It provided the reference to improve the anti-cracking capability of high strength and high performance concrete from the point of view of constructional technology and curing requirement.The result shows that the more the binder material or sand rate, the more serious the shrinkage cracking. In the concrete with a low water-to-binder ratio, a bit of difference in the dosage of water will result in big difference on the strength and the anti-cracking capability. The occurrence of cracking is mainly at early age (before 1 day). If the surface is plastered again after 2 hours of casting, the anti-cracking capability will nicely improved.

研究结果表明：随着胶结料总量和砂率的增大，高强高性能混凝土的收缩开裂趋于严重；在水胶比较低的情况下，用水量的稍微差别对混凝土的强度和抗裂性能都具有很大的影响；掺入粉煤灰对抗裂有所改善，但是其掺量对抗裂的影响并不是呈定向规律，而是存在着最优掺量；高强高性能混凝土的裂缝主要发生在早期(1d前)，若在浇注后2个小时再次抹面可以很好地改善其抗裂性能。

The model groups were fed with different-dose lycopene [10, 15, 20 mg/] for 12weeks. Then related indexes including length bone mineral density, bone mineral, serum estradiol, sertum ALP and uterus index were analyzed.

结果 番茄红素高[20mg/]、中[15mg/]、低剂量组[10mg/]、尼尔雌醇组[1.05mg/kgbw]能对抗骨密度、骨矿含量、血清雌二醇的下降、血清碱性磷酸酶的升高，与模型组比较，P.05；番茄红素各剂量组、尼尔雌醇组能对抗子宫指数的减轻，与模型组比较，P.05。

Methods seventy-two 15-week-old sd rats were divided into six groups,included control group and five ovariectomized model groups.the model groups were fed with different-dose lycopene［10,15,20 mg/］ for 12weeks.then related indexes including length bone mineral density,bone mineral,serum estradiol,sertum alp and uterus index were analyzed.results compared with model group,three different dose groups and nilestriol［1.05mg/］ group showed increased bone mineral density,bone mineral,serum estradiol and uterus index,but decreased serum alp (p.05).conclusion as a female sex hormone-like component,lycopene may ameliorate the bone quality and inhibit osteoporosis in ovariectomized rat.

将72只15周龄sd大鼠随机分为6组，空白组做假手术，其余5组做卵巢切除术，术后用药12周后处死，测定右侧股骨骨密度、骨矿含量、血清雌二醇、碱性磷酸酶含量及子宫湿重。结果番茄红素高［20mg/］、中［15mg/］、低剂量组［10mg/］、尼尔雌醇组［1.05mg/kg·bw］能对抗骨密度、骨矿含量、血清雌二醇的下降、血清碱性磷酸酶的升高，与模型组比较，p.05；番茄红素各剂量组、尼尔雌醇组能对抗子宫指数的减轻，与模型组比较，p.05。结论番茄红素可以改善骨质量，抑制大鼠去卵巢骨质疏松的发生。具有类似雌激素的效应。
