The inadequate nutrient content of pellet feeds widely used in recent years in China for grass carp farming led to lipid liver
degeneration in the fish. The present studies show that the pathological features of lipid liver disease are anaemia and hepatic
ceroidosis. Other clinical features are; the ratio of liver to body weight exceeds 3% and lipid content exceeds 5%. Extreme
infiltration of hepaiocytes by lipid results in the following deteriorative effects: swelling of the liver cells, increase
of lipid droplets in the cytoplasm and dislocation of the nucleus, loss of cytoplasm staining affinity, and increased activities
of GOT and GPT in serum. Lipid liver degeneration of grass carp can be divided into three stages: 1) deposition of liver lipid;
2) lipid infiltration of hepatic parenchyma; 3) atrophy of liver nucleus. The causes of lipid liver degeneration are complicated,
but the main cause is assumed to be an imbalance of nutrients in daily feed and the lock of some lipotropic substances.

On the contiguous territories of Russia and China, along the left and right banks of the Amur River (Heilongjiang Province of China, and Amur Oblast′ of Russia), several Precambrian protrusions (Gonzhinsk, Mamynsk, Amurkhe, and Khumakhe) are known. On the Russian territory, along the setting and on the area of the protrusions, lode manifestations, precious-metal deposits, and gold-platinoid placers are known having the industrial imponance. Ultramafites are metasomatically altered more likely by the action of the kate Paleozoic intrusions and produced by them hydrothermae, and are transformed into listvenites. It can be concluded that as one of the sources of precious metals in the placers were the aureoles of listvenitization. This is evidenced by the presence of talc (typomorphic mineral of apoultrabasites) inclusions together with Pt-, Pd- and Ir-bearing gold in the corrosive coatings of the primary platinoids. This conclusion requires the revision of the work strategy of prospecting the lode gold and PGE manifestations within the ore-placer node because apoultrabasites before were considered non-promising for precious metals. 相似文献

为了查明深圳市地面塌陷成因并提出防治措施, 收集整理了深圳市2016-2020年地面塌陷灾害事故数据, 通过现场调查、数据统计分析以及GIS空间分析, 研究了深圳市地面塌陷灾害的时空分布、灾害危害程度以及塌陷成因等。结果表明: 深圳市地面塌陷灾害正处于持续增长阶段, 绝大多数属于小规模塌陷, 且绝大多数发生在雨季, 其中5-8月尤为严重; 地面塌陷发灾点主要集中分布在福田区、罗湖区以及光明区, 主要塌陷地点是市政道路和人行道; 塌陷成因主要包括管网破损、暗渠河道破损、施工不当、雨水冲刷、软土沉降、车辆荷载过大以及其他原因, 其中, 管网破损和施工不当是造成地面塌陷的最主要原因。本研究成果可为深圳市及其他类似城市地面塌陷的防治工作提供一定的参考与借鉴。 相似文献

装配了静电反馈装置的ＬＣＲ－Ｇ／Ｄ型重力仪是目前世界上观测精度最好的相对重力仪，静电反馈装置的转换参数确定得正确与否是影响观测精度的重要因素之一。本文在研究了转换参数数学模型及精度的基础上，介绍了它的标定方法和计算方法，并根据ＬＣＲ－Ｇ－７９３、Ｇ－８５４两台仪器的标定结果，分析了转换参数的变化特征及影响标定精度的诸多因素，最后提出了标定和使用转换参数的注意事项。 相似文献

LCDV-cn是分离自中国养殖牙鲆的淋巴囊肿病病原,给中国牙鲆养殖业带来了严重危害。通过PCR、克隆和测序,获得了LCDV-cn部分基因的序列,证明LCDV-cn与LCDV-C的基因组序列是一致的。比较基因组学分析发现,LCDV-cn基因组中有137个ORF是其独有的、与LCDV-1及其它虹彩病毒无同源区域。对LCDV-cn基因组进行生物信息学分析发现,在LCDV-cn独有的ORF中,有的编码与宿主同源的蛋白,有的编码与DNA复制相关的蛋白,某些ORF编码的蛋白含有跨膜区等。LCDV-cn的独有基因或许对其毒力和宿主范围有关。 相似文献

1 INTRODUCTION The Ussuri / Wusuli River watershed is located in the southeast part of Heilongjiang Province of China, which joins remote regions of Russia. The watershed consists of approximately 26 000 000 ha, which is about two thirds of the watershed ecosystem in Russia, one third in China. The Ussuri River forms part of the border between Russia and China, the shared border stretches more than 1100 km. Khanka/Xingkai Lake lies within both China and Russia. Its total area … 相似文献
