After the Third Plenary Session of the 11th Central Party Committee, China started the reform and opening up. On one hand, the existed planned economy system was under reformation and the socialist market economy system was set up after repeated trials. With respect to ownership structure, the whole-colored public ownership system was forsaken and a new multi-ownership system was established, a system of keeping public ownership as the mainstay of the economy and allowing diverse forms of ownership to develop side by side.

十一届三中全会后，我国进入了改革开放时期，一方面改革原有的计划经济体制，几经探索，确立了社会主义市场经济体制，在所有制结构方面，打破了清一色的公有制结构，实行以公有制为主体，多种所有制并存的多元化结构。

After repeated MTT trials, we found that m/〓-mTNF-α had no clear cellulotoxic effect to target cell SMMC-7721. We consider that SMMC-7721 cells have not sensitive to mTNF-αin vitro.The tumor regression trials of 〓-mTNF-α and 〓-mTNF-αto HCC xenografts in nude mice both showed 5/5 effective.

经过反复MTT实验，均未发现m／〓-mTNF-α以及mTNF-α对SMMC-7721肝癌细胞具有明确的杀伤作用，推测：在体外SMMC-7721细胞对mTNF-α不敏感，mTNF-α不能对细胞产生直接的杀伤作用。

The correct rates and the mean response latencies were subjected to ANOVA with repeated measures. Result:In both supraliminal and subliminal affective priming tasks, the mean response latencies were significantly longer for affectively incongruent trials, as compared to those for affectively congruent and control trials. The correct rates for affectively incongruent trials were the lowest.Subjects were relatively slower to respond to positive target pictures than to negative target pictures(96.9%/95.3%,97.6%/95.8%).In subliminal affective priming task, there were no differences of correct rates and latencies between alexithymics and nonalexithymics. In supraliminal priming task, the latency of alexithymics was longer than that of nonalexithymics (536.3ms/496.4ms).

结果：在阈下和阈上启动任务中的正确率，情绪启动状态的主效应均显著（F=14.38，P=0.000，F=3.28，P=0.042），启动和控制状态的反应正确率均高于非启动状态（阈上：启动状态97.3%/非启动状态96.1%，阈下：启动状态96.8%，控制状态96.8%，非启动状态94.7%），而启动状态的平均反应时则均短于非启动状态（阈下：启动，537.2ms；控制，550.8ms；非启动598.4ms；受试对负性图片的反应正确率显著高于正性图片（如阈下：96.9%/95.3%，阈上：97.6%/95.8%，对负性图片平均反应时显著短于正性目标图片；在阈下启动任务中，述情障碍组与非述情障碍组在正确率和平均反应时上均无显著性差异；在阈上启动任务中，述情障碍组的平均反应时显著长于非述情障碍组（536.3ms/494.4ms）。

In this experiment, methods of artificial inoculation were used to evaluate 17 species (including 26 types), 2 mutants, 3 cultivars, and 4 hybrids of Malus for their resistance to Valsa Mali. After 3 years repeated trials, it showed that 7 of them are highly resistant 2 are resistant, 2 are medium resistant and others are different grades of susceptible resources.

在1983年接种方法研究的基础上，于1985—1987年采用人工田间砸伤接种法，对苹果属17个种的26个类型、2个变种、3个品种和4个杂交种，共35份种质资源材料进行抗腐烂病的系统鉴定，经3年重复，鉴定出高抗级种质资源7份，一般抗2份，中抗2份，其它均为感病各级的资源。

But I think given the media's repeated attempts to make a circus- liken environment out of criminal trials, I'm beginning to change my opinion of that, and maybe they don't belong in courtrooms.

但是鉴于媒体不断重复对刑事案件的马戏团搬的报道，我已经有点动摇了，也许他们并不属于法庭这个领域。
