血必净在急性有机磷农药中毒中的应用

目的观察血必净注射液在治疗急性有机磷农药中毒时的疗效。方法将82例急性有机磷农药中毒患者随机分为血必净治疗组（40例）与对照组（42例）,在正规使用阿托品及胆碱酯酶复能剂治疗的基础上,治疗组加用血必净100ml静脉点滴,每天一次,共3天,50ml静脉点滴,每天一次,共4天,总疗程一周。观察治疗过程中两组间全血胆碱酯酶及C反应蛋白差别,统计平均住院时间及死亡率。结果治疗前后,血必净治疗组及对照组的全血胆碱酯酶均有恢复,且治疗组较对照组恢复速度快（P〈O．05）。在C反应蛋白水平治疗后第3、4天数值较前均有所改善（P〈0．05）,治疗组改善更著（P〈O．05）。治疗组平均住院时间明显少于对照组（P〈O．05）。结论血必净注射液能有效促进血胆碱酯酶恢复,较好调控机体炎症反应过程,改善SIRS症状,缩短住院时间,取得满意的疗效。     

酶法制备米渣可溶性蛋白粉

对米渣浓缩蛋白进行复合蛋白酶和风味蛋白酶联合酶解试验,在单因素试验基础上通过正交试验优化酶解条件,所得水解液米渣蛋白提取率达到57.81%。对上述水解液进行了二次风味蛋白酶水解试验。米渣蛋白的提取率可以达到63.6%。将酶解产物冷冻干燥即得蛋白含量为84.62%的可溶性米渣蛋白粉。     

饮用水放射性测定中水样蒸发浓缩方式对残渣量的影响

经对比实验，分析在饮用水放射性活度测定中，同一水样以不同蒸发浓缩方式制得不同残渣量的原因，得出控制水温及蒸制体积是制取准确残渣量的前提，从而在水样蒸发浓缩环节减少对放射性活度测定结果准确度的影响。     

Theorema aureum — 2

In the first part of this article, we had introduced the notion of quadratic reciprocity and dwelt briefly on its history, which goes back all the way to the work of Fermat. Then we discussed the Law of Quadratic Reciprocity (‘QRL’), which Gauss named Theorema Aureum. Following this, we gave a not too well known proof of the QRL, due to G Rousseau. Now we give two more proofs of the QRL, drawing respectively from ideas in linear algebra and field extensions; they too are not very well known.

His interest lies in expanding the existing applied paradigm of mathematics from stock market to unchartered subjects such as sociometrics.     

生物农药能否取代化学农药

近年来，生物农药被寄予厚望，希图用它来代替化学农药．生物农药并非都是无毒无公害，我们应辩证地看待化学农药．

Hardware architecture for RSA cryptography based on residue number system

A parallel architecture for efficient hardware implementation of Rivest Shamir Adleman(RSA) cryptography is proposed.Residue number system(RNS) is introduced to realize high parallelism,thus all the elements under the same base are independent of each other and can be computed in parallel.Moreover,a simple and fast base transformation is used to achieve RNS Montgomery modular multiplication algorithm,which facilitates hardware implementation.Based on transport triggered architecture(TTA),the proposed architecture is designed to evaluate the performance and feasibility of the algorithm.With these optimizations,a decryption rate of 106 kbps can be achieved for 1 024-b RSA at the frequency of 100 MHz.
