To assess which Ser/Thr residue could act as a phosphate acceptor upon agonist stimulation, truncation mutants of DORs were constructed by removing the last 15 ( D 15) or 31 ( D 31) residues containing the last three or six potential phosphorylation sites from the C-terminus of the wild-type receptor.

为了研究激动剂诱导下DOR的磷酸化发生于哪一个位点，我们首先构建了C末端区缺失六个丝/苏氨酸残基及三个丝/苏氨酸残基的DOR突变体 D 31和 D 15。

In the recent years, the company has successively developed the fully servo control extra-fine metallic wire drawing machine without tension bar, stainless steel fine wire drawing and annealing machine, the true meaning constant tension and constant line rate and fully-automatic single-head and single-control annealing wire coiling machine, fully-automatic active wire laying device and inductive and constant annealing extra-fine copper wire drawing machine and other new products, which have basically solved the defects of the finished product wires manufactured by ordinary equipment that tension inequality, disordered wire arranging, incapability for anti-drawing intensity and extension rate control and low finished product rate, etc and have improved the product quality to a higher grade.

近年来，本公司相继开发出全伺服控制无张力杆的贵金属极细线拉线机，不锈钢微丝拉丝退火一体机，真正意义上的恒张力，恒线速，全自动的单头单控退火线绕线机，全自动主动放线装置以及带感应式连续退火的极细铜线拉线机等新产品，根本解决了普通设备生产出的成品线内外松紧不一，排线不整齐，抗拉强度和延伸率无法控制，成品率低等缺陷，使产品质量更上了一个档次，设备的外观，制造精度和技术性能可以与进口设备相媲美，完全能够满足客户国外订单的高品质要求。

With this relationship, CTA can be used to monitor the localized flow velocity on the feed side of plate-type membrane module. Good results of velocity measurement were achieved by fixing the Pt wire of 25.4μm in diameter and 9~10mm in length on the net grid supporter on the feed liquid side in plate type membrane module.

利用直径为25.4μm的细铂丝制成长度为9~10mm的热丝传感器，直接固定在板式膜组件料液侧网状支撑物的纵向网线上，取得很好的CTA测速效果。

The apron is transmits the guide screw and the feed rod turns on lathe the transportation to turn becomes the apron the translation and the impetus tool rest enters gives, controls the tool rest movement to put through, the separation and the commutation.

将光杠的运动传至纵向齿轮齿条和横向进给丝杠的传动机构，接通、断开和转换纵横进给的转换机构，保证机床工作安全的过载保险装置，丝杠、光杠互锁机以及控制刀架纵、横向机动进给的操纵机构。

The system of drive are all driven by stepping motors.the machine system design includes every free degrees,computation of drive and transmission system .the third and four degree of freedom are performed by the feed screw having the spline of ball bearing which is design specially for robot .with the textual study,it can be believe the user will have an overall understanding to the way of thinking and steps of the machine system.
