In the light of field features in desertification areas, the data quality and band combination of different bands are assessed, the indicators, principles and methods for data assessment and band option are put forward to, and optional band combination for desertification monitoring is determined primarily. The data pre-treatment model for desertification monitoring is developed after studying the pre-treatment algorithm of restoration and rebuilding of hyperspectral resolution data. The spectral features and variation rules of different objects in experimental areas are understood and analyzed. The different classified methods are given and discussed on the basis of characteristics of desertification region. The remote sensing quantitative retrieval model for the appraisable factors of desertification monitoring are founded.

In this study, we therefore hypothesized that changes in intrapelvic neurokinin system and DOR detrimental to renal sensory response in nephropathies and HPC may affect above molecules to prevent the loss of ARNA response.

因此，我们假设快肽、神经激肽受体以及DOR可能在肾脏疾病所引发的肾感觉功能失调中扮演相当重要的角色；并且低氧预处理可能透过这些因子来达到其感觉功能的保护效果。

The results obtained are as follows:(1) injection of 50, 100, and 200 nmol/kg adenosine into the renal artery increased the renal afferent nerve activity in a dose-dependent manner with unchanged arterial pressure;(2) pretreatment with 8-cyclopenthl -1,3-dipropylxanthine (DPCPX, 160 nmol/kg), an adenosine A1 receptor antagonist, partly abolished the effect of adenosine; and (3) pretreatment with a nitric oxide synthase inhibitor N w-nitro- L -arginine methylester (L -NAME, 0.1 mmol/kg) significantly enhanced the ARNA response to adenosine.

结果表明：(1)肾动脉内注射50， 100和200 nmol/kg腺苷可呈剂量依赖性地兴奋肾神经传入纤维的活动，而动脉血压不变。(2)肾动脉内预先应用选择性腺苷A1受体阻断剂DPCPX (160 nmol/kg)，可部分阻断腺苷对肾神经传入纤维的兴奋作用。(3)静脉应用一氧化氮合酶抑制剂 L -NAME(0.1 mmol/kg)预处理，延长并增强了肾神经传入纤维对腺苷的反应。

结果表明：(1)肾动脉内注射50，100和200nmol/kg腺苷可呈剂量依赖性地兴奋肾神经传入纤维的活动，而动脉血压不变。(2)肾动脉内预先应用选择性腺苷A1受体阻断剂DPCPX(160nmol/kg)，可部分阻断腺苷对肾神经传入纤维的兴奋作用。(3)静脉应用一氧化氮合酶抑制剂L-NAME(0.1mmol/kg)预处理，延长并增强了肾神经传入纤维对腺苷的反应。

Previously we found that ARNA response was impaired in rat nephropathies of puromycin aminonucleoside, lipopolysaccharide, or cyclosporine A, and these sensory defects were ameliorated in rats pretreated with hypoxia preconditioning. However, the underlying mechanisms are not clear.

依据本实验室之前研究，在许多肾病变中，包括：嘌呤霉素核苷酸（puromycin aminonucleoside， PAN）、内毒素（lipopolysaccharide， LPS）、以及环孢菌素A（cyclosporine A， CsA）所引起的肾病变中，都观察到肾脏感觉功能失调的现象，而且本实验室之前的研究也发现低氧预处理能够减缓这些疾病中肾感觉功能失调的现象。

During preprocessing phase, build a hierarchical decomposition of the environment using an octree and create HLODs. At run time, use multiple threads to render the environment: use visibility culling to cull those invisible blocks, choose HLOD according to screen error, and also use data management and attemperation to update the data in main memory.

The paper carries on qualitative analysis to the acetone extractives before and after discoloring, shows the main components of the extractives and then takes comparison. The results shows :①The hydroxyl is oxidized and then shifted to the carbonyl,carboxyl, ester and ketone groups during inducing discoloration under the pretreatment conditions,which makes the wood color deep;② There are plenty of auxochromic groups in the acetone extractives of silver chain, the interaction between the auxochromic groups and the chromophoric groups makes the wood color deep.

摘 要：本文通过对刺槐变色前后丙酮抽出物的定性分析，得出变色前后丙酮抽出物的主要成分，进行对比分析，初步得出抽出物对诱发变色的作用为：①变色前后羟基在预处理条件下氧化成羰基，羧基，酯基和酮基等官能团，使木材颜色加深；②刺槐丙酮抽出物的主要成分中含有大量助色基，这些基团会与木素中的发色基团相互作用，使木材颜色加深。

The hydroxyl and carboxyl, belonging to auxochromic groups, were oxidized into the carbonyl and ester groups, belonging to chromophoric groups, during inducing discoloration under the pretreatment conditions, which makes the wood color deeper. There were plenty of auxochromic groups and chromophoric groups in the acetone extractives of silver chain. The interaction between the auxochromic groups and the chromophoric groups made the wood color deeper.
