Operation along crop row is a basic function of vision navigation for agricultural robot. The complex external factors of working environment in the field, such as existed shadow and weather change etc., make the navigation parameters extracting become more difficult.

完成沿作物行的行走作业是农业机器人视觉导航系统的一个基础功能，但是由于田间环境的复杂性，比如阴影的存在和天气的恶劣变化等外界因素的影响使导航参数的提取变得困难。

Finally, tests of following crop row showed that shadow removal method based on illumination invariant image satisfied real-time requirement of system and improved the robustness of extracting navigation parameters under variable daylight illuminants.

最后，通过作物行跟踪试验表明，基于光照无关图的阴影去除方法不仅满足了导航实时性的要求，而且使农业机器人在光照变化的情况下导航参数提取的鲁棒性有了更大的提高。

Double—blind, randomized, placebo—controlled clinical trail on Chronic Congestive Heart Failure with Shengmai capsule treatmentResult:5.1 The left room shoots the blood score EF value:EF value three hour point total to distribute the characteristic obeys positive the normal distributes, proceeding the independent sample t examination: diagnosing moment hour point an EF value variety of placebo group and treatment group have no to show the difference of obvious; 12 weeks with 24 week hour point, an EF value variety of placebo group and treatment group also have no to show the difference of obvious.

两组EF值再分别作自身前后对照——配对样本t检验：安慰剂组在就诊时分别和试验12周、24周进行对照，发现其自身前后的EF值并无显著性差异(P＞0.05)；治疗组也作同样对照，虽然EF值在三个时点的变化均无显著性差异(＞0.05)。5.2 NYHA心功能分级安慰剂组和治疗组治疗前后的非参数检验——Wilcoxon检验：两组治疗前后心功能分级对照无显著性差异(＞0.05)。

Based on PVT and sand packed tube, the high pressure characteristics such as viscosity, expansion coefficient and minimum miscibility pressure were measured for mixture of crude oil and carbon dioxide, and the oil and gas production during multi contact experiments under constant and declined pressure was investigated, Lastly, the production performance of sand packed tube similar to low permeable reservoir.

通过PVT筒和填砂管气液平衡等模拟实验，测定原油与CO2体系的黏度、膨胀因数和最小混相压力等高压物性参数，研究了恒压和降压下5次CO2接触过程中原油和气体的产量变化，并对比研究模拟特低渗填砂管与PVT筒CO2吞吐实验的开采动态。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.
