The results showed: there is the apoptosis of the myocardial cells during the period of I/R. The further study showed that there is the express of Bcl-2, Bax and Fas in the model of the cultured myocardial cells which were treated with ischemia-reperfusion The express of Bax, Fas proteins increase obviously. The overexpress of Bcl-2 is weak positive which shows that there is certain relationship between the apoptosis of the myocardial cells and the higher express of Fas and the ratio descent of the Bcl-2/Bax.

结果表明：在I/R过程中确有心肌细胞凋亡现象，而且进一步研究发现在培养的心肌细胞缺血-再灌注的模型中均见Bcl-2、Bax、Fas的表达，Bax、Fas蛋白的过度表达明显增加，Bcl-2的过度表达仅呈弱阳性，表明心肌细胞的凋亡与Fas的高表达，Bcl-2/Bax的比例下调有一定的必然联系。

The results showed that the irradiation treatment in the dose of 2.0-8.0kGy is not significantly effective to the contents of total sugar, crude protein and crude fat in walnut powder. The content of crude fiber in irradiated walnut powder increased, but not significantly. The irradiation had barely change on the contents of the lauric acid and myristic acid, and non-significant effects on the contents of palmitic acid, palmitoleic acid, stearic acid, leinoleic acid, arachidic acid and linolenic Acid. However, the irradiation contributed to significant increase in the content of oleic acid with the irradiation dose. When irradiation dose reached 8.0kGy, the content of oleic acid had an increase of 4.3%. Irradiation will not change the sensory index of walnut powder much when irradiation dose is lower than 8.0kGy.

结果表明：剂量为2.0～8.0kGy时，辐照对核桃粉中的总糖、粗蛋白和粗脂肪含量无显著影响；辐照后的粗纤维含量有一定的增加，但不显著；辐照对核桃粉中的月桂酸和肉豆蔻酸含量基本没有影响，对棕榈酸、棕榈油酸、硬脂酸、亚油酸、花生酸和亚麻酸含量有一定的影响，但不显著；辐照后核桃粉中的油酸含量随辐照剂量的上升而显著增加，剂量达到8.0kGy时，油酸含量增加了4.3%。8.0kGy以下辐照对核桃粉色泽、气味、口感无明显改变。

In this paper,experiments for measuring absolute adsorption of N 2, CO 2 and natural gas on 8 different artificial cores using an accurate porosimeter and an precise chromatographic instrument under room temperature (283～292°K) and low pressure (0 167～0 3MPa) have been studied.From these experiments,the following result...

实验结果表明：用 N2 测得的吸附气量在原始气中所占的比例为0 。4 %～ 4 %不等，CO2 的为 1 %～ 5%不等，天然气的为 3%～ 6%不等；吸附前后自由天然气的摩尔组成有显著的差异，表明岩心对天然气有明显的吸附；天然气各组分间存在竞争吸附，重质组分的相对吸附量大于轻质组分。

In the dry sliding experiments of composites, friction coefficients decreased with the increase of load. Plastic deformation happened in the worn surface where Fe element was found, so PAM micro-fiber supported part of the load and prevented the further deformation. On the condition of high speed and high load, the worn surface of PAM1/nylon 6 composites was nearly melted and formed comparative uniform transfer on the surface of steel, which accounted for the rather low wear mass loss. The infrared analysis showed that the a small quantity of transition of crystal form from α into γ of nylon and its composites happened during the friction because of the high temperature and strong sheering strength.

通过对复合材料耐磨性能研究表明：复合材料的摩擦系数随载荷的增加而逐步下降，且磨损表面有明显的塑性变形；从能谱分析结果来看，复合材料表面有Fe的存在，表明PAM微纤承受了部分载荷，并阻止了基体的进一步塑性变形及粘着转移；在高速高载时，PAM1/尼龙6磨损表面处于粘流态，并在钢环表面形成了连续的转移膜，表现出较好的耐磨损性能，且在高温和强剪切力的作用下，材料基体发生了少量的α晶体向γ晶体的转移。

For schools to do splendid work and in a few years to discontinue or revert to conventional practice with no record of measured results for the work attempted is wasterful and deplorable. Because of their relative freedom from limitations, many schools operating under private auspices or as parts of schoolsof education may introduce variant materials and practices not elsewhere possible. For this reason, they are often the strategic places for testing proposals far removed from current pratice.

学校曾做过杰出的工作，但却在未来几年内停止或恢复到没有透过测量结果记录做基础的做法，是一种浪费和可悲，仅因为学校他们有自由的限制，许多学校的运作透过私人赞助，或学校部分教育可能引入不同材料和做法，这样的作法并非每一所学校都有此可能性，出於此原因，他们的策略是进行和目前作法不同的实验性作法。

Thunderstorms mainly occur in summer with obvious diurnal variation. Analyses indicate that the general trend of Shandong thunderstorms has wavily reduced during the last 40 years .The interannual and decadal variabilities of thunderstorms are obvious in Shandong Province.

However, this usefulness of GaN for optoelectronic devices seens to be limited by the fact that the defficulty in obtaining p-type material is to grow crystals by admixing GaP to GaN. As will known, GaP with n- or p-type conductivity can be easily obtained by suitable doping. Thus, it might be possible to get n- and p-type GaP_(1-x)N_x or GaAa_(1-xN_x crystals above some critical P content of the alloy system.

把两种或两种以上材料组合起来实现优异性能材料的方法是一种经常使用并行之有效的方法，本论文就是对GaP、GaAs与GaN形成合金系GaP_(1-x)N_x和GaAs_(1-x)N_x进行基础性研究的结果，人们预测这种合金系的禁带宽度应在磷化镓的2.261eV(或砷化镓的1.43eV)到氮化镓的3.39eV之间，如果能制成上述合金系则是很有意义的，它是很有希望的蓝色发光材料。

The calling and copulation behaviour of Ancylis sativa Liu had a dielperiodicity.The female moths began to calling at the first day and increasedto 100% at the second day,then the percentage of calling decreasedgradually from the third day to the fifth day,only 16.7% of females showingcalling behaviour at the sixth day.The effect of environmentaltemperature on calling behaviour of Ancylis sativa Liu was studied duringadult life at 16℃,21℃,26℃ and 31℃.The result showed differenttemperature during adult life affected significantly the calling behaviour ofvirgin females.There was considerable variability in the calling patternsamong the different temperature groups,the higher the temperature was,thelater females called,the shorter the calling behaviour lasted.The copulationbehaviour of Ancylis sativa Liu can be divided into following squence:female calling,male responsing,male approaching female,hairpencil displayingand copulating.

枣粘虫求偶和交配行为研究结果表明，在光周期为14L：10D、温度为21℃下，越冬代枣粘虫雌蛾的求偶高峰期为黑暗期6.0-8.0小时，求偶活动以羽化后1-3天表现强烈，第二天求偶百分率高达100％，第4天开始，求偶百分率下降，到第6天仅为16.7％；环境温度对枣粘虫雌蛾的求偶活动有明显的影响，随着温度的下降，求偶高峰期明显提前，求偶高峰期的持续时间变长，在21、26、31℃下，求偶百分率接近或达到100％，在16℃下，仅为43％；枣粘虫的交配行为可分为雌蛾求偶、雄蛾反应、雄蛾接近雌蛾、打开味刷及交配成功等阶段；交配活动也以羽化后前3天表现强烈；第1、2代在黑暗周期中的交配高峰期比越冬代推后1-2.5小时；越冬代枣粘虫的交尾持续时间多为3-4小时，第1、2代比越冬代短；越冬代交尾前期多为2-3天，第1、2代多为1-2天，少数羽化当天便可交尾；雌雄成虫均有多次交尾习性，雄蛾最高交尾6次，平均3.3次，雌蛾最多交尾3次，平均1.5次，在田间自然条件下，大多数越冬代雌雄成虫只交尾1次，第1、2代交尾次数有所增高，第1、2代成虫交配率明显高于越冬代。
