The conversion boundary of self-incompatibility was researched by sowing by stage. Sunshine of day and temperature was studied critically by investigating leafage and researching traits indoors. The results showed that the daily minimum temperature was the principal factor of affinity conversion and the affinity conversion boundary was 16.5~18.1℃.HE97 was primarily regard as self-incompatible line in this research. The method was by inbreeding and sib HE97, Half the silk of HE97 and Zheng58. Inbreeding and cross have been done simultaneously. The extending condition of pollen tube was observed by dying the silk after pollinating 4 hours. The individuals with pollen tube were observed having seeds, while the individuals without pollen tube were observed having few seeds or no seeds. So this study regard HE97 as sporophytic self-incompatibility .The planting ration of female parent HE97 and male parent 87-1 was 4:1.The nature cross-pollination was studied by the theory of endosperm xenity, the study show that the setting percentage of HE97 was 625%, in which the seed in self was 70% and the seed in hybrid was 30%. This was consistent with the study of silk anatomy structure, then come to the same conclusion: compatible pollen germination and fertilization can stimulate the self-incompatible pollen germination and fertilization in the same corn cob.

通过分期播种，进行了光温敏自交不亲和材料HE97亲和性转换区间的研究，依据田间跟踪调查叶龄及室内考种研究了HE97亲和性转换区间的光温临界值，结果表明：1日最低温度是影响HE97自交不亲和性的主要原因，亲和性转换区间在16.5℃～18.1℃之间。2通过HE97自交和姊妹交以及将HE97与郑58作为双亲，各自的花丝一分为二，分别正反交，授粉后4个小时分别取其花丝进行固定、染色，观察花粉管的伸长情况，根据结实率与花粉管伸长的对应关系，结果发现观察到花粉管的对应植株收获到了种子，而没有观察到花粉管的对应植株结实率极低或没有结实，本研究把HE97初步划为孢子体自交不亲和类型。3以HE97为母本，87-1为父本，按4母：1父行比，通过花粉直感效应研究天然异交率，结果母本HE97结实良好(62%)，其中自交粒占70%，异交粒占30%，结合花丝切片观察表明，亲和花粉的萌发及受精会导致落在同一果穗柱头上不亲和花粉的萌发不再受抑制。

No reactivation was observed in the four patients from Group II with undetectable HCV RNA.

在未检测到HCV RNA的第2组病人中，没有观察到病毒的再次激活。

It reflects statistical error and takes into account unobserved supply, underreported demand and unreported stock changes.

它反映了统计误差，而且考虑到没有观察到的供应量、少报的需求量和瞒报的库存量变化情况。

Nevertheless, According to Kaplan-Meier analysis, the 1-year graft survival rate was signicantly worse in the C4dgroup(62.9%) than in the C4dgroup (83.3%; log-rank P=0.038).(5) The distribution of deficiency syndrome as follows: spleen-kidney Qi deficiency (53.2%), hepatic and renal Yin deficiency (28.6%), spleen-kidney Yang Deficiency (18.2%). The distribution of sthenia syndrome as follows: syndrome of blood stasis(58.4%), damp-heat syndrome(20.8%), pathogenic damp(11.7%).

应用Kaplan-Meier法观察移植肾穿刺后的生存曲线，log-rank比较两组的移植肾生存率，P=0.040，两组穿刺后生存率差异具有统计学意义。6、观察77例慢性移植物肾病中虚证分布情况：脾肾气虚占53.2%，其次是肝肾阴虚占28.6%，脾肾阳虚占18.2%，而没有观察到阴阳两虚患者；实证分布情况：血瘀证占58.4%，其次是湿热证占20.8%，湿浊证占11.7%和水气证占7.8%，没有观察到风动证。

In the control group, not a single case of bacteria penetrating apically was observed.

在对照组，没有观察到一例细菌渗漏到根尖的情况。

In the control group, not a singlecase of bacteria penetrating apically wasobserved.

在对照组，没有观察到一例细菌渗漏到根尖的情况。

In summary, the results of this study show a partial dissociation of attention and oculomotor preparation with TMS at late time point.

然而，此研究并没有观察到如Juan等人观察到的早期跨颅磁刺激的效果，可能的原因为我们没有办法将那些未经视觉选择的反应删除。

Under hypoxic conditions,prolyl hydroxylase activity decreases because they require oxygen as a co-factor and the HIF-1αprotein is stabilized.HIF-1αstabilization is followed by activation of the transcription of numerous target genes such as vascular endothelial growth factor,erythropoietin,and glucose transporter 1 (Glut-1) that are involved in angiogenesis,erythropoiesis,energy metabolism and cell survival.

但是，MSCs改善心功能的能力有限，大量的证据表明MSC移植对心功能的改善是轻中度的，大部分研究结果显示MSCs移植对心功能的改善只有5-6%左右，甚至有些临床试验没有观察到心功能的改善，这远远达不到我们的预期，其中一个很重要的原因是绝大多数的细胞移植到体内后在很短的时间内发生死亡，研究报道90%的MSCs在移植后的1天内死亡。

However, as the field intensity exceeds 150 oersteds or so, the chang...

这个内耗最大值在饱和磁场强度下并不降低，这种现象是以前所没有观察到的。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
