The 40Ar-39Ar age method is employed in this work to analyze the auriferous altered rocks from the middle-deep section of the Q875 gold-quartz vein in the Xiao-qinling area, and the results show that the main gold deposition of the Q875 occurred in ca. 12.-12. Ma. As a typical gold-bearing quartz vein in this gold-rich area, the age data obtained from the Q875 also constrain on the metallogenic time of the lode gold deposits developed in the same geological settings. This geochronological study supplies new evidence for further understanding the timing of gold mineralization, the genesis of gold deposits and the geodynamic settings in Xiaoqinling area.

The Yingfeng rapakivi granite on the north flank of Qaidam is a newly discovered Proterozoic rapakivi pluton in China, which was found after the discovery of Shachang rapakivi in Miyun County, Beijing and Kuandian rapakivi in Jilin province. Yingfeng rapakivi pluton is ex-posed on the north side of the suture belt between Qinling-Kunlun orogenic belt and North China plate. U-Pb zircon isotopic dating and Ar-Ar isotopic dating of both hornblende and K-feldspar from the Yingfeng rapakivi granite have been conducted. The results show that the age of (1776±33)Ma at the upper intercept in Concorde diagram represents the age of formation of the plu-ton, whereas the age of (52. 2.1) Ma at the lower intercept and Ar-Ar mineral dating of horn-blende and K-feldspar correspond to the age of a later event affecting the pluton, suggesting that Yingfeng pluton has ever been affected by strong regional Caledonian-Hercynian tectonic movement after its formation. The discovery of middle Proterozoic Yingfeng rapakivi granite pro-vides a petrologic evidence for the timing of cratonization of both the continental crust basement in western China and the basement of the North China plate and for a rifting event taking place in the mid-Proterozoic, suggesting that an amalgamation of ancient China continents had ever happened during the L liang Movement?between the early Proterozoic and the mid-Proterozoic.

1 geological setting THE Sb mineralization zone in the south margin of North China platform is located in the transitional edgeof North China plate and Yangtze plate, belonging to Qinling fold system, whose tectonic line is inNWW-SEE direction regionally. Because of the huge compression caused by the collision of the twoplates, the rocks undergone strong deformation and metamorphism have very complicated structures. Theregional deep fault-Shuanghuaishu fault-controls Sb-mineralization zone belt, and all the Sb-oredeposits or mineralized spots appear alone at the very southern margin of the fault. The lithostragraphirunits in the mineralized zone are relatively simple, mainly composed of Jiebei Group （Pt2./sub>J2./sup>） of QinglingFormation （with middle-high metamorphsim） and the upper Triassic system （with little metamorphism）.

Landslide prediction is one of the most important aspects of prevention and control for geological hazards and the environmental protection. In order to study the nonlinear methods for landslide prediction, the synergetic-bifurcated model of predicting the timing of slope failure is established by combining Synergetics with Bifurcation Theory based on single-state variable friction law in this paper. The synergetic effects and bifurcated process of the factors in the slope evolution can be characterized in the model. Taking the Xintan Landslide as an example, the prediction of landslide is carried out based on the model suggested.

关键词： friction law, landslide, synergetic-bifurcated model, time prediction.

The development of single-chain antibody （scFv） by recombinant gene expression is an important milestone for cancer gene therapy. Single-chain antibodies are reconstructed for cancer-targeted therapy to provide good penetration into tumor tissue and to improve their pharmacokinetics in vivo, offering a clinically valuable application. However, there may be some variation between the structure and function of the fusion proteins. Analyzing the interaction region between the antibody and the antigen, and the binding sites for molecular conformation, it is clear that the existing antibodies need to be modified, enhancing the biological activity of the antibodies. Based on the view that bio-molecular computer models are closely integrated with biological experiments, a bio-molecular structure–activity relationship model can be established in terms of molecular conformation, physical and chemical properties and the biological activity of single-chain antibodies. On the one hand, the structure–activity relationship is clear for new immune molecules at the gene expression level. On the other hand, a single-chain antibody molecule can be designed and optimized for the cancer-oriented treatment. In this review, we provide the theoretical and experimental basis for the development of singlechain antibodies appropriate for cancer therapy.

土地覆被类型是水循环过程的重要影响因子,为探究不同土地覆被下洞穴滴水的水文特征及其影响因素,文章选取了贵州岩溶区不同土地覆被下的清江洞(土层厚,植被中等)、广顺洞(土层薄,植被好)和石将军洞(土层薄,植被差,顶板厚)3个洞穴,基于滴水流量、土壤含水量及气象数据进行研究。结果表明:(1)3个洞穴的滴水流量均存在季节性变化规律,滴水在降水输入少的旱季易发生断流;(2.由于土壤的截留和储存作用,使得洞顶土层覆盖厚的清江洞相较于广顺洞和石将军洞在雨季8月到10月期间表现出特有的流量低值现象,且全年土壤含水量的最低值也出现在此时期;(3)3个洞穴滴水流量的年均值为石将军洞(1.185 mL·min^(-1))>清江洞(0.600 mL·min^(-1))>广顺洞(0.2.6m L·min^(-1)),流量的全年稳定程度为石将军洞>广顺洞>清江洞;(4)植被对洞穴滴水水文特征的影响弱于土壤,土壤发育较好的洞穴(清江洞)比土层薄但植被覆盖高的广顺洞全年更容易断流,另外顶板厚度大的洞穴(石将军洞)全年滴水流量稳定程度最好。综上,洞穴滴水流量除受降水、气温、湿度等气象条件影响外,还受土地覆被、含水层顶板厚度的影响。

琼东南盆地属于南海北部陆缘拉张盆地,但是由于其不同的发育历史及红河断裂的影响,具有与东部陆缘盆地不同的构造特征。琼东南盆地和珠江口盆地在地壳结构、基底特征等方面存在差异,但是这种差异的原因还不清楚。新生代沉降速率发生多期变化,并存在裂后异常沉降、沉降延迟等现象,其形成机制尚需要进一步研究;平面上,构造具有迁移性,但是对不同地质时期的构造迁移方向仍存在不同的看法。盆地沉降中心和沉积中心经历了由裂陷期和裂后早期的较好重合到裂后晚期的逐步分离,直至完全分离的过程。盆地形成与地幔流的关系,以及红河断裂对盆地裂后沉降迁移的影响,也都是需要进一步确定的工作。鉴于以上各方面存在的问题,对琼东南盆地与南沙的共轭关系、盆地异常沉降、红河断裂及内部构造转换带对构造迁移的影响、以及琼东南盆地与珠江口盆地的比较等方面的研究是下一步工作的重点。
