The effects of 20~100 mg/L MS-222,Tricaine Methanesulphonat,were tested at water temperature 15~25 ℃ on two species of sturgeons,Acipenser sinensis and A.schrenckii.

以20~100 mg/L的MS-222在水温15~25℃条件下对中华鲟和施氏鲟(A.schrenckii)的麻醉效果进行试验，中华鲟或施氏鲟分别达到不同程度的麻醉状态甚至出现死亡。30~40 mg/L的MS-222具有较好的麻醉效果，鱼的活动量明显下降，可保持镇静并维持身体平衡和正常体位，麻醉48 h后，在清水中数分钟内可恢复正常游动状态，适合于长途运输。50~100 mg/L的MS-222对中华鲟和施氏鲟具有较强的麻醉作用，适合于进行短时间的操作，如捉拿、称重、测量、外科手术、体外标记等。

In the bilateral group, the blood flow on both sides was detectable during antegrade selective cerebral perfusion.

在基底动脉环完整，存在有效侧支循环条件下，单侧灌注操作较为简便，双侧灌注在ASCP期间两侧脑灌注较为均衡，但两种灌注方法对S100蛋白浓度的影响无显著性差异。

In 2005, the Organizing Committee will hold two press conferences in March and May respectively. Also, we will publish special articles in authoritative newspapers, launch publicity campaigns aperiodically through the mass media, and invite around 100 journalists to cover the whole event. You are warmly welcomed to be a part of these activities.

组委会将组织以下活动请企业参与：2005年3月和5月举行的新闻发布会；在业内权威媒体上进行大型专题文章操作；不定期针对广大媒体进行广泛宣传；在展会期间组委会将组织近百名记者朋友到会采访。

It does not require details to be provided for the type of handling which is implicit in normal use, and/or 最后总装 care - e.g., it is not necessary to recommend that a "sterile" device be removed aseptically from its packaging.

此需求仅与设备或其特性在使用前通过某些渠道进行改变的情况有关。不要求向操作&消毒&设备的包装远离防腐剂，没有必要介绍。种类提供详细内容，因为在常规使用中是不言而喻的。

Enzyme as a biological catalyst is very sensitive to the environment , physical, chemical and biological factors.In the other hand it is difficult to purify from the reaction products. What's more it can not make a continuous operation.All those astrict the reaction.Under this condition, enzyme immobilization was put forward and developed.

酶作为一种生物催化剂，对环境十分敏感，易受物理、化学和生物等因素的影响而失活，而且反应后混入产品，纯化困难，不能实现连续操作，这些难以克服的现象大大限制了酶促反应在工业中的应用，在这种条件下，固定化酶的概念和技术得以提出和发展。

Two vaccines in China results are avirulent sequence. All these results show that the method can differentiate virulent and avirulent,vaccine.

本试验采用RT-PCR结合内切酶分析，有效的避免了这些方法的不足，并且操作简便、快速，可在24～36h内确定分离株的毒力，也减少了散毒和分离样品在处理过程发生交叉污染的可能性。

Autoprint to one-key: bagmaking cards and membership cards making machine system for automation newspaper business card printing and membership card production point of view marks in the entire business card printing and membership card making process chain into account, along with the cost of each newspaper, has been declining, Business card printing and membership card production efficiency is also on the increase.

一键式操作：以autoprint自动制卡和会员卡制作机系统进行自动化报纸制卡和会员卡制作生产的观点标志着在将整个制卡和会员卡制作车间加工链考虑在内时，随着每份报纸成本的不断下降，制卡和会员卡制作生产效率也在不断提高。

During spectrum tests, operating conditions, sample preparation, and other conditions can affect the test results, identified by XRD 4-4 'bipyridine and metal at a high temperature can be coordinated into a metal organic complexes.

在进行光谱测试时，操作条件、样品制备等条件均能影响测试结果，通过XRD确定4-4'联吡啶与金属在高温下可以配位成金属有机配合物。

Based on the absorbance change of indicators with the concentration of hydrogen ion released from the enzyme-catalyzed reaction, a convenient colorimetry method is established for the assay of acidic phospholipase 〓 and glycogen phosphorylase b Brilliant yellow and bromothymol blue are chosen as indicators for assays of acidic phospholipase 〓 and glycogen phosphorylase b by following the absorbance changes at 495 nm and 615nm respectively The method is simple, sample-saving, sensitive and valid for a wide range of enzyme concentrations.

为了研究糖原磷酸化酶的激活动力学和酸性磷脂酶〓的复性过程，我们根据酶催化反应中释放氢离子浓度的变化引起相应的指示剂的光吸收发生变化的原理，建立了一种简捷的比色法，用于测定酸性磷脂酶〓和糖原磷酸化酶b的活性。选用亮黄和溴麝香草酚兰分别作为酸性磷脂酶〓和糖原磷酸化酶b测活的指示剂，在495 nm和615 nm处检测二者的光吸收值的变化，可以测定酶活。本方法的优点是，可在比较宽的酶浓度范围内进行活力测定，而且操作简单、节省样品、灵敏度高。

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).
