In 2000, F. LUCA proved that Fermat number are anti-sociable numbers, and in 2005, M. H. LE proved all powers of 2 are anti-sociable numbers. We have used the method of M. H. LE to obtain some new results of the anti-sociable numbers. For every integer n containing prime divisors that are 1 mod 4, let p mod 4 be an arbitrary prime divisor of n. There is at least one anti-sociable number in n^2, p^2n^2, p^4n^2, and p^6n^2. Therefore we can prove that anti-sociable numbers have positive density in perfect square numbers. We also give a method to find the exact anti-sociable numbers.
LUCA证明了Fermat数都是孤立数;2005年,乐茂华教授证明了2的方幂都是孤立数,用乐茂华教授的方法给出孤立数的一些新的结果:对于任意含有4w+1型素因子的正整数n,设p为n的任意一个4w+1型素因子,则在n^2,p^2n^2,p^4n^2,p^6n^2里至少有一个是孤立数,因此可以证明孤立数在完全平方数里有正密度,另外也给出求解确定孤立数的方法。

The contents of N, P, K in leaves were examined by regular leaf analysis. The results showed that the N content was higher in leaf blade than in leafstalk. N content in leaf was gradually reduced along with the vine growth. N, F, K fertilized at 20 to 40 cm soil layers significantly increased N content in leaf. But N content in leafstalk was less affected by N fertilization depth and growing season. P content was higher in leafstalk than in leaf blade. Less change of P content was noticed in leaf along with vine growth. However, N, P, K fertilized at 40 to 60 cm soil layers significantly promoted P in both leaf blade and leafstalk. K content in leafstalk was much higher than in leaf Wade. No obvious influence was noticed by fertilizing depth. But K content in leafstalk was significantly increased due to applied K fertilizer in late growing season.
结果表明,酿酒葡萄叶片中氮含量远高于叶柄,叶片中氮素含量随着生育期的延长逐渐降低,而叶柄中氮含量随施肥深度增加和生育期延长而产生的变化很小,40cm的施肥深度能显著增加叶片中氮素含量;叶柄磷素平均含量高于叶片,全生育期叶片磷含量变化很小,而施肥60cm深度显著促进了叶片和叶柄中磷含量的提高;叶柄中钾含量远高于叶片,施肥深度对叶柄和叶片中钾含量未产生明显影响,但生育后期追施钾肥显著提高叶片钾含量;施肥深度达到40cm时酿酒葡萄的产量最高,而60cm的施肥深度产量显著下降。

Out of the 90 eyes, the scotopic F-ERG of 73(81.1%) eyes was non-detectable preoperatively and the number of such eyes decreased to 66(73.3%) postoperatively (P 0.05,t -test). During a 3-22-month follow-up (mean= 10.9±5.1 months, n =45), some waves of F-ERP in RP patients reappeared.

There are some AChR plaques of morphological abnormality, and no contact sites of N-CAM with AChR although the intensity and scope of N-CAM staining is increased.D: Yiqi Huayu Recipe-treated group on the 20th day after L5 nerve root compression. All the AChR sites are reoccupied by N-CAM and the morphology of AChR are restored. E: Untreated group on the 30th day after lumbar nerve root compression. AChR plaques display irregularity in shape, with a few round or spindle shaped cupulae. Meanwhile, some N-CAM stainings are still shown to be around the AChR. F: Yiqi Huayu Recipe-treated group on the 30th day after L5 nerve root compression.
随着时间的推移,AChR斑的形态渐趋规则,N-CAM反应也逐步增强,至造模后20 d达到最高峰,但益气化瘀方组仍然明显优于模型组,其不仅在数值上超过了胚胎期大鼠,且与AChR全部重叠;而模型组仍可见到不少重叠不全且形态异常的AChR斑。L5神经根受压后30 d,N-CAM的表达水平开始下降,基本局限于终板区内,其下降速度和范围在益气化瘀方组明显大于模型组;模型组不仅N-CAM的表达明显高于益气化瘀方组,且仍能见到一些成熟不全的AChR斑;而益气化瘀方组AChR斑形态已接近于正常。
