The development of forest biomass briquetting densification fuel, which has a high calorific value, can ease the energy shortage in China. But the molding technology is still at the primary stage with many questions unresolved, such as unequal distribution of resources, imperfect technology and an inadequate mechanism of market supply and demand. There are no consistent production and quality standards to refer to, which seriously hinder the industrialization of biomass molding technology. Hence, it is imperative to speed up the formulation of production standards of biomass briquetting densification fuel which not only conform to international standards, but are in accordance with national condi- tions in China. Drawing on the standards of biomass briquetting densification fuel in Europe, a standard system should be concerned with raw material collection, transport and storage of the end products, terminology, denomination and classification of molding equipment, as well as with technical conditions, testing methods, safety and environmental protection. The establishment of a stan- dard system is useful for the development of a healthy, orderly and sustainable biomass fuel industry.展开更多

Methods: cases were selected from January 2019 to December 2020. Case type: PICC catheter for tumor chemotherapy;Total cases: 82;Grouping method: random envelope method;Group: reference group and observation group;Number of groups: 41;Nursing methods: routine nursing and standardized nursing process of PICC;Comparative items: nursing satisfaction, complications and phlebitis. Results: the nursing satisfaction of the observation group and the reference group was 97.56% and 8.48% respectively, with significant difference (χ2 = 6.1157). The incidence of complications in the observation group and the reference group was 7.32% and 24.39% respectively, with significant difference (χ2 = 4.4794). The incidence of phlebitis in the observation group (grade 0: 73.17%, grade 1-2: 24.39%, grade 3-4: 2.44%) was lower than that in the reference group (grade 0: 34.15%, grade 1-2: 48.78%, grade 3-4: 17.07%). there was a significant difference between the groups (χ2 = 12.5550, 5.2564, 4.9865), with statistical significance (P < 0.05). Conclusion: the implementation of PICC standardized nursing process for tumor chemotherapy patients can improve the incidence of phlebitis and reduce complications. The nursing effect is significant, which is worthy of clinical reference.展开更多

Methods: Seventy-two patients with ST segment elevation myocardial infarction who were admitted to our hospital from January 2020 to December 2020 were selected as the main subjects of this study. They were divided into the control group/observation group. Among them, the control group received routine emergency care while the observation group received standardized emergency care procedures based on the routine emergency care measures, so as to compare the differences in the care procedures and patient care quality of the two patients during the emergency treatment. The difference was large, and the condition of the observation group was better. Finally, through the analysis of two groups of patients after treatment, and then investigate the family members and patients' satisfaction with care. The clinical results showed that the efficacy of 88.9% in the observation group was significantly superior to 66.7% in the control group, and the difference was statistically significant (P < 0.05). Conclusion: through analyzing the different nursing procedures of patients in two groups, it was found that the standardized emergency nursing procedures shortened the basic treatment time of patients and improved the success rate of rescue, providing a larger space for the treatment of patients, and the families were also satisfied with it.展开更多

However, most multivariate statistical process monitoring (MSPM) methods are based on the assumption that the process has only one nominal mode. When the process data contain different distributions, they may not function as well as in single mode processes. To address this issue, an improved partial least squares (IPLS) method was proposed for multimode process monitoring. By utilizing a novel local standardization strategy, the normal data in multiple modes could be centralized after being standardized and the fundamental assumption of partial least squares (PLS) could be valid again in multimode process. In this way, PLS method was extended to be suitable for not only single mode processes but also multimode processes. The efficiency of the proposed method was illustrated by comparing the monitoring results of PLS and IPLS in Tennessee Eastman(TE) process.展开更多

The modeling steps are arranged in dialog menu interface by VB 6.0, the shaft creator, that permits users input geometric feature based parameters explicitly, and the standardized processdata are reorganized in Excel files that can be invoked correspondingly in the modeling procedure. It is aimed that this process may supply a simple way for shaft rapid modeling and comprehensive discipline for engineering students in their professional design activities.展开更多

It is based on good analysis of the mechanical property of the yarn, weaving law of plain woven, and other factors. The method implements a woven fabric composite visual engineering modeling process standardization, and it gives five steps to calculate the key micro-structural parameters of the yarn including the cross-section and the trajectory of the central Line. On the basis, the digital model of a plain woven composite has been constructed. The experimental result shows that the forecast for the mechanical property of the model using finite-element simulation analysis is consistent with the actual value. The shape and the structure of the model are also consistent with the solid.展开更多
