1·And the capacities of compressor could be selected by on-off switch along with the change of burthen of evaporator, which is a main characteristic of the central refrigeration system model.
集中供冷系统仿真数学模型的主要特点是压缩机可以根据蒸发器总负荷大小选择性开关不同的档位，相应的输入输出参数也随之改变。
2·Neoadjuvant chemotherapy can minish burthen of tumor and lower the clinical stage, and increase resection rate of cancer.
新辅助化疗可以减小肿瘤负荷，降低临床病期，提高肿瘤的手术切除率。
3·The burnout of police mainly come from work environment, work burthen, work fatalness, and social support.
警察工作倦怠的来源主要是来自工作环境、工作负荷、工作危险性和社会支持。
4·Quantity in tube is the cable with burthen.
穿管根数指有负荷发热的电缆， 根数。
5·Suction gas pressure goes up as the compressor run at the lower speed in the lower burthen, and this is beneficial to lower systems energy-consume.
在负荷较小时，压缩机采用低速运转，吸气压力升高，这对系统降低能耗是有利的；
