The rest SD rats were injected abdominally to induce chronic-kindling models by PTZ 35mg/kg for 28 days,then 30 having build-up model rats were divided randomly completely into three groups: model, YXL, VPA.

将SD大鼠随机取10只作为正常组，其余大鼠以PTZ 35mg／kg腹腔注射28天作慢性点燃造模，再取造模成功大鼠随机分为3组：模型组、丙戊酸钠组和愈痫灵颗粒剂组。

Methods 40 patients are divided equally into the lactated Ringer's group and the acetated sodium grouprandomly,adapting the combined intravenous and inhalation general anesthesia.

40例择期手术患者按随机数字表随机分为乳酸钠组和醋酸钠组，每组各20例，采用静吸复合全身麻醉。L组术中输入乳酸钠林格液，A组术中输入醋酸钠林格液，两组术中不

Objective TO compare the different changes of blood lactate and blood gases when given the lactated Ringer's solution and acetated sodium solution during operation. Methods 40 patients are divided equally into the lactated Ringer's group and the acetated sodium grouprandomly,adapting the combined intravenous and inhalation general anesthesia. The lactated Ringer's gis given in group L and the acetated sodium in group A. Neither groups are cross-given other crystal solution during operation, polygeline is the only colloid solution in both groups.

目的 比较术中输入乳酸钠林格液和醋酸钠林格液血乳酸盐及血气的变化方法 40例择期手术患者按随机字表随机分乳酸钠组和醋酸钠组，每组各20例，采用静吸复合全身麻醉。L组术中输入乳酸钠林格液，A组术中输入醋酸钠林格液，两组术中不交叉输入其他晶体液，输入胶体液均为菲克血隆。

Comparative analysis with the other non-stochastic model constrained by facies shows that the stochastic waterflooding model constrained by facies is consistent with the flooding conditions and rules, it also consistent with the rules of reservoir development and aeolotropism distribution, the result is more reliable, which can provide the effective foundation to adjust and tap the potential for this area.

与非相控随机建模方法预测的模型对比分析表明，相控下的随机水淹模型比较符合油田开发过程中的水淹状况及规律，符合储层发育及其非均质性分布规律，可信度高，为该区调整挖潜提供了重要的地质依据。

80 Individuals of ATA-A F2 plants were used for RAPD molecular mapping of the monoecious gene by bulk segregant analysis. 840 random primers were chosen for polymerase chain reaction amplification between monoecious pool and andromonoecious pool, the results showed that: primer S128 was tightly linked to the monoecious character, and primer S493 was tightly linked to the andromonoecious character.

以甜瓜单性花系ATA-A系与两性花品种YJX-1的杂交F2代的80个单株为材料，利用群分法进行单性花基因有关RAPD分子标记研究，筛选分析了840个10bp随机引物的PCR扩增谱带，结果表明，随机引物S128在1180bp，S493在930bp处产生与性别相关的特异性条带，S128的特异条带与单性花性状相关，S493的特异条带与两性花性状相关。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).
