This dissertation used 6 celery lines. in 14℃/10℃ and 10℃/10℃, the low temperature stress tolerance of lines 10, 14, 16, 20, 22, 24 are evaluated by mensurate weight growing, stability of cell membrane, dissociative praline, dissolvable sugar, dissolvable protein. The main results are as follows: It is good putting celery plants in 10℃/10℃ when we study the changes the celery materials make under low temperature stress.

实验选择6个芹菜品系，在18℃/14℃和14℃/10℃、10℃/10℃低温胁迫处理下，通过测定生长量、膜稳定性、游离脯氨酸、可溶性糖、可溶性蛋白质等指标综合评价筛选确定了6个（10、14、16、20、22、24）品系的耐低温胁迫能力，结果表明：低温胁迫研究中采用10℃/10℃处理芹菜幼苗比较合理。

结果 产妇血铅水平的高低与新生儿脐血铅的高低呈正相关(X^2=229.1， P.05)。

Since the output signal from fringing field dielectrometry sensors under a low frequency driving voltage are very low, the shield-drive, signal buffer and band-pass filter are adopted to improve SNR. With the signal gain and phase angle from a transform circuit, the complex permittivity of pressboard are obtained.

鉴于边缘场电容式传感器在低频正弦驱动信号作用下输出的感应信号非常微弱，调理电路采用驱动屏蔽方式进行测量信号缓冲，用带阻滤波器提高信噪比，并利用相应的变换电路求出电容系统的相位角和幅值增益，从而得到绝缘纸板的复介电常数。

This essay analyzes the method and procedure of ice-making recorded in Huai Nan Wan Bi Shu, and creatively proposes that the principle of "ice-making in summer" is refrigeration through the quick evaporation of water to absorb heat under low pressure, and that ice is made on the fine silk at the mouth of an urn, but not inside the urn at its bottom as it was conventionally thought. The essay points out three necessary conditions which should be fulfilled in order to realize "making ice in summer": low relative humidity (less than 26%), large volume of the urn (about 100 L) and proper air temperature (about 20℃).

分析《淮南万毕术》所载制冰方法和过程，提出低压下水快速蒸发吸热制冷是"夏造冰"的制冰原理；结冰的部位不是传统观点所认为的瓮底，而是在瓮口的嫌上；指出要实现"夏造冰"，需满足三个条件：相对湿度低（低于26%）、瓮的容积大（100升左右）、空气的温度适当（20℃左右）。
