum （Si/A1 deoxidization） than that deoxidized using pure aluminum first and then ferrosilicon （AI/Si deoxidization）. Al-rich inclusion decreases 83% from A1/Si deoxidization to Si/A1 deoxidization. The experimental results showed that the total quantity of inclusions decreases by 24% and the proportion of harmless inclusions is doubled when comparing Si/Al deoxidization with Al/Si deoxidization. The morphology of complex inclusion tends to be spherical, and the mean size is less than 5μm in condition of Si/Al deoxidization. The formation mechanism of harmless inclusions was discussed, and it is believed that the inclusions can be controlled reasonably in high aluminum steel using Si/Al deoxidization.

In downlink multi-user multi-input multi-output （MU-MIMO） system, not every user （user equipment （UE）） can calculate accurately signal to interference and noise ratio （SINR） without prior knowledge of the other users＇ precoding vector. To solve this problem, this article proposes a channel inversion precoding scheme by using the lower bound of S1NR and zero-forcing （ZF） algorithm. However, the SINR mismatch between lower bound SINR and actual SINR causes the inaccurateness of adaptive modulation and coding （AMC）. As a result, it causes degradation in performance. Simulation results show that channel inversion precoding provides lower throughput than that of single user multi-input multi-output （SU-MIMO） at high signal-to-noise ratio （SNR）（〉14 dB）, due to the SINR mismatch, although the sum-rate of channel inversion precoding is higher than that of SU-MIMO at full SNR regime.

OBJECTIVE： Even in secular societies, a small portion of patients find their spirituality to help cope with illness. But for the majority of patients, psychosocial and spiritual needs are neither addressed nor even considered a relevant factor by health care professionals. To measure such specific needs, the Spiritual Needs Questionnaire （SpNQ） was developed. The aim of this study was to validate the Chinese version of the SpNQ （SpNQ-Ch） and thus to measure psychosocial and spiritual needs of Chinese patients. METHODS： This was a cross-sectional study among 168 patients with chronic diseases who were recruited in the Changhai Hospital of Traditional Chinese Medicine, Shanghai, China using standardized questionnaires. We performed reliability and factor analyses, as well as analyses of variance, first order correlations and regression analyses. RESULTS： The 17-item SpNQ-Ch had a similar factorial structure as the original version with two main and three minor factors which accounted for 64% of variance, and internal consistency estimates （Cronbach＇s a） ranging from 0.51 to 0.81. Included were the 4-item scale Inner Peace Needs, the 5-item scale Giving/Generativity （with 2 sub-constructs, Praying and Sources）, and a Needs, the 5-item scale Religious Needs 3-item scale Reflection/Release Needs. In Chinese patients with cancer （63%）, pain affections （10%）, or other chronic conditions （23%）, the needs for Giving/Generativity （which refer to categories of Connectedness and Meaning） and Inner Peace Needs scored highest, while Religious Needs and the Reflection/Release Needs scored lower. CONCLUSION： The SpNQ-Ch is congruent with its primary version, and can be used in future studies with the mostly nonreligious patients from China. First findings indicate specific psychosocial and spiritual needs which should be addressed by health care professionals to support patients in their struggle with chronic illness in terms of psycho-emotional stabilization, finding hope and mean

等通道转角挤压应变计算为掌握挤压变形程度、衡量强烈变形效果、正确制定工艺规程、合理设计成形模具提供重要依据。目前国内外强烈塑性变形领域广泛使用Iwahashi Y于1996年提出的应变计算公式。经过分析,指出了该计算公式理论推导不严谨,关于切向速度间断对变形影响的分析有误,对运算过程中的近似处理不当,应变计算结果不正确,未能反映挤压变形的真实情况。根据强烈塑性变形特点,分析了挤压塑性变形区的流动规律,针对该公式存在的问题采取了改进措施,经过详细运算,建立了概念比较完整、理论比较严谨的新公式,并结合实例对两者进行了比较。实例计算结果证明了提出的新应变计算公式的有效性。
