＜正＞The Yalong River,flowing through Sichuan Province,China,with 21 cascade hydropower projects totaling 30,000MW planned on its main stream of 1571km,is one of China’s 13 hydropower *** Jinping Hydropower Scheme,located on the lower reaches of the Yalong,consists of Jinping Ⅰ Project（3,600MW）and Jinping Ⅱ Project（4,800MW）,with a total installed capacity of 8,*** Ⅰ has a concrete arch dam of 305m high and a reservoir of 7.77 billion cubic meters;Jinping Ⅱ takes water from Jinping Ⅰ reservoir through 4 power tunnels of 16.6km each,thus leaving behind the big river bend of 119kin with reduced river *** the scheme is completed,the huge reservoir formed by the high dam,together with the long river section of reduced flow,will cause certain impact on fish propagation in the project-affected river course. This paper analyzes in detail the possible impact that construction of Jinping Scheme would cause on fish resources,and discusses the comprehensive measures to be taken to cope with the adverse effect,which include multi-level water-taking from the reservoir,release of ecological discharge to the flow-reduction river section,fish multiplication and free breeding,and establishment of fish germplasm *** protection plans on Jinping Scheme are quite representative,and can be of reference to fish protection measures of other large hydropower projects.

本文针对深水湖泊水库三维温度场计算量较大的特点提出了一种计算快捷的湖泊水库三维温度计算模型。该模型根据控制方程中各物理过程的变化特点采用算子分裂法求解,快过程采用隐式求解,慢过程采用显式求解,协调了不同物理过程模拟的时间步长;文中对σ坐标系下的斜压梯度力和水平扩散项的表达式采用z平面均值扣除法进行处理,提高了二者的计算精度,更加适合于湖泊水库的应用。文章最后采用两个算例对模型进行了验证,表明了模型的有效性和实用性。

The CDEX-10 experiment searches for light weakly interacting massive particles, a form of dark matter, at the China Jinping Underground Laboratory, where approximately 10 kg of germanium detectors are arranged in an array and immersed in liquid nitrogen. Herein, we report on the experimental apparatus, detector characterization, and spectrum analysis of one prototype detector. Owing to the higher rise-time resolution of the CDEX-10 prototype detector as compared with CDEX-1 B, we identified the origin of an observed category of extremely fast events. For data analysis of the CDEX-10 prototype detector, we introduced and applied an improved bulk/surface event discrimination method. The results of the new method were compared to those of the CDEX-1 B spectrum. Both sets of results showed good consistency in the 0-12 ke Vee energy range, except for the 8.0 keV K-shell X-ray peak from the external copper.

We report the first results on 76Ge neutrinoless double beta decay from stage one of the China dark-matter experiment （CDEX）. A p-type point-contact high-purity germanium detector with a mass of 994g has been installed to detect neutrinoless double beta decay events, as well as to directly detect dark matter particles. An exposure of 304kgd has been analyzed over a wide spectral band from 500keV to 3MeV. The average event rate obtained was about 0.012 counts per keV per kg per day over the 2.039MeV energy range. The half-life of76Ge neutrinoless double beta decay derived based on this result is 70v2〉6.4× 1022 yr （90%C.L.）. An upper limit on the effective Majorana-neutrino mass of 5.0eV has been achieved.
