HFRS(HIAF FRagment Separator) will be the radioactive secondary beam separation line on High-Intensity heavy-ion Accelerator Facility(HIAF) in China. Several TPC detectors, with high count rates, are planned for particle identification and beam monitoring at HFRS. This paper presents an event-driven internal memory and synchronous readout(EDIMS)prototype ASIC chip. The aim is to provide HFRS-TPC with high-precision time and charge measurements with high count rates and a large dynamic range. The first prototype EDIMS chip integrated 16 channels and is fabricated using a 0.18-μm CMOS process. Each channel consists of a charge-sensitive amplifier, fast shaper, slow shaper, peak detect-and-hold circuit, discriminator with time-walk compensation, analog memory, and FIFO. The token ring is used for clock-synchronous readout. The chip is taped and tested.

为了分析不同生育期水分亏缺下,设施延后栽培葡萄土壤生物学特性(包括土壤蔗糖酶、脲酶、土壤微生物量碳和有机碳)的变化趋势以及不同处理对果实产量与品质影响,于2013-2015年在甘肃省张掖市灌溉试验站进行了设施延后栽培葡萄灌溉试验的研究。结果表明,萌芽期-新梢生长期水分亏缺处理能够提高土壤蔗糖酶活性,开花期水分亏缺处理与CK处理相比无显著性差异,果实膨大期-着色成熟期水分亏缺处理对本阶段土壤蔗糖酶活性具有抑制作用。萌芽期是最适宜通过水分亏缺方式提高土壤蔗糖酶活性的时期。萌芽期水分亏缺处理和着色成熟期水分亏缺处理对土壤脲酶活性都具有抑制作用,新梢生长期-果实膨大期水分亏缺能提高相应生育阶段的土壤脲酶活性。而对土壤微生物熵值来说,新梢生长期水分亏缺处理对其具有显著提高的作用。根据相关分析和典型相关分析结果,果实产量增加时,土壤蔗糖酶活性增大,而土壤微生物量碳含量却显著减少;随着土壤脲酶活性增大,果实中可滴定酸含量明显增大。
