工科背景高等院校开展统计教育的研究——以浙江科技学院为例

快速发展中的工科背景高等院校在统计教育上存在有待改进的地方。以浙江科技学院为例,为培养具有深厚统计学背景的应用型复合人才,在统计教育上作了一些探索：定位于浙江中小企业对统计知识的实际需求;选择注重实际应用的国外经典教材;在教学中注重学生的参与;在实践中培养学生运用统计学知识和统计工具如统计软件的能力。     

汽车照明防眩的新技术

文章介绍了一种新颖的汽车照明防眩技术，这是汽车前照灯的脉冲化照明所带来全新功能之一。通过利用高速频闪的脉冲氙灯，配合高速液晶电光开关制成的挡光板，让对方照明效果光透过，而挡去大部进入眼睛的外部眩光，从而达到防止眩光的目的。本文详细论述了这种新颖的防眩控制技术，并给出了在实用中多车交会时的处理方法。     

南京国民政府时期社会保险立法背景研究（1927-1937年）

当社会保险这种更为先进的保障方式在西方已经实行了四十多年时,对中国民众来说这还是一个陌生的名词,中国社会保障仍然以传统的社会救济为主。南京国民政府成立以后,在政府、民间以及国际劳工组织的推动下,对社会保险立法进行了初步的尝试。

A 60 GHz Medium Power Amplifier for Radio‐over‐Fiber System

We present the design and fabrication of a 60 GHz medium power amplifier monolithic microwave integrated circuit with excellent gain‐flatness for a 60 GHz radio‐over‐fiber system. The circuit has a 4‐stage structure using microstrip coupled lines instead of metal‐insulator‐metal capacitors for unconditional stability of the amplifier and yield enhancement. The gains of each stage of the amplifier are modified to provide broadband characteristics of input/output matching for the first and fourth stages and to achieve higher gains for the second and third stages to improve the gain‐flatness of the amplifier for wideband.     

Conformal Wavelet Finite-difference Time-domain Algorithm for Analysis of Milimeter Wave Attenuation on Coplanar Waveguide

Addressed is the calculation of millimeter wave attenuation on coplanar waveguide（CPW）. A novel conformal wavelet finite-difference time-domain（CWFDTD） algorithm is proposed with emphasis on its application in calculation of millimeter wave attenuation on CPW, which is the combination of conformal algorithm dealing with the deformed cell with Wavelet-FDTD using multi-resolution analysis（MRA）. Derived is the difference formulation for multi-resolution time domain（MRTD） based on Daubechies wavelets, and also given is the stability conditions for wavelet-FDTD algorithm. To validate its accuracy and efficiency, this novel method is applied to calculate the millimeter wave attenuation on lithium niobate CPW. Numerical results demonstrate that this new CWFDTD algorithm has the same accuracy with the conformal finite-difference timedomain（CFDTD） and conformal finite-difference time-domain based on alternating-direction implicit method （ADI-CFDTD）, but saves computational time and computer memory.

研究水电站工程所在区域及水库影响区天然地震背景水平,不仅可对水库诱发性地震的危险性进行前期评价, 而且可为蓄水后的诱发地震活动监测提供可靠的鉴别依据。通过分析向家坝水电工程所在的区域地震背景、构造特征、应力场及中强震震源机制特点,并结合相关地震监测数据和向家坝水库地震监测台网的地震监测数据,探讨了向家坝水库影响区及周边区域范围天然地震年频次、月频次、地震震级-频度关系及震源机制特征,可为向家坝水库蓄水后库区水库地震监测、预测及地震类型判识提供参考。     

The glutenin fraction of wheat protein: The importance of genetic background on its quantity and quality

The influence of high-molecular-weight glutenin subunits on the properties of the gel-protein fraction of glutenin proteins in wheat was determined on 20 varieties grown in the 1989 UK Recommended List trials. Both the presence of subunit 1 (chromosome 1A) and the 1B/1R rye translocation were shown to influence gel-protein weight and breakdown rate during mixing. The gel-protein tests were correlated with CBP (Chorleywood Bread Process) loaf volume, but they did not add anything to the correlation between Glu-1 score and loaf volume. Both gel-protein tests indicated that phenotypic variation could be almost as large as genotypic variation. Breakdown rate was able to detect the abnormal properties of Pastiche (weak) and Fresco (extra-strong) that were not observed using established quality tests such as the sodium dodecylsulphate sedimentation volume.
