The results indicated that there were six types of sensilla, namely, finger-like sensilla, platcodeum sensilla, trichoid sensilla, ampullaceous sensilla and chaetic sensilla on the antenna of two wasps. The type, number, and distribution patterns of the antennal sensilla were similar in the two species, but the differences between two sexes were significant.

结果发现，在两种寄生蜂的触角上着生着6种感器，分别为指形感器、板状感器、毛形感器、坛形感器、刺形感器、蒲姆氏鬃；两种桑天牛卵寄生蜂触角感器的种类、数量及分布模式在种间没有明显差异，但在种内雌雄个体间差异较为显著。

The studies on intraspecific variation of Batrachospermum gelatinosum and B.intortum have been made. The results show that the intraspecific variation is widespread. Most of numerical characters are in great variable range. Compared with the reproductive organs, the vegetative organs are more variable to vary.

对胶串珠藻和绞扭串珠藻的种内形态变异进行了初步研究，结果表明，种内形态变异现象普遍存在，变异范围较大的，多属数量性状，且营养结构较生殖结构特征具有更大的变异性。

Among the enemy population, intra-species competition is fiercest for Coccinella septempunctata and weakest for E. plagiator. In terms of time, competition between P. japonica and C. septempunctata or Leis axyridis is relatively fierce. However, that between E. plagiator and P. japonica, C. septempunctata or L. axyridis is weaker.

在天敌种群中以七星瓢虫种内竞争最为激烈，麦蚜茧蜂的种内竞争最为缓和；龟纹瓢虫分别与七星瓢虫和异色瓢虫在时间维度上的竞争较为激烈，而麦蚜茧蜂分别与龟纹瓢虫、七星瓢虫和异色瓢虫的竞争比较缓和。

To date, there have been a few clinical trials exploring the efficacy of NMDA enhancers as adjuvant therapy. For instance, D-serine (an endogenous agonist of the NMDA-glycine site) and sarcosine (N-methylglycine, an endogenous glycine transporter I inhibitor) are not only well-tolerated but also synergistic in improving positive, negative symptoms and cognitive function in chronic patients receiving typical or atypical antipsychotics. We just completed the first trial applying NMDA enhancers in acutely exacerbated schizophrenia patients with collaboration with Harvard University, and the results showed that sarcosine was superior to D-serine in efficacy.

目前已有将NMDA促进剂作为辅助用药的临床研究，例如，D-serine (一种内生性NMDA-glycine site致效剂)、sarcosine (即N-methylglycine，一种内生性glycine transporter I 抑制剂)等，结果显示它们不但安全，且能加强传统及新一代抗精神病剂对慢性患者活性、负性症状及认知功能的疗效；我们日前与哈佛大学合作完成目前唯一将NMDA促进剂用於急性患者的研究，结果发现，sarcosine的疗效又优於D-serine。

发现星型胶质细胞内的钙库包括：〓敏感和non—〓敏感的两种内质网钙库，可分别被MCh和CAF激活；线粒体钙库参与胞浆内Ca2+缓冲系统。

This article introduces the structure, principles and performance of several low-noise gear pumps, analyses that gear pump is the noise source in the new internal combustion forklift and battery forklift, provides some methods which can reduce the gear pump noise, and establishes the matching relation between gear modulus and pressure angle of the gear pump, which is applied to the new internal combustion forklift and forklift battery.

摘 要：本文介绍几种低噪声齿轮泵的结构、原理和性能，分析了新型内燃叉车和电瓶叉车中齿轮泵是噪声源，给出了可降低齿轮泵噪声的方法，建立了该种齿轮泵的齿轮摸数和压力角匹配关系，并在某新型内燃叉车和电瓶叉车上得到应用。

Methods Three kinds of two phase culture mediums were applied to the culture and preservation of Entamoeba invadens and their effects in proliferation of the protozoan were observed.

目的 探索侵袭内阿米巴较好的培养和保方法方法分别应用三种常用的双相培养基对侵袭内阿米巴进行培养和保种的效果比较。

A typical lathe provides, through the feed rod, forty-eight feeds ranging from inch to inch per revolution of the spindle, and, through the lead screw, leads for cutting forty eight different threads from 1.5 to 92 per inch.

一台典型的车床的主轴没旋转一圈，通过光杠可以获得从到英寸尺寸范围内的48种进给量；而使用丝杠可以车削从1.5到92牙/英寸范围内的48种不同螺纹。

In contrast, deletion of the propeptide yields mature but inactive NK, the inclusion bodies of NK or denatured rNK couldn't be renatured in any condition, but with the aid of exogenously purified propeptide or Ser221Ala proNK, the inactive mature protein could be renatured by an intermolecular pathway in vitro.

此外，我们利用融合基因表达系统在大肠杆菌中高效表达了谷胱甘肽S-转移酶／NK和硫氧还蛋白／NK两种融合蛋白，经体外复性、纯化，均获得活性蛋白。以上结果显示，pro肽在体内体外，通过分子内或分子间的方式均能帮助NK分子的折叠与再折叠，作为一种分子内的分子伴侣，pro肽为NK分子正确折叠所必需。
