Using the value distribution theory, the author studied the uniqueness of meromorphic function concerning multiple value .

应用值分布理论，在涉及重值情况下进一步研究了亚纯函数唯一性理论中Gross 。F提出的一个问题，获得如下结果：设集合S ={ω∈C|P =aω7- 42ω2 +70bω- 30b2 =0 }，其中a ，b为不等于零的常数，ab5≠ 2。

A new type of flexible microelectrode array s based on parylene is developed in this paper.

结果表明，基于Parylene 柔性微电极阵列的阻抗值在中频段呈现高通特性，其阻抗值及相位角分别为2 000~100Ω和-20°，有利于实现植入式视觉假体系统对视神经进行功能性电刺激。

In the 65 recorded neurons, the results showed: Characteristic frequency , minimum threshold and response latency was between 18.9 and 76.7 kHz (42.94 ± 11.29), 29 and 80dB SPL (58.65 ± 12.62), 3.1 and 13.4 ms (6.10 ± 1.47), respectively; CFs increased with the recording depth, but CF and MT were not correlated; There were three different types of discharge patterns in the IC, including phasic pattern (73.9%), chopper (15.4%) and tonic (10.7%); The types of frequency tuning curves were all V-shaped, most of which were wide type and few were narrow type.

结果发现，在所得的65个下丘神经元中：特征频率在18.9～76.7kHz(42.94±11.29)之间，最小阈值在29～80dB SPL(58.65±12.62)之间，潜伏期在3.1～10.4ms(6.10±1.47)之间；特征频率随记录深度的增加而增大，与最小阈值之间没有显著相关性；发放类型包括相位型(73.9%)、梳齿型(15.4%)和紧张型(10.7%)3种基本类型；频率调谐曲线均为开峰型，多数神经元(72.3%)调谐曲线较宽阔，少数(27.7%)较狭窄，并且多数神经元的频率调谐曲线高频边比低频边陡。

What is the minimum possible value of m + n?

问 m + n 所有可能值中的最小值是多少？

However, the missing values of the database will affect the data analysis, hence, it is very important to resolve the missing value problem.

而资料库中遗失值的存在，往往会影响到资料分析的品质，所以如何妥善处理这些遗失值是非常重要的关键。

In incomplete information system, using variable attribute rough set model, need not to evaluate missing value, we can obtain the irregular decision table without missing value.

在不完全信息系统中，使用变属性粗糙集模型，不必对缺失属性值进行估计，最后得到了不含缺失属性值的不规则决策表。

0M/s.(4) The barchans dunes developed in narrow un-modal wind regime, the value of RDP/DP is greater than 0.8; the compound longitudinal dunes mainly developed in modal wind regime whose value of RDP/DP is about 0.55; the dome dunes developed in those areas that have directional winds and their force is balanced; and the star dunes mainly distributed in areas which have wavy terrain or approach mountains.

4塔克拉玛干沙漠新月形沙丘及沙丘链主要是在窄单峰风环境中发育而成，RDP/DP值一般都在0.8以上；复合型纵向沙垄主要是在双峰风况条件下发育而成的，RDP/DP值在0.55左右：穹状沙丘形成于均衡的多风向地区；而金字塔沙丘一般都形成于下伏地面微有起伏或邻近山岭的地带。
