The monomer.of p.osp.or.lcholine der.vative, O-(5-（2.methacr.loxy）-3, 3-dimethyl-3-azap.ntyl)-O’-（ω-hydr.xy-octyl）-p.osp.atequater.ar. ammonium salt, was designed and synthesized successfully. It was char.cter.zed by the sp.ctr. ofHNMr.and Mass sp.ctr. （ESI+）, and ever. signal was assigned. Then the lubr.cating char.cter.stics of the p.osp.or.lcholineder.vative wer. investigated on the tr.bological setup.of ball-oh-flat. The Ultr.-High Molecular.Weight p.lyethylene（UHMWp.） flat was r.tated against a stainless steel ball with 6 mm diameter. The load was 2.3 N, which cor.esp.nded to amaximal Her.z contact p.essur. of 2. Mp.. Water. p.osp.or.lcholine der.vative, and Acr.lic Acid （AA） solution wer. used aslubr.cants, r.sp.ctively. Comp.r.d with AA, the p.osp.or.lcholine der.vative shows significant lubr.cation. It can be str.nglyhydr.ted under.water.due to the char.ed segment in chemical str.ctur.. The thick water.layer. within the chains ser.es asboundar. lubr.cants, and this is thought to be the molecular.or.gins of lubr.cating behavior.

The p.oblem on stabilization for.the system with distr.buted delays is r.sear.hed. The distr.buted time-delay under.consider.tion is assumed to be a constant time-delay, but not known exactly. A design method is p.op.sed for.a memor. p.op.r.ional and integr.l （p.） feedback contr.ller.with adap.ation to distr.buted time-delay. The feedback contr.ller.with memor. simultaneously contains the cur.ent state and the p.st distr.buted infor.ation of the addr.ssed systems. The design for.adap.ation law to distr.buted delay is ver. concise. The contr.ller.can be der.ved by solving a set of linear.matr.x inequalities （LMIs）. Two numer.cal examp.es ar. given to illustr.te the effectiveness of the design method.

The incoher.nt contr.l of finite-level quantum systems is investigated. Following a br.ef intr.duction to coher.nt contr.l p.r.digms in quantum contr.l, a contr.l p.oblem that can not be accomp.ished using only coher.nt contr.l is p.esented. For.such a contr.l p.oblem, it is p.oved that it can be accomp.ished using incoher.nt contr.l based on p.ojective measur.ment and coher.nt contr.l for.two classes of finite-level quantum systems, i.e., eigenstate contr.llable quantum systems and wavefunction contr.llable quantum systems.

Objective To investigate into the changes of dietar. p.tter.s and their.imp.cts on health of ur.an and r.r.l r.sidents in Jiangsu p.ovince, china dur.ng the 1990s. Methods On the basis of the r.sults of food consump.ion sur.ey, the calor.e intake was calculated accor.ing to the balanced diet method and the quality of diet was assessed by scor.s of desir.ble dietar. p.tter. (DDp.. r.sults It was found that food consump.ion and dietar. p.tter.s changed r.mar.ably dur.ng the 1990s. Gr.in consump.ion was decr.asing year.by year. but the consump.ion of animal food was mar.edly incr.asing. Although the scor. of desir.ble dietar. p.tter. (DDp. in ur.an r.sidents was mor. than 90, the deducted scor. due to over.consump.ion of animal food incr.ased. The mor.ality fr.m infectious diseases evidently decr.ased in the whole p.ovince, while the death r.tes of some chr.nic diseases, such as diabetes, hyp.r.ension, color.ctal cancer.and br.ast cancer. wer. incr.asing r.p.dly in ur.an ar.as. Conclusions Sufficient attention should be p.id to the negative effects of change in dietar. p.tter.s on p.op.e's health, esp.cially in the ur.an r.sidents.
