摘要：新型电力系统建设背景下，分布式光伏爆发增长、柔性负荷大量涌现的配电领域正在经历深刻变革。配网可调节资源挖掘利用既能解决配网分布式新能源增加导致的反向重过载、电压越限等问题，还有助于缓解主网运行压力。首先，提炼了配网可调节资源利用技术存在的痛点问题，指出配网电力系统运营模式转型是解决问题的基础所在。回顾分析了集中式、分散式等国内外运营模式与微网、虚拟电厂等多种配电系统形式在解决配网运行问题方面存在的优缺点。提出适应中国大电网集中调度模式的配网集中-分布式协同自治调控的运行新范式，依托台区智能终端，通过“内部自治、相邻互济、整体协同”的协同自治调控模式，实现配调-台区-终端分层分级优化调控，为新型电力系统提供全新的技术路径。最后，归纳了协同自治调控运营模式下的配网关键技术和未来研究方向。

电热综合能源系统中的热力管网由于较强的热惯性而具备被动储热能力，可以提高电力系统的调节能力，为大规模可再生能源并网消纳提供空间。利用热力管网储能的方法可在不增加额外设备与投资的前提下，仅通过电力、热力系统的协调优化，达到平抑可再生能源波动性与间歇性、提高可再生能源使用率的目标。该方法已成为目前较具潜力的灵活性提升手段之一，逐渐受到国内外广泛关注。热力系统本身具有多变量、非线性、时延性等特点，且热力管网运行调节独立于电力系统调度之外，导致在刻画评估热力管网所具备的调节能力时，面临电热系统动态建模难以兼容、异质能源系统运行机制难以协调等瓶颈。研究围绕热力管网动态特性建模及电热协调优化等方面，对利用热力管网热惯性提升电热综合能源系统调节能力的研究方法展开回顾：比较分析了节点法、元素法、集总参数法、等效热电路法及能路法等动态建模方法的优劣，剖析了电力系统与热力管网协调运行研究中的关键要素，并针对进一步研究方向提出了几点建议。

将用户侧电、热、气等多种形式能源集成构建微能源系统，能够综合考虑多能流的转换、存储与传输过程中的互补特性，有利于提升系统的整体能源利用效率。然而，系统中不同形式能量的物理属性和传输特性差异较大，现有模型在研究多能流的传输和转换过程时，难以完整考虑热量传输约束及其对能量转换的影响。针对微能源系统中的综合能量管理问题，构建了热力系统中换热器的非线性传热模型，并考虑了热量传输对能量转换效率的影响。同时，结合光伏电池、储能电池、热泵、燃气锅炉、太阳能集热器及相变储热装置建立了微能源系统中能量传输与转换的整体模型，并以系统投资与运行总成本最小为目标构建了优化模型，提出了一种以混合整数线性优化为基础的分层迭代优化策略，通过对系统进行优化设计，研究了热量传输、转换与存储过程间的相互影响。对比发现：未考虑热量传输对热泵和太阳能集热器效率的影响时，太阳能集热器总出力为考虑热量输传输影响的80.2%，储热装置最佳容量仅为考虑热量输传输影响的48.9%。

The feed utilization rate of straw resources in China is low, because of the low crude protein content and high lignocellulose content of straw, which hinder the degradation of nutrients of straw by rumen microorganisms, so direct feeding cannot meet the nutritional needs of beef cattle. According to the content of crude protein, neutral detergent fiber, and acid detergent fiber in different harvest periods of straw in different regions, the optimal combination technology can effectively improve the palatability and nutrient structure of straw, and increase the utilization rate of straw feed, which is of great significance to solve the shortage of high-quality roughage and feed utilization of straw resources in China. This paper introduced the effects of optimized combination technology on gas content, microbial protein, fermentation parameters, and nutrient level of straw in vitro fermentation, and expounded the principle of optimized combination technology and its effects on growth performance, nutrient apparent digestibility, rumen fermentation, microflora, and breeding efficiency of beef cattle, in order to improve the rational utilization of straw resources for feed. It provides reference for the development and utilization of straw optimization combination technology in beef cattle production. [ABSTRACT FROM AUTHOR]

我國智慧財產民事訴訟中，以往囿於「公、私法訴訟二元制」之體系設計，被告即便認為原告所主張之智慧財產權有無效的理由，亦僅能循行政救濟的途徑主張，並無法直接於民事訴訟中直接提起智慧財產權無效抗辯，造成民事訴訟程序之延滯等不便。我國預計於2007 年間設立智慧財產法院，而該法院之設立對於我國智慧財產案件之爭訟將產生巨大而直接之影響，而攸關該法院成敗之主要關鍵⎯⎯「智慧財產法院組織法」及「智慧財產案件審理法」等二法案，業已送立法院進行審查。其中「智慧財產案件審理法」已 於2007 年1 月9 日經立法院三讀通過，「智慧財產法院組織法」亦已於2007 年3 月5 日經立法院三讀通過。「智慧財產案件審理法」中一項劃時代的變革，即是在第16 條第1 項規定：「當事人主張或抗辯智慧財產權有應撤銷、廢止之原因者，法院應就其主張或抗辯有無理由自為判斷」，易言之，該法條規定將直接改變目前我國「公、私法訴訟二元制」的現狀，對於專利訴訟當事人間自產生重大之影響，然依據該法案之規定，是否確能達到立法者之目的？以及是否需要有其他配套制度？本文將介紹我國智慧財產訴訟中 專利權無效抗辯相關制度沿革，並嘗試提供分析意見，同時就目前各國相關專利訴訟制度之設計，提供分析及建議。 In the past, the defendant of intellectual property (IP) litigation cannot raise the defense of patent invalidity in the civil litigation. The defendant can only file an invalidity action against the IP at issue. Such judicial system design delays the proceeding of the civil litigation of the IP infringement. The IP Court is proposed to be established in 2007. The establishment of the IP Court will change the current court proceeding of the intellectual property litigations tremendously. The core structure of establishment of IP Court is based on the “IP Court Organic Law” and “IP Trial Law.” The IP Trial Law has been passed by the Legislative Yuan on January 9, 2007 and the IP Court Organic Law has been passed by the Legislative Yuan on March 5, 2007. Paragraph 1, Article 16 of the IP Trial Law states that “the Court shall determination the intellectual property invalid defense raised by the defendant.” This Article will change the dual approaches of the public law and the private law in our current legal system and will create great impacts on both parties of the intellectual property litigation. This report would like to introduce and analyze this new court proceeding design and provide useful analysis and suggestions with respect to this new development.

Microbial mineralization technology has a strong advantage in the solidification of shallow slope. This is an environmentally friendly and sustainable approach. A test bacterium Bacillus sphaeroides kp-22 was used to induce calcium carbonate precipitation to treat surface clay in Sichuan Province. Direct shear tests were conducted for the surface clay before and after mineralization using different concentration of bacterium to investigate the effect of microbial mineralization on the strength characteristics of clay. The results show that the shear strength of clay can be significantly improved by microbial mineralization. And the higher the concentration of the bacterial solution, the better the mineralization effect. With the increase in CaCl2 concentration, the strength of the sample first increases and then decreases, reaches the peak when the concentration of calcium chloride is 0.5 ~ 0.75 mol/L. In the range of urea concentration from 0 to 1.0 mol/L, the shear strength increases with the increasing urea concentration. When calcium chloride and urea are 0.75 mol/L and 1.0 mol/L respectively, and the absorbance value OD600 of bacterial solution is 1.2, the shear strength reaches a maximum and the mineralization efficiecy is the best. The empirical relations between shear strength parameters and their influence factors are established, and the internal mechanism of strength change is analyzed. [ABSTRACT FROM AUTHOR]

To study the changes of the expression of autophagy-related factors ULK1，Beclin1 and LC3 in chondrocytes of patients with osteoarthritis（OA）at middle and late stages，and the changes of autophagy after regula⁃ tion with rapamycin. Methods Five normal knee cartilage specimens（normal control group），ten mid-term OA carti⁃ lage specimens（mid-term OA group）and ten late OA cartilage specimens（late OA group）were collected. Chondrocytes were isolated and cultured in vitro. The mRNA and protein of ULK1，Beclin1 and LC3 were detected by real-time PCR and Western blotting，respectively. Chondrocytes in each group were added with serum-free medium（0 μmol /L rapamy⁃ cin）and 1，5 and 10 μmol /L rapamycin，respectively. After 54 h of treatment，the expression of autophagy-related fac⁃ tors in each group was detected according to the above method. Results Compared with the normal control group，the mRNA and protein expression of ULK1，Beclin1 and LC3 in the mid-term and late OA groups were decreased，and the de⁃ crease in the late OA group was more significant（all P < 0. 05）. Compared with the same group treated with 0 μmol /L ra⁃ pamycin，the mRNA and protein expression levels of ULK1，Beclin1 and LC3 in normal control group and mid-term OA group were increased after 5 and 10 μmol/L rapamycin treatment，and those in late OA group were increased after 10 μmol /L rapamycin treatment（all P<0. 05）. Molecules related to autophagy in the late OA group were lower than those in the mid-term OA group treated with the same concentration of rapamycin（all P<0. 05）. Conclusion The expression of autophagy related factors ULK1，Beclin1 and LC3 in patients with OA at mid-term and late stages decrease，and the decrease is more obvious in the late OA group. Rapamycin can increase the autophagy of normal and mid-term OA chondro⁃ cytes，but has no effect on not in late OA chondrocytes . [ABSTRACT FROM AUTHOR]

Objective: To investigate the effects of Atorvastatin Combined with tegrilol on inflammatory factors, blood lipids and adverse cardiac events in patients with unstable angina pectoris (UAP). Methods: 103 patients with coronary heart disease and UAP who were admitted to our hospital from February 2016 to February 2019 were selected, they were randomly divided into study group (n=52), control group (n=51). The control group was treated with Atorvastatin Combined with clopidogrel, and the study group was treated with Atorvastatin Combined with clopidogrel. The clinical efficacy, inflammatory factors, blood lipids, angina pectoris and adverse cardiac events were compared between the two groups. Results: The clinical efficacy of the study group was 88.46% (46/52) after one month of treatment, which was higher than 66.67% (34/51) of the control group (P<0.05). One month after treatment, total cholesterol (TC), hypersensitive C-reactive protein (hs-CRP), triglyceride (TG), interleukin-6 (IL-6), low density lipoprotein cholesterol (LDL-C), frequency of angina attack, tumor necrosis factor-α (TNF-α) and duration of angina pectoris in both groups decreased, while high density lipoprotein cholesterol (HDL-C) decreased. The TC, TG, LDL-C, IL-6, hs-CRP, TNF-α, angina attack times and duration of angina in the study group were lower than those in the control group one month after treatment, while HDL-C was higher than those in the control group (P<0.05). There was no significant difference in the incidence of adverse cardiac events between the two groups (P>0.05). Conclusion: Atorvastatin combined with Tiglillo is effective in the treatment of UAP patients with coronary heart disease. It can effectively improve the levels of inflammatory factors and blood lipids without increasing the incidence of adverse cardiac events, and has high clinical value. [ABSTRACT FROM AUTHOR]
