充分利用可再生能源是实现建筑节能减排的关键,其中建筑光伏受到社会普遍关注。本文针对夏热冬暖地区公共建筑,以某图书馆为例,建立了空调冷源及屋顶光伏系统TRNSYS仿真模型,对冷源系统能耗及光伏系统发电进行模拟。结果显示,在空调典型日,冷源系统运行功率需求与光伏发电供给两者具有较好的匹配性;在夏季空调运行时段,建筑光伏发电用于冷源系统的自给率达68%,碳排放量减少657.71 t/a。建筑光伏能被空调冷源有效消纳,减排效果显著。

Five nearly E-W-trending alkali-rich igneous rock belts are distributed from north to south in northern Xinjiang, and they are composed mainly of riebeckite, K-feldspar granite and high-K and medium-K calc-alkaline volcanic rocks and shoshonite. They were mainly emplaced or erupted between the Carboniferous and Permian. The compositions of Sr, Nd, Pb, and O isotopes imply that their principal resource materials are derived from the upper mantle or juvenile crust, indicating obvious continental growth in the Phanerozoic. The trace element association implies that their tectonic settings are within plate and volcanic arc for alkali-rich granites, and post-collisional are, late oceanic are and continental are for alkali-rich volcanic rocks. An archipelago model was suggested for the tectonic evolution in northern Xinjiang. It can be named the central-Asia-type orogeny, which is different from the so called circum-Pacific ocean-continent-type tectonics or the Alpine-Himalayan continent-continent-collisional orogeny.

Existing power grid fault diagnosis methods relyon manual experience to design diagnosis models, lack theability to extract fault knowledge, and are difficult to adaptto complex and changeable engineering sites. Considering thissituation, this paper proposes a power grid fault diagnosismethod based on a deep pyramid convolutional neural networkfor the alarm information set. This approach uses the deepfeature extraction ability of the network to extract fault featureknowledge from alarm information texts and achieve end-to-endfault classification and fault device identification. First, a deeppyramid convolutional neural network model for extracting theoverall characteristics of fault events is constructed to identifyfault types. Second, a deep pyramidal convolutional neuralnetwork model for alarm information text is constructed, thetext description characteristics associated with alarm informationtexts are extracted, the key information corresponding to faultsin the alarm information set is identified, and suspicious faultydevices are selected. Then, a fault device identification strategythat integrates fault-type and time sequence priorities is proposedto identify faulty devices. Finally, the actual fault cases and thefault cases generated by the simulation are studied, and theresults verify the effectiveness and practicability of the methodpresented in this paper.

We investigated the effects of bone marrow-derived mesenchymal stem cells （MSCs） transplantation on the recovery of neurological functions in rat＇s MCAO （middle cerebral artery occlusion） model and its mechanism. MSCs were isolated from bone marrow of male Sprague Dawley （SD） rats. Female adult SD rats were randomly assigned into 4 groups： sham-operated group, MCAO group, vehicle group and MCAO ＋ MSCs-treated group. MSCs were injected into the lateral ventricle of rats in the MSCs-treated group and the same volume of PBS was given to the vehicle group. The expressions of IL-10 and TNF-α were assayed by RT-PCR and ELISA detections at day 1 and 4 after MCAO. The infarction volume was measured by TTC-staining. All rats underwent behavioral tests before, as well as 1, 4, and 14 days after MCAO. MSCs significantly improved functional recovery compared with the control at day 14 after transplantation. Compared with the MCAO group and the vehicle group, the expression of IL-10 mRNA and its protein level in the MSCs group significantly upregulated. However, the expression of TNF-α at day 4 after MCAO in the MSCs group significantly decreased compared with that of the MCAO group and the vehicle group. As a result, transplantation with MSCs significantly decreased infarct volume at day 1 and 4. This study strongly suggested transplantation with MSCs could reduce neuronal injury post focal cerebral ischemia in rats partly by regulating the expressions of IL-10 and TNF-α in the brain.

对广州地区典型乔木的降温增湿进行了仿真研究,并以广州某校园住宅小区为模型进行了参数化研究:首先,基于实测数据对仿真平台进行了校准,以提升其仿真精度(如室外空气温度及湿度的最大均方根误差分别低至1.49°C和5.63%)。其次,为了全面揭示乔木树种的实体形态及其群落特征对城市微气候的影响机制,建立了芒果、蒲桃、小叶榄仁、细叶榕、腊肠树、白千层6种乔木仿真模型,采用ENVI-met对单株植物和植物群落的热环境调控作用进行了仿真。研究表明,叶面积指数、冠幅、树高对植被下方的地面温度和显热通量影响较大;植被在10 m高度以上时植被群落的降温效果较好,单株细叶榕的降温增湿效果最好;相比低矮植物,白千层植物群落的降温增湿效果更好,在中午时分其降温程度和增湿强度分别比低矮植物高约1°C和约5%。选择合适绿化乔木可有效降低居住小区的热岛现象,增加空气湿度,提供更舒适的室外环境。
