At first , based on the results of in - situ load tests , the load - settle curves are acquired , and the effects of different reinforcement parameters are presented . these parameters include the linear density ratio ( ldr ) ; the location of the top layer of the geobelt measured from the bottom of the load plate ( u ) ; the different materials of geobelt ; the number of reinforcement layers ( n ) and the distance between the two layers of geobelt ( a h ) . these results show that the bearing capacities of the reinforced composite foundation can be improved and the settlement can be reduced
首先，通过现场载荷试验，获取了加筋垫层复合地基荷载-沉降曲线，从筋带铺设的密度、筋带的首层间距、不同筋带材料、加筋层数以及双层筋带的层间距等几个方面分析了以上加筋参数对加筋复合地基承载力的影响，指出筋带的存在提高了加筋复合地基的承载力，减小了沉降。
Do not use the cloud or glass loading the device cloud the density low , the flap high , can affect the sound effect . glass density ratio cloud the is high , however not thick and solid , the flap more seriously . can use to spend the or , and it is tallest to is , density particularly , loading device than ideal , but the thickness want 3cm above
别用云石或玻璃承载器材云石密度低，谐振高，会影响音响效果。玻璃密度比云石高，却不厚实，谐振更严重。可用花岗石或麻石，尤其是麻石，密度最高，承载器材较理想，但厚度要3厘米以上。
By comparing and analyzing the advantages and disadvantages of three kinds of voltage reference circuits , type of current density ratio compensation 、 weak inversion type and type of poly gate work function , a cascode structure of type of current density ratio compensation is chosen to form the core of voltage reference circuit designed in this paper . applying the negative feedback technology , an output buffer and multiply by - 2 - circuits are designed , which improve the current driving capability
然后通过比较和分析电流密度比补偿型、弱反型工作型和多晶硅栅功函数差型三种带隙电压基准源电路结构的优缺点,确定了电流密度比补偿型共源共栅结构作为本设计核心电路结构,运用负反馈技术设计了基准输出缓冲电路、输出电压倍乘电路,改善了核心电路的带负载能力和电流驱动能力。
