[Method] DOM + LHRH-A2 was used to induce spawning of loach,then after fertilization,the embryos were cultured into freshwater water with temperature from 24 to 26 ℃ and pH from 7.0 to 7.5. The embryonic development of loach was observed and 27 concrete morphological characteristics and development time of loach from fertilized egg to newly hatched larval period were described in detail. [Result] The embryonic development of loach could be divided into cleavage stage,blastocyst stage,gastrula stage,neurula stage and organogenesis stage. The loach embryo from fertilized egg to out membrane period was 30 h 45 min in fresh water from 24 to 26 ℃ and pH from 7.0 to 7.5. [Conclusion] It provided important reference for studying artificial propagation and genetic breeding of loach.展开更多

Astroparticle experiments benefit from high integration, smallsize and low power consumption. In this paper an analog chip named ARCHGARD (Analog Readout Chip for High energyGamma Ray Detector) for high energy physics experiment is introduced. ARCHGARD is a readout chip, in chartered 0.35 mSiGe technology, for photomultipliers (PMT) array readout. The chip is designed for the Large High Altitude Air Shower Ob-servatory (LHAASO) project. The ASIC integrates 16 independent and auto-triggered channels with variable gain and variableshaping time. It provides analog output for charge measurement, which is performed from 1 up to 3000 photo-electrons (p.e.).The integral nonlinearity of the whole input range is less than 1% and the equivalent input noise is less than 1/10 p.e.
