Result of thermogravity analysis showed that the thermal stability of polyvinylamine chloride lowers with increasing in amination degree. Moreover, properties of dilute aqueous solutions of three types of poly chloride with different amination degree were compared by use of viscosimetric, conductometric, and potentiometric measurements. Results showed that both the electrostatic interaction of neighboring groups on the chain and the reduced viscosity of poly chloride are increased with increasing the degree of amination of poly . The equivalent conductivity is decreased with the increasing the concentration of poly chloride and increased with the increasing the amination degree of poly .

研究了聚乙烯胺盐酸盐的热稳定性和水溶液性质,发现:随着胺化度的提高,聚乙烯胺盐酸盐的对热稳定性逐步降低;聚乙烯胺盐酸盐是一种典型的聚电解质,其水溶液的pH值随平均分子量的变化并不明显,而随着聚乙烯胺胺化度的升高,pH值降低;随着聚乙烯胺盐酸盐的平均聚合度由82.3增加到201.8,它的m值(用于表征聚电解质侧链基团之间相互作用大小的常数)从5.13升高到5.58,而当聚乙烯胺盐酸盐的平均聚合度增加到311.4时,它的m值反而降低到了5.48;随着胺化度由55.65%升高到82.36%,m值由3.65提高到5.50;随着聚乙烯胺盐酸盐的平均聚合度的提高,聚乙烯胺盐酸盐的平均解离常数由7.48降低到7.26,同时随着胺化度的提高,聚乙烯胺盐酸盐的平均解离常数也由8.33降低到7.37;随着聚乙烯胺盐酸盐浓度的提高,溶液的摩尔电导率逐步降低,随着聚乙烯胺胺化度和聚合度的提高,溶液的摩尔电导率有所升高;在pH值为4左右时,聚乙烯胺盐酸盐的比浓粘度分别达到极值,而与聚合度的大小关系不大;聚乙烯胺盐酸盐的特性粘数明显高于其原料聚丙烯酰胺的特性粘数,分子量对特性粘数的影响十分明显,胺化度对特性粘数的影响并不显著。

If the grounds of an opinion are not conclusive to the person's own reason, his reason cannot be strengthened, but is likely to be weakened, by his adopting it: and if the inducements to an act are not such as are consentaneous to his own feelings and character (where affection, or the rights of others, are not concerned) it is so much done towards rendering his feelings and character inert and torpid, instead of active and energetic.

因此,如果说,若是一个意见的根据对于本人自己的理性说来不不足以当结论而他却采纳了那个意见,这不但不能加强他的理性反倒会减弱他的理性;那么,同样也可以说,若是导出一项行动的东西并非在本人情感上和性格上吻合无间的东西(在和喜好或他人的权利无干的时候),这也只会使他的情感和性格趋于怠惰和迟钝,而不会使它们变得活跃而富有精力。

The results showed that: with the regression analysis of Betula platyphylla, Pinus koraiensis, Abies nephrolepis, Picea koyamai var koraiensis, and Betula costata, there was a significant negative correlation between neighborhood interference index and the growth (0.40~0.89) and the correlation extent depended on the neighborhood influence zone and slope. The neighborhood influence zone corresponding to maximal regression coefficient R~2 was the neighborhood influence radius. Based on the linear subsection regression between neighborhood interference index and influence zone of five species, the neighborhood interference index increased with the increasing zone and there was a previous increasing trend in a certain scope, while the increasing trend slackened beyond the zone. The neighborhood influence zone corresponding to transition point was the neighborhood influence radius. The neighborhood interference index positively correlated with the neighborhood influence zone and the range of R~2 was 0.40-0.64. With the analysis of tree cores of Juglans mandshurica, Fraxinus mandshurica at middle and lower slope in a plot which was fostered in 1995, the distance which the growth release farthest neighborhood and object stub was judged, thus the neighborhood interference radius was inferred. According to the studies, we found that the neighborhood interference radius was different among different trees, even if the neighborhood interference radius of the identical tree species also had the difference at different slopes.

结果表明:通过对白桦、红松、冷杉、红皮云杉和枫桦树种进行邻体干扰指数与生长量回归分析发现,邻体干扰指数与生长量呈显著负相关(0.40~0.89),相关程度因邻体影响范围和坡位而异,R~2达到最大值所对应的影响范围即为邻体影响半径;通过对白桦、红松、冷杉、红皮云杉和枫桦树种进行邻体干扰指数与影响范围的线性分段拟合,邻体干扰指数随影响范围的增加而增加,其在一定的范围内上升较快,而超出该范围后上升的幅度变慢,变化的转折点所对应的影n向范围可以判定为邻体影响半径,线性回归显著(0.40~0.64);通过对1995a抚育的胡桃楸、水曲柳样树进行研究,分析邻体树种的中坡位和下坡位的生长锥芯,判断产生生长释放的最远邻木与基株树桩所对应的距离,推断邻体影响半径;根据研究发现,邻体影响半径因树种不同有一定的差异,即使同一树种的邻体影响半径在不同坡位也有一定的差异。

He who is happy for your sadness is your counterworker;He who is happy for your happiness is your friend;Yet, you should memory these who are sorrowful for your sadness.

为你的难过而快乐的人,是敌人;为你的快乐而快乐的人,是朋友;为你的难过而难过的,就是那些该放进心里的人。

For if goodness can only be in God, if it cannot exist separate from Him, if He can only bless and sanctify, not by a creaturely gift, but by Himself becoming the Blessing and Sanctification of the creature, then it is the highest degree of blindness to look for any goodness and happiness from anything but the immediate indwelling union and operation of the Deity in the life of the creature.

称永久代祷的人是宗教狂热者是何等毫无理由,至少在单单真实的从神获得启示的生命,是无法得到良善和喜乐,那就不可能同意此说,因为良善无法与神分离而单独存在,除非借他自己所变成有福而圣洁的人否则没人能有此种生命,惟有直接从内住的神得到启示,否则没有高级受造之物,可从其他地方找到良善和喜乐,根据永远的启示:动物怎样需要空气而高级受造物也怎样需要有良善、圣洁和喜乐的本性。

The analyzed results about the forming mechanism of TiC indicate that the dendritical TiC is the primary TiC which freely grows in a continuous growth way in supercooling liquid metal before the peritectic reaction, and the short bar-like TiC nucleates and grows in β—Ti after peritectic reaction.

在对TiC形成机制的分析中认为,树枝状TiC是包晶反应之前过冷熔体中,以连续生长方式自由生长而成的初生TiC,而短棒状TiC则是包晶反应后在β-Ti的内部生核并长大而成。

It is nothing else than impurities prenatally inherent in ore that seriously affect the quality of the latter, which is formed as a result of geological vicissitudes including diastrophic movement, eruption of volcano, sedimentation, glaciation and weathering etc., under the action of which pyrogenic rocks, volcanic complex, aqueous rocks, sedimentary rocks etc., come into being, some of which exist in a stage of symbiosis, the main cause of the absence of pure rocks in nature, wherein lies the reason for the need of separation technology and apparatus, namely, ore-dressing devices and equipment, so far impotent to meet the requirements of metallurgical industry the scientists make every endeavor to elevate to a new high by laser separation.

没有什么比矿石形成之前就存在的杂质对矿石品质的影响更为重大。矿石是火成岩、火山群、水成岩、沉积岩等成形时,在包括地壳运动、火山爆发、沉积、冰蚀、风化等地质变化的作用下而形成的。而有些地质变化在一个发展阶段中存在共生现象。自然界无杂质岩石缺乏的主要原因在于需要分离技术和设备来完成,即:需要选矿设备和装置。而迄今为止,这些设备还难以适应冶金业的需要,虽然科学家们尽一切努力用激光分离技术将冶金业提高到一个新的高度。
