本文通过分析“肺主皮毛”理论的实质，结合烫伤的现代病理机制和中医学病因病机，探讨用该理论指导烫伤的辨证论治。认为“肺主皮毛”理论对指导烫伤的辨证论治十分重要，从肺论治烫伤，在病机上要注重火毒内陷、火毒伤津、气血两虚、阴竭阳脱等变化；在治疗上以清解肺热、凉血通络、补益肺气、滋阴润肺、回阳救逆为法。  相似文献   

Differentiated payments for environmental services schemes: Amethodology proposal     

Carlos R.AGUILAR-GóMEZ  Sergio FRANCO-MAASS  Tizbe T.ARTEAGA-REYES 《山地科学学报》2018,15(8):1693-1710

Payment schemes for environmental services face serious budget constraints in Mexico. Payments are equally distributed among forest owners, and the governmental agencies that make payments to beneficiaries do not evaluate the amount of environmental services produced by forested areas. This lack of evaluation could lead to economic and environmental deficiencies that restrict the possible benefits of such programmes. In general, these programmes do not achieve their conservation objectives, and local beneficiaries are not involved in the design or application of these programmes. Similarly, the Payments for Hydrological Environmental Services (PHES) programme of the State of Mexico, Mexico, makes equal payments to beneficiaries of forested areas considering tree density. The objective of the present work was to create a methodology for determining differentiated payments schemes for hydrological environmental services, prioritising areas that contribute the most to groundwater recharge and promote the participation of society. In the Nevado de Toluca Natural Protected Area, the environmental criteria of forest type, tree density and aquifer overexploitation as well as social participation were considered in a multi-criteria analysis implemented in a Geographic Information System. A methodology was developed to determine differentiated payments based on specific forest characteristics that influence the potential capacity of forests to recharge groundwater reserves in addition to the level of social participation. In particular, social participation is key as it could ensure the viability of PHES programmes as conservation alternatives in forested areas with high groundwater recharge potential.  相似文献

Trace fossils of an amalgamated storm-bed succession from the Jurassic of the Kachchh Basin,India:The significance of time-averaging in ichnology     

Franz T.Fürsich  Alfred Uchman  Matthias Alberti  Dhirendra K.Pandey 《古地理学报》2018,(1)

The uppermost part of the Upper Bathonian Sponge Limestone member, Patcham Formation, of the Jhura Dome of Kachchh Mainland is a thickening-and shallowing-upward succession topped by medium-to thick-bedded hummocky cross-stratified grainstones deposited by storm waves. Occasionally, thin, commonly lenticular, intraclastic-bioclastic silty marl intercalations between the grainstones are highly bioturbated, in contrast to the grainstones, in which, for the most part, trace fossils occur scattered. Large exposures of bedding planes of the grainstones allow the detailed investigation of ichnological features, whereas the high density of traces in the soft marls precludes the identification of any ichnotaxa. Eighteen ichnotaxa have been recorded including Ophiomorpha, Thalassinoides, Taenidium, Gyrophyllites, Chondrites, Dactyloidites, Teichichnus, Bolonia, and Ancorichnus. Except for Ophiomorpha nodosa and Thalassinoides, which generally indicate moderate to high energy conditions and are the dwelling burrows of suspension-feeding to omnivorous crustaceans, the ichnotaxa represent a deposit-feeding behaviour of their producers and thus are characteristic of low-energy environments. The trace fossils form three ichnoassemblages characterized by(1) Ophiomorpha nodosa and Thalassinoides suevicus,(2)?Thalassinoides isp. A, Taenidium, and Bolonia lata,and(3) Ancorichnus. The dominance of traces of deposit-feeders in rocks indicative of high-energy events is counterintuitive and points to their non-contemporaneity. The sediments were deposited during brief highenergy events, whereas the trace fossils were produced when, after waning of storms low-energy conditions prevailed. This time-averaging is particularly pronounced in trace fossils that extend vertically downwards and may reach strata deposited under distinctly different conditions. Thus, environmental interpretations based on trace fossils should refer to colonisation surfaces rather than to the sediment surrounding the trace fossils. In the latter case, interpretations may be erroneous, especially when erosion subsequently destroyed sedimentary evidence of their original environment.  相似文献   

基于B-DEM的颗粒聚合体应力计算和破碎路径模拟     

刘彪  王桥  张宗亮  周伟  FENG Y T  彭张振  李蕴升  徐俊  郭凯 《岩土力学》2022,43(12):3493-3502

结合边界元法和离散元法,提出一种可以进行计算颗粒内部应力和破碎路径的方法。该方法利用离散元法求解颗粒的相互作用和每个颗粒上的荷载。然后利用边界元法计算颗粒的应力分布,为了实现动态平衡,将颗粒的加速度视为恒定大小的体力。但体力导致边界积分方程中出现域积分,故采用直线积分法将域积分转化为边界积分,以保证边界元法降维的优势。为了提高边界元的计算效率,对于几何形状相似的颗粒,以其中一个颗粒作为模板颗粒,只需要计算模板颗粒在局部坐标系中的系数矩阵,其他相似颗粒可以通过局部和全局坐标系之间的映射获得。在得到应力后,基于Hoek-Brown准则来判断颗粒是否破碎。此外,将破坏路径简化为直线,并采用最小二乘法拟合得到破坏路径。  相似文献

利用背景噪声校正海底地震仪钟差

地震记录中时间的精确性对于现代处理技术至关重要。然而,对于由无法直接通信的仪器组成的台阵来说,仪器之间的时钟同步是很困难的。通过全球定位系统(GPS)进行时间同步是陆上的一个选择,但不能用于水下测量,因为电磁信号在水中不能有效传播。如果时钟漂移是线性的,那么可以通过部署前后的全球定位系统同步来估计海底地震仪的时间校正。但对于很多应用来说,这还不够,因为在长时间的实验中,这种漂移的非线性部分可以达到数十到数百毫秒。我们提出两种技术方法来提取同步记录的海底仪器在部署完成之后的时间记录差异。这两种技术都是基于对地震背景噪声的互相关分析,即使时钟漂移是非线性的,也都是有效的。第一种称为时间对称性分析(TSA),易于应用但需要合适的解释,以使噪声互相关函数在时间上是对称的;第二种基于重复地震分析方法,没有这种限制。本文分别讨论了两种方法的优缺点。通过在两组海底地震仪数据集的实际应用,表明两种方法都可以将仪器时钟同步误差控制到约5ms以下(主周期的百分之几)。  相似文献   

大地电磁测深数据处理——4元素和6元素阻抗张量元素的比较研究(英文)   总被引：1，自引：1，他引：0  

M.Shireesha  T.Harinarayana 《应用地球物理》2011,8(4):285-292

阻抗张量元素的计算是在大地电磁测深数据处理的重要一步。按照常规,阻抗张量被定义为以Zxx,Zxy,Zyx,和Zyy为元素的2×2矩阵。在本次研究中,6个元素的阻抗张量的计算使用了一个含有Zxx,Zxy,Zyx,Zyy,Zxz和Zyz分量的2x3矩阵。对上述两类阻抗张量元素的属性进行了分析。利用由印度古吉拉特邦卡奇沉积盆地采集的5个分量大地电磁数据测试了文中的方法。从视电阻率和相位的计算中我们是观察到在大部分的频带范围内4个元素阻抗和6个元素阻抗Zxy和Zyx两类元素区别不大。然而,较长周期时间的数据,如超过100秒,观察到视电阻率的增加和相位的减少。我们还注意到,倾子幅度在大部分时间几乎是零,但较长周期(超过100秒),逐渐呈增加的趋势。卡奇沉积盆地的地电断面表明在较长的周期内浅层近水平层和深层异常高电导性的不均质层都可能是引起大的Hz分量的原因。这表明,磁场垂直分量Hz对在大的2D/3D结构区域内的电场参数估计发挥的重要作用。  相似文献
