Recently, it has been found that some inducers such as retinoids acid and yeast containing Se can prevent and reverse PLGC of rats to some extent. But all of these data are obtained from animal experiments, information of clinical research has not been reported. Natural β-carotin and folic acid can reverse dysplasia and intestinal metaplasia of gastric mucosa to some extent, but these effects are required to be further investigated.

晚近发现维甲酸类诱导分化剂及硒酵母对大鼠PLGC演变至胃癌有一定阻抑预防和逆转治疗作用，但均仍停留在动物实验阶段而未用之于临床；天然β-胡萝卜素和叶酸干预治疗后能一定程度地逆转胃粘膜异型增生和肠化生，值得进一步深入。

A set of the laboratory experiments were also performed to simulate the physical and chemical changes in the rain fall process and to study the factors affecting the pH value of cloud water.

以往的研究表明，大气中酸性物质的增加、碱性物质的减少或促使这种变化发生的条件的出现均为导致雨水酸化的决定因素。

Results indicated that the variation was significant from treatment to treatment. S-deficiency caused bulging chloroplasts, loosening and dishevelled grana lamella, reducing organelle, and damaged chondriosome in mesophyll cells of the leaves, and empty cells of the roots, while S-excess, however, led to densification, condensation and randomization of grana lamella of the chloroplasts of the leaves, and separation of cytoplasms from walls of the cells of the roots.

结果表明，受S素营养胁迫的水稻，其根系及叶片的超微结构均发生了显著的变化：低S胁迫会造成水稻叶片叶肉细胞内的叶绿体结构肿胀，基粒片层松驰、散乱，细胞器减少，线粒体结构被破坏，根系细胞内几乎没有内含物；S浓度高则会使叶片叶绿体基粒片层致密、浓缩，无规则化，根系细胞发生质壁分离。

Results By using optical microscope,the neurocytes of hippocampus in experimental group were observed to denaturalize,tumefy,destroy and disappear.And under electron microscope,the karyon was irregular,nucleoles deviated,chondriosome tumefied,crista collapsed,membrane was damaged,substance cavitated.Such changes were more evident with the increased paroxysm of epilepsy,the parameters between control group and operation group had no difference（P＞0.01）.But make a monofactorial variance analysis among cells' number,area,circumference and integral optical density in different groups,it showed that there were significant differences between optional two groups（P.01;at the same time,the more serious injury in hippocampus,the more powerful GFAP immunoreaction was.

结果： 实验组海马区光镜下可见神经细胞变性、肿胀、坏死及神经细胞脱失改变，电镜可见细胞核形态不规则、有切迹、核仁偏位、线粒体肿大、嵴断裂、膜破损和基质空化等改变，随癫痫发作次数增加上述改变越明显，对照组与手术对照组比较，各参数差异无显著性（P＞0.05），将不同组别大鼠细胞数、面积、周长、积分光密度分别作单因素方差分析，不同组别间均差异有显著性（P.01），同时观察到海马区GFAP免疫反应阳性的胶质细胞随海马损伤的加重而GFAP免疫反应增强。

The design process of the passive optical athermalisation was elaborated by an example. The result was analyzed with an optical design software. It shows that the design result meets the requirement of eliminating the thermal difference and chromatism at the temperature range of -40℃～+60℃.

最后用实例说明光学被动式无热化设计的求解过程，并通过光学设计软件对结果进行分析，说明该设计结果在-40℃～+60℃温度范围内均满足消热差和像差要求。

The coefficients for eliminating the thermal difference and chromatism of common infrared materials were described by Cartesian coordinates.

The results (Fig. 1) show that the capability for producing monacolin K by Strain M12-69 initialized from Strain M12, is almost 9 times higher than that of Strain M12, whereas the citrinin concentrations produced by both strains remained at the lower levels.

结果（图1 ）显示，有能力生产莫纳可林K的应变的M12 - 69初始化从应变的M12 ，是近9倍以上应变的M12 ，而所产生桔霉素浓度均株仍处于较低水平。

By the analysis of coal two-step extract by FTIR and comparison of extraction rate, we can see the two-step extraction with combination of cyclohexanone and CS〓-NMP (1: 1, v/v) has higher extraction rate as to coal of different degree of coalification.

4环己酮和CS〓－MP（1：1，v/v）复合溶剂的两步抽提对不同煤化程度的各煤种均保持了较大的抽提率，基本达到对不同煤种的可溶化要求。

Recall that, in the Kolmogorov axiomatization, measurable sets are the sets which have a probability or, in other words, the sets corresponding to yes/no questions that have a probabilistic answer.

延期开工的Kolmogorov宣布要衡量所有套职能有限许多坐标限制在于衡量子寅。换句话说，如果是/否的问题回答f可看的价值观念在许多最有限坐标，然后它有一个概率的答案。

The experimental results showed that the algorithm can filter singular points and remain fixity of the target edge.
