Fresh Products

Fresh products have a large loss in the process of cross-regional logistics. In this study, the cross-regional fresh cold chain logistics network was analyzed using GO-FLOW analysis method. First, the basic principle of GO-FLOW analysis method was introduced. Then, taking the cold chain logistics network of mangosteen as an example, the GO-FLOW diagram was established, the signal strength was calculated, and the logistics network was improved according to the analysis results. The results showed that the reliability of the logistics network was 0.842, among which the reliability loss in precooling, long-distance transportation and sales was the largest. After improving the logistics network according to the three links, the reliability of the logistics network rose to 0.958, increased by 5.53%, among which the long-distance transportation link increased by 9.03%. The analysis results verifies the feasibility of GO-FLOW analysis method in logistics network analysis and make some contributions to improve the efficiency of physical network and ensure food safety.

Diffraction Patterns

Computer programs are now available in various laboratories for the indexing and simulation of transmission electron diffraction patterns. Although these programs address themselves to the solution of various aspects of the indexing and simulation process, the ultimate goal is to perform real time diffraction pattern analysis directly off of the imaging screen of the transmission electron microscope. The program to be described in this paper represents one step prior to real time analysis. It involves the combination of two programs, described in an earlier paper(l), into a single program for use on an interactive basis with a minicomputer. In our case, the minicomputer is an INTERDATA 70 equipped with a Tektronix 4010-1 graphical display terminal and hard copy unit.A simplified flow diagram of the combined program, written in Fortran IV, is shown in Figure 1. It consists of two programs INDEX and TEDP which index and simulate electron diffraction patterns respectively. The user has the option of choosing either the indexing or simulating aspects of the combined program.
