METHODS:Guinea-pigs were sensitized by ovalbumin and the effects of LMWH on the constriction of ileum smooth muscle induced by OA were observed in vitro;The effects of LMWH on the degranulation of pericranium mast cell induced by OA were observed throu gh the passive anaphylaxis ratmodel which was made by vaccinating antiserum at pericranium;Licking response was induced by 4-aminopyridine(4-AP) scat scruff in mice,then the effect of LMWH on licking response was studied the capillary p emeabilty increasing induced by glactal acetic acid and the effect of LMWH on ca pillary pemeability were studied.

用卵白蛋白(ovalbumin，OA)免疫豚鼠造成过敏模型，观察LMWH对OA所致的豚鼠离体回肠平滑肌收缩的影响；在大鼠颅骨骨膜接种抗血清使肥大细胞被动致敏，观察LMWH对OA引起肥大细胞脱颗粒的影响；以4-氨基吡啶诱发小鼠舔体反应，观察LMWH对舔体反应的影响；以冰醋酸使小鼠毛细血管通透性增加，观察LMWH对通透性的影响。

For single wall carbon nanotubes, we study the nonmagnetic and magnetic impurity effects on zigzag nanotubes by Green's function perturbation method and found that the impurity effects are different for semiconducting and metallic nanotubes. Arbitrary potential can induce a bound state in semiconducting nanotubes, and resonance state in metallic tubes.

在我们的工作以前，共振态对系统磁性的贡献往往被忽略，实验上观测到的掺非磁性杂质的高温超导的磁化率呈居里—外斯形式完全归结为杂质诱导出的局域磁矩，尽管可以解释磁化率，但与一些实验产生矛盾。

Therefore, pharmacodynamics should provide information about drugs how to generate beneficial effects, and how to provoke side effects.

因此，药效学应提供药物如何产生药用，以及如何引起副作用的资料。

Experiments of photosensitization exhibited that, when irradiated with red light, the photodamaging effects on cells of both photosensitizers are close to each other; but when exposed to room light the cytotoxic effect of AISPC is lower than that of HPD, suggesting a potential advantage of reducing undesired side effects in clinical application.

光敏杀伤的结果表明，在红光照射下，两光敏剂对细胞有相近的杀伤效率；在室内自然光下，AISPC对细胞的损伤明显低于HPD，显示出其较低的光毒付作用，具有适合临床应用的优点。

Effects of tillage systems and nitrogen applied amount on wheat growth and development and yield of wheat and maize 3.1 Effects of tillage systems and nitrogen applied amount on wheat growth and development In the second year of experiment, there was no significant difference in the wheat flag leaf photosynthesis rate, flag leaf senescence characteristics, photosynthate transferring amount, photosynthate transferring ratio and dry matter accumulation of between R, H and C.

3耕作模式与施氮量对小麦、玉米生长发育及产量的影响 3.1耕作模式与施氮量对小麦生长发育的影响在试验第二年，旋耕和耙耕模式在旗叶光合速率、旗叶衰老特性和光合产物转移量和转移率，以及干物质积累量上与常规耕作模式无显著差异。

Although physostigmine salicylate can reerse most of the features of TCA poisoning, its effects are short-lied in serious toxicity and it can produce significant side effects.

虽然毒扁豆碱可逆转TCA中毒的大多数体征，但是是通过其严重的毒性作用而起效的，可产生明显副作用。

It also shows that studying those associates would enhance semantic, but not perceptual processing of lures which verifies the discrepancy-attribution hypothesis.2, Compared with those emotional lures and associations in the unrelated lists, participants produce significant false recognition of emotional lures, even though initially no emotional lures appeared in the phonetic or pictophonetic relatedness effects.3, Participants show no significant difference to the emotional and nonemotional lures after studying phonetic or pictophonetic associations of single character Chinese, while phonetic relatedness effects of two-character Chinese words in the phonetic shows.

而本研究试图系统的探讨汉字关联效应中对情绪诱词的错误再认情况，本研究的结果表明： 1、在语义关联下，被试对中性、正性、负性的关键诱词都引发了很高的记忆错觉，表明这种实验范式对未出现的关键诱词的诱发错误再认是很强烈的；同时实验结果表明，对学过词表的关键诱词的知觉加工没有促进，而促进了对关键诱词的概念加工，验证了差异归因假设。

In practice, it may be quite difficult to distinguish stored charge effects from piezoelectric effects.

在实际工作中，区分储存电荷效应和压电效应可能是相当困难的。
